In this study published in the Journal of Manipulative and Physiological Therapeutics (23(4): 225-230. May 2000.), researchers tried to determine if spinal manipulation and ischemic compression could effectively help fibromyalgia patients. The goal was to reduce the sleep disturbance, the intensity of pain, and the fatigue associated with fibromyalgia. After 30 treatments, more than 3/4 of the study participants had reduced pain intensity. Sleep quality improved in almost 2/3 of the participants. 3/4 of the participants experienced less fatigue. These improvements were sustained even one month later. The findings suggest that chiropractic can benefit fibromyalgia patients.
