Working From Home During a Pandemic: Investigation of the Impact of COVID-19 on Employee Health and Productivity

OBJECTIVE

To determine ergonomic problems when working from home during the COVID-19 pandemic with regard to musculoskeletal pain, sleep conditions, physical activity, resting, equipment, and productivity.

METHODS

In this cross-sectional study, office workers who switched to working from home during the COVID-19 pandemic participated in an online survey (n = 194). The data were interpreted using descriptive and multivariate regression analysis.

RESULTS

A significant increase in back pain was revealed (P < 0.001). Significant weight gain was observed (P < 0.001) connected to a decrease in physical activity and an increase in the consumption of junk food. Despite the negative health impact, participants self-reported an increase in productivity.

CONCLUSION

The self-reported productivity was higher during the working from home, but a declining trend in employee health can be observed including low back pain and weight gain.

State of science: the future of work - ergonomics and human factors contributions to the field

This article is concerned with scholarly ergonomics and human factors (E/HF) contributions to date to the field of research inquiry known as the 'future of work'. The review considers E/HF perspectives on how the nature of work is changing and what this means for the practice of E/HF and for human performance and wellbeing at work. This field of research has attracted much attention from scholars from various disciplines as flexible working arrangements and casualised employment, in particular, have come under the microscope during the COVID-19 pandemic. The article begins by setting out the future of work field, focussing on the mega trends and future of work forces that are most relevant to the discipline. Next, E/HF contributions to this field are identified and discussed. Surprisingly, given the E/HF tradition as a system discipline fundamentally concerned with the study of human work, and as a contributor to transdisciplinary research related to the design of work systems, a search of the scholarly literature found few contributions outside of the automation systems field that addressed the future of work and E/HF directly. A research agenda is presented to address gaps in current knowledge in a number of key future of work domains. Practitioner's Summary: We reflect on E/HF contributions to the 'future of work' field and how the practice of E/HF needs to consider the changing nature of work. We outline future of work concerns and suggest research areas for further E/HF attention towards the design of decent and sustainable work for all.

Posture during the use of electronic devices in people with chronic neck pain: A 3D motion analysis project

BACKGROUND

Non-neutral postures during computerised device use coupled with increased usage may increase the risk of neck pain. Greater knowledge of postures that individuals with neck pain adopt during computerised device use is warranted.

OBJECTIVE

To evaluate neck and upper limb posture while using a tablet, laptop and desktop computer (sitting and standing) in individuals with chronic neck pain.

METHODS

Differences in three-dimensional kinematic variables were assessed during four conditions: tablet, laptop, desktop computer (sitting and standing) in 22 individuals with chronic neck pain >3 months. Differences between kinematic variables were determined using one-way repeated measures ANOVA with Bonferroni post-hoc tests.

RESULTS

Compared to the desktop (sitting), tablet and laptop use resulted in increased neck flexion (mean difference tablet - 14.42°, 95% CI - 19.88, -8.96, P < 0.001; laptop -7.19°, -12.08, -2.31, P = .020); upper trunk flexion (tablet -14.89°, -20.22, -9.56, P < 0.001; laptop -5.56°, -10.02, -1.09, P = .009) and tablet bilateral shoulder elevation (left 11.01 mm, 2.01, 20.04, P < .016; right 13.08 mm, 3.09, 23.11, P < .006).

CONCLUSIONS

Tablet and laptop use resulted in greater neck flexion, bilateral shoulder elevation and upper trunk flexion compared to a standard desktop computer, suggesting individuals with chronic neck pain should be mindful of their posture when using these smaller devices. Future research should explore how differences in posture may influence neck pain.
