Muscle Strength and Balance Training in subjects with Lateral Ankle Ligament Injury of Athletes

摘要

Balance training has been shown to be effective in preventing ankle sprainrecurrences in subjects with Lateral Ankle injury (LAI) but the biomechanical and/orneurophysiological pathways underlying the clinical outcomes are still unknown. This study wasconducted to determine if a 12-week balance training intervention can alter the mechanicalcharacteristics in ankles with LAI.Methods: fifty-two recreationally active subjects with LAI were randomized to 4 group (A, B, C, D) Group A control group (n=13) Group B BOSU Exercise training (n=13) Group C Neuromuscular training (n=13) Group D Combined intervention of B+C (n=13) Subjects in the intervention group were trained on the affected limb with static and dynamiccomponents using a training protocol forl2-weeks. The ankle joint stiffness andneutral zone in inversion and eversion directions on the involved and uninvolved limbs wasmeasured at baseline, Mid, Post and post follow-up-intervention using a dynamometer. Results:' There was significant interaction observed between the group across the experimental trails p=.022). Similarly, there was also a significant effect of time differences observed on muscle strength concentric-eccentric inversionl20 degree (p=.000). Similarly, there was also a significant effect of time differences observed on concentric-eccentric eversion at 30 degree per second (p=.000).
