Predictors of chronic shoulder pain after 5 years in a working population

Abstract

The role of psychosocial and physical factors in the development of shoulder pain has now been clearly demonstrated. However, only a few studies have analyzed these associations over time. The main goal of this study was to evaluate the predictive value of work-related psychological and mechanical factors on chronic shoulder pain. A total of 12,714 subjects (65% men) born in 1938, 1943, 1948, and 1953 participating in a French prospective longitudinal epidemiological investigation in 1990 to 1995 Enquête Santé Travail Et Vieillissement (ESTEV) were included. Clinical examination was performed by 400 trained occupational physicians. Personal factors and work exposure were assessed by self-administered questionnaires. Statistical associations between chronic shoulder pain and personal and occupational factors were analyzed using logistic regression modeling. A total of 1706 subjects experienced chronic shoulder pain in 1990, and 2089 experienced chronic shoulder pain in 1995. The incidence of chronic shoulder pain in 1995 was 11% (n=1355). Forceful effort (odds ratio [OR]=1.24 95% CI [1.05-1.44], awkward posture (OR=1.34 95% CI [1.19-1.52]), decision latitude (OR=1.19 [1.04 to 1.35]), and psychological demand (OR=1.19 95% CI [1.06-1.32]) in 1990 were significantly associated with chronic shoulder pain in 1995, even after adjustment for personal factors and previous shoulder pain status. Awkward posture (OR=1.43 [1.25 to 1.63]), psychological demand (OR=1.24 [1.09 to 1.40]), and decision latitude (OR=1.21 [1.04 to 1.41] work-related factors in 1990 were associated with the development of chronic shoulder pain between 1990 and 1995. These results suggest that awkward posture, forceful effort, job demand, and decision control are predictors of chronic shoulder pain at work. Interventions designed to reduce the incidence of chronic shoulder pain must include both mechanical and psychological factors.

“…Low decision authority and job strain were associated with lack of recovery in men. These psychological factors were not reported by Bonde et al [2003] nor in studies on shoulder pain [Miranda et al, 2001;Luime et al, 2004;Herin et al, 2012;Sadeghian et al, 2013]. However, another study found that subjects exposed to job strain had a higher chance of being symptom-free from neck/shoulder pain than those who were not exposed and they could not explain this result [Grooten et al, 2007].…”

“…In 2011, work-related MSDs represented 79% of occupational diseases in France and shoulder disorders accounted for 37% of the MSDs [Caisse Nationale de l'Assurance Maladie des Travailleurs Salariés, 2012]. Previous studies have examined the factors associated with recovery or recurrence of shoulder pain in workers [Miranda et al, 2001;Cassou et al, 2002;Luime et al, 2004;Grooten et al, 2007;Herin et al, 2012;Sadeghian et al, 2013]. However, factors associated with the recurrence of clinically diagnosed shoulder disorder have been little studied in workers [Bonde et al, 2003;Silverstein et al, 2006].…”

<p>Brain Functional Alternations of the Pain-related Emotional and Cognitive Regions in Patients with Chronic Shoulder Pain</p>

“…Patients with CSP need cost about € 4139 per year 4 and CSP causes about 4.5 million visits to physicians in the United States. 5 CSP can lower the quality of life, 6 reduce the ability to work, cause emotional disorders and has substantial socio-economic impact. 7 For these reasons, it is appropriate to explore the neural mechanisms of CSP, which are associated with clinical treatment.…”

“…It has a major impact on health-related quality of life [1]. Disorders of the shoulder muscles and tendons (rotator cuff) are thought to be the most common causes of the pain [2].…”
