Chiropractic care of infants with colic is a heavily used treatment today, but also a treatment that is much discussed because of uncertainty about the effect. The literature concerning this topic is surprisingly scarce, of poor quality and lack of convincing conclusions. With the present day data on this topic, it is impossible to say whether this kind of treatment has a significant effect. This underlines that the health visitors and other health-care workers cannot give guidance or suggestion of this form of treatment before more solid evidence-based findings have been reported.
