  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Chiropractic and the risk of chest injury

    Dynamic chest compression occurs during spinal manipulation.

    Researchers at the Medical College of Wisconsin, in Milwaukee, analyzed the magnitude of chest compressions during chiropractic manipulation.

    First, the details.

    • Part 1: A crash dummy was used to measure chest compression during “normal” chiropractic manipulation and spinal manipulations with maximum effort at the midback (T7 to T8 vertebrae).
    • Part 2: A mechanical device was used to apply and measure the forces necessary to induce chest compression in the test dummy.
      • These forces were increased until injurious levels of force were reached.
    • The likelihood of injury was assessed and classified using the Abbreviated Injury Scale (AIS) — a classification system correlated to injury thresholds.

    And, the results.

    • Manipulations using typical and maximum efforts resulted in maximum chest compressions corresponding to minimal risk of minor (AIS 1 level) injuries.

    The bottom line?

    Interesting and reassuring.

    A PubMed search revealed no similar studies.
