Abstract
I
The following two CME questions need to be amended to include the text indicated in bold:
2. The author's evidence for the fundamental correspondence of the Principal channels with the peripheral nervous system includes:
a. in-depth analysis of human embryologic development.
b. analysis of human anatomy.
c. cross-sectional anatomy of acupuncture needle passages at classical acupoints.
d. These relationships have been demonstrated for every classical acupuncture point.
e. Analysis of a collection of acupoints demonstrates that they approximate specific nerves.
3. In the model presented by the author:
a. the ideal target structure for needling in the extremities should be peripheral nerves rather than muscles and fascia.
b. the “de qi” sensation is postulated to represent activation of nerve fiber endings when contacted by the needle.
c. twirling of the needle in the fascia is postulated to mechanically activate the small myelinated and unmyelinated fibers that penetrate fascia at the acupuncture points.
d. the slow spread of “qi sensation” along a channel reflects the slow transmission of unmyelinated autonomic fibers.
e. the ancient concept of Qi flowing in discrete channels separate from commonly recognized anatomic structures is an essential aspect of this model.
The online version of the article has been corrected to reflect this change.
The authors of the CME questions wish to apologize for the omission of this text.
