Babinski's sign in a healthy newborn. The Babinski sign can indicate upper motor neuron lesion constituting damage to the corticospinal tract.Occasionally, a pathological plantar reflex is the first and only indication of a serious disease process and a clearly abnormal plantar reflex often prompts detailed neurological investigations, including CT scanning of the brain or MRI of the spine, as ...
Pyramidal signs indicate that the pyramidal tract is affected at some point in its course. Pyramidal tract dysfunction can lead to various clinical presentations such as spasticity , weakness , slowing of rapid alternating movements, hyperreflexia , and a positive Babinski sign .
In Babinski's sign, there is dorsiflexion of the big toe and abduction of the other toes. Physiologically, it is normally present in infants from birth to 12 months. The presence of the Babinski sign after 12 months is the sign of a non-specific upper motor neuron lesion. Increased deep tendon reflex (DTR) Pronator drift [3]
A positive Babinski sign is considered a pathological sign of upper motor neuron disease except for infants, in whom it is normal, [7] whereas a positive Hoffmann's sign can be present in an entirely normal patient. A positive Hoffmann's sign in the normal patients is more commonly found in those who are naturally hyper-reflexive (e.g. 3 ...
(A) He needs assistance to stand. (B) Advanced atrophy of the tongue. (C) There is upper limb and truncal muscle atrophy with a positive Babinski sign. (D) Advanced thenar muscle atrophy. [8] Signs and symptoms depend on the specific disease, but motor neuron diseases typically manifest as a group of movement-related symptoms. [6]

A positive Babinski sign may be seen. [7] Prolonged deficiency of vitamin B 12 leads to irreversible nervous system damage. HIV-associated vacuolar myelopathy can present with a similar pattern of dorsal column and corticospinal tract demyelination. [citation needed]
Upper motor neuron signs—weakness, spasticity, clumsiness, altered tonus, hyperreflexia and pathological reflexes, including Hoffmann's sign and inverted plantar reflex (positive Babinski sign) Lower motor neuron signs—weakness, clumsiness in the muscle group innervated at the level of spinal cord compromise, muscle atrophy, hyporeflexia ...
