Original abstract
Standardized patterns of examination were developed in order to differentiate the disorders of the extrapyramidal system by means of electromyography. Pathological muscle activity was registered by stationary electromyography during rest, maintained posture, directed movements and passive extremity-excursions. Telemetric electromyography using eight-channel-biotelemetry-equipment showed pathological patterns of innervation in movements which are connected with migration such as walking. Characteristic findings were acquired in parkinsonism, choreatic, torsion dystonic and athetotic syndromes, ballism, Wilson's disease and drug induced dyskinesia as well as other hyperkinetic syndromes. The electromyographic findings proved to be useful in objectifying and differentiating the insufficient clinical data.
