Sonopuncture is based on the same principles of acupuncture, however as opposed to the manipulation of needles in the skin, sound waves are used instead of these needles. For sonopuncture special sound heads, some similar looking to tuning forks, are used to generate a beam of inaudible ultra-sound. These devices can produce concentrated beams of sound that range from two to five millimetres in width.
The human ear can hear sound waves with frequencies between 20 to 20,000 cycles per second. Sound waves with a frequency above twenty thousand cycles per second are too high pitched to be heard by human ears and are called ultrasound, and range from various frequencies between 750,000 to 1,000,000 cycles per second.
Usually, sonopuncture requires that these concentrated beams be produced anywhere from 15-45 seconds long. For ultrasound waves to be able to work, a proper medium to conduct the sound is necessary. Normally, sound waves we hear are easily conducted through air, however ultrasound is very poorly conducted through the air. They require gels or oils between the treatment head of the device and the skin to conduct the sound into the body.
The sound waves only penetrate 5-8 centimeters deep into the skin, just deep enough to pass through the fat layers and into the muscle. Fat is a very good conductor of these sound waves and does not absorb or diminish them much.
Sonopuncture is also a very good at healing tissue. Applying the sound head over the area that is infected, like a small abscess or a wound that is not healing, improves the blood circulation in the area being treated and causes an increase in white blood cells and antibodies in area.
Sonopuncture is very good at breaking up areas with a reduced blood supply, like fibrous tissue or connective tissue, and helps to heal and remove that scar tissue by breaking down the fibrous tissue with an increase in blood supply, thus improving and speeding up the healing process.
