Overview

Rehabilitation interventions commonly used for stroke survivors include task-specific training, balance and strength exercises, and the use of assistive devices to enhance mobility and independence. Advanced technologies, such as body-weight-supported treadmill systems and robotic devices, may be employed when appropriate. Current rehabilitation therapies for stroke survivors are moderately effective with a limited effect size, especially in stroke survivors with severe impairment. Novel therapies, such as transcutaneous spinal cord stimulation (tSCS), may further improve outcomes in the target population. This pilot study will allow us to examine the feasibility and gather pilot data on a combined intervention of assistive gait training and tSCS in non-ambulatory stroke survivors.

Robot-assisted gait training and transcutaneous spinal cord stimulation in chronic non-ambulatory stroke survivors: pilot RCT trialDEVICE

Participants in the experimental group will receive 30 minutes of robot assisted gait training (RAGT) transcutaneous spinal cord stimulation 3 times per week, 8 weeks, totaling 24 sessions. The gait training will utilize a treadmill equipped with a partial-body-weight support system and a lab-developed RAGT device. The RAGT protocol will be the same as in the control group

Robot assisted gait training aloneDEVICE

Participants in the control group will receive 30 minutes of assisted gait training (RAGT), 3 times per week, for 8 weeks, totaling 24 sessions. The gait training will utilize a treadmill equipped with a partial-body-weight support system and a lab-developed RAGT device

Outcomes

Primary Outcomes

Cardiac Output (Measured by Impedance Cardiography - BIOPAC MP160 System)

Cardiac output (L/min) will be measured using an impedance cardiography system (MP160, BIOPAC Systems Inc., Goleta, California). Measurements will be done during a 6-minute walk test. Data collection for each participant will occur at approximately the same time of day (between 9:00 AM and 11:00 AM) before the first intervention session and after completion of the 24th intervention session.

Time frame: Before and after 24 training sessions (8 weeks)
