Helene Langevin is a professor in the University of Vermont College of Medicine's Department of Neurological Sciences. She is best known for discovering cellular and molecular mechanisms involved in the field of acupuncture. She is also a Professor in Residence of Medicine at Harvard Medical School, Brigham and Women's Hospital. Since 2013, Dr. Langevin is the Director of the Osher Center for Integrative Medicine, jointly owned by Brigham and Women's Hospital and Harvard Medical School.

Biography

Dr. Langevin received an MD degree from McGill University in 1978. She did a post doctoral research fellowship in Neurochemistry at the MRC Neurochemical Pharmacology Unit in Cambridge, England, residency in Internal Medicine and fellowship in Endocrinology and Metabolism at Johns Hopkins Hospital. She is a Professor in Residence of Medicine at Harvard Medical School, Brigham and Women's Hospital. She is also a part-time Professor of Neurology, Orthopedics and Rehabilitation at the University of Vermont College of Medicine. She is the Principal Investigator of two NIH-funded studies investigating the role of connective tissue in low back pain and the mechanisms of manual and movement based therapies. Her previous studies in humans and animal models have found that "needle grasp", the biomechanical component of de qi, may be caused by connective tissue winding around the needle.

Dr. Helene Langevin was appointed as Director of the Osher Center for Integrative Medicine at Harvard Medical School and Brigham and Women's Hospital in November 2012.

Effects of needle rotation

Subsequent research by Langevin has focused on the effects of rotating acupuncture needles tissue cells. In particular, Langevin discovered that:

  • Manipulation of the acupuncture needle transmits a mechanical signal to connective tissue cells via mechanotransduction.
  • By making use of ultrasound elastography, the patterns of tissue displacement by acupuncture can be mapped spatially and temporally.
  • Increased rotation of the acupuncture needle, which acts as an effective mechanical stimulus, results in increased tissue displacement
  • Acupuncture meridians

    In 2002, Langevin published a study which found that the location of acupuncture meridians corresponded to that of connective tissue planes 80% of the time.

    Reception

    A review article by the European Journal of Physiology has acknowledged that Langevin "has made a step in the right direction and her result is important to obtain the mechanical coupling between the (acupuncture) needle and the tissues".
