Torsion spasticity is a dystonic disorder that seriously affects life, work and study. Patients with early onset of the disease with unclear symptoms can easily be misdiagnosed or delayed, leading to aggravation of the disease. The onset of torsion spasticity is usually in childhood, usually with a family history, normal birth and developmental history, and manifests mild motor deficits in one or both lower limbs, inversion of the foot, inability to land on the heel when walking, followed by involuntary twisting movements of the trunk and limbs, leading to severe dysfunction. The twisting or spiral movement of the whole body is the characteristic manifestation of the disease. What are the symptoms of torsional spasm? 1. Slow onset, mostly starting from the lower extremities and expanding to the trunk and extremities. Myotonia episodically increases, characterized by involuntary twisting parallel to the longitudinal axis of the muscle, the proximal end is heavier, resulting in plantar inversion of the foot, head, neck and trunk spiral twisting, and can be accompanied by eyebrow squeezing, crooked mouth tongue and other movements. The symptoms can also be limited to a certain part of the torso, and those occurring in the cervical muscles are called spastic diagonal neck. The symptoms are mostly triggered or aggravated by mental tension or walking, and disappear during sleep. 2.Except for secondary cases, the intermittent neurological system is normal, and a few have diminished intelligence. 3.In addition to primary cases (common in 8-15 years old), it can be caused by cranial trauma, infection, carbon monoxide poisoning, drugs (such as haloperidol), hepatomegaly, etc. Occasionally, it is also seen in vascular disease and brain tumor. With the corresponding medical history, symptoms, signs and auxiliary examinations, the treatment is mainly pharmacological and surgical. Doctors introduce that for patients with severe torsion spasms for whom pharmacological treatment is ineffective, brain pacemaker implantation can be chosen to treat torsion spasms, and DBS can effectively relieve dystonia and improve the symptoms of patients with torsion spasms. Moreover, DBS has the advantages of reversibility and modifiability, with no permanent damage to tissues, and is especially suitable for pediatric patients whose brain development is not yet complete.
