I suggest you contact the Netherlands Association of Occupational Therapists. I am sure they would be able to answer your questions and/or direct you to who could be of help to you. Another resource for you could be the WFOT Delegate from the Netherlands. You can find her contact information on the WFOT website.
Best of luck to you!
