棒球运动员在内旋、外旋、全旋和水平内收的过程中，通常表现出不同的肘关节-肱骨活动范围。这些活动范围的改变似乎与投掷肩部损伤有关，通常涉及冈上肌腱；因此，我们的目的是研究大学棒球运动员肩关节活动范围改变与冈上肌腱变化之间的关系。为了利用皮尔逊相关系数来研究这种联系，我们测量了22名大学棒球运动员的关节内旋、外旋、总旋、水平内收活动范围和冈上肌腱厚度。因此，冈上肌腱厚度的增加与较大的内旋转不足之间存在显著的相关性(r=-0.520，P=0.013)。冈上肌腱厚度的增加往往与较大的外旋增加有关(r=0.394，P=0.073)。其他的活动范围与冈上肌腱的变化没有任何关系。这些结果可能表明，限制的关节内旋和过度的外旋增加增加了棒球运动员冈上肌腱异常的风险。
Baseball players commonly show altered glenohumeral range of motion during internal rotation, external rotation, total rotation, and horizontal adduction. These altered ranges of motion appear to be associated with throwing shoulder injuries, which frequently involve the supraspinatus tendons; thus, we aimed to examine the relationship between altered glenohumeral range of motion and supraspinatus tendon changes in collegiate baseball players. To investigate this association using the Pearson correlation coefficient, we measured glenohumeral internal rotation, external rotation, total rotation, and horizontal adduction ranges of motion and supraspinatus tendon thickness in 22 college baseball players. Consequently, there was a significant relationship between increase in supraspinatus tendon thickness and greater deficit of internal rotation (r = -0.520, P = 0.013). Increased supraspinatus tendon thickness tended to be associated with greater external rotation gain (r = 0.394, P = 0.073). No other range of motion had any relationship with supraspinatus tendon changes. These results might indicate that restricted glenohumeral internal rotation and excessive gain in external rotation increase the risk of supraspinatus tendon abnormalities in baseball players.
