That magnificent imagination that kids have and that we somehow tend to lose as we grow up (why is that?) is apparently a powerful ally in attempts to reduce the frequency and impact of abdominal pain in kids. Rather than describe it badly, have a look at the BBC coverage of it here ‘Children can be taught to use their imagination to tackle frequent bouts of stomach pain’, and the abstract here ‘Audio-Recorded Guided Imagery Treatment Reduces Functional Abdominal Pain in Children‘.
The abstract includes a link to the pdf of the whole paper which, it seems, is free. Congratulations Pediatrics.
