Original abstract
Telemetrical electromyographical investigations were performed in 23 healthy subjects and 33 patients with various diseases of the extrapyramidal system. The comparison of our findings leads to electromyographic criteria in the differential diagnosis of these disorders. As the majority of previous investigations with this method centered on questions concerning functional anatomy, a number of modifications were introduced to apply telemetrical methods to neurological problems. The following pathological findings were elicited by comparison of normal subjects and patients with extrapyramidal diseases: activity of hyperkinesias, coinnervation of antagonists, exceeding activity, altered patterns of single bursts of activity, retarding of activity, changes of the temporal proportions of alternating activity in the tibial muscles while walking. The latter finding was interpreted as sign of disturbed temporal coordination of automatic movement patterns in distinct diseases of the extrapyramidal system.
