The purpose of this study was compared to MTICs(maximal tolerated isometric contraction), decrement and recovery. For this, using isokinetic exercise analysis device(Biodex Medical Systems Inc., Biodex System 3PRO, USA), low rate(20 Hz) and high rate(100 Hz) NMES(neuromuscular electrical stimulation) were applied to the quadriceps muscles of fifteen patients with spastic hemiplegia caused by lesions in the central nervous system. The results were as follows: 1. It was shown to fast decrement in the middle of phase at low rate NMES and to slow decrement of MTIC response at high rate NMES(p<.01). 2. It was shown to fast recovery at high rate NMES and to slow recovery at low rate NMES in recovery tendency of MTIC(p<.01). These conclusions suggest that NMES of high rate caused to slow fatigue and fast recovery different from low rate NMES.
