Twisting spasms most often develop in childhood, usually with a family history, normal birth and developmental history, and manifest mild motor deficits in one or both lower extremities, inversion of the foot, inability to land on the heel when walking, followed by involuntary twisting movements of the trunk and extremities, leading to severe functional impairment. The twisting or spiral movement of the whole body is the characteristic manifestation of this disease. Patients with twisting spasms admitted to neurosurgery have both severe and mild symptoms, ranging from self-care in mild cases to bedridden in severe cases. Myotonia increases during twisting movements and returns to normal when calm. This is the name given to deformational dystonia. Torsional spasm is aggravated by nervousness and disappears when sleeping, muscle strength and depth of sensation are normal, intelligence is normal or reduced, the course of the disease progresses rapidly or slowly, some cases can be long-term pause without aggravation. [Internal medicine treatment] The drugs usually tried for torsional spasms are sedatives, muscle relaxants and drugs for Parkinson’s disease. Patients with dystonia starting in childhood should usually be given a small amount of dopa preparations prior to surgical treatment. Alternative medications include the anticholinergic drug benzhexol hydrochloride (Antan). Benzodiazepine preparations such as clonazepam, nitrazepam, baclofen, carbamazepine, haloperidol, and butalbitalazine are not very effective in treatment, and some drugs have significant side effects with long-term use. High doses of benzhexol can cause dry mouth, blurry eyes, memory loss, and urinary retention. High doses of baclofen can produce confusion, hallucinations, noisy sleep, and weakness. Torsional spasms are generally not easily treated. There is no definite effective pharmacological treatment. If the symptoms are obvious and affect work and life, surgical treatment is performed. 【Surgical treatment】 For patients with severe torsion spasms for whom drug treatment is ineffective, brain pacemaker implantation can be chosen to treat torsion spasms. DBS can effectively relieve dystonia and improve the symptoms of patients with torsion spasms. Moreover, DBS has the advantages of reversibility and modifiability without permanent damage to tissues, and is especially suitable for pediatric patients whose brain development is not yet complete. The stimulation targets include Vim nucleus, Gpi, STN, Vop, etc. The stimulation frequency is about 130-180Hz, and the procedure can be performed unilaterally or with bilateral simultaneous implantation of electrodes for stimulation. Patients with torsional spasm treated with brain pacemakers have all obtained significant relief of symptoms after surgery, normalized limb posture, and improved quality of life
