What is the normal Babinski plantar response?

Explanation:
The plantar reflex tests the corticospinal tract. In a healthy adult, stroking the sole elicits plantar flexion of the toes—the toes curl downward—or they may stay neutral but do not extend upward. This is why the big toe remaining neutral or plantarflexed is the normal response. Dorsiflexion of the big toe with spreading of the other toes is the Babinski sign and points to upper motor neuron dysfunction. In infants, the reflex can appear as toe dorsiflexion with toe spreading and is considered normal for that age due to immature corticospinal pathways.
