Basic Information

• Recruitment Status: COMPLETED

Brief Summary

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.

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.

Study Groups

Controls

Healthy pain free controls will be recruited for comparison with fibromyalgia patients.

Group Type: NO_INTERVENTION

No interventions assigned to this group

Non-Traditional Acupuncture

40 fibromyalgia patients will be randomized to non-traditional laser acupuncture (Vita Laser 650, Lhasa OMS). They will receive 2 treatments per week for 4 weeks.

Group Type: ACTIVE_COMPARATOR

Laser acupuncture (Non-traditional Acupuncture)

Intervention Type: DEVICE

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.

Traditional Acupuncture

40 fibromyalgia patients will be randomized to receive electro acupuncture (AS Super 4 digital needle stimulator, Harmony Medical Co) . They will receive 2 treatments per week for 4 weeks.

Group Type: ACTIVE_COMPARATOR

Needle acupuncture (Traditional Acupuncture)

Intervention Type: DEVICE

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).
