Recently a FES (functional electrical stimulation)-assisted rowing machine was developed to enhance cardiovascular training in people with spinal cord injuries. The machine was assessed in terms of its efficacy as a training tool. Six patients who were quadriplegic (C6-T1) and 2 who were paraplegic (T3-6) completed a series of three tests in succession: (1) leg stimulation only (quadriceps and hamstring groups)--'Stim', (2) arm row only--'Row' and (3) simultaneous row and stimulation--'R & S'. Measurements recorded included oxygen uptake (VO2), minute ventilation (Ve), respiratory exchange ratio (RER), heart rate (HR) and blood pressure (BP). In addition, 6 out of the 8 subjects took part in a qualitative assessment comprising a guided interview exploring the subject's perception of the machine and test. Significant increases in VO2 were demonstrated between the three tests with R & S producing mean steady-state values of 16.34 nm (+/- 0.74) ml/kg/min (83% of maximum). These values represented a 12% increase over Row alone. Of interest was the qualitative assessment which revealed that subjects perceived R & S to be easier than Row despite the higher levels of VO2 observed. The results suggest that the rowing machine represents a potentially valuable hybrid training device that may significantly reduce risk factors for cardiovascular disease and improve the quality of life of people with SCI.
最近，一种功能性电刺激（FES）辅助划船机被开发出来，用于增强脊髓损伤患者的心血管训练。该机器作为一种训练工具的功效得到了评估。6名四肢瘫痪（C6 - T1）患者和2名截瘫（T3 - 6）患者连续完成了一系列三项测试：（1）仅腿部刺激（股四头肌和腘绳肌群）——“刺激”，（2）仅手臂划船——“划船”，以及（3）同时划船和刺激——“划船与刺激”。记录的测量指标包括摄氧量（VO2）、分钟通气量（Ve）、呼吸交换率（RER）、心率（HR）和血压（BP）。此外，8名受试者中有6人参与了一项定性评估，该评估包括一次引导性访谈，探讨受试者对该机器和测试的看法。在三项测试之间，VO2有显著增加，“划船与刺激”产生的平均稳态值为16.34（±0.74）ml/kg/min（为最大值的83%）。这些值比仅“划船”时增加了12%。有趣的是定性评估结果显示，尽管观察到“划船与刺激”时VO2水平较高，但受试者认为它比“划船”更容易。结果表明，划船机是一种潜在有价值的混合训练设备，可能会显著降低心血管疾病的风险因素，并改善脊髓损伤患者的生活质量。
