Vestibular Pain Interactions (VPI)

July 11, 2015 updated by: Lucian Macrea, University of Zurich

Modulation of Pain Responses by Vestibular Stimulation. A Contact Heat Evoked Potential Study.

The goal is to establish the practical usefulness of vestibular stimulation for modulating pain perception and to describe the possible mechanisms that could underlie neural vestibular-somatosensory interactions.
