Babinski reflex test & causes of positive Babinski reflex in adults

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

Science on Instagram: "The Babinski reflex is a natural neurological response in infants. When the sole of a baby’s foot is gently stroked, the big toe extends upward while the other toes fan out. This might look strange, but it's actually a sign of a healthy, developing nervous system! In adults, this same response may indicate neurological issues — but in babies, it's completely normal and expected until around 2 years of age. . . . #BabinskiReflex #InfantReflexes #NeurologyFacts #HumanBodySci
