Arm Intervention/treatment
Experimental: Treadmill 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)
 Device: Treadmill 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)


Outcome Measures

Primary Outcome Measures :
  1. Change on metabolic energy expenditure [ Time Frame: 1 hour ]

    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



Secondary Outcome Measures :
  1. Change on muscle fatigue [ Time Frame: 1 hour ]

    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
