I've read about it but I'm not sure I fully understand what that thing is supposed to do. Vibrate the hell outta you?
Here are some claims on the Power Plate website:
"Power Plate has become an important training and injury/rehab device for the Chicago Bulls.
Power Plate has proven to be a very effective and popular training modality with our players and has demonstrated impressive results even after a short period of use - increasing their strength, flexibility, metabolism and circulation. All of our players are reaping benefits from using the Power Plate - improving their speed/quickness, jumping ability, balance and coordination. Additionally, Power Plate has proved to be a good remedy to soreness and pain reduction, while accelerating the injury / rehab cycle."
-- Eric Helland, Conditioning & Rehabilitation Coach, NBA Chicago Bul

"We are still excited about the response we are getting from our clients.
One of our MS patients is walking so much better with improved balance and gait. Another client with osteoporosis just had a bone scan and despite just working out sporadically for three months she experienced her first increase in bone density after being on Actonel and Fosamax for several years."
