Schaefer’s sign: Explained

Schaefer’s sign is a variation of Babinski's reflex
The sign is described by the German neurologist Max Schaeffer (1852-1923).
Method of elicitation Schaefers sign
Schaeffer's sign is a clinical sign in which the examiner squeeze  the Achilles tendon of patient to elicits an extensor plantar reflex.

Clinical significance 
  • It is found in patients with pyramidal tract lesions
  • The method of Babinski is probably the most sensitive and reliable method for elicitation of the plantar reflex, but sometimes it may fail to do so or produce an equivocal response
  • These reflexes show a positive Babinski response when the reflexogenic area spreads up in the lower limb.
  • They may be useful in eliciting the Babinski response when the patients are uncooperative or in patients whose soles are extremely sensitive
