Abstract

INTRODUCTION
The purpose of this study was to compare isokinetic strength of ankle and hip joint between involved and non-involved side in women with chronic inversion ankle sprain.
METHOD
A total of 26 subjects with unilateral chronic inversion ankle sprain were recruited. We measured hip abductor muscle weakness with Trendelenburg's test and isokinetic strength of ankle and hip joint.
RESULT
First, there were significant differences between involve and non-involve side in ankle evertor isokinetic strength such as peak torque, peak torque/body weight, total work at 30°/sec and peak torque/body weight at 180°/sec. Second, there were significant differences between involve and non-involve side in hip abductor isokinetic strength such as peak torque, peak torque/body weight, total work at 30°/sec and peak torque/body weight at 180°/sec.
CONCLUSION
It shown that chronic inversion ankle sprain cause ankle evertor and hip abductor weakness therefore, muscle strength training should be included around ankle and hip joint for rehabilitation.
