  1. Unorthodox?

    26 September 2014

    John Hart, Self


    I have three questions regarding the paper by McGregor et al, [1] if I may.  

    1. On page 3 of the article it is stated that the “most extreme unorthodox view” in chiropractic was the one that treated a “lesion” (e.g., chiropractic subluxation) to remove an “obstruction to human health.” Dr. James Winterstein, then-president of the National University of Health Sciences, has indicated that the target of chiropractic intervention is a “functional articular lesion,” [emphasis added], and that the purpose of said intervention is to “produce [a] beneficial neurological effect.” [2] Do the authors consider this latter similar viewpoint, also to be “extremely unorthodox”? 

    2. For a definition of “orthodox,” the authors defer to a group outside of chiropractic, namely “a majority of North American orthopedic surgeons.” Here, the definition is based on what chiropractic is not, e.g., chiropractic intervention is “not effective for non-musculoskeletal conditions.” Is there some reason the authors did not cite the statistic by McDonald et al [3] who found that the majority of North American chiropractors (76.5%) do think there is a relationship between vertebral subluxation and visceral health?  

    3. Would the authors consider a chiropractic study on atlas re-alignment and blood pressure, led by a researcher at the University of Chicago [4] as extremely unorthodox or just mildly unorthodox?
