Abstract

Objectives: Work-related complaints of the arm, neck and shoulders (CANS) are frequently occurring. In order to recover from or prevent CANS the workload of the upper extremities needs to be evaluated, however there is no valid questionnaire. The aim of this study was to analyze the construct validity and the test-retest reliability of the Upper Extremity Work Demand scale (UEWD) 2.0. Method: Based on the Dictionary of Occupational Titles (DOT) categories, 54 participants from different levels of physical work demands were included. The construct validity was determined by testing 11 predefined hypotheses about the UEWD 2.0 compared to the Rapid Upper Limb Assessment (RULA), the Maastricht Upper Extremity Questionnaire (MUEQ) posture subscale and, the RAND-36 physical functioning subscale. To determine the test-retest reliability (Intra-class correlation coefficient (ICC) agreement), two measurements were executed. The agreement was determined with a paired t-test and the smallest detectable change (SDC) was calculated. Results: Nine of the 11 predefined correlations were confirmed. Correlation between UEWD 2.0 total and RULA-C was 0.69; UEWD 2.0 and MUEQ 0.30; UEWD 2.0 and RAND-36 0.16; UEWD 2.0 force/posture and RULA force 0.74; UEWD 2.0 repetition and RULA muscle 0.12. With the confirmation of 82% of the predefined hypotheses, the construct validity of the UEWD 2.0 was good. The test-retest reliability was good (ICC agreement = 0.79). There was a significant difference between repeated measures. The SDC was 4.85. Conclusion: The UEWD 2.0 is the first valid and reliable questionnaire to evaluate the workload of the upper extremities. For patients with CANS, we expect that the UEWD 2.0 can be used to detect if the workload might be part of the cause. Further research should investigate if there is indeed a correlation between the UEWD 2.0 and the presence of CANS.
