Maybe you could post your question in the American Rehab Nurse's listserv. I think I read in a rehab nursing journal that there are nurses with masters in rehab nursing, who are members of the listserv. The URL is http://www.rehabnurse.org
(click on electronic mailing list to join the listserv)
You may also want to look in a guide to nursing programs
, such as Peterson's Guide to Nursing Programs: Baccalaureate and Graduate Nursing Education in the U.S. and Canada. Princeton, NJ: Peterson's Guides. or National League for Nursing. Annual Guide to Graduate Nursing Education. New York, National League for Nursing
Keep us posted if you find out anything.
