I originally posted that same link @pbnew. As well as the update by Margaret on contraindications.

The heading for the long list I posted in my prior post reads: "Registered equipment manufacturers have identified a number of whole body vibration therapy contraindications and suggest that individuals who have one of the following conditions should not partake in WBV training:" I took this to mean ANY whole body training, not just high intensity.

I guess we need to be careful with just about anything. But a few people on these posts are using the vibratory plates (carefully I'm sure) and seem to be experiencing an easier of old pains. I watched a video about the tech, an interview with a professor at Harvard, who stressed that the 'healing or bone stimulation' occurs when the intensity is below 30-40 hz. I'll try to find it and post it. Thus is not the same thing but my friend's broken Nick's healing to a halt until the neurosurgeon added a soft collar than generated ultrasound on a schedule. The top two vertebrae were broken into pieces so brand-new bone had to grow to fill in the gaps between them. It was amazing to look at the CDs of the CT scans before and after the ultrasound was added. It looked like healing on steroids. My friend could never feel or sense when the collar was on so it was a very subtle energy. Maybe the very low frequency vibrating plates are similar? People need to read up on this, or any new thing, before trying it though and proceed, as always, carefully.
