Silent periods are transient stops of muscle activity that are induced by mechanical or electrical stimulus. The current report describes a new algorithm which enables automatic detection and measurement of silent periods that occur in the EMG of human masticatory muscles during chewing efforts together with jaw positions in space at the occurrence of the silent periods. The EMG signal for detection of the silent period is modeled based on the observation of the EMG records induced from the jaw-closing muscles during chewing efforts in seven volunteer subjects. The algorithm for automatic detection and measurement of the EMG silent period has been applied successfully to real EMG data and the performance of the software was confirmed to be sufficiently reliable. The results of the analysis are stored in a biosignal database for possible clinical use.
静息期是由机械或电刺激诱发的肌肉活动短暂停止。本报告描述了一种新算法，该算法能够自动检测和测量在咀嚼过程中人类咀嚼肌肌电图（EMG）中出现的静息期，以及静息期出现时颌骨在空间中的位置。用于检测静息期的EMG信号是基于对7名志愿者在咀嚼过程中下颌闭合肌诱发的EMG记录的观察进行建模的。用于自动检测和测量EMG静息期的算法已成功应用于实际EMG数据，并且软件性能被证实具有足够的可靠性。分析结果存储在生物信号数据库中以供临床使用。
