Effects of a Neuromuscular Reeducation Program on the Postural Control in Gymnasts with Chronic Ankle Instability

摘要

Chronic ankle instability (CAI) is associated to the mechanical and/or functional instability of the ankle, being described as often residual change after sprain. Objective: To analyze the effects of a neuromuscular reeducation program for six weeks, in postural sway (PS) and time to stabilization (TS), in functional tests, in asymptomatic gymnasts and in gymnasts with CAI. Methods: The postural variation was evaluated within sample of 24 gymnasts - 9 with CAI (experimental group) and 15 healthy ones (control group) through a pressure platform, before and after applying the exercise program. Results and Discussion: In the instability group it was observed an improvement in PS and TS in a single limb static stance with open and closed eyes, and after a landing of an anterior jump, medial and lateral side. In the control group a decrease of the PS in a single-limb static stance with eyes open and after the landing of a medial side jump was verified; improvement of the time to stabilization in the landing of lateral and medial side jump, after applying the exercise program. Conclusion: A neuromuscular reeducation program had a positive effect in the improvement of the postural control in gymnasts with or without CAI.
