FWIW, the NIH seems to be more open that it used to be. I found this listing of new members of the advisory board of the NIH's National Center for Complimentary and Alternative Medicine. This fellow sounds esp. interesting:
Dr. Goldstein is Medical Director of the United Cerebral Palsy Research and Educational Foundation in Washington, D.C., and is a leader among doctors of osteopathic medicine. He wrote A Challenge to the Profession: Initiate Evidence-Based Osteopathic Medicine Now and was selected to serve on a committee developing a National Center of Excellence for Osteopathic Manipulation Research. He served on the Commission on Alternative Health Care, U.S. Olympic Committee on Sports Medicine, and produced The Scientific Status of the Fundamentals of Chiropractic: A Report to Congress, and The Research Status of Spinal Manipulative Therapy. He is a former director of the National Institute of Neurological Disorders and Stroke, NIH, and a former Assistant Surgeon General, United States Public Health Service.
Don, thanks for all that you've posted about your dad and chiropracty.
