The 2005 conference on the biology of manual therapies.

A historic and critically important scientific workshop for all professions involved with manual therapies was held at the National Institutes of Health (NIH) on June 9 and 10, 2005. The conference was jointly sponsored and organized by the NIH and the Canadian Institutes of Health Research and was the first ever national or international research conference to focus on the biologic mechanisms that underlie a broad range of interventions, which can be described as "manual therapies." Leading scientific experts from North America and Europe presented their latest findings and theories related to 5 different areas of science relevant to manual therapies: neuroscience, biomechanics, endocrinology, imaging, and immunology. During the conference, breakout groups composed of scientists, physicians and therapists, and patient advocates were formed in the relevant disciplines. These groups developed consensus statements on key unanswered research questions, which were then submitted back to the conference for comment and approval. The outcomes of this workshop have subsequently been incorporated into a new initiative by the NIH and Canadian Institutes of Health Research for funding research on the biology of manual therapies. This editorial includes presentation summaries and 13 key consensus recommendations relating to mechanisms of action for manual therapies.
