Claim 0:
1. A method for the design of therapeutic insoles comprising:
providing a plurality of medical criteria about biomechanics of a lower extremity of a body and a plurality of therapeutic insole design criteria, which parameters are previously determined in an arbitrary manner;
providing a database with shape data information, which includes a shape and characteristics of shoe trademarks and models;
determining an individual-specific input by an exam and/or clinical interview based on the existence of concomitant pathologies and conditions, indicators of physical activities, posture observation, anatomical dimensions and foot anthropometry
using a first device to measure a dynamic and/or static plantar pressure of the foot;
determining, by the first device, a set of plantar pressure data, for the measurement of foot function and gait analysis, during a determined interval of time;
using a second device to measure the alignment of bone segments of the lower extremity of the body;
determining, by the second device, a set of image data for the measurement of bone segments alignment of the lower extremity of the body and the relation between them;
wherein further including the following steps:
providing an algorithm-driven design to carry out the design of a plurality of three-dimensional elements, by determining at least the following:
a) a set of implementation instruments, which contains the mathematical and programming implementation of all the recommendations and medical criteria that were compiled in the systematic review and internal studies;
b) an individual characterization, which contain the diseases, pathologies, physical activities, and all the medical-related analysis, based on the individual-specific input obtained previously;
c) a set of plantar characterizations of the individual, which contain a footprint analysis and gait analysis, based on the data obtained by the first device;
d) a set of alignment characterizations of the individual bone-alignment, which contain a representation and inclination analysis, based on the data obtained by the second device;
e) a set of shapes are determined from the inner shape data and the plurality of characterizations, which are weighted individually or correlated;
f) a diversity of geometric parameters from the previously mentioned shapes, which value types include angles, lengths and percentages;
using said algorithm-driven design to determine the plurality of three-dimensional elements;
wherein the location and geometry of each three-dimensional element are calculated based on the mentioned shapes and parameters, and the correlation between them, where each of the three-dimensional element pursues one or more specific objectives, for the redistribution of anomalous pressure and/or alignment of bone segments;
conforming a 3D model based on the combination of at least two of the plurality of three-dimensional elements;
wherein the footprint analysis infers the geometry of a number of zones and quantities along the foot, based on the peak and mean pressure values, as measured in a dynamic pressure examination, through contour levels;
wherein the gait analysis is measured through at least three dynamic samples of each foot, and the standing of the individual; and
wherein the set of obtained results with the footprint analysis and gait analysis, of all the plantar pressure data of the individual, are then individually weighted for the construction of the shapes.
