Spinal Plasticity to Enhance Motor Retraining After Stroke

Stroke is a leading cause of serious long-term disability in the United States with 795,000 individuals suffering a new or recurrent stroke each year. In most cases, disability is associated with incomplete motor recovery of the paretic limb. Full recovery is often not achieved, creating a need for neuromodulation strategies that target the physiological mechanisms impaired by stroke to fully harness the adaptive capacity of the nervous system. The neuromodulation protocol that will be tested in these experiments will target connections between the brain and spinal cord with noninvasive stimulation to enhance movement potential of the hand. Individuals who experienced a single stroke at least 6 months ago may be eligible to participate.
