Spinal cord injury (SCI) often necessitates the use of a manual wheelchair, which can overload the shoulders and contribute to upper extremity (UE) pain. Currently, no standardized methods exist to assess UE kinematics during wheelchair propulsion. This study aimed to develop and evaluate a marker-based motion capture model for analyzing UE movement during wheelchair use, with a secondary goal of assessing test-retest reliability. The study was conducted in two phases: (1) development of the motion analysis model and (2) reliability testing. Eleven participants with SCI were included. Reliability was assessed using intraclass correlation coefficients (ICCs) across 15 movement parameters, including total range of motion and minimum and maximum movement values. The model demonstrated good test-retest reliability. For minimum movement, 12 of 15 parameters were significant (ICC = 0.681-0.965). For maximum movement, 13 of 15 were significant (ICC = 0.726-0.981). For total range of motion, 12 of 15 showed significant reliability (ICC = 0.596-0.952). In conclusion, the motion capture model showed promising reliability for assessing UE kinematics during wheelchair maneuvering in individuals with SCI. However, due to the small sample size, further research is needed to validate and refine the model.
脊髓损伤（SCI）通常需要使用手动轮椅，这可能会使肩部负担过重并导致上肢（UE）疼痛。目前，尚无标准化方法来评估轮椅推进过程中的上肢运动学。本研究旨在开发和评估一种基于标记的运动捕捉模型，用于分析轮椅使用过程中的上肢运动，其次要目标是评估重测信度。该研究分两个阶段进行：（1）运动分析模型的开发和（2）信度测试。纳入了11名脊髓损伤患者。使用组内相关系数（ICC）评估了15个运动参数的信度，包括总运动范围以及最小和最大运动值。该模型显示出良好的重测信度。对于最小运动，15个参数中的12个具有显著性（ICC = 0.681 - 0.965）。对于最大运动，15个参数中的13个具有显著性（ICC = 0.726 - 0.981）。对于总运动范围，15个参数中的12个显示出显著的信度（ICC = 0.596 - 0.952）。总之，该运动捕捉模型在评估脊髓损伤患者轮椅操作过程中的上肢运动学时显示出有前景的信度。然而，由于样本量较小，需要进一步研究来验证和完善该模型。
