The Babinski reflex (or sign), which is assessed during neurological examination, can be tested by using a finger or blunt object to stroke the sole of the foot along the lateral side, from the heel to the toes. Dorsiflexion of the big toe and plantar flexion and spreading of the small toes indicate a positive Babinski sign. This sign is positive in infants until 12–24 months of age. Afterwards, a positive Babinski sign may indicate damage to the corticospinal tract. Full video available here: h

The Babinski Reflex is a reflex that should go away at about a year old, before a child begins to walk. Typically, when you see this reflex, their toes will splay out and come up when you stroke the bottom of the foot. If this reflex does not go away it often creates toe walking or hypersensitiveness in the feet. Disclaimer: this video is not intended to cure or treat any condition or disease.
