Eight nonimpaired subjects participated in a wheelchair exercise test using a motor-driven treadmill in order to study the effect of rear wheel camber on wheelchair ambulation. The test consisted of four runs with rear wheels in 0, 3, 6, and 9 degrees camber at four speed steps of 2, 3, 4, and 5 km/hr. There were no significant effects upon oxygen cost, heart rate, and mechanical efficiency. The kinematic parameters of push time, push angle, and abduction showed differences between 3 and 6 degrees camber. The relationship between the findings, using surface EMG results for six shoulder muscles, is discussed. For one subject, data were extended to study the angular velocities of shoulder and elbow.
八名身体无损伤的受试者参与了一项使用电动跑步机的轮椅运动测试，以研究后轮外倾角对轮椅行走的影响。该测试包括四轮，后轮外倾角分别为0度、3度、6度和9度，速度分为2、3、4和5公里/小时四个级别。在氧气消耗、心率和机械效率方面没有显著影响。推轮椅时间、推轮椅角度和外展的运动学参数在3度和6度外倾角之间存在差异。讨论了利用六块肩部肌肉的表面肌电图结果得出的研究结果之间的关系。对于一名受试者，数据被扩展以研究肩部和肘部的角速度。
