A system (10) for detecting and displaying baropostural parameters comprises a platform (11) with a footplate (15) intended to accommodate a person standing on it and provided with sensors for detecting the pressure distribution of the imprint of the two feet on the footplate. An electronic acquisition device (32) is connected to the sensors for digital acquisition of the pressure distribution in order to create a map of the pressure points of the feet on the footplate. Calculation means (33a) are designed to calculate, for each foot and for both feet on the footplate, the geometric centres (52, 53, 54) and the barycentres (55, 56, 57) of the map of the pressures and display means (33b) display on a screen (31) a graphical representation of the imprints of the two feet on the footplate together with the corresponding geometric centres (52, 53, 54) and barycentres (55, 56, 57) calculated by the calculation means. The footplate may have a rear part (15) which can be raised for simulating shoe heels underneath the heels. Front and/or lateral telecameras (19, 20) may be provided in order to provide further postural data.
