Hi - I've been lurking on the DisAbilities board for some time. I've learned a lot from the collective wisdom and experience of the generous folks on the board and I'm hoping you can help me with a specific problem my family is having with regard to mobility. Our DD 25 has Prader Willi syndrome, a complex genetic disorder. Along with a whole host of other medical and behavioral issues, DD has low muscle tone, ligamental laxity, some serious joint problems (mostly knees and back) and coordination issues. We have been pushing her in a manual wheelchair in the parks for years now, to help with her endurance and pain issues. It's worked pretty well for us up until this point. But she's an adult now and we are both getting older ourselves and starting to fall apart a bit (DH is 65 and I have back problems). DD can't push herself in the manual chair because of her low tone. She can't use an ECV because she also has a pretty significant intellectual disability and can't navigate through the crowds - she can't plan where to "drive" safely and she has NO reflexes...the first person who steps in front of her or stops suddenly is going to get run over. We think a reasonable solution to this problem would be to find something that's powered like an ECV (so it's not dependent on our pushing) but that we could "drive" while walking next to or behind her. Does anyone know of such a product? Thanks in advance for any advice or recommendations anyone can make -- and have a magical day!
