69. Abdominal acupuncture reduces pain at the spinal cord level

Abdominal acupuncture (AA) reduces laser-evoked potentials (LEP) amplitude and laser pain perception in healthy subjects (Pazzaglia et al., 2014). The aim of the current study was to investigate the site of AA analgesic effect.We recorded LEPs in 10 healthy volunteers by using the 32 EEG scalp electrodes. The experimental protocol included 3 times: (1) baseline, in which LEPs to stimulation of the bilateral dorsal wrist and right foot were recorded before acupuncture; (2) acupuncture, in which LEPs were recorded during AA performed in the abdominal area corresponding to right wrist; and (3) rest, in which LEPs were recorded 15min after the needle removal.
