A12-Weeks Multimodal Exercise Training on Ankle Joint Position Sense in Lateral Ankle Ligament Injury of Athletes

Abstract

Multimodal training is often the first choice of treatment in patients with grade II lateral ligament ankle injury; however, the effect of exercise on ankle proprioception is under debate. We investigated the effect of 12-week Multimodal training on ankle joint position sense using position-reposition test in subjects with grade II Lateral ankle ligament injury. Randomized controlled clinical trial; fifty-two young recreationally active athletes with grade II lateral ligament ankle injury were randomised to either a Group A n=13 (conventional Training), Group B n=13 (BOSU Exercise Training) Group C n=13 (neuromuscular training) Group D n=13 (combined intervention training). Subjects in the all groups were trained on the affected limb with static and dynamic components using the therapeutic equipment. The passive ankle joint position sense at 15°and 30° of ankle inversion/eversion on the affected limbs were measured at pre, mid, post and follow-up intervention using a Biodex Isokinetic dynamometer 4pro. Mean errors were compared between pre, mid, post and follow-up intervention using repeated measures of ANOVA. At baseline, the significant difference in the mean errors for all subjects was observed only at 30° of ankle inversion/eversion. Just the combined intervention group showed a substantial reduction in Mean error on the injured limb following intervention at both 15° of ankle inversion/eversion. At post-intervention, the decrease in Mean error in the involved leg was significantly higher in the combined intervention group than other groups at 30° of ankle inversion (P = 0.002). A significant difference in the Mean error was observed at 30° of ankle inversion/eversion. The balance training was effective in improving the deficit of ankle joint position sense in subjects with grade II lateral ligament ankle injury.
