PURPOSE: To evaluate the effects of joint mobilization, in which movement is applied to the ankle's dorsiflexion range of motion, on dynamic postural control and on the self-reported instability of patients with chronic ankle instability (CAI). METHODS: A double-blind, placebo-controlled, randomized trial with repeated measures and a follow-up period. Ninety patients with a history of recurrent ankle sprain, self-reported instability, and a limited dorsiflexion range of motion, were randomly assigned to either the intervention group (Joint Mobilizations, 3 weeks, two sessions per week) the placebo group (sham mobilizations, same duration as joint mobilization) or the control group, with a 6 months follow-up. Dorsiflexion range of motion (DFROM), Star Excursion Balance Test (SEBT) and CAI Tool (CAIT) were outcome measures. A separate 3x4 mixed model analysis of variance was performed to examine the effect of treatment conditions and time, and intention-to-treat (ITT) analysis was applied to evaluate the effect of the independent variable. RESULTS: The application of joint mobilization resulted in better scores of DFROM, CAIT, and SEBTs in the intervention group when compared with the placebo or the control groups (p < 0.001). The effect sizes of group-by-time interaction, measured with eta-squared, oscillated between 0.954 for DFROM and 0.288 for SEBT posteromedial distance. In within-group analysis, the manipulation group showed an improvement at 6 months follow-up in CAIT (mean 5.23, CI 95% 4.63 to 5.84), DFROM (mean 6.77, CI 95% 6.45 to 7.08), anterior SEBT (mean 7.35, CI 95% 6.59 to 8.12), posteromedial SEBT (mean 3.32, CI 95% 0.95 to 5.69), and posterolateral SEBT (mean 2.55, CI 95% 2.20 to 2.89). CONCLUSION: Joint mobilization techniques applied to subjects suffering from CAI were able to improve ankle DFROM, postural control, and self-reported instability. These results suggest that joint mobilization could be applied to patients with recurrent ankle sprain to help restore their functional stability.
