Similar to the flexion withdrawal reflex, this reflex is a protective reflex of the trunk, and is intended to protect the abdominal organs from impact. In the adult, it is evoked by painful stimulation of the abdomen. However, in the infant, although more reliably elicited by noxious stimulation, it can also be elicited by innocuous stimuli such as calibrated monofilaments (von Frey hairs), its threshold in this age group being much lower than in the older child and adult. Nevertheless, above approximately one year of age, it is increasingly difficult to elicit the abdominal skin reflex using this type of stimulation.
