Reliability and validity of the German version of "the Patient-rated Wrist Evaluation (PRWE)" as an outcome measure of wrist pain and disability in patients with acute distal radius fractures.

The aim was to test the reliability and validity of the German version of the Patient-rated Wrist Evaluation (PRWE) for patients with acute distal radius fractures. To estimate the reliability and construct validity, 44 patients completed a questionnaire booklet containing the German PRWE, the Short Form-36 (SF-36), and the Disability of the Arm, Shoulder, and Hand (DASH) four to six weeks after the fracture, and the PRWE again seven days later. For reliability, the intraclass correlation coefficient (ICC) was 0.
