Effect of Gait Training With a Walking Assist Robot on Gait Function and Balance in Elderly Adults

Not Applicable

Completed

• Conditions: Healthy; Gait, Unsteady
• Interventions: Device: Samsung Hip Assist v1

• Registration Number: NCT03325998
• Lead Sponsor: Samsung Medical Center

Brief Summary

The purpose of this study was to investigate the effects of gait training with the new wearable hip assist robot developed by Samsung Advance Institute of Technology (Samsung Electronics Co, Ltd, Korea) in elderly adults.

Detailed Description

Eight elderly adults will participate in this study. All subjects will receive training 3 times per week for 8 weeks for 24 training sessions. Each session is directed by a licensed physical therapist and lasted 60 min (including rest period of 10 min). Brain activity and gait assessment will be performed at visits 0 (baseline), 24 (post-test), and at 3 months (follow-up) after training.

Primary objective is to demonstrate the effects of hip assist robot on spatio-temporal parameters measured by motion capture system (Motion Analysis Corporation, Santa Rosa, CA, USA), muscle activation patterns measured by surface electromyography (sEMG) (Noraxon Inc., Scottsdale, AZ, USA), metabolic energy cost parameters measured by portable cardiopulmonary metabolic system (Cosmed K4B2, Rome, Italy) and cortical activation measured by functional Near-Infrared-Spectroscopy (fNIRS) (NIRScout, NIRx, Germany).

Secondary objective is to demonstrate the effects of hip assist robot on motor function improvement evaluated by Short Physical Performance Battery Protocol and Score Sheet (SPPB), Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Timed Up and Go (TUG) test, Push and Release (P\&R) test, Functional Reach Test (FRT), Korean version Fall Efficacy Scale (K-FES), Manual Muscle Test (MMT) and Range of Motion (ROM).

Arm && Interventions

Group	Intervention	Description
Gait training group	Samsung Hip Assist v1	Gait training with Samsung Hip Assist v1 All subjects receive gait training 3 times per week for 8 weeks for 24 training sessions.

Primary Outcome Measures

Name	Time	Method
Change in 10 meter walk test from baseline in gait speed	session 0 (initial visit); session 24 (at approximately 8 weeks); at 3 months (follow-up)	Measure of self selected speeds by measuring the time it takes an individual to walk 10 meters. To perform the test, patient walks 10 meters (33 ft) and the time is measured when the leading foot crosses the start line and the finish line. The instructions are: "Please walk this distance at your normal pace when I say go."
