最近开发了一种功能性电刺激（FES）辅助划船机，以增强脊髓损伤患者的心血管训练。对该机器作为培训工具的功效进行了评估。6名四肢瘫痪患者（C6-T1）和2名截瘫患者（T3-6）连续完成了一系列的三项测试：（1）仅腿部刺激（股四头肌和腿筋组）-“刺激”，（2）仅臂排-“排”和（3）同时行和刺激-“R & S”。记录的测量指标包括摄氧量（VO 2）、每分钟通气量（Ve）、呼吸交换率（RER）、心率（HR）和血压（BP）。此外，8名受试者中有6名参加了定性评估，包括探索受试者对机器和测试的感知的引导性访谈。三次测试之间的VO 2显著增加，R & S产生的平均稳态值为16.34 nm（+/- 0.74）ml/kg/min（最大值的83%）。这些值代表了12%的增长，单独的行。感兴趣的是定性评估显示，受试者认为R & S比行更容易，尽管观察到的VO 2水平较高。结果表明，划船机是一种潜在的有价值的混合训练设备，可以显着降低心血管疾病的风险因素，提高SCI患者的生活质量。
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.
