Do Inner Ear and Mastoid Bone Structural Variations Have a Determining Role on Vestibular Symptoms of Migraine?

open access: yesHaseki Tıp Bülteni, 2021
Aim:To investigate the possible relationship between morphological changes caused by anatomical structural differences and functional impairment in Vestibular migraine (VM) and Chronic Migraine (CM) disease.Methods:A total of 44 patients (VM group; 23 ...

Postural responses of galvanic vestibular stimulation: comparison between groups of older adults and young people

open access: yesRevista Brasileira de Geriatria e Gerontologia, 2020
Objective: To evaluate the effect of vestibular manipulation on the postural sway and muscle activation of younger and older adults. Methods: The study analyzed the effects of three intensity levels of galvanic vestibular stimulation (GVS) (0.3; 0.6 and

The Correlation of a 2D Volume-Referencing Endolymphatic-Hydrops Grading System With Extra-Tympanic Electrocochleography in Patients With Definite Ménière's Disease

open access: yesFrontiers in Neurology, 2021
Background: Although magnetic resonance imaging (MRI) of the membranous labyrinth and electrocochleography (ECochG) have been used to diagnose endolymphatic hydrops (ELH) in patients with Ménière's disease (MD), the relationship between imaging and ...

Triangular labyrinth fractals [PDF]

open access: yesFractals, Vol. 27, No. 8 (2019) 1959131 (31 pages), 2020
We define and study a class of fractal dendrites called triangular labyrinth fractals. For the construction, we use triangular labyrinth patterns systems that consist of two triangular patterns: a white and a yellow one. Correspondingly, we have two fractals: a white and a yellow one.

A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]

open access: yes, 2003
Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

Consumer Demand for Online Dizziness Information: If You Build It, They May Come

open access: yesFrontiers in Neurology, 2014
Objective: Dizziness is a common reason patients present to doctors, but effective diagnostic tests and treatments for dizziness are underused. The internet is a way to disseminate medical information and is emerging as an intervention platform.

Mixed labyrinth fractals [PDF]

open access: yesTopology and its Applications, Vol.22 (2017), 112-125, 2020
Labyrinth fractals are self-similar fractals that were introduced and studied in recent work by Cristea and Steinsky. In the present paper we define and study more general objects, called mixed labyrinth fractals, that are in general not self-similar and are constructed by using sequences of labyrinth patterns. We show that mixed labyrinth fractals are

Padrão radiológico da otosclerose coclear. Estudo por TC de 14 doentes.

open access: yesActa Médica Portuguesa, 1994
In this review of cochlear otosclerosis 14 cases were studied by CT scan aiming to establish a densitometric pattern of the capsular foci and relating it to the hearing and vestibule dysfunctions.

On the length of arcs in labyrinth fractals [PDF]

open access: yesCristea, L.L. & Leobacher, G. Monatsh Math (2018) 185: 575, 2018
Labyrinth fractals are self-similar dendrites in the unit square that are defined with the help of a labyrinth set or a labyrinth pattern. In the case when the fractal is generated by a horizontally and vertically blocked pattern, the arc between any two points in the fractal has infinite length [Cristea\&Steinsky 2009,Cristea\&Steinsky 2011].
