This study validates the use of ambulatory EMG monitoring as a measure of exercise compliance. The model rehabilitative exercise used was the Prone Back Extension. Thirty-two undergraduate volunteers were videorecorded as they performed the exercise alone in a closed room. The correlation between a direct observation count of the number of repetitions and an independent EMG-based count was .95. EMG amplitude was examined by repetition and gender with regression and ANOVA. There were significant gender differences in the amplitude of EMG across repetitions. There were no significant differences by gender in the declining slope of amplitude across repetitions. This slope may represent a typical "fatigue" curve. Thus, not only the occurrence but also the intensity of exercise can be quantified.
本研究验证了动态肌电图监测作为运动依从性衡量指标的用途。所采用的康复锻炼模型是俯卧位后伸。32名本科志愿者在封闭房间内独自进行锻炼时被录像。重复次数的直接观察计数与基于肌电图的独立计数之间的相关性为0.95。通过重复次数和性别，采用回归分析和方差分析对肌电图幅度进行了检查。在重复过程中，肌电图幅度存在显著的性别差异。在重复过程中，幅度下降斜率在性别上无显著差异。该斜率可能代表典型的“疲劳”曲线。因此，不仅运动的发生情况，而且运动强度都可以进行量化。
