Current methods for the evaluation of upper extremity dynamics during wheelchair mobility in children are limited. The goal of this study was to characterize upper extremity joint kinematics during wheelchair mobility. A 3-D biomechanical model of the upper extremities is presented for kinematic assessment of manual wheelchair propulsion in children with Spinal Cord Injury (SCI). The bilateral upper extremity model consists of the thorax, upper arms, forearms, and hands. The model was applied to thirteen (13) children with SCI. Joint angles and joint ranges of motion of the shoulders, elbows, and wrists were quantified. Peak joint motions during the stroke cycle were compared between right and left sides for further insight to mobility patterns. This work will provide insight to be used in future kinetic studies of wheelchair mobility.
目前评估儿童轮椅移动过程中上肢动力学的方法有限。本研究的目的是描述轮椅移动过程中的上肢关节运动学特征。提出了一种用于脊髓损伤（SCI）儿童手动轮椅推进运动学评估的上肢三维生物力学模型。双侧上肢模型包括胸部、上臂、前臂和手部。该模型应用于13名脊髓损伤儿童。对肩部、肘部和腕部的关节角度和关节活动范围进行了量化。比较了中风周期中左右两侧的峰值关节运动，以进一步了解移动模式。这项工作将为未来轮椅移动的动力学研究提供参考。
