Myotonia is the degree of muscle tension in the resting, relaxed state, called muscle tone, which is the basis for maintaining various postures of the body as well as normal movement, and reasonable muscle tone is necessary for performing exercise. When muscle tone is abnormal, it leads to abnormal posture and various movements. Muscle tone is clinically abnormal and categorized as either increased muscle tone or decreased muscle tone. In terms of the etiology of neurological disorders, clinical causes of increased muscle tone mainly include diseases of the pyramidal system and diseases of the extrapyramidal system. The first one is conus system disease, which is mainly common in spinal cord and brain diseases, such as common clinical spondylitis, spinal cord trauma, spinal cord tumor, cervical spondylosis, traumatic brain injury, cerebral hemorrhage, etc. If these causes lead to dystonia, then the cause of dystonia will be the spinal cord and the brain. If the increased muscle tone is caused by these reasons, it is often necessary to treat the original disease, such as spinal cord tumors caused by spinal cord tumors, may need to do spinal cord tumor resection; if it is caused by spinal cord cervical spondylosis, it is possible that the cervical spondylosis surgery and so on. The second is the extrapyramidal cause, extrapyramidal system diseases lead to increased muscle tone, this kind of patients often have the characteristics of lead pipe-like or cogwheel-like ankylosis, usually use drugs to control the treatment, such as the use of dopamine receptor agonists or amantadine drugs to control.
