<P> The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument . The reflex can take one of two forms . In normal adults , the plantar reflex causes a downward response of the hallux ( flexion ) . An upward response ( extension ) of the hallux is known as the Babinski response or Babinski sign , named after the neurologist Joseph Babinski . The presence of the Babinski sign can identify disease of the spinal cord and brain in adults , and also exists as a primitive reflex in infants . </P>
