What is the direct lifting of the foot?

Direct leg lifting is a test used by a doctor who helps to determine whether suffering pain in the lower back occurs symptoms in accordance with the hernified disc in the spine. The herniated disc occurs when the backbone disc, which is a gel capsule located between the vertebrae, begins to bulge and push against different nerves. A direct increase in the foot is only one test used to determine whether the patient suffers from a herniated disc; This in itself cannot be used as a positive determination.

In order to test the straight leg, the patient will lie on his back with his legs placed together and his arms on his side. The test can be performed in two different ways: it can be performed in a passive manner or actively. In the passive test, the doctor catches on the patient's leg and lifts it with a straight knee. In the active test, a similar movement occurs, but the patient actively raises her leg rather than relying on the doctor to lift his leg. The test results depend on whether the patient feels some pain in the direct foot.

nerve pain is the most common type of pain that feels during a straight leg. The ischiatic nerve runs from the lower back to down the back of each foot and is very often affected when the disc is noted. Pain in the legs, legs, buttocks or even lower back may occur as a result of a herniated disk; A direct increase in the foot is a test used to determine whether the seating nerve is compressed or otherwise damaged due to a herniated disc.

The medical expert must be present to interpret the test results. If the pain is felt when the leg is bent between 30 and 70 degrees, it is probable Mark, the basic cause of pain will probably be something other than a hernified disk. The spinal nerve root is stretched during exercise, but usually until the leg reaches 30 degrees. If pain is felt before, the nerve root has not been sufficiently stretched and therefore does not cause pain yet.
