Medical compression stockings (MCS), abreviated here after as MCS, are designed to exert therapeutic pressure on the leg aiming at treating venous deseases or lymphatic disorders. One one hand, the MCS are categorized by their class of compression defined by the norms (in our study we refer to the GZG RAL 387); on the other hand, we also need to consider the true pressure exerted by a given MCS on a given leg, this true (“in-situ”) pressure can be evaluated by a sensor placed between the leg and the MCS (presently, the instrument in use for in-situ measurements is the SIGaT). Quite frequently, the figures issued from in-situ measurements do not perfectly correspond to the values measured according to the norms. In this paper, we explain how the normative pressure is measured on the Hosy machine according to the german norms and how to compare those figures to the in-situ (or simply “on-leg”) pressure evaluated with the SIGaT instrument.
