Thanks but I violently disagree.
Each small movement hurts nearly as much as a larger one. Therefore the cumulative small movements necessary to use your techniques hurt more than one sweeping swing into a standing position. The small movements constitute unmitigated torture. Trust me on this point, I KNOW.
The helper makes it easier to do the sweeping motion but you can set up straps to do arm pulls instead. This gets the pain over much faster. The pain is just as accute but of much shorter duration.
If you have the opportunity to do your technique to someone again, please don’t. You will be doing them a big favor.
The thought of this torture is what led me to the sitting-sleep solution which is vastly superior to any other alternative.
As I clearly pointed out, I have never suffered from a broken rip.
I also made a point to make it clear that these suggestions offered for your consideration, came from my experience of recovering from heart surgery.
It’s unfortunate that your reaction was to violently disagree.
Heck, here’s another tip... Take a couple of swigs from a bottle of whisky and stuff a piece of leather into your mouth before you get up.
