Comparative Effects of Mirror Therapy and Constraint-induced Movement Therapy on Grip Strength, Hand Dexterity, and Upper Limb Motor Function in Post-stroke Patients.

This randomized clinical trial aims to evaluate and compare the effects of Mirror Therapy (MT) and Constraint-Induced Movement Therapy (CIMT) on grip strength, hand dexterity, and upper limb motor function in post-stroke patients. Stroke is a leading cause of long-term disability, particularly affecting upper limb motor function, which severely impacts the ability to perform daily activities. This study seeks to provide insights into which approach or combination of therapies is more effective in improving upper limb functionality in post-stroke patients, thereby enhancing their quality of life and rehabilitation outcomes.

In this study, a randomized clinical trial (RCT) methodology will be utilized. 32 participants male and female patients aged 40 years and above who have a confirmed diagnosis of stroke, verified through CT scan and MRI imaging will be included. Eligible participants will have experienced a stroke within the past six months to ensure relevance to the intervention and recovery phase. Additionally, only those with a Brunnstrom grade of 2 or higher, indicating some degree of voluntary motor function, will be included by using non-probability convenience sampling and randomly divided into two groups: one receiving only CIMT and the other combining MT with CIMT. Baseline measurements will be taken for all participants to assess grip strength, hand dexterity, and upper limb motor function, utilizing validated tools like the Fugl-Meyer Assessment (FMA), Motor Activity Log (MAL), Box and Block Test (BBT), and Hand-Held Dynamometer. Both groups will undergo therapy sessions five days a week for six weeks, with daily sessions lasting 60-90 minutes. The data analysis will be performed using SPSS version 25. Data normality will be checked via the Shapiro-Wilk test. To evaluate within-group changes between pre- and post-treatment measurements, the Wilcoxon signed-rank test will be used, as it is appropriate for non-parametric data. The Mann-Whitney U test, a non-parametric test for comparing two independent groups.
