Zusammenfassung:The aims of this study were to translate the Michigan Hand Outcomes Questionnaire into the Polish language and to test the measurement properties of its quality criteria. A total of 120 patients with hand complaints completed the Polish Michigan Hand Outcomes Questionnaire and the Disabilities of the Arm, Shoulder, and Hand questionnaire on the first assessment, along with the grip test, pinch test, and pain sore assessed using a visual analogue scale during activity. After 7 days, 76 patients completed the Michigan Hand Outcomes Questionnaire the second time. The Cronbach alpha of the Michigan Hand Outcomes Questionnaire subscales ranged from 0.79 to 0.96. The intraclass correlation coefficient varied from 0.82–0.97, and the Bland–Altman method indicated the Michigan Hand Outcomes Questionnaire total score limit of agreement was −13.2–12.3 and −9.18–9.62 for the right and left hand, respectively. The construct validity revealed a moderate to strong correlation between every subscale of the Polish Michigan Hand Outcomes Questionnaire and Disabilities of the Arm, Shoulder, and Hand, but they only correlated with the grip test and the visual analogue scale, and neither correlated with the pinch test. The study demonstrated properties similar to the original version, validating the belief that the use of this questionnaire in medical practice in Poland is justified.
