Context Reorganization in central motor networks occurs during early recovery from hemiparetic stroke. In chronic stroke survivors, specific rehabilitation therapy can improve upper extremity function.Objective To test the hypothesis that in patients who have chronic motor impairment following stroke, specific rehabilitation therapy that improves arm function is associated with reorganization of cortical networks.Design, Setting, and Patients A randomized controlled clinical trial conducted in a US ambulatory rehabilitation program with 21 patients (median [IQR], 50.3 [34.8-77.3] months after unilateral stroke). Data were collected between 2001 and 2004.Interventions Patients were randomly assigned to bilateral arm training with rhythmic auditory cueing (BATRAC) (n=9) or standardized dose-matched therapeutic exercises (DMTE) (n=12). Both were conducted for 1 hour, 3 times a week, for 6 weeks.Main Outcome Measures Within 2 weeks before and after the intervention, brain activation during elbow movement assessed by functional magnetic resonance imaging (fMRI) and functional outcome assessed using arm function scores.Results Patients in the BATRAC group but not in the DMTE group increased hemispheric activation during paretic arm movement (P=.03). Changes in activation were observed in the contralesional cerebrum and ipsilesional cerebellum (P=.009). BATRAC was associated with significant increases in activation in precentral (P
