A Study on Quantitative Evaluation Method for Risk of Work-related Musculoskeletal Disorders Associated with Back Flexion Posture

Abstract
This study tried to develop a basis for quantitative index of working postures associated with WMSDs(Work-related Musculoskeletal Disorders) that could overcome realistic restriction during application of typicalchecklists for WMSDs evaluation. The baseline data(for a total of 603 jbs) for this study was obtained fromautomobile manufacturing company. Specifically, data for back posture was analyzed in this study to have abetter and more objective method in terms of job relevance than typical methods such as OWAS, RULA, andREBA. Major statistical tools were clustering, logistic regression and so on. The main results in this studycould be summarized as follows; 1) The relationship between working posture and WMSDs symptom at backwas statistically significant based on the results from logistic regression, 2) Based on clustering analysis, threelevels for WMSDs risk at back were produced for flexion as follows: low risk(< 18.5°), medium risk(18.5°～36.0°), high risk(> 36.0°), 3) The sensitivities on risk levels of back flexion was 93.8% while the specificities onrisk levels of back flexion was 99.1%. The results showed that the data associated with back postures in thisstudy could provide a good basis for job evaluation of WMSDs at back. Specifically, this evaluationmethodology was different from the methods usually used at WMSDs study since it tried to be based on directjob relevance from real working situation. Further evaluation for other body parts as well as back wouldprovide more stability and reliability in WMSDs evaluation study.
