Background: To determine normative values for the QuickDASH questionnaire in the elderly Japanese population and their associated factors. Methods: Three-hundred and eighty-one residents between 50 and 89 years of age were randomly selected from residents of a town in Japan. All participants completed a QuickDASH questionnaire. A multivariate analysis was performed to identify associated factors. Results: Males and females aged 70-79 and 80-89 showed significantly higher QuickDASH scores than the 50-59 age groups. Females aged 50 to 59 showed significantly higher QuickDASH scores than males aged 50-59. Motion pain or tenderness at the shoulder and side pinch strength showed a significant effect on QuickDASH scores. Conclusions: The mean QuickDASH score was 5.7. As an associated factor for the QuickDASH, aging, female, and shoulder disorders were confirmed.
