| Abstract |
The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call centre operators. It was conducted in the form of a one-year prospective study among 165 call centre operators in the United States who participated in an earlier randomized ergonomic intervention. Over a four-week period, ERI and 28 potential confounders were measures by means of a questionnaire at baseline. Regional upper-body pain and computer use was measured by weekly surveys for up to 12 months following the implementation of ergonomic interventions. Regional pain change scores were calculated as the difference between average weekly pain scores pre- and post-intervention. A significant relationship was found between high average ERI ratios and one-year increases in right upper-extremity pain after adjustment for pre-intervention regional mean pain score, current and past physical workload, ergonomic workstation design, and anthropometric, sociodemographic, and behavioural risk factors. No significant associations were found with change in neck-shoulder or left upper-extremity pain. Findings suggest that ERI predicts regional upper-extremity pain in computer operators working ≥20h per week. Control for physical workload and ergonomic workstation design was essential for identifying ERI as a risk factor. |
