Operant Conditioning of Reflex Pathways to Improve Walking in Individuals Post-stroke
The purpose of this study is to examine the changes in reflex pathways in the paretic ankle plantarflexors in individuals with post-stroke hemiparesis using operant conditioning. We are recruiting 5 individuals with chronic post-stroke hemiparesis with foot drop in the affected leg to participate in the reflex training procedure. The study involves 40 visits with a total study duration of about 4 months.
• At least 6 months following a single, unilateral stroke, resulting in hemiparesis.
• Ambulatory with or without assistive device, but must demonstrate a gait deficit which is indicative of foot drop from reduced activation of the tibialis anterior muscle.
• Able to follow verbal directions.
• Able to see icons on computer monitor (with or without corrective lenses) from at least 4 feet away.
• All subjects will be adults at least 18 years old.
• Know history and current medication management for lower limb spasticity, if any.
