I. Diagnostic points 1, with conscious symptoms such as spinal pain, spinal mobility disorders, pain, swelling, numbness, corresponding organ dysfunction and one or several other manifestations. 2.Visual examination From the patient’s upper atlanto-occipital joint down to the coccyx in the internal and external to the inner edge of the scapula line carefully look at the midline of the spine and the spine on both sides of the spine whether there is scoliosis, depression of the spinous process or convexity deviation or deviation from the midline of the spine zone pigmentation changes. 3, palpation Using the three-finger palpation method can find spinal thickening, pressure pain, deviation from the midline and the spine related muscles, ligament attachment points, there are obvious spasm, thickening, striated or sand-like hard nodes, peeling, friction sounds and other positive reactive objects. 4.X-ray and other auxiliary examinations There are more than one supporting the diagnosis of spinal syndrome early subluxation auxiliary examination is difficult to find with palpation plus conscious symptoms can confirm the diagnosis. 5. Consultation with various specialties Exclude fractures, subluxations, tumors, tuberculosis, eosinophilic granuloma and serious organic lesions. 6.Laboratory examination to exclude inflammatory rheumatism and other factors. 1. The first step is the nerve localization diagnosis method. During the consultation, the patient’s pain and numbness are analyzed according to the nerve localization diagnosis to initially identify the misaligned vertebrae or joints. 2.The second step is to look at the shape of the spine and observe whether there is any distortion, depression or protrusion of the spine area with skin color change and pigmentation. 3.The third step of palpation is to determine whether there is any distortion of the spinous process, kissing spine, whether there is any misalignment of the articular process, frictional sound, popping sound, transverse pressure pain, and whether there are positive reactions such as hard nodes, cords, or compensatory hypertrophy, etc. by three-finger palpation. The diagnosis of spinal subluxation can be further clarified by three steps of palpation in line with the first two visualizations and neurological examination results in line with the first and second steps of localization. 4, the fourth step of the spinal image positioning method First of all, carefully observe the changes in the intervertebral joints of the X-ray lateral film, the dynamics of the vertebral axis changes, whether the physiological curvature is straightened, whether there is anti-arch, whether the posterior edge of the laterally curved vertebral body is sharpened, whether there is a bone bridge formation atlantoaxial subluxation will appear when the supination, tilt, lateral rotation and other changes, the intervertebral joint morphology changes or displacement are the manifestation of spinal subluxation. The final localization diagnosis can be made by the comprehensive analysis of the disc degeneration, vertebral joint osteophytes, the site and degree of calcification of each ligament and the first three steps of localization diagnosis. Attention should be paid to exclude fractures, dislocations, tuberculosis, tumors, septic inflammation, etc. Palpation method 1, single finger palpation method The thumb is used as the pressure point to slide the local tissue for palpation to observe whether there is local tissue tension, pressure pain, nodules, cords, etc.. It is mainly used to diagnose soft tissue injury diseases. 2.Three-finger palpation method The tips of the finger bellies of the index finger, middle finger and ring finger are pressed on the three prominences of the spine up to the crico-occipital joint and down to the tip of the coccyx. Outside to the lateral side of the erector spinae muscle from the top to the bottom and from the inside to the outside, the three-finger palpation method uses a certain pressure to slide from the top to the bottom and from the inside to the outside, carefully touching whether the line of each spinous process is straight or not, and whether there is any distortion, hypertrophy and pressure pain in each spinous process. It is mainly used to diagnose spinal lesions and spinal-related diseases. 3.Finger point test The patient is asked to point out the pain site accurately with one finger in order to understand the pain site and the size of the pain range. If the location of the finger point is clear and repeated several times, the location of the finger point remains unchanged, indicating that there may be organic lesions or injuries in this area. On the contrary, if there is no definite pain location, it means that there is no organic lesion or injury.
