A participatory ergonomics intervention to reduce risk factors for low-back disorders in concrete laborers

Identificación de malestares músculo-esqueletales en una planta de manufactura en Los Olivos, Lima-Perú

“…El uso de la ergonomía participativa ha tenido resultados concretos en la mejora de las condiciones de trabajo, la productividad y la calidad de vida del trabajador (Haukka et al, 2008;Hess, 2004;Kogi, 2006;Laitinen et al, 1998;Liker et al, 1989;Loisel et al, 2001;Rivilis et al, 2008;Vink et al 1995), en la reducción de accidentes de trabajo (Lanoie y Tavenas, 1996) y en la mejora de procesos a nivel organizacional (Haims y Carayon, 1997;Maciel, 1998). El concepto de ergonomía participativa surgió hace aproximadamente tres décadas.…”

Explicit and implicit theories of change when designing and implementing preventive ergonomics interventions – a systematic literature review

“…Thirteen of these publications referred to an explicit theory or model concerning the process of change (17,(57)(58)(59)(60)(61)(62)(63)(64)(65)(66)(67)(68). Altogether, 12 different theories, named by the publications as cited below, were identified in the reviewed papers.…”

“…Referring to a specific theory, but vaguely explaining how the intervention relates to that theory N=1 (58) Referring to a specific theory; strategy for implementation firmly rooted in theory N=12 (17,57,59,64,(77)(78)(79)(80)(81)(82)(83)(84) No reference to a change theory, and no reference for the intervention strategy either N= 4 (87,88,90,96) Referring to results from previous research, but not stating a particular theory of change N=13 (66,85,86,89,(91)(92)(93)(94)(95)(97)(98)(99)(100) Intervention strategy …”

“…Altogether, 12 different theories, named by the publications as cited below, were identified in the reviewed papers. Theories containing (elements of) participatory ergonomics were the most frequently referred to by five studies in total (57,58,64,65,67). These were referred to as a cooperative inquiry model; reactive ergonomics intervention process or participatory theory/model.…”

“…This model illustrates the extent to which authors argue for the pedagogical ideas conveyed in their texts and not simply take them for granted. Thirteen articles (17,(57)(58)(59)(60)(61)(62)(63)(64)(65)(66)(67)(68) reported interventions with reference to an explicit theory of change, and also established the change strategy firmly on basis of that theory; these articles were thus assigned to the upper right quadrant (figure 1). For example, a study might explicitly claim to base its intervention on the theory of diffusion of innovation (90) and consequently employ a strategy involving participants in the change process, relying on extensive communication as a core element.…”
