本研究的主要目的是检查轮椅以慢速和中速推进时肩部的运动学和动力学。 27 名截瘫患者以 0.9 m/s 和 1.8 m/s 的速度推动轮椅，运动分析系统捕捉他们上肢的运动，SMART（轮）同时记录他们的推轮动力学。类内 R 相关性和 Cronbach 系数 alpha 统计表明，所有肩部参数在划水和速度之间稳定且一致。肩部表现出更大的运动范围，肩部的力和力矩增加了 1.2 至 2.0 倍 (p < 0.1)。推进过程中肩部定位和相关的肩部峰值负载可能是识别手动轮椅使用者面临肩部疼痛和损伤风险的重要指标。
The primary objective of this study was to examine the kinematics and kinetics of the shoulder during wheelchair propulsion at a slow and moderate speed. Twenty-seven individuals with paraplegia propelled their wheelchairs at speeds of 0.9 m/s and 1.8 m/s while a motion analysis system captured movements of their upper limbs and SMART(Wheel)s simultaneously recorded their pushrim kinetics. Intraclass R correlation and Cronbach's coefficient alpha statistics revealed that all shoulder parameters were stable and consistent between strokes and speeds. The shoulder exhibited a greater range of motion, and forces and moments at the shoulder were 1.2 to 2.0 times greater (p 0.1). Shoulder positioning and the associated peak shoulder loads during propulsion may be important indicators for identifying manual wheelchair users at risk for developing shoulder pain and injury.
