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.
