Despite decades of research into patient falls, falls and the injuries incurred continue to be a serious threat to patient safety. Fall rates continue to be unacceptably high. The purpose of this project is to increase the safety of a hospital room for patient mobility through patient-centric design.
This survey is a starting point to understanding and quantifying the effect object characteristics have on a patient’s safety and stability when used for support. Based on the results of the survey, the next step of my research is to quantify the relationship between height, resistance to movement, and type of grasp and how those three characteristics work together to provide stability to a frail individual. This will be done in a laboratory setting using motion capture.
Here is a 3-minute supplemental video explaining the results of the survey.

Melynda Schreiber, Dorothy Taylor, Sergei Sarkisian and Uchenna Ogbonnaya participated in a 1.5 day symposium at Auburn University on Exposure Assessment. We had a great time with trainees from Auburn, Iowa and Colorado State. Thanks for the great hospitality and stimulating discussion. Our future is in good hands!
Prof. Merryweather and members of the Ergonomics and Safety Lab had a big presence at IMCEC 2019 (https://event.asme.org/IMECE).

The University of Utah’s Rocky Mountain Center for Occupational and Environmental Health (RMCOEH) and Department of Mechanical Engineering will be holding the 17th Annual Regional National Occupational Research Agenda (NORA) Young/New Investigators Symposium.
The goal of this conference is to assemble interested students (undergraduate and graduate) and young/new investigators from the region, as well as other interested parties, in a forum where NORA-related research can be presented and discussed in a non-threatening atmosphere. It is expected that, for many of the students who choose to present, it will be the first formal presentation of their research.
The NORA 2019 Conference will be held at the Officer’s Club 150 Fort Douglas Blvd, Salt Lake City, UT 84113 on April 18th & 19th. Please visit the NORA 2019 website for the latest information.
There will be two special presentations this year at NORA. The Opening Keynote Speaker is Sarah A. Felknor, DrPH. Her talk is entitled Expanded Focus for Occupational Safety and Health and will start at 8:30 AM on April 18th.
At 8:30 AM on April 19th, the Dr. Paul S. Richards Endowed Distinguished Visiting Lectureship in Occupational Medicine will present Donald C. Sinclair, II, J.D., who will speak on The Role of the Epidemiological and Exposure Sciences in the Resolution of Medicolegal Disputes.
Mr. Sinclair, Esq.
The Richards Lecture is FREE and open to the public, however, registration is required. To register for this lecture ONLY, register for attendance with the “Richards Lecture Only” option at the NORA 2019 website.
Moriah Henning, a senior in Mechanical Engineering, presented a poster at the Utah Conference for Undergraduate Research (UCUR) at Weber State on Friday, February 22nd. The conference is modeled after the National Conference for Undergraduate Research and invites undergraduates from all disciplines to apply. It provides a great opportunity for undergraduates to share their work in a scholarly setting to other students, faculty, and community members from all over Utah.
Moriah completed two semesters of research under Dr. Andrew Merryweather on characterizing the open-source, 3D-printed, InMoov robotic hand as part of the the Undergraduate Research Opportunities Program (UROP). She analyzed the hand’s limitations and abilities through computer and physical testing to better understand improvements that could be made to the design. Presenting at UCUR gave her the opportunity to meet other undergraduate students doing research and to share her own research outside the lab.
Mr. Jon Mortensen traveled to Washington D.C. Sept. 26-28 for the Third IEEE/ACM Conference on Connected Health: Applications, Systems, and Engineering. He presented work aimed at improving simple ergonomic risk evaluation tools (such as RULA) through the use of OpenSim musculoskeletal models. OpenSim models output biomechanical data that may offer higher resolution on injury risk than previous tools.
The 7th National Occupational Injury Research Symposium – NOIRS – was held October 16-18, 2018 in Morgantown, WV.
NOIRS is the only national forum focused on the presentation of occupational injury research. The Symposium brings together researchers, academicians, labor union representatives, safety professionals, industry leaders, and students from multiple disciplines and fields to advance the public health mission of keep workers safe. This year’s theme was: Advancing Worker Safety in the 21st Century Through Research and Practice.
Advised by mechanical engineering assistant professor Andrew Merryweather, the senior design project Wearable Tremor Damping Device, was selected as one of the six finalists for the 2018 Undergraduate Design Project Competition in Rehabilitation and Assistive Devices at the 8th World Congress of Biomechanics July 8-12, 2018, Dublin, Ireland. There the team was given the opportunity to present their design at a special podium presentation.
Ms. Mikaela Hayward and Prof. Andrew S. Merryweather are pictured above in Dublin. The entire team is pictured below and from, left to right, are MEEN BS 2018 Seniors Kory Cross, Irsyad Badri, Mikaela Hayward, Quincy Stevens, and Hyrum Peterson.
Jon Mortensen and Mitja Trkov presented their work at the 20th Congress of the International Ergonomics Association in Florence, Italy. Jon presented a new modeling approach to evaluate falls using OpenSim, and Dr. Trkov presented work related to the Lifting Coach.

Dr. Merryweather and his colleagues were awarded the Liberty Mutual Medal for 2017 at the 20th Congress of the International Ergonomics Association in Florence, Italy. The team was recognized last year for their contributions to the field of workplace safety and ergonomics. Dr. Stephen Boa (First Author) presented work on behalf of the research team.
(2016) Relationships between job organisational factors, biomechanical and psychosocial exposures, Ergonomics, 59:2, 179-194, DOI: 10.1080/00140139.2015.1065347
The relationships between work organisational, biomechanical and psychosocial factors were studied using cross-sectional data from a pooled dataset of 1834 participants. The work organisational factors included: job rotation, overtime work, having second jobs and work pace. Task and job level biomechanical variables were obtained through sub-task data collected in the field or analysed in the laboratory. Psychosocial variables were collected based on responses to 10 questions. The results showed that job rotations had significant effects on all biomechanical and most psychosocial measures. Those with job rotations generally had higher job biomechanical stressors, and lower job satisfaction. Overtime work was associated with higher job biomechanical stressors, and possibly self-reported physical exhaustion. Those having second jobs reported getting along with co-workers well. Work pace had significant influences on all biomechanical stressors, but its impact on job biomechanical stressors and psychosocial effects are complicated.
Practitioner Summary: The findings are based on a large number of subjects collected by three research teams in diverse US workplaces. Job rotation practices used in many workplaces may not be effective in reducing job biomechanical stressors for work-related musculoskeletal disorders. Overtime work is also associated with higher biomechanical stressors.
