What is a normal plantar reflex?
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 reflex occurs when the sole of the foot is touched?
The Babinski reflex occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot. The other toes fan out. This reflex is normal in children up to 2 years old.
What does an abnormal plantar reflex signify?
The abnormal plantar reflex, or Babinski reflex, is the elicitation of toe extension from the “wrong” receptive field, that is, the sole of the foot. Thus a noxious stimulus to the sole of the foot produces extension of the great toe instead of the normal flexion response.
What happens during a plantar reflex?
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 healthy adults, the plantar reflex causes a downward response of the hallux (flexion).
Why do doctors check the bottom of your feet?
The Babinski reflex is a reflex response in the bottom part of the foot. It occurs as a reaction to stroking the sole of the foot with a blunt object. The Babinski reflex is one part of the neurological testing that doctors use to check for healthy development or underlying neurological conditions.
What does Babinski reflex test for?
The Babinski reflex tests the integrity of the corticospinal tract (CST). The CST is a descending fiber tract that originates from the cerebral cortex through the brainstem and spinal cord. Fibers from the CST synapse with the alpha motor neuron in the spinal cord and help direct motor function.
What does it mean if you don’t have any reflexes?
When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged. When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.
What causes reflexes in the sole of the foot?
The reflex occurs upon stroking of the sole of the foot with a sharp object such as a pen. If the reflex occurs in adults as illustrated at bottom it may be due to nerve damage or disease.
When does the Babinski reflex occur in the foot?
Reflexes are responses that occur when the body receives a certain stimulus. The Babinski reflex occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot. The other toes fan out.
Which is the correct description of the plantar reflex?
The abnormal plantar reflex, or Babinski reflex, is the elicitation of toe extension from the “wrong” receptive field, that is, the sole of the foot. Thus a noxious stimulus to the sole of the foot produces extension of the great toe instead of the normal flexion response.
