Reddit reviews Prestige Medical 621-blu Cotton Gait Belt with Metal Buckle Blue

I'm going to second the straps/gait belt for this first part of her illness, especially since you are in the getting stronger phase. It is essentially a belt you put around her waist to give you better leverage/grip in helping her to get up out of a seat. If she still needs your support after that it provides some place for your hands to be for balance and grip should she start to falter. There are videos online to teach the best ways to use them and you can always as a PT if she is seeing one.

I think it will be an asset to you while she still has use of her legs to maintain her independence and keep some strain off of your back.
