Effect of Optokinetic Stimulation on Spatial Neglect and Postural Stability in Patients With Stroke
Sponsor: Cairo University
Summary
The purpose of this study is to investigate the efficacy of optokinetic stimulation in stroke patients by examining its effects on spatial neglect, static balance, dynamic balance, and weight-bearing symmetry.

Conditions
Interventions
Optokinetic stimulation
Patients will receive optokinetic stimulation (OKS) as an intervention for spatial neglect, based on observing moving visual stimuli to promote visual scanning of the neglected hemispace. With the patient properly positioned, the physiotherapist will apply virtual reality glasses supported by a mobile device displaying pre-prepared OKS videos. The videos will show vertical bars moving leftward at a fixed speed of 1 cm/s, with random color changes to maintain attention. Patients will be instructed to report each color change. OKS will be delivered in five 4-minute bouts separated by 1-minute rest intervals, totaling 20 minutes per session.
Sham optokinetic stimulation
A static image consisting of black-and-white vertical bars will be projected for patients in this group. The bars will undergo random color changes similar to those used in the intervention group; however, no movement will be present.
Traditional therapy
All participants in both groups will receive a selected physical therapy program for 30 min per session to enhance balance for 10 weeks.
