If you have type 2 diabetes and are suffering from neuropathy, whole body vibration might be able to help you.  Spiral vibration 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.  Vibration machines are able to improve circulation and you may even be able to utilize them for this reason while sitting down and simply having your feet on the platform.  These platforms are also able to help you lose weight, which may reduce your blood pressure and prevent diabetic retinopathy--if you already have retinopathy, it can not undo what damage has already been done, but it may be able to prevent it from getting worse.
