Impact of Prosthesis Fit on Nutritional Health of the Lower Limb Amputee

Abstract

Socket designs ensure optimum fit between the user and the device (prosthesis), as an interface between the human – machine system. The type that an amputee is “fit with” depends on the shape of the residual limb, the length of the residual limb, activity level, prognosis, and individual preference. Patient satisfaction and function relies on pressure and force distribution (Biomechanics) on the socket-residual limb interface. The most determinant factor of prosthetic use lies in the design of the prosthetic socket and fit depends on the degree to which the prosthesis fits the stump. Well planned socket designs and careful consideration of stump presentation had set an achievement platform for the prosthetic user by maximizing range of motion, stability during the performance of daily activities, and comfortably distributing the forces exerted on the residual limb during movement and suspension. A study was conducted to analyze the health issues and their impact on the use/ acceptance of prosthesis among select amputees’. Physiological factors, obesity, age, nutritional status and co-morbidities were found to impose mechanical implications related to accessibility and well being concepts. The study highlighted prosthetic fitting to be more challenging with increased load (obesity) to transmit through the prosthetic socket in limited pressure–tolerant anatomical areas. Hence nutritional and physiotherapy intervention on effective and efficient prosthetic use was done to enhance their health and well -being.
