kinemedic makes products for the neuro-ifrah people... i like their AFO (perfect-response orthotic) and some of the hand stuff... Home
saebo ( Splash ) makes the BEST hand splint i've ever seen... i'm not too thrilled so far with the actual saebo-flex thing that supposedly works to increase finger extension, but the saebo-stretch splint is great...
the neuro-ifrah people offer a course for CPOs... i don't think you can sell or market the saebo stuff as it belongs the patents belong to those kids, but at least you can get an idea of a splint that works well verses ones that are crap...
