背景：手动轮椅推进过程中的肩部负荷导致脊髓损伤(SCI)患者肩部疼痛的发生。目的：采用回归分析的方法，研究截瘫患者在WCP过程中手接触角(初始接触时手在推轮缘上的位置和在WCP周期推进阶段的释放)与WCP的推进特性、推轮力和肩部动力学的关系。方法：收集222例(男性198例，女性24例)截瘫患者的生物力学数据。研究对象的平均年龄为34.7岁(±9.3)岁，平均发病时间为9.3年(±6.1岁)，平均体重为74.4公斤(±15.9公斤)。结果：推力弧度增大(平均75.3°)与速度增大(R=0.384，P<0.001)、周期距离增大(R=0.658，P<0.001)、节律减慢(R=-0.419，P<0.001)有关。
BACKGROUND: Shoulder loading during manual wheelchair propulsion (WCP) contributes to the development of shoulder pain in individuals with spinal cord injury (SCI).OBJECTIVE: To use regression analysis to investigate the relationships between the hand contact angle (location of the hand on the pushrim at initial contact and release during the push phase of the WCP cycle) with propulsion characteristics, pushrim forces, and shoulder kinetics during WCP in individuals with paraplegia.METHODS: Biomechanical data were collected from 222 individuals (198 men and 24 women) with paraplegia from SCI during WCP on a stationary ergometer at a self-selected speed. The average age of participants was 34.7 years (±9.3), mean time since SCI was 9.3 years (±6.1), and average body weight was 74.4 kg (±15.9). The majority (n = 127; 56%) of participants had lower level paraplegia (T8 to L5) and 95 (42%) had high paraplegia (T2 to T7).RESULTS: Increased push arc (mean = 75.3°) was associated with greater velocity (R = 0.384, P < .001) and cycle distance (R = 0.658, P < .001) and reduced cadence (R = -0.419, P
