Cognition as a moderator of motor learning post-stroke

Purpose

The goal of this study is to understand how an individual’s cognitive function and brain structure may influence their ability to learn a new walking pattern. We hope to learn how people can best learn a new walking pattern when parts of the brain are damaged and cognitive function may be impaired.

We are looking for survivors of stroke, 6 months or more after their stroke, who can walk on a treadmill for at least 5 minutes.

About This Study

As many as 70% of older adults with chronic stroke have post-stroke cognitive impairment. Our study aims to assess the impact of post-stroke cognitive impairment on motor learning during walking. With this information, we hope to help guide rehabilitation and individually tailor treatments to improve walking function in those with chronic stroke.
