Anterior Ankle Impingement

Mobility of the ankle joint play a vital role in most of our daily activities such as walking, using the stairs, transitioning from sitting to standing and crouching down. Several factors can contribute to a reduction in the range of movement of the ankle joint; in most cases, ankle mobility exercises can rectify these issues.
The most common reason for reduced mobility in the ankle joint is the result of a tight calf muscle. The calf muscle is a large muscle that sits on the back of the shin that helps to plantarflex the foot. If it is tight, it restricts the ankle’s ability to dorsiflex.
Other causes of reduced ankle mobility include scar tissue formation at the front of the ankle, leading to anterior ankle impingement. An impingement can cause a pinch at the front of the ankle when moving the knee over the toes.
A common complaint is that restricted ankle mobility prevents people from doing a squat. While ankle mobility exercises can help, another solution is to place a heel raise under your heel or wear a high drop trainer when doing a squat which resolves the issue in the short term for most instances.
Foam rolling the calf muscle can increase blood flow to the area, improving the flexibility of the tissue.
The Gastrocnemius muscle is part of the calf muscle group, playing a vital role in the push off phase of the gait cycle. It the Gastrocnemius muscle becomes too tight it can restrict your stride length.
The Soleus muscle is part of the calf muscle group, making up 2/3 of the calf muscle. It plays a vital role in the stability of the foot and ankle. When tight, the Soleus muscle can severely limit the ability to squat or crouch down.
The Anterior Tibialis Muscles sits on the front of the shin, attaching to the top of the foot. The Anterior Tibialis helps to lift the foot when walking and tightness in this muscle can restrict ankle mobility, especially moving into plantarflexion. People notice this most when they are trying to sit back onto their heels.
The Plantar Fascia sits on the underside of the foot, connecting the heel to the forefoot. It plays a vital role in the windlass mechanism that facilitates a normal walking and running gait.
