I would do away electives at programs you would consider a "reach". If you don't have any programs in mind, then would go for the "name" programs so will get possibility of getting "name" recommendations. PM&R is a SMALL world. Physiatrists know each other so LORs mean a lot.
In the Northeast/tristate area would recommend Kessler, Rusk (although has gone down hill a bit, there are still some name attendings), Temple, Jefferson.
Would recommend doing both inpatient and outpatient to be balanced.
Go where you can get housing. Those costs can add up.
If you like smaller programs, highly recommend doing a rotation at JFK.
