Brief summary
The purpose of this study was to investigate the effect of a long-term exercise program using a wearable exoskeleton robot (EX1) on muscular strength in healthy adults aged 19 to under 65 years, compared to an exercise program without EX1.
Interventions
DEVICEWearable Hip Assist Robot(EX1)
EX1 is a hip-type assist device developed by Samsung Electronics.
BEHAVIORALExercise Program 1
Exercise program 1 for fast walking by applying resistance and assist mode of EX1
BEHAVIORALExercise Program 2
Exercise program 2 for normal walking by applying resistance and assist mode of EX1
DEVICEWithout Wearable Hip Assist Robot(EX1)
Overground walking without EX1

Inclusion criteria
* Healthy adults aged 19 to less than 65 years without a history of central nervous system disease
Exclusion criteria
* Those who have difficulty walking independently due to problems such as visual field defects or fractures * Those who have difficulty participating in exercise programs due to adult diseases such as uncontrolled hypertension and diabetes * Those who are at risk of falling while walking due to severe dizziness * Those who are less than 140 cm or more than 185 cm in height that is not suitable size for the wearing of the walking assistance robot * Those who are overweight based on body mass index (BMI) 35 or higher
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change on gait function (muscle activation) | Session 0 (initial visit); after session 18 (at approximately 6 weeks) | All subjects perform overground walking to assess the change of muscle activation after the interventions using a surface EMG (6 channels). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in heart rate | Every session (total 18 sessions/ 30 minutes) | All subjects are measured for heart rate during the intervention. |
| Reduction in stress level | Session 0 (initial visit); after session 18 (at approximately 6 weeks) | We evaluate the subject's usual stress level through a questionnaire. The Perceived Stress Scale (PSS-10) is a 10-item questionnaire originally developed by Cohen et al. (1983) widely used to assess stress levels in young people and adults. The questions ask about feelings and thoughts during the last month. In each case, respondents are asked how often they felt a certain way on a five-point scale from 'never' to 'very often'. Answers are then scored as follow: Never = 0; Almost never = 1; Sometimes = 2; Fairly often = 3; Very often = 4. The PSS score is then obtained by summing across all items. Higher scores indicate higher levels of perceived stress. |
| Reduction in body fat percentage | Session 0 (initial visit); after session 18 (at approximately 6 weeks) | All subjects are measured for body fat before and after the intervention. |
| User Satisfaction Questionnaire | After session 18 (at approximately 6 weeks) | We evaluate the satisfaction questionnaire for EX1 use and exercise program. |
| Change on gait function (kinematic) | Session 0 (initial visit); after session 18 (at approximately 6 weeks) | All subjects perform overground walking to assess the change of kinematic using a motion analysis. |
