Efficacy of MCIMT with Auditory Cueing in order to Augment Functional Motor Recovery of Chronic Hemiparetic Arm
Abstract
Background: Stroke is a leading cause of functional impairments globally, often resulting in long-term disability and a substantial impact on individuals, families, and caregivers. Learned nonuse, a phenomenon where motor deficits persist after a stroke due to central nervous system suppression, is a significant challenge in stroke rehabilitation. Constraint-Induced Movement Therapy (CIMT) is a well-established neurorehabilitation approach based on behavioural training, which includes repetitive task-specific training, behavioural techniques, and constraining the use of the more affected upper extremity. CIMT has been successful in improving functionality in chronic hemiparetic stroke patients, promoting cortical reorganization and neural plasticity.
Method: This study involved 60 stroke survivors aged 20 or older, selected purposively and meeting specific criteria. Participants underwent an 8-week Modified CIMT (M-CIMT) program with auditory cueing for the hemiparetic upper limb. Data collection included pre-test and post-test assessments using the Wolf Motor Function Test (WMFT) and the Motor Activity Log (MAL) to evaluate functional activity. The M-CIMT program comprised warm-up sessions, M-CIMT protocols, and cool-down exercises, conducted five days a week.
Results: Following participation in the M-CIMT program, significant improvements were observed in WMFT and MAL scores. The mean pre-test score of 46.60 seconds decreased to a mean post-test score of 16.85 seconds, with highly significant t-values of 14.292 and -51.356 and a p-value of 0.0, indicating a strong correlation between the two datasets. The analysis revealed that M-CIMT effectively enhanced upper extremity function in chronic stroke patients.
Conclusion: This study highlights the effectiveness of the Modified CIMT protocol, emphasizing repeated use and a distributed practice schedule, in reducing upper-limb impairment and improving upper-limb use and function in chronic stroke patients. The significant improvement in post-test scores underscores the promise of M-CIMT as a valuable approach for upper extremity rehabilitation following chronic stroke, offering hope for enhanced recovery and improved quality of life for affected individuals.
