Is a positive Babinski reflex a common symptom of post-polio?



Answers:
No.

The Babinski reflex is abnormal in adults (it's normal in young babies) and involves the toes spreading and curling up on stroking the bottom of the foot.

The reflex, if present in adults, indicates an abnormality of the corticospinal tract - i.e. of the upper motor neurons that run from brain to the spinal cord.

Polio on the other hand knocks out the lower motor neurons that run from the spinal cord to the limbs. So polio will not cause a positive Babinski reflex.

It can be sometimes a little difficult to tell - a lot of people find the Babinski test a very uncomfortable procedure and will therefore reflexly withdraw their foot, which can look like a positive Babinski.

Common, no. Also, it depends on the depth/scope of the polio infection.
I think it's a sign of meningitis, no?
a positive Babinski is a sign of an upper motor neuron lesion.and i don't think polio is an upper motor neuron

an upper motor neuron usually involves the brain.someone who has had a stroke or a traumatic brain injury will have a + babinski

so if the polio virus went to the brain then yes they could have a + babinski.
