ABSTRACT
INTRODUCTION: Ankle sprain is a common musculoskeletal injury that leads to recurrent instability. Repeated ankle sprain can be a mechanism for creating trigger point. Proper treatment of trigger points, in addition to preventing recurrence of sprains, may reduce pain and improve muscle function. This improvement can be the result of preserving the surrounding tissues from excessive pressure. OBJECTIVE: Investigate the added value of dry needling into perturbation training protocol for chronic ankle sprain. DESIGN: Randomized clinical trial; assessor-blind; before and after comparison. SETTING: Treatment of patients referred to the institutional rehabilitation clinics. MAIN OUTCOME MEASURE(S): Functional assessment with FAAM questionnaire score, Pain with NPRS scale, ankle instability severity with Cumberland tool. METHODS: Twenty-four patients with chronic ankle instability participated in this clinical trial and were randomly divided into two groups. Intervention was 12 sessions in which one group received only perturbation training and the other group received perturbation training along with dry needling. Repeated measures ANOVA was used to investigate the effect of treatment. RESULTS: Data Analysis showed significant difference in NPRS and FAAM and Cumberland score before and after treatment in each group (P < 0.001). Comparison of the results between the groups did not show any significant difference (P > 0.05). CONCLUSION: The findings showed that adding dry needling technique to the perturbation training does not have greater effects on the pain and function of patients with chronic ankle instability.
