How to place acupuncture in a neurophysiological context. What remains to be done?
Name Klaus Lundsgaard, M.D.
Address Gl. Kongevej 80, 1850 Frederiksberg C, Denmark.
According to Medline 4.019 articles on acupuncture were published between 1982
and 19%. They cover investigations in which control groups were used in only 236
cases, equal to 6%. Only 91 articles (6 per year) conform to scientific norms.
A few meta analyses show a modest effect of acupuncture compared with placebo,
but they are not convincing. With claim rates of 97.8 or 98.6% in some articles and
a placebo effect of 0.4% in others, scientific misconduct cannot always be
discounted.
Other investigators have searched for the acupuncture points special morphology
and the physiological aspects of the meridians. They have employed radioactive
tracers and they have dissected bodies. The search has been utterly fruitless, and no
new knowledge has been added.
Time has come for a change of concepts:
Acupuncture points and meridians may be regarded as useful as the similarly
imaginary latitudes of the globe are, and they could serve well as guidelines for
nomenclature and teaching purposes. Besides, experience shows that there are points
on the human body that, treated by a needle, alone or in groups may relieve
symptoms or cure illness. This experience can be transferred to others, but at the
same time we should impress the need of further research. `Gate theory', viscero-
cutaneous reflexes and a possible influence of neurotransmitters may account for
some acupuncture action. We have yet to establish that so is the case.
In the remaining part of the speech, the author stresses heavily the need for
application of proper scientific methods. The control groups are essential (which is
exemplified), the randomisation must be correctly done, the blinding of the patient
and of the investigator is difficult but necessary, and patient groups should be large
enough for good statistical evaluation of the results. Finally, the publication should
preferably be in an international, peer-reviewed English-languished journal.
