Comorbid symptoms of depression and musculoskeletal pain and risk of long term sickness absence
Background: Symptoms of depression and musculoskeletal pain have both been found to be associated with increased risk of long term sickness absence (LTSA). The comorbidity between depression and pain i.e. simultaneous presence of both symptoms, is well established in the literature. The aim for the current investigation was to investigate whether the presence of comorbid pain influences the associations between depressive symptoms and LTSA or if the presence of comorbid depressive symptoms influences associations between musculoskeletal pain and LTSA. Methods: A sample of 6572 Danish female health...
The influence of external load configuration on trunk biomechanics and spinal loading during sudden loading
Sudden loading is a major risk factor for work-related lower back injuries among occupations involving manual material handling (MMH). The current study explored the effects of external weight configuration on trunk biomechanics and trunk rotational stiffness in the sagittal plane during sudden loading. Fifteen asymptomatic volunteers experienced sudden loadings using the same magnitude of weight (9 kg) with two different configurations (medially- or laterally-distributed) at three levels of height (low, middle and high). Results of this study showed that the medially distributed weight...
Occupational biomechanical risk factors for surgically treated ulnar nerve entrapment in a prospective study of male construction workers
Evidence was provided for forceful hand-grip work, with and without vibration, as a risk factor for ulnar nerve entrapment (UNE) surgery in a large cohort of Swedish construction workers. Several individual biomechanical factors comprising such work were associated with increased risk of UNE, including: increased grip force, upper extremity load, frequency of hand-held tool use, and hand arm vibration.

Frequent Exertion and Frequent Standing at Work, by Industry and Occupation Group - United States, 2015
Repeated exposure to occupational ergonomic hazards, such as frequent exertion (repetitive bending or twisting) and frequent standing, can lead to injuries, most commonly musculoskeletal disorders. Work-related musculoskeletal disorders have been estimated to cost the United States approximately $2.6 billion in annual direct and indirect costs. A recent literature review provided evidence that prolonged standing at work also leads to adverse health outcomes, such as back pain, physical fatigue, and muscle pain. To determine which industry and occupation groups currently have the highest prevalence...

Paramedics' working strategies while loading a stretcher into an ambulance
For paramedics, loading a stretcher into an ambulance is an activity with a high risk of back injury and accidents. The objective of this study was to document strategies paramedics use at work while loading a powered stretcher into an ambulance. A total of 249 stretcher loading operations performed by 58 paramedics, and 51 semistructured post-intervention interviews were analyzed. Almost three quarters of loading operations required additional actions (e.g., raising the shoulders and additional lifting) to insert the stretcher into the cot fastener system in the ambulance. Some strategies that...
Perceived affordances and postures for lifting in child care
Childcare work appears to be full of the physical and mental risk factors frequently associated with chronic exertion leading to injury of the musculoskeletal system. The purpose of this study was to examine the affordances and mechanics for lifting a child, and to associate those mechanics with physical demands reports provided by experienced childcare workers. Participants perceived a smaller safe reaching distance to a child compared to a conventional handling target, despite the identical load and similar load distribution. This difference may reflect the influence of coupling (suitcase had...
