Hypertonia may be caused by neurological insufficiency or a disease of the nervous system, and hypertonia can cause physical motor dysfunction. High muscle tone is mainly characterized by stiffer muscles, increased resistance to passive movement, and reduced range of motion of joints. There are many causes of high muscle tone, commonly cone system and extrapyramidal lesions, such as sequelae of cerebrovascular disease and Parkinson’s disease. Treatment of hypertonia can begin with, taking the appropriate body position. Reduce or eliminate the factors that cause hypertonia, such as constipation, bladder distension, unsuitable sitting and posture. Increasing more mobile joint training is the most basic way to deal with hypertonia. It can also be treated with physical methods, such as neurobiofeedback therapy, heat therapy, functional electrical stimulation and other physical therapies. Oral medications to reduce muscle tone, such as baclofen, levodopa, ethylprednisolone hydrochloride, clonazepam, etc., can also be administered. Surgical treatment such as partial tendonotomy, selective dorsal root neurotomy, and pharmacological blockade can also be performed. Local botulinum toxin injection therapy, anhydrous alcohol nerve stem injection therapy, etc. can also be considered as appropriate. In conclusion, the treatment of hypertonia should be treated according to the etiology of its primary disease, and the appropriate treatment should be taken according to the different etiologies.
