Neuroimaging Approaches to Deconstructing Acupuncture for Chronic Pain

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).

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.
