Comparative Efficacy of Constrained Induced Movement Therapy and Motor-Relearning Program in Post Stroke Upper Extremity Function

Abstract

Background: Stroke often leads to significant impairments in motor function, particularly in the upper extremities. Constraint-Induced Movement Therapy (CIMT) and Motor Relearning Program (MRP) are two rehabilitation approaches that have shown potential in addressing these deficits. This study aimed to compare the effectiveness of these two therapies in improving upper extremity function in post-stroke hemiplegia. Objective: To evaluate and compare the efficacy of CIMT and MRP in enhancing motor recovery and functional performance of the upper extremity in patients with post-stroke hemiplegia. Methods: This randomized controlled trial included patients aged 35-60 years diagnosed with ischemic or hemorrhagic stroke, confirmed by CT scans and MRI. Patients were randomly assigned to either the CIMT group or the MRP group, each comprising 16 participants. Both groups underwent respective therapies for two hours daily, six days a week, for four weeks. The Motor Assessment Scale and the Functional Independence Measure (FIM) Scale were employed for pre-, post-, and follow-up evaluations. Results: Both groups showed significant improvements in motor function and daily living activities. The CIMT group exhibited greater advancements, with notable increases in upper extremity strength and active range of motion in the shoulder, elbow, and wrist joints. Quantitative improvements in the CIMT group included an average increase of 2 points in Motor Assessment Scale scores and a 15% improvement in FIM scores. The MRP group demonstrated an average increase of 1.5 points in Motor Assessment Scale scores and a 10% improvement in FIM scores. Conclusion: While both CIMT and MRP are effective in improving motor function and daily living activities in patients with post-stroke hemiplegia, CIMT showed a slight edge in enhancing upper extremity strength and range of motion. These findings suggest that CIMT could be a more efficacious approach in the rehabilitation of upper extremity function in stroke patients.
