An artificial limb (e.g., leg) is provided with rigid members simulating the lower and upper halves of the lower leg, the knee joint and the upper leg. At each joint is a sensor-potentiometer similar to the joy-stick of a computer game arranged so that relative movement of rigid members cause movement of the joy-stick. Leads from the outputs of the sensors are connected to an analog-to-digital converter connected to a personal computer. In teaching first aid for fractured limbs, the student is taught to apply splints and move the patient to a stretcher with as little relative movement as possible. The training device indicates relative movement. The screen may display positions of the rigid members in two planes and/or numerical tallies.
