Evid Based Complement Alternat Med. 2005 September; 2(3): 315–319.

Summary of imaging studies, their subjects and conclusions (in date order of publication)

Author Type n Subject type Finding Condition Intervention
Alavi et al. (1) PET 5 Pain Reduction of thalamic asymmetry Pain RA
Cho et al. (2) fMRI 12 HV Point-specific effect for vision-related acupoint NP RA
Wu et al. (24) fMRI 9 HV Activation of pain matrix (primary and secondary somatosensory cortex, insula, anterior cingulate prefrontal cortex, hypothalamus and PAG) Pain RA
Cho et al. (5) fMRI ? HV Point-specific effect for auditory-related acupoint NP RA
Hui et al. (25) fMRI 13 HV Activation of pain matrix Pain RA
Hsieh et al. (27) PET 16 HV Both activate insula, anterior cingulated, cerebellum. Hypothalamus only activated by RA Pain RA versus sham
Biella et al. (29) PET 13 HV Anterior cingulate cortex activated by RA Pain RA versus sham
Lee et al. (7) fMRI 24 Rats cFos expression in visual cortex in response to stimulation of vision-related acupoint NP RA
Siedentopf et al. (8) fMRI 18 HV Point-specific effect for vision-related acupoint NP Laser
Gareus et al. (10) fMRI 21 HV No point-specific effect for vision-related acupoint NP RA
Wu et al. (22) fMRI 15 HV EA activated the pain matrix more than sham EA Pain EA versus MEA versus Sham EA versus Mock EA
Kong et al. (26) fMRI 11 HV Both activate pain matrix Pain RA versus EA
Li et al. (6) fMRI 18 HV Point-specific effect for vision-related acupoint NP RA versus EA
Li et al. (11) fMRI 17 HV Point-specific effect for ‘language’-related acupoint NP RA
Chiu et al. (20) fMRI 38 Rats EA produced a greater activation of pain matrix than other interventions Pain Sham versus Sham EA versus EA
Zhang et al. (23) fMRI 48 HV Activation of pain matrix Pain EA
Litscher et al. (9) fMRI 1 HV Increased activity of visual cortex on use of vision-related acupoint NP Laser
Yoo et al. (12) fMRI 12 HV Point-specific effect for nausea NP RA
Liu et al. (21) fMRI 7 HV Activation of PAG Pain RA
Fang et al. (28) fMRI 15 HV Point-specific effect from RA Pain RA versus sham
Pariente et al. (30) PET 14 OA Specific effect for RA. Expectation elicits non-specific physiological effect Pain RA versus SN versus OP
Yan et al. (13) fMRI 37 HV Specific effects for Liv3 and LI4

HV, healthy volunteer; OA, patient with Osteoarthritis; NP, non-pain; RA, real acupuncture; Sham, needling at a non-acupoint; EA, electroacupuncture; MEA, minimal (penetration) electroacupuncture; SN, Streitberger needle; OP, overt placebo.
