Dear Majedah,

You will have to be a little patient.
I have posted your question to more than 15 paediatric physiotherapy organisations around the world. I cannot expect answers straight away.
I do know there are a few possibilities in Bad Ragaz Zwitserland.

go to Courses – Klinik Valens

on the ndta website a link to the Wikipedia reference-linkBobath courses NDTA™

on the sensory intergration website a link to their courses Course schedules | sensory integration network

will get back to you with more details once I have them.
Maybe you can start by looking at the above websites

kind regards

Esther
