What is negative Babinski reflex?

The Babinski reflex occurs when the big toe extends up toward the top of the foot. Simultaneously, the other toes fan out away from each other. If this occurs in response to the test, it means that the Babinski reflex is present. If nothing occurs and there is no response, this is a neutral result.

What is the Babinski sign and what is it indicative of?

A Babinski sign in an older child or adult is abnormal. It is a sign of a problem in the central nervous system (CNS), most likely in a part of the CNS called the pyramidal tract. Asymmetry of the Babinski sign — when it is present on one side but not the other — is abnormal.

What is the Babinski reflex in adults?

Babinski’s sign is a neuro-pathological cue embedded within the Plantar Reflex of the foot. Elicited by a blunt stimulus to the sole of the foot, the normal adult Plantar Reflex presents as a downward flexion of the toes toward the source of the stimulus.
