    Evaluation of Mental Rotation Ability in Patients with Unilateral Benign Paroxysmal Positional Vertigo
    (2023) Polat, Ani Parabakan; Demir, Serpil; Kale, Ozge; Kuntman, Berna Deniz; Erbek, Hatice Seyra; 0000-0002-8453-6069; 38088328; AAJ-2445-2021
    BACKGROUND: Our study aims to determine whether there are differences in mental rotation abilities between unilateral benign paroxysmal positional vertigo patients and healthy controls using object-based mental rotation tasks. METHODS: Our study included 17 unilateral posterior canal benign paroxysmal positional vertigo patients and 20 healthy adults. Spontaneous nystagmus test, saccade test, and dynamic positional tests with videonystagmography and object-based mental rotation test with 2-dimensional images of cubes rotated at certain angles in 3-dimensional space were performed on the participants. The mental rotation test response time and the number of correct answers were compared between patients and controls. We also evaluated whether there was a relationship between saccade test parameters and mental rotation test parameters in our study. RESULTS: No significant relationship was found between benign paroxysmal positional vertigo patients and controls on any of the dependent measures (P >.05). When we evaluated the relationship between saccadic latency and accuracy and mental rotation test response time and number of correct answers in benign paroxysmal positional vertigo patients, no significant relationship was found (P >.05). CONCLUSION: Our findings show that unilateral, posterior canal benign paroxysmal positional vertigo does not affect object-based mental rotation performance. In our study, no correlation was found between saccadic function and mental rotation ability in unilateral benign paroxysmal positional vertigo patients.

    The Middle Ear Functions and Vestibular-Evoked Potentials in Springboard-Platform Diving Children
    (2023) Borisova, Natalia; Ozer, Fulya; Kuntman, Berna Deniz; Erbek, Seyra H.; 0000-0002-8453-6069; 0000-0003-0038-8167; AAJ-2445-2021; JNE-6747-2023
    Objective: To examine the middle ear and Eustachian tube functions of children who perform springboard and platform diving sports professionally and to evaluate the vestibulospinal and vestibuloocular reflexes of these athletes with evoked myogenic potentials.Methods: Two groups consist of athletes and a control group. Pure tone audiometry and speech audiometry, Eustachian tube function test and resonance frequency in multifrequency tympanometry, and ocular/cervical vestibular-evoked myogenic potentials were performed in all participants.Results: Forty-five ears in 25 athletes were evaluated as non-patent Eustachian tube. In athlete girls, resonance frequency mean value was measured lower than the control group in both ears. Cervical vestibular-evoked myogenic potentials amplitude mean values were statistically lower in athlete girls in the left ear (P = .031), and ocular vestibular-evoked myogenic potentials amplitude mean values were statistically higher in athlete boys in the left ear (P = .024). Conclusions: Repeated diving from very high meters platform did not cause significant difference on resonance frequency of the middle ear, but cause frequently common Eustachian tube dysfunction. Acrobatic movements on the air before the diving caused changes in ocular/cervical vestibular-evoked myogenic potentials amplitude values of athletes. Eustachian tube function should be followed at different times of the year to see any effect on the performance of this sport. The importance of the vestibular system and the medial vestibulospinal tract in spring-board and platform diving athletes was emphasized first in this study. To monitor health of vestibular system and middle ear with different and more specific test materials may be important for their longer professional careers. However, this issue should be proven with future studies.
