Cardiopulmonary responses to robotic end-effector-based walking and stair climbing

摘要: Abstract Background A recently developed robotic end-effector device (G-EO system, Reha Technology AG) can simulate walking and stair climbing. This approach has the potential to promote cardiovascular exercise training during rehabilitation. The aim of this study was characterise cardiopulmonary responses end-effector-based in able-bodied subjects evaluate feasibility intensity-guided testing. Methods Five healthy aged 33.7 ± 8.8 years (mean ± SD) performed a constant load test an incremental test. outcome measures were steady-state peak performance parameters including oxygen uptake (VO 2 ) heart rate (HR). Results Passive climbing  = 13.6 ± 4.5 mL/min/kg, HR = 95 ± 23 beats/min) showed considerably lower compared reference data  = 33.5 ± 4.8 mL/min/kg, HR = 159 ± 15 beats/min). Peak testing were: VO  = 35.8 ± 5.1 mL/min/kg HR = 161 ± 27 beats/min, corresponding relative  = 76.0 ± 18.7% predicted aerobic capacity HR = 87.3 ± 14.5% age-predicted HR maximum. Conclusion End-effector-based is promising method for implementation exercise. Although evoked than conventional climbing, active contribution elicited substantial within recommended ranges training.
