Experiment 2. As good performance of VG on vHIT compared to Oto and ESC systems.
To test the efficiency of the new goggle that could record from either eye and further evaluate performances of the new vHIT system, VertiGoggles ZT-VNG-I (VG), we conducted a two-center clinical project in comparison to the longstanding systems, OtometricsICS impulse (Oto) and EyeSeeCam (ESC). Given that the experiments were carried out separately, we applied the t-test to analyzed our data (Figure 3 and Table S1). First of all, there was no significant difference found in between the systems on the lateral semicircular canals, which indicated the stability and reliability of this plane across systems. However, differences showed up on the vertical canals. For the RALP plane, the VOR gain were similar between VG and Oto. But VG showed significant difference in comparison to ESC that the gain was closer to 1 with smaller variations. Furthermore, for the LARP plane, three systems performed similarly on the LA. But the results of VG were different from either Oto or ESC on the RP canal. The VOR gain we obtained from VG was closer to 1 with less standard deviations in either comparison. Our data indicated three systems has comparable performance in vHIT. Besides, with the convenience provided by the new goggle, the VOR gain from RP canal is recorded even better.
