Abstract
The orthosis comprises a leg portion and a foot portion. The leg portion which extends upwards from the ankle serves to apply therapeutic compression to the leg once the orthosis has been put on. The foot portion which extends from the malleolar region to the toes and covers the instep is a shaped portion that envelops the foot elastically. The dimensioning and the mesh structure of the foot portion are such that 0<Px<Pm<Pb once the orthosis has been put on, Px being the pressure applied to the instep region, Pm being the pressure applied to the malleolar region, and Pb being the therapeutic compression applied to the ankle region. Preferably, Px=5 mmHg±25% and Pm=0.5(Pb+Px)±25%.
