Objectives. To quantify the association between performance-based manual wheelchair propulsion tests (20 m propulsion test, slalom test, and 6 min propulsion test), trunk and upper extremity (U/E) strength, and seated reaching capability and to establish which ones of these variables best predict performance at these tests. Methods. 15 individuals with a spinal cord injury (SCI) performed the three wheelchair propulsion tests prior to discharge from inpatient SCI rehabilitation. Trunk and U/E strength and seated reaching capability with unilateral hand support were also measured. Bivariate correlation and multiple linear regression analyses allowed determining the best determinants and predictors, respectively. Results. The performance at the three tests was moderately or strongly correlated with anterior and lateral flexion trunk strength, anterior seated reaching distance, and the shoulder, elbow, and handgrip strength measures. Shoulder adductor strength-weakest side explained 53% of the variance on the 20-meter propulsion test-maximum velocity. Shoulder adductor strength-strongest side and forward seated reaching distance explained 71% of the variance on the slalom test. Handgrip strength explained 52% of the variance on the 6-minute propulsion test. Conclusion. Performance at the manual wheelchair propulsion tests is explained by a combination of factors that should be considered in rehabilitation.
目的。量化基于表现的手动轮椅推进测试（20米推进测试、障碍滑雪测试和6分钟推进测试）、躯干和上肢（U/E）力量以及坐位伸展能力之间的关联，并确定这些变量中哪些最能预测这些测试的表现。方法。15名脊髓损伤（SCI）患者在从住院SCI康复出院前进行了三项轮椅推进测试。还测量了躯干和U/E力量以及单侧手支撑的坐位伸展能力。双变量相关性分析和多元线性回归分析分别用于确定最佳决定因素和预测因素。结果。三项测试的表现与前屈和侧屈躯干力量、前坐位伸展距离以及肩部、肘部和握力测量值呈中度或强相关性。最弱侧肩部内收肌力量解释了20米推进测试最大速度53%的方差。最强侧肩部内收肌力量和前坐位伸展距离解释了障碍滑雪测试71%的方差。握力解释了6分钟推进测试52%的方差。结论。手动轮椅推进测试的表现由康复中应考虑的多种因素共同解释。
