The aim of this study was to examine surface electromyography for evaluating stomatognathic function by using signal processing technology. The muscle activity was recorded simultaneously with the needle electrode and the multi channel array surface electrode. With the signal-averaging technique, the surface electromyogram (EMG) signals that synchronized with the needle EMG signals were calculated. These signals indicated whether the regional activity inside the muscle was reflected on the surface EMG. It is suggested that the activity inside muscle would be speculated from the surface EMG processed by the digital signal processing technology. These results may contribute the development of the surface EMG inspection.

本研究的目的是利用信号处理技术检查表面肌电图，以评估口颌功能。用针电极和多通道阵列表面电极同时记录肌肉活动。采用信号平均技术，计算与针刺肌电信号同步的表面肌电信号。这些信号表明肌肉内部的区域活动是否反映在表面肌电图上。建议利用数字信号处理技术处理的表面肌电信号推测肌肉内部的活动。这些结果可能有助于表面肌电图检测的发展。
