Investigation of the Effect of Acupuncture Needling on Connective Tissue Using Ultrasound Elastography

2014-08-27 03:57:39 | BioPortfolio

Summary

During acupuncture treatment, acupuncture needles are inserted and manipulated until a characteristic local tissue reaction termed "de qi" is observed. De qi can be perceived by the acupuncturist in the form of "needle grasp", a mechanical gripping of the needle by the tissue. De qi is considered essential to the therapeutic effect of acupuncture. Therefore, the investigator proposes that understanding this local tissue reaction will lead to an understanding of how the therapeutic effect of acupuncture therapy arises. Specifically, it is hypothesized that needle manipulation causes winding of collagen and elastic fibers around the needle. This action induces tension in the collagen network surrounding the needling site and results in a mechanical signal that is transduced into local cells. The objective of the current work is to use ultrasound elastography, a recently developed ultrasound imaging technique, to visualize and quantify changes in the elastic properties of skin and subcutaneous tissue in 12 healthy human volunteers as a result of acupuncture needle manipulation.

Medical and Biotech [MESH] Definitions

A type of massage in which finger pressure on specific body sites is used to promote healing, relieve fatigue, etc. Although the anatomical locations are the same as the ACUPUNCTURE POINTS used in ACUPUNCTURE THERAPY (hence acu-), no needle or other acupuncture technique is employed in acupressure. (From Random House Unabridged Dictionary, 2d ed). Shiatsu is a modern outgrowth that focuses more on prevention than healing.

Analgesia produced by the insertion of ACUPUNCTURE needles at certain ACUPUNCTURE POINTS on the body. This activates small myelinated nerve fibers in the muscle which transmit impulses to the spinal cord and then activate three centers - the spinal cord, midbrain and pituitary/hypothalamus - to produce analgesia.

Designated locations along nerves or organ meridians for inserting acupuncture needles.

Acupuncture therapy by inserting needles in the ear. It is used to control pain and for treating various ailments.

The occupational discipline of the traditional Chinese methods of ACUPUNCTURE THERAPY for treating disease by inserting needles along specific pathways or meridians.
