Samsung Medical Center54 enrolled

Overview

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).

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.

Outcomes

Primary Outcomes

Change on metabolic energy expenditure

All subjects underwent measurements of 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). Metabolic energy expenditure and muscle fatigue are measured simultaneously

Time frame: 1 hour

Secondary Outcomes

Change on muscle fatigue

All subjects underwent measurements of muscle fatigue at a comfortable speed for 6 minutes and measured by three conditions (①NoGEMS-free gait, ②Torque off with GEMS, and ③Torque on with GEMS). Metabolic energy expenditure and muscle fatigue are measured simultaneously

Time frame: 1 hour
