The purpose of this study was to examine intertester and intratester reliability of the shoulder medial rotation test (MRT) and reliability differences depending on examiner expertise.
Seventeen athletes with chronic shoulder pain participated in the study. Four independent observers with different experience levels simultaneously rated MRT performance as "correct" or "incorrect," after a standardized assessment protocol, the same day (for intertester reliability) and in a 7-day interval (for intratester reliability).
The intrarater reliability was admissible for 2 experts and one novice, with κ values ranging between 0.32 to 0.76 and poor for one novice (κ <0). Interrater agreement for all 4 assessors demonstrated slight agreement (κ = 0.06; 95% confidence interval: 0.06-0.47), increasing to fair agreement (κ = 0.33; 95% confidence interval: 0.21-0.69) when comparing the MRT findings between the 2 experienced assessors. Practice with the MRT in novices only marginally improved their level of agreement.
Reliability of the MRT for detecting movement control of the shoulder girdle was fair at best for experienced examiners and poor overall. Dexterity and repetitive performance of the test is necessary for correct interpretation of the MRT.
本研究旨在检验肩部内旋试验（MRT）的测试者间信度和测试者内信度，以及根据检查者专业水平的信度差异。
17名患有慢性肩部疼痛的运动员参与了本研究。4名具有不同经验水平的独立观察者在标准化评估方案后，于同一天（用于测试者间信度）和间隔7天（用于测试者内信度）同时将MRT表现评定为“正确”或“错误”。
2名专家和1名新手的测试者内信度可接受，κ值在0.32至0.76之间，而1名新手的信度较差（κ<0）。所有4名评估者的测试者间一致性显示为轻微一致（κ=0.06；95%置信区间：0.06 - 0.47），当比较2名经验丰富的评估者之间的MRT结果时，一致性提高到中等一致（κ=0.33；95%置信区间：0.21 - 0.69）。新手对MRT的练习仅略微提高了他们的一致水平。
对于经验丰富的检查者，MRT检测肩胛带运动控制的信度充其量为中等，总体较差。测试的灵活性和重复性表现对于正确解释MRT是必要的。
