Research Review: Force and Repetition Combine to Affect MSD Risk

Force and repetition are two well-known risk factors for musculoskeletal disorders (MSDs). Contributor Sean Gallagher shares the key points and findings resulting from a recent review of scientific articles he and study co-author John Heberger performed. They note that many current ergonomic tools and guidelines consider the factor of repetition to have the same impact on MSD risk no matter the level of force involved. However, their review, published in the journal Human Factors, indicates that it may be the way these two factors are combined that is most important in the development of MSDs.

Driver Distraction: Glance Patterns and Durations, More Research Needed

The advent and prevalence of mobile phones, texting, and interactive vehicle dashboards have brought concerns over driver distraction to the forefront. Peter Budnick reviews new research that attempts to investigate the relationship between eye-glance duration, location and history to driver distraction and the likelihood of a crash. The authors rely on real-world driver data collected before the prevalence of mobile devices, but they're biggest finding is that we need better real-world driving data before we can precisely understand eye-glancing as it relates to driver distraction and resulting crashes.

Sit vs. Stand: Who Benefits from Sit-to-Stand Workstations?

There are many potential benefits from sit-to-stand and user adjustable furniture, including lower total cost of ownership, fewer MSD's, higher productivity, improved satisfaction, etc. However, to get the greatest benefit for the employee and the company, you need to ensure that you deploy the right equipment to the right population, and then support roll-out by giving users encouragement and guidance in how to be comfortable and successful with the new equipment. This article provides background for the benefits of sit-to-stand workstations, and guidance on how to effectively implement them on a small or large scale basis.

Checklists Improving Outcomes for ICU and Surgical Patients

In this article, originally published in 2009 in The Ergonomics Report, journalist Jennifer Anderson describes a campaign to persuade intensive care physicians and surgeons that the humble checklist offers an effective means of reducing medical errors and complications. The World Health Organization added its weight to the effort. Has your hospital implemented such basic, necessary and straightforward ergonomics as a means to improve patient care and outcomes?
