Electromyography systems are widely used within the field of scientific and clinical practices. The reliability of these systems are paramount when conducting research. The reliability of Myon 320 Surface Electromyography System is yet to be determined. This study aims to determine the intra-session and inter-day reliability of the Myon 320 Surface Electromyography System. Muscle activity from fifteen participants was measured at the anterior deltoid muscle during a bilateral front raise exercise, the vastus lateralis muscle during a squat exercise and the extensor carpi radialis brevis (ECRB) muscle during an isometric handgrip task. Intra-session and inter-day reliability was calculated by intraclass correlation coefficient, standard error of measurement and coefficient of variation (CV). The normalized root mean squared (RMS) surface electromyographic signals produced good intra-session and inter-day testing intraclass correlation coefficient values (range: 0.63-0.97) together with low standard error of measurement (range: 1.49-2.32) and CV (range: 95% Confidence Interval = 0.36-12.71) measures for the dynamic-and-isometric contractions. The findings indicate that the Myon 320 Surface Electromyography System produces good to fair reliability when examining intra-session and inter-day reliability. Findings of the study provide evidence of the reliability of electromyography between trials which is essential during clinical testing.
肌电图系统在科学和临床实践领域中被广泛使用。在进行研究时，这些系统的可靠性至关重要。Myon 320表面肌电图系统的可靠性尚未确定。本研究旨在确定Myon 320表面肌电图系统的日内和日间可靠性。在双侧前举运动期间，测量了15名参与者三角肌前部的肌肉活动；在深蹲运动期间，测量了股外侧肌的肌肉活动；在等长握力任务期间，测量了桡侧腕短伸肌（ECRB）的肌肉活动。通过组内相关系数、测量标准误差和变异系数（CV）计算日内和日间可靠性。归一化均方根（RMS）表面肌电信号在日内和日间测试中产生了良好的组内相关系数值（范围：0.63 - 0.97），同时动态和等长收缩的测量标准误差较低（范围：1.49 - 2.32）以及CV（范围：95%置信区间 = 0.36 - 12.71）。研究结果表明，在检查日内和日间可靠性时，Myon 320表面肌电图系统产生了良好到尚可的可靠性。该研究结果为肌电图在不同试验之间的可靠性提供了证据，这在临床测试中至关重要。
