Abstract
Objective This study investigates the relationship of living environment factors with satisfaction, work engagement, perceived productivity, and stress among teleworkers. Background Given the increase in telecommuting since the onset of the pandemic, the study aims to identify how to create an optimum environment for telecommuting workers. Methods By examining the relationships among these factors via multiple regression analysis, a comprehensive investigation of the telecommuting working environment is conducted, encompassing physical aspects and facilities as well as lifestyle rhythms and relationships with housemates. In doing so, the author identifies measures to create a more favorable living environment. The work environment of remote workers is examined from various perspectives using the framework of the SHEL model: Software (work content, lifestyle, etc.), Hardware (furniture, equipment, etc.), Environment (indoor environment), and Liveware (relationships with family members who reside with the worker). Results The results suggest that positive factors, such as satisfaction and work engagement, are strongly influenced by the degree of job autonomy and the availability of a workspace dedicated to personal use. Negative aspects, such as stress, are significantly impacted by environmental noise, interruptions due to household tasks, and the use of ergonomic furniture.

Feige S, Holzgreve F, Fraeulin L, Maurer-Grubinger C, Betz W, Erbe C, Nienhaus A, Groneberg DA, Ohlendorf D. Ergonomic Analysis of Dental Work in Different Oral Quadrants: A Motion Capture Preliminary Study among Endodontists. Bioengineering (Basel) 2024; 11:400. [PMID: 38671821 PMCID: PMC11048138 DOI: 10.3390/bioengineering11040400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 04/12/2024] [Accepted: 04/15/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Dentists, including endodontists, frequently experience musculoskeletal disorders due to unfavourable working postures. Several measures are known to reduce the ergonomic risk; however, there are still gaps in the research, particularly in relation to dental work in the different oral regions (Quadrants 1-4). METHODS In this study (of a pilot character), a total of 15 dentists (8 male and 7 female) specialising in endodontics were measured while performing root canal treatments on a phantom head. These measurements took place in a laboratory setting using an inertial motion capture system. A slightly modified Rapid Upper Limb Assessment (RULA) coding system was employed for the analysis of kinematic data. The significance level was set at p = 0.05. RESULTS The ergonomic risk for the entire body was higher in the fourth quadrant than in the first quadrant for 80% of the endodontists and higher than in the second quadrant for 87%. For 87% of the endodontists, the ergonomic risk for the right side of the body was significantly higher in the fourth quadrant compared to the first and second quadrant. The right arm was stressed more in the lower jaw than in the upper jaw, and the neck also showed a greater ergonomic risk in the fourth quadrant compared to the first quadrant. CONCLUSION In summary, both the total RULA score and scores for the right- and lefthand sides of the body ranged between 5 and 6 out of a possible 7 points. Considering this considerable burden, heightened attention, especially to the fourth quadrant with a significantly higher ergonomic risk compared to Quadrants 1 and 2, may be warranted.

Bai Y, Kamarudin KM, Alli H. A systematic review of research on sitting and working furniture ergonomic from 2012 to 2022: Analysis of assessment approaches. Heliyon 2024; 10:e28384. [PMID: 38571611 PMCID: PMC10988004 DOI: 10.1016/j.heliyon.2024.e28384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 03/03/2024] [Accepted: 03/18/2024] [Indexed: 04/05/2024] Open
Abstract
This study analyses which aspects of sitting and working furniture ergonomics that may be influenced and how they are assessed. To gather information on the types and assessment techniques connected with influencing furniture ergonomics, a systematic review of the literature was conducted. The papers in the systematic review were published between 2012 and 2022. The articles applied the Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines to limit the 41 papers that were eventually included (N = 41) to those containing keywords like ergonomics, human factors, comfort, working furniture, Chair, assessment and evaluation. The research objective of this systematic review is to provide a comprehensive overview of sitting and working furniture and the main findings, obtaining common assessment techniques for this type of furniture and their suitability. According to the relevant studies, the publications were categorized by summarizing factors like region, gender, research methods, ergonomic assessment techniques and methods used, correlation between assessment techniques and methods, etc. Summaries of the data extracted from the included papers are provided and the applicability of some approaches are assessed. Only a small number of authors have evaluated the ergonomics of furniture used in homes. One of the research gaps is the paucity of research on gender segregation, secular trends, and cultural contexts. These studies heavily rely on quantitative research techniques, and the articles may lack credibility due to the homogeneity of the evaluation techniques. Finally, the authors offer some suggestions for the appropriate ergonomic analysis of furniture.

Garcia MG. Perceived Physical Discomfort and Its Associations With Home Office Characteristics During the COVID-19 Pandemic. HUMAN FACTORS 2024; 66:916-932. [PMID: 35758896 PMCID: PMC9243971 DOI: 10.1177/00187208221110683] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Accepted: 06/07/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE The goal of this study was to evaluate the prevalence and change in perception of physical discomfort, including musculoskeletal discomfort, during the COVID-19 pandemic and to determine associations of demographic factors, telework activity, and home office characteristics with the highest prevalence of discomfort. BACKGROUND The COVID-19 pandemic forced a substantial increase in telework in many countries. The sudden change from a regular workplace to an improvised "home office" may have an impact on working conditions and physical symptoms of office workers. However, investigations in this area remain limited. METHOD A cross-sectional study design was used to compare self-reported complaints of physical discomfort perceived from before with those during the pandemic. Associations between complaints and home office characteristics were investigated from 150 faculty and 51 administrative staff of an academic institution with an age range of 41.16 ± 10.20 (59% female). RESULTS A significant increase of physical discomfort was found during the pandemic period for head, eyes, hand, and upper back for both staff and faculty and neck, shoulders, elbows, and lower back for faculty only. Logistic regression analyses point to associations with the lack of a laptop stand, uncomfortable desk, poor lighting, and sitting time, among others. CONCLUSION A high prevalence of physical discomfort was reported by teleworkers during the COVID-19 pandemic. Some home office characteristics were associated with these discomforts. APPLICATION Some telework characteristics seem to be risk factors for physical discomfort. Consideration should be given to teaching best practices for workstation setup and/or conducting other preventive interventions in the work environment.

Abstract
Remote e-working with information and communication technology (ICT) has long been on the rise, with its implementation accelerated by mandatory working from home regulations during the COVID-19 pandemic. This systematic literature review summarises the influencing factors of ICT-based remote e-working (device types, duration of use, user interfaces, etc.) on the physical health (musculoskeletal system and eyes) of knowledge workers. A search in four electronic databases and a manual search in four German journals resulted in 21 articles being included in this review. A bias analysis was conducted for all articles. Unfavourable postures, inappropriate working devices and certain environmental factors may cause a range of physical complaints, even after comparably short periods of time. Mostly, these complaints are greater compared to those experienced when working on a fully equipped stationary computer. Therefore, remote e-working requires careful planning, awareness, and the willingness to embrace working situations that counteract these problems.

Abstract
The aim of this randomized controlled study was to explore if an intervention with biofeedback training in combination with ergonomic discussions, could improve working technique and work postures, and reduce pain intensity and perceived exertion in young adult computer users with ongoing neck and upper extremity symptoms. 39 participants were divided into an intervention group and a control group. The intervention consisted of 4 sessions during a three-month period. Working technique, working postures, rated perceived exertion, pain intensity, and duration of computer use were measured at baseline and follow ups after 6 and 12 months. The intervention did not significantly improve working technique and working postures, nor reduce pain intensity and perceived exertion in the intervention group compared to the control group. However, there was a statistically significant reduction in reported pain intensity in the neck/shoulder for the whole group. Also, there was a trend that time spent with computer work without breaks was more reduced in the intervention group than in the control group.

Abstract
BACKGROUND Musculoskeletal complaints (MSCs) may be more common in individuals with brachial plexus injury (BPI), whose physical work demands exceed their functional capacity (FC). OBJECTIVES (a) To assess the concurrent validity of five methods for measuring upper extremity work demands and the Dictionary of Occupational Titles (DOT). (b) To explore the relations between MSCs, physical work demands, and FC in individuals with BPI. METHODS This study had a descriptive correlational design. Physical work demands of 16 individuals with BPI (12 males, 6 one-handed workers) were assessed during work using five assessment methods and the DOT. Spearman correlation coefficients between work demand methods were determined. FC was assessed using the functional capacity evaluation one-handed (FCE-OH). A questionnaire was used to examine MSCs. The relationship between MSCs, physical work demands and FC was analyzed visually, using Spearman correlation coefficients, and by comparing FCE-OH results to FCE reference values. RESULTS Spearman correlation coefficients for the DOT and four out of five assessment methods for determining work demands on upper extremities were significant and moderate (four combinations: r = 0.65-0.79) to strong (five combinations: r = 0.81-0.94). Correlations of the fifth method with the other methods were weak to fair. No significant relationships were found between MSCs, physical work demands and FCE-OH results. CONCLUSION The relationships between MSCs, physical work demands, and FC are evidently complex and require further investigation. In this small sample the concurrent validity of the DOT and four methods for determining work demands on upper extremities was moderate to good.

Abstract
OBJECTIVE Evaluate the effects of 10 min/day of yoga for 1 month on musculoskeletal discomfort and mood disturbance of home-office workers. BACKGROUND The COVID-19 pandemic forced many people to switch to teleworking. The abrupt change from an office setting to an improvised home-office may negatively affect the musculoskeletal and emotional health of workers. By providing mental and physical exercises, yoga may be effective in reducing adverse effects. METHOD Fifty-four participants (42 women, 12 men) followed a 1-month yoga program, while 40 participants (26 women, 14 men) continued with their common work routine. The Cornell Musculoskeletal Discomfort Questionnaire was used to evaluate severity, interference with work and frequency of pain, and to obtain a total discomfort score for 25 body areas. Mood disturbance was evaluated with the Profile of Mood States questionnaire. Both groups completed both questionnaires, before and after the experimentation period. RESULTS After 1 month, for the yoga group only, significant reductions were observed in the discomfort of eyes, head, neck, upper and lower back, right wrist, and hips/buttocks, as well as reductions in discomfort severity, frequency and interference for the neck, upper and lower back. Total mood disturbance was also significantly reduced for the yoga group only. No favorable changes occurred for the control group. CONCLUSION The yoga intervention program appears to reduce musculoskeletal discomfort and mood disturbance of home-office workers. APPLICATION Sedentary workers may benefit from 10 min/day of yoga during the workday to attenuate potential physical and emotional discomfort during the current pandemic and beyond.

Abstract
BACKGROUND The COVID-19 pandemic resulted in unprecedented restrictions on public and private life. The aim of the study was to investigate the impact of the COVID-19 pandemic on the physical and mental health of employees in the public sector, especially patient-related professions. METHODS For the data collection in summer 2021, an online questionnaire was used. Compared to a pre-pandemic point of time, the prevalence, frequency, and intensity of musculoskeletal pain, mental well-being, health status, and quality of life were recorded. RESULTS The questionnaire was completed by 1678 employees (f: 1045, m: 617). A total of 1504 employees (89.6%) were affected by complaints. Compared to before the pandemic, the prevalence and intensity of musculoskeletal complaints and psychological distress increased significantly. Patient-related professions (n = 204) showed significantly higher levels of stress and discomfort in several aspects (p < 0.05). CONCLUSIONS Due to the COVID-19 pandemic, there was an increase in musculoskeletal complaints and a decrease in psychological well-being. Preventive factors related to mental health were identified as male gender, a middle- to older-age group, employees with children, and working from home. Attention should be drawn to these findings and prevention strategies should be brought into focus to strengthen the employees' health. Special focus should be drawn to patient-related professions who are particularly confronted with pandemic-associated challenges.

Abstract
Background and objective Shoulder pain stands out as the most prevalent musculoskeletal issue that office workers face. This type of pain has been observed to be linked to various aspects of one's job. To address this concern, the current research endeavors to examine the impact of digital device use on the intensity of shoulder pain and the extent of disability experienced by office employees in Saudi Arabia. This study is driven by two principal objectives. Firstly, it aims to assess the overall occurrence of shoulder discomfort and functional limitations among the Saudi office worker population. Secondly, it seeks to draw comparisons between the parameters of the shoulder pain and disability scale and the amount of time spent using electronic screens. Methodology This cross-sectional descriptive study was conducted in Riyadh, Saudi Arabia. We recruited 150 participants to measure shoulder pain and disability among office workers. The study was carried out to determine the general frequency of shoulder discomfort and impairment by using the Shoulder Pain and Disability Index (SPADI). The survey was conducted online in June 2022 via Google Forms. The survey questions included data regarding age, sex, year of study, exercise, and duration of computer time per day (hours). Results This study recruited 150 participants to measure shoulder pain and disability among office workers. The mean age of the cohort was 42.56 ± 2.56 years. Among the total participants, 90 (60%) were male, and 60 (40%) were female. We observed that pain parameters had a negative correlation of -0.008 with screen time. The participants who had high shoulder pain and disability scores were older in age and spent less than two hours on screens, which affects the correlation results, and hence we recommend performing a study involving the younger population working on screen for more than four hours to find the better correlation. At the same time, the shoulder disability score reported a correlation of 0.05, and the overall correlation between SPADI and screen time was observed to be 0.04. Based on these findings, the present study observed a weak correlation between SPADI and screen time. Conclusion These results suggest that while there may be some association between screen time and shoulder pain and disability, it is not substantial. Therefore, it is unlikely that screen time alone significantly contributes to the occurrence or severity of shoulder pain and disability among office workers. Additional factors and variables may need to be explored in future research to gain a more comprehensive understanding of this issue.

Biomechanical Assessments of the Upper Limb for Determining Fatigue, Strain and Effort from the Laboratory to the Industrial Working Place: A Systematic Review. Bioengineering (Basel) 2023; 10:bioengineering10040445. [PMID: 37106632 PMCID: PMC10135542 DOI: 10.3390/bioengineering10040445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 03/24/2023] [Accepted: 04/03/2023] [Indexed: 04/08/2023] Open
Abstract
Recent human-centered developments in the industrial field (Industry 5.0) lead companies and stakeholders to ensure the wellbeing of their workers with assessments of upper limb performance in the workplace, with the aim of reducing work-related diseases and improving awareness of the physical status of workers, by assessing motor performance, fatigue, strain and effort. Such approaches are usually developed in laboratories and only at times they are translated to on-field applications; few studies summarized common practices for the assessments. Therefore, our aim is to review the current state-of-the-art approaches used for the assessment of fatigue, strain and effort in working scenarios and to analyze in detail the differences between studies that take place in the laboratory and in the workplace, in order to give insights on future trends and directions. A systematic review of the studies aimed at evaluating the motor performance, fatigue, strain and effort of the upper limb targeting working scenarios is presented. A total of 1375 articles were found in scientific databases and 288 were analyzed. About half of the scientific articles are focused on laboratory pilot studies investigating effort and fatigue in laboratories, while the other half are set in working places. Our results showed that assessing upper limb biomechanics is quite common in the field, but it is mostly performed with instrumental assessments in laboratory studies, while questionnaires and scales are preferred in working places. Future directions may be oriented towards multi-domain approaches able to exploit the potential of combined analyses, exploitation of instrumental approaches in workplace, targeting a wider range of people and implementing more structured trials to translate pilot studies to real practice.

Abstract
BACKGROUND The coronavirus 2019 (COVID-19) pandemic acts as a recent driver for telework on a global scale. While visual display unit (VDU) workplaces are usually subject to regulatory requirements or occupational health and safety controls, mobile workplaces may increase the risk of developing work-related musculoskeletal complaints (MSCs). OBJECTIVE This study aimed to explore the influence of work from home (WFH) on musculoskeletal complaints in the context of German municipal administrations. METHODS This paper is based on an online survey conducted as part of the Health and Digital Change project in cooperation with three municipal administrations in North Rhine-Westphalia, Germany. A multivariate model was constructed to calculate the odds ratio for MSCs including various control variables. RESULTS While bivariate analysis showed a 0.96-fold risk for employees who work from home, the multivariate model with a split between occasional (OR = 0.79) and frequent (OR = 1.59) WFH revealed a more complex effect. Both odds did not reach the significance level. However, the influence of being female (OR = 3.34) and being overweight (OR = 1.51) was confirmed. Regarding age the OR increases by 1.02 per year of life. Other control variables were the municipal affiliation, university entrance qualification, working hours and feeling overstrained. The regression model improved by 0.07 (McFadden R2) compared to the null model. CONCLUSION Although WFH is discussed as a rising risk factor for MSCs, the findings in this study indicate, that occasional WFH acts as a rather protective factor against work related MSCs.

Abstract
BACKGROUND Office workers are at high risk of developing musculoskeletal symptoms (MSS) due to improper workstations. Open-plan bank office employees must communicate with bank clerks properly and perform financial activity precisely, but noise is a factor that disrupts their communication. Therefore, MSS and annoying noise are two of the main problems in open-plan offices. OBJECTIVE This study evaluated the effects of a multi-component intervention involving individual (employee ergonomics training) and physical (improvements in workstation design and work environment) ergonomic factors on musculoskeletal outcomes and speech communication in open-plan environments. METHODS A preliminary survey was carried out to investigate the overall ergonomics problems, the tasks and time analysis, workstations setup, the prevalence of MSS (Nordic Musculoskeletal Questionnaire), physical discomfort (Visual Analogue Scale [VAS]), and posture (assessed by Rapid Upper Limb Assessment [RULA] method), environmental status (measurement of noise), and speech intelligibility (assessed by Speech Interference Level [SIL] method based on ISO 9921). The multi-component interventions were performed afterward based on the data collected. A baseline assessment and a 9-month follow-up assessment were conducted. RESULTS The results showed a significant decrease in the prevalence of musculoskeletal complaints (shoulders, elbows, and low back), physical discomfort, and awkward working postures after the intervention. A considerable improvement was also found in speech intelligibility post-intervention. The post-intervention questionnaire survey also indicated that employees generally favored the redesigned workstations. CONCLUSION The results support the effectiveness of implementing multi-component interventions in open-plan bank offices to improve musculoskeletal complaints and speech communication.

Abstract
BACKGROUND Using a laptop for work is gaining rapid popularity, but there is little evidence of how it influences musculoskeletal disorders (MSDs) and functional characteristics of the neck and shoulder area. OBJECTIVE This study aimed to compare the prevalence of upper body MSDs and functional characteristics of the neck between office workers using a laptop or desktop computer. METHODS A total of 110 office workers with a mean age of 41±10 years participated. 45 office workers (73% female) used a laptop and 65 office workers (86% female) used desktop computers. The prevalence of MSDs was recorded using the Nordic Musculoskeletal Questionnaire. Active range of motion (AROM), maximal voluntary isometric contraction (MVC) force, joint position error (JPE), and pain-pressure threshold (PPT) of the neck and shoulder area were measured. RESULTS Laptop users experienced significantly more MSDs in the right shoulder area on the day of participation (p < 0.001, OR = 4.47), during the previous 7 days (p < 0.01, OR = 3.74), and at 6 months (p < 0.01, OR = 3.57). Laptop users also experienced significantly more MSDs in the left shoulder during the previous 7 days (p < 0.05, OR = 2.44). There were no statistically significant differences in any of the functional characteristics of the neck and shoulder area between the groups. CONCLUSION Using the laptop computer for office work may pose a higher risk of developing MSDs in the right shoulder area, but might not have long-term effects on the functional characteristics of the neck and shoulder area.

Abstract
BACKGROUND Practicing incorrect postures in online and virtual education during the COVID-19 pandemic can cause significant study-related musculoskeletal problems among students. OBJECTIVE This study evaluated the knowledge, attitude, and practice of sitting posture and computer ergonomics and study-related musculoskeletal problems in undergraduates who followed online education during the pandemic. METHODS A cross-sectional online survey among a cohort of Sri Lankan medical undergraduates was conducted using a structured questionnaire with 56 multiple-choice or Yes/No type questions. RESULTS Of the 410 participants, over 85% (n = 362) knew the correct posture to sit on the chair type that they frequently used for studies. However, the majority (n = 378,92.20%) practised incorrect sitting postures in which leaning forward (n = 319,77.80%) was the most common suboptimal posture. Knowledge (n = 161,40%) and practice (n = 167,40.73%) on taking frequent breaks were poor among the majority. Their knowledge on computer ergonomics was good (>80%, n = 304) except for the recommended eye-to-screen distance (n = 129,31.46%). Importantly, ∼50% (n = 206) did not practise the recommended eye-to-screen distance. Use of non-adjustable chairs with no armrests (n = 346,84.39%) and smartphones (n = 354,86.34%) were identified as the main factors which hindered correct practices. Study-related pain/discomfort reported by the majority (n = 241,58.78%) is potentially due to suboptimal ergonomics. Their attitude toward learning and practicing correct ergonomics in home workstations was good (n = 383,93.41%). CONCLUSION Poor practice of posture and computer ergonomics, despite the good knowledge and attitude is possibly due to the suboptimal work environments. Introducing simple practical measures to facilitate ergonomically appropriate work environments is mandatory in virtual education to prevent study-related musculoskeletal problems.

Abstract
OBJECTIVE This study investigates the associations between working from home and the presence of MSP during the COVID-19 pandemic. Working from home often involves a lot of sedentary computer screen work and the home working environment might not be optimally equipped, which can lead to health problems, including musculoskeletal pain (MSP). METHODS Longitudinal data from 16 questionnaire rounds of the Lifelines COVID-19 cohort during the first year of the COVID-19 pandemic (March 2020-February 2021) were used. In total, 40,702 Dutch workers were included. In every round, participants reported whether they worked on location, from home, or hybrid. Logistic Generalized Estimating Equations were used to study the association of work situation with the presence of MSP and the presence of severe MSP. RESULTS Working from home was associated with higher risks of having MSP in the lower back (OR: 1.05, 95% CI 1.02-1.08), in the upper back (OR: 1.24, 95% CI 1.18-1.31), and in the neck, shoulder(s) and/or arm(s) (OR: 1.18, 95% CI 1.13-1.22). Hybrid working was associated with higher risks of having pain in the upper back (OR: 1.09, 95% CI 1.02-1.17) and in the neck, shoulder(s) and/or arm(s) (OR: 1.14, 95% CI 1.09-1.20). Both home and hybrid workers had higher risks of severe MSP in the different body areas. CONCLUSION Home workers, and to a smaller extent hybrid workers, had higher risks of having MSP than location workers during the first year of the COVID-19 pandemic. The results indicate the importance of measures to prevent MSP in future policies involving working from home.

Abstract
Background As a part of the coronavirus disease 2019 (COVID-19) lockdown measures, universities converted courses to digital formats, leading to remote studying. It is unclear how these measures affect university students in terms of musculoskeletal problems (i.e., neck and back pain), e.g., by non-ergonomically equipped home offices or reduced physical activity. Material and methods Students from Osnabrück University weresurveyed via fully standardized online questionnaires from early March to mid-April 2022 (6 weeks) about neck and back problems, movement behavior in home offices, and personal information. Results Of 447 students who clicked on the link, 378 students (80.4% female, mean age: 24.1 ± 4.2 years) answered the questionnaire (response rate: 84.6%). 299 (79.1%) students suffered from neck pain and 294 (77.8%) from back pain during the pandemic. 206 (54.4%) students generally used ergonomic furniture, 83 (22.0%) used ergonomic sitting furniture, 57 (15.1%) used a standing desk, and 212 (56.1%) used aids for a more comfortable use of laptops in home office. 203 (53.7%) students took movement breaks in home office, 207 (54.8%) worked out regularly, and 65 (17.2%) moved regularly in the fresh air. Conclusions The present study found a high rate of neck and back pain amongst university students. Measures are needed to prevent neck and back pain in this group, considering that increased physical activity and enhanced home office equipment might be beneficial.

Abstract
Background Musculoskeletal disorders (MSDs) are critical occupational and social problems. With the improvement of production mechanization and automation, and the widespread application of computers, more occupations are exposed to static postures and load. This study explored the role of inflammation in the association between static postures exposure and MSDs. Methods This study adopted a prospective nested case-control design in which 66 lower back MSDs cases and 66 healthy controls were selected from a cohort study of university employees. The personal information, postural load, musculoskeletal symptoms, pressure pain thresholds (PPTs), and inflammatory cytokines were collected. Logistic and linear regressions were used to investigate the association among postural load, inflammatory cytokines, and lower back MSDs. Mediation analysis was used to calculate the mediation effect. Results The results of logistic and linear regressions showed that postural load and inflammatory cytokines were positively associated with lower back MSDs (P < 0.05), and postural load was positively associated with inflammatory cytokines (P < 0.05). Further, mediation analysis showed that the mediation effect of postural load on the lower back MSDs through TNF-α was 0.073 (95%CI: 0.025-0.128), and the mediation effect of posture load on the lower back MSDs through IL-6 was 0.098 (95%CI: 0.041-0.179), respectively. Conclusion Static postures were associated with the occurrence of MSDs through inflammatory cytokines, and low-level inflammation may be a critical early event in the generation of MSDs. This study may help bridge the gap of potential mechanisms linking static postures to increased risks of MSDs, and provide new evidence for targeted protection against the global increasing MSDs.

Abstract
Abstract
Background
Office employees are at a greater risk for musculoskeletal disorders (MSD) due to their prolonged computer use. In the context of COVID-19, an unanticipated shift to working from home is likely to increase MSD due to a lack of an ergonomic workspace and longer workdays.
Aim
To explore the prevalence of MSD with work-related risk factors among the computer users working from home during the COVID-19 pandemic.
Study design
Cross-sectional survey.
Methods
Computer users working from home for more than 6 hours per day during the COVID-19 lockdown were assessed for possible work-related MSD using web-based survey—Google forms for Nordic Musculoskeletal Questionnaire.
Results
One hundred twenty one responses from 53 (43.8%) females (25.47 ± 5.72 years) and 68 (56.2%) males (28.65 ± 4.68 years) were included. The female participants were more prone to musculoskeletal pain as compared to males. The neck pain (60.3%), lower back pain (59.5%), and shoulder pain (49.6%) were the most reported body regions affected by work-related MSD. The elbow (18.2%), wrist/hand (35.5%), upper back (42.1%), hips (24.8%), knee (23.1%), and ankle/feet (14%) were the least affected regions. The risk factors associated with MSP includes lack of workplace at home during lockdown, stress after being in one posture, stress in eyes, and mental stress due to work.
Conclusions
During the lockdown phase, the transition of computer workers from working office environment to home increased the prevalence of MSD more commonly in females than males. There is a need to investigate early detection, prevention, and management options to enhance health outcomes.

Abstract
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.

Abstract
Different tools for the assessment of posture exist, from the simplest and cheap plumb line to complex, expensive, 3D-marker-based systems. The aim of this study is to present digital postural normative data of young adults collected through a mobile app to expand the possibilities of digital postural evaluation. A sample of 100 healthy volunteers, 50 males and 50 females, was analyzed with the mobile app Apecs-AI Posture Evaluation and Correction System® (Apecs). The Student’s t-test evaluated differences between gender to highlight if the digital posture evaluation may differ between groups. A significant difference was present in the anterior coronal plane for axillary alignment (p = 0.04), trunk inclination (p = 0.03), and knee alignment (p = 0.01). Head inclination (p = 0.04), tibia shift (p = 0.01), and foot angle (p < 0.001) presented significant differences in the sagittal plane, while there were no significant differences in the posterior coronal plane. The intraclass correlation coefficient (ICC) was considered to evaluate reproducibility. Thirteen parameters out of twenty-two provided an ICC > 0.90, three provided an ICC > 0.60, and six variables did not meet the cut-off criteria. The results highlight that digital posture analysis of healthy individuals may present slight differences related to gender. Additionally, the mobile app showed good reproducibility according to ICC. Digital postural assessment with Apecs could represent a quick method for preventing screening in the general population. Therefore, clinicians should consider this app’s worth as an auxiliary posture evaluation tool.

Abstract
BACKGROUND: Studies have suggested an association between computer work and the development of musculoskeletal disorders. However, studies examining the workplace ergonomics assessment of computer offices are scarce in the Pakistani population. OBJECTIVE: To determine the presence of ergonomic risk factors in the office using the Rapid Assessment Office Strain (ROSA) method for complaints of arm, neck and shoulder (CANS) among office computer workers. METHODS: From January to August 2019, a cross-sectional study was carried out among office workers who worked at least three hours on computers in their daily work. The prevalence of CANS was measured by using the Maastricht Upper Extremity Questionnaire (MUEQ) and work station evaluation was done by using Rapid Office Strain Assessment (ROSA). Data were collected from 773 computer workers, of whom 443 (56%) worked in the information technology sector, 215 (28%) in industry and 124 (16%) in universities. SPSS version 20 was used for data entry and analysis. RESULTS: Out of 773 computer workers, 448 (58%) reported musculoskeletal pain and the most prevalent were shoulder pain (327, 42%) and neck pain (270, 35%). The mean scores of ROSA sections A, B, C and D were 4.00±0.82, 2.98±0.72, 3.49±0.67 and 3.61±0.72 respectively. The mean ROSA total score in 773 office computer workers was 4.19±0.78, which indicates a low risk of musculoskeletal complaints. There was significant association was found between ROSA section A and shoulder pain (P = 0.043), ROSA section C with complaints of lower arm (P = 0.013), wrist (P = 0.016), and hand pain (P = 0.005), ROSA section D with lower arm (P = 0.002), wrist (P = 0.004) and hand complaints (P = 0.002). A significant association was found between ROSA total score and complaints of shoulder and hand, with p values of 0.012 and 0.006, respectively. CONCLUSION: CANS are prevalent among computer office workers, and there is a significant relationship between CANS and workstation ergonomics.

Abstract
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.

Abstract
AbstractObjectives. The aim of this study was to evaluate the ergonomic and psychosocial risks in telework and their relationship with musculoskeletal problems in Brazilian labor judges during the COVID-19 pandemic. Methods. A cross-sectional study was conducted with 119 participants. The data were collected through a sociodemographic and occupational questionnaire, from the Brazilian versions of the Maastricht Upper Extremity Questionnaire (MUEQ-Br revised), the Rapid Office Strain Assessment (ROSA-Br) and the Nordic Musculoskeletal Questionnaire (NMQ), added to a numerical pain scale. Results. According to ROSA-Br, 47.06% of the participants showed an outcome where it is considered that there is a need for immediate intervention in the workplace. The results of ROSA-Br and MUEQ-Br revised presented a significant correlation with the intensity of complaints in the neck and shoulders in the last 12 months and in the last seven days. The total score of MUEQ-Br revised presented more important correlations with problems in these body regions and with the intensity of complaints in the upper back, wrists/hands and lower back in both periods. Conclusions. Companies should propose ways to assess the ergonomic and psychosocial risks among their employees in telework as a way to prevent the occurrence of musculoskeletal problems.

Abstract
Background Most ergonomics studies on office workstations evaluate the effects of an intervention only by subjective measures such as musculoskeletal pain and discomfort. Limited evidence has been provided regarding risk factor reduction in office environments through standardized methods assessments. The Rapid Office Strain Assessment (ROSA) tool can provide an estimation of risk factor exposure for office workers as a means by which the outcome of interventions can be quantified. Purpose The aim of the study was to evaluate if ROSA scores reflect changes in risk factors after an ergonomics intervention among office workers. Methods Office workers (n = 60) were divided into two groups. The experimental group received a workstation intervention and the control group received no intervention. Changes in ROSA scores were compared before and after the intervention in both groups. Results Statistically significant reductions in the ROSA final and section scores occurred after the intervention in the experimental group with (mean reduction of 2.9, 0.8 and 1.6 points for sections A, B and C, respectively). In contrast, no differences were detected in the control group (mean increase of 0.1 point for sections A and C and mean reduction of 0.1 point for Section B). Conclusions These findings show that ROSA scores reflect changes in risk factors after an ergonomics intervention in an office environment. Consequently, this tool can be used for identifying and controlling risk factors among computer workers, before and after interventions.

Abstract
Musculoskeletal disorders (MSDs) of the upper extremities and computer use are common in modern societies, and both show a growing trend. This study was conducted to determine the posture and 3D moments of wrist and elbow joints at different keyboard distances on a desk. Twelve healthy right-handed male volunteers attended the motion analysis laboratory. A keyboard was placed at three different distances from the participants’ bodies while performing a standard computer task. The workstation was adjusted according to ANSI/HFES-100-2007 standard for each participant to maintain a comfortable ergonomic posture for controlling confounding variables. Qualisys motion capture system, OpenSim (Ver. 4.1), and visual analog scale were used to collect and analyze the data. The highest levels of wrist flexion and radial deviation as well as elbow flexion and pronation were observed when the keyboard was at the edge of the desk. When the keyboard was 8 cm away from the edge of the desk, the right wrist flexion and radial deviation decreased 83% and 89%, respectively. In the left wrist, flexion and radial deviation decreased 94%. With increasing the distance of the keyboard from the edge of the desk, the right elbow flexion, pronation, and left elbow flexion decreased, 95%, 76%, and 85%, respectively. No significant difference was found for the left elbow pronation, wrist, and elbow joint moments, in the studied keyboard distances. However, a cut-off point has to be specified because large keyboard distances cause high extension and flexion of the limbs. The keyboard position relative to the body is an important parameter in computer work and has a significant impact on the posture of the upper extremities. A keyboard should be located at a distance that allows the upper extremities to remain in a neutral position so that the risk of MSDs is reduced.

Abstract
BACKGROUND The recent mandate for university faculty and staff to work-from-home (WFH) during the COVID-19 pandemic has forced employees to work with sub-optimal ergonomic workstations that may change their musculoskeletal discomfort and pain. As women report more work-related musculoskeletal discomfort (WMSD), this effect may be exacerbated in women. OBJECTIVE The purpose of this study was to describe university employee at-home office workstations, and explore if at-home workstation design mediates the effect of gender on musculoskeletal pain. METHODS University employees completed a survey that focused on the WFH environment, at home workstation design and musculoskeletal pain. Descriptive statistics and regression analysis were used to analyze the responses. RESULTS 61% of respondents reported an increase in musculoskeletal pain, with the neck, shoulders and lower back being reported most frequently. Women reported significantly greater musculoskeletal pain, but this relationship was significantly mediated by poor ergonomic design of the home workstation. Improper seat-height and monitor distance were statistically associated with total-body WMSD. CONCLUSIONS WFH has worsened employee musculoskeletal health and the ergonomic gap between women and men in the workspace has persisted in the WFH environment, with seat height and monitor distance being identified as significant predictors of discomfort/pain.

Abstract
BACKGROUND The imposition of telework by the COVID-19 pandemic represented a challenge for companies and workers with regard to the management and organization of the workplace at home. OBJECTIVES To evaluate the ergonomic risks, psychosocial factors and musculoskeletal symptoms as well as the relationships between these variables in employees of a Brazilian labor judiciary unit. METHODS A cross-sectional study was carried out with 55 employees who had their workstations evaluated by means of the Rapid Office Strain Assessment (ROSA-Br) and answered a questionnaire of sociodemographic and occupational characterization, the dimensions of workstation and posture of the Maastricht Upper Extremity Questionnaire (MUEQ-Br-revised), the short version of the Job Stress Scale and the Nordic Musculoskeletal Questionnaire (NMQ). RESULTS The workstations evaluations by ROSA-Br and MUEQ-Br-revised showed a strong correlation between themselves and to body posture, but they were not related to the occurrence of musculoskeletal symptoms. Body posture and demands were correlated to each other and with to occurrence of musculoskeletal symptoms. Shoulders, neck and wrists / hands were the most affected body regions. CONCLUSIONS Companies that adopt teleworking for their employees must be aware of working conditions at home, including the workload, and offer adequate support in order to prevent the occurrence of musculoskeletal problems.

Abstract
BACKGROUND Computer-intensive office work associations with health challenges may intensify following COVID-19 pandemic-related changes to home-based office work. OBJECTIVE To determine working conditions, perception and physical elements affecting health after pivoting to full time home-work. METHODS An online questionnaire addressed physical, productivity, motivation, and work-practice factors. Photos of the worker in their home-work environment showed side and front-back perspectives. RESULTS Sixteen questionnaires were received, and 12 respondents supplied photos. Home and office workplace differences varied. Ten felt productivity was affected, most often positively. Four noted increased pain or fatigue intensity, particularly in the eyes, neck / head, lower back, and shoulders. Working posture was not optimal; six didn't use traditional chair-sitting for up to half the day. Forward and backward trunk inclination accounted for at least 10% of the workday for 12 respondents; lateral inclination affected ten and eight had unsupported legs. Fifteen used an adjustable chair, but photos revealed ergonomic recommendations were not consistently followed. Fourteen participants communicated regularly by telephone, eight only for moderate duration and ten using adapted telephone equipment. Half of the ROSA scores were high. CONCLUSIONS Workers forced into telework during the pandemic experience positive and negative impacts. Postures vary more than in offices, potentially increasing health risk.

Abstract
The objectives of this study are to investigate building professionals' experience, awareness, and interest in occupant health in buildings, and to assess the impact of the COVID-19 pandemic on their opinions, as well as to compare the research on occupant health in buildings to professionals' opinions. To address these objectives, a mixed research methodology, including a thorough review of the literature (NL = 190) and an online survey (NS = 274), was utilized. In general, there is an increasing research interest in occupant health and a heightened interest in health-related projects, among professionals, following the COVID-19 pandemic. Specifically, among the nine different building attributes examined, indoor air quality was the most researched building attribute with a focus on occupant health and was also presumed to be the most important by the professionals. Professionals considered fatigue and musculoskeletal pain to be the most important physical well-being issues, and stress, anxiety, and depression to be the most important mental well-being issues that need to be the focus of design, construction, and operation of buildings to support and promote occupant health, while eye-related symptoms and loss of concentration were the most researched physical and mental well-being symptoms in the literature, respectively. Finally, professionals indicated that COVID-19 pandemic had significant effect on their perspectives regarding buildings' impact on occupant health and they believed future building design, construction and operation will focus more on occupant health because of the pandemic experience.

Abstract
BACKGROUND Nowadays, although using laptops to perform many routine activities is inevitable, many wheelchair users are not able to efficiently use their laptops due to their movement limitations and inappropriate workstations. OBJECTIVE The purpose of this study was to design and evaluate a novel ergonomic laptop desk for wheelchair users by considering their movement limitations. METHODS In this experimental study, we ergonomically designed and assessed a novel laptop desk in two phases in a laboratory. In the first phase of the study, design specifications were identified by an expert panel; accordingly, a new laptop desk was designed and prototyped for the wheelchair users. In the second phase, in order to evaluate the laptop desk, 14 wheelchair users were asked to complete a typing task within 20 minutes, both with and without using the laptop desk. Postural risk level, perceived discomfort, and task performance were evaluated using the Rapid Upper Limb Assessment (RULA) technique, Local Perceived Discomfort (LPD) questionnaire, and the number of letters typed and typing errors, respectively. RESULTS The postures of the wrist, arm, and neck regions were corrected from RULA action level 3 to 2 when the designed laptop desk was used. In addition, the average perceived discomfort of the participants significantly decreased in the neck, shoulder, and wrist regions. Furthermore, typing accuracy was improved significantly when novel laptop desk was used. CONCLUSIONS Accommodating wheelchair user's workstation with the novel designed laptop desk could reduce musculoskeletal disorders risk factors and help wheelchair users to perform their work more efficiently.

Abstract
Background Telework has been widely discussed in several fields; however, there is a lack of research on the health aspects of teleworking. The current study was conducted to determine the health effects of teleworking during an emergency statement as evidence for future policy development. Method This was a cross-sectional study in which we administered an online questionnaire to 5,214 general workers (response rate = 36.4%) from June 2020 to August 2020. Based on working methods during the pandemic, workers were categorized into the office group (n = 86) and telework group (n = 1597), and we characterized their demographics, changes in lifestyle, telework status, physical symptoms, and mental health. Results The results showed that the workers’ residence, marital status, management positions, and employee status affected the choice of the work method. During the emergency, teleworkers experienced more changes in their habits than office workers. In terms of exercise habits, 67.0% of the individuals belonging to the office-telework (OT) group exercised less. Approximately half of the teleworkers were satisfied with their telework, and those in the OT group were less satisfied with their telework than those in the telework-telework (TT) group, and they reported an increase in both working hours and meeting hours. Work-family conflict was more pronounced in the TT group than in the two other groups. Only 13.2% of individuals did not experience any stress in the past 30 days, and all three groups showed varying degrees of anxiety and depressive tendencies. In addition, all teleworkers experienced adverse physical symptoms before and after the emergency. Conclusion Health issues associated with teleworking should be given adequate attention.

Abstract
STUDY DESIGN Literature Review INTRODUCTION: Computer use in the workplace has increased substantially since the start of the information age in the mid-1980s through 2020. Desktops, laptops, and tablets are essential tools for communication and project management. As a result of the COVID-19 pandemic, many workers have transitioned to work from home (WFH) to sustain public health emergency guidelines, and it is anticipated that many WFH jobs will be maintained post-pandemic. The transition to WFH occurred rapidly without time to establish ideal workstations. Ergonomic assessments that were typically performed in person needed to be performed using virtual technology. PURPOSE OF THE STUDY The purpose of this review is (1) to describe the components of a computer workstation evaluation; (2) to offer suggestions for identifying computer workstation problems that may be contributing to the client's musculoskeletal (MSK) pain and symptoms; (3) to provide suggestions that may improve the safety and comfort at the computer workstation, and (4) to suggest a method of completing the workstation analysis virtually, without onsite in-person evaluation. METHODS AND RESULTS There is a paucity of peer-reviewed literature regarding computer workstation evaluations to be performed in person, let alone using a virtual method. The components of computer workstation evaluations have been recommended by regulatory agencies that survey injuries in the workplace. Prior to 2020, these evaluations were done in person at the office workstation. Modifications in data collection were needed to transition the analysis to a reliable virtual format. The remote method described provides a consistent approach that engages the client in the process.

Abstract
BACKGROUND The number of studies investigating the relationship between office employees and the development of musculoskeletal disorders (MSDs) is limited. Only a few focused on assessing workplace ergonomics of office employees. OBJECTIVE This study aims to investigate the risk of MSDs and associated factors in the office workplaces of a large-size manufacturing company. METHODS Data were gathered from 208 office employees from a manufacturing company via Rapid Office Strain Assessment (ROSA) and Cornell questionnaire. The collected data were analyzed to examine the relationship between ergonomic risk levels and MSDs reported by the office staff. RESULTS The mean ROSA final score is 3.52 (std. dev. = 0.71), chair section is 3.30, monitor and telephone section is 2.18, and mouse and keyboard section is 2.69. Thirty-nine of 208 (18.8%) office workplaces are at risk. The most important factor to raise the risk level is found to be the height and depth of the chair. The Cornell questionnaire results highlight that the highest discomfort severity is related to the neck (32.26%), lower back (23.23%) and upper back (22.26%). The discomforts in the neck (r = 0.362), upper back (r = 0.404) and lower back (r = 0.368) are moderately and positively correlated according to the final ROSA score. The results indicate that the highest risked departments are Accounting, Sub Industry, Production Planning, and Manufacturing Management. CONCLUSION The parameters associated with the chair section should be considered a priority for reducing and eliminating MSDs among office employees.

Abstract
BACKGROUND Computer workstation use is a risk factor for the development of musculoskeletal disorders. Governmental guidelines have been developed as a resource for workstation set-up to minimize this risk. The degree of worksite compliance with guidelines has not been examined. OBJECTIVE The purpose of this study was to examine workstations using the VDT Workstation Checklist to determine compliance, and potential modifications. METHODS Subjects were recruited from a variety of work settings in Erie, PA. Workstations were assessed with the worker present, using the VDT Workstation Checklist. Adjustments and recommendations were made as appropriate. RESULTS Of the 60 workstations examined, 48%did not receive a passing score. All but one were correctable to an acceptable level with minimal low-cost modifications. The recommendation for wrist rests (43%), changes in monitor height (30%) or position (27%) and reposition of the keyboard (13.3%) and mouse (13.3%) were the most frequent modifications. Ten (16.7%) workstations did not require modification. CONCLUSIONS Almost half of workstations reviewed were not in compliance with current guidelines, however almost all (98%) could be brought into compliance with simple modifications. Office workers need guidance in setting up workspace and adjusting ergonomic equipment to provide comfortable and safe work settings and minimize musculoskeletal symptoms.

Occupational Health: Does Compliance with Physical Activity Recommendations Have a Preventive Effect on Musculoskeletal Symptoms in Computer Workers? A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18147604. [PMID: 34300055 PMCID: PMC8307835 DOI: 10.3390/ijerph18147604] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 07/08/2021] [Accepted: 07/14/2021] [Indexed: 11/16/2022]
Abstract
A lack of physical activity in computer workers (CW) can contribute to the development of musculoskeletal symptoms (MSS). Aim: (i) Evaluate MSS over a 12 month and 7 days period, (ii) determine physical activity (PA) levels and compliance with World Health Organization (WHO) PA recommendations, and (iii) assess the relationship between compliance with WHO PA recommendations and MSS. Methods: A cross-sectional observational study comprising 119 computer workers. The Nordic Musculoskeletal Questionnaire (NMQ) was used to evaluate the MSS and the International Physical Activity Questionnaire (IPAQ) was used to analyse the perception of the level of PA. Results: MSS occurred in the lumbar region (56.3%), neck (43.7%), and shoulders (39.5%). 44.7% of the participants reported a low level of PA. The percentage of compliance was similar among women and men (62.2% vs. 58.5%, respectively). Negative correlations were found between pain intensity and metabolic equivalent values. The participants who followed the WHO PA recommendations reported a lower frequency of MSS compared to those who did not, but the differences were not statistically significant. Conclusion: It was possible to conclude that computer workers presented a higher frequency of MSS in the lower back, neck, and shoulders. Regarding the level of PA, participants were mostly classified as low. Participants who followed the WHO PA recommendations reported lower MSS than those who did not. This finding could be important in obtaining successful programs that promote health-oriented physical activity in this group of workers.

Abstract
OBJECTIVE to describe the perception of musculoskeletal pain in the population and how the state of confinement (adopted as a measure to control contagion by COVID-19) has interfered with it, as well as identifying the sociodemographic, occupational, physical, and psychosocial factors involved. METHOD an observational, cross-sectional and analytical study, with simple random probabilistic sampling, aimed at residents in Spain over 18 years old during the confinement period. An ad hoc survey was conducted, consisting in 59 items. RESULTS a total of 3,247 surveys were answered. Persistent musculoskeletal pain or significant episodes thereof increased 22.2% during confinement. The main location was the spine (49.5%). The related factors were decreased physical activity, increased seated position, and use of electronic devices. The psychological impact of confinement was also related to the perception of musculoskeletal pain. CONCLUSION the state of confinement causes an increase in the perception of musculoskeletal pain. The identification of a particularly sensitive population profile, as well as that of the related factors, allows establishing multidisciplinary approaches in health promotion.

Abstract
BACKGROUND As millions of workers have shifted to telework, special accommodations for workers with respect to ergonomics may be required to ensure the workforce remains healthy. METHODS A survey about home office ergonomics and discomfort was sent to faculty, staff, and administrators by email and was completed by 843 individuals. RESULTS Over 40%of the participants reported moderate to severe discomfort (severe low/middle back pain, moderate discomfort in eyes/neck/head, and discomfort in the upper back/shoulders). Laptops (always and often) were widely used (85%) with most using the laptop monitor (55%) of all respondents. Further, less than 45%of the seating conditions were reported as having adjustable arm rests. CONCLUSION As teleworking in makeshift offices becomes more common, the risk of significant discomfort and potentially more serious musculoskeletal disorders may result from poor static postures. Companies may need to accommodate workers by allowing them to take home office chairs, external monitors, keyboards, and mice as laptops are insufficient, ergonomically.

Abstract
BACKGROUND COVID-19 pandemic has necessitated mandatory e-learning in medical and nursing education. How far are developing countries like India (with wide socioeconomic and cultural diversity) geared up for this challenge remains unexplored. At this critical juncture, we aim to evaluate if online teaching methods are as feasible, acceptable, and effective as in-class teaching for medical/nursing students. OBJECTIVES The questionnaire captured: (1) practicability/feasibility of online classes, (2) health issues from online classes, (3) current methods for e-teaching, and (4) student attitudes and preferences. DESIGN Cross-sectional survey. SETTINGS Population-based study in India. PARTICIPANTS Nursing and medical undergraduate students (I-IV year). METHODOLOGY The online questionnaire was distributed to 200 medical and nursing colleges across India. Categorical variables were analyzed using chi-square tests. Binary logistic regression was done to analyze factors predicting health issues in students. p < 0.05 was considered significant. RESULTS Overall, 1541 medical and 684 nursing students completed the survey from 156 cities. The availability of laptop (p < 0.0001), Wi-Fi (p < 0.0001), dedicated room (p < 0.0001), and computer proficiency was more in students of affluent families and those from cities (p < 0.0001). Class duration >4 h/day (p < 0.0001), each class >40 min (p < 0.009) and pre-existing health issues (p < 0.0001) predicted the occurrence headache, eyestrain, anxiety, neck/back pain, and sleep disturbance. Power-point presentation was the most widely (80%) used method of teaching. Only 30% got adequate time to interact with teachers. Only 20.4% felt e-learning can replace conventional teaching. Students preferred: 3-6 classes/day, each class <40 min, 10-20 min break between classes and interactive sessions. CONCLUSION There is a need to improve information and communication infrastructure to enhance feasibility of e-learning for nursing/medical students in India. There should be guidelines (number of classes/day, length of each class, break between classes, curriculum, etc) to improve the retention capacity in students and reduce health issues. Continuous feedback from teachers and students will be required to make e-learning effective.

Abstract
BACKGROUND Several risk factors among packing lines workers can lead to Work-related Musculoskeletal Disorders (WRMSD) occurrence. Foreseeing WRMSD prevention and productivity increase, some furniture manufacturing industries have been investing in the adoption of robotic solutions. In this field, ergonomics plays an important role to verify if automation implementation has been successful. OBJECTIVE This study aims to address the general impact and effectiveness from an ergonomics point of view of the implementation of a robotic aid in a packing workstation. METHODS The Nordic Musculoskeletal Questionnaire (NMQ) was applied to 14 workers of semi-automated packing lines. Some additional questions about occupational conditions were included. In order to assess the ergonomic impact of the robotic aid, Rapid Upper Limb Assessment (RULA) was also applied by trained ergonomists, by analyzing the considered packing workstations before and after the adoption of the robotic aid proposed solution. RESULTS The results showed that trunk torsion was the most highlighted WRMSD risk factor by all workers, associating it with the lumbar pain. The obtained RULA scores demonstrated that the adoption of a robotic aid eliminated this risk factor and, consequently, reduced the corresponding WRMSD risk. CONCLUSIONS The adoption of robotic aids can be instrumental in reducing WRMSD risk in furniture manufacturing industries. Ergonomic studies with workers' participatory approaches seem to be an appropriate strategy to enable the validation and development of industrial robotic solutions.

Abstract
Background The dramatic increase in visual display units (VDU) in the workplace over a 20-year period is linked to the increased prevalence of musculoskeletal disorders (MSDs). Objectives The objective of our study was to compare ergonomic risk factors and work-related psychosocial factors in VDU users with and without MSD. Methods Participants, with and without MSD, working with VDU for more than 4 h a day completed the Nordic Musculoskeletal Questionnaire and the Effort-Reward Imbalance Model and Over-commitment Questionnaire. The workstation of each participant was assessed for ergonomic risk factors using the Rapid Office Strain Assessment (ROSA). Results Sixty-eight VDU users with and 68 without MSDs participated. The workstation ergonomic risk factors as measured with the ROSA were similar for the two groups: 4.5 ± 1.0 for the MSD group and 4.3 ± 0.8 for the reference group (p = 0.10). The work-related psychosocial factors, namely over-commitment, were higher in the MSD group (14.9 ± 3.1) than in the reference group (13.8 ± 3.4; p = 0.041). Conclusions As over-commitment is an indication of intrinsic factors and personal characteristics, the significant difference between the MSD group’s over-commitment score and that of the reference group suggests that interventions to empower individuals are needed. Clinical implications Physiotherapists should only adjust ergonomic workstation risk factors when established as contributory to MSD, and should be cognisant of work-related or individual psychosocial factors that may impact the patient with MSD. The use of ergonomic advice to patients with MSD should be performed with caution, taking all the work place risk factors for MSD into account.

Abstract
The special situation brought about by the coronavirus pandemic and the confinement imposed by the Government, has given rise to numerous changes in working habits. The workers at the universities have had to start a period of teleworking that could give rise to consequences for the musculoskeletal system. The objective of this article is to analyze the impact of the confinement on the musculoskeletal health of the staff of two Spanish universities. A cross-sectional, observational study was carried out on the workers. Data was taken in April-May 2020 and included: The Standardized Kuorinka Modified Nordic Questionnaire, the Perceived Stress Scale and another one on sociodemographic data. This study comprised 472 people. The areas of pain noted during the confinement period concluded that it was less in all cases (p < 0.001). The frequency of physical activity carried out increased significantly during the period of confinement (p < 0.04), especially in women. The type of physical activity done was also seen to modify during this period (p < 0.001), with a preference for strength training and stretching exercises. In conclusion, the confinement gave rise to changes in the lifestyle and in the musculoskeletal pain of the workers at the universities. All of this must be taken into account by health institutions and those responsible for the Prevention of Occupational Risks at Spanish universities.

Abstract
The lockdown, due to the coronavirus, has led to a change in lifestyle and physical activity in Spanish university students. The objective of this study was to analyze the prevalence of musculoskeletal pain and changes in physical activity and self-perceived stress in the student bodies of two Spanish Universities during the lockdown. A cross-sectional study was carried out in a sample of 1198 students (70.6% women). The main instruments used for measuring were the Standardized Kuorinka Modified Nordic Questionnaire and the Perceived stress scale (the questionnaire regarding the practice of physical activity). A reduction in the prevalence of musculoskeletal pain (p < 0.001) was identified in the sample of men and women, an increase (12.5%) in the frequency of carrying out physical activity from moderate to frequent, and the preference for strength training (15.1%), especially among women, was identified. All of this may be taken into account by health institutions when implementing measures to encourage physical activity in both suitable amounts and types, which improves the quality of life of the students.

Abstract
BACKGROUND Cognitive tasks influence gait by reducing balancing abilities. Diverse studies to date have examined dual-tasking and gait. OBJECTIVE This study aimed to determine the influences of smart phone use while walking on lower limb joint angle and dynamic balancing ability. METHODS Thirty healthy subjects were voluntarily recruited from the university population. All subjects were required to perform the tasks under three conditions: not using a smart phone, having a conversation by phone, and playing a smart phone game. Lower limb joint angle and dynamic balance ability related to smart phone use during gait were measured. Motion analysis was used to measure lower limb joint angle changes during gait, while balance measuring equipment was used to measure the dynamic balancing ability. RESULTS In the stability limit test to measure the changes in dynamic balancing abilities, significant differences were found among the different smart phone use conditions. CONCLUSIONS Smart phone use during movements that are required for balance requires special attention, and this study provides important basic data for follow-up studies.

[PMID: 32685744 PMCID: PMC7363260 DOI: 10.5327/z1679443520190329] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Accepted: 09/19/2019] [Indexed: 11/28/2022] Open
Abstract
Background: Musculoskeletal complaints of the arm, neck and/or shoulder not attributed to acute trauma or any systemic disorder (CANS) are characterized by symptoms such as pain, numbness and paresthesia which may reach severe and disabling levels and thus significantly interfere with the performance of work and daily living activities. Computer use at work considerably increased in recent years, being attended with a substantial elevation of the prevalence of CANS among individuals who use computers at work. Objective: To investigate biomechanical and psychosocial risk factors, scapular static imbalance and functional impact on work and daily living activities of upper limb complaints among workers who use computers. Methods: We analyzed ergonomic and psychosocial risk factors by means of MUEQ-Br, scapular static malposition with the SICK-scapula protocol, and functional impairment in work and daily living activities with DASH. The sample comprised 109 employees of a private institution who use computers at work. Results: The average scores on body posture and control over tasks were significantly higher among the symptomatic participants. Scapular malposition did not differ between the symptomatic and asymptomatic participants, but functional impairment did. Conclusion: Awkward posture at work and poor control over tasks seem to contribute to the occurrence of CANS among office workers who use computers. Scapular malposition is not systematically present among individuals with CANS, but the opposite is true. Individuals with CANS exhibited functional impairments.

Abstract
The objective of this study was to reveal RULA method applications in terms of the knowledge, country, year and journal categories. The search was performed using the "Web of Science Core Collection". The period from 1993 to April 2019 was selected. Eight hundred nine results were obtained, of which 226 were used. The largest number of publications was determined to be in the fields of industry and health and social assistance, which coincides with the OWAS and Standardized Nordic Questionnaire methods. By country, the USA stands out for its greater number of research studies and categories that are encompassed. By date, 2016 was the year when more studies were carried out, again coinciding with the Standardized Nordic Questionnaire. By journal, "Work-A Journal of Prevention Assessment and Rehabilitation" is highlighted, as it is for the REBA method as well. It was concluded that RULA can be applied to workers in different fields, usually in combination with other methods, while technological advancement provides benefits for its application.

Abstract
Musculoskeletal disorders (MSDs) are major causes of morbidity among workers. They comprise several signs and symptoms, as e.g. pain, paresthesia, fatigue and limited range of motion, which can be related to work tasks. Workplace-related factors include physical, psychological, social and biomechanical hazards. The main kinetic factors associated with MSDs include repetitive movements, exerting excessive force, awkward postures, compression and mechanical vibration. Accurate knowledge of epidemiological aspects, evaluation of ergonomic hazards and musculoskeletal symptoms, and workplace exercise may help reduce the occurrence of MSDs. The aim of the present review is to analyze the applicability of preventive strategies against MSDs among workers. We performed a narrative review based on a survey of databases PubMed and BIREME and included studies published in English, Spanish or Portuguese. We found that workplace exercise is beneficial for both employers and workers. Risk analysis of MSDs is essential for early identification of occupational hazards and to prevent health consequences and costs associated with absenteeism.

Abstract
Myofascial pain syndrome (MPS) is a type of skeletal pain identified by myofascial trigger points (MTrPs). The formation of MTrPs is linked to muscle damage. The fibroblast growth factor receptor (FGFR1) has been found to cause pain sensitivity while repairing tissue damage. The aim of the current study was to explore the mechanism of FGFR1 in MTrPs. We used a RayBio human phosphorylation array kit to measure p-FGFR1 levels in human control subjects and patients with MTrPs. P-FGFR1 was upregulated in the patients with MTrPs. Then a rat model of MPS was established by a blunt strike on the left gastrocnemius muscles (GM) and eccentric-exercise for 8 weeks with 4 weeks of recovery. After establishing the MPS model, the morphology of the GM changed, and the differently augmented sizes of round fibers (contracture knots) in the transverse section and fusiform shapes in the longitudinal section were clearly seen in the rats with myofascial pain. The expression of p-FGFR1 was upregulated on the peripheral nerves and dorsal root ganglion neurons in the MTrPs group. The spinal Fos protein expression was increased in the MTrPs group. Additionally, the mechanical pain threshold was reduced, and the expression of FGF2, p-FGFR1, PI3K-p110γ, and p-AKT increased in the MTrPs group. PD173074 increased the mechanical pain threshold of the MTrPs group, and inhibited the expression of p-FGFR1, PI3K-p110γ, and p-AKT. Moreover, LY294002 increased the mechanical pain threshold of the MTrPs group. These findings suggest that FGFR1 may regulate myofascial pain in rats through the PI3K/AKT pathway.
