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.

11名受试者中的4名仅在比目鱼肌、腓肠肌和胫骨前肌上观察到M波。其余受试者在任何肌肉上均无肌电图反应。这四名受试者在日常生活中主诉腿部痉挛。痉挛被认为是对麻痹肌肉的训练效果。虽然对瘫痪肌肉进行了6个月的电刺激以训练肌肉，但没有发现肌电图的反应。在大鼠实验中，在脊髓切断的早期发现了肌肉的生化变化。
