Summary

The purpose of this study was to investigate the effects of the new wearable hip assist robot, gait enhancing and motivating system (GEMS) developed by Samsung Advanced Institute of Technology (Samsung Electronics Co, Ltd., Korea) on gait, sit-to-stand movement and cortical activation in elderly adults and stroke patients.

Detailed description

In elderly adults, 1. Spatio temporal characteristics, muscle activation and foot pressure distribution are measured by motion capture system (Motion Analysis Corporation, Santa Rosa, CA, USA), surface electromyography (sEMG) (Noraxon Inc., Scottsdale, AZ, USA) and F-Scan Mobile system (Tekscan Inc., South Boston, MA, USA) during 10m walking test. 2. Muscle activation and foot pressure distribution are measured by surface electromyography (sEMG) and F-Scan Mobile system during five times sit-to-stand test. 3. Muscle activation and foot pressure distribution are measured by surface electromyography (sEMG) and F-Scan Mobile system during stair climbing. 4. Cortical activation is measured by functional Near-Infrared-Spectroscopy (fNIRS) (NIRScout, NIRx, Germany) during treadmill gait. In stroke patients, 1. Muscle activation and foot pressure distribution are measured by surface electromyography (sEMG) and F-Scan Mobile system during five times sit-to-stand test. 2. Cortical activation is measured by functional Near-Infrared-Spectroscopy (fNIRS) (NIRScout, NIRx, Germany) during treadmill gait.
