Even if the nerve is cut or other things permanently reduce your ROM, there are many adaptive techniques to do about anything you need to do. For many, radiation cuts of nerve and blood flow to muscles that eventually atrophy. The trapezius is one of the first and that controls the pass off from about 50-90 degrees when lifting the arm. Also, some get scapular rotation muscle atrophy and that's the other group of muscles used to lift the arm above straight out.

I lost the ROM in both arms around year 5 but I still try to do jumping jacks. It makes no sense considering how light the arm really is and how little extra force is required to get it moving. If you lay on your back and can get full ROM, it may be somewhat limited, even after PT. I spent a few minutes almost every day for 18 months to do a jumping Jack and it isn't pretty and it wasn't sustainable for long.
