| Research Abstract |
Catch property is a force enhancement produced in the muscle when a brief, high frequency burst of pulses is added to a low frequency electrical stimulation train. In functional electrical stimulation (FES), low frequency stimulation of approximately 20 Hz has primarily been used to reduce muscle fatigue. In the present study, the effects of catch property on muscle fatigue were analyzed using intermittent electrical stimulation. The results showed that, compared to conventional low frequency stimulation, low frequency stimulation taking advantage of the catch property significantly increased the maximum muscle force and workload and decreased muscle fatigue. The results of the present study suggest that catch property is useful in clinical administration of FES.
