What is it indicated for?

Ultrasound delivered to the body using an efficient couplant provides deep heating effects to body tissues. Ultrasound delivered at a frequency of 1 MHz penetrates to a depth of approximately 5 centimeters while ultrasound at a frequency of 3.3 or 3.2 MHz penetrates tissue to a depth of approximately 1-2 cm.

When therapeutic ultrasound is delivered to the body at intensities capable of generating a deep tissue temperature increase, some or all of the following effects may occur:

1. Pain relief

2. Reduction of muscle spasm

3. Localized increase in blood flow

4. Increase range of motion of contracted joints using heat and stretch techniques.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
