More than one Belgian out of 3 consulted at least once in his life an osteopath, a chiropractor, a homeopath or an acupunctor. Within the framework of the continuation of the setting pursuant to the law Stuck, the Minister for the public health asked the federal Center of expert testimony health care (KCE) carry out an inventory of fixtures of these 4 not-conventional medicines with success. In a first report (December 2010) KCE was concentrated on the study of osteopathy and chiropractic. This time, it is with the turn of acupuncture. This therapy was studied from a point of view scientific, sociological, legal and organisational, a first in Belgium!
