Effects of modified constraint-induced movement therapy on movement kinematics and daily function in patients with stroke: a kinematic study of motor control mechanisms.

Wu CY, Lin KC, Chen HC, Chen IH, Hong WH

Motor control of the upper extremity during unilateral and bimanual functional tasks and functional change during daily activities were evaluated in patients with stroke treated with modified constraint-induced movement therapy (mCIMT). 30 stroke patients received 2 hours of mCIMT or traditional rehabilitation (TR) for 3 weeks. Patients receiving mCIMT showed more temporally and spatially efficient movement and more preplanned movement control during the bimanual task, and greater gains in Functional Independence Measure and Motor Activity Log scores than patients in the TR group. Patients receiving mCIMT produced more ballistic/preplanned reaching movement than did patients receiving TR during the unilateral task; but there were no group differences in temporal or spatial efficiency in unilateral task performance. The authors conclude that relative to TR, mCIMT produced a greater improvement in functional performance and motor control. Improvement of motor control after mCIMT was based on improved spatial and temporal efficiency, apparently more salient during bimanual rather than unilateral task performance. This suggests that bilateral task performance should potentially be emphasized in kinematic study of changes in motor control after mCIMT.
