C&P Exam Tips

1Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.

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.

6Describe daily activity impact: work, sleep, household tasks.
