This is an area near to me. My 40 hr. gig is as a designer for people with disabilities. I design and create handicapped accessible housing and equipment. I also modify existing equipment for use by people with one or more limiting factor in their lives. Some years back I rain my left hand through a table saw and was severely injured. I had a finger reattached and had to go through considerable physical therapy ( I used an Autoharp) to regain the 50% use of my left hand that I now have. The nerve damage has taken away the fiddle from me but I still play banjo of sorts and guitar as well. I have replaced the fiddle with a hammered dulcimer. I wonder how many of us out there are playing through a disability and how have we coped. Have we modified our instruments or playing style? What do we do more or less of? Ultimately this will serve as research for a paper in a journal or presentation at a United Cerebral Palsy Convention.
