Effectiveness of a Home-Based Leg Exercise Device for Improving Lower-Limb Function Among Stroke Survivors in Thailand: A Quasi-Experimental Study

Le résumé fourni par la source

Stroke is a leading cause of long-term disability, with lower-limb weakness limiting mobility, independence, and quality of life among survivors. Limited access to sustained home-based rehabilitation, particularly in resource-constrained settings, underscores the need for practical, accessible interventions. This study evaluated the effectiveness of a home-based leg exercise device in improving lower-limb function among stroke survivors in Thailand. A quasi-experimental, repeated-measures design was conducted with 64 stroke survivors divided into two groups: an intervention group (n=32) and a control group (n=32). The intervention group engaged in a 12-week home-based rehabilitation program using a leg exercise device, while the control group received standard lower-limb exercises and a self-exercise manual. Outcomes, including lower-limb muscle strength, range of motion (ROM), and activities of daily living (ADL), were measured at baseline and at 1-, 2-, and 3-month follow-ups. Data were analyzed using repeated measures analysis of variance. Results demonstrated that the intervention group showed significantly greater improvements in lower-limb muscle strength compared with the control group throughout the 12 weeks (P < 0.05). Significant improvements were also observed in hip flexion and knee flexion ROM (P < 0.05), whereas hip extension and abduction showed no significant differences. ADL scores significantly improved in the intervention group at the 2- and 3-month follow-ups compared with the control group (P < 0.05). The home-based leg exercise device significantly improved lower-limb muscle strength, joint mobility, and functional ability among stroke survivors. This low-cost intervention may support community-based rehabilitation and promote functional independence, particularly in resource-limited settings.
