This reflex is commonly used to test the function of the nervous system, and abnormal responses may indicate certain neurological conditions. There are a few synonyms for plantar reflex such as the Babinski sign, the plantar response, and the extensor plantar response. Babinski sign is named after the French neurologist Joseph Babinski, who first described this phenomenon in 1896. The term plantar response is a general term that refers to any reflex that involves the sole of the foot. Extensor plantar response is another name for the Babinski sign, as it involves the extension of the toes.
