I haven't fallen since I started using my walking stick. It is a trekking pole with a cane grip and shock absorber (so my arm and shoulder joints don't hurt more). It is like this one. http://www.amazon.com/Chinook-...Hiking/dp/B00BNUGCAI
PT didn't do much for me, but maybe it will help you. It seems that you are very active, so I doubt it is deconditioning.
