Use of Repetitive Transcranial Magnetic Stimulation to Augment Hypnotic Analgesia

Summary

The investigators plan to use functional neuroimaging (fMRI) to understand the brain systems affected when hypnosis and hypnotic analgesia are augmented with repetitive transcranial magnetic stimulation (rTMS), a form of non-invasive brain stimulation to 100 people with fibromyalgia, a chronic pain condition. The investigators will measure the effect of rTMS-augmentation on the brain networks underlying hypnotizability, as well as the effect of rTMS-augmentation on hypnotic analgesia networks. The investigators hope to demonstrate that a combination of these psychological and neuromodulatory treatments will be more effective than hypnosis alone, thereby enhancing the depth of hypnosis, range of hypnosis and the efficacy of hypnotic analgesia and hopefully creating a new treatment modality for individuals suffering from pain syndromes such as fibromyalgia pain.

Conditions

• Fibromyalgia

Interventions

DEVICE

MagPro TMS system (MagVenture, Denmark)

The investigators will perform two applications of 40s of continuous theta-burst stimulation (cTBS) form of rTMS at 80% resting motor threshold (previously determined), with a 15 minute intersession interval. The standardized treatment location for the left DLPFC will be determined by Localite Neuronavigation and targeted at the posterior middle frontal gyrus. The baseline structural scan obtained during the scan 1 will be utilized for this localization process. rTMS will be delivered using a MagPro TMS system (MagVenture, Denmark). sham rTMS will be delivered using a MagPro TMS system (MagVenture, Denmark).sham rTMS will be delivered using a MagPro TMS system (MagVenture, Denmark).

BEHAVIORAL

Hypnosis

Hypnotizability will be measured using the Hypnotic Induction Profile before and after administration of real vs. sham rTMS. Hypnotizability will be measured using the Hypnotic Induction Profile before and after administration of real vs. sham rTMS. Hypnosis will be employed to influence Stroop performance (conflict detection) and for pain management. The hypnotic instructions for this will be pre-recorded and played during fMRI.
