Today I described someone as being trained to react "more poorly" to a given situation. Her current reaction is poor. It is becoming more poor. So she reacts more poorly. Is this correct? It sounds awkward.

The British National Corpus has 13 cites for "more poorly", and the Corpus of Contemporary American English has 83 (including 8 for "even more poorly" and 1 for "more and more poorly"). Google returns about 826k results. So it's obviously being used and understood. And, as J. M. points out, it's not ungrammatical, either. (Now, if you were asking for possible alternatives, that would be a different question.)
