Orthopädischer trainingssimulator mit haptischem feedback

Various clinical evaluation tests exist for the diagnosis of joint injuries. However, training of these tests on real patients is cumbersome as well as time and cost-consuming. In this paper a multi-modal environment is proposed that supports the training of clinical joint evaluation of the knee joint. A combined display with haptic, visual, and auditory feedback allows a user to touch and move the shank of a virtual patient, while observing the internal joint anatomy and listening to sounds produced by the joint or uttered by the patient due to pain. Various closed-loop control architectures are presented that enable a haptic interaction between the user and the shank. First promissing results from a simple biomechanical knee model, integrated in an admittance control architecture, are presented. The future use of the training environment in the field of medical education is discussed.
