Abby,

If you need to be pushed in the rollator, then you need a wheelchair. A rollator is absolutely not designed to be used as a transport device, except in an emergency. The fact that you are making plans to use it as such, and even modifying it, is proof of that. What you are doing is unsafe.

I would suggest looking into a lightweight travel chair, just to keep in the car. Use that for going into restaurants and such and save the walker for use within the house.

In your case, I think you are a long way from being "overtreated." Having a talk with your neuro would probably be a good idea. Ask him/her what he/she would be comfortable prescribing for you and then research and go from there.

Good luck!
