Experimental research of acupuncture’s effect on local pain iq: Effect of acupuncture in recovery from reduced muscle contraction of tetanized muscle and its correlation with conditions of acupuncture needling

Abstract

Denervation of guinea pig gastrocunemius muscle two weeks prior to testing suppressed acupuncture facilitation of recovery from tetanic stimulation. This result agreed with our previous conclusion that acupuncture facilitation of tetanized muscle recovery is due to an axon reflex effect. Using the above observations as criteria, the effects of various acupuncture procedures were examined. Acupuncture was effective if the needle was inserted 10 mm, but at 3 mm depth. The use of one or three needles made no difference in the acupuncture effect. Recovery was facilitated by post-tetanic insertion of the acupuncture needle; Whereas, pre-tetanic insertion produced no such effect. © 1981, The Showa University Society. All rights reserved.
