Do workplace inventions prevent low-back disorders? If so, why?: a methodologic commentary
Article Abstract:
There is a dramatic increase in the requirement for worksite interventions to prevent low-back disorders yet there is dissent within the field of ergonomic and related disciplines as to whether or not various proposed interventions work. A study presents two individual cases to attempt to determine why findings regarding low back disorder prevention programs have been so inconclusive. It is suggested that more exploratory studies on this subject may be conducted by building on previous, pragmatically-oriented research.

The effectiveness of commonly used lifting assessment methods to identify industrial jobs associated with elevated risk of low-back disorders
Article Abstract:
Back problems are second only to the common cold as to why most people visit doctors and low-back problems are contemporary society's most costly and common musculoskeletal problem. A study was conducted to assess the validity and effectiveness of commonly used evaluation methods used to control low-back disorders in the workplace and their sensitivity as well as specificity. An objective criterion-oriented database was used for the study.

Quantification of back motion during asymmetric lifting
Article Abstract:
The dynamics of human trunk motion during asymmetric manual lifting chores are examined in terms of seven task asymmetries and three task weights in an experiment. The extent of motion, velocity and acceleration in the trunk are quantified and these are used to demonstrate the linear proportionality between trunk motion properties and task asymmetry. The negative effect of the asymmetric trunk motion on the trunk strength is also proven.
