Lind CM. A Rapid Review on the Effectiveness and Use of Wearable Biofeedback Motion Capture Systems in Ergonomics to Mitigate Adverse Postures and Movements of the Upper Body. SENSORS (BASEL, SWITZERLAND) 2024; 24:3345. [PMID: 38894134 PMCID: PMC11175029 DOI: 10.3390/s24113345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 05/16/2024] [Accepted: 05/19/2024] [Indexed: 06/21/2024]
Abstract
Work-related diseases and disorders remain a significant global health concern, necessitating multifaceted measures for mitigation. One potential measure is work technique training utilizing augmented feedback through wearable motion capture systems. However, there exists a research gap regarding its current effectiveness in both real work environments and controlled settings, as well as its ability to reduce postural exposure and retention effects over short, medium, and long durations. A rapid review was conducted, utilizing two databases and three previous literature reviews to identify relevant studies published within the last twenty years, including recent literature up to the end of 2023. Sixteen studies met the inclusion criteria, of which 14 were of high or moderate quality. These studies were summarized descriptively, and the strength of evidence was assessed. Among the included studies, six were rated as high quality, while eight were considered moderate quality. Notably, the reporting of participation rates, blinding of assessors, and a-priori power calculations were infrequently performed. Four studies were conducted in real work environments, while ten were conducted in controlled settings. Vibration feedback was the most common feedback type utilized (n = 9), followed by auditory (n = 7) and visual feedback (n = 1). All studies employed corrective feedback initiated by the system. In controlled environments, evidence regarding the effectiveness of augmented feedback from wearable motion capture systems to reduce postural exposure ranged from strong evidence to no evidence, depending on the time elapsed after feedback administration. Conversely, for studies conducted in real work environments, the evidence ranged from very limited evidence to no evidence. Future reach needs are identified and discussed.

Are Organizational Interventions Effective in Protecting Healthcare Worker Mental Health during Epidemics/Pandemics? A Systematic Literature Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159653. [PMID: 35955009 PMCID: PMC9368524 DOI: 10.3390/ijerph19159653] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 07/28/2022] [Accepted: 08/03/2022] [Indexed: 05/09/2023]
Abstract
It is unclear how to effectively protect healthcare workers' mental health during infectious disease epidemics. Targeting the occupational determinants of stress may hold more promise than individual stress management, which has received more focus. Through a systematic review of the 2000-2021 English- and French-language scientific literature, we evaluated the effectiveness of organizational and psychosocial work environment interventions to protect healthcare workers' mental health in an epidemic/pandemic context. Evidence from medium- and high-quality studies was synthesized using GRADE. Among 1604 unique search results, 41 studies were deemed relevant, yielding 34 low-quality and seven medium-quality studies. The latter reported on promising multi-component prevention programs that combined staffing adjustments, work shift arrangements, enhanced infection prevention and control, recognition of workers' efforts, psychological and/or logistic support during lockdowns (e.g., accommodation). Our confidence in the effectiveness of reviewed interventions is low to very low, however, owing to methodological limitations. We highlight gaps in the reporting of intervention process and context elements and discuss theory and implementation failure as possible explanations for results. We conclude by urging authors of future studies to include and document detailed risk assessments of the work environment, involve workers in solution design and implementation and consider how this process can be adapted during an emergency.

Abstract
AIMS To explore how a support model (Stamina) targeting the systematic work environment management was experienced, provided and implemented in Swedish municipalities. METHODS A mixed method approach was applied, including material from interviews and questionnaire. The questionnaire was answered by 123 persons (67.5%), and 18 participants were interviewed twice during a one year period. Data were analysed using descriptive statistics and qualitative content analysis. RESULTS The participants followed the structure of the Stamina model in their practical work. Still, there was variation in the practical provision of the model. The implementation was supported by their organizations and was influenced by various actors. Creating commitment was an essential part to facilitate implementation. CONCLUSION To promote implementation of the Stamina model, there is a need to create commitment among stakeholders that will participate in the implementation.

Abstract
It can be difficult to select from available safety preventative measures, especially where there is limited evidence of effectiveness in different contexts. This paper describes application of a method to identify and evaluate wide-ranging preventative measures for rail suicide and trespass fatalities. Evidence from literature and industry sources was collated and reviewed in a two stage process to achieve consensus among experts on the likely effects of the measures and factors influencing their implementation. Multiple evaluation criteria were used to examine the measures from different perspectives. Fencing, awareness campaigns and different types of organisational initiatives were recommended for further testing. This is the first time evidence has been collected internationally across such a range of preventative measures. Commentary is provided on using this type of approach to select safety measures from a pool of prevention options, including how re-framing the scope of the exercise could identify alternative options for prevention. Practitioner summary: The findings give insight to how different measures work in different ways and how industry can consider this in strategic initiatives. The method could be used in future studies with different frames of reference (e.g. different timescales, level of ambition and safety context e.g. railway crossings or highway fatalities). Abbreviation: RESTRAIL: REduction of Suicides and Trespasses on RAILway property.

Abstract
BACKGROUND The working environment should be a naturally integrated part of business development. Provisions are in place that address the employer's obligations to investigate, carry out and follow up activities in such a way that ill health and accidents at work are prevented and a satisfactory working environment is achieved. Still, there are organizations that not properly perform systematic work environment management. In order to improve adherence, interventions and models focused on these issues need to be easy to understand and provide rapid feedback of results in order to be implemented. The Stamina model has recently been implemented in Sweden. The model is a participatory organizational systematic model facilitating the work environment, productivity and quality. It is a support model that provides structured and recurrent feedback in the systematic work environment management. The aim of the present paper is to thoroughly describe the Stamina model and the studies that are designed to investigate the effect, to increase the understanding of how and why the model was or was not effective, and to identify factors that facilitate implementation. METHODS The paper presents a project consisting of two related evaluation parts. Part one is an effect evaluation with an active group applying the Stamina model and a control group. This part investigate effects on proxy outcomes that are relevant for health and productivity. Part two is a process evaluation with a qualitative design. This part will be based on semi-structured interviews with various stakeholders, such as employees, first line managers, project managers, facilitators and representatives from the management group, in the organizations. DISCUSSION Many interventions found to be effective in research projects fail to translate into meaningful outcomes across multiple contexts. In this project a participatory approach will be adopted, including the possibility to modify the model according to organizational needs and preconditions. Valuable knowledge regarding the design and implementation of the model will be generated in order to develop a model that is suitable and sustainable in organizations.

Abstract
The Stage of Change (SOC) approach has been proposed as a method to improve the implementation of ergonomics advice. However, despite evidence for its efficacy there is little evidence to suggest it has been adopted by ergonomics consultants. This paper investigates barriers and facilitators to the implementation, monitoring and effectiveness of ergonomics advice and the adoption of the SOC approach in a series of focus groups and a subsequent survey of members of the Human Factors Societies of Australia and New Zealand. A proposed SOC assessment tool developed for use by ergonomics practitioners is presented. Findings from this study suggest the limited application of a SOC based approach to work-related musculoskeletal injury prevention by ergonomics practitioners is due to the absence of a suitable tool in the ergonomists' repertoire, the need for training in this approach, and their limited access to relevant research findings. The final translation of the SOC assessment tool into professional ergonomics practice will require accessible demonstration of its real-world usability to practitioners and the training of ergonomics practitioners in its application.

Abstract
Knife sharpness is imperative in meat cutting. The aim of this study was to compare the impact of knife blade steel quality with meat cutters' individual ability to maintain the cutting edge sharp in an industrial production setting. Twelve meat cutters in two different companies using three different knives during normal production were studied in this quasi-experimental study. Methods included were measuring knife cutting force before and after knife use, time knives were used, ratings of sharpness and discomfort and interviews. Results showed that the meat cutters' skill of maintaining sharpness during work had a much larger effect on knife sharpness during work than the knife steel differences. The ability was also related to feelings of discomfort and to physical exertion. It was found that meat cutters using more knives were more likely to suffer from discomfort in the upper limbs, which is a risk for developing MSD.

Abstract
Work related musculoskeletal disorders remain an intractable OHS problem. In 2002, Haslam proposed applying the stage of change model to target ergonomics interventions and other health and safety prevention activities. The stage of change model proposes that taking into account an individual's readiness for change in developing intervention strategies is likely to improve uptake and success. This paper revisits Haslam's proposal in the context of interventions to reduce musculoskeletal disorders. Effective MSD interventions require a systematic approach and need to take into account a combination of measures. Research evidence suggests that in practice, those charged with the management of MSDs are not consistently adopting such an approach. Consequently, intervention development may not represent contemporary best practice. We propose a potential method of addressing this gap is the stage of change model, and use a case study to illustrate this argument in tailoring intervention development for managing MSDs.

Abstract
UNLABELLED This article presents a macroergonomic intervention in a Brazilian footwear company and its evaluation by the workers. Using participatory ergonomics, the traditional Taylor/Ford production system was transformed into a socio-technical one and tested by 100 volunteers working during 3.5 years in a pilot production line. Multiskilling and teamwork were the major changes promoted to enlarge and enrich work and make it more flexible. The workers' evaluation pre- and post-intervention showed an increase in overall satisfaction with the work and more commitment to the results and company targets. STATEMENT OF RELEVANCE This study showed that problems and solutions can be identified through participatory ergonomics, that it is easier to involve workers than the managerial staff, and that a macroergonomic intervention, mainly focusing on work organization, led to positive personnel, health and production outcomes, despite management's resistance to changes.

Abstract
OBJECTIVE With the assumption that circadian rhythms influence human performance, the work of live line electricians was reorganized and evaluated. The hypothesis was that in highly physical and attention-demanding work, the organization of tasks, according to the ideal period of day and day of week, should diminish stress and consequent work risks. BACKGROUND There are only a few studies reporting the work of electricians and even fewer approaching work organization. Moreover, these investigations often do not consider human physiological limitations and capabilities as well as task demands. METHOD A new work system was proposed with consideration of (a) the circadian cycles and homeostatic processes; (b) the effect of heat, which is a zeitgeber (synchronizer) for the biological clocks; and (c) the degree of physical and mental demands of the different performed tasks, which was assessed on the basis of opinions of the electricians and physiological markers of stress that are controlled by circadian rhythms. The traditional and new systems were compared on the basis of two cognitive indices (the arrangement of matchsticks and the perception of a minute) and three physiological markers of mental-to-physical loads (heart frequency and the level of adrenaline and noradrenaline). RESULTS Both physical and mental loads were reduced in the new system. CONCLUSION Work organization should include consideration of human circadian rhythms, mainly when stressful and high-risk tasks are involved. APPLICATION The findings can be applied in any work design, but they are especially suited for highly demanding work carried out outdoors.

Abstract
This article presents a costs-benefits analysis of a macroergonomic intervention in a Brazilian footwear company. Comparing results of a pilot line (composed by 100 multiskilled workers organized in teams) with eight traditional lines (still working in a one human being/one task model) the intervention showed to be worth pursuing since achieved gains were higher than intervention costs: there was a reduction in human resource costs (80% reduction in industrial accidents, 100% reduction in work-related musculoskeletal disorders or WMSD, medical consultations and turnover, and a 45.65% reduction in absenteeism) and production improvement (productivity increased in 3% and production waste decrease to less than 1%). The net intervention value of the intervention was around U$ 430,000 with a benefit-to-cost ratio of 7.2. Moreover, employees who worked in the pilot line understood that their quality of work life improved, compensating the anxiety brought up by the radical changes implemented.

Abstract
Objectives Small enterprises have higher exposure to occupational hazards compared to larger enterprises and further, they have fewer resources to control the risks. In order to improve the working environment, development of efficient measures is therefore a major challenge for regulators and other stakeholders. The aim of this paper is to develop a systematic model for the design of tailored intervention programmes meeting the needs of small enterprises. Methods An important challenge for the design process is the transfer of knowledge from one context to another. The concept of realist analysis can provide insight into mechanisms by which intervention knowledge can be transferred from one context to another. We use this theoretical approach to develop a design model. Results The model consist of five steps: 1) Defining occupational health and safety challenges of the target group, 2) selecting methods to improve the working environment, 3) developing theories about mechanisms which motivate the target group, 4) analysing the specific context of the target group for small enterprise programmes including owner-management role, social relations, and the perception of the working environment, and 5) designing the intervention based on the preceding steps. We demonstrate how the design model can be applied in practice by the development of an intervention programme for small enterprises in the construction industry. Conclusion The model provides a useful tool for a systematic design process. The model makes it transparent for both researchers and practitioners as to how existing knowledge can be used in the design of new intervention programmes.

Abstract
UNLABELLED This paper presents a conceptual framework that can support efforts to integrate human factors (HF) into the work system design process, where improved and cost-effective application of HF is possible. The framework advocates strategies of broad stakeholder participation, linking of performance and health goals, and process focussed change tools that can help practitioners engage in improvements to embed HF into a firm's work system design process. Recommended tools include business process mapping of the design process, implementing design criteria, using cognitive mapping to connect to managers' strategic goals, tactical use of training and adopting virtual HF (VHF) tools to support the integration effort. Consistent with organisational change research, the framework provides guidance but does not suggest a strict set of steps. This allows more adaptability for the practitioner who must navigate within a particular organisational context to secure support for embedding HF into the design process for improved operator wellbeing and system performance. PRACTITIONER SUMMARY There has been little scientific literature about how a practitioner might integrate HF into a company's work system design process. This paper proposes a framework for this effort by presenting a coherent conceptual framework, process tools, design tools and procedural advice that can be adapted for a target organisation.

The AR researchers work collaboratively with other stakeholders to solve a real-world problem: gaining insight into the problem and factors influencing solution building from an embedded position in the development process. This experience is interpreted in terms of available theory and can support further theory development. This non-experimental approach can help provide practical new approaches for integrating ergonomics considerations into real work system design processes. The AR approach suffers from a lack of acceptance by conventionally trained scientists. This paper aims to help overcome this weakness by developing the underlying theory and rationale for using AR approaches in ergonomics research. We propose further development of hybrid approaches which incorporate other evaluation techniques to extend the knowledge gains from AR projects. PRACTITIONER SUMMARY Researchers should engage directly with organisations in ergonomics projects so that they can better understand the challenges and needs of practitioners who are trying to apply available scientific knowledge in their own unique context. Such 'Action Research' could help develop theory and approaches useful to improve mobilisation and application of ergonomics knowledge in organisations.

Abstract
The aim of this study was to evaluate the implementation fidelity of a multidimensional ergonomic program designed to prevent back pain injuries among healthcare personnel. The program, provided by peer trainers included training intended to modify patient handling and transfer behaviour, trainee follow-up, prevention activities aimed at work environment improvements and follow-up monitors training. Two hundred twenty-one peer trainers at 139 Quebec healthcare institutions participated in our study. Only 61.5% were involved in training; most of them taught safe patient handling, positioning, transfer, and preparation techniques, which are the cornerstones of the program; 72.7% were involved in prevention activities, 46.1% in follow-up activities, and 10.7% in follow-up monitors training. The study results should help organizations anticipate and prevent potential discrepancies between prescribed and implemented programs.

BMC Public Health 2011; 11:840. [PMID: 22044549 PMCID: PMC3221640 DOI: 10.1186/1471-2458-11-840] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2011] [Accepted: 11/01/2011] [Indexed: 11/22/2022] Open
Abstract
Background Only a few workplace initiatives among cleaners have been reported, even though they constitute a job group in great need of health promotion. The purpose of this trial was to evaluate the effect of either physical coordination training or cognitive behavioural training on musculoskeletal pain, work ability and sickness absence among cleaners. Methods A cluster-randomised controlled trial was conducted among 294 female cleaners allocated to either physical coordination training (PCT), cognitive behavioural training (CBTr) or a reference group (REF). Questionnaires about musculoskeletal pain and work ability were completed at baseline and after one year's intervention. Sickness absence data were obtained from the managers' records. Analyses were performed according to the intention-to-treat-principle (ITT). Results No overall reduction in musculoskeletal pain, work ability or sickness absence from either PCT or CBTr compared with REF was found in conservative ITT analyses. However, explorative analyses revealed a treatment effect for musculoskeletal pain of the PCT. People with chronic neck/shoulder pain at baseline were more frequently non-chronic at follow-up after PCT compared with REF (p = 0.05). Conclusions The PCT intervention appeared effective for reducing chronic neck/shoulder pain among the female cleaners. It is recommended that future interventions among similar high-risk job groups focus on the implementation aspects of the interventions to maximise outcomes more distal from the intervention such as work ability and sickness absence.

Abstract
Swedish recycling centres are manned facilities for waste collection. There is no special category in the official injury statistics for employees at recycling centres, which precludes a straightforward analysis of reported occupational injuries. This study aimed at identifying the frequency of reported accidents and diseases and the type of events that contribute to such injuries at recycling centres, based on official injury statistics. The employees were identified as being affected by more than three to five times as many accidents compared with the total workforce in Sweden. The reported accidents had occurred during a wide range of situations, but most frequently during manual handling of waste. Reported work-related diseases were mostly associated with musculoskeletal disorders, mainly due to heavy lifting. A more detailed classification of sanitation professions and workplaces in the official injury statistics would facilitate future studies of injuries in a specific professional category, e.g. employees at recycling centres. Suggestions for prevention are given. STATEMENT OF RELEVANCE: The present article describes all reported work accidents and diseases among employees at recycling centres from 1992 to February 2005. It also highlights the problem of identifying new working groups in the official statistics and gives advice for a detailed classification to facilitate such future studies of injuries.

Abstract
Literature on ergonomic practice contains many discussions of how ergonomists should work but far less attention has been paid to how they do work and the factors that influence their practice. In an effort to improve our understanding of ergonomic practice as it occurs and how it is conditioned by broader contexts, we conducted an interview study with 21 ergonomists in Canada. We were particularly interested to understand the different kinds of activities study participants engaged in during the course of their work, the challenges they faced and the strategies they employed for facing these challenges. Findings indicate that in the course of their professional practice ergonomists engage in a variety of types of activities. This includes consulting on risk factors as well as a proactive role of fostering the application of ergonomics in organizations. The process of advocating for ergonomics brought study participants into a variety of interactions and collaborations with workplace parties in a type of activity we have called "organizational work". In the course of doing organizational work, ergonomists utilize different strategies, including "political manoeuvring", tailoring data collection and report presentations to clients' concerns and 'goal hooking' in order to make the case for implementing ergonomics in workplaces. The article concludes with a list of "tips" for practicing ergonomists that are suggested by the analysis.
