Method a designing, engineering modeling and manufacturing orthotics and prosthetics integrating algorithm generated predictions

The present invention represents an advancement on the current processes involved in designing, engineering, modeling and manufacturing of orthotic and prosthetic devices. Orthotic and prosthetic computer aided design software has the option to apply measurements to a template to create a patient specific model. The use of algorithm generated predictions (also referred to as “AGP”) software takes this functionality and makes it more scientific. Algorithm generated predictions is the process of predicting the appropriate size and shape data through the use of complex algorithms. Certain key pieces of data are entered into the software that then calculates the appropriate dimensions and the appropriate computer aided design template. The dimensions are then applied to the computer aided design template. The computer aided design software modifies the templates by reducing and enlarging areas as necessary and a custom computer aided design model is created that can then be transformed into a physical model for the manufacture of the device.
