Systematic Review of Normative Data for the vHIT Using the EyeSeeCam System in Adults With Normal Vestibular Function

This is the first review focusing exclusively on EyeSeeCam-based normative values. Despite methodological differences, horizontal canal gains consistently cluster around 0.80. Our synthesis and expert consensus propose 0.70 as a clinically acceptable lower cutoff for VOR gain across all semicircular canals. This threshold strikes a balance between sensitivity and specificity. Our findings highlight the need for standardized vHIT protocols and support the development of system-specific normative criteria.
