本文的目的是提供参数的上肢肌肉骨骼模型的发展。5个上肢标本取自4具新鲜尸体。对每具尸体进行人体测量。从获得标本的尸体的人体测量值估计每个标本的节段惯性参数。使用3Space（TM）跟踪系统（Isotrack，PoIhemus）测量每个样本的肱骨、尺骨和桡骨在盂肱关节、肱骨尺关节和尺桡关节的不同运动中的三维运动学。从运动学数据中确定每个标本的盂肱关节瞬时旋转中心和肘关节屈曲和前臂旋前的瞬时旋转轴。对标本进行解剖，并使用3Space（TM）系统对上肢建模所需的肌肉起点和止点以及骨骼结构进行数字化。估计了肌肉起点和止点的形状。测量肌肉长度、体积和羽状角，以估计每块肌肉的生理横截面积。结果表明，盂肱关节旋转中心与关节几何中心的平均距离为4mm，手肘关节屈伸轴与旋后轴的平均夹角为94 °。这两个轴之间的最小距离约为4 mm。（C）1997 Elsevier Science Ltd.
The purpose of this paper was to provide parameters for the development of a musculoskeletal model of the upper extremity. Five upper extremity specimens were obtained from four fresh cadavers. Anthropometric measures were obtained for each cadaver. Segment inertial parameters were estimated for each specimen from anthropometric measures of the cadaver from which the specimen was obtained. The three-dimensional kinematics of the humerus, ulna, and radius in different movements of the glenohumeral, humeroulnar and ulnoradial joints were measured for each specimen using of the 3Space(TM) tracking system (Isotrack, PoIhemus). The instantaneous rotation center of the glenohumeral joint and the instantaneous rotation axes of elbow flexion and forearm pronation were determined for each specimen from the kinematic data. The specimens were dissected and the muscle origins and insertions and bony structures needed in upper extremity modeling were digitized using the 3Space(TM) system. The shapes of muscle origins and insertions were estimated. Muscle length, volume and pennation angle were measured for the estimation of physiological cross-sectional areas of each muscle. The results, which are given for one specimen, showed that the rotation center of the glenohumeral joint was very close to the geometric center of the joint with a mean distance of 4 mm. The mean angle between the flexion-extension and pro-supination axes of the elbow joint was 94 degrees. The minimum distance between these two axes was about 4 mm. (C) 1997 Elsevier Science Ltd.
