Current motor control issues in stroke rehabilitation.

The science of motor control provides dynamic and intriguing study for practical problems of concern to neurorehabilitation specialists. Two areas of present interest and controversy in stroke rehabilitation are addressed in this issue of NeuroRehabilitation. Section I of this jou'rnal will highlight current issues on the controversies of strengthening spastic muscle and forced-limb usage as therapeutic interventions. Section II is devoted to the topic of motor control differences following right vs. left neurologic lesions. Both of these content areas represent current scientific debate in motor control science. I hope the readers of NeuroRehabilitation find this collection of scholarly works interesting and thought provoking. To begin Section I: 'Strengthening and Forced-Limb Usage', Dr. Daniel Bourbonnais et al. present a case study demonstrating a particular type of strengthening model for motor reeducation. Based on the hypothesis that feedback on torque patterns will build strength and coordination for functional upper extremity control, Bour-
