I have a neighbor who has PD, and his doctor, who also has PD, told him to purchase, and use a machine called "The Confidence Slim Full Body Vibration Platform Fitness Machine." I found them on several sites . . . around $250. The machine is supposed to get you and keep you in shape, which gives drastic aid and relief to those with PD. It is said the machine reduces tremors significantly, though it was not invented for that purpose. Anyone hear anything on this machine?
