Abstract :
The study aims to establish normative data for VOR gain and also to assess the test–retest reliability of the SYNAPSYS vHIT Ulmer II System (version 3.0.0.113) in young healthy adult participants. The VOR gain was measured for all canals across a range of head velocities for 200 participants divided into two groups in the age range of 17 to 25 years with a mean age of 20.38 years. Group I (GI) – 17 to 20. 11 years, Group II (GII) – 21 – 25.11 years with a male to female ratio of 1:3. Descriptive analysis, one way AVOVA was employed to find out the significance between the VOR gain value of right lateral, right posterior, right anterior SCC’s and of left lateral, left posterior, left anterior SCC’s, Independent T test was used to assess the difference in the mean VOR gain value and Paired t test was computed to calculate the test retest reliability. The mean and standard deviation of VOR gains were 0.99 ± 0.06, 0.98 ± 0.06, 0.97 ± 0.08, 0.97 ± 0.08, 0.97 ± 0.05, and 0.97 ± 0.06 for right lateral, left lateral, right anterior, left anterior, right posterior and left posterior canals respectively. Gain differences between groups and genders were not statistically significant. The Video Head Impulse Test (vHIT) has some advantages compared to the gold standard test of horizontal SCC function including lower cost, minimal space requirements, greater portability and increased patient comfort.
