Philadelphia neck brace

[SPR2]

A friend has one of these after fracturing 2nd and 5th vertebrae falling from her horse;(
She feels the need to support shoulder/arm to ease pain but a sling seems out of the question as that would be pressure on the neck. Any alternative suggestions anyone please?

Tape her arm to her torso or chest? Not convenient/practical but it will spread the load. Or wear trousers with pockets and keep hands in pockets?

Or wear a loose belt around the waist and hook her thumbs. Should take some of the weight off her shoulders and put it around the waist.

Or cut her arms off.
