Prospective validation of a low-back disorder risk model and assessment of ergonomic interventions associated with manual materials handling tasks

Article Abstract:

This article discusses a study conducted to determine if an ergonomic assessment tool, low-back disorder risk assessment model, can predict the possibility of lower back injuries associated with materials handling tasks. The authors conclude that the utilization of the model successfully assessed the potential of tasks to lead to lower back injuries.

The future of research in understanding and controlling work-related low back disorders

Article Abstract:

A brief description on the research in understanding and controlling work-related low back disorders (LBD) is presented. The findings along these silos are interrelated and could be explained in terms of changes in the biomechanical loading at the tissue level.

Effects of box features on spine loading during warehouse order selecting

Article Abstract:

Low back disorders (LBD) are often associated with occupational factors, and manual material handling (MMH) tasks are linked to most LBDs. An electromyographic (EMG)-assisted model was developed to evaluate dynamic lifting under realist work conditions. Biomechanical load assessment measures were used to examine the effect of transferring boxes of differing size and weight from different positions. Mean maximum L5/S1 compression forces and A/P shear forces were reduced by the presence of handles on the boxes, box weight had a significant effect on spinal loading and the area from which the boxes were lifted had a profound effect on compression.
