The role of chiropractic manipulation in promoting an individual's perception of psychological well being

While active manipulation was seen to exert a stronger effect than sham manipulation on markers of psychological well being, the mechanism by which this effect is generated remains unknown. The changes seen are in part likely to be attributable to aspects relating to the clinical encounter; however, these changes are minimal and fail to exert any influence over time. This suggests that chiropractic care when effective is effective because it offers effective treatment and not an effective placebo via changes in psychological well being.
