Hi Alex,
My recommendation is to have a general idea of significant values for the big outcome measures (like the Core Outcomes). For example, for the FGA, I’d know that <23/30 is the falls risk cut-off and 4-6 points represents a meaningful change.
I wouldn't try to memorize everything for all the outcome measures. You should be in good shape if you can generally interpret how a patient is doing by looking at the scores.
