초록

Purpose: The purpose of this study was to investigate the effect of strengthening exercises of hip abductors on muscle strengthand ambulation for patients with ACL reconstruction.
Methods: The subjects were randomly assigned to the intervention group (general exercise plus strengthening of hip abductors)or the control group (general exercise without the strengthening of hip abductors). Both groups participated in a six-weekexercise protocol after the surgery for ACL reconstruction. The knee strength test (quadriceps, hamstring, hip abductor) and gaitanalysis were performed in pretest and post-test.
Results: Muscle strength was measured using the Biodex system Ⅲ model (Biodex Medical System, Inc, NY, US). The resultsshowed no significant difference in knee strength (quadriceps, hamstring) between the two groups (p>0.05), however, therewas a significant difference in hip abductors (p<0.05). The gait analysis was measured with Gaitrite system (CIR System Inc, US).
Results of comparison between groups showed a significant increase in the step length of both groups. (p<0.05), and there was asignificant difference in the affected leg of the intervention group(p<0.05).
Conclusion: Exercise of hip abductors for patients with ACL reconstruction provides significant benefits with respect toimprovement of muscle strength in hip abductors, increasing the stride. This result indicates that a training program designed forACL reconstruction patients should include strengthening of the hip abductor. We think that further study is needed to determinethe relationship of hip muscles and knee joint for patients with ACL reconstruction.
