The High-frequency soundproof Pressure Waves. O.P.A.F.® THERAPY Veterinary introduces a new method that, by exploiting modulated frequencies and varying emission, provides high power energies to tissues at diﬀerent depths. The operator can now use an equipment that is safe, eﬀective, highly tolerated by animals and usable for multiple pathologies. Moreover, since the device works silently, the treatment can be carried out in a comfortable way and without scaring the animal. The therapy is performed with the animal in place without sedation.
