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.

Abstract: Work related musculoskeletal disorders are seen as an indicating parameter of occupational stress among the women workers engaged in tea leaf plucking operation. The hand plucking (no mechanized plucking is practiced in Assam) being a highly repetitive task requires forceful exertions to reach to the distant periphery of the tea bushes and mechanical compression (pressing against hard surfaces). Specifically it aggravates with awkward positions adopted. The current research addresses to minimize the risk factors associated with CTDs and to ascertain the role of ergonomic design development in improving the situation. Women workforce engaged in tea industry in Assam suffer from…back, shoulder, arm and finger pains. Workers perform the activity for 440 minutes in the entire shift with one hour lunch break in between in the garden itself. An ergonomic investigation aiming at studying the strain index of plucking operation in tea industry was conducted. While performing the operation workers were found to assume unnatural posture which is static as well as highly dynamic with a load (tea leaf collecting basket up to weight of 30 kg when filled with plucked leaves) at back. With gradual increment of load and pain though the load is released intermittently the strain level found to remain at a high level. The total QEC scores found for plucking activity was 110 out of 138. To improve the situation and to reduce the work related upper limb disorder (WRULD) an ergonomically designed basket was conceived and trial results showed improvements. The newly designed plucking basket fits the back curvature of the workers well, which keeps the basket in place unlike the existing round basket. The new basket is light in weight having more leaf capacity. Significant reduction in energy expenditure and MSDs suffered was observed while using improved basket over existing basket.

Abstract: Conventional and improved methods of aonla pricking were evaluated ergonomically on an experiment conducted for 20 minute with women workers. The working heart rate, energy expenditure rate, total cardiac cost of work and physiological cost of work with conventional tools varied from 93-102 beats.min-1 , 6-7.5 kJ.min-1 , 285-470 beats, 14 -23 beats.min-1 while with machine varied from 96-105 beats.min-1 , 6.5-8 kJ.min-1 , 336-540 beats, 16-27 beats.min-1 respectively. OWAS score for conventional method was 2 indicating corrective measures in near future while with machine was 1 indicating no corrective measures. Result of Nordic Musculoskeletal Questionnaire revealed…that subjects complaint of pain in back, neck, right shoulder and right hand due to unnatural body posture and repetitive movement with hand tool. Moreover pricking was carried out in improper lighting conditions (200-300 lux) resulting into finger injuries from sharp edges of hand tool, whereas with machine no such problems were observed. Output with machine increased thrice than hand pricking in a given time. Machine was found useful in terms of saving time, increased productivity, enhanced safety and comfort as involved improved posture, was easy to handle and operate, thus increasing efficiency of the worker leading to better quality of life.

Abstract: This article reports the experience of the design team of the Laboratory The Imaginary in the process of developing an electric potter’s lathe which respects the biomechanics of the body, helps to development the task, maintains the archetype of traditional equipment, and improves the mechanical efficiency of the power transmission system. The design method used was based on the axes of research, analysis, development and monitoring, and focused on the product and with partners: the artisans and engineering and production teams. The main results point to ergonomic improvements in the biomechanical and dimensional aspects, and a decrease in the risk…of accidents and occupational diseases. The experience of this case also highlights the gains arising from the relationship between design, engineering and users (artisans) in developing products with a design that can be easily replicated for other communities of potters in the state. This and other actions are part of the outlook of the Laboratory the Imaginary which in partnership with local authorities, wishes to see the craft activities continue and to give value to the culture of the city.

Abstract: The purpose of this study is to reflect on safety requirements for children’s clothing, based on the standardization proposed by the ABNT (Technical Standardization Brazilian Association). Bibliographic research and case studies were considered on writing this work. We also discuss the importance of adding other safety requirements to the current standardization, as well as the increasing of the actual age range specified by the ABNT, following the children’s clothing safety standardizations in Portugal and the United States, also stated here.
Abstract: A company making women’s clothing, located in Belo Horizonte, Minas Gerais was studied in its ergonomic aspects with regard to the layout. With this study it was possible to establish the best positioning of machines and jobs of employees. The analysis criteria used were: frequency of use, functional grouping, sequence of use, flow and intensity of preferred connections. An ideal arrangement in the workplace provides improved manufacturing quality and employee performance and consequently higher production yields.

Abstract: Mattress, as a sleep platform, its types and physical properties has an important effect on sleep quality and rest efficiency. In this paper, by subjective evaluations, analysis of sleeping behaviors and tests of depth of sleep, the relationship between characteristics of the bedding materials, the structure of mattress, sleep quality and sleep behaviors were studied. The results showed that: (1) Characteristics of the bedding materials and structure of spring mattress had a remarkable effect on sleep behaviors and sleep quality. An optimum combination of the bedding materials, the structure of mattress and its core could improve the overall comfort of…mattress, thereby improving the depth of sleep and sleep quality. (2)Sleep behaviors had a close relationship with sleeping postures and sleep habits. The characteristics of sleep behaviors vary from person to person.

Abstract: Proper body support plays an import role in the recuperation of our body during sleep. Therefore, this study uses an automatically adapting bedding system that optimises spinal alignment throughout the night by altering the stiffness of eight comfort zones. The aim is to investigate the influence of such a dynamic sleep environment on objective and subjective sleep parameters. The bedding system contains 165 sensors that measure mattress indentation. It also includes eight actuators that control the comfort zones. Based on the measured mattress indentation, body movements and posture changes are detected. Control of spinal alignment is established by fitting personalized…human models in the measured indentation. A total of 11 normal sleepers participated in this study. Sleep experiments were performed in a sleep laboratory where subjects slept three nights: a first night for adaptation, a reference night and an active support night (in counterbalanced order). Polysomnographic measurements were recorded during the nights, combined with questionnaires aiming at assessing subjective information. Subjective information on sleep quality, daytime quality and perceived number of awakenings shows significant improvements during the active support (ACS) night. Objective results showed a trend towards increased slow wave sleep. On the other hand, it was noticed that % N1-sleep was significantly increased during ACS night, while % N2-sleep was significantly decreased. No prolonged N1 periods were found during or immediately after steering.

Abstract: This project presents an analysis of the ergonomic conditions of three types of mattress and three types of pillow. The products are manufactured by a Colombian company which specializes in flexible polyurethane foam and other products designed for rest and relaxation. The project was developed through the University – Industry relationship: a strategic partnership based on the knowledge and strengths of each component. The conceptual theories that underpin the Ergonomics Research Division of the Design Studies Research Group (GED) provided the methodological approach for the project: the characteristics, the requirements and the relationships that are established between the components that…constitute the User – Product – Context system (basic principles of the Ergonomics – Design relationship). An important factor in the project was the conception and measurement of comfort. Comfort can be measured on an objective level (quantitative measurement), and on a subjective level (a user’s particular perceptions and tastes). What constitutes ‘comfort’ can vary from person to person, thus making the identification of criteria for the standardization of consumer products problematic. This project enabled design recommendations to be made to the Company vis-à-vis future proposals for mattress and pillow products. This experience of applied research was carried out by professors and students from the Faculty of Industrial Design at the UPB in Medellín, Colombia.

Abstract: Study reported a pillow with a uniform height was not suitable for sleeping in supine and lateral positions. The study aims to determine the pillow dimensions for fitting supine and lateral positions for Taiwanese. Ten females and ten males subjects with a mean age of 21.9 years (SD= 1.07 years) participated in the study. Body dimensions of head, neck and shoulder in crown and sagittal planes were measured with the Martins’ anthropometer and a curve measurer to determine the pillow’s sizes. The results showed that the basic form of pillow for both genders is a U form from the front…view. The middle area of the pillow is for supine position and the both side areas are for lateral positions. The base of pillow is a rectangle from the top view. The pillow is designed with a width of 75 and 70 cm for male and female, and a depth of 40 and 35 cm for male and female. The height in middle area and both side are 4 and 14 cm for male, and 2 and 12 cm for female. A neck rest with a height of 1.5 cm was proposed for neck support.

Abstract: This study is guided by the principle that there is no technology detached from an ideology. This ideology appears in the interfaces conditioning the relationship between people and digital artifacts. This article adopts as theoretical reference the User-Centered Design (UCD). Under the UCD principles it is presented a key to understand how technology is a vehicle of ideological content that affects the design practices.
