Ultrasound refers to mechanical vibrations which are essentially the same as sound waves but of a higher frequency. Such waves are beyond the range of human hearing and can therefore be called ultrasonic


Difference between longwave and shortwave ultrasound


Longwave: lower frequency – around 40KHz = 40.000 pulses/sec., less scattering, greater depth of penetration, no cavitation.

Shortwave: higher frequency ranging between 800KHz to 3MHz, greater scattering, less depth of penetration, has potential to cause unstable cavitation

Your Veterinary Physiotherapist has been trained to understand the exact frequency required for each specific condition

The physiological effects of ultrasound are almost identical to those of Pulsed Shortwave and Laser therapy – the key difference however, is that ultrasound energy is preferentially absorbed in different tissue to the other modalities 


Use of Ultrasound in veterinary physiotherapy:

  • Fracture repair

  • Tissue healing

  • Trigger point

  • Osteoarthritis

  • Haematoma– after 72 hours from injury

  • Chronic wounds

  • Tendon and ligaments damage

  • Fibrotic myopathy

  • Sacroiliac strain

  • Muscle tears

  • Scar tissue

  • Tenosynovitis

Treated conditions:

  • Post-operative treatment

  • Superficial tissue bruising and heamatomas

  • Soft tissue problems: muscle, tendon, fascia and ligaments

  • Mastitis

  • Wounds (acute, chronic)

  • Gingivitis in cats

  • Otitis

  • Acute injuries

  • Chronic skin problems
