From the Sunday Boston Globe Magazine comes this insight into some fascinating research into acupuncture.
Langevin grabbed headlines when, in 2001, the Journal of Applied Physiology published the results of a study in which she and her colleagues quantified de qis biomechanical component, or needle grasp, by measuring the force necessary to pull an acupuncture needle out of the skin. Her findings showed something else: Gently manipulating the needles back and forth or twisting them increased the grasp significantly. Since then, Langevins research has proved that the connective tissue that winds around acupuncture needles much like spaghetti wadded around a fork is responsible for needle grasp. Further study has revealed that needle manipulation transmits a signal to fibroblasts, the cells that make up such tissue, causing them to spread and flatten. "The needle is, in fact, stretching the tissue from the inside," Langevin explains. "The tissue is not just being pulled; it's actively responding to the stimulus."
I appears that Dr Langevin is onto something.
