OBJECTIVES Existing methods for practically evaluating musculoskeletal exposures such as posture and repetition in workplace settings have limitations. We aimed to automate the estimation of parameters in the revised United States National Institute for Occupational Safety and Health (NIOSH) lifting equation, a standard manual observational tool used to evaluate back injury risk related to lift...

background: manual handling, lifting, or carrying of material is responsible for non-fatal injuries among employees in industries. it is the second most prevalent reported risk factor in workplaces that can lead to potential manual handling accidents and longer-term musculoskeletal disorders (msds). the aim of this study was the evaluation of manual material handling using the american national...

Low-back disorders (LBD) continue to be the most costly and common musculoskeletal problem facing society today. Investigators have developed tools or measures that are intended to identify jobs that will probably be associated with an elevated risk of low-back disorders. However, an important and not widely discussed issue associated with these tools and procedures has been that of the validit...

The aims of the present work were: to calculate lifting energy consumption (LEC) in work activities designed to have a growing lifting index (LI) by means of revised NIOSH lifting equation; to evaluate the relationship between LEC and forces at the L5-S1 joint. The kinematic and kinetic data of 20 workers were recorded during the execution of lifting tasks in three conditions. We computed kinet...

The 1991 NIOSH (National Institute for Occupational Safety and Health) revised lifting equation’s objective is to prevent or reduce lifting-related injuries, especially of the low back. However, the lifting equation is only applicable to two-handed lifting tasks. Oneand twohanded repetitive lifting tasks are a consistent part of many occupations. Understanding the metabolic demands of oneand tw...
