Hypertonia is mainly characterized by relatively stiff muscles, increased resistance to passive movement, and restricted or reduced range of joint motion. There are many causes of hypertonia, the common ones being cone system and extrapyramidal pathology. Parkinson’s disease, for example, is one of the more obvious cases of hypertonia. Hypertonia manifested as muscle stiffness will have vertebral tract injuries. Hypertonia occurs after damage to the nerves that govern limb movement and is considered to be damage to the conus pallidus bundle of the brain. There are many clinical causes of hypertonia, including neurological disorders of the brain, as well as some traumatic or organic occupational disorders. When the body is deficient in certain elements such as calcium, it is also likely that transient hypertonia with pain, called painful spasms, will occur. Therefore, it is important to take calcium supplements in a timely manner. In addition, anticholinergic drugs, muscle relaxants such as baclofen, ethylprednisolone, tizanidine, etc. and sedative sleeping pills can be used for treatment as appropriate, but these can only relieve the symptoms, and the primary cause must be treated if the disease is to be completely resolved. In short, high muscle tone will cause the body motor dysfunction, only symptomatic treatment. Only with the right treatment is it possible to improve the body’s functions.
