“…Using such prediction equations would allow researchers to assess the risk for a lift cycle quickly rather than assessing the whole lift cycle to obtain an accurate evaluation of risk [27].…”

BackgroundTo determine the influence of lifting speed and type on peak and cumulative back compressive force (BCF) and shoulder moment (SM) loads during symmetric lifting. Another aim of the study was to compare static and dynamic lifting models.MethodsTen male participants performed a floor-to-shoulder, floor-to-waist, and waist-to-shoulder lift at three different speeds [slow (0.34 m/s), medium (0.44 m/s), and fast (0.64 m/s)], and with two different loads [light (2.25 kg) and heavy (9 kg)]. Two-dimensional kinematics and kinetics were determined. A three-way repeated measures analysis of variance was used to calculate peak and cumulative loading of BCF and SM for light and heavy loads.ResultsPeak BCF was significantly different between slow and fast lifting speeds (p < 0.001), with a mean difference of 20% between fast and slow lifts. The cumulative loading of BCF and SM was significantly different between fast and slow lifting speeds (p < 0.001), with mean differences ≥80%.ConclusionBased on peak values, BCF is highest for fast speeds, but the BCF cumulative loading is highest for slow speeds, with the largest difference between fast and slow lifts. This may imply that a slow lifting speed is at least as hazardous as a fast lifting speed. It is important to consider the duration of lift when determining risks for back and shoulder injuries due to lifting and that peak values alone are likely not sufficient.

El levantamiento y transporte manual de cargas se asocia a los desórdenes músculo esqueléticos, los cuales representan un alto costo para los sistemas de salud y las empresas. Por tanto se requieren estrategias que mitiguen o eliminen los riesgos derivados por su ejecución. El objetivo de este trabajo fue revisar conceptos actualizados sobre los factores de riesgo, métodos de evaluación, medidas de control y prevención que se asocian al levantamiento y transporte manual de cargas. Metodología: Se revisaron artículos publicados de 2007 - 2013 en las bases de datos EBSCO, PROQUEST Y SCIENCE sobre factores de riesgo, métodos de evaluación, medidas de control y prevención asociadas al levantamiento y transporte manual de cargas. Resultados: Se revisaron 43 artículos, donde se encontró que los factores de riesgos asociados fueron la magnitud de la carga, la altura de la superficie, la frecuencia y el ritmo del levantamiento. Las metodologías de evaluación más usadas fueron el método NIOSH y los análisis de videos a través de software. Las medidas de control y prevención estuvieron relacionadas en su mayoría con el control en los individuos, de las cuales el dispositivo asistencial de levantamiento personal (PLAD) fue el más citado para controlar los riesgos. Conclusiones: El levantamiento de carga constituye un importante factor de riesgo biomecánico en la empresa. Entre las medidas de control y prevención de lesiones en la manipulación manual de cargas, tienen relevancia los controles en el trabajador.

“…the number of lifting per minute, in laboratory scale and observed that the speed of lifting had no effect on the stiffness of L3-L4 disk [23] that supported the results of the present work. However, the effect of lifting speed has been proven to be a risk factor for LBP [24,25]. With regard to similar studies on the lifting speed, it can be concluded that these studies had focused on the kinematic and kinetic parameters more than EMG results [8][9][10][11][12].…”

Purpose: Low back pain is one of the most common musculoskeletal disorders, and lifting is one of its risk factors. The activities of lumbar muscles as the main muscles involved in lifting are important with regard to identification of the allowable limits and the injury mechanisms as well as the motor control aspects. This study aimed to investigate the effects of the lifting speed on the lumbar muscles activities during the lifting of the light loads by squat method.Methods: In this study, 27 healthy men were tested using electromyography (EMG). The data were collected from the erector spinae and the multifidus muscles. The signal processing was performed using MATLAB software after normalization to MVC and the statistical analysis was performed with SPSS 16. Results:The muscles activities at fast, medium, and slow speeds were not significantly different (P>0.05); however, the difference between the numerical values of muscles activities at low and high speeds were clearly visible in the diagram. The highest activity was observed in multifidus muscles and then in erector spinae muscles. Conclusion:The results indicated that the lifting speed does not have significant effect on the activity of lumbar muscles during the lifting of light loads, but it should be noted that it can be a risk factor in the long term for individuals who are lifting a lot of loads in a day.
