Objectif : Cette étude a permis de déterminer à quel moment les douleurs musculo-squelettiques (MSP) des extrémités supérieures indiquent une baisse de la performance au travail, afin d’évaluer la nécessité d’une prévention secondaire des troubles musculo-squelettiques.

Objective: This study identified when musculoskeletal pain (MSP) in the upper extremities indicates lowered work performance to gauge when secondary prevention of musculoskeletal disorders is needed. Methods: Seven hundred thirty-three subjects from 12 manufacturing or healthcare facilities in Washington state participated. Work performance was measured by the Disabilities of the Arm, Shoulder and Hand work module (DASH-Work). Each DASH-Work score was compared to the mean among U.S. workers to determine if workers had lowered work performance. ROC curve analysis was conducted to find the cut-off in a composite MSP index (summing MSP intensities in shoulders, elbows/forearms, and hands/wrists; range 0 to 24) to detect lowered work performance. Results: The MSP index score of 2 achieved the best balance between sensitivity (0.79) and specificity (0.69) in detecting lowered work performance. Conclusions: To prevent reduced work performance, moderate or multisite pain may require proper management.
