Musculoskeletal disorders and productivity

Conclusion

On balance, the evidence supports an association of higher productivity increases with lower MSD rates and greater reductions in MSD rates. Across all industries for which data were available, lower MSD rates were significantly correlated with higher productivity increases. Since both changes in MSDs and in productivity have many varied causes, the effects of efforts specifically intended to reduce MSDs are difficult to isolate from these data. Nevertheless, in two subsets of industries those effects may be more likely to be discernible: industries with the largest reductions in MSD rates would be more likely to have made changes intended to reduce MSDs, and industries with lower productivity growth may reduce the effects of unrelated productivity gains on MSD/ productivity observations. Statistically significant correlations between reductions in MSDs and increases in productivity were found among both of these groups. In addition, among industries with the highest MSD rates in 1992, the extent of implementation of ergonomic controls was significantly correlated with increases in productivity.
