肩關節的被動旋轉角度是評估肩關節重要的因素之一。過去的研究顯示肩關節旋轉角度和手臂的擺放位置有關,但是只限於cadaver model 或者只限於肩胛平面定量肩關節旋轉角度,尚未有研究探討人體肩關節的外轉及內轉角度和各個不同的位置下的關係。所以本篇目的即是要探討活體肩關節分別在不同上臂上舉角度和不同的肩關節上舉平面對於被動旋轉角度的影響。分別給予10個正常受試者優勢側數個間隔30度上臂上舉角度和不同肩關節上舉平面的位置4牛頓-米的旋轉力矩,利用電磁定位系統分別量測肩關節在不同位置、方向的內轉及外轉角度,結果似乎支持內轉和旋轉角度在大部分之上舉平面均會隨著上臂上舉而減少肩關節內轉及旋轉角度(相關係數:0.4-0.6),而外轉角度分別於矢狀面、肩胛平面往前30度、及肩胛平面往後60度的平面亦會隨著上臂上舉而減少外轉角度(相關係數:0.42-0.48)。分析結果也發現手臂上舉90度時,手臂置於越後面的肩胛平面其內轉角度越大(相關係數:0.556),而手臂上舉小於90度時,置於越前面的肩胛平面其外轉角度越大(相關係數:0.5-0.69)。
Passive rotation range of motion (ROM) is an important factor in shoulder joint behavior. Previous work has shown shoulder joint rotation ROMs to be significantly dependent on arm position. However, the studies were either in vitro cadaver studies, or basically qualitative in vivo investigation on one plane of elevation. No research has investigated the quantitative relationships of internal and external rotations of the shoulder joint at multiple positions in normal subjects in vivo. Therefore, this study investigated quantitatively using an electromagnetic motion tracking system in vivo passive rotation ROM at a known rotational moment in multiple angles of arm elevation and planes of elevation. In 10 normal subjects, dominant arm was tested for humerus ROM for every 30 degree of elevation in various elevation planes under 4 N•m of moment. Internal rotation angle was found to decrease with arm elevation in most planes of elevation (r=0.4-0.6, p<0.05). External rotation decreased with arm elevation in forward flexion, in 30 degree anterior to the scapular plane, and in 60 degree posterior to the scapular plane (r=0.42, 0.46, 0.48, p<0.05), respectively. With humerus elevated at the 90 degree of arm elevation angle, range of internal rotation increased significantly as planes of elevation move backward, while the opposite trend was observed in the range of external rotation at the angles less than 90 degree of arm elevation angle.
