Background: Measurement of ocular counterrolling (OCR) is well known as a simple method to evaluate the peripheral vestibular organ, especially the otolith organ. But it has rarely been used because of the difficulty in differentiating between pathologically reduced OCR and the wide physiological variation of this parameter.
Patients: In this study, the OCR of 55 patients with unclarified vertigo (n = 20), vestibular neuronitis (n = 15), Menière's disease (n = 10), and benign paroxysmal positional nystagmus (n = 10) were evaluated and compared to a control group (n = 30) with the intention of diagnosing peripheral vestibular dysfunction and establishing a differential diagnosis. The test sequence was carried out with Vesta goggles by Panares and included head tilts of 5 degrees, 15 degrees, and 30 degrees to the left and right.
Results: The results show a significantly reduced OCR in patients suffering from peripheral vestibular disorders when compared to the control group.
Conclusion: There is no specific finding for a specific type of vestibular lesion, but otolith function is affected in several disorders as measured by ocular counterrolling.

Objective: What we hear may influence postural control, particularly in people with vestibular hypofunction. Would hearing a moving subway destabilize people similarly to seeing the train move? We investigated how people with unilateral vestibular hypofunction and healthy controls incorporated broadband and real-recorded sounds with visual load for balance in an immersive contextual scene.
Design: Participants stood on foam placed on a force-platform, wore the HTC Vive headset, and observed an immersive subway environment.

Background: Taylor and Palmer introduced an angiosome (vascular) concept in reconstructive plastic surgery in 1987. The angiosome is considered a segment of a nerve (cranial or peripheral nerve) supplied by a primary source of blood vessels.
Purpose: To observe the arteries supplying the vestibulocochlear nerves (VIII) from the brainstem till their termination.

Positional downbeat nystagmus (pDBN) is a common finding in dizzy patients, with etiologies ranging from benign paroxysmal positional vertigo (BPPV) to central vestibular lesions. Although peripheral pDBN often presents with distinct clinical features that differentiate it from BPPV, diagnosing its etiology can be challenging. A thorough clinical evaluation, including the physical characteristics of the nystagmus, response to positional maneuvers, and neurological findings, is often sufficient to diagnose conditions that provoke pDBN such as anterior canal BPPV, atypical posterior canal BPPV, and central causes.

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.

Type 2 Diabetes is a highly prevalent chronic disorder that affects multiple systems through microvascular complications. Complications such as diabetic peripheral neuropathy, diabetic retinopathy, and diabetic vestibular dysfunction (vestibulopathy) all directly interfere with the sensory components of balance and postural stability. The resulting impairments cause increased falls risk and instability, making it difficult to perform daily task or exercise.
