Interface stability influences torso muscle recruitment and spinal load during pushing tasks

Article Abstract:

The aim of the study is to provide insight into the role of interface stability with regard to torso muscle recruitment and biomechanical loads on the spine. The study concluded that handle or interface design and stability may influence spinal load and associated risk of musculoskeletal injury during manual materials tasks that involve pushing exertions.

Effects of antagonistic co-contraction on differences between electromyography based and optimization based estimates of spinal forces

Article Abstract:

A study was conducted to compare electromyography based and optimization based estimates of spinal forces in a wide range of work tasks. The results show that neither neglecting antagonistic co-contraction, nor assuming equal activation of deep and superficial muscles has a major effect on estimates of spinal forces.

An evaluation of predictive methods for estimating cumulative spinal loading

Article Abstract:

In order to evaluate the amount of error present in different approaches that have been commonly used to predict the cumulative spinal loading during manual materials handling tasks, a study is conducted. The results show that errors in cumulative estimates depend largely upon the approach used.
