I was thinking of how some horses panic in a confined space and immediate action is required to stop them injuring themselves.
It's not an exact parallel, but I once had dealings with a Shire X who managed to get a front foot stuck in a piece of farm machinery.
The local fire brigade had to attend to help free him and during that process he nearly sat down, either through fatigue or panic.
It would certainly have broken his leg and been the end of the poor chap.
However, several of us made an almighty effort to support the back end and managed to keep him upright while the fire brigade did their stuff.
