| progressive torsion spasm | 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) |

| spermatic cord torsion | Torsion of the spermatic cord caused usually by incomplete attachment of the epididymis to the testis or by inclusion of the cord within the tunica vaginalis. Faulty development of various anatomical components of the testes is also a cause. It occurs most frequently in childhood and adolescence. (12 Dec 1998) |
| dystonia, idiopathic torsion | A form of dystonia known as early-onset torsion dystonia (also called generalised torsion dystonia) 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. (12 Dec 1998) |
| dystonia, torsion | A form of dystonia known as early-onset torsion dystonia (also called idiopathic or generalised torsion dystonia) 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.

| intravaginal torsion | Torsion below insertion of tunica vaginalis. See: bell clapper deformity. (05 Mar 2000) |
| testicular torsion | <surgery> An acute condition that results when there is a twisting of the spermatic cord in the scrotum, thus compromising the blood supply to that testicle. Symptoms include severe testicular pain and swelling. (13 Jan 1998) |
| torsion | 1. <surgery> A type of mechanical stress, whereby the external forces (load) twist an object about its axis. 2. <ophthalmology> Any rotation of the vertical corneal meridians. Origin: L. Torsio, torquere = to twist (18 Nov 1997) |

| 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) |

| torsion spasm | <clinical sign, neurology> Disordered tonicity of muscle. Origin: Gr. Tonos (18 Nov 1997) |
| torsion testis | A group of structures which go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves. (12 Dec 1998) |
