Oh, nice.
Looking at their
website (which still has placeholder text in some spots) it looks like the acute care hospital runs its own acute neuro rehab unit, so after a stroke patient has stabilized they can just be transferred into stroke rehab instead of having to go to a different facility.
One of the hospitals here does the same thing, and it's a really intense rehab program. They're also very in-demand, and thus picky about which patients they'll take: if someone's refusing to work with therapy, if someone would rather whine to be wiped than use their off-hand, if the stroke caused crippling cognitive deficits, if a patient was demented before and now they're demented
and hemiplegic, they're not a rehab candidate.
