WebJun 14, 2024 · We used inverse dynamics and static optimization to solve for glenohumeral joint forces during a simulated shoulder elevation. We generated 1000 AnyBody models by uniformly distributing the following input parameters: subject height, scapulohumeral rhythm, humeral head radius, and acromiohumeral interval. WebApr 8, 2024 · If the scapulothoracic rhythm is properly coordinated, an individual will have approximately 1200of glenohumeral abduction and 600 of scapular upward rotation. Therefore there is roughly a 2:1 ratio of movement in the glenohumeral joint to that of the scapulocostal articulation. python mahjong
