To determine the magnitude and range of increases in peak aerobic capacity with hybrid-functional electrical stimulation (FES) rowing versus arms-only rowing in persons with spinal cord injury.
Comparison of graded exercise tests for peak responses during FES rowing and arms-only rowing. Preliminary data on adaptations to FES row training were gathered in a subset of individuals.
Outpatient cardiovascular research laboratory.
Six male patients with spinal cord injury (T4-T9, American Spinal Injury Association class A). METHODS OR INTERVENTION: Arms-only rowing was compared with FES rowing, in which the person who is exercising synchronizes the voluntarily controlled upper body movement with the FES-controlled leg movement via stimulation to the paralyzed leg muscles. A subgroup (n = 3) completed at least 6 months of a progressive FES row training exercise program with graded exercise tests every 6 months.
Peak oxygen consumption, peak ventilation, peak respiratory exchange ratio, peak heart rate, and peak oxygen pulse.
Peak oxygen consumption was greater during FES rowing than during arms-only rowing (20.0 ± 1.9 mL/kg/min versus 15.7 ± 1.5 mL/kg/min, P = .01). Peak ventilation was similar, whereas peak respiratory exchange ratio and peak heart rate tended to be lower (P = .14 and P = .19, respectively). As a result, oxygen pulse was greater by 35% during FES rowing. Two of the three persons who completed at least 6 months of FES row training demonstrated increases in aerobic capacity greater than those previously observed in able-bodied individuals.
FES rowing may provide a more robust exercise stimulus for persons with spinal cord injury than most options currently available because of the greater aerobic demand.
确定使用混合功能电刺激（FES）划船与仅手臂划船相比，在脊髓损伤患者中增加峰值有氧能力的幅度和范围。
比较 FES 划船和仅手臂划船时的递增运动试验的峰值反应。在一个亚组个体中收集了关于 FES 划船训练适应的初步数据。
门诊心血管研究实验室。
6 名男性脊髓损伤患者（T4-T9，美国脊髓损伤协会 A 级）。
比较仅手臂划船与 FES 划船，在 FES 划船中，进行锻炼的人通过刺激瘫痪的腿部肌肉来使自主控制的上半身运动与 FES 控制的腿部运动同步。一个亚组（n=3）完成了至少 6 个月的渐进式 FES 划船训练计划，并每 6 个月进行一次递增运动试验。
峰值耗氧量、峰值通气量、峰值呼吸交换率、峰值心率和峰值氧脉搏。
FES 划船时的峰值耗氧量大于仅手臂划船时的峰值耗氧量（20.0±1.9 毫升/公斤/分钟对 15.7±1.5 毫升/公斤/分钟，P=0.01）。峰值通气量相似，而峰值呼吸交换率和峰值心率倾向于较低（分别为 P=0.14 和 P=0.19）。因此，FES 划船时的氧脉冲增加了 35%。完成至少 6 个月 FES 划船训练的 3 人中的 2 人，其有氧能力的增加大于之前在健康个体中观察到的增加。
与大多数现有的选择相比，FES 划船可能为脊髓损伤患者提供更强大的运动刺激，因为它需要更高的有氧能力。
