Abstract
The objective of this thesis is to illustrate the parameters that define and characterize the elements necessary for an optimal prosthetic socket interface design. Previous studies have revealed that the industry is manufacturing materials that are causing irregularities in gait patterns and causing major discomfort for transtibial amputees. As a result, chances for recovery and rehabilitation of many patients have been greatly reduced.
This study has indicated that the success of a socket liner depends on quantitative and qualitative factors that assess the overall efficacy of an artificial limb. Quantitative analysis is observed through calculations and deviations in gait cycles, and therefore distortions in patterns will determine the overall performance of the prosthesis numerically. The qualitative aspect covers the significance of the residual limb. Based on these two fundamental criteria, it has been concluded that socket interface materials must contain the following characteristics: excellent mechanical properties (to withstand the various impacts and 1oads), flexibility (to adjust to variations in motion), biocompatibility (for prevention of reactions), porosity (to reduce irritations and sores), and functionality (to maintain normality in the amputees gait cycle). Furthermore, additional research was conducted to present and prove polyvinyl chloride (PVC) foam is a material that possesses such requirements.
