CONTEXT
The hip abductor muscles, mainly the gluteus medius, are responsible for controlling hip adduction in a closed kinetic chain. Frontal plane knee alignment, assessed during functional activities such squatting, jumping and running, may overload joint structures, like the anterior cruciate ligament and patellofemoral joint. The hand-held dynamometer is reliable and effective for testing the muscular strength of the hip abductors.
OBJECTIVES
- To assess the concurrent validity between the gluteus medius clinical test and a maximum isometric force test of the hip abductors using the hand-held dynamometer; (2) to determine the intra and inter-examiner reliability for the application of the gluteus medius clinical test; and (3) to describe reference values of gluteus medius clinical test on a population of youth athletes.
DESIGN
Cross-sectional.
METHODS
Thirty healthy individuals were recruited for validity and reliability testing. On the first day, participants performed the maximal isometric test of the hip abductors, measured via hand-held dynamometry. On the following week, the gluteus medius clinical test was performed. Intraclass correlation coefficients (ICC) were computed for the reliability analysis, with a 95% confidence interval. To generate reference values, the gluteus medius clinical test was performed on 273 athletes.
RESULTS
The results of this study indicated a weak positive correlation (r = 0.436, p = 0.001) between tests, which indicates that they examine different domains of gluteus medius muscle function, likely endurance and muscle strength. The magnitude of computed ICCs (>0.95) indicates excellent intra- and inter-examiner reliability.
CONCLUSION
The findings of the current study indicate that the gluteus medius clinical test is reliable and examines a domain of muscular function not fully captured by HHD. The clinical test developed in this study is low-cost and can be included for gluteus medius assessment.

背景
髋外展肌，主要是臀中肌，负责在闭链运动中控制髋关节内收。在诸如深蹲、跳跃和跑步等功能活动中评估的额状面膝关节对线可能会使关节结构（如前交叉韧带和髌股关节）过载。手持测力计对于测试髋外展肌的肌力是可靠且有效的。
目的
- 使用手持测力计评估臀中肌临床测试与髋外展肌最大等长力量测试之间的同时效度；（2）确定臀中肌临床测试应用的检查者内和检查者间信度；（3）描述青年运动员群体中臀中肌临床测试的参考值。
设计
横断面研究。
方法
招募30名健康个体进行效度和信度测试。第一天，参与者通过手持测力计进行髋外展肌的最大等长测试。在接下来的一周，进行臀中肌临床测试。计算组内相关系数（ICC）用于信度分析，置信区间为95%。为了生成参考值，对273名运动员进行了臀中肌临床测试。
结果
本研究结果表明测试之间存在弱正相关（r = 0.436，p = 0.001），这表明它们检查的是臀中肌功能的不同领域，可能是耐力和肌肉力量。计算出的ICC值（>0.9）表明检查者内和检查者间信度极佳。
结论
本研究结果表明臀中肌临床测试是可靠的，并且检查了手持测力计未完全涵盖的肌肉功能领域。本研究中开发的临床测试成本低，可用于臀中肌评估。
