Robot-assisted Gait Rehab Lab

SMC-SAIT Collaborative Research - Wearable Walking-assist Robot Study 

The purpose of this study is to investigate the effect of a wearable walking-assist robot on gait rehabilitation in stroke patients and elderly persons with gait disorder. We used the Gait Enhancing and Motivating System (GEMS), a wearable walking-assist robot, developed by Samsung Advanced Institute of Technology (SAIT, Suwon, Republic of Korea) to deliver  interactive assist of joint motion according to the user’s voluntary efforts during locomotion training.


We have two walking-assist robots, a hip-assist robot (GEMS-H) and an ankle-assist robot (GEMS-A). In order to verify the gait rehabilitation and walking-assist effects of the GEMS, measurement parameters included gait analysis using a 3D-motion capture system, muscle activity pattern and muscle effort analysis using a surface electromyography system (sEMG, 12ch), cardiopulmonary metabolic energy cost analysis using a portable telemetric gas analyzer system (K5), ground reaction force measurement using a forceplate, brain activity measurement using a functional near-infrared spectroscopy (fNIRS) as well as various functional assessments.
