Name: Chaddock reflex
Synonym:
Definition: A diagnostic reflex elicited by stimulation of the skin over the surface of the lateral malleolus of the foot. The Chaddock refelx is present if there is extension of one or more or all of the toes with or without fanning of them when the external inframalleolar skin is stimulated. The Chaddock sign, similar to the Babinski sign, is taken to be an indication of disease of the spinocortical (pyramidal) tract.
