The Babinski sign is a reflex that happens when the bottom of a persons foot is stroked and the big toe curls up in response. This reflex is usually present in babies for the first 6 or so months of their life and goes away once a certain group of nerves running from the brain to muscles in the lower limbs is fully developed and functions to block the Babinski reflex.

The Babinski can reoccur in people if this group of nerves gets damaged and is not able to block this reflex anymore. Strokes, aneurysms, and tumors are some things that can cause this.

Bilateral just means that the reflex is present in both feet.

What causes a Babinski's Reflex?

Babinski's sign is caused by a lesion in the corticospinal tract (UMN) that produces a characteristic pathological sign of extension of the great toe and fanning of the remaining toes. This also occurs in infants before the corticospinal tract is fully developed, in adults during sleep, or sometimes in adults after strenuous walking or running.

Will someone with lumbar stenosis have a positive babinski sign?

Not typical of lumbar spinal stenosis because the claudication is not affecting the descending long tracts of the spinal cord which terminates at L1.

Strokes and toes reflexes?

I believe you may be asking about the Babinski reflex. The Babinski reflex is a normal reflex for the first year or so of life, when the brain is not fully myelinated. It is an upward extension of the big toe and a fanning out of the remainder of the toes. As was mentioned earlier, this reflex normally goes away by the first year of life and when one tries to elicit the response after it goes away, one should see a downward flexion of the toes. In stroke (or spinal cord injury) involving the leg, the Babinski reflex may come back. This is a sign of upper motor neuron injury. The injury can be anywhere from the cerebral cortex to the spinal cord, so a Babinski reflex by itself does not signify stroke.
