Title
Human-centered design of computerized prosthetic leg: A questionnaire survey for user needs assessment
Abstract
© 2019, Springer International Publishing AG, part of Springer Nature. In Thailand, there are approximately 2 million people with disabilities and nearly 50,000 people living with lower limb loss. Previous research investigates the quality of life and factors affecting quality of life of transfemoral and transtibial amputees after receiving prosthesis using a method of WHOQOL – BREF – THAI. However, the WHOQOL – BREF – THAI is a questionnaire that is used to investigate quality of life for normal people not for people living with lower limb loss. Recent records show a lack of satisfaction with the traditional passive prosthetic leg and needs of new active prosthesis with different motor functions. The objective of this research is to design and develop a questionnaire, using human-centered design principles for investigating and improving the quality of life of transfemoral and transtibial amputees after receiving prostheses. The new questionnaire is created based upon both prosthesis evaluation questionnaire (PEQ) and trinity amputation and prosthesis experience scales (TAPES). This questionnaire survey explores user’s satisfaction, usability study, product appearance, comfort and pain, and cleansing and handling the prosthesis. A total of 24 subjects are randomly selected. Data collection and analysis are made from a list of patients in Sirindhorn School of Prosthetics and Orthotics and Veterans General Hospital in Thailand. From the amputees’ point of view, defining their needs is one of the most critical factors in the first step for prosthesis design. Veterans has asked for modern prostheses and they believe that modern prostheses can help them feel more comfortable and natural while performing activities of daily living and improve their quality of life. As a result, this research project provides a list of needs of people living with lower limb loss in Thailand. Findings have indicated that user needs assessment is necessary and critical to make a better computerized lower limb prosthesis design and improve user’s satisfaction.
