After reading that vibration plates had been built into the space stations, for the spacemen to exercise on - it doesn’t take up any extra space - and my local football club bought a couple for footballers to train on, I paid a local gym about £3.00 for a 10 minute try out. Bought one that I can stand on, which has handles , so you always have something to grip onto, if you think you’re going to fall. Programmes 1-10, so you can control speed etc. my 81 year old friend has had one for 10 years, suffers from restless syndrome, 3 minutes on her machine (often at 3am ) means that she can sleep all night. If I suffer from back/ leg pain, I put on highest setting and and ‘lean’ until I feel the vibrations hit the pain . Put ‘vibration plate’ into a search engine and look at all the information.
