This study has two interventional components, the first is a cross-over design and the second is a randomized control trial. Both will evaluate the effectiveness of transcutaneous (non-invasive) spinal cord stimulation on gait and balance function for individuals with hemiplegia due to stroke.
OBJECTIVES: * Exploratory phase: Identify a systematic, methodical approach to identifying the optimal stimulation parameters and gait training protocol for each individual patient with stroke. * Aim 1: Evaluate short-term effects of transcutaneous spinal cord stimulation + gait training on gait symmetry, gait performance, and corticospinal circuitry in individuals with chronic stroke. * Aim 2: Evaluate and predict long-term effects of transcutaneous spinal cord stimulation + gait training on gait symmetry, gait performance, and corticospinal circuitry in individuals with chronic stroke * Aim…
Inclusion Criteria * Age 18 years or older * Able and willing to give written consent and comply with study procedures * At least 6 months' post-stroke * Hemiplegia secondary to a single stroke * Functional Ambulation Category of 2 or greater - i.e., subject needs continuous or intermittent support of one person to help with balance and coordination. * Not currently receiving regular physical therapy services * Physician approval to participate Exclusion Criteria * Ataxia * Multiple stroke history * Botox injection in lower extremity within the last 4 months * Modified Ashworth score of 3 o…
Transcutaneous Spinal Cord Neurostimulator will deliver transcutaneous electrical spinal cord stimulation while subjects perform lower limb locomotor activities.
Subjects will receive lower limb locomotion training without transcutaneous spinal cord stimulation. However, the amount of time spent in side-lying locomotion training, treadmill training and over ground training will depend on individual tolerance and progression.
Subjects may receive various lower limb locomotion training with or without transcutaneous spinal cord stimulation. Training approaches may include but are not limited to single or split belt treadmill and over ground walking. Transcutaneous Spinal Cord Neurostimulator may deliver a variety of transcutaneous electrical spinal cord stimulation to subjects.
