Whereas Positive Babinski sign demonstrates pathological condition in the spinal cord and brain. It is not demonstrated in a normal patient but sometimes the term ‘Negative Babinski sign’ is used for them. NettetThe reflex is an automatic response to a stimulus that does not receive or need conscious thought as it occurs through a reflex arc.
