Sound energy as a concept, has been used in medical science for several decades, for example, the use of ultra sound i.e. high sound frequencies, is commonly used in modern healthcare. During the 1980′s, Scandanavian and English scientists discovered that low frequency sound waves could also be of benefit, with initial research revolving around the management of children with physical and intellectual disabilities – less agitation, improved range of motion in limbs, better sleep patterns.The Physioacoustic methodology was designed by Petri Lehikoinen, Clinical Psychology and music therapist. From his years of work, we now have a compact device that precisely replicates and controls low frequency sound vibrations. Next Wave's patented Physioacoustic therapy system is a unique method of using low frequencies within the range of 27-113 Hertz for therapeutic purposes such as improving circulation, relieving pain and relaxing muscle tissue. Next Wave systems have been scientifically tested, are FDA (USA) and BSI (UK) listed and are in wide use throughout Europe, United Kingdom, North America, Australia, Singapore and Japan.Physioacoustic therapy affects all body functions, mainly the control center in the brains, the thalamus, but also on other nerve tissue, muscle and connective tissue and the blood and lymph circulation.The technology has been incorporated into a special reclining therapy chair and into a luxurious spa bed. Here are six audio speakers placed connected to a special software program. The speakers produce audible and sensible sound vibrations that will influence the body at cellular level.The unique ability to control the direction of the sound – from bottom to top, and vice versa – will stimulate the blood and lymph circulation. Changing the strength (pulsation) of the sound vibrations will prevent overstimulation.
