腦中風患者患肢肩痛的肌電圖檢查

Abstract

A total of 50 patients, who had developed hemiplcgia or hcmiparesis as a result of a cerebral vascular disease, were collected for electrophysiologic study. All of these patients were free of peripheral nerve disorder or shoulder joint pathology.MNCV, SNCV, F latencies of bil median nerves and concentric needle eiectromyographic examination were done. The relationship between electrophysiological findings and clinical features of the patients was analyzed. A positive correlation between shoulder pain and presence of shoulder subluxation or shoulder ROM limitation was found. However, no significant correlation of shoulder pain to the severity of motor deficit, sensory impairment or spasticUy of the hemiPegic side was found. The mean MNCV and F latency of median nerve were delayed, as compared with the contralateral normal arm (P＜0.05), but no significant difference was found in SNCV. There was a negative correlation between spontaneous activities and muscle strength in the hemiplegic arm (P＜0.025). However, the appearance of spontaneous activity showed no correlation to the severity of spasticity, sensory impairment and shoulder subluxation. Spontaneous EMG activity was observed in 94% of the stroke patients with shoulder hand syndrome or tha-lamic pain, whereas only in 28% of those stroke patients without shoulder pain (P＜0.001). This findings strongly suggested that there is probably some relationship between the appearance of spontaneous EMG activities and shoulder pain on hemiplegic limbs.
