摘要

棒球投手的盂肱關節內旋活動度缺損發展往往開始於青春期前，更是演變為肩部不穩定症以及夾擠症的危險因子之一。盂肱關節內旋活動度缺損的成因可分為骨質的適應與軟組織的適應兩方面探討，包括肱骨後傾與肩關節後方軟組織的緊繃。盂肱關節內旋活動度缺損症狀也影響投手控球表現，原因可能來自於肩關節後方緊繃造成的水平內收活動度不足，以及肩胛骨在投擲中的動作異常。透過物理治療能減輕盂肱關節內旋活動度缺損症狀。學齡投手在青春期前提早進行預防性拉筋運動，應被視為減緩盂肱關節內旋活動度缺損症狀與肩部不穩定症發展的預防性復健訓練。

Glenohumeral internal rotation deficit (GIRD) in baseball pitchers commonly develops before puberty. GIRD is also a potential factor leading to subsequent shoulder instability or shoulder impingement. The etiology of GIRD can be explained in osseous adaptation and soft tissue adaptation, including humeral retroversion and posterior shoulder tightness. GIRD could also affect pitching control as a result of insufficient shoulder horizontal adduction and the scapular dyskinesis. GIRD could be improved through physical therapy. Early intervention with appropriate stretching programme may reduce the development of GIRD and subsequent shoulder instability.
