Assessment of vestibulo-ocular reflex function in people with Parkinson’s disease: a cross-sectional study in a rehabilitation setting using the video head impulse test [PDF]
BMJ OpenBackground Parkinson’s disease (PD) is a neurodegenerative, progressive disorder known for motor and non-motor symptoms. The vestibular system, via the vestibulo-ocular reflex (VOR), is crucial for maintaining dynamic gaze stability, and its role in PD ...

The Video Head Impulse Test [PDF]
Frontiers in Neurology, 2017 In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal.

Video head impulse test in vestibular migraine
Brazilian Journal of Otorhinolaryngology, 2021 Introduction: Vestibular migraine as an entity was described in 1999 and its pathophysiology is still not established. Simultaneously with research to better understand vestibular migraine, there has been an improvement in vestibular function assessment.

What does the video head impulse test tell us about post-caloric vestibular recruitment? [PDF]
Brazilian Journal of Otorhinolaryngology, 2023 Objective: The vestibular recruitment observed in caloric testing is a new tool in the study of the vestibulo-ocular reflex. This study aimed to determine the sensitivity and specificity of the video head impulse test to detect post-caloric vestibular ...

The dissociation between pathological caloric testing and a normal video head impulse test helps differentiate between Menière's disease, vestibular migraine, and other vestibular disorders: a confirmatory study in a large cohort of 2,101 patients. [PDF]
Front NeurolVestibular migraine (VM) and Menière’s disease (MD) are characterized by episodes of vertigo of similar duration. It is well known that differentiation between both diseases is not always possible based only on the patient history, physical examination ...

Sensitivity of caloric test and video head impulse as screening test for chronic vestibular complaints [PDF]
Clinics, 2017 OBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction.
