Abstract
Lateral ankle Sprains are debatably the most common sports injury. Lateral ankle sprains are extremely common among physically active individuals due to sudden and abnormal stretching with excessive inversion or eversion that frequently result in pathologic laxity and sensorimotor deficits about the ankle. The present study was aimed to investigate the role of Conventional physiotherapy training (Group A), BOSU ball training (Group B), Neuromuscular training (Group C), and Combined intervention training (Group D) in improving dynamic balance, muscle strength and proprioception in participants with Grade II lateral ligament injury of the ankle. Fifty-two (52) subjects 32 male, and 20 females remained in the study for the statistical analysis. A two-way repeated measure of ANOVA revealed that there were significant differences among the groups. There was a significant effect observed after post assessment on proprioception at active and passive repositioning error at 15 and 5 degrees of inversion in Group C and Group D (p=.000). At the follow-up phase, the parameters of proprioception, dynamic balance and eversion strength were showed significant differences observed between Group A and Group B (p=.034), Group A and Group C (p=.036). Maximum voluntary isometric contraction (MVIC) of the peroneus longus, tibialis anterior, peroneus brevis muscle, showed significant differences in the mid-term assessment across intervention groups). Conventional training was beneficial in enhancing muscle-strength but was observed less effective in improving proprioception, dynamic balance and functional activities in participants,while BOSU ball aided training was observed as better than Conventional training in enhancing proprioception, muscle strength, dynamic balance and functional activities in participants with ankle lateral ligament injury. The combined intervention of BOSU ball and Neuromuscular training was observed to sensitise the sensory receptors of the muscle and the tendon in the form of increased proprioception and maximal voluntary isometric contraction thereby causing enhancement in proprioception of ankle joint, the strength of the muscle, dynamic balance and functional activities in participants suffering from grade II lateral ligament injury of the ankle. Conclusions: There have been numerous studies examining the different strength and proprioception training protocols. Some of these protocols have been successful at increasing dynamic stability, ankle strength, proprioception, or decreasing the risk of ankle injuries, Additionally, a new and novel combined training programme (BOSU ball and Neuromuscular training) for a twelve-week period improved the measures of dynamic balance, proprioception and muscle strength during athletes’ simulations, thus potentially reducing injury risk in healthy athletes.
