Infantile Colic

What Is Colic?

Infantile colic is the term commonly used to describe an otherwise healthy infant who exhibits persistent, forceful crying for no apparent reason. The crying usually persists for several hours each day and is usually evident at least five days in each week. Parents' attempts to comfort the infant by holding and rocking the child, changing the diaper or by offering nourishment have little or no effect on the condition. The affected infant will have a tense, rumbling abdomen, with knees flexed, tight paraspinal musculature and will emit an excessive amount of gas. Occasionally the head and neck will be arched backwards.

Colic affects about 20 percent of all infants with symptoms most commonly occurring at one to four weeks of age and ending spontaneously at around three to four months. The cause of this condition has not been precisely determined, although many infants have been shown to respond well to chiropractic care.

Research studies into the effects of spinal adjustments for infants with colic have shown excellent results. The most significant study of this condition showed satisfactory improvement in over 90 percent of the infants who received chiropractic care.

In this study, 316 infants with colic received spinal evaluations and were adjusted as necessary. Improvement was noted within a two week period in 94 percent of the infants treated, on average, after only three treatments.

Evaluation of the Infant's Spine

An infant's spinal evaluation involves examining the entire spine, from the upper cervical region down to the pelvis. The examination includes motion palpation of the spine, to detect areas of decreased movement of the spinal articulations (subluxations), as well as identification of areas of unilateral, asymmetrical muscle spasm.

In the previously referenced study, the findings of the 73 chiropractors involved showed the following:

All but six percent of the infants responded to the chiropractic treatments. Fifty-three percent of the infants responded to adjustment of the upper cervical vertebrae only. Forty-one percent required adjustment of the upper cervical area in addition to the mid-thoracic articulations (T4-T9), while the remaining six percent received adjustments in other regions of the spine (lower cervical, thoracolumbar, lumbosacral and sacroiliac articulations) or a combination of two or more of the above-mentioned areas.

Adjusting the Infant's Spine

The chiropractic treatment of a young infant's spine differs from that which would be necessary for an adult. The infant's spine is more flexible, primarily due to ligament laxity. The immature spine also contains abundant cartilage which will eventually ossify into mature bone. This cartilage is quite strong and flexible, however the adjustive process is modified to ensure that only the lightest thrust is used to correct the subluxated segments. Not only is the force of the adjustment greatly decreased, the contact is usually only lightly applied with the finger tips and the thrust, if used at all, is very modest. The sound of the spine being adjusted, usually heard as a "crack" or "pop" in the adult spine, is frequently absent when adjusting the spine of a young infant. Babies usually tolerate spinal evaluation and adjusting quite well, with no more discomfort than that caused by a physical examination.


The rapid improvement seen after adjusting the spine of an infant with colic suggests that the spine is intimately involved with the digestive process. Research in this field, called the somatogastric reflex, has been developing over the past 15 to 20 years.
