Hello again @isabelle7!
Yes, PT and OT can teach and instruct on many proper techniques. Here are two others that have helped me:

1. Dishwasher: Move everything to the top. My flatware holder could be lifted out & moved to the top. I understand there are dishwashers made that are top loading only but was not able to buy a new dishwasher!! So while I was recuperating I only used the top of my dishwasher. Large plates were an issue as they did not fit on the top. I had a stockpile of paper plates from various parties throughout many years and used all of them up. You will need to run your dishwasher more frequently. Another option is to wash some dishes by hand if you can avoid bending.

2. Bed making: I did make a significant investment & got an adjustable bed frame. The head & foot of the bed can be lifted to put on the fitted sheets. For the top sheet when the foot is lifted you can tuck & fit the sheet so you will not need to bend. Maybe won't be perfect;)

God Bless us all! Enjoy the beautiful day.
