This paper presents a stage in the research on the development and implementation of a low cost, flexible, and efficient method for assisted testing of foot prostheses, as the case. This paper describes a method for assisted evaluation of three types of foot prostheses standpoint form deviation (hip prosthesis and two osteosynthesis plates for fibula and tibia).The key aspect of the developed method is a software application as virtual instrument programmed in this research stage. Its role is to provide as quickly and objectively as possible all necessary information on the results of testing. The main advantage of the created and applied virtual instrument is that it is flexible and user friendly, so that it can be successfully used in all orthopedic surgeries. This research stage (described) includes the software application programming and also its application to process all measured data in terms of form deviation for all three tested foot implants.

In this paper, a stage of a research activity in the orthopedic field for testing modern materials composing foot insoles at different tasks, such as simulating walking, running, orthostatic position, or sitting, is described. This stage concerns the testing of five samples of materials taken from five patterns of inlets, subject to a degradation process, over different time periods. The degradation process consists of subjecting the immersed samples to a 15-20% saline solution at static loads of about 400 N. The salinity percentage is established so that the solution obtained is similar to that of sweat, which occurs especially in the warm season while wearing the shoes. The exposure to degradation times is established at 3 and 7 days, respectively. The main aspects are the degree of compaction and the degree of deformation of the samples, as a result of maintaining different times in degradation conditions.
