Propelling a manual wheelchair (MWC) is a strenuous task that causes upper limb musculoskeletal disorders (MSD) in a large proportion of MWC users. Although most studies on MWC propulsion biomechanics assume that MWC propulsion is a relatively symmetric task, recent literature suggests that this is the case only when the assessed outcome measures are averaged over long periods of time, and not over short periods (i.e., instantaneously). No method is currently available to assess instantaneous symmetry. In this work, we present the Instantaneous Symmetry Index (ISI), a new method that quantifies how a variable has been instantaneously asymmetric during a selected time period...

Lifting and holding upper and lower limbs during the "prep and drape" portion of certain orthopaedic procedures exert strong forces on the holder and may lead to musculoskeletal disorders. To address these challenges during upper extremity procedures, this article describes a hand-free elevation and traction technique of the upper limbs during preoperative skin preparation with the use of items readily available within the operating room (OR). This technique is particularly useful for heavy or fractured limbs that may impose a physical challenge to lift and maintain in a stable position...

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...

COMPARATIVE STUDY
Edda Maria Capodaglio
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...

REVIEW
Johannes L Harmse, Jacobus C Engelbrecht, Johan L Bekker
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...
