| torsion disease of childhood | A genetic, environmental, or idiopathic disorder, usually beginning in childhood or adolescence, marked by muscular contractions that distort the spine, limbs, hips, and sometimes the cranial-innervated muscles. The abnormal movements are increased by excitement and, at least initially, abolished by sleep. The musculature is hypertonic when in action, hypotonic when at rest. Hereditary forms usually begin with involuntary posturing of the foot or hand (autosomal recessive form ) or of the neck or trunk (autosomal dominant form ); both forms may progress to produce contortions of the entire body. Synonym: progressive torsion spasm, torsion disease of childhood, torsion dystonia, Ziehen-Oppenheim disease. (05 Mar 2000) |
| torsion dystonia | A form of dystonia known as early-onset torsion dystonia (also called idiopathic or generalised torsion dystonia) that begins in childhood around the age of 12. Symptoms typically start in one part of the body, usually in an arm or leg, and eventually spread to the rest of the body within about 5 years. Early-onset torsion dystonia is not fatal, but it can be severely debilitating. most children with the disorder are unable to perform the simplest of motor tasks and are confined to a wheelchair by the time they reach adulthood.

| torsion neurosis | An affection characterised by lordoscoliosis of the lower portion of the vertebral column, occurring when the patient stands or walks and usually disappearing when the patient lies down. Synonym: torsion neurosis. (05 Mar 2000) |
