Predicting Ipsilesional Motor Deficits in Stroke with Dynamic Dominance Model


Some stroke patients have severe weakness in one arm and must rely on their less-affected arm for daily activities. Previous research has shown that in some patients, the less-affected arm also experiences weakness due to the stroke. This research is being done to find out if the less-affected arm can be trained to perform faster and better during daily activities. Approximately 180 people will take part in this research study at Hershey Medical Center and University of Southern California.
