Limited joint range of motion and pain in response to movement are reliable indicators of OA. Physicians, OTs, and PTs can admin- ister the following examinations during the diagnostic process: ● Active range of motion (AROM) measurements should be taken using appropriately sized wrist and finger goniometers. A surface- or dorsal-based goniometer provides more expe- dient assessments in comparison to taking lateral measure- ments of the wrist and fingers (MacDermid, 2015). When mea- suring AROM of a digit, the proximal joint should be stabilized to give accurate measures of the distal joint. When measuring DIP flexion, the PIP can be stabilized either in extension or in flexion to encourage full gliding of the flexor digitorum pro- fundus (FDP; see Figure 6).
