摘要

Background and Objective.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). Methods. In a pre-post randomized, controlled trial, 30 stroke patients received 2 hours of mCIMT or traditional rehabilitation (TR) for 3 weeks. Motor control of the upper extremity was evaluated using kinematic analysis in unilateral and bilateral tasks. Kinematic variables included spatial and temporal movement efficiency and type of movement control (preplanned control, representing well-learned movement, or feedback-guided control). Functional outcomes were evaluated using the Motor Activity Log (MAL) and the Functional Independence Measure (FIM). Results. Patients receiving mCIMT showed more temporally (P = .013) and spatially (P = .011) efficient movement and more preplanned movement control (P = .009) during the bimanual task, and greater gains in FIM (P = .004) and MAL scores (amount of use: P < .0001, and quality of movement: P = .012) than patients in the TR group. Patients receiving mCIMT produced more ballistic/preplanned reaching movement than did patients receiving TR (P = .023) during the unilateral task; but there were no group differences in temporal or spatial efficiency in unilateral task performance. Conclusions. 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.
