Popis: We investigated in patients with chronic venous insufficiency (CVI) and after compression therapy the fluxmotion within characteristic frequency bands, which were described earlier by Bracic and Stefanovska (Bull. Math. Biol. 60 (1998), 919-935).Therefore, the frequency spectra of laser Doppler flux data of the 36 patient's legs were compared with 41 legs of healthy subjects. In addition, 14 patients with CVI wore a compression stocking (interface pressure: 25-32 mmHg) or compression bandages and were measured after 4 weeks therapy. Data were analyzed by means of a Wavelet packet transformation (a combination of the Daubechies filter of order 4 and the Haar filter).We found significant differences between the patients and the healthy subjects in the frequency intervals of myogenic 0.06-0.16 Hz, respiratory 0.16-0.6 Hz and heart activity 0.6-1.6 Hz (p
