Effects of Gaze Stabilization Training on Dynamic Visual Acuity and Balance in Patients with Stroke

Purpose This study investigated the effects of gaze stabilization training on dynamic visual acuity and balance in patients with stroke. Methods Twentyfour patients with post stroke hemiplegia were randomly assigned to an experimental group or a control group. The experimental group received gaze stabilization training, while the control group performed static gaze–based trunk control training. Both interventions were conducted for 30 minutes per session, three times per week for six weeks. Dynamic visual acuity and balancerelated functional outcomes were assessed before and after the intervention. Results The experimental group showed significant improvements in horizontal dynamic visual acuity, whereas no significant changes were observed in the control group. Although no significant betweengroup differences were found, large effect sizes were noted. Vertical dynamic visual acuity showed no significant within or betweengroup differences, but large effect sizes were observed. Significant improvements in balance outcomes, including the Berg Balance Scale and plantar pressure symmetry index, were found in the experimental group, with significant betweengroup differences and large effect sizes. Conclusion Gaze stabilization training was effective in improving dynamic visual acuity and balance in patients with stroke.
