myotonia Path.|maɪəˈtəʊnɪə|
[mod.L., f. myo- + Gr. τόν-ος tone n. + -ia1.]
1. The inability to relax voluntary muscle for a period following its use; any condition characterized by this.
1898Jrnl. Nerv. & Mental Dis. XXV. 509, I think it proper to assign all such cases to the one clinical category of myotonia. Ibid. 510 Cases which show symptoms of organic disease..can at once be excluded from the group of myotonias. 1905Ibid. XXIX. 416 Myotonia appears to have been used also in the collective sense. Hochsinger describes as myotonia of infancy the persistent hypertonicity of the flexors, and diagnosticates it from tetany, but if myotonia is used as an inclusive term it is a question if it should not cover tetany itself, while if it is used in the narrow sense it has been preëmpted by Thomsen's disease. 1948F. B. Carlsen tr. Thomasen's Myotonia ii. 15 There is a definite difference in the ages at which the myotonia in Thomsen's disease..on the one hand, and dystrophia myotonica on the other, manifests itself. 1963Caughey & Myrianthopoulos Dystrophia Myotonica p. x, Her father was a London professional man who had myotonia of the grip. 1970Masters & Johnson Human Sexual Inadequacy viii. 220 Specific evidence has been accumulated of the incidence of both myotonia and vasocongestion in the female's pelvis as she responds physiologically to sex-tension elevation.
2. In the (usu. mod.L) names of specific diseases in which myotonia is a prominent feature, as:
a. myotonia congenita [A. Strümpell 1881, in Berliner klin. Wochenschr. 28 Feb. 121/2], congenital myotonia (rare), a rare hereditary disease manifested soon after birth and characterized by myotonia but without muscular wasting or other symptoms. Also called Thomsen's disease.
1886Brain IX. 113 The eighth article..makes confusion worse confounded by using another term, viz. dysmyotonie congénitale, almost adopting Strumpell's term, congenital myotonia. 1887Jrnl. Nerv. & Mental Dis. XIV. 129 (heading) Thomsen's disease (myotonia congenita). 1963Caughey & Myrianthopoulos Dystrophia Myotonica xviii. 216 Myotonia congenita..was described in detail in 1876 by Dr. Asmus Julius Thomsen who was himself affected and in whose family it had occurred for five generations. 1974J. T. Hughes Path. Muscle iv. 76 In contrast to myotonia congenita and paramyotonia congenita, dystrophia myotonica is frequently diagnosed.
b. myotonia atrophica [tr. F. myotonie atrophique (G. Rossolimo 1902, in Nouvelle Iconographie de la Salpêtrière XV. 63)], a hereditary condition characterized esp. by myotonia, muscular wasting, cataracts, frontal baldness, and gonadal atrophy. Also called dystrophia myotonica.
1908Jrnl. Nerv. & Mental Dis. XXXV. 269 Myotonia atrophica is an extremely rare affection. 1963Caughey & Myrianthopoulos Dystrophia Myotonica p. viii, Dystrophia myotonica has been known as myotonia atrophica, Steinert's disease, dystrophia myotonica or myotonic dystrophy. 1974J. N. Walton Disorders Voluntary Muscle (ed. 3) xv. 595 Dystrophia myotonica (myotonia atrophica) was described by Steinert (1909) and Batten and Gibb (1909). |
