Abstract
This study explored the relationship between the design of calf compression sleeves and the comfort of young women in long sitting and standing work environments. By studying the relationship between material elongation and comfort pressure, a prediction model was obtained. The characteristics of the calf models of 94 women were classified, and the influence of different calf characteristics on the pressure distribution and tensile value design was objectively analyzed through simulation tests. The samples were then produced based on the simulation results, and subjective and objective try-on tests and evaluations were carried out. The results show that the difference in the shape of the calf has a certain impact on the pressure distribution and comfort. The predicted value of the theoretical model is in good agreement with the actual test value. The sample can bring a suitable gradient pressure and meet the comfort requirements and safety standards.

Abstract
Objectives: The present study aimed to investigate the effect of corrective exercise intervention (corrective exercise reminding and training software) on musculoskeletal disorders (MSDs), fatigue, posture and working memory among office workers. Methods: A total of 66 office workers participated in the present study. Data collection was carried out using questionnaires (including the Nordic musculoskeletal questionnaire, multidimensional fatigue inventory and Borg rating scale), direct observations of work postures using rapid upper limb assessment (RULA) and rapid office strain assessment, and the n-back test. Results: There was a significant difference between the two groups (intervention and control) in terms of the severity of musculoskeletal discomfort after the intervention. There was a significant decrease in the mean score of trunk posture and the total RULA score in the intervention group after the intervention. The severity of perceived discomfort in all areas except the knee declined during the intervention. There was also a significant difference in physical and mental fatigue scores before and after the intervention. There was a significant difference in the accuracy score of office workers after the intervention compared to before the intervention. Conclusions: Overall, the results confirm the effectiveness of this low-cost, simple and easy-to-use ergonomic intervention.

Abstract
OBJECTIVE Identifying risk factors for suicidal ideation (SI) is necessary for suicide prevention. Associations between self-reported physical activity (PA) and sedentary time and SI in the general population have been found. The current study examines these associations in adults with major depressive disorder (MDD) using objective measures of PA and sedentary time. METHOD Sedentary time and PA were measured with an activPAL inclinometer/accelerometer over 7 days in 52 adults with MDD. Presence and severity of SI was examined with the Mini International Neuropsychiatric Interview. Multinomial logistic regressions examined associations between accelerometer-derived behaviors and SI classification in the full sample and a subsample experiencing a major depressive episode (MDE). RESULTS Sedentary time and PA measures were not significantly associated with SI in the full sample. In those experiencing an MDE, higher light ambulatory PA was associated with lower odds of reporting Low SI compared to None and for Moderate/High SI compared to None. Sedentary time was not significantly associated with SI severity. CONCLUSION Sedentary time and PA were not associated with SI severity, although results could be due to the small sample size. The small effect found for the subsample may suggest that low levels of light ambulatory PA may be a modifiable risk factor for SI during an MDE. We also demonstrated the feasibility of collecting objective data with accelerometers in this population. Future studies are needed to replicate findings to determine whether increasing light ambulatory PA could be useful in suicide prevention during an MDE.HighlightsLight physical activity was associated with lower odds of suicidal ideation.Suicidal ideation was not associated with sedentary or moderate-to-high activity.It is possible to collect objective data for adults with depression.

Effect of a Developed Nursing Stretch Break Application on Work-Related Musculoskeletal Complications and Fatigue among Nurses: An Interventional Study. Pain Res Manag 2022; 2022:7870177. [PMID: 36561913 PMCID: PMC9767720 DOI: 10.1155/2022/7870177] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 09/15/2022] [Accepted: 12/05/2022] [Indexed: 12/15/2022]
Abstract
Objective The present study aimed to develop Nursing Stretch Break (NSB) application to relieve work-related musculoskeletal complications and fatigue among hospital nurses. Methods This interventional study was conducted among 71 nurses (15 men and 56 women with a mean age of 33.32 ± 6.42) employed in Shiraz governmental hospitals, Southwest Iran, for four months. In this study, NSB was developed; it includes eight main menus for the user, including (1) Registration, (2) Stretches, (3) User panel, (4) Questions from the researcher, (5) About us, (6) Contact us, (7) Reports, and (8) Answers to questions. Data were collected pre and post-intervention via the Persian version of the Nordic Musculoskeletal Questionnaire (P-NMQ), the Persian version of the Multidimensional Assessment of Fatigue (P-MAF) Scale, the Persian version of the Numeric Rating Scale (P-NRS), and the Persian version of the Usefulness, Satisfaction, and Ease of use (P-USE) questionnaire. Results NSB application usability testing showed that the mean scores of P-USE subscales were high. The prevalence of work-related musculoskeletal symptoms (WMSs) in the last 7 days in nurses' body parts, except the elbows and knees, was significantly lower after the intervention than before. In addition, the intensity of work-related musculoskeletal pain/discomfort in all body parts, except the knees, was significant relief after the intervention compared to before. The results demonstrated that the difference in the mean score of the total fatigue and its subscales, except "degree of interference with activities of daily living," was significant after the intervention compared to before. Conclusions NSB could be a low-cost and feasible ergonomic solution to improve the nurses' musculoskeletal health.

Abstract
PURPOSE A posture maintained for a long period can be harmful to the health of office workers. This study aimed to estimate the recommended ergonomic duration for maintaining different sitting postures. MATERIALS AND METHODS Forty healthy male and female students participated in this experiment designed to measure perceived discomfort caused by maintaining common static sitting postures of office workers in a simple ergonomic setup for four minutes. The Borg CR10 scale was given to the participants to assess the discomfort in different body parts, before and after each experiment. Based on the mean group discomfort level of 2, the recommended holding time of each posture was estimated. RESULTS The recommended holding time and its discomfort score for each studied posture were tabulated. The shortest holding time of a posture was obtained for the moderate neck flexion (1.61 minutes), and the longest holding time was obtained for legs posture with 90-degree knee flexion (6.45 minutes). CONCLUSIONS The recommended holding time in this study may help to assess the risk of Musculoskeletal Disorders in office workers and train the individuals involved in office tasks in proper sitting behavior.

The Ergonomic Association between Shoulder, Neck/Head Disorders and Sedentary Activity: A Systematic Review. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:5178333. [PMID: 35356625 PMCID: PMC8959976 DOI: 10.1155/2022/5178333] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 01/23/2022] [Accepted: 02/23/2022] [Indexed: 11/30/2022]
Abstract
Background Work-associated upper limb and neck disorders are common occupational disorders throughout the world. These disorders are usually observed more in workers who spend a long time sitting, referred to as sedentary activity (SA). The immediate and distorted risk of sedentary-related problems was considered high in Europe, Australia, and the United States. Even though mediation is convenient, it is likely to reduce office workers' risks of developing cervical and upper body pain due to sedentary work. This systematic review addresses risk factors and evaluates the relationship between SA and upper body disorders in office workers (i.e., shoulder and neck/head). Methods PubMed, Scopus, and Web of Science were searched for articles published between January 2010 and August 2021 in the English language. The three keywords “sedentary,” “upper body elements,” and “work” (and their derivatives) were searched to identify studies and carry out this systematic review. The articles were searched so that all three keywords or at least a derivation of each keyword should appear. Findings. Of the 40 articles that met the enclosure criteria, 32 studies examined the association of SA and upper body elements during both office and computer work. However, three articles were evaluated in the sit-stand work environment, and in the remaining five studies, one was evaluated during teaching, two during hospital work, and two during mixed working conditions. Conclusions Research related to SA focuses mainly on extended risk factors, but there was no focus on other aspects, such as muscle and tendon contractions. As there is a convincing connection between SA and the upper body, our close examination identifies the need to institutionalize a system for collecting, analyzing, and describing the impact and short-term effects of SA on the upper body. Additionally, some suggestions were made to minimize the risk in a sedentary working environment.

Abstract
PURPOSE Work-related musculoskeletal disorders (WMSDs) are common occupational problems affecting the health and productivity of workers worldwide. Ergonomic intervention programs (EIPs) can play an effective role in preventing these disorders in the workplace. Assessing the effectiveness of an EIP is a challenge faced by both industries and researchers. This study was aimed at assessing the effectiveness of an EIP on human resources productivity (HRP), musculoskeletal disorders (MSDs), general health and occupational fatigue in a steel industry. METHODS This study was conducted in a steel industry in Isfahan, Iran, between 2018 and 2021. To assess the effectiveness of the EIP with a participatory approach, training and redesign of workstations, the criteria of HRP, MSDs, general health and occupational fatigue were investigated before and after the intervention, using HRP Questionnaire, Nordic musculoskeletal questionnaire (NMQ), 28-item General Health Questionnaire (28-GHQ), Swedish Occupational Fatigue Inventory (SOFI-20) and Occupational Fatigue/Exhaustion Recovery (OFER-15) Questionnaire, as data collection tools, respectively. RESULTS The implementation of EIP in the studied industry significantly led to an increase in HRP (p < 0.05). The prevalence of MSDs decreased significantly in most regions of the body after the interventions (p < 0.001). In addition, the program significantly improved general health (p < 0.001) and reduced occupational fatigue among employees (p < 0.001). CONCLUSIONS The implementation of EIP was significantly effective in working conditions improvement. Therefore, implementing EIP with participatory approach, workforce training, as well as redesigning of workstations are recommended in industries.

Abstract
OBJECTIVES The active factor along with light exercise can reduce static muscle work and increase muscle flexibility and endurance. Accordingly, this study aimed to design and prototype a new active footrest, implemented in conventional sitting workstations and to test its usability among office workers. METHODS The steps taken to design and prototype the active footrest were a) selection of an exercise appropriate for goals of ergonomic interventions, b) idea development, c) selection of the best conceptual design, d) design with SOLIDWORKS version 2016 software, and e) fabrication of a prototype. Afterward, the usability of the active footrest prototype was assessed among 20 office workers (10 females) using field data by the System Usability Scale. RESULTS Upon the completion of the design steps, the active footrest prototype was prototyped by taking into account design criteria (e.g. functionality, inclusive design, easy application, and reduction of additional body movement), anthropometric data and mechanical properties. The participants rated the usability of the active workstation as 89 ± 8.21 (out of 100) and indicating good usability results. CONCLUSION In this study, an active footrest was designed and prototyped to perform knee extension exercise with the capability of being implemented in conventional sitting workstations.

Abstract
BACKGROUND Municipality cleaners are exposed to food insecurity, Musculoskeletal Symptoms (MSs), and fatigue. OBJECTIVE This study aimed to investigate the effect of food insecurity on MSs, fatigue, and productivity among municipality cleaners. METHODS This study was conducted on 399 Iranian male municipality cleaners with at least one year of working experience. The data were gathered via a demographic/occupational questionnaire, the Persian version of the Household Food Insecurity Access Scale (P-HFIAS), the Persian version of Nordic Musculoskeletal Questionnaire (P-NMQ), the Persian version of the Multidimensional Assessment of Fatigue scale (P-MAF), and the Persian version of Health and Work Questionnaire (P-HWQ). Data were analyzed using descriptive statistics, multiple logistic regression (Forward Wald), and multiple linear regression (Stepwise). RESULTS The findings revealed that 42.6%of the municipality cleaners were in the 'severely food insecure' category. The highest prevalence of MSs in the past week were related to knees (35.8%), lower back (35.1%), and ankles/feet (28.8%). Based on the results, the chance of MSs in the shoulders (OR = 1.66) and ankles/feet (1.60) regions, and MSs at least in one body region (OR = 1.47) was higher in the individuals with severe food insecurity than the others. Considering the P-MAF, food insecurity was associated with the 'degree and severity', 'distress that it causes', and 'timing of fatigue' subscales and 'total fatigue'. Considering the P-HWQ, food insecurity was associated with 'productivity', 'other's assessment', 'concentration/focus', 'supervisor relations', 'non-work satisfaction', and 'impatience/irritability' subscales. CONCLUSION The study revealed an association between food insecurity and MSs in some body regions and fatigue and productivity subscales among the municipality cleaners. Nutritional and ergonomic programs are recommended to reduce municipality cleaners' food insecurity, MSs, and fatigue and enhance their productivity.

Abstract
Background The present study aimed to determine the prevalence of work-related musculoskeletal symptoms (WMSs), identify potential factors associated with WMSs, and determine the association between WMSs and fatigue among nurses. Methods This cross-sectional study was carried out among 500 Iranian nurses. Data was gathered by the 1) Persian version of the Nordic musculoskeletal questionnaire (P-NMQ) to examine WMSs, and 2) Persian version of the Multidimensional Assessment of Fatigue (P-MAF) Scale to evaluate fatigue among the study population. Then, data was analyzed by SPSS version 21 using the χ2 test, multiple logistic regression for detection of potential factors associated with WMSs, and multiple linear regression for detection of potential factors associated with fatigue. Results Ankles/feet, lower back, knees, and shoulders had the highest prevalence of WMSs among nurses within the last 12 months prior to the study. Independent variables including age, job tenure, gender, smoking, shift work, and type of employment were significantly associated with WMSs in different body regions with odds ratios (ORs) ranging from 1.635–2.835. Moreover, WMSs in some body regions were associated with subscales of fatigue and total fatigue. Conclusions Ergonomic and organizational interventions for fitting the job to the nurses considering demographic/occupational characteristics are highly essential to improve musculoskeletal system health and relieve fatigue.

Abstract
This study aimed to assess the effectiveness of short-term workplace-based physical activity education on altering sitting outcomes, maximal oxygen consumption (VO2max) and occupational well-being. Four office clusters (46 participants) of desk-based workers were randomized to either the move in office with education (MOWE) group or the control (CONT) group for 4 weeks. The outcomes were occupational sedentary time, VO2max and workplace well-being. Data were analysed using non-parametric tests. Our study results did not show any significant change in sitting time or VO2max. Nevertheless, workplace well-being of the MOWE group significantly improved when compared to the CONT group, especially in the domains of work satisfaction (odds ratio 11.67; p = 0.001) and employer care (odds ratio 0.167; p = 0.001). Workplace education (MOWE) improves well-being but may not alter sitting outcomes or VO2max in office workers. Workplace education without policy change may not yield positive health outcomes.

Abstract
Objectives. This study aimed to assess cognitive and skill performance at sitting and standing workstations among students from Shiraz University of Medical Sciences. Methods. Forty students (20 females and 20 males) participated in this quasi-experimental study. Tests were performed among randomly selected participants over two consecutive days: day 1, the Beck depression inventory and Beck anxiety inventory were used to assess the severity of depression and anxiety in the study participants, respectively, and Raven's general intelligence test was used to measure intelligence quotient; day 2, five performance assessment tests (cognitive performance assessment tests 'n-back', 'Stroop' and 'advanced reaction time'; skill performance assessment tests 'two-arm coordination' and 'Purdue pegboard') were randomly selected and presented to individuals at each workstation (sitting and standing workstations). At the end of each sitting and standing position, the comfort of the workstation was measured using a visual analog scale. Results. No statistically significant difference was shown between sitting and standing positions in terms of 'n-back', 'Stroop', 'advanced reaction time', 'two-arm coordination' and 'Purdue pegboard'. Participants were more comfortable in sitting positions and more easily distracted in standing positions. Conclusions. Sitting and standing positions had no significant effects on participants' cognitive and skill performance.
