“…Regarding musculoskeletal symptoms, despite the different methods and criteria used, neck and upper limbs were also the most reported body areas, as in other studies (Colombini & Occhipinti, 2006;Eatough et al, 2012;Eerd et al, 2016;Gold et al, 2009;Kitis et al, 2009;Sundstrup et al, 2013b). Referring the intensity of musculoskeletal symptoms, in work context the majority of complaints intensity appear to be mild; our study points out higher values, being musculoskeletal pain over 4 in NPS considered as significant (Werner et al, 2005).…”

Assembly lines are related to health risks and work-related musculoskeletal disorders (WMSD), particularly of the neck and upper limbs (WULMSD). The assessment of perceived musculoskeletal symptoms is essential to WULMSD prevention, but studies in this field are lacking. A cross sectional survey on assembly line workers (n=270) was performed. The objective of this study was to analyze the frequency and distribution of upper limb musculoskeletal symptoms in assembly line workers. Participants were predominantly men, with ages between 30 and 40 years. Neck and upper limbs pain/discomfort were the most reported symptoms (35.9%), with intensity predominantly moderate or severe. General Health Status and past musculoskeletal injury were the variables more related to the existence of musculoskeletal symptoms; longer working life in the same company, as under 5 years, were related to higher intensity of symptoms. An early identification of musculoskeletal symptoms and health surveillance over time is of most importance to develop WRULMSD prevention measures.

“…The risks associated with repetitive movements of the upper limbs where evaluated using the OCRA checklist (Table 1) (Colombini and Occhipinti, 2006;Occhipinti et al, 2000) to assess the risk in 30 work activities, which included the majority of the workers in the meat processing plant. Videos of 10 task cycles were recorded for each worker during task performance, for subsequent analysis.…”

“…Slaughtering and meat processing work involves high loading intensities and cyclic repetitive muscle actions of the upper limbs, which may represent an elevated risk of work-related musculoskeletal disorders (Quandt et al, 2006;Lipscomb et al, 2008). According to Occupational Safety and Health Administration (OSHA) (2013) risk factors for musculoskeletal disorders (MSDs) in poultry plants are the repetition, forceful exertion, awkward and static postures, vibration, and cold temperatures In consideration to these risk factors, the OCRA checklist was developed to analyze the workers exposure to various risks of developing upper limb work-related musculoskeletal disorders (UL-WMSDs) (strength demand, repetitiveness, inappropriate posture and inadequate movements, lack of recovery periods, and others defined as "complementary") related to activities performed (Colombini and Occhipinti, 2006;Occhipinti et al, 2000). The checklist was based on a consensus document of a technical committee in musculoskeletal injuries of the International Ergonomics Association (IEA) (Colombini and Occhipinti, 2006;Occhipinti et al, 2000).…”

Brazil is the world's leading poultry meat exporter since 2004. The poultry slaughtering workers are exposed to risk factors for work-related upper limb musculoskeletal disorders, such as repetitiveness, high frequency of technical actions, forceful exertions, inadequate posture, insufficient time for recovery, use of tools and exposure to cold temperatures. The aim of this study was to evaluate the risks associated with the repetitive movements of upper limbs in different tasks performed in a poultry slaughterhouse. In the poultry slaughterhouse 1,200 workers slaughtered 100,000 chickens per day during two work shifts. Ten percent of the company's employees were evaluated during the execution of work tasks, using the OCRA Checklist method. Each worker was filmed for a period of 5 minutes. The Student t-test (SPSS 17.0) was used, adopting p≤ 0.05, in order to compare the risk variable between the sides of the body. The 30 work activities analyzed were from the following sectors: packing (n=12); cutting (n=11); evisceration (n=3); reception (n=2); chiller (n=1); and freezing tunnels (n=1). The average of occupational repetitive actions performed by poultry workers was 64.4±16.1 per minute, representing 9 points in the OCRA's scale (0 to 10 points scale). The average score of OCRA's checklist of all the workstations analyzed was 22.7±5.6 points (moderate risk). The Checklist scores for the right upper limbs (average 22.5 -moderate risk) were significantly higher (p = 0.033) than the left upper limbs (mean of 21.7 -moderate risk), representing a higher risk for the right side of the body. Considering the five risk categories proposed by the OCRA Method, 11 work tasks (37%) were considered high risk, and 19 (63%) presented moderate risk. It is concluded that the majority of the slaughterhouse workers were vulnerable to ergonomic hazards by repetitive movements and to a greater probability of developing upper limb work-related musculoskeletal disorders (>21.5% probability for high risk and 10.8 to 21.5% for moderate risk).

“…Poor consideration of ergonomics in design for assembly also impacts on worker health. Musculoskeletal disorders (MSDs) are far more prevalent in manufacturing than other sectors [10; 11] and the physical strain is exacerbated when tasks are performed in 12] and demand force and repetition [13]. Due to these costly impacts on product quality and human performance it is widely recognised that better consideration of ergonomics needs to be integrated into the design of products and processes to optimise human work and output [14; 15; 16].…”

Aircraft system installation is still largely a manual process due and relatively low production volumes. However, as the aircraft market increases, the need to investigate ways to reduce the burden on installers becomes more pressing. Whilst the production volumes are increasing it is still not cost effective to automate these processes, and effort therefore needs to be made to minimize the burden on the operators during the manual installation of aircraft systems. This paper presents an investigation into how design for assembly and maintainability principles can be applied to ease systems installation in aircraft wings. Ergonomic issues associated with the current systems installation process were high value wing assembly facility. A range of installation issues and ergonomics evaluated using the Rapid Upper Limb Assessment (RULA) analysis tool in CATIA. Design methods from design for assembly, maintainability and ergonomics were applied to investigate how the manual systems installation process could be improved for a simple design problem. The results are compared and discussed. LITERATURE REVIEWDesign for Assembly (DFA) has been widely studied and has been applied extensively in industry, particularly for mass production. Boothroyd, Dewhurst and Knight [1 "the design of the product for ease of assembly". DFA helps manufacturers to create "world class products with improved quality, lower cost, and with shorter design cycle" by helping them to "understand the costs of production from the earliest stages of the development while at the same time bringing a relentless focus to the part count" [2]. DFA provides a structured approach to assessing the ease of assembly for a product as a basis for redesign. Applying Design for Assembly Principles in Computer Aided Design Systems InstallationsHelen Lockett, Sarah Fletcher, and Nicolas Luquet ABSTRACTThe installation of essential systems into aircraft wings involves numerous labour-intensive processes. Many human operators are required to perform complex manual tasks over long periods of time in very challenging physical positions speed and quality of production but also, in the longer term, can cause costly human resource problems from operators' cumulative development of musculoskeletal injuries. These problems are exacerbated in areas of the wing which house multiple systems components because the volume of manual work and number of operators is higher but the available space is reduced. might redesign systems installations in the enclosed wing environment to better enable operator access and reduce production time.This paper describes a recent study that applied design for assembly and maintainability principles and CATIA v5 computer aided design software to identify small design changes for wing systems installation tasks. Results show positive impacts for ergonomics, production time and cost, and maintainability, whilst accounting for aircraft performance and machining capabilities.
