Oppenheim’s Sign

Oppenheim’s Sign

Oppenheim’s sign is a variant method for eliciting the plantar response, by application of heavy pressure to the anterior surface of the tibia, for example with the thumb, moving from patella to ankle. Extension of the hallux (upgoing plantar response, Babinski’s sign) is pathological. Like Chaddock’s sign, Oppenheim’s sign always postdates the development of Babinski’s sign as a reliable indicator of corticospinal pathway (upper motor neurone) pathology.
