摘要

Thirty hemiplegics and 15normal persons were enrolled in this study. Measuring the recovery time of H reflex by dual stimulation technique to tibial nerve was performed to evaluate the excitability of spinal motoneurons. It was found that the recovery time of H reflex in normal persons and nonhemiplegic sides of hemiplegics was 57.0±27.3 msec and 57.3±21.4 msec respectively. The recovery time of hemiplegic sides was 37.5±12.8 msec and it was very significantly shorter than the normal ones. The shortening of the recovery time showed good correlation with the neurological recovery as well as the spasticity of the patients. These findings approved that with higher frequency of dual stimulation the recovery time of H reflex is an useful index in the clinical evaluation of spinal motoneuron excitability.
