Abstract

PURPOSE
The purpose of this study is to analyze the compensatory motion and extent of the patient with leg length discrepancy.
MATERIALS AND METHODS
Thirty seven patients with leg length discrepancy were tested by conventional gait analysis from 2003 to 2012. The patients were divided into mild, moderate, and severe groups. Pelvic obliquity, hip flexion, hip abduction, knee flexion in stance and swing phase, and ankle plantar flexion were measured with regard to affected and unaffected limb.
RESULTS
Pelvic obliquity, hip flexion, hip abduction, knee flexion in swing phase, and ankle plantar flexion were significantly difference between affected and unaffected limb. The range of motions in pelvic obliquity and ankle plantar flexion of affected limb were significantly higher according to severity of limb length discrepancy.
CONCLUSION
The patients with limb length discrepancy have the different compensatory motion according to affected side and severity. We should adjust the target of treatment in consideration of limb length discrepancy.
