This work aims at evaluating the role of the vestibular system in the postural sway control using the coherence function. A sample of 19 young, healthy male adults was monitored with a three axial accelerometer placed over the head during a stabilometric test, standing on a force platform during 3 min in four conditions: eyes closed and open, and feet apart and together. The magnitude squared coherence (MSC) function and Monte Carlo simulation was used to correlate changes in body sway with head accelerations. Significant MSC values were found in the frequency range 0.1-0.5 Hz, mainly in conditions of larger oscillations: eyes closed and feet together. These results may be related to utricular otoliths responses and ankle strategy.

The integration of different sensory streams is required to dynamically estimate how our head and body are oriented and moving relative to gravity. This process is essential to continuously maintain stable postural control, autonomic regulation, and self-motion perception. The nodulus/uvula (NU) in the posterior cerebellar vermis is known to integrate canal and otolith vestibular input to signal angular and linear head motion in relation to gravity.

Vestibular rehabilitation, an evidence-based physical therapy approach, plays a crucial role in managing and recovering from gaze and balance disorders, including those of central origin. This study, targeted at the community of Italian healthcare practitioners, is vital in understanding the application of vestibular rehabilitation in neurological disorders and in identifying knowledge gaps, barriers, and future directions. This is a cross-sectional study directed at healthcare professionals involved in neurorehabilitation in Italy.

The inner ear houses both hearing and balance sensory modalities. The hearing and balance organs consist of similar cell types, including sensory hair cells and associated supporting cells. Previously we showed that is required for maintaining supporting cell survival during cochlear maturation.

High-flow nasal oxygen therapy (HFNO) is highly versatile and employed in varied situations, including after extubation, in cases of respiratory failure, and at the end of life. However, its impact on swallowing function is not yet elucidated. Therefore, this scoping review aimed to clarify how HFNO affects swallowing function and whether it poses a risk for aspiration pneumonia.

Objective: To better understand the clinical phenotype of Ménière's disease (MD), we examined family history, thyroid disorder, migraine, and associated disorders in complaints of people living with MD.
Method: We designed the study as a retrospective and examined data gathered from 912 participants with MD. Their data were originally collected by the Finnish Ménière Federation (FMF).
