Over 20 years ago ( Journal of Manipulative and Physiological Therapeutics 2/2000) a scientific research article was published in the peer reviewed literature describing how chiropractic care could help migraine headaches. A randomized controlled trial of six months duration using 133 subjects (83 manipulation and 40 controls) with a minimum of one migraine/month was done. The majority of subjects had migraines for 18 years.
The intervention was 2 months of chiropractic care for the 83 patients and interferential therapy for the 40 controls. The study revealed the following:
1. 22% of participants reported more than a 90% reduction of migraines as a consequence of 2 months of chiropractic adjustments.
2. 50% reported a significant improvement in the morbidity of each episode.
3. 59% reported no neck pain as a consequence of the 2 months of chiropractic care.
4. The greatest improvement was in medication use. A significant number of participants recorded that their medication use had reduced to zero by the end of the 6-months trial.
There have now been several studies demonstrating significant improvement in headaches or migraines after chiropractic adjustments.
