Ultrasonic Therapy Unit -1& 3

Piezoelectric Effect: An electrical charge sent through crystals inside the transducer wand makes them vibrate, generating sound waves between 0.7 and 3.3 megahertz.


Thermal Effects: Sound waves cause tissue particles to oscillate, generating deep heat that relaxes tight muscles and speeds up metabolic activity.


Mechanical Effects (Cavitation): Microscopic gas bubbles expand and contract in tissue fluids, creating micro-streaming that helps break down scar tissue and reduce swelling
