comparative effects of wobble board and trx training on balance in athletes with functional ankle instability

Purpose: the present study aimed to compare the effect of wobble board and trx training on static and dynamic balance in athletes with functional ankle instability.methods: a total of 35 athletes with functional ankle instability were randomly divided into three groups: wobble board training, trx training, and control. the anthropometric variables and the static and dynamic balance indices of subjects were evaluated using the biodex balance assessment tool in three stages: pre-test, post-test, and follow-up (6 weeks after post-test). subsequently, the training groups performed their relevant exercises for 6 weeks. the repeated-measures analysis of variance and bonferroni post-hoc test were used for the statistical analyses. the significance level was considered <0.05.results: the repeated-measures anova results showed that the static and dynamic balance indices of the subjects in the training groups significantly improved from the pre-test to the post-test (p≤0.05). additionally, the results indicated that 6 weeks after the post-test stage, the positive effects of wobble board and trx training did not diminish in either training group (p≤0.05). however, the balance indices evaluated in the control group did not show any significant difference at any of the measurement points (p≥0.05). conclusion: athletes with functional ankle instability often struggle with deficiencies in both static and dynamic balance, which increases their vulnerability to re-injury during dynamic movements. our findings suggest that incorporating functional-based approaches, such as wobble-board and trx exercises, can serve as effective strategies for enhancing balance in athletes with functional ankle instability.
