Abstract

The invention concerns a method which consists in producing a radiographic image of the skeleton to be studied, determining the position of the body's global axis of gravity (5), selecting on the image segments of the skeleton (S1-S7) to be considered and their articulations (A5), locating the main tensor muscles (M1-M6, M62), and determining by calculation the intensity of the return forces exerted by said tensor muscles to compensate the gravitational force.
