A prosthesis or orthosis (orthotic brace) includes at least two parts connected to each other by an artificial joint and a control device to brake or lock the joint. The prosthesis or orthosis includes a sensor which detects the position in relation to a fixed line of a part connected to the joint and which is connected to a control device arranged to influence the joint on the basis of position data given by the sensor. The prosthesis or orthosis is a lower limb prosthesis, such as a thigh prosthesis or a hip ex-articulation prosthesis, or a lower limb orthosis. The sensor is arranged to detect the position of the thigh part in relation to a vertical line. The control device is arranged to influence the movement resistance properties of the joint on the basis of data given by the sensor. The sensor is based on detecting the direction of earth's gravity. |
