Femoral nerve stretch test (Mackiewicz sign[1]) - for the FNST the patient lies prone, the knee is passively flexed to the thigh and the hip is passively extended(reverse Lasegues); the test is positive if the patient experiences anterior thigh pain. This test is usually positive L2-L3, L3-L4(high lumbar), slightly positive or negative in L4–L5 disc protrusions and negative in cases with a lumbosacral protrusion.
