A positive Babinski sign in an adult is considered to be:

• A. A norm finding
• B. An abnormal finding
• C. A sign of deep tendon reflexes
• D. A sign of normal cerebellar function

Answer: (B)

A positive Babinski sign in an adult is considered an abnormal finding because it indicates potential damage to the corticospinal tract or other brain areas involved in motor control. The Babinski reflex is a primitive reflex that should normally be suppressed in adults; instead, they typically exhibit a negative response, where the toes curl downward when the sole of the foot is stimulated. A positive response, characterized by the big toe extending upward and the other toes fanning out, suggests that the neurological pathways responsible for reflexes are functioning abnormally, often associated with neurological conditions such as multiple sclerosis, amyotrophic lateral sclerosis, or other upper motor neuron lesions. Therefore, the presence of a positive Babinski sign warrants further neurological assessment and investigation to determine the underlying cause.
