This study aimed to determine the absolute and relative reliability of concentric and eccentric flexion, extension, horizontal abduction, and adduction movements of the shoulder using a functional electromechanical dynamometer (FEMD). Forty-three active male university students (23.51 ± 4.72 years) were examined for concentric and eccentric strength of shoulder flexion, extension, horizontal abduction, and horizontal adduction with an isokinetic test at 0.80 m·s. Relative reliability was determined by intraclass correlation coefficients (ICCs) with 95% confidence intervals. Absolute reliability was quantified by the standard error of measurement (SEM) and coefficient of variation (CV). Reliability was very high to extremely high for all movements on concentric and eccentric strength measurements (ICC: 0.76-0.94, SEM: 0.63-6.57%, CV: 9.40-19.63%). The results of this study provide compelling evidence for the absolute and relative reliability of concentric and eccentric flexion, extension, horizontal abduction, and horizontal adduction shoulder isokinetic strength tests in asymptomatic adults. The mean concentric force was the most reliable strength value for all tests.
本研究旨在使用功能电动测力计（FEMD）确定肩部的同心和偏心屈曲、伸展、水平外展和内收运动的绝对和相对可靠性。43 名活跃的男性大学生（23.51 ± 4.72 岁）接受了等速测试，以 0.80 m·s 的速度测试肩部的同心和偏心屈曲、伸展、水平外展和水平内收的力量。相对可靠性通过具有 95%置信区间的组内相关系数（ICC）确定。绝对可靠性通过测量标准误差（SEM）和变异系数（CV）来量化。所有运动在同心和偏心力量测量方面的可靠性均非常高到极高（ICC：0.76-0.94，SEM：0.63-6.57%，CV：9.40-19.63%）。本研究结果为无症状成年人的同心和偏心屈曲、伸展、水平外展和水平内收肩部等速力量测试的绝对和相对可靠性提供了有力证据。在所有测试中，平均同心力是最可靠的力量值。
