- 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.
