Investigation of Correlation Result of NORDIC Questionnaire (wrist & hand) with DASH Questionnaire

Introduction: Work-related musculoskeletal disorders occur predominantly in the upper limbs and cause disability. When it comes to the perception of people for their abilities, Questionnaires are useful and valuable tools. Questionnaires can be used to measure the symptoms of disease and disability. We decided to evaluate the correlation result of the NORDIC questionnaire (wrist & hand) with the DASH questionnaire. 
Materials and Methods: The study was a descriptive-analytic and cross-sectional one and was carried out among 82 female assembly workers. To evaluate the correlation result of the NORDIC questionnaire (wrist & hand) with the DASH questionnaire, chi squire and spearman have been used. Data analysis was carried out by using SPSS 20. It is noteworthy to mention that a P-value <0.05 was considered significant. 
Results: In this study, the results of the DASH questionnaire with the studied variables were similar to the results of the NORDIC questionnaire (wrist & hand). Moreover, in the majority of questions, there was a significant relationship between the two questionnaires (P value <0.05). The average score of DASH was obtained at 19.65 ± 14.85 and 65.9% of the people had a mild upper limb. Moreover, 76.8% of the participants had distress in the wrists area, among which, 46.3% had mild discomfort. 
Conclusion: According to the results the DASH questionnaire is a useful tool for industrial and occupational issues. Therefore, due to the high relationship between the two questionnaires, the DASH questionnaire could be used instead of the Nordic Questionnaire (Wrist and Hand).
