Spastic torticollis

Spastic torticollis is an extrapyramidal organic disease characterized by cervical muscle torsion or clonic tilt. The clinical manifestations are slow onset, the head does not rotate to one side at will, and the neck bends to the other side, which can be aggravated by emotional excitement. The condition varies from mild or occasional attack to difficult treatment. The disease can last a lifetime and can lead to restrictive movement disorders and postural deformities. The course of disease usually progresses slowly and stagnates after 1 ~ 5 years. Some patients can recover spontaneously within 5 years after onset, usually young and mild. The incidence rate is gender related and age related. The incidence rate of women is usually 1.5 to 1.9 times that of men. The peak age of onset is 50 ~ 60 years old.
