Electromyographic study for evaluation of jaw muscle function usingdigital signal processing technology

本研究的目的是利用信号处理技术检测表面肌电信号以评估口腔颌面功能。用针电极和多道阵列表面电极同时记录肌肉活动。利用信号平均技术，计算出与针电信号同步的表面肌电信号。这些信号表明肌肉内部的局部活动是否反映在表面肌电上。建议利用数字信号处理技术对表面肌电信号进行处理，推测肌肉内部的活动情况。这些结果将有助于表面肌电信号检测的发展。

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.
