A computerized prosthesis alignment system includes a transducer that can measure socket reactions in the anteriorposterior plane and the rightleft planes, while canceling or reducing the transverse forces on the measurements of these socket reactions. One or more exhibited symptoms may be obtained for a patient. An opening is defined in the bottom plate. Further, a manual which correlates each of the shapes with the number of unobstructed counting apertures that are visible when each shape is formed correctly may be provided together with the pivotally manipulable toy.
