Abstract

Background: Chronic ankle instability (CAI) is linked to mechanical and functional insufficiencies. Joint mobilisations are purported to be effective at treating these deficits. Purpose: We examined the effect of different treatment durations of a Grade IV anterior-to-posterior ankle joint mobilisation on weight-bearing dorsiflexion range of motion (WB-DFROM), posterior talar glide (PG), and dynamic postural control in individuals with CAI. Design: Randomized controlled clinical trial Methods: Forty-eight female athletes (age 22.8±4.8yrs) with unilateral CAI participated in the study. Participants were randomly assigned to one of three treatment conditions: 30s, 60s, and 120s. Treatment was provided to the injured limb on 3 separate occasions set 48 hours apart, and consisted of a Maitland Grade IV anterior-to-posterior talar joint mobilisation based on the participant’s initial group assignment. WB-DFROM, PG and the anterior (ANT), posteromedial (PM) and posterolateral (PL) reach directions of the Star Excursion Balance Test (SEBT) were measured bilaterally before and after each treatment. The uninjured limb acted as a control. Data was analysed using a two-way mixed model ANOVA and effect sizes calculated using hedge’s g. Results: Significant differences were detected following all treatment sessions for all outcome measures (p ≤ 0.001) and between treatment groups following session 1, 2 and 3 for all outcome measures (p ≤ 0.001). Effect sizes were ‘very large’ for all treatment groups for WB-DFROM, PG and ANT. There was substantial variation in effect sizes for PM and PL measures. Conclusions: Accessory mobilisations are an effective treatment for inducing acute changes in ankle motion and dynamic postural control in those with CAI, with higher treatment durations conferring greater improvements. This study adds clarity to the use of joint mobilisation treatments and will add to the current clinical practice strategy for those with CAI.
