Risk factors for incidence of rotator cuff syndrome in a large working population

Objectives: The aim of this study was to assess the effects of personal and work-related factors on the incidence of rotator cuff syndrome (RCS) in a large working population.
Methods: A total of 3710 French workers were included in a cross-sectional study in 2002–2005. All completed a self-administered questionnaire about personal factors and work exposure. Using a standardized physical examination, occupational physicians established a diagnosis of RCS. Between 2007–2010, 1611 workers were re-examined. Associations between RCS and risk factors at baseline were analyzed by logistic regression.
Results: A total of 839 men and 617 women without RCS at baseline were eligible for analysis. RCS was diagnosed in 51 men (6.1%) and 45 women (7.3%). The risk of RCS increased with age for both genders [odds ratio (OR) 4.7 (95% confidence interval [95% CI] 2.2–10.0) for men aged 45–49 years and 5.4 (95% CI 2.3–13.2) for women aged 50–59 years; reference <40 years]. For men, the work-related risk factors were repeated posture with the arms above the shoulder level combined with high perceived physical exertion [OR 3.3 (95% CI 1.3–8.4)] and low supervisor support [OR 2.0 (95% CI 1.1–3.9)]. For women, working with colleagues in temporary employment [OR 2.2 (95% CI 1.2–4.2)] and repeated arm abduction (60–90°) [OR 2.6 (95% CI 1.4–5.0)] were associated with RCS.
Conclusions: Age was the strongest predictor for incident cases of RCS, and arm abduction was the major work-related risk factor for both genders. Lack of social support was a predictor for RCS among men.

Performing Artists, Part 2

Work: A Journal of Prevention, Assessment and Rehabilitation. Volume 41, Number 1 / 2012

Performing arts health (PAH) as a field of research may be relatively unknown to some readers. It is my intent in this second editorial, therefore, to highlight some of the similarities and differences between this field and the field of work disability (WD), broadly construed (as in this journal) to include prevention, assessment and rehabilitation.
Readers will be familiar with the significant economic and societal burden of work-related health concerns. In 1999, the World Health Organization (WHO) estimated that occupational injury and disease globally accounted for 800,000 deaths and 38 million disability adjusted life years (DALYs) [1]. Closer to my home,
in Canada, the total direct and indirect costs of occupational injuries to the Canadian economy was estimated at $19 billion in 2008, or $567 per Canadian. These data include only costs associated with claims that were processed. We know, of course, that many injuries and illnesses are not claimed, and in a socialized system of healthcare, those costs are considerable.

Ergonomic Checkpoints in Agriculture

The result of long-term collaboration between the ILO and the International Ergonomics Association is a manual compiling 100 illustrated examples of practical ergonomic improvements that can be achieved at low or no cost. The checkpoints each describe an action, indicate why it is necessary and how to carry it out, and provide further hints and points to remember.
They focus on ergonomically designed tools and on best techniques for handling materials and arranging workstations, physical environments, welfare facilities, teamwork methods and community cooperation. This invaluable training tool is designed for all those concerned with creating a better workplace in agriculture and rural settings: employers, supervisors, workers, inspectors, safety and health personnel, trainers and educators, extension workers, engineers, ergonomists and designers.

Prospective evaluation of the 1991 NIOSH Lifting Equation

An epidemiological prospective cohort study of the ability of the 1991 NIOSH Lifting Equation to predict loss of time from work due to low back pain (LBP) or to predict reports of LBP followed 515 industrial workers in jobs requiring manual handling for 18 months. Baseline measurements were made of their jobs, histories of musculoskeletal trouble and of psychosocial variables. Longitudinal analysis of tasks was based on 367 subject/job combinations.
The strongest predictor of future LBP was a history of LBP. No relationship was found between the Composite Lifting Index (CLI) and either the incidence of lost time due to LBP or the prevalence of LBP (adjusted Hazard Ratio (HR) = 1.0, 95% Confidence Interval (CI) 0.9 - 1.1). The CLI is not useful as a method for assessing risk of LBP due to manual handling.
The maximum value of the Single Task Lifting Index (STLI) gave an adjusted HR of 1.1 (95% CI 0.9 - 1.4). It too is not useful as a method for assessing risk of LBP due to manual handling.
There is a need to develop better methods of assessing risk of LBP from manual handling, focusing on ways of combining risk factors and exposure to multiple tasks.

A classification of methods for assessing and/or preventing the risks of musculoskeletal disorders

The ETUI has recently published a guide showing 15 methods for evaluating and preventing the risks of musculoskeletal disorders (MSDs) in the workplace. The methods are classified into three categories depending on the skills needed to use them: detection – analysis – expertise. Through this publication, the ETUI seeks to encourage the participation of workers and their representatives in the detection and prevention of MSDs.
