Abstract：
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-1. 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.
摘要：
本研究旨在确定同心和偏心屈曲的绝对和相对可靠性，扩展,水平绑架,以及使用功能机电测功机（FEMD）的肩部内收运动。检查了43名活跃的男大学生（23.51±4.72岁）的同心和偏心强度，扩展,水平绑架,水平内收，等速试验为0.80m·s-1。相对可靠性由具有95%置信区间的组内相关系数(ICC)确定。绝对可靠性通过测量的标准误差(SEM)和变异系数(CV)来量化。对于同心和偏心强度测量的所有运动，可靠性都很高到极高（ICC：0.76-0.94，SEM：0.63-6.57％，CV：9.40-19.63%）。这项研究的结果为同心和偏心屈曲的绝对和相对可靠性提供了令人信服的证据，扩展,水平绑架,无症状成人水平内收肩关节等速力试验。平均同心力是所有测试中最可靠的强度值。
