I like a lot of the responses that have been given so far and I thought I would share my personal experiences. I adapt the style of kempo that I teach to the individual, disabled or not. Everyone has slight differences in their mannerism, body makeup, and ability so each person does things a little different. With that said, I have 2 black belts both promoted over the past 2 years that have had to overcome some major differences. One of them has been blind for her entire life and the only activity she does has been Kempo for the past 20 years. When she came to me 5 years ago none of her previous instructors treated her like a Kempo student she could not even hold a crane stance for more than 4 seconds, so thats what we did first (she also has an obesity problem which hinders her balance) we then took all of her techniques and made them work off of a grab of some sort. I had to level with her and ask if she could hear me punching and if so to teach me, she couldnt so the initial block of most of the techniques were kind of inadaquete so like i said we moved them to touch. Needless to say after 5 years and talking to 2 of my instructors they said to me
"reaching black belt was about personal excellence" and that level is graded on the person not the group. So she tested and passed. The next individual was in a major car wreck and was not supposed to live, let alone walk. he is now doing both with a black belt. So no, neither of these individuals jump through the air, but both have the heart and spirit of a black belt. Side note, the gentlemen who was never to walk, went through the entire black belt test with everyone else and did a great job, Sure he fell a few times, but don't we all, it's the ones who get back up who deserve the credit.
In Peace,
