Resumen Objetivo: realizar un diagnóstico de las consecuencias de la actividad de recolección de Mora de Castilla, a partir del reporte de síntomas musculoesqueléticos percibidos por los cultivadores en el municipio de Piedecuesta, Santander. Materiales y Métodos: estudio descriptivo de corte transversal, realizado entre abril y diciembre de 2016. Se aplicó el Cuestionario Nórdico Estandarizado a 72 trabajadores; se realizaron análisis estadísticos descriptivos y de correlación de variables con el estadístico Chi-cuadrado; se incluyeron hombres y mujeres que llevasen un año o más dedicados a la labor de recolección por más de una hora al día. Se excluyeron trabajadores con enfermedades del sistema musculoesquelético de origen común u ocupacional. Resultados: el estudio encontró que el 81,9% de los agricultores tienen síntomas musculoesqueléticos en cualquier parte del cuerpo en el último año. Asimismo, un hallazgo importante de este estudio está relacionado con la prevalencia de más del 60% de dolor lumbar en el 93,5% de la población participante y corresponde a edades comprendidas entre 15 y 59. Conclusión: este hallazgo sugiere que todas las personas que participan en la cosecha de Mora de Castilla están trabajando en condiciones de dolor y toda la población estudiada está expuesta a síntomas musculoesqueléticos.

Abstract Objective: To make a diagnosis of the consequences of the collection activity of Andean Raspberry based on the report of musculoskeletal symptoms perceived by growers in the municipality of Piedecuesta, Santander. Materials and methods: Descriptive cross-sectional study carried out between April and December 2016. The Standardized Nordic Questionnaire was applied to 72 workers and descriptive statistical analysis and correlation of variables were performed with the Chi-square statistic test. Men and women who had been engaged in harvesting for a year or more for more than one hour daily were included. Workers with diseases of the musculoskeletal system of common or occupational origin were excluded. Results: the study found that 81.9% of the farmers had experienced musculoskeletal symptoms in any part of the body in the last year. Also, an important finding of this study is related to the prevalence of more than 60% of low back pain in 93.5% of the participating population and corresponds to ages between 15 and 59 years. Conclusion: this finding suggests that all people participating in the harvest of Andean Raspberry are working in pain conditions and the entire population studied is exposed to musculoskeletal symptoms.

Dispositivo ergonómico para el mantenimiento y reparación de herramientas instrumentales ILI / Ergonomic device for the maintenance and repair on in-line inspection (ILI) tools

Objetivo: Realizar un análisis ergonómico comparativo de un nuevo dispositivo diseñado (MSILT) con el Banco MTN actual. Métodos: Por medio de OWAS se evaluaron las tareas con mayor riesgo, luego se realizó la simulación digital humana en un entorno virtual y se evaluaron los esfuerzos y la carga estática articular. Asimismo, se realizó un análisis comparativo utilizando el software Jack de Siemens. Resultados: Se obtuvo una reducción a la exposición de riesgos de carga física, se pasó de posturas que pueden tener efectos dañinos sobre el sistema musculoesquelético (categoria 4) a posturas neutrales (categoría 1). También se redujo la carga estática en las articulaciones y la carga intradiscal por debajo del valor límite de 3400 N según la National Institute for Occupational Safety and Health (NIOSH). Conclusiones: El estudio establece que la propuesta de diseño del dispositivo (MSILIT) es viable y puede ser implementada en aquellas empresas del sector de hidrocarburos

Objective: We conducted a comparative ergonomic study of a new workplace station (MSILT) and a standard wooden industrial workbench. Methods: First, we used the OWAS method to evaluate the highest risk tasks. Next, we used human digital simulation in a virtual environment to evaluate stress on low back and joint load. We also performed a comparative analysis using the Siemens Jack software. Results: There was an overall reduction in exposure to physical loads. Awkward postures decreased from a category 4 (harmful) to category 1 (neutral) risk level. There was also a reduction in static loads on the joints and intradiscal loading to below the National Institute for Occupational Safety and Health (NIOSH) recommended level of 3400 N. Conclusion: This study demonstrated the feasibility of the new MSILIT and that it can be implemented in the hydrocarbons industry

Influence of seat tilt motion on discomfort perception during a simulated driving activity.

BACKGROUND: Discomfort perceived in activities where there is a prolonged sitting posture are normally compensated in a natural way by means of macro-repositioning movements in the seat. Nevertheless, evidence shows that such movements are not able to palliate discomfort due to lumbar pain. OBJECTIVE: This study involves research performed to demonstrate whether induced postural changes are able to mitigate this type of discomfort during a simulated driving activity. METHODS: Twenty-four subjects with lumbar pain (LBP) and without lumbar pain (WLBP) underwent 90 min of simulated driving activities while periodic variations of seat tilt (Tt) were implemented. RESULTS: Discomfort perception due to lumbar pain significantly decreased in the case of Tt compared with the case of WTt (without seat tilt), and significant differences were found (p = 0.02). However, treatments with Tt indicated that no substantial differences exist between LBP and WLBP subjects when considering discomfort perception due to lumbar pain and the erector spinae activity. CONCLUSIONS: This study revealed that periodic variations on seat tilt can help to reduce discomfort perception due to lumbar pain during driving activities, regardless of the health condition of the subject.
