myotonic dystrophy a rare, slowly progressive, hereditary disease, marked by myotonia followed by muscular atrophy (especially of the face and neck), cataracts, hypogonadism, frontal balding, and cardiac disorders. Called also dystrophia myotonica, myotonia atrophica, and myotonia dystrophica.
progressive muscular dystrophy muscular dystrophy.
pseudohypertrophic muscular dystrophy muscular dystrophy affecting the shoulder and pelvic girdles, beginning in childhood and marked by increasing weakness, pseudohypertrophy of the muscles, followed by atrophy, and a peculiar swaying gait with the legs kept wide apart. Called also pseudohypertrophic muscular paralysis.
reflex sympathetic dystrophy a syndrome of chronic pain that usually develops after a trauma or noxious stimulus, although the nerve injury cannot be immediately identified. The pain is not limited to the distribution of a single nerve and is often out of proportion to the precipitating event. It is most often described as a burning pain, and is accompanied by swelling, sweating, sensitivity to touch, and sometimes changes in tissue growth. Called also chronic or complex regional pain syndrome.

Becker's muscular dystrophy

Etymology: Peter E. Becker, German geneticist, b. 1908
a chronic degenerative disease of the muscles, characterized by progressive weakness. It occurs in childhood between 8 and 20 years of age. It occurs less frequently, progresses more slowly, and has a better prognosis than the more common pseudohypertrophic form of muscular dystrophy. The pathophysiological characteristics of the disease are not understood; it is transmitted genetically as an autosomal-recessive trait. Also called benign pseudohypertrophic muscular dystrophy. Compare Duchenne's muscular dystrophy.
