While we of course rock oh-so-very-hard on Rock Band's drums, the pedal just never felt right under our weakling calves. The problem is naturally exacerbated for folks in wheelchairs, since there's no way to avoid the kick drum or re-route it to another button -- at least out of the box. Some folks at Kinetic Communications modded up a doorbell to work as the kick drum button and screwed it to a drum stick. Not the prettiest mod in the world, but it got their wheelchair-bound buddy drumming for about $20, and it shouldn't be hard to replicate their instructions.
