Volleyball players develop shoulder sports-related adaptations due to repetitive overhead motions. It is essential to differentiate between these sports-related adaptations and pathological patterns in clinical assessments, particularly on scapular resting posture and scapulohumeral rhythm. Using an electromagnetic tracking system, the 3D shoulder kinematics of 30 male elite asymptomatic volleyball players and a matching control group were recorded at rest and in eight humeral elevation positions, in 15-degree increments from 15 to 120 degrees. The results indicated that the dominant scapular resting posture of the volleyball group was more anteriorly tilted than the control group (Volleyball: mean = -12.02°, STD = 4.16°; Control: mean = -7.45°, STD = 5.42°; Mean difference = 4.57°; STD = 6.85°; CI95% = 2.1° to 7.1°). The scapulohumeral rhythm in the volleyball group showed greater scapular internal rotation (Volleyball: mean = 41.60°, STD = 9.14°; Control: mean = 35.60°, STD = 6.03°; mean difference = 6.02°, STD = 1.47°; CI95% = 4.80° to 7.25°) and anterior tilt (Volleyball: mean = -9.10°, STD = 5.87°; mean = -2.3°, STD = 9.18°; mean difference = 6.88°, STD = 0.66°; CI95% = 6.34° to 7.43°). These findings suggest that volleyball players have developed a sports-related scapular adaptive pattern. This information may be valuable for clinical assessment and rehabilitation planning in injured volleyball players and may aid in the decision-making process for determining a safe return-to-play after a shoulder injury.
排球运动员由于重复性的过顶动作而产生与肩部运动相关的适应性变化。在临床评估中，区分这些与运动相关的适应性变化和病理模式至关重要，尤其是在肩胛静止姿势和肩肱节律方面。使用电磁跟踪系统，记录了30名无症状男性精英排球运动员和一个匹配对照组在休息时以及从15度到120度以15度增量的八个肱骨抬高位置的三维肩部运动学数据。结果表明，排球组优势肩胛的静止姿势比对照组更向前倾斜（排球组：平均值=-12.02°，标准差=4.16°；对照组：平均值=-7.45°，标准差=5.42°；平均差异=4.57°；标准差=6.85°；95%置信区间=2.1°至7.1°）。排球组的肩肱节律显示出更大的肩胛内旋（排球组：平均值=41.60°，标准差=9.14°；对照组：平均值=35.60°，标准差=6.03°；平均差异=6.02°，标准差=1.47°；95%置信区间=4.80°至7.25°）和前倾（排球组：平均值=-9.10°，标准差=5.87°；平均值=-2.3°，标准差=9.18°；平均差异=6.88°，标准差=0.66°；95%置信区间=6.34°至7.43°）。这些发现表明排球运动员已经形成了一种与运动相关的肩胛适应性模式。这些信息对于受伤排球运动员的临床评估和康复计划可能具有重要价值，并且可能有助于在肩部受伤后决定安全恢复比赛的决策过程。
