Abnormality of extrapyramidal motor function	A neurological condition related to lesions of the basal ganglia leading to typical abnormalities including akinesia (inability to initiate changes in activity and perform volitional movements rapidly and easily), muscular rigidity (continuous contraction of muscles with constant resistance to passive movement), chorea (widespread arrhythmic movements of a forcible, rapid, jerky, and restless nature), athetosis (inability to sustain the muscles of the fingers, toes, or other group of muscles in a fixed position), and akathisia (inability to remain motionless).   Synonyms:Extrapyramidal dysfunction; Extrapyramidal signs; Extrapyramidal symptoms; Extrapyramidal syndrome; Extrapyramidal tract signs	Very frequent
