To investigate the association between propulsion biomechanics, including variables that describe smoothness of the applied forces, and shoulder pain in individuals with spinal cord injury (SCI).
Cross-sectional, observational study.
Non-university research institution.
Community dwelling, wheelchair dependent participants (N=30) with chronic paraplegia between T2 and L1, with and without shoulder pain (age, 48.6±9.3y; 83% men).
Not applicable.
Rate of rise and jerk of applied forces during wheelchair propulsion. Participants were stratified in groups with low, moderate, and high pain based on their Wheelchair User Shoulder Pain Index score on the day of measurement.
A mixed-effect multilevel analysis showed that wheelchair users in the high pain group propelled with a significantly greater rate of rise and jerk, measures that describe smoothness of the applied forces, compared with individuals with less or no pain, when controlling for all covariables.
Individuals with severe shoulder pain propelled with less smooth strokes compared to individuals with less or no pain. This supports a possible association between shoulder pain and rate of rise and jerk of the applied forces during wheelchair propulsion.
研究推进生物力学与肩部疼痛之间的关联，包括描述作用力平滑度的变量，以及脊髓损伤（SCI）患者的肩部疼痛。
横断面、观察性研究。
非大学研究机构。
居住在社区、依赖轮椅的慢性截瘫患者（T2 至 L1 之间，有或没有肩部疼痛，年龄 48.6±9.3 岁；83%为男性）。
不适用。
轮椅推进过程中施加力的上升率和急动度。根据当天测量的轮椅使用者肩部疼痛指数（Wheelchair User Shoulder Pain Index）得分，将参与者分为低、中、高疼痛组。
混合效应多级分析显示，与疼痛程度较低或无疼痛的患者相比，高疼痛组的轮椅使用者在控制所有协变量的情况下，施加力的上升率和急动度显著更大，这些指标描述了作用力的平滑度。
与疼痛程度较低或无疼痛的患者相比，严重肩部疼痛的患者推进时的动作不够流畅。这支持了肩部疼痛与轮椅推进过程中施加力的上升率和急动度之间可能存在关联。
