Myoelectric signals (MES's) from the medial deltoid, posterior deltoid and medial trapezius were analyzed during 90 degree abduction-adduction cycles of arm movement. Two healthy males were utilized as subjects. The MES's records were divided into sub-sections of 50 ms of duration, and each segment was described by a suitable model. The models were based on autoregressive integrated moving average (ARIMA) processes. Several distinct phases were discerned within a given movement cycle, each phase being associated with a distinct type of ARIMA process. Phasic relations among the three muscles were then revealed. A simple test was suggested to detect the onset of muscle activity in real-time situations.
在手臂进行90度外展-内收循环运动期间，对来自三角肌内侧、三角肌后部和斜方肌中部的肌电信号（MES）进行了分析。选取了两名健康男性作为研究对象。MES记录被划分为时长50毫秒的子部分，每个片段用一个合适的模型进行描述。这些模型基于自回归积分滑动平均（ARIMA）过程。在给定的运动周期内识别出了几个不同的阶段，每个阶段都与一种不同类型的ARIMA过程相关联。随后揭示了三块肌肉之间的相位关系。还提出了一种简单的测试方法，用于在实际情况下实时检测肌肉活动的开始。
