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.

Electro-acupuncture (EA) at Zusanli ST-36 can affect oesophageal motility, report Brazilian investigators. Sixteen healthy volunteers underwent an oesophageal function test using high-resolution manometry. The test was performed in three phases: basal measurements, and 20 min after acupuncture stimulation of either Zusanli ST-3, or a sham point (five centimetres medial to ST-36), in a crossover design. The results showed that both verum and sham acupuncture resulted in a subtle change in the wave velocity of the oesophageal contraction pattern. Verum acupuncture at Zusanli ST-36, but not sham, was observed to significantly decrease lower esophageal sphincter (LES) resting pressure, suggesting a potential therapeutic role for EA in the treatment of conditions involving oesophageal spasticity.
