Brain Mechanisms of Psychosocial Aspects of Acupuncture Therapy

"For the MRI sessions, acupuncture needles will be inserted next to the cuff placed on the left leg and will be connected to electrodes. Low-amplitude electrical current will be activated when a button is pressed via a handheld device, controlled by the acupuncturist, in order to reduce pain, acting as an analgesic.~Additionally, electroacupuncture-induced analgesia will be used for the treatments. During the treatment sessions the acupuncturist will insert needles in several locations aimed to reduce the patient's fibromyalgia pain. Low-amplitude electrical current will be activated by the acupuncturist using the same electroacupuncture device as in the MRI machine."

The Hokanson Rapid Cuff Inflator will be placed on the lower right leg of the subject and utilized for pain testing purposes according to the protocol. Ascending pressures will be administered using the cuff to elicit different pain intensities.
