Step 1: Neurolocalization diagnosis (symptom presentation site): When asking about the condition, according to the site of pain and numbness (for those without numbness and pain, according to the organ site of the main symptom), analyze the damage site of the spinal nerve root according to the neurolocalization diagnosis, and initially determine the spine or joint of the disease. 1. For limbs with numbness and pain, a preliminary diagnosis of the spinal range of onset was made according to the distribution of peripheral nerves. For example, for supraventricular tachycardia, check whether the cervical sympathetic segment (the supra-cervical cardiac branch is an accelerating nerve) is located in cervical vertebrae 1-3 for misalignment or pressure pain. 3. For those with localized spinal symptoms, in addition to examining the spine, check whether the innervated muscles and ligament attachment points are strained. The second step: palpation and diagnostic localization method: Based on the results of the spinal examination performed by the operator, including the discovery of the transverse process, spinous process and articular process deviation, paravertebral pressure pain, the site of positive pathological reactions (hard nodes, friction sounds, popping sounds, muscle atrophy or compensatory hypertrophy, etc.), or the results of various tests and neurological examinations combined with the first step of localization diagnosis, a second localization diagnosis is performed to further determine the spine, joint and subtype of the disease. joint and subtype. 1, transverse process and articular process palpation method: The operator uses the right thumb and index finger to lightly place the posterior cervical transverse process and articular process of the patient (first touch the first cervical transverse process from the tip of the mastoid process, then move downward posteriorly to the posterior articular process of the 2nd and 3rd cervical vertebrae), slide up and down to compare, and palpate whether the articular process is elevated and whether the transverse process is symmetrical to the left and right. If there is any abnormality, it should be checked whether there is also pressure pain and pathologically positive reactive material? If there is, it is a sign of small joint misalignment, if not, it is a congenital deformity. (Since the cervical spine processes are mostly bifurcated and of different lengths, palpation is prone to errors, so it is better to check the transverse synovial synapse.) 2.Spinous process palpation method: used for the examination of the lower cervical and thoracic spine. If the spine is uneven and distorted, the transverse process palpation method is also used to identify whether the deformity is present or congenital. 3, positive reactive object palpation method: the operator with the thumb in the affected vertebral spinous process, transverse process, joint synapse up and down rubbing palpation, and check the distal attachment point of the muscle connected with the affected vertebrae for friction sounds, pressure pain and hard knots. If so, this is a point of strain or a reactor of injury (e.g., aseptic inflammation or myospasm). Step 3: X-ray cervical spine photograph localization diagnosis: Observe the changes in the intervertebral relationship, spinal axis variation, and vertebral body posterior margin association variation in the cervical spine X-ray. Changes such as supination, tilt, supination rotation, tilt rotation and lateral rotation that occur when the circumferential vertebrae are misaligned. The morphology or displacement of each intervertebral joint is a manifestation of cervical joint misalignment. Observe the degeneration of each intervertebral disc, osteophytes of the intervertebral joint, and the site and degree of calcification of each ligament. And combined with the first and second step localization diagnosis analysis, to make the final localization diagnosis results. 1.Exclude spinal tumor, tuberculosis, fracture, dislocation and rheumatoid, gout and other diseases. 2.Analyze the site, direction (type) of intervertebral joint misalignment, and CT examination is feasible for those with disc herniation 3.Analyze the degree of disc degeneration (early and middle stage can be treated by orthopedic method under traction), and the relationship between the site of osteophytes and the symptomatic site. 4. Observe the intervertebral joints for inflammation, osteoporosis and calcification sites to provide reference for treatment. Not suitable for chiropractic treatment: spinal tumors, tuberculosis, fractures, dislocations, local septic lesions, bleeding tendencies and various critical patients.
