[Study of the pathogenesis of tremor in parkinsonism by the technic of spectral analysis of the rounded EMG using a computer]

Abstract

Tremor was studied in 2 forms of parkinsonism. A new method of computerized spectral EMG analysis was employed in the investigation. Amplitude and frequency characteristics of tremor in parkinsonism have been identified, which make it possible to objectify the diagnosis at the early stages of the disease and to facilitate its differentiation from other types of pathological tremor. The developed method may be used for assessing the efficiency of the chemotherapeutical and surgical treatment of parkinsonism. Some suggestions were made concerning the mechanism of pathological tremor.
