Eleven women with histories of PMS symptoms that had occurred regularly for more than 4 months were given chiropractic spinal adjustments. The care continued for four menstrual cycles and consisted of 5-7 spinal adjustments per month. The subjects were given questionnaires at the beginning and end of the care. They evaluated changes in irritability and mood swings, tension, ineffectiveness, lack of motor coordination, mental/cognitive functioning, eating habits, variations in sexual drive and activity, overall physical symptoms, and social impairment. The subjects reported improvement in all ten categories with the greatest improvement of symptoms relating to variations in sexual drive (70.7%), social impairment (64.5%), and mood swings (60.8%). The average improvement in all symptom categories was 44.2%.
