Scalp electro-acupuncture (EA) can be successfully used to reduce pain severity and disability in headache patients. Japanese investigators treated 54 primary headache patients at two bilateral points located on the occipital scalp with 50 Hz EA for 15 minutes, once a week for three months. Headache intensity significantly declined as a result of the treatment (mean reduction in pain scores from 7.4 at baseline to 4.9 at three months), alongside an improvement in quality of life. Monthly headache days significantly decreased (from 18 at one month to 14 at three months), accompanied by a reduction in monthly acute headache medication days (from 8 to 6.4). Depression scores also showed significant improvement.
