[Forgotten expertise about chiropractic].

Two forgotten experts on chiropractic are revived to expose the lack of scientific foundation of osteopathy, chiropractic and manual medicine. It is reemphasized that for the majority of patients with back complaints a precise and tangible pathologic finding explaining the pain can not be established. Likewise the correlation between radiologic, tomographic and patho-anatomic alterations with the patients complaints leaves much to be desired, particularly for the spinal column. Back ailments plagued humanity already in ancient times, their crippling effects seem, however, to be of iatrogenic origin originating in the 20th century. To explain the success stories of manual healers it is important to distinguish between medical science and the actions of the healer.
