When was her injury? Did she go back to the gym right away after or did you keep her out for a while? My dd has always been back in the gym within a few days of any of her injuries, on her own desire to be conditioning and being with her friends. I have found it also helps with those fears that seem to creep in the longer they are out of the gym.
Having said that, You just have to let her lead the way even if it means ending gymnastics. Some kids don't want to deal with that kind of risk again and you have to respect it. But, with time, she may decide that she does want to go back but she may just need some distance right now.
