ANALYSIS OF DIFFERENT HAND PLACEMENT TECHNIQUES IN REMOTE CAMERA VIDEO HEAD IMPULSE SYSTEM
1Bezmialem Vakıf Üniversitesi, Sağlık Bilimleri Fakültesi, Odyoloji Bölümü, İstanbul, Turkey2Marmara Üniversitesi Tıp Fakültesi, KBB Anabilim Dalı, İstanbul, Turkey Objective: To investigate the effects of different hand placement techniques on remote camera vHIT system.
Materials and methods: A total of 34 healthy adult participants were included in the study. Hands around the chin and hands on top of the head techniques were used to obtain horizontal vHIT responses. Gain, accuracy, and asymmetry parameters were calculated and compared between the two techniques.
Results: There were no statistically significant differences between the two hand placement techniques for the horizontal semicircular canals in terms of gain, accuracy and asymmetry parameters.
Conclusion: Hand placement techniques do not significantly affect vHIT responses in remote camera systems. Unlike goggle-based systems, where hand placement techniques showed variable effects on gain and velocity values, remote camera system technology appears to mitigate the effects of hand placement. Nevertheless, further research is needed to investigate the optimal methods of evaluation for different vHIT systems and for different populations of people with vestibular disorders.
