A method for eliciting the extensor plantar response by stimulating the lateral aspect of the foot, beginning about under the lateral malleolus near the junction of the dorsal and plantar skin, drawing the stimulus from the heel forward to the small toe. Babinski’s plantar sign is the mainstay of extensor toe signs seen in patients with lesions of the corticospinal tract, the most useful variation is Chaddock’s sign. The response of the toes is the same as with the Babinski. It is occasionally possible to elicit one or more of the alternate extensor toe signs, especially the Chaddock, when the Babinski cannot be obtained.
