This randomized controlled trial aims to evaluate the effects of Fresnel prism glasses on visual perception, balance, gait, and functional independence in post-stroke patients. Stroke survivors, particularly those with right hemisphere involvement, often experience visuospatial deficits such as unilateral spatial neglect, leading to impaired balance, abnormal gait, and reduced functional independence. Fresnel prism glasses offer a low-cost, non-invasive intervention that may improve visuospatial alignment and postural control by modifying visual input. Adult post-stroke patients will be randomly allocated into an intervention group receiving Fresnel prism glasses alongside conventional physical therapy, and a control group receiving conventional therapy alone. Outcome measures will include the Motor-Free Visual Perception Test, Berg Balance Scale, Functional Independence Measure, and JAKC Observational Gait Analysis. Assessments will be conducted at baseline, post-intervention, and follow-up. The study is expected to provide evidence on whether Fresnel prism glasses can serve as an effective adjunct to conventional rehabilitation for improving mobility, balance, and functional outcomes in stroke survivors.
