Vestibular Caloric Stimulation and the Modulation of Pain in Fibromyalgia
Vestibular Caloric Stimulation and the Modulation of Pain in Fibromyalgia: An Open Label Pilot Study
The management of chronic pains is challenging and fraught with limitations. Fibromyalgia is a common pain disorder characterized by chronic widespread pains, associated with fatigue and impaired quality of life. Fibromyalgia affects millions of people and is among the most common reasons for consulting with a rheumatologist. The food and drug administration (FDA) approved three medications to treat fibromyalgia, though there are many patients for whom these medications are ineffective, poorly tolerated or cost-prohibitive. Accordingly, there exists a need for novel therapeutics.
The researchers would like to test the therapeutic efficacy of a non-pharmacologic non-interventional bedside technique called vestibular caloric stimulation (VCS). VCS, irrigating the external ear canal with water, is a simple, non-invasive, cost-free procedure with preliminary data suggesting potential for improving pain. VCS is a form of neuromodulation and there are anatomically defined pathways elucidated to help explain how this works. There currently exists limited data on the topic, only case reports and case series. Given a clear need for additional therapeutics in many patients with fibromyalgia, the researchers have elected to conduct this trial.
