Spasmodic cervical tilt is a disease in which the muscles of the neck experience spasms and clonus that cannot be controlled autonomously, mainly manifested as spasmodic tilting and twisting of the head and neck without control, and may be accompanied by spasmodic pain in the muscles. The exact cause of this disease is not clear, and it may be related to central nervous system injury, mental stress, vascular malformation or compression, heredity and so on. At present, spasticity tilt is not curable, a small number of patients may be relieved on their own but will recur. The disease can be treated with optional botulinum toxin injections, including botulinum toxin type A or B, which can serve to block neuromuscular signaling, thus reducing the spasticity of the neck. Botulinum toxin is contraindicated in people who are allergic to the ingredients, myasthenia gravis, or infected at the injection site; and adverse reactions such as local pain, abnormal sensation, swelling, infection, bleeding, or drooping eyelids, ecchymosis of the skin, headache, nausea, and muscle weakness may occur after the administration of the drug. Drugs need to be rationally applied under the guidance of a physician.
