Yes, but even that subset of people are not all disabled in the same way, and aren't going to find the same things useful. I work in a pharmacy, and when people want their elderly parent to get a walker, we always say "What does [parent] want?" Sometimes they want a cane! Sometimes they just want one of those walkers with seats because they're fairly steady on their feet if they can have a rest every now and then, and the area through which they walk doesn't have seats, or not in the right places. Sometimes the parent is too tall for the more common walkers (I'm fairly tall and when I needed to get a gripping stick to pick things up off the floor, I had to find an extra-long one). Sometimes they just want to get a disabled parking permit so they can be closer to the shops and not have to walk through uneven and dangerous carparks, but are totally fine once inside.

And that's just one example of fairly common assistive technology.
