Abstract

Inversion ankle sprains are common and are caused by sudden inversion stresses during weight-bearing movement which causes the foot to roll under and inward.1 Ankle sprains result in tearing or stretching of ligaments and muscles, which reduces ankle stability.2 After a single ankle sprain, up to 80% of people suffer repeated sprains, which often develop into chronic ankle instability (CAI).3 Research has shown CAI patients often exhibit delayed lower leg muscle reaction time and restricted dorsiflexion range of motion (DROM).2
