AIMS To explore the precision of task based estimates of upper arm elevation in three occupational groups, compared to direct measurements of job exposure. METHODS Male machinists (n = 26), car mechanics (n = 23), and house painters (n = 23) were studied. Whole day recordings of upper arm elevation were obtained for four consecutive working days, and(More)
AIMS To determine quantitative exposure-response relations between work with highly elevated arms and supraspinatus tendinitis, shoulder pain with disability, and shoulder pain without disability. METHODS A cross sectional study was conducted in a historical cohort of 1886 males from three occupational groups. Exposure measurements were performed for four(More)
BACKGROUND The physical and psychosocial work environment is expected to modify recovery from shoulder disorders, but knowledge is limited. METHODS In a follow up study of musculoskeletal disorders in industrial and service workers, 113 employees were identified with a history of shoulder pain combined with clinical signs of shoulder tendonitis. The(More)
OBJECTIVES Three previous randomized controlled trials found no overall difference in the effect of surgery compared with non-surgical treatment including exercise for patients with non-traumatic shoulder disorders. We assessed Danish temporal trends in the incidence of surgery for rotator cuff-related shoulder disorders, frozen shoulder, and osteoarthritis(More)
OBJECTIVES We undertook a register-based cohort study to evaluate exposure-response relations between cumulative occupational mechanical exposures, and risk of lateral and medial inguinal hernia repair. METHODS Among all men born in Denmark between 1938 and 1988, we established a cohort comprising those aged 18-65 years of age, who had at least 1 year of(More)
BACKGROUND When conducting large scale epidemiologic studies, it is a challenge to obtain quantitative exposure estimates, which do not rely on self-report where estimates may be influenced by symptoms and knowledge of disease status. In this study we developed a job exposure matrix (JEM) for use in population studies of the work-relatedness of hip and knee(More)
BACKGROUND Rotator cuff tendinopathy including tears is a cause of significant morbidity. The molecular pathogenesis of the disorder is largely unknown. This review aimed to present an overview of the literature on gene expression and protein composition in human rotator cuff tendinopathy and other tendinopathies, and to evaluate perspectives of(More)
Study Design A prospective cohort study nested in a randomized controlled trial. Objectives To determine and compare responsiveness and minimal clinically important change of the modified Constant score (CS) and the Oxford Shoulder Score (OSS). Background The OSS and the CS are commonly used to assess shoulder outcomes. However, few studies have evaluated(More)
OBJECTIVES This study aims to (i) evaluate relative risks, excess fraction of cases, and rate advancement periods for total hip replacement (THR) due to primary osteoarthritis in relation to lifelong cumulative physical workload and (2) describe temporal trends in the proportion employed in the most highly exposed industries from 1986-2006. METHODS In a(More)
OBJECTIVES This study examined the validity of a common belief in epidemiology with respect to work-related musculoskeletal disorders, that individual mechanical job exposure is better estimated from tasks performed in the job than from the mean exposure of the occupational group. METHODS Whole-day recordings of upper trapezius electromyography were(More)
