The patient is a woman in her 50s after a right total hip replacement. When the patient had to stand on the right one leg to remove his pants from the left leg, his stability was reduced by his inability to hold the right single leg standing position. The chief complaint was "difficulty in removing pants. Therefore, the treatment goal was to improve the stability of dressing activity of pants in the standing position. Specifically, when the patient was in the right single leg standing position to remove his pants from the left leg, the right knee was displaced inward along with right hip adduction and internal rotation, and there was poor lateral inclination of the right lower leg due to right foot rotation. As a result, right lateral translation of the pelvis was poor and the patient was unable to maintain a right single leg standing position. Considering that the main problem was a decrease in external rotation muscle strength of the right hip joint, physical therapy was performed. As a result, the right hip joint could be held in an intermediate position of internal/external rotation in the right single leg standing position, and the pelvis shifted to the right side due to the lateral tilt of the right lower leg associated with the right foot rotation, which improved the stability of the movement. Isometric contraction of the right hip external rotators in the right single leg standing position was necessary to improve the patient's decreased stability of the pants changing movement in the standing position.
