Introduction to the Foot and Ankle
Human movement is an intricate orchestration that encompasses sensory inputs, neuromuscular control mechanisms, and biomechanical principles for stabilization. At the heart of every closed-chain kinetic activity lies the foundational interaction between the foot and the ground, serving as the primary platform for establishing a base of support. This point of contact is crucial, as it facilitates the transmission of forces between the body and the ground, allowing for movement and locomotion. With each step, the foot absorbs and distributes a substantial amount of repetitive stress, manifested through ground reaction forces, which highlights the resilience and adaptability required from this complex structure.
The Regional Interdependence (RI) model underscores the notion that the human body operates as a cohesive unit, where each segment is interlinked, forming an integrated kinetic chain. According to Rath et al. (2016) and Riskowski et al. (2013), compensations or dysfunctions in one part of the body can precipitate related impairments elsewhere, establishing a domino effect of biomechanical inefficiencies. This concept holds particular significance for the foot and ankle complex, as dysfunctions here can have profound implications on the overall mechanics and motion of the lower extremity.
This chapter delves into the essential functional anatomy of the foot and ankle, examining its pivotal role in body movement and its dynamic interplay with other bodily regions. Furthermore, it elaborates on how disturbances in the foot and ankle’s normal function can influence the entire lower limb’s biomechanics. To address these challenges, we will explore targeted strategies designed to correct foot and ankle movement impairments. These interventions aim not only to restore proper function and mitigate pain but also to enhance the overall efficiency and harmony of human movement, emphasizing the critical nature of maintaining foot and ankle health for optimal biomechanical performance.
Foot and Ankle Assessment Results
Performing assessments of the lower extremities without footwear can provide a better understanding of how the foot and ankle complex function in their natural state. However, some clients may prefer to be assessed while wearing their footwear to see how their movement patterns are influenced by their shoes. In some cases, facilities may also have rules prohibiting barefoot testing.
To identify movement impairments, an integrated assessment process called the CES Assessment Flow is used. This process includes static posture, movement, and mobility assessments. By using this process, a Corrective Exercise Specialist can identify any mobility restrictions, muscle imbalances, or faulty movement patterns. Once these impairments have been identified, a corrective exercise strategy can be developed to address them.

Common Issues with the Foot and Ankle
Plantar Fasciitis
Plantar Fasciitis is a foot condition where the plantar fascia, a thick tissue that connects the heel bone to the toes, becomes inflamed. This condition causes sharp pain, especially during the first steps in the morning. The pain usually reduces as you move around but can return after long periods of standing or sitting.
Plantar fasciitis is a common cause of heel pain, and around 10% of people experience it at some point in their lives. The condition is most common in people aged between 40 and 60, and it’s more prevalent in runners, overweight individuals, and those who wear shoes without adequate support.
Activities that put a lot of stress on the heel, such as long-distance running, ballet dancing, and aerobic dance, increase the risk of developing plantar fasciitis. Occupations that require standing for long periods, such as factory workers, teachers, and waiters, also increase the risk.
The treatment for plantar fasciitis involves rest, ice, over-the-counter pain relievers, and physical therapy. Stretching and strengthening exercises can be particularly beneficial. More severe cases may require orthotic devices, steroid injections, or even surgery as a last resort. Most patients respond well to conservative treatment measures within several months, and early intervention is key to preventing chronic heel pain and maintaining mobility and quality of life.
Achilles Tendinopathy
Achilles Tendinopathy is a condition that affects the Achilles tendon, which is the band of tissue that connects the calf muscles to the heel bone. The condition is characterized by pain, swelling, and reduced function of the tendon. It is common among athletes, especially runners, and individuals who engage in activities that involve sudden increases in intensity or duration of exercise.
Approximately 9% of recreational runners and up to 5% of professional athletes are affected by this condition, and it is also prevalent among non-active individuals, especially those in their middle ages. Men are slightly more at risk than women, and it is most common in people between the ages of 30 and 50.
Several factors can increase the risk of developing Achilles Tendinopathy, such as sudden increases in physical activity, improper footwear, training on uneven surfaces, obesity, high blood pressure, and diabetes. Anatomical factors, such as flat feet or an abnormal walking pattern, can also contribute to the strain on the Achilles tendon.
The primary goal of treating Achilles Tendinopathy is to alleviate pain and restore normal tendon function. Initial management often involves rest, ice, and over-the-counter pain relief medications. Physical therapy is also an important part of the treatment plan, with exercises aimed at stretching and strengthening the calf muscles to reduce stress on the tendon. In more persistent cases, treatments may include orthotic devices, extracorporeal shock wave therapy, or platelet-rich plasma injections. Surgery is only considered when conservative treatments have failed to provide relief.
The prognosis for individuals with Achilles Tendinopathy is generally good, with most responding well to conservative treatment within three to six months. Early diagnosis and adherence to a structured rehabilitation program are crucial for a successful recovery. Preventive measures, such as gradual training increases and proper footwear, are essential in reducing the risk of Achilles Tendinopathy.
Medial Tibial Stress Syndrome
Medial Tibial Stress Syndrome (MTSS), commonly known as shin splints, is a condition that causes pain along the inner edge of the shinbone (tibia). This pain is due to inflammation of the muscles, tendons, and bone tissue around the tibia. It is usually caused by repetitive stress on the shinbone and the tissues attaching the shinbone to the surrounding muscles. MTSS is a common issue among runners, athletes, and military recruits, often resulting from overuse or a sudden increase in physical activity.
The incidence of MTSS varies widely but is especially common in activities that involve extensive running or jumping. Studies have shown that MTSS accounts for 13-17% of all running-related injuries and up to 35% of injuries among military recruits due to their rigorous physical training. The condition is more frequently observed in female athletes, potentially due to factors such as lower bone density and differences in lower limb alignment.
Risk factors for developing MTSS include a sudden increase in exercise intensity or duration, improper running techniques, inadequate footwear, and running on hard or uneven surfaces. Additionally, individuals with flat feet or abnormal arches are at a higher risk due to the increased stress on the shinbone and surrounding tissues.
The primary focus of treatment for MTSS is rest and reducing inflammation. This may include icing the affected area, using over-the-counter pain relievers, and modifying activity levels to avoid pain-inducing exercises. Physical therapy can be beneficial, emphasizing stretching and strengthening exercises for the muscles around the shinbone. In some cases, orthotic devices or corrective footwear might be recommended to address underlying biomechanical issues.
The prognosis for individuals with MTSS is generally good, with most patients experiencing significant improvement with conservative treatment within several weeks. Prevention strategies, such as gradual progression in exercise intensity, proper footwear, and attention to running form, are crucial for minimizing the risk of developing shin splints. Early intervention and adherence to a comprehensive treatment plan can help individuals return to their activities without long-term complications.
Ankle Sprains and Chronic Instability
Ankle sprains and chronic instability are common issues that affect both athletic and general populations. An ankle sprain occurs when the ligaments that support the ankle stretch beyond their limits or tear, leading to pain, swelling, and limited range of motion. Chronic instability is a condition where the ankle becomes repeatedly sprained or feels “wobbly” during physical activities, usually due to incomplete healing or rehabilitation from previous sprains.
Ankle sprains are one of the most common musculoskeletal injuries, with approximately 2 million cases occurring annually in the United States alone. They account for 20-30% of all sports injuries, highlighting their prevalence among athletes. However, they can also occur during daily activities such as walking on uneven surfaces or taking awkward steps. About 30-40% of individuals with an acute ankle sprain develop chronic symptoms, indicating the significance of the concern.
Risk factors for ankle sprains include previous ankle injuries, inadequate strength or flexibility in the ankle and surrounding muscles, engaging in sports or activities that involve sudden direction changes, running on uneven surfaces, or jumping. Factors contributing to chronic instability include incomplete rehabilitation, early return to activity post-injury, and recurrent injury.
The R.I.C.E. method (Rest, Ice, Compression, Elevation) is the standard treatment for acute ankle sprains, followed by exercises to strengthen the ankle, improve flexibility, and proprioception. Physical therapy that focuses on balance and proprioceptive exercises is crucial for chronic instability. In some cases, bracing or surgery may be necessary to repair or reinforce the damaged ligaments.
The prognosis for recovery from an ankle sprain is generally good, provided that proper treatment and rehabilitation are followed. However, preventing recurrent sprains and developing chronic instability requires a comprehensive approach, including strength training, proprioceptive exercises, and orthotic support. Early and appropriate management of ankle sprains is essential to reduce the risk of chronic issues and ensure a return to full functional activity.
