How Celiac Disease Might Affect the Feet

Celiac disease primarily affects the digestive system but can have significant consequences for the entire body, including the feet. Individuals with celiac disease frequently experience complications in the feet due to two main mechanisms: nutritional deficiencies and autoimmune-related neurological and musculoskeletal effects.

Peripheral Neuropathy

Peripheral neuropathy is one of the most common foot manifestations in people with celiac disease. This condition results from damage to the peripheral nerves, causing symptoms such as numbness, tingling, burning, pain, and even weakness in the feet. The nerves in the feet are often the first affected due to their length and vulnerability. This damage can lead to:

  • Numbness and decreased sensation, making it harder to detect injuries or pressure sores.f
  • Tingling or prickly sensations, which are uncomfortable and may disrupt normal walking.
  • Burning or shooting pain in the feet, sometimes described as electric or stabbing
  • Instability and a loss of balance, increasing the risk of falls.

Treating the underlying celiac disease through a strict gluten-free diet may reduce the risk of further nerve damage and even improve symptoms for some individuals. However, prolonged exposure to gluten before diagnosis can cause lasting damage.

Musculoskeletal Manifestations

Celiac disease also impacts the bones and joints, often causing osteoporosis, osteomalacia (bone softening), and arthritis-like symptoms. Reduced bone density increases the risk of fractures in the feet. Joint pain and stiffness, particularly in the small joints like those in the ankles and feet, are also reported.

Patients often experience:

  • Morning stiffness in the feet and ankles.
  • Swelling and soreness in joints after physical activity or gluten exposure.
  • Polyarthralgia (pain in multiple joints), sometimes including those of the feet.
  • Back, lower back, and pelvic pain that may indirectly affect gait and weight distribution, aggravating foot issues.

Additionally, children with celiac disease may show joint abnormality in the feet, such as effusion or synovitis, detectable even without obvious arthritis symptoms. In untreated cases, joint abnormalities and enthesitis (inflammation at the site of attachment of tendon or ligament to bone) are more frequent.

Dermatological Manifestations: Dermatitis Herpetiformis

Some people with celiac disease develop dermatitis herpetiformis, a blistering, itchy rash that often appears on the limbs, including around the ankles and occasionally on the feet. The discomfort and ulceration from this rash can make standing and walking painful and may lead to secondary infections if lesions are scratched or unhealed.

Nutritional Deficiencies and Impact

Malabsorption of key nutrients is a hallmark of celiac disease and can significantly affect foot health:

  • Iron deficiency can lead to anemia, causing fatigue and limiting mobility.
  • Low calcium and vitamin D levels can cause bone weakness and cramps in the feet.
  • B12 deficiency contributes to neuropathy and muscle weakness.

Prolonged deficiency makes bones more brittle, increasing the risk of fractures during routine activities. In children, poor nutrition may result in delayed growth and development, affecting foot structure and gait.

Mobility and Quality of Life

The combination of nerve and skeletal damage, pain, numbness, and balance difficulties can severely limit the mobility of those with undiagnosed or poorly managed celiac disease:

  • Difficulty walking and maintaining balance increases fall risk and may require assistive devices or physical therapy.
  • Loss of sensation in the feet makes new injuries harder to notice and slower to heal, raising the danger of chronic wounds.
  • Instability may persist even after a gluten-free diet is initiated, especially if diagnosis was delayed and nerve or bone damage is severe.

Special footwear, orthotic inserts, and routine foot care are recommended to compensate for these risks and improve function.

Secondary Complications

Longstanding nerve and bone problems in the feet increase the risk of secondary complications:

  • Ulcers and pressure sores may develop silently due to numbness.
  • Poor circulation, combined with nerve damage, increases risk for infections that may be slow to resolve.
  • Deformities in foot structure may occur due to abnormal gait and pressure distribution, such as hammertoes or pes planus (flat feet)

Managing Foot Health in Celiac Disease

Routine visits to a podiatrist are crucial for early detection and management of foot complications in people with celiac disease.

Treatment options include:

  • Strict adherence to a gluten-free diet.
  • Pain management and physical therapy to maintain function.
  • Vitamin and mineral supplementation to address deficiencies.
  • Specialized shoes or orthotic inserts for those with instability or deformity
  • Patient education on inspecting feet regularly to detect injuries or changes early, since sensation may be blunted.

Celiac disease is far more than a digestive disorder—it creates cascading effects throughout the body, with the feet being uniquely vulnerable due to the complexity of nerve and bone systems in this area. Peripheral neuropathy, musculoskeletal changes, dermatological manifestations, and nutritional deficiencies combine to make foot health a crucial and sometimes challenging aspect of living with celiac disease.

Early diagnosis, strict dietary management, and proactive foot care are essential for preventing long-term complications. Individuals should seek both routine medical and podiatric evaluation to address symptoms and mitigate risks, aiming for mobility, comfort, and quality of life even while managing a chronic autoimmune disorder.

Caring for the diabetic foot

Caring for the diabetic foot is a critical aspect of diabetes management due to the high risk of complications such as foot ulcers, infections, and amputations. Individuals with diabetes often suffer from neuropathy and impaired circulation, which can result in even minor injuries escalating rapidly if not properly managed. Effective diabetic foot care requires a comprehensive approach that encompasses daily foot hygiene, appropriate footwear, regular medical assessments, and prompt attention to any abnormalities.

Understanding Diabetic Foot Risks

Diabetes affects the feet primarily through two mechanisms: nerve damage (neuropathy) and poor blood circulation (peripheral arterial disease). Neuropathy diminishes sensation, so injuries may go unnoticed, while poor circulation hinders healing and increases the risk of infection. Together, these complications significantly raise the risk of foot ulcers and amputations in people with diabetes.

Daily Foot Care

Good foot care habits can dramatically reduce the incidence of complications. Patients are advised to:

  • Wash their feet daily using mild soap and lukewarm water, gently drying them afterward, especially between the toes.
  • Moisturize dry skin to prevent cracking, but avoid applying lotion between the toes, as this can encourage fungal infections.
  • Inspect their feet every day for any cuts, blisters, redness, swelling, or temperature changes. Early identification of abnormalities enables prompt treatment and reduces the risk of ulceration.

Nail and Skin Care

Proper nail care is essential:

  • Toenails should be trimmed straight across and filed to prevent sharp edges, which might lead to ingrown toenails or trauma
  • Corns and calluses should never be self-treated due to the possibility of unnoticed injuries and subsequent infection. Instead, treatment should be performed by a podiatrist or healthcare provider.

Maintaining clean and silky skin prevents cracking and infection. However, excessive moisture between the toes can be problematic and should be minimized.​

Footwear and Protection

Choosing the right footwear is crucial:

  • Always wear closed-toed, well-fitting shoes or slippers, even at home, to protect feet from injury.
  • Avoid shoes with high heels or pointed toes that may cause pressure sores or blisters. Shoes should be checked before wearing to ensure no foreign objects are inside.
  • Well-fitted, moisture-wicking socks help prevent blisters and fungal infections. Diabetic-specific socks may boost circulation, reduce moisture, and provide additional cushioning.
  • Patients with significant deformities or high-risk feet may require custom therapeutic shoes or insoles that provide extra protection and offloading.

Activity, Circulation, and Lifestyle

Regular exercise helps promote blood flow to the lower extremities. However, patients should not walk when they have sores, and walking should be done in sturdy, comfortable shoes. Smoking cessation, blood glucose control, and management of blood pressure and cholesterol are essential for optimizing vascular health and minimizing risk.​

Early Detection and Professional Assessment

Everyone with diabetes should undergo annual foot assessments by their healthcare team. Those at higher risk, such as those with previous foot ulcers, deformities, or neuropathy, may require more frequent evaluations and podiatry referrals. Clinical assessments typically include inspection, sensory testing, vascular evaluation, and education about foot care.

Management of Foot Problems

If a foot problem is detected, such as a blister, ulcer, cut, or persistent redness, individuals should seek prompt medical attention. Delays can lead to severe infections and potentially amputation. Treatments include cleansing wounds, using appropriate dressings, offloading pressure from ulcers (with special shoes, boots, or casts), and possibly prescribing antibiotics or surgical interventions for advanced infections.

Patient Education

Education is a cornerstone of diabetic foot care. Patients, families, and caregivers should all understand:

  • The importance of daily inspection and hygiene.
  • How to recognize warning signs of complications, including color changes, swelling, non-healing wounds, or nail changes.​
  • When and how to seek medical help for foot problems.

Special Considerations

  • Never go barefoot, not even indoors, to minimize the risk of puncture wounds or accidental trauma.
  • Avoid soaking feet, as this may dry out the skin and increase the risk of cracking and subsequent infection.
  • Manage underlying medical conditions and adhere to the treatment plan recommended by the diabetes care team.

Innovation and Advanced Care

For patients who develop hard-to-heal ulcers or who require advanced support, there are specialized treatments such as total contact casts, wound debridement (removal of dead tissue), growth factor therapies, and even biologic wound dressings. Adherence to off-loading protocols and working closely with healthcare providers is vital for maximizing healing and preventing recurrence.

The care of the diabetic foot is multifaceted, encompassing meticulous daily self-care, appropriate footwear, and regular professional monitoring. Prompt recognition and treatment of problems, combined with education and comprehensive management of diabetes and vascular health, are vital to reduce the risk of serious and costly complications, such as ulcers and amputation. Emphasizing proactive strategies and patient empowerment in diabetic foot care not only preserves limb health but also improves the overall well-being and quality of life for people living with diabetes

The six classic determinants of gait

The six classic determinants of gait are biomechanical features that optimize walking efficiency by minimizing the vertical and lateral displacement of the body’s center of gravity (COG) during locomotion. These determinants were first described by Saunders, Inman, and Eberhart in a 1953 seminal paper and represent movements and physiological strategies that contribute to a smooth, energy-efficient gait pattern. Essentially, the six determinants collectively reduce excessive motion that would otherwise increase energy expenditure and produce an awkward walking style sometimes described as a “compass gait,” where the legs move as rigid levers without the subtle joint actions that modulate motion.

The six determinants of gait are:

  1. Pelvic Rotation
    The pelvis rotates approximately 4 degrees forward on the side of the swinging leg and 4 degrees backward on the stance leg, totaling about 8 degrees of rotation in the transverse plane during walking. This rotation lengthens the stride and reduces the rise and fall of the body’s center of gravity by about 9.5 mm. Without pelvic rotation, the body would have to lift the center of gravity more for each step to cover the same distance, which would increase energy demands and vertical displacement. This rotation also contributes to smoother forward progression by advancing the hip of the swinging limb faster.
  2. Pelvic Tilt
    Pelvic tilt, sometimes called pelvic obliquity or pelvic listing, involves a slight drop of the pelvis on the side opposite to the stance leg during the stance phase. This lateral tilt decreases the height that the center of gravity must rise, thereby reducing vertical displacement and energy costs. The tilt lessens the vertical excursion by about an inch per stride, contributing to a more fluid gait pattern. Pelvic tilt also assists in maintaining balance by controlling side-to-side motion, ensuring the body’s weight is positioned over the supporting foot.
  3. Knee Flexion in Stance Phase
    After the heel strike (initial contact), the knee flexes slightly (about 15-20 degrees) to absorb shock and further lower the center of gravity during midstance. This knee flexion acts as a natural shock absorber, allowing the body to better handle ground reaction forces while smoothing the vertical trajectory of the center of mass. Without this knee flexion, the rise of the center of gravity would be more abrupt, causing a less efficient and more jarring gait.
  4. Foot and Ankle Mechanism
    The foot and ankle work together to modulate the vertical center of gravity. At heel strike, the ankle is dorsiflexed, and the center of rotation is elevated. As the foot moves toward flat on the ground, the ankle plantarflexes, lowering the center of rotation and allowing the body to descend smoothly. During push-off, the heel lifts, and the ankle plantarflexes again, raising the center of rotation and propelling the body forward. This complex motion helps minimize abrupt changes in vertical motion, enhances shock absorption, and contributes to smooth forward progression by acting like a rocker system
  5. Knee Motion in the Swing Phase
    The knee flexes during the swing phase to shorten the leg, allowing it to clear the ground more easily and reducing the upward displacement of the center of gravity. The knee then extends to prepare for the next heel strike. This mechanism allows for a smoother, more controlled leg swing and contributes to energy efficiency by preventing the body from moving up and down excessively. The swinging knee acts as a lever that helps conserve momentum while conserving energy
  6. Lateral Displacement of the Pelvis
    There is a controlled side-to-side shift of the pelvis over the stance leg to maintain balance and ensure the center of gravity remains within the base of support. This lateral pelvic displacement is necessary for stability, preventing the body from falling over the unsupported limb. The amount of sway is minimized by normal knee valgus and base of support width. This lateral shift not only aids in balance, but also reduces the amount of muscular effort needed to stabilize the body during single-limb support phases of gait.

Significance and Clinical Relevance

These six determinants present an integrated approach by which the body ensures walking is energy efficient, stable, and fluid. By minimizing the vertical and lateral displacement of the center of mass, the body reduces wasted energy that would otherwise be used to counteract excessive motion. The determinants provide a framework for clinicians to assess gait abnormalities and design interventions for pathological conditions that disrupt normal gait mechanics.

For example, a reduction in pelvic tilt or rotation due to weakness or stiffness may increase vertical displacement, causing a more tiring gait pattern. Impairments in knee flexion during stance can lead to a stiff-legged gait, increasing shock to joints and reducing walking efficiency. Similarly, disruptions in foot and ankle mechanisms, such as limited dorsiflexion or plantarflexion, can alter normal center of gravity modulation and lead to compensatory movements.

Understanding these determinants also allows clinicians and rehabilitation specialists to focus on restoring specific joint motions to improve gait quality, thereby reducing fatigue, enhancing balance, and preventing secondary musculoskeletal complications.

The six determinants of gait—pelvic rotation, pelvic tilt, knee flexion during stance, foot and ankle motion, knee motion during swing, and lateral pelvic displacement—collaboratively act to minimize vertical and lateral displacement of the center of gravity. This system reduces energy expenditure, increases walking smoothness, and maintains balance during gait. By orchestrating these movements, the human body achieves efficient locomotion and a graceful walking pattern. These principles continue to be foundational in gait analysis and rehabilitation, highlighting their enduring clinical and biomechanical importance.

The Calcaneal Squeeze Test

The Calcaneal Squeeze Test is a simple yet highly valuable physical examination maneuver in diagnosing heel pain, especially among children and adolescents. It plays a pivotal role in identifying specific pathologies such as Sever’s disease (calcaneal apophysitis) and calcaneal stress fractures. This essay explores the history, anatomy, procedure, clinical relevance, interpretation, differential diagnosis, limitations, and recent perspectives of the Calcaneal Squeeze Test in clinical practice.

Historical Context and Introduction

Heel pain in pediatric and adolescent populations can result from various causes; however, Sever’s disease and calcaneal stress fractures are among the most common. The Calcaneal Squeeze Test was designed as a quick, noninvasive clinical tool to help distinguish these entitities from other etiologies of heel pain. Although initially described for use in pediatrics, the test is also relevant for adults with suspected calcaneal injuries.

Anatomy and Pathophysiology

The calcaneus, or heel bone, is the largest tarsal bone, forming the foundation of the rear part of the foot. The posterior aspect contains the calcaneal apophysis—where the Achilles tendon inserts, and growth commonly occurs in children. In calcaneal apophysitis (Sever’s disease), inflammation and microtrauma at this growth plate lead to pain, especially in physically active children. Meanwhile, a calcaneal stress fracture arises from repeated overuse, often seen in runners and athletes.

Purpose and Indications

The primary clinical indication for the Calcaneal Squeeze Test is to assess the presence of pain or pathology within the calcaneus. It helps diagnose:

  • Sever’s disease (children/adolescents)
  • Calcaneal stress fractures (especially in athletes)
  • Less commonly, other pathologies (infection, tumor, bursitis, plantar fasciitis).

Test Procedure

The test is performed with the patient in a seated or supine position, foot relaxed. The examiner cups the posterior aspect of the patient’s heel using both hands—placing the thumb and fingers on the medial and lateral sides of the calcaneus. Gentle yet firm compression is applied medially and laterally:

  1. Patient sits or lies down, foot relaxed.
  2. Examiner uses thumb and fingers to grasp either side of the heel.
  3. Compression is applied to both sides simultaneously, focusing pressure directly over the growth plate or midbody of the calcaneus.
  4. The examiner observes and inquires about any pain responses during compression.

Positive vs. Negative Test

  • Positive Test: A positive result is indicated by pain that is localized to the compressed area. This suggests possible Sever’s disease in children or a calcaneal stress fracture in adults.
  • Negative Test: Absence of pain or discomfort points to a lower likelihood of these pathologies and prompts consideration of alternative diagnoses.

Differential Diagnosis

As heel pain can result from multiple causes, the Calcaneal Squeeze Test helps narrow the differential diagnosis:

  • Sever’s Disease: Pain specifically elicited during the squeeze, especially in physically active children.
  • Calcaneal Stress Fracture: Pain in adults/athletes, often associated with a history of overuse or trauma.
  • Plantar Fasciitis: Typically produces pain upon palpation of the plantar heel (not medial/lateral compression).
  • Heel Pad Atrophy/Bursitis: Pain localized to the fat pad or insertion, often discerned using a variation called the fat pad squeeze test.

Clinical Value and Interpretation

The test is valued for its simplicity and utility. In children with a positive squeeze test, Sever’s disease becomes strongly suspected, especially with corroborating clinical history (activity-related pain, recent growth spurt). In adults or adolescents, a positive result with a relevant history suggests a possible stress fracture.

The result must always be interpreted in the context of the full clinical picture. If pain is elicited elsewhere (plantar surface, achilles insertion), other diagnoses should be considered and further imaging (like X-rays or MRI) may be necessary to rule out complex or multilayered injuries.

Limitations

Despite its utility, the Calcaneal Squeeze Test has limitations:

  • It is not specific for one pathology alone; both Sever’s disease and stress fractures can yield similar positive findings.
  • It may not reliably distinguish between inflammatory, infectious, or neoplastic causes.
  • In early-stage disease, sensitivity may be reduced—patients may not always reproduce pain on examination.
  • Imaging may still be required for definitive diagnosis when clinical suspicion remains high despite a negative or equivocal test.

Advances and Recent Perspectives

Recent practice embraces the Calcaneal Squeeze Test as an initial assessment, supplemented by imaging where history and exam are inconsistent. The test’s gentle nature ensures safety, especially among children, and allows for repeated evaluation to track response to treatment. Newer research suggests pairing the squeeze test with other maneuvers (e.g., the fat pad squeeze test) for a more comprehensive evaluation of heel pain.

Clinical Example

Consider a 10-year-old soccer player presenting with bilateral heel pain, worsened after running and improved with rest. A positive result on the calcaneal squeeze test strongly supports a diagnosis of Sever’s disease, particularly when matched with age and activity history. Early identification allows for rest and load management, reducing recovery times and preventing chronic pain syndromes.

The Calcaneal Squeeze Test is an invaluable in-office examination technique that can streamline the diagnosis of heel pain—especially Sever’s disease in children and calcaneal stress fractures in active individuals. Its straightforward methodology, non-invasiveness, and diagnostic utility make it a staple in orthopedic, pediatric, and sports medicine settings. Proper application, combined with clinical judgment and selective imaging, optimizes patient outcomes in the evaluation of heel pain.

The cuboid notch on foot orthotics

The cuboid notch is a prominent specialized feature in foot orthotics design, aimed at providing targeted support to the lateral column of the foot, and, more specifically, to the cuboid bone itself. The use of the cuboid notch is both nuanced and significant, particularly when addressing complex biomechanical pathologies and optimizing functional movement in various patient populations.

Anatomy and Biomechanical Role

The cuboid bone serves as a static and rigid lateral element of the foot, conferring inherent stability to the lateral arch. Its strategic location, bridging the calcaneus and the metatarsals, makes it susceptible to mechanical stresses, subluxations, and dysfunctions, particularly in active individuals or those with planar foot deformities. When the cuboid becomes unstable or subluxed, conditions such as “cuboid syndrome” or “calcaneocuboid fault syndrome” may arise, with symptoms including lateral foot pain, swelling, and altered gait mechanics.

What is a Cuboid Notch?

A cuboid notch (sometimes called a cuboid raise, pad, elevation, or modification) is a more specific form of lateral column support in foot orthotics. It can be incorporated intrinsically into the orthotic shell during fabrication, or added extrinsically to the shell later using materials such as EVA, cork, or Poron. Traditionally, it was formed by shaving or scooping out plaster under the cuboid on the positive foot model, but modern computer-aided design systems (CAD) allow for elevation under the cuboid in millimetric precision.

Clinical Indications and Applications

The cuboid notch is primarily indicated when a clinician seeks to:

  • Support the cuboid to counteract plantar subluxation, resisting downward movement of the bone in cases of cuboid syndrome.
  • Provide lateral column stabilization, thus improving overall foot function and reducing lateral foot pain resulting from instability or subluxation.
  • Facilitate the medial movement of the center of pressure in midstance, leveraging the high gear propulsion concept.
  • Enhance pronatory moment at the subtalar and midtarsal joints, benefiting patients with excessive supination or lateral instability.youtube​
  • Elevate the inclination angle of the calcaneus, which is a modification sometimes referred to as the Feehery Modification.

Mechanisms and Effects

The cuboid notch imparts a directed upward force beneath the cuboid, resisting its tendency to subluxate or “drop” during dynamic activity. It plays a key role in redistributing forces across the foot’s lateral column, and altering the mechanical advantage of crucial tendons like the peroneus longus, which stabilizes the first ray. Additionally, it can help prevent the foot from sliding laterally off an orthotic, especially in instances where other features (e.g., medial skive) are incorporated to increase supinatory moments.

Intrinsic vs. Extrinsic Application

An intrinsic cuboid notch is part of the shell’s actual design, shaped into the orthotic at the time of fabrication and not easily modified post-production. On the other hand, an extrinsic notch or pad can be attached to the surface of the orthotic later and adjusted or removed as needed — providing flexibility for clinicians to test or fine-tune the effect through adhesive felt padding as a “treatment direction test”.

Evidence and Controversies

Despite its widespread clinical use, published research on the cuboid notch is limited, and there remains no strong consensus on its precise effectiveness or indications. Some clinicians report excellent clinical outcomes — pain reduction, improved stability — while others encounter adverse results, such as increased pain due to misplacement of the notch or pad. It has been suggested that moving the notch or pad medially under the cuboid (rather than too lateral) offers an inversion force to the bone, which may be more beneficial biomechanically, considering the cuboid both everts and plantarflexes as part of calcaneocuboid joint function.

Manufacturing and Prescription Considerations

Manufacturers accept prescriptions for cuboid notches in various specifications, often measured in millimeters, and can incorporate them either in custom or prefabricated orthotics. Clinicians who model foot casts through weightbearing or semi-weightbearing methods are more likely to use a cuboid notch, as this approach affects the lateral arch profile, often necessitating additional lateral support.

Related Modifications

There are several well-documented shell modifications related to the cuboid notch, including:

  • Feehery Modification: Extends the cuboid support posteriorly to include the lateral calcaneus.
  • Denton and Fettig Modifications: Variations in shape and placement for targeted effects.

Clinical Use: Cuboid Syndrome and Beyond

A cuboid notch can be particularly valuable in managing cuboid syndrome, lateral ankle instability, and peroneal tendon pathologies. By supporting the cuboid, the orthotic aids in restoring functional alignment, reducing pain, and possibly improving propulsion mechanics during gait.

Materials and Adjustability

A variety of materials can be used for cuboid notch modifications:

  • EVA (Ethylene-vinyl acetate): Commonly used for extrinsic pads due to ease of shaping and adjustment.
  • Cork, Poron: Other materials offering different densities and support characteristics.
  • Myolite: Sometimes used for offloading applications, providing cushioning and lateral stability.

Extrinsic cuboid pads are favored for initial trials and adjustments, given their removability and fine-tuning capability. If symptoms worsen, the cuboid pad can be repositioned or removed altogether.

Practical Clinical Approach

In practice, clinicians often employ adhesive felt pads as provisional tests to determine the therapeutic effect before committing to permanent orthotic modifications. This trial-and-error approach helps identify individuals who will benefit from targeted lateral column support without risking exacerbation of symptoms

The cuboid notch remains a versatile and important modification in foot orthotics, especially for lateral column stabilization, managing cuboid subluxation, and improving overall foot biomechanics. Its application requires thorough understanding of foot anatomy, pathology, and individual gait mechanics, as well as careful consideration during prescription and design. As more research emerges, clinicians may gain better insights into optimal placement and efficacy, ensuring improved outcomes for patients with complex lateral column problems.

Pros and Cons of Crocs Footwear for Foot Health

Crocs footwear has gained massive popularity around the globe, becoming a mainstay for casual comfort and even medical environments. While Crocs offer distinct advantages related to comfort, hygiene, and specific medical conditions, they also present unique risks when worn for extended periods or used outside of their intended contexts. This essay examines the pros and cons of Crocs footwear specifically in relation to foot health, integrating medical expert analysis, podiatrist opinions, and wearer experiences.

Benefits of Crocs Footwear

Comfort and Cushioning

One of the most prominent attractions of Crocs is their cushioned feel, thanks to their proprietary foam material known as Croslite™. This material adapts to the shape of the foot, providing shock absorption and reducing pressure on key areas such as the heel and ball of the foot. Individuals suffering from foot pain or fatigue, including those with plantar fasciitis or metatarsalgia, often report symptomatic relief when wearing Crocs. The light, cushioned effect makes each step feel gentler, which is particularly beneficial for people who spend long hours standing or walking.

Slip-Resistant and Protective

Many models of Crocs feature textured, slip-resistant soles. This design helps provide stability and reduce the risk of slipping on wet or slick surfaces. As a result, Crocs are a favorite in both medical settings and around the home, giving wearers increased confidence and safety, especially in environments prone to moisture.

Hygiene and Easy Maintenance

Unlike many shoes crafted from textiles or leather, Crocs are composed of non-porous foam. This makes them easy to clean, as dirt does not penetrate and odours aren’t absorbed. A simple rinse with water or disinfectant keeps them sanitary and fresh. This factor is especially important in settings like pools, beaches, locker rooms, and hospitals, as Crocs can help prevent the spread of fungi and bacteria that thrive in damp conditions.

Breathable and Lightweight Design

Crocs are notably lightweight, reducing overall foot fatigue. Their wide fit and ventilation holes promote airflow, helping to prevent sweat build-up and subsequent odours or skin irritation. For those seeking shoes that keep feet cool in warm climates or during physical activity, Crocs offer an effective solution.

Versatility and Affordability

Compared to many specialist orthopaedic shoes, Crocs present a relatively affordable means of accessing much of the same comfort and protection. Their multipurpose use is a significant appeal—a single pair can transition from hospital, to garden, to beach, without the need for frequent cleaning or changing shoes.

Support for Specific Foot Conditions

Many patients with plantar fasciitis, bunions, or other common foot ailments find Crocs help attenuate discomfort. The cushioned footbed and wide design cater to those who require extra toe-room or need to avoid compression and friction.

Drawbacks of Crocs Footwear

Lack of Proper Arch Support

While Crocs offer notable cushioning and some arch support, experts highlight that this support is often insufficient for prolonged use or for individuals with flat feet. Podiatrists warn that extended wear can put extra strain on the plantar fascia—the ligament supporting the arch—potentially leading to plantar fasciitis, Achilles tendinitis, bunions, and other foot disorders. Those who are flat-footed or prone to arch problems may be better served by footwear with structured support tailored to their anatomy.

Insufficient Heel Support

A critical limitation of standard Crocs models is their backless design. Without proper heel support or stabilization, wearers are at greater risk of heel pain, tendonitis, and instability. The need to grip with the toes to keep the shoe in place can exacerbate issues, resulting in discomfort, blisters, toe deformities, and balance problems. Running or participating in sports while wearing Crocs can dramatically increase the risk for sprains, trips, and falls.

Unsuitability for Extended Use

Despite their comfort, Crocs are generally not recommended for all-day, everyday wear. Extended use forces the feet and toes to work harder to maintain stability. Medical professionals advocate limiting Crocs use to short-term activities or appropriate environments—such as beaches, pools, or medical facilities—while opting for more supportive shoes during rigorous activity or lengthy walking.

Potential for Sweating and Skin Irritation

Although Crocs incorporate ventilation holes, their foam-plastic material is not as breathable as fabric or leather. This can cause excessive sweating, skin irritation, and odour, especially if worn without socks or for extended periods. Friction between foot and plastic may also lead to blisters and other skin issues in susceptible individuals.

Risk of Toe and Foot Deformities

The requirement to grip with the toes can introduce or worsen deformities over time, such as corns, calluses, hammer toes, and similar conditions. The wide, unsupportive design does not evenly distribute load or stabilize the foot during movement, contributing to biomechanical strain.

Limited Utility for Athletic Activities

Crocs are unsuitable for sports or high-impact activities. Their slip-resistant soles, backless structure, and overall design were meant for comfort and protection rather than agility or strenuous physical use. Attempting athletic activities in Crocs increases the risk of injury and is strongly discouraged by medical professionals.

Crocs and Special Populations

Crocs can be uniquely beneficial—or dangerous—for certain populations:

  • Children: Crocs may protect against minor impacts but do not stabilize the foot, raising risks for falls or injury during active play.
  • Older Adults: The slip-resistance may help prevent falls, but instability from the backless design could exacerbate balance problems.
  • Hospital Workers: Crocs offer hygiene and comfort in medical settings, but may lack support for long shifts.
  • People with Foot Conditions: Those with bunions, warts, or plantar fasciitis may benefit from the design, yet should use caution regarding duration and activity type

Conclusion

Crocs have established themselves as convenient, affordable, and comfortable footwear offering cushioned support, slip-resistance, and hygiene benefits. They are especially valuable for short-term use in moist or high-contamination environments, or for individuals requiring extra toe room and mild cushioning. However, their lack of robust arch and heel support, potential to exacerbate foot strain, and increased risk of skin issues mean Crocs are not a panacea for foot health. Medical professionals advocate using Crocs judiciously—embracing their strengths for appropriate settings while acknowledging and mitigating their weaknesses. For optimal foot health, most podiatrists recommend alternating Crocs with structurally supportive footwear, particularly for prolonged standing, rigorous activity, or individuals with pre-existing foot conditions.

Use of toe spacers to treat foot problems

Toe spacers, also referred to as toe separators, have emerged as a widely recognized tool in managing and treating various foot problems, ranging from minor discomfort to chronic and debilitating conditions such as bunions, hammertoes, plantar fasciitis, and poor foot alignment. Their simplicity conceals a growing base of clinical interest and anecdotal evidence suggesting that their consistent use can yield significant improvements in foot health and overall well-being for both athletes and non-athletes alike.

What are Toe Spacers?

Toe spacers are small devices, typically made from silicone, foam, or other flexible materials, designed to be placed between the toes. Their purpose is to promote the natural spread of the toes by gently separating them and encouraging a return to anatomical alignment—a shape where the foot is widest at the toes, as opposed to the narrower shapes imposed by modern footwear. This restoration is essential because a lifetime of wearing shoes with tapered toe boxes compresses the toes and disrupts healthy foot mechanics, leading to a range of problems including altered gait, restricted blood circulation, and muscular atrophy.

Mechanisms of Action

The functionality of toe spacers centers on their capacity to counteract the negative effects of ill-fitting footwear and sedentary lifestyles. By realigning the toes and redistributing forces more evenly across the foot, toe spacers can:

  • Increase circulation by minimizing constriction, promoting tissue regeneration, and aiding the healing process.
  • Enhance balance and stability by widening the base of support, particularly valuable for athletes and older adults at risk of falls.
  • Restore normal toe alignment, which is critical in preventing and rehabilitating conditions such as bunions, hammertoes, plantar fasciitis, and Morton’s neuroma.​
  • Improve muscle activation within the foot, which strengthens the arches and promotes functional stability.

Toe Spacers and Bunions

One of the most common uses of toe spacers is in the management of bunions, a painful bony protrusion at the base of the big toe. While toe spacers do not cure or reverse bunions, research and clinical reports indicate that they may alleviate symptoms, reduce pain and pressure, and possibly slow the progression by promoting better alignment of the big toe joint. Patients frequently report improved comfort when wearing toe spacers, particularly during physical activity such as walking, running, yoga, or weight training.

Toe Spacers and Plantar Fasciitis

Plantar fasciitis, characterized by inflammation of the tissue band on the sole of the foot, is another condition where toe spacers find relevance. Proper toe alignment facilitated by spacers decreases strain on the plantar fascia during weight-bearing activities, promoting better shock absorption and reducing the microtrauma that triggers pain and inflammation. Consistent use, especially in combination with appropriate footwear, allows patients to regain functional movement and accelerate recovery.

Preventing and Managing Hammertoes

Hammertoe is a deformity causing an abnormal bend in the middle joint of a toe, often exacerbated by narrow shoes and weakened foot muscles. Toe spacers help by gently stretching the small muscles and ligaments around the toes, encouraging flexibility and restoring anatomical position. Regular use prevents further crowding and may bring relief from pain and inconvenience for individuals affected by the condition.

Injury Prevention in Athletes

Toe spacers have gained traction in the athletic community for their capacity to optimize performance and minimize injury risk. Athletes subject their feet to repeated stress, which can lead to deformities, reduced blood flow, and muscular fatigue. Toe spacers, incorporated into training routines, offer several advantages:

  • Enhanced balance and proprioception (the sense of foot position and movement), providing greater control in dynamic activities.
  • Reduced risk of blisters, corns, and pressure points by distributing forces evenly and alleviating toe crowding.​
  • Increased muscle recovery rates due to improved blood circulation and oxygen delivery to the tissues.
  • Support for arch development, which is crucial for shock absorption and propulsion during movement.

Clinical Perspectives and Patient Experiences

Many podiatrists and physical therapists recommend toe spacers as part of a broader rehabilitation program for various foot and heel conditions. They are often introduced alongside exercises targeting toe mobility, stretches for the plantar fascia, and guidelines for transitioning into wider, flatter shoes that respect the natural foot shape. Patients commonly experience positive results, noting reductions in pain, improvements in walking ability, and restoration of function in daily life

Limitations and Considerations

While the benefits are notable, toe spacers are not a cure-all solution. Their efficacy is most pronounced when combined with other interventions such as physical therapy, corrective exercise, and appropriate footwear selection. Not all patients adapt instantly, and some may experience temporary discomfort, especially if the foot deformity is advanced or if spacers are used for extended periods without acclimation. It may be necessary to introduce the devices gradually or seek professional guidance to ensure proper fit and to avoid causing new problems. Toe spacers are generally most effective as a preventive or an adjunctive therapy, particularly in the early stages of foot deformity rather than as a standalone treatment for severe cases

Practical Application and Guidelines

For optimal results, toe spacers should be used consistently, preferably during periods of rest and light activity at first, before progressing to use during exercise or extended wear. Their benefits may be amplified when paired with barefoot walking, yoga, and strength exercises for the foot muscles. Ensuring appropriate fit and material choice is important to avoid irritation, and routine inspection of the feet for signs of pressure or discomfort is recommended.​

Future Directions and Research

Recent studies hint at further applications of toe spacers, especially in improving overall posture, alleviating hip and knee pain caused by poor foot mechanics, and possibly decreasing the risk of chronic musculoskeletal problems down the kinetic chain. More rigorous, long-term studies are needed to fully establish their role within the spectrum of conservative foot care. Their accessibility and low cost, however, make them a promising option for individuals seeking non-invasive methods to improve foot health.

Toe spacers have carved out a substantive role in the treatment and prevention of a wide range of foot problems, particularly those stemming from poor toe alignment and muscular dysfunction. Their ability to restore the foot’s natural shape, enhance circulation, and reinforce balance and stability make them valuable for both everyday users and high-performance athletes. When implemented thoughtfully—preferably alongside physical therapy, corrective exercises, and proper footwear—toe spacers can play an essential part in rehabilitating the feet, improving mobility, reducing pain, and promoting lifelong musculoskeletal health.

What are COVID toes?

COVID toes is a rare but recognized symptom associated with COVID-19 infection, characterized by swollen, discolored toes that often appear red, purple, or purplish-brown. This condition causes inflammation resembling chilblains, presenting as painful, itchy, or numb toes and sometimes fingers. While the exact cause of COVID toes remains uncertain, research points to it being an immune system response to the SARS-CoV-2 virus, potentially involving inflammation of small blood vessels in the extremities. COVID toes typically last one to two weeks and usually resolve without specific treatment, although in severe cases medical intervention may be necessary.

What Are COVID Toes?

COVID toes manifest as skin changes primarily on the toes but occasionally on the fingers, appearing as red or purplish discolorations, swelling, and sometimes blisters or raised bumps. The toes may feel painful, itchy, or numb, and the condition resembles chilblains — an inflammation of small blood vessels triggered by cold exposure but occurring here as a pseudo-chilblain phenomenon linked to COVID-19 infection. Such discoloration can appear as bright red initially then turn purple or purplish-brown, impacting both light and dark skin tones differently, with dark skin showing brownish-purple spots or swelling.

Causes and Mechanisms

The precise etiology of COVID toes is still debated in the medical community, but several contributing factors have been proposed:

  • Immune Response: One leading hypothesis is that COVID toes occur as a result of the body’s immune response to the virus, where inflammation affects small blood vessels in the toes and feet, causing swelling and discoloration. This immune-mediated inflammation may be the body’s antiviral response.
  • Vascular Effects: SARS-CoV-2 may directly or indirectly affect blood vessels, contributing to these cutaneous vascular changes seen as COVID toes.
  • Similarity to Chilblains: The condition resembles chilblains, which typically arise from cold exposure causing painful inflammation in extremities. COVID toes represent a “chilblain-like” lesion but seemingly triggered without cold exposure.
  • Underlying Health Conditions: Individuals with poorer circulation, such as in diabetes or peripheral artery disease, or those immobilized during hospital stays, may be more susceptible to developing COVID toes.

Symptoms and Duration

Typical symptoms of COVID toes include:

  • Red or purple discoloration on one or more toes or sometimes fingers
  • Swelling and sometimes puffiness of the affected digits
  • Itchiness, burning sensation, pain, or numbness
  • Raised bumps, patches of rough skin, or blisters in some cases
  • Sometimes pus under the skin (rare)

Most people experience resolution of these symptoms within 1 to 2 weeks, although persistent or recurrent cases lasting months have been reported.

Diagnosis

Diagnosis largely depends on clinical examination and history of recent or concurrent COVID-19 infection. Though some patients may have tested negative for COVID-19, the diagnosis can be suspected based on characteristic appearance and timing during the pandemic waves.

Treatment and Management

There is no specific antiviral treatment for COVID toes since it is mostly a self-limited inflammatory response. Management focuses on symptomatic relief and monitoring for complications:

  • Pain relief with over-the-counter medications like ibuprofen or acetaminophen
  • Antihistamines for itching
  • Topical corticosteroids (such as hydrocortisone cream) to reduce inflammation
  • Elevating the foot and applying cold compresses to help reduce swelling
  • Wearing loose, comfortable footwear to avoid further irritation
  • In severe or persistent cases, medical consultation is recommended; some treatments like cilostazol have been reported to help by relaxing blood vessels.

If underlying conditions such as diabetes or peripheral artery disease are present, they should be managed appropriately to prevent worsening of symptoms.

Prognosis and Concerns

COVID toes are generally benign and not life-threatening, but they may signal an active immune reaction or potential vascular involvement. They can cause discomfort and impact quality of life temporarily. Importantly, the presence of COVID toes should prompt consideration of COVID-19 infection, even if respiratory symptoms are absent or mild. Patients experiencing unusual skin changes should seek medical advice to rule out other causes and receive appropriate care.

Summary

COVID toes describe a distinctive, chilblain-like skin condition affecting the toes (and sometimes fingers) linked to COVID-19 infection. It involves swelling, discoloration, and sometimes pain or itchiness, caused primarily by the body’s immune response to the virus leading to vascular inflammation. Mostly seen in children, teens, and young adults, the condition usually resolves on its own within a couple of weeks with supportive care. Awareness of COVID toes can aid in early recognition of COVID-19 cases and guide symptomatic treatment and supportive management.

This understanding is continuously evolving with ongoing research into the dermatologic and vascular effects of the SARS-CoV-2 virus.

Do corns on the feet have ‘roots’?

Corns on the feet, contrary to popular belief, do not have roots. The perception that corns possess roots from which they regrow is a prevalent myth, but medical and podiatric evidence makes it clear that this is a misunderstanding of how corns form and recur. This essay explores the nature of corns, clarifies why they reappear after removal, explains the underlying mechanism behind their development, and highlights best practices for long-term management.

Understanding What a Corn Is

A corn is a localized thickening of the skin that develops in response to excessive and repetitive pressure or friction, typically on the toes or the soles of the feet. Corns are essentially protective mechanisms, where the skin densifies in defense against localized trauma. They are commonly seen in people who wear ill-fitting shoes, have foot deformities such as hammertoes or bunions, or have any structural abnormality that leads to abnormal pressure points.

Medically, there are several types of corns, with the most familiar being hard corns (found on the tops and sides of toes or on the balls of the feet) and soft corns (typically developing between the toes in moist areas). Both types share a core characteristic: a central, conical area of dense, keratinized skin often described as a “core.” This core, though, is not a root but rather a localized response to pressure.

The Myth of Corn Roots

The analogy of a corn having a “root,” like a plant, has persisted largely because of how a corn looks and feels. When corns are pared down, especially by a podiatrist, the central core may appear pointed or deep, but it is not a living “root” embedded in the tissue. Instead, it is simply the point of highest pressure and thickest skin. As the corn is shaped like an upside-down cone, the narrowest area—the “core”—points inward to the source of pressure, generally a bone or a structural protrusion, and broadens outward toward the skin’s surface

Why Corns Keep Coming Back

Corns tend to recur if the underlying cause—repetitive pressure or friction—remains unaddressed. Removal procedures, whether self-administered or done by a professional, typically eliminate the hard, painful lesion and relieve symptoms temporarily. However, because there is no genuine root that must be extracted, removing the “core” of the corn without addressing external or internal pressures inevitably leads to recurrence.

  • If the shoe or mechanical issue causing excessive pressure is not remedied, the skin will once again thicken in self-defense at the same spot, causing the corn to “grow back”.
  • Typical factors often responsible for persistent or recurring corns include poor shoe fit, biomechanics, foot deformities, and occupational or activity-related repetitive pressure.

Debunking the “Root” Theory

Medical literature and foot specialist consensus are unequivocal: corns do not grow from a root, and removal of a so-called “root” does not prevent their return. The notion that leaving behind part of the corn leads to regrowth, as might occur with warts if viral tissue remains, is untrue. Even meticulous and thorough removal of all hardened material will not suffice if the pressure stimulus remains.

This misunderstanding is also fueled by how, even after meticulous removal, corns may reappear in precisely the same spot. This recurrence is due to ongoing pressure, not due to biological regrowth from rootlike tissue. Podiatrists clarify that pressure comes from anatomical factors (such as prominent joints or bones) or mechanical ones (tight shoes or repetitive motions). Thus, without eliminating or modifying the underlying source of pressure, the corn will almost always return.

The Corn’s Core Versus a Root

Some confusion arises because corns feature a central core of dense keratin that can seem rootlike. In reality, this core points toward the source of pressure beneath the skin and is made of dead, compacted skin cells. It penetrates slightly more deeply into the skin than surrounding tissue but stops short of any true “root” structure. Surgical or superficial removal of this core, while relieving discomfort, does not address the cause.​

Prevention: Addressing the Root Cause

Since corns redevelop if the pressure or friction persists, the most effective way to prevent recurrence is to target these underlying mechanical forces:

  • Wear properly fitting footwear with adequate toe space and cushioning.
  • Use orthotic devices or custom insoles if structural foot issues are present.​
  • Treat or accommodate foot deformities such as hammer toes, bunions, or bone spurs.
  • Reduce repetitive activities that stress the same area if possible.

In some cases, surgical correction of the responsible bony prominence may be recommended for chronic or severe corns that fail conservative measures. Simple behavioral changes, like trimming toenails correctly and choosing shoes that minimize pressure, can go a long way in breaking the cycle of recurrence.

Medical Management of Corns

For most individuals, a podiatrist can remove the thickened skin, and provide advice or devices to offload pressure points, along with skin care guidance. Drug store remedies, such as salicylic acid pads, can break down thickened skin, but should be used with care, especially in people with diabetes or poor circulation. Additionally, protective pads and regular moisturization help reduce symptoms and recurrence risk.

In sum, corns on the feet do not have roots, and their regrowth is not due to missed “root” tissue but to unchanged pressure or friction at the site. The myth of corns having roots stems from the visual appearance of their core and their persistence after removal. Effective management requires a focus on footwear choices, structural foot health, and addressing biomechanical issues, rather than solely on the regular removal of the dead skin. With a holistic preventive approach, corns can be successfully managed and prevented from returning.

Concussion and the Lower Limb

Concussion significantly increases the risk of subsequent injury in the lower limb, particularly among athletes returning to play after such an event. This essay explores the epidemiological evidence, biomechanical and neurological mechanisms, timeframes of elevated risk, and implications for injury prevention.

Epidemiological Evidence

Recent studies consistently show a heightened incidence of lower limb injury following concussion, with risks elevated both among amateur and professional athletes. For example, collegiate athletes demonstrated a 58% greater risk of lower extremity musculoskeletal injury post-concussion. This added risk may remain for months up to a year, especially pronounced within the first 90 days after return to play. A large-scale analysis of soldiers found a 38–45% greater hazard for lower extremity injury among those who had sustained concussion compared with matched non-concussed controls

The consistency of increased risk across populations—high school, collegiate, professional athletes, and military personnel—supports the generalizability of this association. Additionally, a history of multiple concussions is correlated with an even higher risk of future musculoskeletal injuries in the lower limb.

Neuromechanical Explanations

The mechanism underlying this increased risk appears to be related to persistent neuromuscular control deficits following concussion. While standard concussion protocols focus on symptom resolution, individuals may continue to experience subtle motor abnormalities despite feeling symptom-free. Studies examining post-concussion athletes found altered movement patterns, such as greater knee valgus and increased knee internal rotation during jump-cut maneuvers—both implicated in higher injury risk, such as ACL tears

Changes in lower limb stiffness during landing, delayed muscle activation, and disruptions in motor planning are commonly observed in post-concussion athletes. These neuromuscular disturbances may result from lingering impairment of central nervous system processing, affecting joint position sense, balance, and coordination.

Biomechanical Changes and Injury Risk

Biomechanical studies highlight that many post-concussion athletes display atypical gait and landing mechanics, which can predispose them to non-contact injuries such as sprains, strains, and tears. For example, increased dynamic knee valgus is strongly associated with non-contact ACL injuries. Inadequate neuromuscular control may undermine the protective mechanism during rapid direction changes or load absorption, commonly required in many sports.

These alterations are not necessarily detected by routine return-to-play evaluations, which may depend heavily on subjective symptom reporting and basic balance testing. Consequently, some athletes are cleared for play while still harboring deficits that increase lower limb injury risk.

Duration of Increased Risk

While the pattern is clear, the duration of elevated injury risk is still debated. Some research indicates risk persists for up to one year, with the highest vulnerability within the first three months following concussion. However, as neuromuscular function gradually improves, this heightened risk may diminish. Sub-analysis indicates college athletes are less likely to experience increased lower extremity injury risk at one year post-concussion compared to immediately after return to play.

Such findings have critical implications for post-concussion management in athletes. Continuous evaluation and gradual reintroduction to full activity may help minimize the window of heightened risk.

Mechanistic Theories

Several mechanistic theories seek to explain the link between concussion and lower limb injury risk:

  • Central Sensory Deficits: Concussive injuries can disrupt integration of sensory inputs needed for coordinated movement, balance, and agility, increasing susceptibility to missteps or awkward landings.
  • Motor Planning Disruption: Subtle deficits in executive motor control can delay muscle activation or alter movement strategies during sport-specific tasks.
  • Delayed Reaction Time: Even after apparent clinical recovery, cognitive and motor reaction times may remain slowed, hampering athletic responses to unpredictable situations and thus increasing injury risk.
  • Psychological Factors: Anxiety about re-injury or decreased confidence in movement ability may also alter biomechanics in the lower limb.
  • Insufficient Rehabilitation: Rapid clearance and return to play without comprehensive neuromuscular and functional assessments may leave athletes vulnerable.

Implications for Clinical Management

Given the evidence, clinicians should recognize that symptom resolution does not necessarily equate to full physiological recovery post-concussion. Consideration of underlying neuromuscular deficits is essential. Standard concussion tests may miss subtle deficits in coordination, proprioception, and muscle firing patterns crucial for safe athletic movement.

Actual injury rates after concussion suggest the need for more robust clearance protocols, possibly including validated neuromuscular testing, gait and movement analysis, and continued monitoring post-return to play. Moreover, periodic re-evaluation may catch lingering deficits that predispose athletes to injury.

Future Directions

Ongoing research should further explore:

  • Quantifying the time course of motor recovery and injury risk after concussion.
  • Expanding biomechanical and neuromuscular assessment protocols for return-to-play decision-making
  • Developing specific rehabilitation programs aimed at restoring neuromuscular control and reducing lower extremity injury risk.
  • Investigating individualized recovery paths, given variation in concussion effects, and tailoring intervention strategies accordingly.

Concussion acts as an important risk factor for subsequent lower limb injury, particularly in the months immediately following return to play. Elevated risk may be attributed to lingering neuromuscular and biomechanical deficits, not always detectable via standard clinical evaluation. Integrating neuromuscular assessment and targeted rehabilitation into concussion protocols—and recognizing the need for extended vigilance—can help reduce injury rates and safeguard athlete health. The observed association underscores the importance of holistic concussion management beyond symptom resolution, highlighting a new facet of injury prevention in sports medicine
