No, it appears to be a case of child abuse, completely unrelated to scientology.

I suppose you could say "this is the kind of thing that can happen when you force people to run for hours on end, non-stop, like what they have done in the RPF".

I do not know much about RPF. I do not know if they force RPFers with bad stats to run around in circles.
The girl was abused by her idiotic grandmother.

I don't really see too much difference between an idiotic grandmother forcing the girl to run and an idiotic cult forcing their members to run.
