Summary
Virtual reality (VR) and optokinetic stimulation (OPK) equally improve visual vertigo (VV) symptoms. Both rehabilitation methods, combined with home exercises, enhance patients' quality of life.
Area of Science:
- Neurology
- Ophthalmology
- Vestibular Science
Background:
- Visual vertigo (VV) involves vestibular symptom exacerbation in visually complex environments like shopping malls.
- Triggers include large-format, repetitive, or moving visual patterns.
Purpose of the Study:
- To investigate the efficacy of virtual reality (VR) and optokinetic stimulation (OPK) in rehabilitating visual vertigo.
- To compare the effects of VR-based versus OPK-based vestibular rehabilitation.
Main Methods:
- Sixty VV patients were randomized into two groups for vestibular rehabilitation.
- Group I (30 patients) received VR-based rehabilitation.
- Group II (30 patients) received OPK stimulation-based rehabilitation.
Main Results:
- Both VR and OPK rehabilitation led to significant improvements in patient performance.
- No statistically significant difference was observed between the VR and OPK groups post-rehabilitation.
Conclusions:
- Intense rehabilitation programs utilizing either VR or OPK stimulation, alongside home exercises, are equally effective for managing VV.
- These approaches significantly improve the quality of life for individuals with visual vertigo.
