Q. What does it mean if Babinski is present?
When the Babinski reflex is present in a child older than 2 years or in an adult, it is often a sign of a central nervous system disorder. The central nervous system includes the brain and spinal cord. Disorders may include: Amyotrophic lateral sclerosis (Lou Gehrig disease)
Q. What is an abnormal Babinski response?
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.

Q. 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.
Q. What is the clinical significance of Babinski reflex?
Clinical Significance The presence of the Babinski reflex is indicative of dysfunction of the CST. Oftentimes, the presence of the reflex is the first indication of spinal cord injury after acute trauma.
Q. What is a positive Babinski test?
In adults or children over 2 years old, a positive Babinski sign happens when the big toe bends up and back to the top of the foot and the other toes fan out. This can mean that you may have an underlying nervous system or brain condition that’s causing your reflexes to react abnormally.
Q. What is triple flexion response?
DISCUSSION. The Triple Flexion Reflex or Response (TFR) is defined as flexion of the thigh, leg, and dorsiflexion of the foot upon noxious stimulus of the foot.1 In 1881 it was. described by Sherrington in dogs.2 In 1896 Babinski described it in humans as.
Q. Why does UMN lesion cause Hyperreflexia?
Hyperreflexia. Because of the loss of inhibitory modulation from descending pathways, the myotatic (stretch) reflex is exaggerated in upper motor neuron disorders. The stretch reflex is a major clinical diagnostic test of whether a motor disorder is caused by damage to upper or lower motor neurons.
Q. Does ALS cause a positive Babinski?
Other authors have reported similar frequencies of Babinski sign (50%) in patients with ALS. According to the literature, hyperreflexia and spasticity are frequently difficult to detect or may even be absent in these patients due to weakness and muscle atrophy.
