The purpose of this study was to discuss the situations under which we should train patients toincrease the quadriceps muscles strength when rising from sitting position. We measured integrated electromyography (IEMG) of the quadriceps muscles and floor reaction force when rising from a stool (40cm high) in various foot positions. The foot position of the measured side was changed by five stride length at open or close stances. The results were as follows : 1 ) vertical component of the floor reaction force was gradually increased as the position of the foot on the measured side changed from the front to the rear, especially at close stance ; 2) IEMG of the quadriceps muscles at close stance were significantly increased from the front to the rear position ; 3) in rear location, IEMG of the quadriceps muscles at close stance were higher than at open stance. In front location, IEMG of the quadriceps muscles at open stance were higher than at close stance. Thus, when training the patient for the rising from sitting position to increase the quadriceps muscle strength, we should consider foot stance as well as stride of the feet.
