<p>An apparatus for the evaluation of the temporal phases, the geometrical data and the reaction forces of the sole of the feet under dynamical conditions. This apparatus essentially provides a walkway (1) formed of three layers (2-4). The upper layer (2) consists of a flexible printed board having conductive paths (5) parallel to one another and applied to the lower face thereof, the middle layer (3) being formed of a conductive rubber sheet able to vary its resistance in the direction of its thickness when pressure is exerted in the direction perpendicular to the faces of the layer, the lower layer (4) being a printed board having conductive paths (6) parallel to one another and applied to the upper face thereof and extending in a direction perpendicular to the conductive paths of the upper layer (3). The apparatus allows the whole walkway to be scanned in real time during the gait of the subject at a sampling frequency higher or equal to 50 Hz, and the distribution of the support pressures exerted by the sole of the feet to be determined in a full gait cycle (double step).</p> |
