Abstract

Background: Stroke remains a leading cause of disability worldwide, with a significant number of survivors experiencing impairments in upper limb function and hand grip strength, which are crucial for performing activities of daily living (ADLs). Understanding the relationship between hand grip strength, functional independence, and arm motor performance is essential for optimizing rehabilitation strategies.


Objective: This study aimed to investigate the impact of hand grip strength on functional independence and arm motor performance in stroke survivors and to evaluate the effectiveness of Mirror Therapy in enhancing these outcomes.


Methods: An analytical cross-sectional study was conducted at DHQ Teaching Hospital Sargodha, involving 22 stroke survivors, evenly split between genders. Participants were aged 45-65 years, clinically diagnosed with ischemic stroke in the subacute stage, and exhibited Modified Ashworth Scale scores of 1 to 1+ for hand flexors. The study employed randomized assignments to intervention groups, utilizing assessments such as the Action Research Arm Test (ARAT), Fugl-Meyer Assessment for Upper Extremity (FMA UE), Hand-Held Dynamometer (HHD), and Stroke Impact Scale (SIS) at baseline, 3 weeks, and 6 weeks. Statistical analysis was performed using Pearson’s coefficient of correlation with SPSS version 25.


Results: Significant improvements were observed in upper limb strength and hand dexterity, particularly in the group undergoing Mirror Therapy. The correlation coefficients among ARAT, HHD, and SIS were .676**, .748**, and .704** respectively, indicating strong positive relationships between hand grip strength, functional ability, and quality of life. Mirror Therapy demonstrated notable enhancements in ARAT (p = .001), FMA UE (p < .000), HHD (p = .000), and SIS scores (p = .000), reflecting increased functional ability, grip strength, and improved quality of life.


Conclusion: The study confirmed the significant impact of hand grip strength on the functional independence and arm motor performance of stroke survivors, with Mirror Therapy providing substantial benefits. These findings advocate for the inclusion of grip strength-focused interventions and Mirror Therapy in stroke rehabilitation programs to improve survivors' functional outcomes and quality of life.
