Patricia -- The only useful suggestion made to me thus far has been the perhaps overly simplified, but common sensical admonition, to keep your nose pointed toward your toes, "noes to toes." But I have my feelers out, now, and I'll relay to you anything I learn. One other contact you might find helpful is Becky Hunt ([log in to unmask] (James Hunt)), whose 75-yr-old mother is a PD backwards faller and who has been working on it for some time, apparently. Please send me anything of interest you come accross. Thanks, John Bachman
