2Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.

3Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.

4Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).

5If you use assistive devices (brace, cane), bring them.
