A couple of years back I had a running injury which resulted in me not being able to walk more than a few steps without assistance (cane, crutches). I realized very quickly how ill-designed the assistive devices - but more importantly the world around us is.
At home I was sliding down stairs because it was hard to use a cane while holding on to the railing - especially since the railing was on the same side as my bum leg (and hence on the same side as the cane). The problem got even worse outside while navigating (often broken) escalators in metro stations, security lines at airport (the cane cannot come with you), streets and even restaurants (busy ones)
Worse was the sympathy and even worse (in some cases) was the look of "Ugh - fine you can have my seat" I used to get.
And then my wife said something to me. She said "you like Dr House why not channel him now"
And so I did. I also got a flame decal for my cane (a la house). I developed a "I dont give a .." attitude. And at home (and in some cases outside) I started using my exercise bands as ties around my waste with carabiners to hook around rails etc. to prevent falls
There are some folks who have started doing this:
