Lasegue Test

October 30, 2017

A test of the low back used by spinal care health providers in which the hips are passively flexed with the knee in full extension. A positive test produces low back or sciatic pain prior to reaching 90 degrees of hip flexion and no pain when the hip is flexed with the knee bent. Synonymous with straight leg raise test. This test helps to distinguish low back disorders from disease of the hip joint.
