Cardiopulmonary function is exceptionally critical during the early stages of rehabilitation after neurological disorders such as stroke, spinal cord injury and Parkinson’s disease. This study aimed to demonstrate how robot-assisted and tilt table exercises affect cardiopulmonary function. In this study, ten healthy young adults performed six combinations of conditions according to robot-assisted mode (on/off), angle of tilt table (20°/60°), and functional electrical stimulation (FES) mode (on/off). Four conditions had FES mode off with combinations of robot-assisted mode (on/off) and tilt angle (20°/60°) and two conditions had robot-assisted mode and FES on with tilt angle (20°/60°). Cardiopulmonary effects (oxygen uptake [VO2], peak oxygen uptake [VO2peak], metabolic energy cost [MET], rate pressure product [RPP], heart rate [HR], maximum heart rate [%HRmax], and minute ventilation [VE]) were compared in each condition. As a result, in the angle and FES mode effect, VO2, VO2peak, MET, RPP, HR, and %HRmax, unlike that for VE, showed major effects in angle. In addition, in the robot-assisted mode and angle effect, when the FES was switched off, VO2, METs, and VE values showed major effects in the robot-assisted mode, whereas all other values showed major effects in angle. Compared to earlier reported findings, we can expect that robot-assisted tilt table training can lead to changes in the cardiopulmonary function.
