We identified factors protective of all-cause sickness absence (SA) among subjects with multisite musculoskeletal pain (MSP). The nationally representative source sample comprised 3420 actively working Finns aged 30-55 in year 2000 and alive at follow-up. Pain in 18 body locations was combined into four sites (neck, low back, upper limbs, lower limbs). The baseline prevalence of MSP (pain in ≥ 2 sites) was 32 %. Baseline data on sociodemographic factors, work ability, work, health, and lifestyle were gathered by questionnaire, interview and clinical examination and linked with national registers on all-cause SA (periods lasting ≥10 workdays) for 2002-2008...

Fatigue has been linked to deficits in production quality and productivity and, if of long duration, work-related musculoskeletal disorders. It may thus be a useful risk indicator and design and evaluation tool. However, there is limited information on the test-retest reliability, the sensitivity, and the effects of diurnal fluctuation on field usable fatigue measures. This study reports on an evaluation of 11 measurement tools and their 14 parameters. Eight measures were found to have test-retest ICC values greater than 0...

Many contemporary occupations are characterised by long periods of low loads. These lower force levels, which are relevant to the development of work-related musculoskeletal disorders, are usually not the focus of fatigue studies. In studies that did measure fatigue in light manual or precision work, within and between measurement responses were inconsistent. The aim of this study was to identify fatigue measures that were responsive at lower force levels (<10% MVC) over the course of an 8-h period. A complementary set of fatigue measures, reflecting both neuromuscular and cognitive mechanisms, was measured during a light precision micro-pipetting task performed by 11 participants...

The working posture is part of the risk factors for the development of muscle-skeletal disorders. Compared to postural problems of the trunk and upper limbs, those related to the lower limbs have been so far undervalued in the context of preventive medicine and ergonomics. The risk assessment tools for the lower limbs posture are inhomogeneous and incomplete. The classification of postures, the quantification of the risk, the correlation with organizational and individual aspects, and interventions for the prevention and management of the risk are aspects yet to be explored...

BACKGROUND: Farmers have an increased risk for musculoskeletal disorders (MSD) such as osteoarthritis of the hip, low back pain, and neck and upper limb complaints. The underlying mechanisms are not fully understood. Work-related exposures and inflammatory responses might be involved. Our objective was to identify plasma proteins that differentiated farmers with MSD from rural referents. METHODS: Plasma samples from 13 farmers with MSD and rural referents were included in the investigation...

OBJECTIVE: To investigate the exposure-response relationships between alternative frequency weightings of hand-transmitted vibration (HTV) and neck and upper limb musculoskeletal disorders (MSDs) in a cohort of HTV workers. METHODS: In a three-year longitudinal study, the occurrence of neck and upper limb MSDs was investigated in 249 HTV workers and 138 control men. In the HTV workers, MSDs were related to measures of daily vibration exposure expressed in terms of 8-h energy-equivalent frequency-weighted acceleration magnitude [A(8)]...

The poultry abattoir industry continues to grow and contribute significantly to the gross domestic product in many countries. The industry expects working shifts of eight to eleven hours, during which workers are exposed to occupational hazards which include physical hazards ranging from noise, vibration, exposure to cold and ergonomic stress from manual, repetitive tasks that require force. A PubMed, Medline and Science Direct online database search, using specific keywords was conducted and the results confirmed that physical and ergonomic hazards impact on abattoir processing workers health, with harm not only to workers' health but also as an economic burden due to the loss of their livelihoods and the need for treatment and compensation in the industry...

Beekeepers are at particular risk of developing work-related musculoskeletal disorders, but many of the studies lack detailed exposure assessment. To evaluate the biomechanical overload exposure in a specific farming activity, a multitasking model has been developed through the characterization of 37 basic operational tasks typical of the beekeeping activity. The Occupational Repetitive Actions (OCRA) Checklist and the National Institute for Occupational Safety and Health (NIOSH) Lifting Index methodologies have been applied to these elementary tasks to evaluate the exposure, and the resulting risk indices have been time-weighted averaged...

BACKGROUND: Work-related musculoskeletal disorders (WMSD) is the most expensive form of work disability. Female sex has been considered as an individual risk factor for the development of WMSD, specifically in the neck and shoulder region. One of the factors that might contribute to the higher injury rate in women is possible differences in neuromuscular control. Accordingly the purpose of this study was to estimate the effect of sex on shoulder joint position sense acuity (as a part of shoulder neuromuscular control) in healthy individuals...

BACKGROUND: Musculoskeletal disorders are one of the most common work-related diseases. Frequently this association is thought to have a temporal cause-effect relation. The absence of accessible diagnostic criteria and ethological cause-effect demonstration are probably important reasons for the lack of good evidence data on these pathologies. OBJECTIVE: For these reasons, the authors aim to present a systematic review on prevalence and incidence of the upper limb WRMSD...

Nowadays the process of workstation design tends to include assessment steps in a virtual environment (VE) to evaluate the ergonomic features. These approaches are cost-effective and convenient since working directly on the digital mock-up in a VE is preferable to constructing a real physical mock-up in a real environment (RE). This study aimed at understanding the ability of a VR-based assembly tasks simulator to evaluate physical risk factors in ergonomics. Sixteen subjects performed simplified assembly tasks in RE and VE...
