This study aims to find out what effect there is on the difference in energy use efficiency and gait analysis when walking while wearing knee and hip assist robots based on flexible power structures for normal people. Energy consumption efficiency will measure the amount of energy metabolism and heart rate during walking for a set period of time, and for gait analysis, kinetic and kinematic data will be analyzed through 3D motion analysis. In addition, after completing the evaluation, we intend to help in future improvement of the product by collecting usability and satisfaction evaluation and improvements through questionnaires.

| EXO On, EXO Off, EXO Removed treadmill (Uphill_incline 10°) walking and simultaneous evaluation | Device | - After filling out the consent form for 10 subjects who meet the selection criteria, a total of three evaluations are conducted: one pre-evaluation and one post-evaluation for the knee assist robot and hip assist robot. Pre-evaluation: Evaluation simultaneously with walking on an inclined treadmill (Uphill_incline 10°) for 5 minutes without wearing knee and hip assist robots (speed 1.5 m/s). |
