If you have aches and pains, spiral and sound vibration are the machines that will help you. Spiral machines have two totally different motions--Triplanar (up-down/front-back) and Pivotal (see-saw) that can be used independently or together. When used together, these two motors make a figure 8 motion.  This is an extremely gentle motion on the gel areas of the spine and joints, with many benefits such as lymphatic drainage, improved circulation, improved bone density, pain reduction, detoxification and muscle building on the higher hertz ranges.  Sound vibration machines use high powered speakers to create very smooth, soothing vibrations. These vibrations relax you, detox you, relieve pain and can also build muscle on higher settings.  Sound vibration is also the most gentle vibration on the body. Both of these vibration types will reduce pain by helping to release endorphins.  Endorphins interact with the opiate receptors of the brain to reduce our perception of pain.
