During the stance phase, or when standing on one leg, the weakened abductor muscles allow the pelvis to tilt down on the opposite side. To compensate, the trunk lurches to the weakened side to attempt to maintain a level pelvis throughout the gait cycle. When the hip abductor muscles (gluteus medius and minimus) are weak or ineffective, the stabilizing effect of these muscles during gait is lost. When standing on the right leg, if the left hip drops, it is a positive right<unk>  sign (the opposite side drops because the hip abductors on the right side do not stabilize the pelvis to prevent the droop). When the patient walks, if he swings his body to the right to compensate for left hip drop, he will present with a compensated<unk> . The patient exhibits an excessive lean in which the upper body is thrust to the right to keep the center of gravity over the stance leg.
