Cervical and Ocular Vestibular Evoked Myogenic Potentials in Fibromyalgia Syndrome Patients.

Background:  Fibromyalgia syndrome (FMS) is a chronic pain condition that may be associated with dysfunction in the central nervous system.

Objective: The aim of this study was to assess the vestibulo-spinal reflex (VSR) and vestibulo-ocular reflex (VOR) in FMS using the cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) tests, respectively, and to evaluate their relation to disease severity.

Methods:  This study included 30 female FMS patients and 30 well-matched healthy controls.
