Extensor lag of the knee joint is a well-known phenomenon. This requires intensive physical therapy. One of the important factors of this phenomenon is believed to be reflex inhibition of voluntary movement due to stimulus to mechanorecepter in the soft tissue around the knee joint. In order to clarify the effect of ultrasound on the mechanoreceptor in the normal knee joint, strength of quadriceps femoris of 24 knees was investigated by the application of ultrasound. As a result, it was revealed when subjects complained of dull-pain or intolerable pain during exposing ultrasonic energy to the region of the supra-patellar pouch, maximum voluntary forces of quadriceps femoris decreased significantly. This result suggests that muscle strength of quadriceps femoris was affected by the stimulation of mechanoreceptor by ultrasound application.
