it's the abduction, adduction machine. the sitting thigh-squeeze machine is how most know it. i was just trying to be helpful with describing it using my the best o-t definition.
if it is your adductor muscle group, building up the muscle can help make it stronger, and less likely to strain.
as far as it band, my pt never had me use the roller foam. i do it regularly anyway, but he didn't suggest it, though. i stretch for about an hour each day, btw.
ETA: as far as stretching for that muscle group, i do:
-squatting and rocking back and forth
-frog stretch [position how it sounds--knees on ground, arse in air, trying spreading and hold for a 10 count]
