“…Since the NIOSH lifting equation is not intended to evaluate differences between lifting techniques 25 , based on the results of this study, it might be an appropriate approach to evaluate with OWAS or REBA instead of the NIOSH lifting equation when manual material handling is performed with a high variance in lifting technique. Latest research reveal that real-time feedback of such underlying parameters, especially outcomes of biomechanical models, can improve the lifting technique in MMH 51 , 52 .…”

The validity of observational methods in ergonomics is still challenging research. Criterion validity in terms of concurrent validity is the most commonly studied. However, studies comparing observational methods with biomechanical values are rare. Thus, the aim of this study is to compare the Ovako Working Posture Analysing System (OWAS) and the Rapid Entire Body Assessment (REBA) with in vivo load measurements at hip, spine, and knee during stoop and squat lifting of 14 participants. The results reveal that OWAS and REBA action levels (AL) can distinguish between different in vivo load measurements during manual lifting. However, the results also reveal that the same OWAS- and REBA-AL do not necessarily provide equal mean values of in vivo load measurements. For example, resultant contact force in the vertebral body replacement for squat lifting ranged from 57% body weight (%BW) in OWAS-AL1 to 138%BW in OWAS-AL3 compared to 46%BW in REBA-AL0 and 173%BW in REBA-AL3. Furthermore, the results suggest that the performed squat lifting techniques had a higher risk for work-related musculoskeletal disorders than the performed stoop lifting techniques.

“…Las instrucciones visuales de MMC con retroalimentación individual en tiempo real de la fuerza de compresión del disco intervertebral L5/S1, tienen ventajas significativas en la mejora de la técnica de elevación en comparación con las instrucciones solo teóricas. Por lo tanto, el uso de esta herramienta podría ser un elemento adecuado para la instrucción en programas de entrenamiento de MMC para reducir o prevenir el dolor lumbar en el futuro (Brandl, 2022).…”

A pesar del creciente grado de mecanización y automatización en la industria, las tareas de manipulación manual de materiales (MMC) siguen siendo una característica importante de muchas faenas industriales. Es interesante que la introducción de la mecanización y la automatización en el lugar de trabajo no elimine la necesidad de realizar tareas de MMC. La siguiente revisión tiene como objetivo analizar los factores intrínsecos existentes, descritos en la literatura, durante la realización del MMC para ser considerados como estrategia de mitigación de riesgos, todos ellos identificados a través de la base de datos electrónica ScienceDirect seguido de una búsqueda manual por el autor. Se seleccionaron 21 estudios elegidos por criterios. El manejo de los factores internos permite adoptar estrategias de mitigación de los riesgos por MMC y pueden ser considerados frente a los riesgos presentes durante esta actividad.

“…One of the manual jobs will have a high risk if it is not done ergonomically. One of them will be "over exertion", namely damage to the body's muscles caused by excessive lifting weights [2].…”

The role of humans as workers is still dominant in carrying out the production process, especially activities carried out manually in Material Handling (MMH). Activities carried out using the MMH method are identified as having a high risk if they are not carried out ergonomically and with a good work system, musculoskeletal complaints can occur due to wrong work postures and physical workload. The production process for SME Barokah Tofu in Kendal Regency is still carried out manually by employees who have identified incorrect work postures due to musculoskeletal complaints and physical workload. Therefore, it is necessary to analyze work posture and physical workload of Barokah Tofu employees who have a high risk to reduce musculoskeletal complaints and high physical workload, as well as provide suggestions for improvements to Barokah Tofu. The methods used in this research are ERIN (Evaluation Del Riesgo Individual) and CVL (Cardiovascular Load). Based on the calculation results, it can be concluded that there are 2 activities that have the results of the classification of work posture and physical workload inversely, namely soybean milling and moulding of tofu where work posture has a high risk and physical workload has a low risk, and there are 2 activities that have a work posture classification result. and the physical workload is directly proportional, namely filtering cooking products with low risk and cutting tofu with high risk. Activities that have a high risk require suggestions for improvements, namely simulation of tool design and Standard Operating Procedures (SOP) for the application of ergonomic principles at work.
