“…A drawback in the design process is the mismatch between user requirements to reduce workplace risk factors for MSDs and what is ultimately produced [11,12].

BACKGROUND: Work-related Musculoskeletal Disorders (MSDs) affect the well-being of workers. Unfortunately, user requirements for design to reduce workplace risk factors for MSDs are not always effectively communicated to designers creating a mismatch between the user requirements and what is ultimately produced. OBJECTIVE:To understand the views of practitioners of design and ergonomics regarding tools for participatory design and features they would like to see in such tools. METHODS:An online questionnaire survey was conducted with a cohort of practitioners of ergonomics and design (n=32). In-depth interviews were then conducted with a subset of these practitioners (n=8). To facilitate discussion, a prototype integrated design tool was developed and demonstrated to practitioners using a verbalized walkthrough approach. RESULTS:According to the results of the questionnaire survey, the majority (70%) believed an integrated approach to participatory design would help reduce work-related MSDs and suggested ways to achieve this, for example, through sharing design information. The interviews showed the majority (n=7) valued being provided with guidance on design activities and ways to manage and present information. CONCLUSION:It is believed that an integrated approach to design in order to help reduce work-related MSDs is highly important and a provision to evaluate design solutions would be desirable for practitioners of design and ergonomics.Keywords: design process; participatory design; design methods IntroductionWork-related musculoskeletal disorders (MSDs) affect the health and well-being of workers and can hinder growth in the industrial sector causing staggering expense [1]. Attempts have been made to reduce MSDs in the working population, for example, intervention programs [2-5], standards [6] and guidelines [7,8] have been developed to try to eliminate workplace risk factors, but they are still commonplace. Research suggests that more intervention approaches are required and that methods currently being used to reduce the risk of MSDs among workers could be improved [9,10]. Adherence to ergonomics in design together with a full assessment of work systems would help curb work-related MSDs [1].A drawback in the design process is the mismatch between user requirements to reduce workplace risk factors for MSDs and what is ultimately produced [11,12]. Stakeholders in the design process include users that directly interact with equipment and processes and practitioners such as engineers, designers and others such as ergonomists, occupational health professionals and health and safety personnel that may be involved in the design process and influence design decisions. However, the involvement of such professionals varies [13] and 2 user focused design requirements to reduce workplace risk factors for MSDs are not always effectively and efficiently conveyed preventing appropriate solutions being incorporated in the next generation of designs. Thus, a mechanism to fill this void between the users and the ...

“…Others have indicated that changes in checkout workstation design, without modifying the methods of scanning, lifting and transferring objects, will only partially reduce the risk of injury 8,13 . In contrast, although the trunk is the most affected segment among checkout operators (60.0 -77.0% of incidence) 4,13 , no studies have performed a biomechanical analysis of the trunk to observe whether changes in checkout workstation design would help to reduce the occupational hazards of these operators.…”

“…The main risk factor associated with the development of cumulative trauma disorders is reported to be the prolonged exposure to repetitive bending/twisting movements at work 3 . Among several cumulative trauma disorders, back problems have been reported as the most frequent symptom among supermarket checkout operators 2,4,5 and may be associated with the large movements performed during the workday 6 and to ergonomic factors such as workstation design 7,8,9 .…”

Objectives: This study analyzed the effect of a standard and a modified checkout workstation during a simulated task on trunk postures of a supermarket checkout operator. Methods: Eight participants performed a task involving grasping, scanning and depositing products, while 3D images of the trunk were collected. Results: A number of kinematic changes were observed in trunk posture. A greater anterior flexion (3.0±1.2 o ) and lateral bending during grasping (7.1±1.4 o ) were found in the standard checkout workstation when compared to the modified model (p<0.05). Other variables did not show significant differences (p>0.05). Discussion: The modified checkout workstation provided less lateral bending of the trunk to grasp products (8.1 o ± 2.8; p<0.05), which was considered an advantage with respect to the standard model. Changes in the sagittal and transversal planes were not observed (p>0.05), irrespective of the checkout workstations (p>0.05). The modified checkout workstation successfully reduced risk of injury in some aspects, particularly the problems associated with lateral bending of the trunk. Other studies are required to test whether such potential benefits are obtained on a daily basis. Conclusions: Supermarket checkout operators may be at high risk of occupational injury due to different workstation demands.Modifications to checkout workstation design are an attractive possibility to reduce postural stress and fatigue in checkout operators.Longitudinal studies are required to test whether changes observed in the present study are sustained in the long term.Key words: supermarket checkout operators; supermarket checkout workstation; checkout workstation design; posture. ResumoObjetivos: Analisar o efeito de um modelo padrão e de um modificado de checkout durante uma tarefa simulada de um operador de caixa de supermercado. Métodos: Oito participantes desempenharam uma tarefa envolvendo apanhar, ler e depositar produtos, enquanto imagens 3D do tronco foram coletadas. Resultados: Um número de mudanças cinemáticas foram observadas na postura do tronco. Uma maior flexão anterior (3.0±1.2 o ) e uma inclinação lateral durante o apanhar (7.1±1.4 o ) foram encontradas no checkout padrão quando comparadas ao modelo modificado (p<0.05). Outras variáveis não apresentaram mudanças significativas (p>0.05).Discussão: O checkout modificado causou menor inclinação lateral do tronco para apanhar produtos (8.1 o ± 2.8; p<0.05), o que foi considerado como uma vantagem em relação ao modelo padrão. Mudanças nos planos sagital transverso não foram observadas (p>0.05), independente do modelo do checkout (p>0.05). O modelo modificado se mostrou eficaz paras prover reduções de risco de lesão em alguns aspectos. Especificamente, problemas associados com as inclinações laterais do tronco podem ser reduzidos quando o checkout modificado é empregado. Outros estudos são necessários para testar se tais benefícios potenciais são obtidos em uso de base diária. Conclusões: Operadores de supermercado podem ter elevado risco de le...

Abstract. This paper provides an overview of the various methods that have been developed for the assessment of risk factors for upper limb disorders among cashiers in grocery retail industries. This paper is essential as upper limb disorders have been known as one of the prime cause of work-related disability in various countries. The methods used for the assessment were the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, the Assessment of Repetitive Tasks (ART), the Job Strain Index (JSI) and the Occupational Repetitive Actions (OCRA) Checklist. DASH questionnaire is a structured interview in determining the prevalence of the upper limb disorders, while ART, the JSI and OCRA Checklist act as a direct observation in examining the involvement of risk factors. Basically, these tools dealt with the measurements of symptoms, posture observation, and workplace risk assessment, as they are the most relevant tools for assessing the risk factors faced by the workers in grocery industries. The use of these tools assessed the risk factors and consequently reduces the risk of injuries among the workers.
