she should keep moving after her adjustment, so take her for a walk or a run round the garden, maybe play catch with a ball just to keep her moving. Then for the rest of the day try to avoid letting her slouch, so sitting on a dining chair doing art at the table would be better than sitting on the couch watching telly. But don't panic if she wants to slouch as long as she gets a bit of a walk immediately following the appointment she will be fine. Just don't put her from the appointment straight into the car for a long ride home unless there is no way to avoid it.
