[[Lasègue's sign]] was named after [[Charles Lasègue]] (1816-1883).

In [[1864]] Lasègue described the signs of developing low back pain while straightening the knee when the leg has already been lifted. In [[1880]] Serbian doctor Laza Lazarević described the straight leg raise test as it is used today, so the sign is often named Lazarević's sign in Serbia and some other countries.
