This student has very little muscle mass - he gets exhausted just from handwriting (he has aides who help him in class; often taking over the task of handwriting when he is too fatigued to continue). As such, I think doing external techniques wouldn't be terribly practical for him. Even if he did learn how to strike, I doubt he'd be able to deliver them with sufficient strength to be able to use them in a practical self-defence situation. And unfortunately he has been a victim of unprovoked bullying before.(sadly there are people out who are willing to attack even wheelchair-bound victims
)
So I need to think of something that he can physically do given his disability, and can hopefully work in a self-defence situation. Teaching this student is definitely going to be a challenge as I'm going to have to disregard the single most core feature of fighting -- stances. As I once heard a Karate teacher say, "If your stance is wrong, all your Karate is wrong." - and this is something that I'd wholeheartedly agree with. Unfortunately you just cannot apply this principle with someone who physically cannot stand. So it flies against everything I've learnt and know about martial arts - and I'll have to teach him the one thing I always tell my other students not to do -- leading with their hands!
So far my ideas are:
+ Modified Silk-Reeling. Silk-reeling is a basic technique I teach to all of my students anyway.
+ Modified Suwari-waza.
+ Modified Push Hands
...any other ideas are welcome, but due to the student's condition external techniques like striking aren't really possible. As such all my ideas atm are confined to more internal techniques.
