Clinical Trial Summary

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.

• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• 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.

Exclusion Criteria:

• No history of ear disease or balance problems outside of those caused by the stroke.
• Cerebellar stroke
• No other neurological disease or injuries other than the stroke affecting the use of the legs and/or walking.

• Foot Drop
• Paresis
• Peroneal Neuropathies
• Post-stroke Hemiparesis
• Stroke

Intervention

Behavioral:
• Operant conditioning
In this training, individuals with post-stroke hemiparesis are trained to increase the amount of reciprocal inhibition in their paretic leg. By increasing the amount of reciprocal inhibition, the paretic ankle in people post-stroke may exhibit less foot drop.
