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 ) .
Six weeks of balance training improves sensorimotor function in individuals with chronic ankle instability.
STUDY DESIGN Prospect i ve cohort study . OBJECTIVE To assess the effect of 6 weeks of balance training on sensorimotor measures previously found to be deficient in participants with chronic ankle instability ( CAI ) . BACKGROUND CAI is the tendency toward repeated ankle sprains and recurring symptoms , occurring in 40 % to 70 % of individuals who have previously sustained a lateral ankle sprain . Recent studies have found deficits in sensorimotor measures in individuals with CAI . As balance training is a common component of ankle rehabilitation , underst and ing its effect on the sensorimotorsystem in individuals with CAI may enable us to optimize protocol s to better utilize this rehabilitation method . METHODS Twelve participants with CAI and 9 healthy volunteers participated . Independent variables were group ( CAI , control ) and time ( pretraining , posttraining ) . Participants with CAI who completed a 6-week balance training program and healthy controls who did not get any training were pretested and posttested at the beginning and at the end of 6 weeks . RESULTS The individuals in the CAI group who performed balance training demonstrated better performance than control participants on baseline adjusted posttraining measures of dynamic balance in the anterior medial ( P = .021 ) , medial ( P = .048 ) , and posterior medial directions ( P = .030 ) ; motoneuron pool excitability Hmax/Mmax ratio ( P = .044 ) and single-limb presynaptic inhibition ( P = .012 ) ; and joint position sense inversion variable error ( P = .017 ) . It may be of note that no systematic differences were detected for static balance or plantar flexion joint position sense tasks . CONCLUSIONS After 6 weeks of balance training , individuals with CAI demonstrated enhanced dynamic balance , inversion joint position sense , and changes in motoneuron pool excitability compared to healthy controls who did not train . LEVEL OF EVIDENCE Therapy , level 2b
