What is upgoing plantar response?
Definition: A reflex characterized by upward movement of the great toe and an outward movement of the rest of the toes, when the sole of the foot is stroked. It is a normal reflex up to the age of two. Its presence beyond that age indicates neurological damage.
What is the normal plantar response?
The normal plantar reflex consists of flexion of the great toe or no response. With dysfunction of the corticospinal tract, there is a positive Babinski sign, which consists of dorsiflexion of the great toe with an associated fanning of the other toes.
What are Upgoing toes?
Video: The video shows an example of a Babinski sign – upgoing toes or an extensor response when the sole of the foot is stroked. This abnormal finding suggests a lesion of the corticospinal tract (upper motor neurons) in the brain, brainstem or spinal cord.
Why is the plantar reflex important?
The Babinski reflex — also called the plantar reflex — is a response to stimulation of the bottom of the foot. It can help doctors evaluate a neurological problem in people over age 2. If your child has this reflex and doesn’t show any other signs of neurological problems, however, there’s probably no need to worry.
What causes Upgoing Plantars?
Toe extensors (extensor hallucis longus, extensor digitorum longus) are innervated by the deep peroneal nerve. Loss of normal adult descending pyramidal control of the reflex arc to suppress extensor withdrawal results in the upgoing toes in the plantar reflex known as Babinski’s sign.
What is a clonus?
Clonus is involuntary and rhythmic muscle contractions caused by a permanent lesion in descending motor neurons. Clonus may be found at the ankle, patella, triceps surae, wrist, jaw, biceps brachii.
When does Babinski reflex stop?

What causes positive Babinski sign?
A voluntary withdrawal in overtly sensitive individuals on attempting to stroke the sole of the foot.
