Babinski Sign
Babinski Sign (pronounced: ba-bin-skee sign) is a clinical test used in neurology to detect damage to the central nervous system. It is named after the French neurologist Joseph Babinski, who first described the phenomenon in 1896.
Etymology
The term "Babinski Sign" is derived from the name of its discoverer, Joseph Babinski. Babinski was a prominent neurologist in the late 19th and early 20th centuries, known for his extensive research on the human nervous system.
Definition
The Babinski Sign is a physical examination finding where, when the sole of the foot is stroked, the big toe moves upward or toward the top surface of the foot and the other toes fan out. This is an abnormal response and can indicate damage to the central nervous system.
