Efficacy of Vestibular Rehabilitation Following Acute Vestibular Neuritis: A Randomized Controlled Trial.

Objective: To investigate whether a vestibular rehabilitation program started early after diagnosis of vestibular neuritis combined with standard care reduces dizziness and improves functions of daily life more effectively than standard care alone in patients with acute vestibular neuritis.

Study Design: Non-blinded, randomized controlled trial with 2 parallel groups.

Setting: Specialist centers in 2 university hospitals.

Ocular vestibular-evoked myogenic potentials (oVEMP) to skull taps in normal and dehiscent ears: mechanisms and markers of superior canal dehiscence.

The site of stimulus delivery modulates the waveforms of cervical- and ocular vestibular-evoked myogenic potentials (cVEMP and oVEMP) to skull taps in healthy controls. We examine the influence of stimulus location on the oVEMP waveforms of 18 patients (24 ears) with superior canal dehiscence (SCD) and compare these with the results of 16 healthy control subjects (32 ears). oVEMPs were recorded in response to taps delivered with a triggered tendon-hammer and a hand-held minishaker at three midline locations; the hairline (Fz), vertex (Cz) and occiput (Oz).

Ocular vestibular evoked myogenic potentials: skull taps can cause a stimulus direction dependent double-peak.

Objective: To explore the mechanisms for skull tap induced ocular vestibular evoked myogenic potentials (oVEMP).

Methods: An electro-mechanical "skull tapper" was used to test oVEMP in response to four different stimulus sites (forehead, occiput and above each ear) in healthy subjects (n=20) and in patients with unilateral loss of vestibular function (n=10).

Results: In normals, the oVEMP in response to forehead taps and the contra-lateral oVEMP to taps above the ears were similar.
