摘要：This study was performed in order to investigate the influence of exercise on muscle tone using the result of patellar tendon reflex. Subjects consisted of 23 healthy people, and 8 patients who were hyperflexia of patellar tendon reflex. And after each performed isokinetic exercise of the knee, measured amplitude of patellar tendon reflex. Healthy subjects showed a significantly longeramplitude at one, three, and five minutes after the exercise than that before the exercise. With respect to the patients, a significant increase in amplitude was observed at one and three minutes after the exercise. The results suggeted that incase physical therapy is performed on the patient who must consider the state of muscle tone, it is necessary to regulate both intensity and intervals of the exercise.
