Aims: (1) To evaluate an active method of surveillance of musculoskeletal disorders (MSDs). (2) To compare different criteria for deciding whether or not a work situation could be considered at high risk of MSDs in a large, modern shoe factory. Methods: A total of 253 blue collar workers were interviewed and examined by the same physician in 1996; 191 of them were re-examined in 1997. Risk factors of MSDs were assessed for each worker by standardised job site work analysis. Prevalence and incidence rates of carpal tunnel syndrome, rotator cuff syndrome, and tension neck syndrome were calculated for each of the nine main types of work situation. Different criteria used to assess situations with high risk of MSDs were compared. Results: On the basis of prevalence data, three types of work situation were detected to be at high risk of MSDs: cutting, sewing, and assembly preparation. The three types of work situations identified on the basis of incidence data (sewing preparation, mechanised assembling, and finishing) were different from those identified by prevalence data. At least one recognised risk factor for MSDs was identified for all groups of work situations. The ergonomic risk could be considered as serious for the four types of work situation having the highest ergonomic scores (sewing, assembly preparation, pasting, and cutting). Conclusion:The results of the health surveillance method depend largely on the definition of the criteria used to define the risk of MSDs. The criteria based on incidence data are more valid than those based on prevalence data. Health and risk factor surveillance must be combined to predict the risk of MSDs in the company. However, exposure assessment plays a greater role in determining the priorities for ergonomic intervention. W ork related upper limb musculoskeletal disorders (WMSDs) are a heterogeneous group of disorders which include peripheral nerve entrapments, muscle disorders, tendinitis and tenosynovitis, and vascular disorders. The work environment and performance of work contribute significantly to the development of such disorders.1 2 As in other industrial countries, workers' compensation (WC) claims for WMSDs in France are increasing in a wide range of occupational groups.3 As the risk of musculoskeletal disorders (MSDs) is high in the shoe industry, a surveillance programme for MSDs was implemented to identify and reduce work related risk factors in a large shoe factory.Surveillance is defined as the ongoing systematic collection, analysis, and interpretation of health and exposure data in the process of describing and monitoring a health event.2 The main objective of the surveillance of MSDs is to determine the need for action and to plan, implement and evaluate ergonomic intervention and programmes.2 4 Different systems are available for routine analysis of health and exposure to risk factors. Passive surveillance using WC and sickness data is easy to implement, even in small sized industries.2 4-6 Active surveillance involves a workplace specific system to ident...

“…Ergonomic risk assessments are based on integrated models of MSI causation which account for the role of physical exposures in the precipitation of MSIs. Descriptions of several ergonomic risk assessments have been published and many of the methods have demonstrated predictive validity [1,2]. Consensus among the authors of the risk assessments as to which exposures should be considered and the relative role of the exposures in the causation of MSI has not been reached however.…”

The objectives of this study were to examine the agreement between 5 ergonomic risk assessment methods calculated on the basis of quantitative exposure measures and to examine the ability of the methods to correctly classify 4 at risk jobs. Surface electromyography and electrogoniometry were used to record the physical exposures of 87 sawmill workers performing 4 repetitive jobs. Five ergonomic risk assessment tools (rapid upper limb assessment [RULA], rapid entire body assessment [REBA], American conference of governmental industrial hygienist's threshold limit value for mono-task hand work [ACGIH TLV], strain index [SI], and concise exposure index [OCRA]) were calculated. Dichotomization of risk to no risk and at risk resulted in high agreement between methods. Percentage of perfect agreement between methods when 3 levels of risk were considered was moderate and varied by job. Of the methods examined, the RULA and SI were best (correct classification rates of 99 and 97% respectively). The quantitative ACGIH-TLV for mono-task hand work and Borg scale were worst (misclassification rates of 86 and 28% respectively).

Abstract:Ergonomics approaches to risk of musculo skeletal disorders are often reactive rather than proactive, an approach supported by a lack of ergonomics expertise, especially in small to medium size companies. However, the EU framev\^ork directive on health and safety at work (89/391/EEC) demands a comprehensive risk assessment by the employer. Further, the machinery directive (89/392/EEC), demands a comprehensive risk assessment at an early design stage. Presented are the results of field studies that have identified suitable risk evaluation methods for electronics assembly and rework tasks. To assist nonexpert ergonomists, a risk reduction module is also presented. Combined, the risk evaluation and risk reduction approachs presented here provide a framework for reducing musculsoskeletal disorders in line with EU safety directives.
