re: How many of you have to rely on this tool like this lady?

I have used that device. Let me explains for all you immature people who feel good by ridiculing others.

At age 72, the most helpless feeling you can have is during the recovery from a level 3 back fusion surgery at L2, L3 and L4. Your recovery in the surgical unit will last for 3 days. During this period, you are bedridden.
You can only lay on your back. You get lifted from the bed and carried to the toilet. When done, they lift you and then they wipe your butt since you are unable to turn even slightly. Yes it is very demeaning to need someone to wipe your butt.

You then get sent to a rehab hospital for physical therapy so you can learn how to walk again, takes about 14 days. During this time, you learn how to transfer with their help to a device that they use to roll you into the toilet. Once done with your bowel movement, you get handed a tool very similar to what that woman was using so you can learn how to wipe your own butt. The reason you use that tool is the exteme pain you feel when you try to pivot or bend. Your first victory is being able to stan up from the wheel chair and transfer to a walker. Then comes the great day when you manage to walk 10 feet by yourself using the walker.

Finally you get sent home where fortunately you have a bidet.

So to all of you who ridiculed that poor woman, I sincerely hope you have no back surgery in the future that will require you to use that device. But if it does happen then it serves you right for ridiculing people who are having difficulties.
