Is Babinski positive or negative?
The Babinski reflex is known by a number of other names: the plantar response (because the sole is the plantar surface of the foot), the toe or big toe sign or phenomenon, the Babinski phenomenon or sign. (It is wrong to say that the Babinski reflex is positive or negative; it is present or absent).
What does a positive Babinski sign mean?
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.
What is a positive Babinski sign?
Positive Babinski sign occurs when stimulation of lateral plantar aspect of the foot leads to extension (dorsiflexion or upward movement) of the big toe (hallux). Also, there may be fanning of the other toes. This suggests that there is been spread of the sensory input beyond the S1 myotome to L4 and L5.
What is the Babinski reflex test?
The Babinski reflex test is done as part of the routine neurological exam and is utilized to determine the integrity of the cortical spinal tract. The presence of a Babinski sign suggests damage to the cortical spinal tract. Because the cortical spinal tract fiber tracts run from the brain, through the brainstem and into the spinal cord, lesions of the central nervous system (CNS) often affect the integrity of the cortical spinal tract. Thus, the presence or absence of the Babinski reflex can provide very useful information on the presence or absence of pathology affecting the central nervous system. Babinski reflex is especially important in the setting where there is suspicion of spinal cord injury or stroke, as it may be an early indicator of the presence of these emergency conditions 12).

Where does the Babinski sign originate?
The remainder originates from primary sensory areas, the parietal cortex, and the operculum. Damage anywhere along the cortical spinal tract can result in the presence of a Babinski sign.
Where does nociceptive input travel?
Nociceptive input travels up the tibial and sciatic nerve to the S1 region of the spine and synapse with anterior horn cells. The motor response which leads to the plantar flexion is mediated through the S1 root and tibial nerve. The toes curl down and inward. Sometimes there is no response to stimulation.

The motor response which leads to the plantar flexion is mediated through the S1 root and tibial nerve. The toes curl down and inward. Sometimes there is no response to stimulation.
Can a Babinski reflex test be performed in patients who are otherwise unable to cooperate with the neurological exam?
Since it is a reflex, it does not require active patient participation and therefore can be performed in patients who are otherwise unable to cooperate with the neurological exam. This activity describes the technique for performing the Babinski reflex test and how to interpret the results.
