Each year, over 5400 UK patients are referred to lower limb prosthesis clinics (2011), of whom over 90% are below- or above-knee amputees. The main causes of amputation are diabetes, limb dysvascularity (loss of blood supply), accidents and injury in the battlefield. Prosthetic legs have the potential to dramatically improve the mobility, confidence and the quality of life of users. With an effective prosthetic solution, users can be independent in their daily living, e.g. walking, stair climbing and potentially running. In addition, advanced prosthetic legs enable amputees to improve their posture which in turn has a positive effect on reducing wear-and tear on their unaffected joints. However, individuals with lower-limb amputation lack the nervous structures associated with the foot and ankle from the prosthesis and, compared with able-bodied individuals, suffer from lack of stability. Technologies do not exist for targeted delivery of feedback information from the prosthesis to the nervous system. As part of the EPSRC-funded SenseBack project, a highly-experienced team of UK researchers are developing a number of key technologies to restore sensation to the individuals using prosthetic hands. The proposed translational Alliance between Newcastle University and Össur (www.ossur.com) will facilitate translation of the the technologies developed in the SenseBack project to lower-limb prostheses. With Össur, within the next decade, we aim to create an artificial leg that can generate mechanical power, adapt autonomously to the user's changing needs and also provide feedback to the user regarding the state of the limb and the prosthesis.
