Encyclopedia entry (1928–1936)
AMYOTAXIA [from the Greek a - negative particle, mys (myo)-muscle and taxis-order], a term proposed by Rossolimo in 1893 for violent, choreo-athetoid twitchings in diseases of the spinal cord and peripheral nerves (spinal form - amyotaxia spinalis) and in 1894 - for the cerebral form of A. (amyotaxia cerebralis) with similar complex, violent, also choreo-athetoid hyperkinesias, based on constitution, obsessive states, and in combination with stuttering, writing spasm, and obsessive ideas from the psyche. In terms of its pathophysiological essence, the phenomena of A. should be reduced to disorders of muscle tone regulation, localized, in the cerebral degenerative form, in the striopallidal system.
