Hypertonia can be caused by a variety of reasons, such as craniocerebral injury, congenital developmental abnormalities, cone-bundle lesions, and lesions of the nigrostriatal system.
1. Traumatic brain injury: For example, improper use of forceps during birth, or accidental fall, which leads to brain injury, may lead to high dystocia in babies, who may show abnormal postures, such as scissor legs.
2. Inborn developmental abnormalities: for example, if the child also has a genetic metabolic disease such as hepatomegaly, it may lead to changes in the child’s muscle tone, which may cause high muscle tone.
3. Pyramidal tract lesions: for example, cerebral palsy, cerebrovascular disease, etc., may lead to motor nerve damage, which may cause increased muscle tone.
4. Nigrostriatal system lesions: commonly seen in Parkinson’s disease, which can easily lead to damage to the extrapyramidal system and the nigrostriatal system of the brain, resulting in increased muscle tone, which may also be accompanied by postural balance disorders, motor retardation and other manifestations.
It is recommended that patients with symptoms of hypertonia should consult a doctor in time and be treated under the guidance of a professional doctor to avoid adverse consequences.
