Friday Five – 4/28/17

The Friday Five is a set of five links that I have come across this week that pertain to ergonomics, occupational health, safety, human performance, or human factors.  For whatever reason, I found them interesting, but they are provided with minimal or no commentary and are not meant to be endorsement for a given product or research paper.

These links were generated during a PubMed search on the terms: applied ergonomics

Lee et al. investigated the position of two different wearable sensor systems on the posture of construction workers while performing assigned tasks in a laboratory.  As those who have worked with motion capture devices know, placement of these sensors is everything in terms of collected data.

He et al. look at using Google Glass to monitor eye blinking in drivers to determine signs of drowsiness.  Distracted driving is something that we’ve hit upon in other posts.  Technology such as this may be able to go along way in helping drivers to recognize when they are too fatigued to drive safely.

Schmidt et al. investigated a different way of dealing with fatigue during long drives through the use of a cooling device to help improve alertness.

Armstrong et al. reviewed the impact of two paramedic services transitioning to a powered stretcher to help reduce injuries related to patient transport.  This appears to be a cost-effective solution with a reduction in injuries during patient transport.

Hlavenka et al. investigated the effect of neck posture during lifting tasks on both lumbar spine posture and activation of trunk musculature.  They indicate that a retracted neck posture may help to lower the risk of pain and injury during lifting tasks.

 

Friday Five – 3/31/17

The Friday Five is a set of five links that I have come across this week that pertain to ergonomics, occupational health, safety, human performance, or human factors.  For whatever reason, I found them interesting, but they are provided with minimal or no commentary and are not meant to be endorsement for a given product or research paper.

This week’s five are courtesy of a PubMed search on the terms: applied ergonomics

Manghisi et al. look at the use of the Kinect V2  (the newer generation of the Kinect) for performing RULA assessments to evaluate awkward postures.  Devices like the Kinect are interesting to me as they may allow for more natural evaluations of human movement in real life work settings.

Sedighi Maman et al. look at the use of wearable technologies for evaluating a data driven model for physical fatigue in the workplace.

JA Dobson et al. provide a literature review of work boot design and the impact on how workers walk(This is an important topic area that came up yesterday when we were in the field performing assessments for a customized job description.  The particular job has a variety of varied tasks with some that require steel toed boots.  The biggest complaint of the employees is comfort of steel toed boots for the tasks performed.)

Kang and Shin performed a study to determine the impact on accuracy and muscle activation patterns when target location is varied on computer touch screens.  This is going to be an important area for human factors and user interface professionals as touch screens become more common in the workplace.

Plamondon et al. look at the differences in how male and female workers lifting palletized loads with the same relative weight.   This study uses a similar lifting load weight to remove strength from the equation when looking at how the task is performed biomechanically.  While patterns between male and female subjects were similar, interjoint coordination differs.  Understanding of these differences can help with interventions to better reduce material handling injuries.
