A study published in the Journal of Manipulative and Physiologic Therapeutics (Nov/Dec 1999:22(9), pp582-85) shows that chiropractic may be beneficial to women suffering with PMS. It was a small study; 25 women were given either chiropractic adjustments or “sham” adjustments and evaluated over 9 months using a standard PMS questionnaire. The women receiving the chiropractic care reported a decrease in symptoms.
