The most prevalent etiology for secondary BPPV was head trauma. Secondary BPPV was associated with a higher prevalence of comorbidities including diabetes and inner ear diseases.

The experimental group included 21 participants who received a combination of VR and optokinetic stimulation in addition to VRT, while the control group, also made up of 21 individuals, only received optokinetic stimulation in conjunction with VRT. We administered the intervention sessions twice weekly over a span of 6 weeks, resulting in a total of 10-intervention sessions. Additionally, baseline, post-intervention, and follow-up assessments were conducted.ResultsOur analysis revealed that participants in both groups significantly improved with no significant differences between the groups.
