Conclusions The main findings from this systematic review were balance training provided the most consistent improvements in self-reported function for patients with CAI
Objective To identify which therapeutic intervention may be most effective for improving self-reported function in patients with chronic ankle instability ( CAI ) .
Persistent Disability Associated with Ankle Sprains: A Prospective Examination of an Athletic Population
The purpose of this study was to examine a young athletic population to up date the data regarding epidemiology and disability associated with ankle injuries . At the United States Military Academy , all cadets presenting with ankle injuries during a 2-month period were included in this prospect i ve observational study . The initial evaluation included an extensive question naire , physical examination , and radiographs . Ankle sprain treatment included a supervised rehabilitation program . Subjects were reevaluated at 6 weeks and 6 months with subjective  assessment , physical  examination  , and functional testing . The mean age for all subjects was 20 years ( range , 17–24 years ) . There were 104 ankle injuries accounting for 23 % of all injuries seen . There were 96 sprains , 7 fractures , and 1 contusion . Of the 96 sprains , 4 were predominately medial injuries , 76 were lateral , and 16 were syndesmosis sprains . Ninety-five percent had returned to sports activities by 6 weeks ; however , 55 % of these subjects reported loss of function or presence of intermittent pain , and 23 % had a decrement of > 20 % in the lateral hop test when compared with the uninjured side . At 6 months , all subjects had returned to full activity ; however , 40 % reported residual symptoms and 2.5 % had a decrement of > 20 % on the lateral hop test . Neither previous injury nor ligament laxity was predictive of chronic symptomatology . Furthermore , chronic dysfunction could not be predicted by the grade of sprain ( grade I vs. II ) . The factor most predictive of residual symptoms was a syndesmosis sprain , regardless of grade . Syndesmosis sprains were most prevalent in collision sports . This study demonstrates that even though our knowledge and underst and ing of ankle sprains and rehabilitation of these injuries have progressed in the last 20 years , chronic ankle dysfunction continues to be a prevalent problem . The early return to sports occurs after almost every ankle sprain ; however , dysfunction persists in 40 % of patients for as long as 6 months after injury . Syndesmosis sprains are more common than previously thought , and this confirms that syndesmosis sprains are associated with prolonged disability
