Despite a poor understanding of the word evidence again, i agree 100% with ginger. Having undertaken most of my study in switzerland prior to a 30yr career in uk athletics and gynastics including 5 olymipics games I have seen great variation in the education of english undergrads. Fortunately there seems to be vast increase in the use of evidence based practice in europe which appears, based on the previous posts to now superseed that of some antipodeans.
Hopefully your daughter's therapist will be using the clinical reasonong and evidence based practice expected. it sounds like he is!
