I am sure most academic centers would not have a problem or even local physiatrist. Most I am guessing are probably not formal or posted on the websites. It may take some leg work on your part, try to contract the residency coordinator/ or contact local physiatrists, they may be able to accomodate your visit or work something out. In the past I recall AAPMR had a mentorship with students, you might want to check that out too.
