How to Select the Frequency
|
The frequency determines how deeply the ultrasound waves can penetrate the body. The lower the frequency, the longer the wave; therefore, lower frequencies can penetrate the body deeper. For sports injuries, chronic inflammation, and arthritis, the frequency typically used is 1-3 MHz.
At 1 Mhz, the ultrasound waves can penetrate up to 1.6” into the skin. This frequency is recommended for acute or chronic injuries and pain, such as bone injuries and arthritis.
At 3 Mhz, the ultrasound waves can penetrate up to 0.8” into the skin. This frequency is recommended for beginners and post-exercise recovery. It can treat the same conditions as the 1 Mhz waves but at a milder intensity.
At 5 Mhz, the ultrasound waves can penetrate up to 0.2” into the skin. This frequency is recommended for skin & facial rejuvenation, fat removal, cellulite, scars, scar tissue, sunburn, bruises, and superficial cuts and scrapes. The waves at this frequency don’t penetrate deeply enough to affect the tendons, so it’s not used for treating injuries.
