The Effect of Chiropractic Treatment of Infantile Colic

Infantile colic is condition that affects more than 10% of babies and their families. The reason, and hence proper treatment, for this condition is unknown and many causes have been suggested. One of the treatments that parents choose is chiropractic manipulation. In Denmark, almost 10,000 babies are each year treated by chiropractors, and a high proportion is due to colic. However, the effect of chiropractic treatment of infantile colic has not been properly scientifically evaluated.

The effects of chiropractic treatment on infantile colic needs to be investigated, since this is a very common disorder with no known effective treatment, but with good empirical evidence of the value of chiropractic treatment. Although it is usually considered to be a benign and self-limiting condition, some studies suggest there might be long-term effects in terms of psychomotor problems. In worst case, the infants' crying may also lead to violence and 'shaken baby syndrome'.

Null hypothesis: There is no effect of chiropractic treatment on the course of infantile colic.

This study is a controlled, clinical trial where infants fulfilling the diagnostic criteria for colic will be randomized into two groups. One group will receive treatment and the other won't. This will determine the overall effect and furthermore, subgroup analyses will be performed to identify possible subgroups of infants, who will benefit the most from the treatment.

OBJECTIVES:

Primary: To investigate the effect of chiropractic treatment on infantile colic

Secondary: to investigate if infants with suspected musculoskeletal problems respond differently to the treatment than those without.

METHOD:

A randomized controlled single blind multicenter clinical trial

The project is to be carried out on the island of Funen, Denmark. Recruitment of babies with symptoms of infantile colic is based on contact by the parents of the babies to the project manager. Information about the existence of the study is given to health visitors, general practitioners, midwifes and to women who have given birth on the maternity ward in the University Hospital of Odense. For infants fulfilling the diagnostic criteria for colic the parents will register amount of crying using a valid instrument for at least three days before the first visit at the chiropractor Clinic (baseline registration). The babies will be randomized to chiropractic treatment or no treatment. The parents will be unaware of the child's allocation. All children have four visits during two weeks at the chiropractor. All children will be taken to the chiropractor's treatment room, while the parents stay in the reception areas. Before treatment, the chiropractors will note, whether they suspect musculoskeletal involvement or not. The parents register the amount of crying continuously during the two weeks and up to and including three days after the fourth visit. Three days after the the fourth visit, the parents are informed by the chiropractor about the child's allocation. Children in the control group will afterwards have the opportunity to have four free visits with chiropractic treatment.

The parents will be asked to give consent that the medical journal regarding pregnancy and birth is reviewed in order to obtain information on specific measures (e.g. duration of pregnancy, duration of labor, delivery presentation, vacuum extractor delivery or caesarean section). Subgroup analyses will be performed to investigate associations with symptoms of colic and suspected musculoskeletal involvement. All analyses will be adjusted for known confounders, registered by the project manager at baseline.

PERSPECTIVE FOR HEALTHCARE:

First of all, the study will evaluate the effect of chiropractic treatment of infantile colic. Secondly, it will clarify if the treatment effect differs between children with suspected musculoskeletal involvement and those without.
