Torsion spasms are mostly seen in school-age children and adolescents, the onset of most of the age of 5-15 years old slow onset of the disease, clinical symptoms are mainly manifested as generalized dystonia and around the trunk of the slow and violent rotational involuntary torsion. The disease often brings great impact on the physical and mental health of the affected children, but also a great burden on the patient’s family. Many people do not understand the disease of torsion spasm, so in the medical treatment took a lot of detours, J today for everyone to popularize the knowledge of torsion spasm. 1, the main clinical symptoms: the main symptom of torsion spasm is dystonia, the muscles are not under the control of the patient’s voluntary contraction, resulting in the trunk, limbs and even the whole body violent twisting, trembling, posture is not normal and other symptoms. Can also be manifested by frowning, pulling the mouth crooked tongue, blepharospasm, torsion and a variety of involuntary movement of the limbs. Disease classification: There are two types of primary and secondary, and Marsden categorized primary into generalized, segmental and focal. Systemic type: the symptoms gradually spread from the starting site to the limbs and trunk. Segmental: Symptoms involve a limited range of areas, such as one upper limb and neck, or both upper limbs, neck and trunk, but not the lower limbs. Focal type: the symptoms are limited to the site of onset, such as the upper limbs or feet, but it is rare. Primary torsion spasms are partly caused by genetic factors, and secondary spasms can be caused by, for example, cerebral hypoxia, cranial trauma, hepatomegaly, encephalitis, or drug reactions. It occurs in people with family history, carbon monoxide, organophosphorus insecticide poisoning, etc. Infection, poisoning, trauma, etc. can induce torsion spasm. 4. How to treat? There is no specific treatment for torsion spasm, and most of them cannot be cured. However, effective standardized treatment can alleviate the condition and help patients improve their quality of life. At present, the main treatment is drug therapy, such as: levodopa, anticholinergic drugs, γ-aminobutyric acid drugs and so on. Localized dystonia can be treated by injection of botulinum toxin. Surgery will be considered only when the effect of medication is unsatisfactory and the condition seriously affects the patient’s quality of life. Brain pacemaker surgery can effectively relieve dystonia and improve the symptoms of patients with torsion spasms. Moreover, brain pacemaker has the advantages of reversibility and adjustability without permanent damage to the tissues, especially for children patients whose brain development is not yet complete. Unilateral surgery or bilateral simultaneous implantation of electrode stimulation can be performed to improve the patient’s mobility in daily activities and improve the quality of life.
