Intensity Modulated Exoskeleton Gait Training Post Stroke

Stroke is a leading cause of long-term disability. While major advances have been made in early intervention for the treatment of patients post stroke, the majority of survivors have residual mobility challenges. Recovery of motor function is dependent on the interrelationship between dosing, intensity, and task specific practice applied during rehabilitation. Robotic exoskeleton (RE) based gait training utilizes progressive repetitive task-oriented movements to promote functional recovery. The purpose of this investigation was to demonstrate the utilization of intensity modulated exoskeleton gait training on functional outcomes and walking speed post stoke. Preliminary data is presented for individuals diagnosed with stroke who received RE gait training. The intensity modulated RE gait training was delivered by a physical therapist and participants trained at 75-85% of calculated max heart rates at each session, over 10 weeks (30 sessions). After 10 weeks of training participants increased walking speed (10 meter walk test) and functional measures (timed up and go, berg balance assessment, dynamic gait index and functional ambulation category). These preliminary results demonstrate the utilization of intensity modulated gait training for improved functional ambulation and motor recovery using a robotic exoskeleton overground gait training post stroke.
