This study aimed to investigate physiological and pathological Glenohumeral Internal Rotation Deficit (GIRD) in volleyball players with and without a history of shoulder pain. Volleyball players with a history of shoulder pain (n = 18) and without a history of shoulder pain (n = 18), who were matched in age, weight, height, BMI, years of experience and frequency of practice were recruited for this cross-sectional study. Shoulder internal and external rotation Range of Motion (ROM) was measured for the dominant and non-dominant shoulders of each participant using a digital inclinometer. Measurements of GIRD, External Rotation Gain (ERG), and Total Range of Motion (TROM) were calculated. There were significantly higher degrees of GIRD in the pain group (15.65⁰) than the no-pain group (9.06⁰) (p=0.004) and significantly higher differences in the TROM in the pain group (16.17⁰) than the no-pain group (10.17⁰) (p=0.007). There was no correlation between the level of pain and the presented ROM adaptations. The study showed that for volleyball players, pathological GIRD should be defined at 10-18⁰ degrees of GIRD that are accompanied by differences in the TROM that exceeds 8⁰.
本研究旨在调查有和没有肩部疼痛病史的排球运动员的生理性和病理性盂肱关节内旋不足（GIRD）情况。本横断面研究招募了有肩部疼痛病史（n = 18）和无肩部疼痛病史（n = 18）的排球运动员，这些运动员在年龄、体重、身高、体重指数、运动年限和训练频率方面相匹配。使用数字倾角仪测量每位参与者优势肩和非优势肩的肩部内旋和外旋活动范围（ROM）。计算GIRD、外旋增益（ERG）和总活动范围（TROM）的测量值。疼痛组的GIRD程度（15.65°）显著高于无疼痛组（9.06°）（p = 0.004），疼痛组的TROM差异（16.17°）也显著高于无疼痛组（10.17°）（p = 0.007）。疼痛程度与所呈现的ROM适应性之间没有相关性。该研究表明，对于排球运动员，病理性GIRD应定义为GIRD在10 - 18°，同时TROM差异超过8°。
