- ultrasound involves ultra high frequency sound waves.
- Two basic effects thermal and non thermal
- thermal effects are similar to those of heat therapy;increased blood flow,relief of muscle spasms,and increased elasticity of soft tissues in the treated area.
- The primary non thermal effect is the stimulation of cell activity.
- Therapeutic ultrasound improves the rate and quality of tendon repair.
- It also speeds bone metabolism in fracture sites within the first 2 weeks afte injury.
- Therapeutic ultrasound should not be used immediately after a soft tissue injury or on an infected area.
- Depth of tissue penetration frequency of ultra sound waves.
- lower the frequency ,deeper the penetration.
- The hair over the treatment area should be clipped because the ultrasound is poorly transmitted.
- A coupling gel should be applied to the skin and transducer.
- For lower leg injury the horse can be stood in a tub of water.
