-Prescription history
-Physical therapy records
-Employment impact documentation
C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
