is raised (extended) rather than curled downwards (flexed) upon appropriate stimulation of the sole of the foot. The presence of the
Babinski sign is an abnormal response in adulthood. Normally, during the plantar reflex, it causes plantar flexion and the adduction of the toes. In Babinski's sign,

there is dorsiflexion of the big toe and abduction of the other toes. Physiologically, it is normally present in infants from birth to 12 months. The presence of the
Babinski sign after 12 months is the sign of a non-specific upper motor neuron lesion.
