Effectiveness of an ergonomic intervention on the productivity of workers with upper-extremity disorders--a randomized controlled trial.
OBJECTIVES The aim of this study was to investigate the effectiveness of an ergonomic intervention on  productivity loss at work caused by upper-extremity disorders ( UED ) . METHODS Workers with medically verified UED were invited to participate . The intervention consisted of a physician contacting the worker 's supervisor and an occupational physiotherapist conducting an ergonomic assessment at the worksite . Before and after the intervention , the employees self-assessed UED-related productivity loss ( ie , decreased quality and quantity of the daily work output ) . We tested for differences between groups at 8 and sub-sequently 12 weeks . We also applied generalized estimating equation ( GEE ) to analyze repeated measures data . RESULTS Altogether 177 employees were r and omized . The overall participation rate was 88 % . At baseline , 54 % of the intervention group and 58 % of the control group reported productivity loss . The magnitude of productivity loss was 17 % and 20 % , respectively . At 8 weeks , both the proportion and magnitude of productivity loss were lower in the intervention than the control group , but the differences were statistically significant only at 12 weeks ( proportion 25 % versus 51 % , magnitude 7 % versus 18 % , P=0.001 for both ) . Using GEE analyses , we also found the differences to be statistically significant ( proportion 38 % versus 52 % , magnitude 12 % versus 18 % ) . The intervention only benefitted employees with 0 - 20 % loss of productivity at baseline , not those with a higher initial productivity loss . CONCLUSIONS Early ergonomic intervention , in addition to adequate medical care , is effective in preventing and restoring self-reported productivity loss associated with UED
