| Summary: | <p>This paper presents the first theoretical and practical work on compression therapy using the Laplace law to estimate pressures under the bandages. Three articles are considered: the first with the warp highly-twisted on cotton, the second with the warp on polyamide and the third with spandex wrapped by cotton yarn. Starting from these woven fabrics, three models, E<sub>5</sub>, E<sub>6</sub> and Ef have been developed with respective elongations of 108 %, 86 % and 92 % and specific mechanical behavior. The results show that than the single layer bandages develop much higher pressure than the multilayer bandages but the multilayer bandages exert much more uniform pressure than single layered bandages. Obtaining uniform pressure along the length of the leg is a positive result in this treatment. Averages circumferences of the human body are used for the pressure calculations in four zones: C<sub>1</sub>, C<sub>2</sub>, C<sub>3</sub> and C<sub>4</sub>.</p>
