Neuroimaging Identifies Patients Most Likely to Respond to a Restorative Stroke Therapy

Patient heterogeneity reduces statistical power in clinical trials of restorative therapies. Valid predictors of treatment responsiveness are needed, and several have been studied with a focus on corticospinal tract (CST) injury. We studied performance of 4 such measures for predicting behavioral gains in response to motor training therapy.Patients with subacute-chronic hemiparetic stroke (n=47) received standardized arm motor therapy, and...
