Cardiorespiratory fitness assessment with leg cycle exercise testing may be influenced by motor impairments in the paretic lower extremity. Hence, this study examined the usefulness of a unilateral arm crank exercise test to assess cardiorespiratory fitness in individuals with stroke, including sixteen individuals with hemiparetic stroke (mean ± SD age, 56.4 ± 7.5 years) and 12 age- and sex-matched healthy controls. Participants performed the unilateral arm crank and leg cycle exercise tests to measure oxygen consumption ([Formula: see text]O) and heart rate at peak exercise. The [Formula: see text]O at peak exercise during the unilateral arm crank exercise test was significantly lower in the stroke group than in the control group ( < 0.001). In the stroke group, the heart rate at peak exercise during the unilateral arm crank exercise test did not significantly correlate with the Brunnstrom recovery stages of the lower extremity ( = 0.137), whereas there was a significant correlation during the leg cycle exercise test (rho = 0.775, < 0.001). The unilateral arm crank exercise test can detect the deterioration of cardiorespiratory fitness independently of lower extremity motor impairment severity in individuals with hemiparetic stroke. This study is registered with UMIN000014733.
使用腿部循环运动测试进行心肺功能评估可能会受到瘫痪下肢运动障碍的影响。因此，本研究探讨了单侧手臂曲柄运动测试在评估中风患者心肺功能方面的有用性，包括 16 名偏瘫中风患者（平均 ± 标准差年龄，56.4 ± 7.5 岁）和 12 名年龄和性别匹配的健康对照者。参与者进行了单侧手臂曲柄和腿部循环运动测试，以测量峰值运动时的耗氧量（[Formula: see text]O）和心率。与对照组相比，单侧手臂曲柄运动测试时中风组的峰值运动 [Formula: see text]O 明显降低（<0.001）。在中风组中，单侧手臂曲柄运动测试时的峰值运动心率与下肢的 Brunnstrom 恢复阶段没有显著相关性（=0.137），而在腿部循环运动测试时则有显著相关性（rho=0.775，<0.001）。单侧手臂曲柄运动测试可以检测到偏瘫中风患者心肺功能的恶化，而与下肢运动障碍严重程度无关。本研究在 UMIN000014733 注册。
