Computational Method to Verify Static Alignment of Transtibial Prosthesis
Authors: , ,
Abstract: In Colombia, amputations are not only due to cardiovascular or traumatic causes. According to the Presidential Program for Action against Antipersonnel Mines, amputations inflicted by this type of mines increased between 1990 and 2020 due to the predominance of the armed conflict (mainly in the lower members). The most used method for the amputee is the prosthesis, however, the prosthetic adaptation requires processes and procedures that go according to each individual, existing one generalized, the alignment of the prosthesis. Alignment is the key element of an optimal prosthetic function. The relationship between the prosthesis, the patient, and the components of the prosthesis, critically affects the functional performance and comfort. A new static alignment method for transtibial prostheses is suggested using computational models. An application was made in MATLAB® environment, making use of Neural Networks of Generalized Regression (GRNN), which allows predicting biomechanical data from the alignment of the prosthesis socket. A graphical user interface was developed to show the functioning of the algorithm, this was validated with recorded data of amputees, which allowed to evaluate the repeatability and accuracy of the results obtained. This application seeks to build a support system for the prosthetics technician to improve the rehabilitation process of a person using transtibial prosthesis.
