摘要

目的：盂肱關節內旋活動度缺損常與棒球選手的肩關節受傷有關。然而是否影響到投手的運動表現仍然不清楚。因此，本研究的目的是評估藉由物理治療對改善盂肱關節內旋活動度缺損的效果及是否也能改善投手的運動表現。方法：本研究選取30位有盂肱關節內旋活動度缺損的投手，隨機方式分成實驗組16人接受深層按摩技術和伸展運動及14位控制組。評估包括兩側被動肩關節旋轉活動度和投擲運動表現。受試者分別在8週介入前後接受測試。結果：實驗組的慣用側手臂比控制組顯著增加在內旋角度與整體旋轉活動度（p＜.05）。此外，實驗組在擲球的方向及落點與目標點間距離也比控制組有顯著的改善（p＜.05）。結論：物理治療能有效減少盂肱關節內旋角度缺損與增加整體旋轉活動度，並且改善投擲的運動表現。

Purpose: Glenohumeral internal rotation deficit (GIRD) is associated with shoulder injury in baseball players. However, little is known pitchers with GIRD may affect the sport performance. Therefore, the purpose of this study was to evaluate the treatment effect of GIRD to pitching performance. Methods: Thirty baseball pitchers with GIRD were recruited in this study. Players were randomized into 2 groups. 16 pitchers in the experiment group received treatment with deep massage technique and stretching exercise. 14 pitchers were in the control group. The evaluation included bilateral passive shoulder rotation range of motion (ROM) and pitching performance. All tests were performed before and after 8 weeks intervention. Results: In the dominant arm, the experiment group showed significantly greater internal rotation ROM and total rotation ROM than that of control group (p＜.05). Furthermore, the pitching performance showed significant improvement (p＜.05). Conclusion: The treatment effect showed decreased GIRD, increased total rotation ROM, and improved pitching performance.
