後方歩行の左立脚相に左股関節が内転しないまま左膝関節が屈曲し右後方へ不安定となる廃用症候群の一症例

抄録

We present a case of backward walking in which adduction of the left hip joint was not possible in the left stance phase due to muscle weakness in left hip joint abduction. In addition, the left knee joint was bent because of the decreased muscle strength in left knee joint extension, and the thigh was tilted backward and became unstable during movement toward the right. Physiotherapy was performed for 40 minutes per session twice a week to improve the muscle strengths of left knee joint extension and left hip joint abduction. Following improvement in the muscle strength of left hip joint abduction in the left stance phase, the weight shift to the left increased. In addition, the safety and stability of backward walking were improved by prevention of the backward inclination of the thigh, caused by bending of the left knee joint, by an increase in the muscle strength of left knee joint extension.
