| Summary: | Background: To suggest a new way of eliciting pyramidal tract dysfunction in adults since the most widely utilized plantar reflex, which is the Babinski reflex, has limitations with different reliability and consistency among different examiners.  Materials and methods: 168 adult subjects were examined for the new sign in addition. It consists of just an observation of the patient’s feet and toes in a conscious patient looking for the extension of the great toe along with fanning, spreading and plantar flexion of the small toes either at rest or when patient elevates one leg up at a time. Results: We were able to observe the extension of the great toe along with fanning, spreading and plantar flexion of the small toes in patients with impairment of pyramidal tract. The specificity was 94% while the sensitivity was 96%. Conclusion: Pyramidal tract lesion in adults can be elicited by this new test that observes the extension of the great toe along with fanning, spreading and plantar flexion of the small toes in patients. We suggest this sign as a complement to established signs like Babinski reflex.
