Separate from that I am also inviting people who have extensive experience teaching judo to physically or mentally disabled peopled or those coaching disabled people. I am mostly interested in hearing how you arrived at doing what you are doing ? Did you just experiment and saw as things went along, or where did you get the applied knowledge, or do you simply think it is a wrong attitude to believe that you're approach to judo for disabled should be different.
My overall motive for asking this question is the general absence of such specific courses in most countries or federations. There are a couple of federations dedicated to judo for disabled people, but most of these federations or the responsible government department do not have such courses. These questions have been in my mind ever since I was once asked to referee judo in disabled judoka and refused because I did not have any special training or certification in this area. When I raised that to the officials much to my surprise they responded: "Oh none of us have any training or certifications in that area". Turned out most of them did not have any instructor training or certifications whatsoever. No doubt that a piece of paper does not make you an expert in teaching or coaching or refereeing judo in disabled, but it would attest that certain minimal training has been done and competency has been shown (if the certifications require prior assessments and mandatory internships). That is not to say that I am questioning that there might not be people who perhaps have decades of experience doing this and are very competent in it. It is precisely this kind of information that I hope to find out from the responses you provide here.
