The invention concerns an orthopedic training or therapeutic device for dogs, hoofed animals, and camels that consists of at least one elastic band, at least over part of its length, and that is fastened on one side to the middle rear paw or middle front paw of the extremity being treated and cooperates on the other side with a chest harness of the animal. A pair of laterally-spaced strip portions extend along the dewatering fabric in the machine direction, with each being substantially and consistently impermeable to air and forming a substantially and consistently smooth non-water-retaining surface. The system also includes a module for estimating the power of the audio signal and suitable for providing the automatic gain control module with a current power value for the audio signal. The perimeter may have an airfoil cross-section shape, reducing drag of the frame and aiding in deployment. Thereafter, the difference between the new value input to the static model and the prior steady-state value is utilized as an input to the dynamic model.
