WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal's subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
WORK occasionally publishes thematic issues, but in general, issues cover a wide range of topics such as ergonomic considerations with children, youth and students, the challenges facing an aging workforce, workplace violence, injury management, performing artists, ergonomic product evaluations, and the awareness of the political, cultural, and environmental determinants of health related to work.
Dr. Karen Jacobs, the founding editor, and her editorial board especially encourage the publication of research studies, clinical practice, case study reports, as well as personal narratives and critical reflections of lived work experiences (autoethnographic/autobiographic scholarship),
Sounding Board commentaries and
Speaking of Research articles which provide the foundation for better understanding research to facilitate knowledge dissemination.
Narrative Reflections on Occupational Transitions, a new column, is for persons who have successfully transitioned into, between, or out of occupations to tell their stories in a narrative form. With an internationally renowned editorial board,
WORK maintains high standards in the evaluation and publication of manuscripts. All manuscripts are reviewed expeditiously and published in a timely manner.
WORK prides itself on being an author-friendly journal.

Abstract: The study aimed to evaluate a work method intervention in a smoke detector assembly line. High hand gripping forces and extreme wrist postures were found in the smoke detector assembly line at UTC Fire & Security Company in Maine. A fixture was introduced to replace the old assembly method. Electromyography (EMG) and electrogoniometry were used to measure the workers' hand gripping force and wrist motions with both the old and new assembly methods. Results show both hand gripping forces and wrist postures improved significantly with the new method.

Abstract: This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handling of boxes, identified by the revised NIOSH equation as posing an increased risk for lifting-related low back pain, were totally eliminated, and the employees responsible for moving boxes from the end of the assembly line to pallets on…the ground were given more control over their jobs, and these jobs were also enriched with a new, less heavy task. These results demonstrate that participatory ergonomic interventions are a viable and effective strategy to reduce the exposure to work-related physical and psychosocial risk factors for low back pain.

Abstract: Due to the many constraints that small businesses (SBs) face in meeting legislative requirements, occupational health and safety (OHS) regulatory authorities and other OSH actors have developed programmes which can reach out to SBs and motivate and assist them in improving the work environment. A number of conceptual models help to enhance our understanding of OHS interventions in SBs and their effectiveness. However, they have mainly been evaluated on output rather than the process relating to the change theory underlying the intervention, and hence have seldom been rigorously evaluated. Thus little is known about how particular features of SBs can…be taken into account when designing and implementing national programmes. This paper shows how realist analysis and programme theory may be used as a framework for evaluating, developing and improving national intervention programmes for the improvement of the work environment and reducing injuries in SBs. It illustrates this for a specific New Zealand intervention: the Workplace Safety Discount scheme and its implementation in the agriculture sector. In practice, realist analysis should be performed during the planning, implementation and management stages so that ongoing findings can be fed back to the participant social actors to help them make appropriate changes to enhance the likelihood of success.

Abstract: Musculoskeletal disorders (MSD's) are a constellation of disorders. There is no single tool available which guides the clinicians to predict the severity, intervention and recovery period of the patients who is suffering from different musculoskeletal disorder. In this paper authors tried to categorize the severity of the musculoskeletal discomfort and the prognosis of the recovery period. The questionnaire was formulated using different epidemiological risk factor of the development of MSD and the effect of MSD on physical and psychosocial factors. The questionnaire contains 13 questions which include seven direct (rating was 0, 2, 4, 6, 8 and 10) and six…indirect (rating was 0, 1, 2, 3, 4 and 5) questions. Results revealed a significant correlation with the prognosis of recovery and the actual recovery period (r= 0.80). It also showed a significant correlation between the total severity score and the actual recovery (r=0.82) period. Depending on the prognosis of the recovery the severity score was segregated in four categories as mild, moderate, severe and complicated. Due to small sample size the prognosis of recovery for higher severity score could not be plotted.

Abstract: $\underline{Objective}$: Investigate effects of interactions between biomechanical, psychosocial and individual risk factors on the body's immune inflammatory responses. $\underline{Background}$: Current theories for low back pain causation do not fully account for the body’s response to tissue loading and tissue trauma. $\underline{Methods}$: Two groups possessing a preference for the sensor or intuitor personality trait performed repetitive lifting combined with high or low mental workload on separate occasions. Spinal loading was assessed using an EMG-assisted subject-specific biomechanical model and immune markers were collected before and after exposure. $\underline{Results}$: Mental workload was associated with a small decrease in AP shear. Both conditions were…characterized by a regulated time-dependent immune response making use of markers of inflammation, tissue trauma and muscle damage. Intuitors’ creatine kinase levels were increased following low mental workload compared to that observed in Sensors with the opposite trend occurring for high mental workload. $\underline{Conclusions}$: A temporally regulated immune response to lifting combined with mental workload exists. This response is influenced by personality and mental workload.

Abstract: Employees differ in their apperception of open plan offices. Despite this, individual differences have been sparsely treated in the literature discussing effects of office design. The aim of the present study was to investigate how stimulus screening, working memory, and attention interrelate and affect important factors in the work environment. The study utilized a cross sectional design. Participants (N=35) were recruited among employees in four organizations. Working memory was assessed bye means of the Operation –Word Span Task (OSPAN) while attention was measured by the d2 test of attention. Dependent variables were job stress, job involvement, organizational commitment, and need…for recovery. The results showed a main affect of stimulus screening on need for recovery and one subscale of organizational commitment. A main effect was also found for fluctuation rate across trials, a sub measure of attention, on need for recovery. The results revealed no indication of any mediator or moderator effects of either working memory or attention, on stimulus screening, for any of the dependent variables. Thus, the effect of stimulus screening seems not to be explained through individual differences in cognitive processes.

Abstract: In order to accommodate the desired percentage of the target users of a product, decisions must be made to ensure that the design satisfies performance requirements such as user safety, comfort, and ease of use. The marketing concept of “utility theory” is one approach to quantifying the effects of design decisions. It is leveraged in this study to develop a design evaluation approach that considers: a) factors that may be either design-related (design specifications) or user-related (relevant body dimensions) and b) the raw material investment in the design. Based on data collected during a usage behavior study involving doorways of…numerous sizes, a conditional logit model was developed to predict the utility of a doorway as a function of its size and the user's stature and shoulder breadth. Next, an eco-design parameter was incorporated into the model as a penalty based on raw material usage. This approach was found to be useful in studying frequently encountered tradeoffs in decisions that could potentially increase product sustainability but could also reduce the utility of the product to the user.

Abstract: A river container terminal concentrates many of the constraints encountered by different transport modes (road, rail, and waterways) involved in the delivery of merchandises. For the operators in charge of handling operations during peaks of activity, this configuration yields significant difficulties when performing planning, scheduling and dispatching tasks. The research conducted at the second French river port unravels the mechanisms involved in the management of these dynamic environments. Following a series of interviews and preliminary observations, we conducted systematic observations of the foremen's work. These middle managers are located at the juncture of management and production. The data was…completed with additional interviews for the purpose of cross-checking the validity of the results. The results point to the extreme variability of situations and the high exposure to uncertainty inherent in the transport business. Beyond the tasks of loading and unloading, completed by checks and other operations, container handling consists in trying to absorb, or at least reduce the effects of the combination of constraints in the delivery of merchandises and to ensure greater flow of traffic in the network node. The results also highlight organizational compromises through the permanent adjustment of the means of production in the scheduling and dispatching activities.

Abstract: In the workplace there are risk factors that can overwhelm the health of the worker causing physical and psychological disorders. Among these disorders, is occupational stress. Thus, this research proposes to measure the mental workload of job stress from the identification of demand, control and social support. It is an observational cross-sectional epidemiological character, performed with the Rectory office workers at the State University of West Paraná (Unioeste). Data collection was due to the application of the “Job Stress Scale” (JSS) and in its reduced version adapted to Portuguese. The survey sample consisted of 44 individuals. Statistical analysis was correlated…inversely with medium intensity (r = − 0.404) between age and social support. For males was found between control and age (r = 0.603). According to the data obtained, we conclude that most workers are exposed to passive work, leading to loss of skills or disinterest in the job. This study highlights the importance of research in the area and the need for new actions that change the conditions of stress at work.
