Babinski's sign

An extension and fanning out of the toes when the sole of the foot is stroked firmly with a pointed object. This reaction, instead of the normal curling up of the toes, indicates damage to the motor system above the level of the spinal nerves and is common in STROKE. (Joseph François Babinski, 1857–1932, French neurologist).
