BABINSKI SIGN:
Abnormal plantar reflex is called Babinski sign.
It is also called Babinski reflex or phenomenon. It is
named after the discoverer Joseph Babinski.
In normal plantar reflex, a gentle scratch over the outer
edge of the sole of foot causes plantar flexion and
adduction of all toes. But in Babinski sign, there is
dorsiflexion of great toe and fanning of other toes.
When Babinski reflex is present, the condition is
commonly called Babinski positive sign and when it is
negative, the condition is called Babinski negative sign.
