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.
