Occipital Nerve (C2) Stimulation in the Treatment of Fibromyalgia
A Randomized Controlled Pilot Study to Examine the Efficacy of Greater Occipital Nerve (C2) Stimulation in the Treatment of Fibromyalgia
The study is designed as a prospective, randomized, double-blind, single center study with a 6 month duration post permanent system implantation. Forty patients will be implanted.
During trial stimulation, patients will be randomized into one of two study arms for two weeks. Crossover will occur at the 2 week study visit to the opposite group. After completion of these two arms, every patient will subsequently complete participation in the third study arm.
After completion of the third arm, patients will be evaluated to determine if they are a positive responder responder. If so, the patient will have the option of obtaining the permanent implant.

Fibromyalgia Impact Questionnaire (FIQ)
Prazo: End of 6 week stimulation trial
|
The Fibromyalgia Impact Questionnaire (FIQ) is a self administered scale that was developed to measure fibromyalgia patient status, progress and outcomes. It measures the components of health that are most affected by fibromyalgia. The maximum score is 100 and a higher score indicates a greater impact of the syndrome on the person. The change in the Fibromyalgia Impact Questionnaire (FIQ) will be analyzed and reported. |
