Spinal loading during manual materials handling in a kneeling posture.
Stooped, restricted, kneeling, and other awkward postures adopted during manual materials handling have frequently been associated with LBP onset. However, lift assessment tools have focused on materials handling performed in an upright, or nearly upright standing posture. Unfortunately, many of the tools designed to analyze standing postures are not easily adapted to jobs requiring restricted ...
متن کاملUsability of manual handling aids for transporting materials.
Manual transport aids (trucks and trolleys) are in widespread use throughout most industries, but their use does not always result in the anticipated reduction of workload or musculoskeletal stress. A survey of users has shown that many of the aids currently used are poorly designed or inappropriate for the tasks performed. The information gained during the survey has been analysed to identify ...
متن کاملEvaluation and quantification of manual materials handling risk factors.
This study investigated the ability of the Revised NIOSH Lifting Equation (RNLE) to measure the risk of low back injury as verified by employee health outcomes. In addition, several basic risk factors and combinations of risk factors presumed related to low back disorders were explored. The RNLE was modified to allow analysis of one-handed and two-handed, asymmetric lifts. Predictive performanc...
متن کاملPredicting Foot Positions for Manual Materials Handling Tasks
For many industrial tasks (push, pull, lift, carry, etc.), restrictions on grip locations and visibility constrain the hand and head positions and help to define feasible postures. In contrast, foot locations are often minimally constrained and an ergonomics analyst can choose several different stances in selecting a posture to analyze. Also, because stance can be a critical determinant of a bi...
متن کاملImplicit Cues Modify Manual Materials Handling Behaviour but Not Safe Handling Affordance
INTRODUCTION Observation-based occupational safety programs have long recognized the critical interaction of environment and behaviour in the workplace [1]. While the veracity of these programs is questioned [2], their foundation in behavioural psychology connects to various theory-based paradigms for changing manual materials handling (and musculoskeletal loading, or `consequences`) by manipul...
