Abstract
Abstract
Background and Aims: Many individuals who suffer a lateral ankle sprain will develop chronic ankle instability (CAI). Individuals with CAI demonstrate postural control differences as well as patient-reported outcomes compared with healthy individuals. However, the role of aquatic exercise in this population was not well investigated. The purpose of this study was to evaluate the effectiveness of 8 weeks of aquatic exercise intervention on dynamic balance and self-reported instability in patients with CAI.
Methods: Forty patients with CAI were randomly allocated to intervention or control groups (N = 20 per group). The intervention group performed 8 weeks of aquatic exercise (1 hour per session, 3 times per week). Outcome measures included postural control and self-reported instability feeling assessed by the Y-Balance test and the Cumberland Ankle Instability Tool, respectively. A repeated-measures analysis of variance was used to compare groups and time points. Significant level was considered as p≤0.05 in all statistical analyzes.
Results: There was observed significant improvement in all Y-Balance test reach distances (anterior [F = 21.84, P < .001]; posteromedial [F = 29.18, P < .001], and posterolateral [F = 24.30, P < .001]) in the intervention group with no change in the control group (P > .05). The intervention group demonstrated significant improvement on self-reported instability feeling assessed by the Cumberland Ankle Instability Tool questionnaire (F = 17.43, P < .01).
Conclusions: The obtained results suggested that 8 weeks of aquatic exercise have positive effects on postural control and self-reported instability feeling in patients with chronic ankle instability. Clinicians may consider aquatic exercise intervention to improve postural control and self-reported instability feeling for patients with CAI.
