Abstract

The development of comfort fit, custom made lower limb prosthesis using the concept of reverse engineering (RE) and rapid prototyping (RP) has been introduced in this paper. The comparison of average percentage of deviations in step lengths also made between normal people, the conventional (plaster of Paris - POP) prosthesis and reverse engineered rapid prototyping prosthesis through gait analysis. The gait analysis reveals that the average percentage of deviation in step lengths in normal person is 2.80, average percentage of deviation in step lengths in conventional (POP) prosthesis is 53.70 and reverse engineered rapid prototyping prosthesis is 7.06. The difference in average percentage of step lengths deviation between normal person and amputed person wearing reverse engineered and rapid prototyping prosthesis is very less (say 4.26) and hence provides comfort fit.
