Objectives: Lateral semicircular canal BPPV (LSC-BPPV) is diagnosed with the Head Yaw Test (HYT) by observing nystagmus direction and comparing the nystagmus intensity on both sides according to Ewald's laws. Head Pitching Test (HPT) is a diagnostic maneuver performed in the upright position by bending the patient's head forward (bowing) and backward (leaning) and observing the evoked nystagmus. We aimed to assess the sensitivity of HPT in correctly diagnosing LSC-BPPV through the quantitative measurement of Bowing and Leaning nystagmus slow-phase velocity (SPV).

- The study aimed to connect the length of spontaneous and hyperventilation-induced nystagmus (HVIN) with the causes of acute unilateral vestibulopathy in patients.
- It analyzed data from 198 patients, revealing that those with short-lasting nystagmus were typically older and had higher cardiovascular risk, with most showing paretic HVIN.
- In contrast, patients with long-lasting nystagmus were generally younger and had lower vascular risks, with a mix of HVIN patterns present, suggesting both vascular and inflammatory causes may be involved.
Objective: Study the high-frequency vestibulo-oculomotor reflex in posterior canal benign paroxysmal positional vertigo (BPPV) through Video Head Impulse Test (vHIT).
Methods: 150 patients suffering for the first time from posterior canal BPPV were studied. Posterior canal vestibulo ocular reflex (VOR) gain was analysed through stimulations in right anterior-left posterior and left anterior-right posterior planes before treatment, immediately after resolution of the acute stage and one month later.
