The term lumboischialgy or sciatica refers to pain that occurs after pressing the root of a large nerve that exits the spinal cord – nerve ishiadicus.

The pain may be accompanied by tingling, stiffness or weakness that starts in the lower back and left through the backside in the thigh, from the front, inside, back or outside, and can extend through the lower leg to the foot.

N. ishiadicus the longest and thickest nerve in the body, the thickness of a thumb. It is composed of five small nerves that come out of the lumbosacral spine and down the leg where it divides into smaller nerves in the upper thigh, knee area, leaf, feet and toes.sciatica

One of the easiest tests that you can apply in order to determine if indeed you suffer from sciatica is Lazarevic sign.

Lazarivic sign

This test is performed while the patient lies on her back and the doctor tries his outstretched leg lifted off the substrate.

Normal leg raise our pain up to 90 degrees, feeling the tension just below the knee.

However sciatica lifting legs causes pain in the back and leg along the sciatic nerve.

Through extensive sciatica pain is mostly limited to the affected leg.

When the pressure on the nerve root large, pain on the affected side may even increase the raise you and good leg.

The test is positive if the angle by which the lifted leg is less than 90 degrees, but due to the strong pressure on the root of the angle may be sometimes only 10, 20 or 30 degrees.

Positive Lazarevic sign, an angle greater than 60 degrees, meaning that the pressure is not great.
