Abstract: An extremity dummy includes a first and a second dummy section which are connected in an articulated manner by a joint element having at least one axis of rotation and also includes a sensor by which the angular position or angular change of the connected dummy sections with respect to the axis of rotation to which the sensor is provided can be measured. Preferably, a respective sensor is provided to each of the axes of rotation of the joint element. A method for testing an orthosis using the extremity dummy is also provided.
