Ankle sprains are extremely common and generally occur when someone ‘rolls’ on their ankle damaging ligaments of the region. Most commonly sprains occur on the lateral side of the ankle (the outside region). Ankle sprains range in severity from a simple strain to a complete tear of the ligament. Although the majority of ankle sprains resolve quickly, in some cases pain and disability can persist for months due to problems such as synovitis (joint inflammation) which can develop if return to full weight-bearing after a sprain is too early or has been forced.
Functional instability of the ankle can occur with repeated ankle sprain or if the ankle doesn’t heal adequately after a bad sprain. This can be due to a combination of the ligaments being stretched out and muscles around the joint failing to support the joint. Poor proprioception (our unconscious awareness of body movement and position) is a common underlying cause of injury to the ankle. Little sensors / receptors built into the tissues of our body (joints, muscles, and ligaments) detect movement and send information about its direction and speed to our brain which in turn uses this information to plan and coordinate movement. Injury to tissues with these built in receptors mean that the brain has less information to work on and fails to activate muscles when appropriate, for example to ‘right’ the ankle when it is about to ‘roll’. Other common ankle injuries include bony and soft tissue impingement syndromes, fractures of the tibia / fibula, and tendon problems such as tibialis posterior tendinosis.
Treatment of most ankle problems involves physiotherapy including proprioception exercises to ‘retrain’ this pathway from the receptors to the brain and manual therapy to mobilise restrictions in range of movement where appropriate. Other treatment techniques include electrotherapeutic modalities and taping to correct excessive pronation (excessive inward rolling of the foot). The focus is always on the use of specific exercises to restore strength in relevant muscles, proprioception improvement and elimination of any biomechanical dysfunctions identified.
