An ultrasonic measuring section is used to record posture. At the same time, the ultrasonic transducers (1) are positioned on points on the skin (4) whose mutual spacing changes on movement of the body. Nevertheless, this spacing can be determined by electromagnetic methods. Use of this measuring principle is particularly significant within the framework of a biofeedback method in the treatment of false postures and for measuring the angular position of body joints. <IMAGE>
