It is widely accepted that middle ear pathology can cause dizziness and imbalance, however this has been a challenging area to investigate, as the bi-thermal caloric test is difficult to interpret in this cohort. Recently vestibular tests that bypass the middle ear have been developed. These are the Video Head Impulse Test (vHIT) and the Bone Conduction Vestibular Evoked Myogenic Potentials (BC-VEMPs). We have successfully carried out pre-operative vHIT and BC-VEMPs on 20 patients awaiting surgery for middle ear pathologies and have shown that complete testing can be done in less than 30 minutes...

Identifying the occurrence of stroke in patients with isolated vertigo is difficult for general practitioners (GPs) as well as for physicians working in the Emergency Department. Three patients with acute vestibular syndrome are presented in this clinical lesson. The importance of an adequate neuro-otological examination is emphasised. However, many GPs lack knowledge of the nystagmus and the head impulse test. Alternative strategies for GPs are discussed.

OBJECTIVES: To evaluate the ability of saccadic strategies developed during vestibular compensation to reduce the effect of an impaired vestibulo-ocular reflex (VOR) on a retinal smear and image motion sensation. DESIGN: Twenty patients with unilateral vestibular loss were examined with a video head impulse test before and after vestibular rehabilitation (VR) with the use of gaze stabilization and refixation saccades training. Head and eye velocity functions were processed to infer the retinal eccentricity, and through its correlation with visual acuity (VA), several measurements are proposed to evaluate the influence of VR on saccades behavior and visual performance...

The Dizziness Handicap Inventory (DHI) is believed to quantitate the handicap related to the presence or severity of underlying vestibular dysfunction. However, patients with chronic vestibular diseases may manifest various degrees of behavioural and physiological adaptation resulting in variances of the DHI. Our primary study objective is to evaluate the correlation between the DHI and measurable vestibular parameters. Secondarily, we compared DHI among different vestibular disorders (central, peripheral and functional), and different types of anatomic deficits (semicircular canal vs otolithic)...

HINTS battery involving head impulse test (HIT), nystagmus, and test of skew is the critical bedside examination to differentiate acute unilateral peripheral vestibulopathy from posterior circulation stroke (PCS) in acute vestibular syndrome (AVS). The highest sensitivity component of the battery has been reported to be the horizontal HIT, whereas skew deviation is defined as the most specific but non-sensitive sign for PCS. Video-oculography-based HIT (vHIT) may have an additional power in making the differentiation...
