Headaches can be traced back to events, emotional stress, chemical stress, physical stress, diet, dehydration and more. Extensive research has addressed the many types of headaches and the last year has seen several important publications investigating the effectiveness of chiropractic treatment and spinal manipulation. An extensive review of the literature will appear in the next issue of the Journal of Manipulative and Physiological Therapeutics (JMPT) and provides guidelines for chiropractic treatment of adult headaches. The work was done by a group of Canadians and documents the research support for chiropractic management (high-velocity, low-amplitude thrusts) for both migraine and cervicogenic headaches. Mobilization may also be effective for tension-type headache and cervicogenic headache. J Manipulative Physiol Ther. 2011 Jun;34(5):274-89.
