I have stairs at home and no bathroom downstairs. The stairs problem kept me occupied and worried for weeks before the operation.
I somewhat improved the stair method
. I use (still) a small pillow (like a livingroom pillow). I also use 2 regular walkers, one for each floor. Going up
: Standing in front of the stairs I lean a bit forward and put the pillow on the third step. I then put my "bad" knee (i.e. the one of the bad foot) on the pillow, and pull myself up putting the "good" foot on the stair below the pillow. This foot is my lever! I then repeat the process: Taking the pillow, putting it on the third step. Knee, "good" foot, etc. Please note: I am rather tall; therefore the 2 stairs interval is right for me. Shorter people will do it with 1 stair intervals. When I get to the end of the stairs I use the rails and/or the wall to raise myself and hold the walker which awaits me there, to go wherever I need. You can also use a chair but u still have to push yourself up. This is the trickier part. Going down
: The lady who first suggested this method advised to go down on your butt. I tried this, but found it abused my upper arms and shoulders, as I also have a "frozen shoulder" situation. Therefore, a revised technique… which is basically the same as going up. You just have to figure a way to get down to the floor level. Facing upwards
, you put a/the pillow on the first or second stair, where you rest your bad knee. Then you send your good foot down to wherever it reaches on the stairs, take the pillow and repeat the process downstairs till you meet your walker.
I use a square 15 inches pillow.
Thru all this process you must hold the rails.
I suggest practicing this procedure. It saved me.
I have more tips, but this will have to wait for tomorrow.
