In this study, 73 chiropractors adjusted the spines of 316 infants (median age 5.7 weeks at initial examination) with moderate to severe colic (average 5.2 hours of crying per day). The infant's mothers were provided a diary and kept track of the baby's symptoms, intensity and length of the colicky crying as well as how comfortable the infant seemed. 94% of the children within 14 days of chiropractic care (usually three visits) showed a satisfactory response. After four weeks, the improvements were maintained. One fourth of these infants showed great improvement after the very first chiropractic adjustment. The remaining infants all showed improvement within 14 days. Note: 51% of the infants had undergone prior unsuccessful treatment, usually drug therapy.
