Postural disturbances in advanced Parkinson's disease are less responsive to therapy than other cardinal motor signs. The vestibulocollic reflex represents one brain-stem neuronal circuit involved in postural adjustments. The objective of this study was to investigate the vestibulocollic reflex in parkinsonian patients and the effects of subthalamic stimulation and dopa by recording vestibular-...

Background: The incomplete maturation of brain in preterm children results in long-term neurodevelopmental impairment. This study aimed to investigate the static balance function in children with a history of preterm birth. Methods: Participants were 31 preterm children including 21 moderately preterm (MPT), 10 very preterm (VPT), and 20 term children aged 5.5 and 6.5 years. The cervical ves...

Aim:To evaluate vestibular evoked myogenic potentials in patients with multiple sclerosis as method of diagnostic support. Study design: Case-control. Material and Method: We studied a group of normal individuals (n=15) and a Studied group (n=15) that comprised patients with diagnosis of multiple sclerosis. Both groups were submitted to vestibular evoked myogenic potential exam. In each ear it ...

Recently, a new indicator of vestibular otolithic function has been reported: it is a series of negative-positive myogenic potentials recorded by surface electrodes on the skin beneath the eyes in response to bone-conducted vibration (BCV) delivered to the forehead at the hairline in the midline (Fz). The potential is called the ocular vestibular-evoked myogenic potential (oVEMP) and the first ...

OBJECTIVES/HYPOTHESIS To determine if vestibular potentials could be elicited with electrical stimulation from cochlear implants. STUDY DESIGN Prospective cohort study. METHODS Vestibular responsiveness to electrical stimulation from cochlear implants was assessed via vestibular evoked myogenic potential (VEMP) testing in 53 pediatric and young adult patients. RESULTS Thirty-one participa...

MATERIALS and METHODS: Caloric tests, cervical vestibular evoked myogenic potentials (cVEMPs), and SVV deviations were studied in a group, including 20 patients with migraine without aura (MoA), 24 patients with vestibular migraine (VM), 20 patients with tension-type headache (TTH), and 30 healthy controls. SVV deviations were measured using a translucent bucket. The procedure was repeated 10 t...
