Abstract

La présente invention concerne un outil d'application de pression pneumatique (E1) comprenant : un corps (1a) cylindrique à envelopper autour d'un membre inférieur et d'un pied ; et une pièce d'expansion (2) qui est montée sur une partie côté interne du corps (1a) correspondant à une plante d'un pied. Le corps (1a) présente une paroi périphérique qui est formée en une structure type sac étanche à l'air. Le corps (1a) présente un premier orifice d'alimentation/d'évacuation d'air (14) pour alimenter de l'air dans l'intérieur de la paroi périphérique type sac. La pièce d'expansion (2) est formée en une structure type sac étanche à l'air et présente un second orifice d'alimentation/d'évacuation d'air (21) pour alimenter l'air dans l'intérieur de la pièce d'expansion (2). Lorsque l'air est alimenté depuis le premier orifice d'alimentation/d'évacuation d'air (14), le corps (1a) est gonflé de façon à exercer une pression sur le membre inférieur et le pied. Lorsque l'air est alimenté depuis le second orifice d'alimentation/d'évacuation d'air (21), la pièce d'expansion (2) est gonflée afin d'amener l'articulation de la cheville à s'étendre, produisant ainsi l'étirement d'un muscle fléchisseur au niveau de l'articulation de la cheville.
