What examination does sciatica need to do

summary

It's common sense that my legs and feet will cramp after sitting for a long time, but recently I feel numb after sitting for 2 hours, and the feeling of waist pain always exists. I went to the hospital to check that I have sciatica. After seeing the doctor, the situation seems to be better. Do you know what kind of check-up should be done for sciatica? Let's talk about what examination should be done for sciatica.

What examination does sciatica need to do

First: preliminary examination: observe whether the patient has limp, duck step and foot drop when walking; whether the spine has deformity or scoliosis when standing upright, whether the lumbar spine is straight, whether the back muscles on both sides are symmetrical, whether the pelvis is inclined, etc.; whether the spine is restricted when doing forward flexion, backward extension, lateral flexion and rotation, and whether there are tenderness points along the direction of the sciatic nerve. After preliminary examination, we can judge whether the patient has sciatica.

Second: test examination: whether the sciatic nerve traction test, such as straight leg raising test, neck flexion test, cross straight leg raising test, bowstring test, piriform muscle tension test, is positive. And physical examination of sensation, movement and reflex can basically judge which type of sciatica the patient is.

Third: instrument examination: in order to accurately determine the cause of sciatica, it is necessary to do the corresponding X-ray examination, first take the anteroposterior and lateral film, and then take the oblique film and functional film according to the situation. If the diagnosis is difficult, lumbar puncture can be done to check cerebrospinal fluid, myelography, CT, MRI, EMG and nerve conduction velocity.

matters needing attention

Here I would like to give you a warm reminder: now office workers work seven or eight hours a day, and seldom exercise at work, resulting in sciatica. Due to the increase of work pressure in daily life, many diseases come to our door, among which sciatica is a common, mainly due to the bad habits in our daily life. Bad sitting posture will cause sciatic nerve to a certain extent, so we must maintain a good sitting posture to prevent the occurrence of sciatic nerve.
