Millions of workers have been uprooted by COVID-19 and been thrown into a “new normal” of working from home offices. To further complicate things, many individuals were provided with only a laptop and little, if any, education on setting up an ergonomically correct workstation.
As a result, many home office – based workers potentially face suboptimal working conditions. Workers across the nation have converted their basements, spare rooms, dining room tables or bedrooms into makeshift offices.
Kermit Davis, PhD, an expert in office ergonomics at the University of Cincinnati College of Medicine, conducted an ergonomic assessment of employees at the University of Cincinnati sending out an email survey to 4,500 faculty and staff after the coronavirus pandemic prompted the university to join many other employers across the nation in sending workers home to continue operations.
The survey had 843 people complete it. As part of the study, 41 employees sent Davis photos of workers at home workstations for ergonomic review. This subset showed some trends and offered a glimpse into what many who work from home are encountering. The survey’s findings were recently published in the scholarly journal Ergonomics in Design.
Davis says the ergonomic evaluations of the home workstations identified many issues that could be adversely affecting the workers. Many chairs were the wrong height with about 41% too low and 2% too high. Fifty-three percent of workers had armrests on their chairs, but 32% did not use them and for 18% of workers the armrests were improperly adjusted, the study found.
Davis says not using the armrests causes contact stress on forearms when rested on the hard front edge of work surfaces and strain across the upper back as the arms need support. Also, support of the back of the chair was not used by 69% and often without any lumbar support for 73% of survey participants. That meant many individuals did not have proper support of their lower back, maintaining the lumbar curvature.
The position of a computer monitor was often too low or off to the side. Three quarters of monitors were laptops, which were too low relative to the workers’ eye height, the study found. External monitors were also routinely set up too low in 52% of participants or too high in 4%. Another common issue with the monitors was the lack of the primary screens centered in front of the workers occurring in 31% of workers and resulting in twisting of the neck and/or back to view the monitor, according to the study.
Here are a few tips that might be helpful for the homebound office worker:
— Place a pillow on your seat to elevate the seat height.
— Place a pillow or rolled up towel behind your back to provide lumbar and back support.
— Wrap armrests when they are low and not adjustable.
— Move your chair closer to the desk or table to encourage having the back against the back of the seat.
— If a laptop is too low, place a lap desk or large pillow under the laptop to raise the monitor when using it on the lap.
— Use an external keyboard and mouse, along with raising the laptop monitor by placing a stack of books or a box under the laptop when using a laptop on a desk.
— An appropriate standing workstation should have the top of the monitor at eye height and directly in front, keyboard at a height so that forearms are parallel to the ground (approximately 90° elbow angle), and a soft or rounded front edge to the working surface.
— If obtaining a new chair or identifying an appropriate sitting workstation at home is not possible, rotating between a poor sitting workstation and a standing workstation would be the next best practice. There are many simple, makeshift standing workstations available in the home, including implementing the use of an ironing board, a kitchen counter, the top of a piano, a clothes basket placed upside down on a table or desk or a large box under the laptop.
