Traction of sciatic nerve can induce pain or aggravate pain, such as positive Kernig sign and positive straight leg raising test (Lasegue sign).

Pain often radiates from the hip to the back of the thigh, the posterolateral side of the leg and the lateral side of the foot. The pain aggravated when walking, moving and drawing sciatic nerve. The tenderness point was below the gluteal point, Lasegue sign was positive, while Kernig sign was negative. Scoliosis was often bent to the affected side to reduce the traction of sciatic nerve trunk.

There are different degrees of motor, sensory, reflex and autonomic nerve dysfunction. The results showed that the dorsal flexion of the affected toe was weak, the skin pain of the lateral leg decreased, the Achilles tendon reflex disappeared, and the gluteal muscle tension decreased.
