Brief summary

The purpose of this study was to investigate the changes in muscle fatigue and respiratory metabolic energy expenditure during walking with wearable hip-assist robot (V3).

Detailed description

The purpose of this study was to investigate the changes in muscle fatigue and respiratory metabolic energy expenditure during walking with wearable hip-assist robot (V3). Metabolic energy expenditure and muscle fatigue are measured simultaneously.

Interventions

DEVICETreadmill walking

All subjects underwent measurements of muscle fatigue and respiratory metabolism energy during treadmill walking at a comfortable speed for 6 minutes and measured by three conditions (①NoGEMS-free gait, ②Torque off with GEMS, and ③Torque on with GEMS)
