Abstract
A lower leg assembly includes laceration indicators at a knee joint and at a front of a tibia. The tibia is connected to a thigh of a dummy by a pivot arm and a potentiometer is provided for measuring relative motion between the tibia and the pivot arm. A damper is positioned between the tibia and the pivot arm. A load cell is connected between the tibia and a lower leg to ankle connector. The connector is pivotally connected to an ankle joint and the ankle joint has a ball which cooperates with a socket formed in a foot assembly to simulate the range of motion of a human foot-ankle joint. Cushions are provided at the connector to ankle joint connection and the ball to socket connection to return the ankle and foot to a neutral position.
