It takes a lot of time and examinations to make the exact diagnosis that provoked pain in the spine. In 1882, the Italian physician Neri discovered a symptom that makes it possible to determine the presence of certain groups of diseases of the spine, in particular, osteochondrosis.
This method was called Nery's symptom and greatly facilitated the diagnosis, as well as the appointment of the right treatment for concomitant diseases.
What allows to identify this method of research
There is a certain number of symptoms that connect soreness in the back and extremities with the inflammatory processes occurring in the spine. This group of syndromes has received the name - symptoms of a tension. It is in this category includes the symptom of Neri.
Neri tension syndrome allows diagnosing the following diseases:
- Myeloradiculopathy is an inflammatory process in the lumbar region, in which the nerve root L5-S1 is infringed. As a result of this disease, a person is disturbed by sweating, there is a decrease or a complete lack of sensitivity of the skin. When a laboratory study of the spinal cord fluid, it is possible to detect the presence of leukocytes and red blood cells in the blood.
- Radiculitis is an inflammation affecting the spinal roots. The disease develops as a result of osteochondrosis and
can be accompanied by the appearance of neoplasms, intervertebral hernias. Radiculitis is also formed due to previous injuries in the area of the spinal column. - spasm of the lumbar muscles arises as a result of supercooling of the body. In this condition, the spinal nerves also suffer, which undergo elongation and contraction. In this case, the syndrome also manifests itself.
- Osteochondrosis 2, 3 and 4 degrees, also causes the manifestation of this symptom.
How is the
done? You can carry out this test with the help of a specialist or yourself. The patient should take a horizontal position, always on a flat and firm surface, legs are in a straight line and brought together. The doctor tries to tilt the patient's head as hard as possible, so that the patient's chin touches his chest.
With a positive Neri symptom, such a study will be accompanied by acute pain in the lumbar region. This painful condition is due to the fact that the inflammatory processes have affected the spinal nerves. The doctor looks at what angle of the head bend the most painful sensations occur in the patient. On the severity of the angle, one can judge the neglect of the disease and the effective method of its treatment.
However, you can not rely entirely on this test, since all people have different pain thresholds. The symptom helps only to reduce the list of possible diseases, accompanied by the same symptoms. The examination of the patient must be thorough and comprehensive.
As indicated by the positive test
Positive Neri tension syndrome can occur in such disorders and diseases:
- formation of bone osteophytes;
- as a result of fusion of several vertebrae;
- because of the inflammation that has arisen in the muscles and ligaments of the motor apparatus;
- if there is a protrusion of the intervertebral disc.
The manifestation of this symptom is caused by the jamming of the nerve endings in the area of the third lumbar vertebra and the first sacral vertebra.
Nerve root compression occurs when the intervertebral disk falls out and is accompanied by severe acute pain in the lower back.
And the pain can be different in nature:
- If any movement of the body, severe pain is seen in the lower back, the Neri symptom is always considered positive .The cause of acute pain lies in the infringement of nerve endings.
- Occurrence of a slight soreness lasting within 2-3 weeks, sometimes the test gives the a false-negative test. After a while, the manifestation of pain in the legs, accompanying a person during the entire development of the disease.
- As a result of the appearance of intervertebral hernia, which has a lateral direction and protrusion within 10 mm, this test probably will not show any results and then the symptom will be negative .
Neri syndrome is considered an important diagnostic measure for neurological diseases of the spine, which allows finding the cause of the disorder, determining its nature and selecting an effective treatment.
