“…However, low-back-pain studies have shown that averaging does not predict risk well (e.g. Herrin, Jaraiedi, and Anderson 1986; Marras et al 1993; Norman et al 1998). It is worth noting that the ad hoc committee for the Revised NIOSH Lifting Equation did not believe that averaging of variables or Lifting Indexes was an appropriate method.…”

Pooling data from different epidemiological studies of musculoskeletal disorders (MSDs) is necessary to improve statistical power and to more precisely quantify exposure–response relationships for MSDs. The pooling process is difficult and time-consuming, and small methodological differences could lead to different exposure–response relationships. A subcommittee of a six-study research consortium studying carpal tunnel syndrome: (i) visited each study site, (ii) documented methods used to collect physical exposure data and (iii) determined compatibility of exposure variables across studies. Certain measures of force, frequency of exertion and duty cycle were collected by all studies and were largely compatible. A portion of studies had detailed data to investigate simultaneous combinations of force, frequency and duration of exertions. Limited compatibility was found for hand/wrist posture. Only two studies could calculate compatible Strain Index scores, but Threshold Limit Value for Hand Activity Level could be determined for all studies. Challenges of pooling data, resources required and recommendations for future researchers are discussed.

“…Support for these assumptions can be found in both NIOSH documents (NIOSH, 1981(NIOSH, , 1994 and in epidemiological studies by Herrin et al (1986), Bringham and Garg (1983), Anderson (1983), and Chaffin and Park (1973). However recent work by Leamon (1994) suggests that more research is needed in this area.…”

“…Correction coefficients for limits of compressive forces the low-back by manual work. This force is considered a critical stress vector and good predictor of low-back damage (13). The values calculated by an equation published in the NIOSH Work Practices Guide for Manual Lifting (1981, revised in 1991) were accepted as limits for the compressive forces on the disc L4/L5, i.e.…”

SUMMARYAim: The aim of the study was to develop a computational module for the prediction of compressive force on the L4/L5 disc suitable for use in field settings.Method: The value of compressive force is intended to be used as a proxy measure of the mechanical burden of low-back when performing work activities. The compressive force predicted by the module in a particular worker should be compared with the NIOSH limit value of 3,400 N for the assessment of lumbar spine load during manual lifting tasks. Exceeding the limit will be considered as the fulfilment of "hygienic criterion" that should be met to acknowledge low-back disorder as an occupational disease. To develop the computational module we used the ergonomic software TECNOMATIX Classic Jack taking into account the anthropometric parameters of a worker and ergonomic parameters of his/her work activity.Results: We calculated compressive forces on the L4/L5 disc in about 1,300 simulated combinations of various factors influencing compressive force. Parameters which turned out to be crucial for the compression of L4/L5 disc were included in the computational algorithm.Conclusion: Our study was primarily aimed at the assessment of lumbar disorders as occupational diseases. Moreover, the study can contribute to the recommendation of preventive measures to decrease health risks in occupations associated with the overload of low-back region. The graphic maps generated by the computational module enable a fast and exact analysis of particular job.
