Hi Esther,
our OT is using the Sensory Profile (www.SensoryProfile.com) by Winnie Dunn, but all the children I'm working with are also seen by other professionals. Every child has a "sensory diet"(that's the outcome of the sensory profile) which they follow every day in school.
We have seen improvements in the children who are receiving Physio and at the same time following their sensory diet. It's just very complex as the children I'm working with are on the lower end of the spectrum and most of them are non-verbal and don't follow instructions or copy/mimic any movement.
Hope this is helpful
Kind regards,
wullie
