Tom, My experience is the same as Martha's. When John arrives in a poorly lit room, he freezes. I know, it usually coincides with going through a doorway but poor light does induce more freezing. As a therapist, I used to try all sorts of different colours on the floor, walls, etc with my patients and it always worked during therapy. But what about every day? I am at the moment in the process of redecorating part of our house and I have wondered if there was a way making walking easier for John. I find accomodation a problem. When working with patients I had to renew the coloured patterns often if I wanted the facilitation process to go on working.( I am not going to redecorate every week). Incidentally, I totally agree with you about swinging the arms, not just useless but confusing. Obstacles on the floor help with walking and walking on uneven ground also. Difficult in one's home!
