“…Specifically, the sedentary employees experienced high WRMSD in the lower back, upper back, hips/buttocks, and neck due to prolonged posture, with few employees having poor seating posture. It is consistent with other similar studies wherein the lower back and upper back are prevalent among computer workstations [5]- [7], [16]. On the other hand, the standing employees experienced high WRMSD in feet, legs, and knees, which are expected for prolonged standing positions and frequent walking or heavy moving tasks.…”

Work-related musculoskeletal disorders (WRMSD) are disorders of the body experienced by employees affecting muscular, skeletal, and other tissues whose cause has been associated with the work environment. In property management, employees are distributed among its five main service aspectsadministration, security, repair & maintenance, housekeeping, and landscaping. This study assessed the employees' musculoskeletal symptoms through CMDQ & CHDQ and the working posture through RULA & REBA in a property management of a residential complex in Metro Manila. A total of 100 employees participated in the studies, with 67 standing employees and 33 sedentary employees. The CMDQ results showed that WRMSDs are concentrated on the lower limbs (feet, legs, and knees) among standing employees. For sedentary employees, it is prevalent on the lower back, upper back, hips/buttocks, and neck. Since the sedentary employees involve fewer hand movements and lighter loads, the CHDQ results showed that WRMSDs in hand among sedentary employees (mainly from the administration group) is lower than those among the standing employees who often use heavy tools with more hand movements. The posture of the administration group, which makes up most of the sedentary employees, has a medium-risk level with borderline low-risk level. The posture risk of the other four employee groups, mostly standing employees, is medium to high.

Moreover, not using an adjustable chair, height, and keyboards is associated with a higher risk of developing musculoskeletal disorders.…”

Objective: Computer vision syndromes are becoming a major public health concern. Inconsistent findings existed on computer vision syndrome. This systematic review and meta-analysis aimed to estimate the pooled prevalence of computer vision syndrome and identify its determinants. Methods: In this study, the review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Online electronic databases, including PubMed/Medline, CINAHL, and Google Scholar, were used to retrieve studies from 1 December to 9 April 2022. Quality assessment of the studies was performed using the JBI-MAStARI. RevMan and STATA 14 software were used for statistical analysis. Result: A total of 725 studies were retrieved, and 49 studies were included. The pooled prevalence of computer vision syndrome was 66% (95%, Confidence interval: 59, 74). Being female (Odd Ratio = 1.74, 95% Confidence interval [1.2, 2.53]), improper body posturing while using electronic devices (Odd Ratio = 2.65, 95% Confidence interval [1.7, 4.12]), use of electronic devices out of work (Odd Ratio = 1.66, 95% CI [1.15, 2.39]), no habit of taking breaks (Odd Ratio = 2.24, 95% Confidence interval [1.13, 4.44]), long duration of visual display terminal use (Odd Ratio = 2.02, 95% Confidence interval [1.08, 3.77]), short distance screen (Odd Ratio = 4.24, 95% Confidence interval [2.33, 7.71]), and general ergonomic practice (Odd Ratio = 3.87, 95% Confidence interval [2.18, 6.86]) were associated with increased odds of computer vision syndrome. However, good knowledge (Odd Ratio = 4.04, 95% Confidence interval [2.75, 5.94]) of computer vision syndrome was associated with decreased odds of computer vision syndrome. Conclusion: Nearly two in three participants had computer vision syndrome. Being female, improper body posturing, use of electronics devices out of work, no habit of taking a break, long-hour duration of visual display terminal use, short-distance screen, and general ergonomic practice were associated with increased odds of computer vision syndrome.

Background The use of preventive behaviors of musculoskeletal disorders (MSDs) requires proper training, which leads to correct decisions regarding maintaining postures at work and performing stretching exercises. Due to very repetitive work, applying manual force, improper postures, and static contractions of proximal muscles, assembly-line female workers suffer from musculoskeletal pains. It is assumed that structured and theory-based educational intervention using a learning-by-doing (LBD) approach may increase the preventive behaviors against MSDs and reduce the consequences of these disorders. Methods This randomized controlled trial (RCT) will be conducted in three phases: phase 1: validation of the compiled questionnaire, phase 2: determining the social cognitive theory (SCT) constructs that predict the preventive behaviors of MSDs in assembly-line female workers, and phase 3: designing and implementing the educational theory. The educational intervention is based on the LBD approach, and the study population includes assembly-line female workers in electronic industries of Iran, who are randomly divided into two intervention and control groups. The intervention group received the educational intervention in the workplace and the control group does not receive any intervention. The theory-based educational intervention includes evidence-based information along with pictures, fact sheets, and published literature about a good posture at work and the need to perform proper stretching exercises. The educational intervention aims to improve the knowledge, skills, self-efficacy, and intention of assembly-line female workers to adopt preventive behaviors of MSDs. Discussion The present study will evaluate the effects of maintaining a good posture at work and performing stretching exercises on the adherence to preventive behaviors of MSDs among assembly-line female workers. The developed intervention is easily implemented and evaluated in a short period of time based on the improved score of the rapid upper limb assessment (RULA) method and the mean score of adherence to stretching exercises and can be provided by a health, safety, and environment (HSE) expert. Trial registration ClinicalTrials.gov IRCT20220825055792N1. Registered on 23 September 2022 with the IRCTID.
