About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Elderly adults over age 65
  • Those without a history of central nervous system disease

Exclusion criteria

  • Those who have problems with walking due to problems such as visual field defects or fractures
  • A person whose height is less than 140 cm or not more than 185 cm
  • Body mass index BMI (body mass index) based on 35 or more obese
  • Those with a cognitive problem that are difficult to understand and participate fully in this study
  • Those who are at risk of falling when walking with serious dizziness

Treatment and study plan

Treadmill walking

Device

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)

Primary outcomes

  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 outcomes

  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
