Effect of Wearable Hip-Assist Robot on Reduction of Cardiopulmonary Metabolic Efficiency in Healthy Adults

Study Overview
=================
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.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | 1 hour | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | 1 hour |
