It stands for Intervertebral Differential Dynamics therapy. If you go to www.IDD.com a lot of information about it will come up. Evidently it has been around for a while and is providing non-surgical relief for a lot of people, according to news articles and the centers that administer it. If you don't find it, let me know and i;ll be glad to send more info.
