This investigation compared three dimensional upper extremity motion during wheelchair propulsion in persons with 4 levels of spinal cord injury: low paraplegia (n=17), high paraplegia (n=19), C7 tetraplegia (n=16), and C6 tetraplegia (n=17). Upper extremity motion was recorded as subjects manually propelled a wheelchair mounted on a stationary ergometer. For all motions measured, subjects with paraplegia had similar patterns suggesting that the wheelchair backrest adequately stabilizes the trunk in the absence of abdominal musculature. Compared with paraplegic subjects, those with tetraplegia differed primarily in the strategy used to contact the wheel. This was most evident among subjects with C6 tetraplegia who had greater wrist extension and less forearm pronation.
本研究比较了脊髓损伤4个水平的患者在轮椅推进过程中的三维上肢运动：低位截瘫（n = 17）、高位截瘫（n = 19）、C7四肢瘫（n = 16）和C6四肢瘫（n = 17）。当受试者手动推动安装在固定测力计上的轮椅时，记录其上肢运动。对于所测量的所有运动，截瘫患者具有相似的模式，这表明在没有腹部肌肉组织的情况下，轮椅靠背能充分稳定躯干。与截瘫患者相比，四肢瘫患者在接触车轮的策略上主要存在差异。这在C6四肢瘫患者中最为明显，他们的腕部伸展更大，前臂旋前更小。
