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.
