Mark suggested I read some John Brunner, and though he didn't recommend this one in particular, it was all I could find at Gleebooks second-hand a few months ago. I haven't read this sort of classic pulp-ish scifi for a long time, excepting the occasional moldering Asimov, and having looked through quite a few library catalogues and second-hand bookshops they are getting quite difficult to find.
Here Brunner is workman-like, recounting the rise of a mental superman with a broken body to the peak of the "curative telepathy" profession. At the two-thirds point I worried that it would go all Ubik with mental worlds-inside-worlds, but fortunately he dodged that bullet. It's an amiable read, but surely not his best; there are a few non sequiturs in the plot, such as the ready acceptance he finds when he returns to his home town in the last third.
Apparently it was released as The Whole Man in the U.S., which might give you some idea of the narrative arc.
