I'd start with recent research articles, to see who is publishing and if an MD, where they might practice. And also the reference articles they cite, for the same kinds of threads. It's a sub sub specialty and thus expertise is going to be limited, rare.

Second checking out the Foundation for Peripheral Neuropathy

I generally try to stick to articles not older than 5 years, however it's so rare to find the topic covered
