Babinski's reflex occurs when the big toe moves toward the top of the foot and the other toes fan out after the sole of the foot has been firmly stroked.
Reflexes are specific, predictable, involuntary responses to a particular type of stimulation.
Babinski's reflex is one of the infantile reflexes. It is normal in children up to 2 years old, but it disappears as the child ages and the nervous system becomes more developed. It may disappear as early as 12 months.
The presence of a Babinski's reflex after age 2 is a sign of damage to the nerve paths connecting the spinal cord and the brain (the corticospinal tract). This tract runs down both sides of the spinal cord, therefore a Babinski's reflex can occur on one side or on both sides.
An abnormal Babinski's reflex can be temporary or permanent.
Thanks for the reply but the question was if the four toes spread apart but the big toe doesnt move at all is that a posotive babinski sign.
Well Selma has answered your Question....
positive Babinski's reflex or Babinski's sign = big toe pointing up
