THE IMPORTANCE OF REHABILITATION AFTER ANKLE SPRAINS IN CHRONIC ANKLE INSTABILITY PREVENTION

Abstract

Chronic ankle instability occurs in 20–40% of patients with a history of ankle sprain and as late as 6.5 years following the injury. The main causes are considered to be lateral ankle ligament laxity, peroneal muscle weakness and ankle proprioceptive deficits. These sequelae are usually met if the rehabilitation program was not correctly applied (both length and also quality execution). Limiting the apparition of chronic ankle instability by following a physical therapy program correctly established, in cases where there are no other chronic ankle pain and/or chronic ankle instability causes (like coexistent fractures, arthropathy, midfoot or subtalar sprains, subtalar instability, ankle impingement syndrome, sinus tarsi syndrome, peroneal tendinopathy, reflex sympathetic dystrophy, ankle and foot arthrosis). The treatment depends on the injury mechanism (the most typical is inversion) and on grade of the sprain (mild, moderate, severe) and includes three phases (acute, subacute and the rehabilitative phase). The physical therapy program begins during the subacute phase and is continued during the rehabilitative phase, which can last up to three weeks. Surgical reconstruction of the lateral ankle ligaments is rarely necessary. It is important to point out to our patients the fact that returning to daily activities (such as work and sports) prior to adequate healing and rehabilitation may result in chronic pain and/or functional or mechanical instability.
