Sound Pressure Wave Principle

In 2001, HealthSonix began its research activities in sound-based therapy to manage pain after learning of the success of the medical application of sound vibration to promote healing and the reduction of stress in hospitals in Scandinavian countries. Following its own laboratory research on people with pain, the company discovered that those with arthritis in particular had a significant reduction in pain and other symptoms of arthritis.

Although the use of sound as such is not new to medicine (high frequency ultrasound is one example), three facts make the HealthSonix technology unique and revolutionary:

1. It is based on distinct and proprietary low frequency sound pulses, successfully commercialized in local markets since 2001;
2. Its effectiveness and safety has been corroborated by over 250,000 individual sound-based treatments, yielding an 80% success rate in reducing and even eliminating pain;
3. It can be safely used in combination with leading pharmaceuticals and over-the-counter products to produce superior treatments outcomes for a variety of medical conditions.

Based on its research, the Company developed the enSonix medical devices for use in medical clinics, warm water swimming pools, and home use products. The enSonix device is computer-controlled and generates precisely-formatted sound pressure waves.

The sound pressure waves generated by the enSonix medical device are believed to work in three ways to provide pain relief and relax muscles:

1. Sound pressure waves stimulate mechanoreceptors in the skin which in turn communicate with the brain thus blocking any other message from getting to the brain - including pain. This is referred to as the pain gate control theory.
2. They also create an exercise effect in the muscles by gently vibrating the muscle fibers: this effect encourages the production and release of endorphins, the body's natural pain killers.
3. Finally, sound pressure waves can increase cell membrane flow and blood circulation, resulting in further pain reduction, muscle toning and relaxation.

The illustration below shows how the sound waves block the pain message from an arthritic knee:
