[The spectral analysis of the variability of frequency and amplitude characteristics of tremor in patients with essential tremor and tremulous form of Parkinson's disease].
A clinical and electrophysiological analysis of tremor in patients with essential tremor and tremulous form of Parkinson's disease as well as healthy subjects has been conducted. The method of accelerometry was used for assessing the variability of frequency and amplitude tremor. A comparison of the time-domain characteristics and spectral components of tremor was made between the two groups of patients that allowed to find the series of typical characteristics, which were important for understanding of its pathogenesis and differential diagnosis of this disease.
