The most common of the focal dystonias, torticollis is a state of excessive of inadequate muscle tone in the muscles in the neck that control the position of the head. It can cause the head to twist and turn to one side, and the head may also be pulled forward or backward. Torticollis can occur at any age, although most individuals first experience symptoms in middle age. It often begins slowly, and usually reaches a plateau. About 10 to 20 percent of those with torticollis experience a spontaneous remission, but unfortunately the remission may not be longlasting. Also known as spasmodic torticollis.

tor·ti·col·lis .tȯrt-ə-'käl-əs n a twisting of the neck to one side that results in abnormal carriage of the head and is usu. caused by muscle spasms called also wryneck

* * *

an irresistible turning movement of the head that becomes more persistent, so that eventually the head is held continually to one side. This is a form of dystonia. The spasm of the muscles is often painful and the patient is sensitive about his appearance. It may be caused by a birth injury to the sternomastoid muscle (see sternomastoid tumour). Relief may be obtained by cutting the motor nerve roots of the spinal nerves in the neck region or by injection of the affected muscles with botulinum toxin.
