About

The purpose of this study is to quantify the improvement of post- stroke individuals' ability to move their arms during and after robot assisted therapy.

While researchers know that robot assisted therapies improve motor performance over the course of weeks, they do not know how motor performance is affected over the course of minutes or hours. A better understanding of how robot assisted therapies affect motor performance on short time scales may help us to prescribe more effective therapy doses to maximize motor recovery after neurological injury.

The study will allow us to obtain a detailed understanding of the performance of the device as described above.
