Study aim
-
Evaluation of the effect of exercise therapy alone and combined with trigger point dry needling of peroneal muscles on muscular activity of the lower extremity during jump-landing task in athletes with chronic ankle Instability.
-
Design
-
Randomized, parallel group, placebo controlled trial, on 60 patients. Blocked randomization is used.
-
Settings and conduct
-
Control group: Subjects will complete progressive neuromuscular exercise, 2 sessions per week for 6 sequential weeks.
Intervention group 1: The subjects will complete the same exercise program as control group.Moreover they will receive dry needling of peroneus longus and peroneus brevis trigger points, 1 session per week for 6 weeks.
Intervention group 2: The subjects will complete the same exercise program as control group.Moreover they will receive placebo dry needling of peroneus longus and peroneus brevis trigger points, 1 session per week for 6 weeks.
-

Clinical presentation of trigger points in peroneal muscles.
-
Intervention groups
-
Intervention group 1: exercise therapy plus dry needling
Intervention group 2: exercise therapy plus placebo dry needling
control group: exercise therapy alone.
