<p>The orthosis includes a compressive portion having an ankle portion that, when worn, exerts a nominal textile pressure P0 for an ankle circumference C0. When it is stretched in order to enable it to go past the instep region of the leg, the ankle portion exerts an elastic return force in the circumferential direction corresponding to a nominal putting-on textile pressure P1 for an instep circumference C1. At least one parameter selected from: the natures of the core yarns used for said knit yarn and said weft yarn; any covering of said yarns; and the knitting of said yarns; is selected in such a manner that for C1=1.38C0, said nominal putting-on textile pressure P1 is less than or equal to 120% of said nominal wearing pressure P0. This makes it easier for the patient to put on and take off the orthosis merely as a result of the intrinsic properties thereof and without having recourse to any accessory.</p> |
