Lasègue's sign is defined positive if the patient experiences a typically dermatomal area of pain reproduction and pelvic muscle resistance below a unilateral 60 degrees angle provocative straight leg raising. 'Crossed positive' if the same experience was noted with straight raising of the contralateral leg below 90 degrees.
