May be used to improve scar tissue flexibility and/or reduce muscle guarding and pain. It is a painless technique that uses sound waves at specific intensities. The sound waves are delivered to the pelvic floor through a small sound head or wand. A gel that allows the ultrasound to make a seamless contact to the pelvic floor will be placed on the ultrasound head. The sound head will be moved slowly over the pelvic floor to direct the sound waves to the necessary areas.
