To identify the influence of twisting or untwisting Taixi (K13) on the brain function by observing functional magnetic resonance imaging.METHODS:
Twelve healthy young cases were enrolled in this research. A block design including three blocks which baseline and stimulation appear alternately was adapted. In stimulation phase, the needle was twisted manually, or not twisted. Scanned images were analyzed using SPM2.RESULTS:
The right superior temporal gyrus (BA22), left medial frontal gyrus (BA46), followed by right and left postcentral gyrus of parietal lobe (BA2, BA3), left inferior frontal gyrus (BA45) and left inferior parietal lobule (BA40) were evoked by acupuncture at Taixi, but there was no activeation area after untwisting acupoint.CONCLUSION:
The different areas evoked by twisting or untwisting Taixi acupoint are closely related with the internal organs as well as the course of the channels and collaterals.
