Resumen

El objetivo de este estudio era comparar los efectos de dos sistemas diferentes de gestión de cargas (un sistema motorizado, el RazerLift®, y un sistema tradicional) sobre el esfuerzo biomecánico y percibido experimentado por los trabajadores al realizar tareas rutinarias de carga y descarga de escaleras. Siete trabajadores experimentados realizaron tareas de carga y descarga de escaleras. En comparación con el sistema tradicional, la fuerza de compresión estática acumulada en la zona lumbar se redujo en un 57,9% (p < 0,05) y un 39,3% (p < 0,05) cuando se utilizó el RazerLift® para realizar tareas de carga y descarga de escaleras, respectivamente. En general, los momentos acumulativos de flexión del hombro se redujeron en un 34,8% (p < 0,05) y un 41,3% (p < 0,05) cuando se utilizó el RazerLift® para realizar las tareas de carga y descarga de la escalera, respectivamente. En general, la puntuación del esfuerzo percibido se redujo en un 250,1% (p < 0,05) cuando se utilizó el RazerLift® en comparación con el sistema tradicional. En conclusión, nuestro estudio demostró que el RazerLift® reduce la exposición biomecánica y psicofísica asociada al desarrollo de trastornos musculoesqueléticos durante la realización de tareas de carga y descarga de escaleras.
