“…By doing so could potentially broaden, deepen and potentially strengthen prosthetic limb design and its subsequent performance. For example, the inclusion of the athletes favourite colour on their prosthetic limb design has drawn positive feedback from an athlete (Yamanaka et al 2011) and the use of painted striping improved the paddling biomechanics of a rower by manipulating the athletes visual perceptions (Millar and Oldham 2016). This suggests that form aspects can interact directly with functional outcomes so whilst both are focused on separately, they should not be completely ring-fenced from each other.…”

Sport with a disability has progressed from undertaking physical activity for recreation to one of a high performance environment at competitions such as the Paralympic Games. There is currently limited information and guidance to help inform stakeholders as to how to develop the high performance technology of elite athletes who possess limb absence. In this manuscript, a conceptual framework for high performance prosthetic limb creation is presented. This utilises a synthesis between contemporary product design theory and a review of existing case studies. This proposed framework is then applied to a case study. Ultimately, the framework provides an indicative guide to the creation of prosthetic limbs that emphasise technological performance enhancement over that of mere sporting participation.

“…When the legs are design for sports purpose, they have to withstand extremely high level of loadings in a very fast pace. Therefore, they are often structured as one flexible body and non-powered as shown in Figure 1a (Yamanaka et al [1]). For a walking purpose, it is more flexible in design due to low speed and loading conditions.…”

Current knee designs for prosthetic legs rely on electric motors for both moving and stationary states. The electric motors draw an especially high level of current to sustain a fixed position. The advantage of using magnetorheological (MR) fluid is that it requires less current and can have a variable braking torque. Besides, the proposed prosthetic leg is actuated by NiTinol wire, a popular shape memory alloy (SMA). The incorporation of NiTinol gives the leg more realistic weight distribution with appropriate arrangement of the batteries and wires.The prosthesis in this research was designed with MR brake as stopping component and SMA wire network as actuating component at the knee. The MR brake was designed with novel non-circular shape for the rotor that improved the braking torque while minimizing the power consumption. The design also helped simplify the control of braking process. The SMA wire network was design so that the knee motion was actively rotated in both directions. The SMA wires were arranged and played very similar role as the leg's muscles. The study started with the overall solid design of the knee including both MR and SMA parts. Theoretical models were derived and programmed in Simulink for both components. The simulation was capable of predicting the power required for moving the leg or hold it in a fixed position for a certain amount of time. Subsequently, the design was prototyped and tested to validate the theoretical prediction. The theoretical models were updated accordingly to correlate with the experimental data.
