Abstract
STUDY DESIGN: Cross sectional. INTRODUCTION: Measuring wrist range of motion (ROM) is an essential procedure in hand therapy clinics. PURPOSE OF THE STUDY: To test the reliability and validity of a dynamic ROM assessment, the Camera Wrist Tracker (CWT). METHODS: Wrist flexion and extension ROM of 15 patients with distal radius fractures and 15 matched controls were assessed with the CWT and with a universal goniometer. RESULTS: One-way model intraclass correlation coefficient analysis indicated high test-retest reliability for extension (ICC = 0.92) and moderate reliability for flexion (ICC = 0.49). Standard error for extension was 2.45° and for flexion was 4.07°. Repeated-measures analysis revealed a significant main effect for group; ROM was greater in the control group (F[1, 28] = 47.35; P < .001). The concurrent validity of the CWT was partially supported. CONCLUSION: The results indicate that the CWT may provide highly reliable scores for dynamic wrist extension ROM, and moderately reliable scores for flexion, in people recovering from a distal radius fracture. LEVEL OF EVIDENCE: N/A.
