The aim of this study is to evaluate the impact of electro-acupuncture in pain processing on patients with fibromyalgia (FM). The investigators hypothesize that electro-acupuncture is effective for FM because it functions as a desensitization therapy, which when applied repeatedly over multiple treatment sessions, gradually habituates the nervous system to continuing pain and sensory signaling.

Brief Summary
The aim of this study is to evaluate the impact of electro-acupuncture in pain processing on <br /> patients with fibromyalgia (FM). The investigators hypothesize that electro-acupuncture is <br /> effective for FM because it functions as a desensitization therapy, which when applied <br /> repeatedly over multiple treatment sessions, gradually habituates the nervous system to <br /> continuing pain and sensory signaling.
Detailed Description
This study design has two components: 1) a cross sectional assessment of brain chemistry,
connectivity and response to pain in healthy controls and age- and sex-matched fibromyalgia
patients, and 2) a longitudinal assessment of the same outcomes in fibromyalgia patients
randomized to either electro-acupuncture (EA) or laser acupuncture.
The investigators will evaluate 80 fibromyalgia patients who will receive acupuncture
treatment twice a week for 4 weeks, for a total of 8 treatments. Baseline data from these
patients will be compared to results from 40 pain-free controls.
Participants will undergo experimental pain assessments as well as brain neuroimaging.
Note added after completion of study data gathering: Within the registration in
ClinicalTrials.gov and the informed consent, one arm was referred to as "non-traditional
acupuncture". In fact, this was a control arm, receiving mock laser acupuncture (Vita Laser
650, Lhasa OMS). They received 2 treatments per week for 4 weeks. As consented, they were
told, with IRB permission, that they were receiving non-traditional laser acupuncture. This
deception was essential to maintaining scientific integrity of the masking.
The laser acupuncture device (Vita Laser 650, Lhasa OMS) was positioned over all of the same
acupoints used in electro-acupuncture (EA), but was turned off during treatment sessions.
There was no palpation prior to positioning these devices, and there was no physical contact
between device and skin.
Treatments and/or Procedures
Laser acupuncture (Non traditional Acupuncture)
For non-traditional acupuncture, a laser acupuncture device (Vita Laser 650, Lhasa OMS) will be positioned over all of the same acupoints used in EA. There will be no palpation prior to positioning these devices, and there will be no physical contact between device and skin.
Needle acupuncture traditional acupuncture
This group will receive needle acupuncture at 3 pairs of sites. The needles will be stimulated with low intensity, low frequency electric current using a constant-current electro-acupuncture device (AS Super 4 digital needle stimulator).
Outcome Measures
Outcome measures are the tests that investigators perform to prove whether or not a treatment being tested in a clinical trial is having any effect.
Primary
Brain Neurocircuitry Underlying Chronic Pain (Percent of Time of a Somato-sensory Cortex Coactivation Pattern)
Characterize the altered somatosensory-related neurocircuitry underlying chronic pain in FM, as shown by the difference in brain connectivity between healthy controls and FM patients as measured by FMRI (occurrence rate of co-activation pattern). For each arm, the coactivation pattern was assessed at rest and during a pressure pain stimulation. This is measured by the percent of scan time that an individual's brain displayed a particular coactivation pattern related to the somatosensory system.
Primary
Change in Brain Connectivity With Acupuncture Treatment
Brain connectivity will be assessed at baseline and following either electro-acupuncture or mock laser acupuncture. Primary somatosensory cortex to insula connectivity. (Z-stat) A positive Z score reflects positive correlation in FMRI signal between different between brain areas. A negative Z score represents anti-correlation between in FMRI signal between brain regions. These scores reflect either positive connectivity or inhibitory connectivity. A mean of 0 represents no correlation or connectivity between regions.
Secondary
Change in Brain Neurochemistry of Combined Glutamate and Glutamine (Glx) Within the Anterior Insular Cortex With Acupuncture Treatment
Brain neurochemistry assessed at baseline and following either electro-acupuncture or mock laser acupuncture using proton magnetic resonance spectroscopy (1H-MRS) measures of combined glutamate and glutamine (Glx).
Secondary
Change in Brain Neurochemistry of Gama-aminobutyric Acid (GABA) Within the Anterior Insular Cortex With Acupuncture Treatment
Brain neurochemistry assessed at baseline and following either electro-acupuncture or mock laser acupuncture using proton magnetic resonance spectroscopy (1H-MRS) measures gama-aminobutyric acid (GABA).
Other
Predicting Response to Acupuncture Using Brain Neurochemistry
Baseline neuroimaging outcomes of neurochemistry are used to predict subsequent response to electro-acupuncture and laser acupuncture.
Other
Predicting Response to Acupuncture Using Brain Connectivity
Baseline neuroimaging outcomes of connectivity are used to predict subsequent response to electroacupuncture and laser acupuncture.
Study Criteria
Inclusion Criteria for Fibromyalgia Participants
- Have self-reported FM symptoms for at least one year and also meet the Wolfe et al
2011 criteria for Fibromyalgia.
- Continued presence of pain more than 50% of days.
- Pain greater than a certain threshold on the Visual Analog Scale (VAS) for pain; 7-day
recall; [Note: The VAS is widely used in clinical pain research and as such we chose
to use it for inclusion criteria and for clinical pain assessment below. Within our
group numerical ratings scales 0-100 are more commonly used in quantitative sensory
assessment, and as such we chose to use NRS scales for evoked pain assessments below.]
