The traditional PTB socket with PE-lite has been used for a long time in the developing countries. Many studies suggest improving the prosthetic comfort through the use of roll-on liners. There are many varieties of liner, however, these liners are expensive and difficult to obtain for persons residing in RLE. The aim of this study was to determine the feasibility of the Roll-on liner made from the affordable EVA material (AERO). Five transtibial amputees were invited as the participants in order to evaluate the utility of the AERO liner. The outcomes with respect to pressure distribution, daily step count, questionnaire, and material test were explored. There were no significant difference between daily activities and questionnaires, and the mean pressure uniformity across all five participants showed that the uniformity with the PTB socket with PE-lite was 35.38% (?10.81), PTB socket with AERO liner was 56.77% (?6.73), and TSB socket with AERO liner was 77.53% (?5.44). Thus, the pressure uniformity across the residuum was improved when using the AERO liner, in both PTB and TSB style sockets. Moreover, the AERO liner can be made cheaper than the conventional PE-lite. This low-cost Roll-on liner may contribute to sustainable development in limited resource environments. For future studies, perspiration problems in daily living, and the appropriate socket shape and suspension systems can be considered to enhance the comfort for the transtibial prosthesis wearers in the developing countriesxii, 78 leaves : ill.application/pdfengผลงานนี้เป็นลิขสิทธิ์ของมหาวิทยาลัยมหิดล ขอสงวนไว้สำหรับเพื่อการศึกษาเท่านั้น ต้องอ้างอิงแหล่งที่มา ห้ามดัดแปลงเนื้อหา และห้ามนำไปใช้เพื่อการค้าProsthesis -- Technological innovationsOrthopedic apparatusMaster ThesisMahidol University
