We'll wait for the neurologist to talk with her before we make any decisions on equipment. It may be something unrelated to the Parkinson's.

This is a 78-year-old woman who is still doing her 1 hour walks about 4 times a week. After we spoke to the pharmacist, we went to a sports store where she bought a $90 paid of new running/walking shoes!

Will update when I have any news at all. Thanks so much everyone!
