TRIAL DESCRIPTION
Public title Virtual reality exposure therapy and fibromyalgia
Official scientific title Virtual reality exposure therapy therapy as treatment for pain catastrophizing in fibromylagia patients: Proof-of-concept
Brief summary describing the background
and objectives of the trial
Although advocated as effective for fibromyalgia (FM), the implementation of exercise in reality is hampered by patients┬┐ poor compliance. The inference that pain catastrophizing (PC) is a key predictor of poor compliance in FM, justifies altering PC during FM management. Virtual reality exposure therapy (VRET) has been used for other phobias, but not in the treatment of PC or chronic pain. This project aims to provide proof-of-concept for the development/trialing of VRET for PC in FMS.
