  • The second is the decrease in pain from the reduction of swelling and edema.
  • The third is the gentle massage of muscle tendons and/ or ligaments in the treated area because no strain is added and any scar tissue is softened.

Types of Effects

  • Thermal effects are due to theabsorptionof the sound waves.
  • Non thermal effects are fromcavitation, microstreaming andacoustic streaming.
