Abstract/OtherAbstract:
|
The study tried to reveal the differences between physiological and pathological tremor appearing during maintenance of isometric force in healthy individual and parkinsonian patients with tremor. Six-level wavelet expansion was used presenting the tremor as a sum of smoothed (slow) component and high-frequency detailed components of 6 expansion levels. The differences in the high-frequency components were assessed by calculating the energetic parameters in the power spectrum of these components. These parameters make it possible not only to reliably distinguish the energetic spectra of the detail components of the physiological and pathological tremor, but also to correlate changes in patient state caused by drug treatment of parkinsonian trembling with the decrease in these parameters. |
