The Babinski reflex is a normal reflex in babies that makes the big toe extend up and the smaller toes fan out when the sole of the foot is stimulated (usually stroked with a finger or blunt object such as a reflex hammer). The Babinski reflex is also called the Babinski sign, Babinski response, Babinski phenomenon, plantar response, plantar reflex, or the big toe sign. The Babinski Reflex is a normal response in infants up to the age of 2, in which the big toe extends upwards and backwards, while the other toes fan outwardly; however, in adults a positive Babinski Sign is pathological and often indicative of severe damage to the central nervous system.
