Objective: The study aimed to explore the vestibular function in children with neurodevelopmental disorders (NDDs).

Methods: Twenty-eight participants with a NDD (6 girls, 22 boys; 6-13 years; 9;3 ± 2;4 years) were enrolled in this pilot study. Sixteen participants had a single NDD (Autism Spectrum Disorder: n = 7, Developmental Coordination Disorder: n = 3; Attention Deficit/Hyperactivity Disorder: n = 6), the remaining 12 had comorbid NDDs. The integrity of the peripheral vestibular system was evaluated using ocular and cervical Vestibular Evoked Myogenic Potentials (o/cVEMP), and a video Head Impulse Test (vHIT); motor competence was assessed with the Movement Assessment Battery for Children, and the KörperkoordinationsTest für Kinder. Results were compared to an age and sex-matched control group (n = 28; 9;7 ± 1;9 years).

Results: The NDD group exhibited significantly higher interpeak amplitudes on both VEMP tests compared to the control group (p < 0.001). No significant differences were found between the groups on vHIT measurements (p > 0.05). Among the children with NDDs, 11 (39 %) showed atypical vestibular responses, including one child with vHIT correction saccades and three children with reduced or absent otolith responses (n = 3). Additionally, eight children showed abnormally elevated otolith amplitudes (cVEMP > 4.00 µV; oVEMP > 55.00 µV).

Conclusions: Clinicians are encouraged to recognize the overlap and consider the possibility of vestibular alterations in individuals with NDD.

Significance: Incorporating vestibular assessments into routine clinical evaluations, particularly in children with NDD who exhibit delayed motor development, balance issues, hearing loss, or vestibular-related symptoms, is strongly recommended.

Background: The perception of Subjective Visual Vertical (SVV) is crucial for postural orientation and significantly reflects an individual's postural control ability, relying on vestibular, visual, and somatic sensory inputs to assess the Earth's gravity line. The neural mechanisms and aging effects on SVV perception, however, remain unclear.

Objective: This study seeks to examine aging-related changes in SVV perception and uncover its neurological underpinnings through functional near-infrared spectroscopy (fNIRS).

To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness. The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group.

Background: Gait instability and falls significantly impact life quality and morbi-mortality in elderly populations. Early diagnosis of gait disorders is one of the most effective approaches to minimize severe injuries.

Objective: To find a gait instability pattern in older adults through an image representation of data collected by a single sensor.
