Purpose: The aim of the study was to evaluate the effects of a 6-week sEMG-biofeedback-assisted pelvic floor muscle training program on pelvic floor muscle activity in young continent women. Methods: Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Biofeedback training was continued for 6 weeks, 3 times a week. Muscle strenghtening and endurance exercises were performed alternately. SEMG (surface electromyography) measurements were recorded on four different occasions: before training started, after the third week of training, after the sixth week of training, and one month after training ended. Results: A 6-week sEMG-biofeedback-assisted pelvic floor muscle training program significantly decreased the resting activity of the pelvic floor muscles in supine lying and standing. The ability to relax the pelvic floor muscles after a sustained 60-second contraction improved significantly after the 6-week training in both positions. SEMG-biofeedback training program did not seem to affect the activity of the pelvic floor muscles or muscle fatigue during voluntary pelvic floor muscle contractions. Conclusions: SEMG-biofeedback-assisted pelvic floor muscle training might be recommended for physiotherapists to improve the effectiveness of their relaxation techniques.

The paper presents the computational approach to the process of creation of complex three-dimensional finite elements models. The data are automatically received by the measuring unit and sent directly to the computer. The process of numerical treatment of measuring points' coordinates is shown. As an example of above mentioned method, the construction of human femoral head model is demonstrated. Finally the geometrical model of the object, which can be used by PATRAN system is obtain. Paper presents results of numerical calculations and compares it with a photoelastic experiment.

Opisano proces modelowania złożonych struktur przestrzennych. Informacja o geometrii tych struktur jest zapisywana w plikach STL i stanowi dane wejściowe opisywanej metody. Jako przykład przedstawiono proces modelowania głowy kości udowej człowieka wraz z matematycznym opisem jej właściwości. Modelowanie wykonano, korzystając z języka PCL i systemu PATRON.

The paper presents the mutation of standard local interpolation of a sequence of points by the Bezier segments. This method is applied in photoelastic experiment, but can be used in any approximation where the data are distributed sparsely. Finally the results of approximation of photoelastic experiment to be as-sessed in FEM calculations have been presented.

W pracy przedstawiono oryginalną przybliżoną technikę zastosowania krzywej Beziera. Metoda ta została zastosowana do analizy eksperymentu fotoelastycznego. Może ona być rów-nież służyć do dowolnego przybliżenia wyników eksperymentu, gdy są one rozmieszczone z dużymi odstępami. Przedstawiono wyniki przybliżenia eksperymentu fotoelastycznego osza-cowane metodą elementów skończonych.
