OBJECTIVE To investigate the evidence of measurement properties of isokinetic dynamometry (ID) for assessment of shoulder muscle strength in healthy individuals and patients with non-neurological shoulder pathology. DATA SOURCES Cochrane Central Register of Controlled Trials (CENTRAL), Pubmed, EMBASE, and PEDro were searched up to February 2020 without restrictions. Reference lists and citations were hand-searched. STUDY SELECTION Two review authors independently included studies that met the following criteria: 1) evaluating measurement properties of ID when used on the glenohumeral joint and 2) included individuals' ≥ 18 years. Studies including patients with neurologic, neuromuscular, or systemic diseases or critical illness were excluded. DATA EXTRACTION The quality assessment and data synthesis were performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology. DATA SYNTHESIS Twenty-one studies with a total of 597 participants were included. The results were combined separately for isometric, concentric, and eccentric test mode, for the velocities 30-60°/s, 90°/s, 120°/s and 240°/s, for the seated, supine and standing position, and for internal rotation (IR), external rotation (ER), and the ER/IR ratio. The reliability of ID was overall sufficient with the majority of intraclass correlation coefficients (ICC) ≥0.70. The quality of evidence was moderate or low for 20 out of 30 strata examined. The measurement error results were rated as insufficient for all strata. The standard error of measurement in percent (%SEM) ranged from 4% to 28%. The quality of evidence varied depending of strata examined. CONCLUSION The reliability of ID for measurement of shoulder strength was overall sufficient for all positions, velocities and mode of strength. The measurement error was not sufficient. As most studies used the seated position, the velocities 30-60°/s or 120°/s, and the concentric test mode, the quality of evidence was highest for these conditions.

用于评估肩部肌肉力量的等速测力法的测量特性：系统评价

目的 研究等速测力法 (ID) 用于评估健康个体和非神经性肩部病变患者肩部肌肉力量的测量特性的证据。数据来源 Cochrane 对照试验中心注册中心 (CENTRAL)、Pubmed、EMBASE 和 PEDro 无限制地检索至 2020 年 2 月。手动搜索参考列表和引文。研究选择 两位综述作者独立纳入了符合以下标准的研究：1) 评估用于盂肱关节时 ID 的测量特性，2) 包括年龄≥18 岁的个体。包括患有神经系统、神经肌肉或全身疾病或危重疾病的患者的研究被排除在外。数据提取 根据基于共识的健康测量仪器选择标准 (COSMIN) 方法进行质量评估和数据合成。数据综合 包括 21 项研究，共有 597 名参与者。等长、同心和偏心测试模式的结果分别合并，速度为 30-60°/s、90°/s、120°/s 和 240°/s，坐姿、仰卧和站立姿势，以及用于内旋 (IR)、外旋 (ER) 和 ER/IR 比率。ID 的可靠性总体上是足够的，大多数组内相关系数 (ICC) ≥0.70。在检查的 30 个分层中，有 20 个的证据质量为中等或低。所有地层的测量误差结果均被评为不充分。以百分比表示的测量标准误差 (%SEM) 范围为 4% 至 28%。证据质量因检查的层而异。结论 ID 用于测量肩部力量的可靠性对于所有位置、速度和力量模式来说总体上是足够的。测量误差不充分。由于大多数研究使用坐姿、30-60°/s 或 120°/s 的速度以及同心测试模式，因此这些条件下的证据质量最高。
