The aim of the study was to assess the relationship of spinal cord injury level and duration to peak aerobic capacities during arms-only rowing compared with hybrid Functional Electrical Stimulation (FES)-rowing.
Comparison of peak aerobic capacity (VO2), peak ventilation, peak respiratory exchange ratio, and peak heart rate were measured during arms-only rowing and FES-rowing obtained from graded exercise tests.
Peak aerobic values were strongly related to injury level and injury duration for both arms-only rowing (r = 0.67, P < 0.05) and FES-rowing (r = 0.61, P < 0.05). Peak aerobic capacities were greater across all injury levels and durations with FES-rowing compared with arms-only rowing. Differences in VO2 were inversely related to injury level (r = 0.55, P < 0.05) with greater increases in VO2 in higher level injuries. Injury durations of less than 2 yrs had greater percent increases in VO2 with FES-rowing.
FES-rowing acutely post injury may have the greatest effect to maintain function and improve VO2. This impact seems to be greatest in those with higher level injuries.
本研究旨在评估脊髓损伤水平和时间与仅手臂划桨和混合功能性电刺激（FES）划桨时的峰值有氧能力之间的关系。
通过分级运动试验测量仅手臂划桨和 FES 划桨时的峰值有氧能力（VO2）、峰值通气量、峰值呼吸交换率和峰值心率。
对于仅手臂划桨（r = 0.67，P < 0.05）和 FES 划桨（r = 0.61，P < 0.05），峰值有氧值与损伤水平和损伤持续时间密切相关。与仅手臂划桨相比，所有损伤水平和持续时间的 FES 划桨的峰值有氧能力更高。VO2 的差异与损伤水平呈负相关（r = 0.55，P < 0.05），较高水平的损伤导致 VO2 增加更大。损伤持续时间少于 2 年的患者，FES 划桨时 VO2 的百分比增加更大。
受伤后急性 FES 划桨可能对维持功能和提高 VO2 有最大的影响。这种影响在损伤程度较高的患者中似乎更大。
