No evidence for an effect of working from home on neck pain and neck disability among Swiss office workers: Short-term impact of COVID-19

Digital human ergonomics training for remote office workers: Comparing a novel method to a traditional online format

OBJECTIVE

This randomized controlled trial investigated the effectiveness of an online ergonomics training program with a digital human compared to an online ergonomics training program without a digital human.

METHOD

Remote office workers (n = 138) were randomly assigned to either a digital human training, a traditional webpage training without a digital human, or a control group. Musculoskeletal discomfort, knowledge retention, and behavior change were measured.

RESULTS

The overall group differences for increased behavior change and knowledge retention were statistically significant (p < 0.05). For knowledge retention, the digital human training group showed comparable improvement in knowledge scores compared to the traditional training group. For behavior scores, the traditional training showed improvement compared to the control group. Decreases in musculoskeletal discomfort for all groups were not statistically significant (p > 0.05).

CONCLUSION

Digital humans have the potential to meet large-scale remote worker training needs.

Chronic Neck Pain Prevalence Before and After COVID-19 Restrictions and Its Relationship With Digital Device Screen Viewing: A Population Study

OBJECTIVE

To estimate the prevalence of chronic neck pain (CNP) among the adult population in Peru during the post-coronavirus disease 2019 (COVID-19) restriction period compared with that during the pre-pandemic period and evaluate its association with prolonged digital devices connected to the internet (DDCI) screen viewing.

METHODS

We conducted a cross-sectional study using a representative sample of adults living in Peru in November 2022. A structured survey was employed to identify CNP, and the exposure variable was set as the duration of DDCI screen viewing. The McNemar test was used to compare CNP prevalence pre- and post-COVID-19 restrictions, and ordinal logistic regression was used to evaluate its association with prolonged screen viewing.

RESULTS

A total of 1,202 individuals participated, with 52.8% females and 79.9% residing in urban areas. Following the restrictions, the prevalence of CNP occurring daily or almost daily and at least once a week was 14.8% and 27.8%, respectively (95% confidence Interval [95% CI], 12.6-17.3 and 24.9-30.9), representing a significant increase (p<0.001) compared with pre-pandemic estimates. Notably, among those viewing DDCI screens for ≥8 hours, the odds ratio for CNP frequency escalation compared with those who did not or rarely view screens was 1.61 (95% CI, 1.04-2.50; p=0.033).

CONCLUSION

Approximately 4 of 10 adults in Peru experienced CNP following the lifting of COVID-19 social restrictions, more than double the pre-pandemic prevalence. Furthermore, prolonged viewing of DDCI screens increased the risk of having this condition.

Chronic pain and associated factors in remote work during the COVID-19 pandemic in Brazil

OBJECTIVE

Estimate the prevalence of chronic pain and its association with symptoms of anxiety, sleep disorders, and aspects of remote work in the context of the COVID-19 pandemic.

METHOD

A cross-sectional and descriptive study conducted with 328 adults engaged in remote work. Data was collected online from February 2021 to January 2022. For pain investigation and evaluations of sleep and anxiety, a structured questionnaire, the Pittsburgh Sleep Quality Index, and the Generalized Anxiety Disorder-7 were used, respectively.

RESULTS

The prevalence of chronic pain was 47.9% (CI 95% = 42.5-53.3). Associations were identified between pain and anxiety, sleep disorders, and sitting time (p<0.01).

CONCLUSION

The prevalence of chronic pain in remote work was found to be high, with pain being of moderate intensity and associated with anxiety, sleep disorders, and prolonged sitting time.

Can working at home be a hazard? Ergonomic factors associated with musculoskeletal disorders among teleworkers during the COVID-19 pandemic: a scoping review

Objectives. The improvised and massive adoption of remote work in the context of COVID-19 has forced us to adapt homes as workspaces, which could promote development of musculoskeletal disorders (MSDs). This review explores the evidence for ergonomic factors associated with MSDs in teleworkers. Methods. A literature search was conducted in MEDLINE, Embase, Scopus, SciELO and EBSCO. We included observational studies published between March 2020 and October 2021 that included teleworking personnel due to the restrictions of the pandemic. Results. A total of 212 studies were identified, 14 were chosen for complete review. Associated factors were change of work modality (on-site work to telework), use of home environments as workspaces (areas not adapted for work and with low lighting), working furniture (non-ergonomic chairs and desks), use of electronic devices (tablets, cell phones and laptops), organizational factors (working hours, active breaks, sitting time) and individual factors (physical activity practice). Conclusion. Various ergonomic home factors and the characteristics of teleworking - mainly furniture, the environment of work and physical activity - are associated with MSDs. This evidence suggests that the norms and regulation of telework can consider the adaptation of workspace and conditions at home to prevent health problems in the medium and long term.

Analysis of real-world visual ergonomics at the visual display unit

INTRODUCTION

In this interventional study, the ergonomic workplace set-up and the impact of character size on subjectively estimated working productivity and computer vision syndrome (CVS) were evaluated in the field.

METHODS

The number of displays and their size, resolution, surface structure, position in the room and relation to the eye were evaluated for 152 units. CVS was assessed using the CVS-Questionnaire. Habitually used character size for an uppercase E was recorded and compared to the ISO 9241-303:2011, national standards (e.g., ANSI/HFES 100-2007) and national guidelines (e.g., German DGUV Information 215-410). In case of failure to comply with these standards, character size was increased to 22 angular minutes to reach the recommended ranges. Reasons for returning to former or smaller character sizes were recorded, and subjectively perceived changes in productivity were estimated by the participants using a visual analogue scale before and 2 weeks after the intervention using a questionnaire.

RESULTS

The average visual display unit consisted of two non-glare (matt) 24″ widescreen monitors that were located approximately 73 cm (primary) and 76 cm (secondary) from the eyes. The mean (SD) habitually set character size was 14.29 angular minutes (3.53) and therefore both statistically and clinically significantly too small compared with ISO 9241-303:2011 (p < 0.001). Increasing the character size to 22 angular minutes produced a 26% reduction in subjectively rated productivity (p < 0.001). No significant correlation between character size and symptoms of CVS was demonstrated.

CONCLUSIONS

In the workplaces investigated, recommendations for character size were not adhered to. This resulted in a reduction in productivity and was not compatible with some of the work requirements, for example, obtaining a broad overview of a spreadsheet.

Teleworking and Musculoskeletal Disorders: A Systematic Review

Teleworking has spread drastically during the COVID-19 pandemic, but its effect on musculo-skeletal disorders (MSD) remains unclear. We aimed to make a qualitative systematic review on the effect of teleworking on MSD. Following the PRISMA guidelines, several databases were searched using strings based on MSD and teleworking keywords. A two-step selection process was used to select relevant studies and a risk of bias assessment was made. Relevant variables were extracted from the articles included, with a focus on study design, population, definition of MSD, confounding factors, and main results. Of 205 studies identified, 25 were included in the final selection. Most studies used validated questionnaires to assess MSD, six considered confounders extensively, and seven had a control group. The most reported MSD were lower back and neck pain. Some studies found increased prevalence or pain intensity, while others did not. Risk of bias was high, with only 5 studies with low/probably low risk of bias. Conflicting results on the effect of teleworking on MSD were found, though an increase in MSD related to organizational and ergonomic factors seems to emerge. Future studies should focus on longitudinal approaches and consider ergonomic and work organization factors as well as socio-economic status.

Assessment of Forward Head Posture and Ergonomics in Young IT Professionals - Reasons to Worry?

BACKGROUND

 Prolonged computer use and poor ergonomics among IT professionals are considered risk factors for musculoskeletal disorders. This research aims to analyze the degree of forward head posture and workplace ergonomics in young IT professionals to assess the risk for a neck disability. Methods: A prospective study was carried out by assessing the sitting posture at work, neck disability in the cervical region, quality of life, physical activity, and ergonomics of the workspace in 73 young IT professionals (32.56±5.46 years). Results: The score for the cervical functional disability index (NDI) showed a mild neck disability (8.19±7.51). The craniovertebral angle has an average value of 32.01±11.46, corresponding to a light forward head posture, and it positively correlated with age and work experience and negatively correlated with ROSA (r=0.24, p<0.05). The NDI positively correlated with physical activity (r =00.32 p<0.05) and with ROSA (r= 0.24, p<0.05). Conclusions: In IT professionals, neck disability is associated with the lack of workspace ergonomics and the amount of physical activity. Forward head posture correlated with age, work experience, and poor workspace ergonomics. According to our findings, there are real concerns about the influence of head posture and workplace ergonomics on health among IT professionals. We consider that it is necessary to adopt preventive measures to address neck disability and improve workspace ergonomics.

Relationships Among Musculoskeletal Symptoms, Self-Rated Health, and Work Locations in Studies of Computer Work or Coronavirus Diagnosis

OBJECTIVE

To clarify work location's association with musculoskeletal symptoms.

METHODS

Study 1 surveyed 246 working adults who usually felt pain, in general, and increased pain from computer work. Study 2 surveyed a nationally representative sample of 1084 working adults.

RESULTS

In study 1, 32.5% of the participants sought treatment for their increased pain from computer work. Education differed by work location. When education was considered, there were no significant work location differences in pain intensity, pain interference, or self-rated health. In study 2, COVID-19 diagnoses, education, and gender differed by work location. Age and work location explained self-rated health. Self-rated health was associated with musculoskeletal ache. Work location did not significantly predict musculoskeletal ache.

CONCLUSION

Working at home was associated with fewer COVID-19 diagnoses and higher self-rated health than working at employers' locations.

Telework Conditions, Ergonomic and Psychosocial Risks, and Musculoskeletal Problems in the COVID-19 Pandemic

OBJECTIVE

To evaluate the association of telework conditions with ergonomic and psychosocial risks and with the occurrence of musculoskeletal problems among employees of the Brazilian Labor Judiciary during the COVID-19 pandemic.

METHODS

A cross-sectional study was conducted with 934 workers from August to October 2021. The data were collected via Web using a self-administrated questionnaire survey. Nonparametric tests and generalized linear regression analysis were used.

RESULTS

Previous experience in telework was associated with a better evaluation of the home workstation, a lower increase in workload, a greater increase in productivity, and greater preference to continue teleworking after the pandemic. The lack of a place dedicated to telework was specially related to greater ergonomic and psychosocial risks and to the greater occurrence of musculoskeletal problems.

CONCLUSIONS

Companies should monitor telework conditions to reduce health risks among their employees.

Home office versus ergonomic workstation - is the ergonomic risk increased when working at the dining table? An inertial motion capture based pilot study

Background

In order to reduce the risk of infection with Sars-Cov-2, work practices have been shifted to the home office in many industries. The first surveys concerning this shift indicate an increase in musculoskeletal complaints of many employees. The aim of this study was to compare the ergonomic risk in the upper extremities and trunk of working in a home office with that of working in an ergonomically optimized workplace.

Methods

For this purpose, 20 subjects (13w/7m) aged 18–31 years each performed a 20-minute workplace simulation (10 min writing a text, 10 min editing a questionnaire) in the following set up: on a dining table with dining chair and laptop (home office) and on an ergonomically adjusted workstation (ergonomically optimized workplace). The subjects were investigated using a combined application of a motion capture kinematic analysis and the rapid upper limb assessment (RULA) in order to identify differences in the ergonomic risk.

Results

Significantly reduced risk values for both shoulders (left: p < 0.001; right: p = 0.02) were found for the ergonomically optimized workstations. In contrast, the left wrist (p = 0.025) showed a significantly reduced ergonomic risk value for the home office workstation.

Conclusion

This study is the first study to compare the ergonomic risk between an ergonomically optimized workplace and a home office workstation. The results indicate minor differences in the upper extremities in favor of the ergonomically optimized workstation. Since work-related musculoskeletal complaints of the upper extremities are common among office workers, the use of an ergonomically optimized workstation for home use is recommended based on the results.

Perceived privacy in home office and musculoskeletal complaints: a test of family–work conflict, work–family conflict, and relaxation as mediators

Many employees have had to telework all year during the COVID-19 pandemic. Even though working from home has many advantages, there are also some disadvantages worth to consider. Lack of privacy is a relevant factor when it comes to the development of severe musculoskelatal issues. This study investigated the link between perceived privacy in home office and musculoskeletal complaints (MSCs). Family–work conflict (FWC), work–family conflict (WFC), and relaxation were tested as potential mediators for the relationship between perceived privacy and MSCs. The present study’s questionnaire was filled out by 287 teleworking employees. Hypotheses were tested via multiple mediation analyses examining levels of perceived privacy in home office, and its relationship on MSCs. Furthermore, the underlying effect of FWC, WFC, and MSCs were tested with a structural equation model. As assumed, lack of privacy while working at home was linked to individuals more frequently experiencing MSCs. However, the structural equation model showed no significant mediation effect. Work design efforts must address privacy while employees perform telework at home to prevent MSCs.

Working from home and productivity under the COVID-19 pandemic: Using survey data of four manufacturing firms

The coronavirus disease 2019 (COVID-19) pandemic has impacted the world economy in various ways. In particular, the drastic shift to telework has dramatically changed how people work. Whether the new style of working from home (WFH) will remain in our society highly depends on its effects on workers’ productivity. However, to the best of our knowledge, the effects of WFH on productivity are still unclear. By leveraging unique surveys conducted at four manufacturing firms in Japan, we assess within-company productivity differences between those who work from home and those who do not, along with identifying possible factors of productivity changes due to WFH. Our main findings are as follows. First, after ruling out the time-invariant component of individual productivity and separate trends specific to employee attributes, we find that workers who worked from home experienced productivity declines more than those who did not. Second, our analysis shows that poor WFH setups and communication difficulties are the major reasons for productivity losses. Third, we find that the mental health of workers who work from home is better than that of workers who are unable to work from home. Our result suggests that if appropriate investments in upgrading WFH setups and facilitating communication can be made, WFH may improve productivity by improving employees’ health and well-being.

Increased Working From Home in Vocational Counseling Psychologists During COVID-19: Associated Change in Productivity and Job Satisfaction

During the coronavirus disease 2019 (COVID-19) pandemic, vocational counselors in Switzerland more frequently worked from home (WFH) and less frequently worked on-site. The aim of this study was to assess how WFH corresponds with indicators of job performance and occupational wellbeing. More specifically, the current questionnaire study analyzed the increase in WFH, self-reported productivity, distractibility in WFH, current job satisfaction, work-life balance in WFH, and feeling of loneliness. Findings showed that the increase in WFH in vocational counseling psychologists during the COVID-19 pandemic was associated with an increase in productivity and job satisfaction and with lower distractibility in WFH compared to work on-site. However, more frequent WFH was not significantly associated with improved work-life balance during the COVID-19 pandemic. Vocational counselors who shared the office on-site with many colleagues experienced higher feeling of loneliness during WFH. Vocational counselors regarded the condition of WFH as productive and satisfying while work-life balance did not improve. The discussion sheds light on the potential WFH-related increase of boundary management demands.

COVID-19, the Built Environment, and Health

BACKGROUND

Since the dawn of cities, the built environment has both affected infectious disease transmission and evolved in response to infectious diseases. COVID-19 illustrates both dynamics. The pandemic presented an opportunity to implement health promotion and disease prevention strategies in numerous elements of the built environment.

OBJECTIVES

This commentary aims to identify features of the built environment that affect the risk of COVID-19 as well as to identify elements of the pandemic response with implications for the built environment (and, therefore, for long-term public health).

DISCUSSION

Built environment risk factors for COVID-19 transmission include crowding, poverty, and racism (as they manifest in housing and neighborhood features), poor indoor air circulation, and ambient air pollution. Potential long-term implications of COVID-19 for the built environment include changes in building design, increased teleworking, reconfigured streets, changing modes of travel, provision of parks and greenspace, and population shifts out of urban centers. Although it is too early to predict with confidence which of these responses may persist, identifying and monitoring them can help health professionals, architects, urban planners, and decision makers, as well as members of the public, optimize healthy built environments during and after recovery from the pandemic. https://doi.org/10.1289/EHP8888.
