Positive signs in cervical spondylosis can be triggered and detected in neurogenic cervical spondylosis and spinal cord cervical spondylosis, and the following positive signs can be detected in neurogenic cervical spondylosis: First, the pressure neck test, the pressure neck test is that the patient’s head is tilted to one side and tilted back when sitting in the end position, when the pressure head can appear ipsilateral upper limb radioactive pain, which is a symptom of nerve root compression. Brachial plexus pull test and it is the opposite result, pulling one side can cause the ipsilateral nerve compression symptoms to reduce, thus reducing the symptoms of numbness in the hand. Second, there is skin sensory disorder in the corresponding area, and there are different areas of skin sensory disorder according to different segments of cervical spondylosis. The following positive signs can be detected during physical examination of spinal cervical spondylosis: sensory planes and muscle strength are reduced, tendon reflexes of the extremities can be detected to be more active and hyperactive, physiological reflexes such as abdominal wall reflex, testicular reflex and anal reflex can be weakened or disappeared, and positive signs of pathology such as patellar clonus and ankle clonus can appear, which is highly suspected to be caused by cervical spondylosis.
