Effects of Soft Robotic Exosuit on Exercise Capacity, Biomakers of Neuroplasticity, and Motor Learning After Stroke

Detailed Summary

High intensity exercise is known to improve a person's ability to learn new motor skills. The goal of this project is to evaluate if a robotic exosuit can help people who have had a stroke perform walking rehabilitation at higher intensities than they are able to without the exosuit. The investigators will measure exercise training intensity, biomarkers of neuroplasticity (e.g., brain-derived neurotrophic factor; BDNF), and motor learning when people poststroke exercise with and without the exosuit. For this protocol, exosuits developed in collaboration with ReWalk™ Robotics will be used. Aim 1: Determine the effects of a soft robotic exosuit on gait training intensity and serum BDNF in persons post-stroke completing a single bout of high intensity walking. Hypothesis 1: Exosuits will allow individuals post-stroke to (i) walk at higher intensities or (ii) walk at a high intensity for longer durations. Hypothesis 2: Training at a higher intensity, or training at high intensity for longer durations, will result in increased serum BDNF. Aim 2: Determine the effects of a soft robotic exosuit on gait biomechanics measured after a single bout of high intensity walking with versus without a soft robotic exosuit. Hypothesis 3: A single bout of high intensity walking with an exosuit will lead to demonstrably better gait biomechanics than a single bout of high intensity exercise without an exosuit.
