| Research Abstract |
In four of 11 subjects, only M waves were observed on soleus, gastrocnemisu and tibialis anterior. The rest of the subjects showed no responses of EMGs on any muscles. The four subjects complained of spasticity of legs in their daily life. The spasticity was considered as training effects on paralyzed muscles. Although electric stimulations were conducted on the paralyzed muscles for six months in order to train the muscles, no response of EMG was found. In the rat experiment, the biochemical changes of muscles were found in the early stage of spinal cord section.
