Acupuncture vs Acupressure of Brain Activation via fMRI

fMRI study of effect on brain activity according to stimulation method at LI11, ST36: painful pressure and acupuncture stimulation of same acupoints.

J Altern Complement Med. 2010 Apr;16(4):489-95. doi: 10.1089/acm.2009.0395.

Abstract

OBJECTIVES:

The objective of this study was to assess differences in brain responses between pressure and acupuncture stimulation at the same acupoint using functional magnetic resonance imaging (fMRI).

CONCLUSIONS:

In conclusion, brain signal activation patterns according to the stimulation methods and acupoints were observed to differ. Acupuncture stimulation activated more regions than pressure at the same acupoint. In particular, acupuncture stimulation activated the limbic system, such as the parahippocampal gyrus and ACC.
