Dr Tracy Newkirk in San Rafael, CA has designed a brace for TOS. I was tested with it as were many and it did seem to help. I'm not sure where he is with it but my understanding is that it's still in the development stage with a number of people wearing prototypes. I've been waiting for it for a long time. Dr Newkirk retired but maybe you can find a phone number for him and call to inquire. Also, towelhorse, a member here designed his own brace. It's different than Dr Newkirk's one but you could search his postings and find a lot of info about that one.
