Work-related musculoskeletal disorders are one of the most common occupational complaints among dentists. Accurate assessment of the pain caused by these disorders is of paramount importance in its better control. Therefore, this study aims to investigate the prevalence of musculoskeletal disorders and evaluate the correlation of the Visual Analogue Scale with the different dimensions of the McGill Pain Questionnaire in dental students in the city of Tehran.

In this cross-sectional descriptive-correlation study conducted among 120 dental students in Tehran in 2020-2021, data related to musculoskeletal disorders were collected through the Nordic questionnaire. Pain assessment was also performed using the Visual Analogue Scale and McGill Pain Questionnaire. The data were analyzed using SPSS version 26 and statistical tests, including chi-square, Spearman, and Pearson correlation, to examine the relationship between the two measures.

In this study, the highest prevalence of disorders was observed in the neck region (42.5%), upper back (35%), and lower back (31.7%). Neck pain and discomfort, in the last 12 months, caused a reduction in work activity more than any other region among the participants. Significant correlations were found between the Visual Pain Scale and the Sensory (r=0.543, p=0.011), Affective (r=0.549, p=0.020), and Evaluative (r=0.538, p=0.035) dimensions of the McGill Pain Questionnaire.

The present study indicates that work-related musculoskeletal disorders are common in dental students. There is a high correlation between the Visual Pain Scale and the McGill Pain Questionnaire in assessing pain intensity.

 Musculoskeletal disorders are among the main causes of discomfort and disability in dental laboratory workers and are increasing due to the type of occupational tasks of the employees. This study aimed to investigate the prevalence of musculoskeletal disorders in the staff of dental laboratories in Yazd. 

 This descriptive cross-sectional study was performed on 37 dental technicians. The Nordic questionnaire was used to collect data on musculoskeletal discomfort. The data was analyzed by SPSS (Ver. 20) using descriptive statistics.

 The highest frequency of discomfort in the last 12 months was in the lumbar region (43.2%), neck (29.7%), and wrists and hands (21.6%). The highest frequency of musculoskeletal disorders in the last 12 months was in the lumbar region (24.3%), neck (16.2%), back, buttocks and thighs (10.8%). Musculoskeletal disorders in the lumbar (21.6%) and shoulder region (24.3%) were the most common causes of absence from work and job change, respectively.

 The results of this study showed a high frequency of musculoskeletal disorders in dental laboratory workers, and a high frequency of job change and absence from the workplace due to these disorders.

 Office workers, regardless of educational principles, may be exposed to musculoskeletal injuries due to the nature of their work. Therefore, the present study was conducted to investigate the effect of ergonomics training in reducing musculoskeletal disorders among the administrative staff of an Ilam University of Medical Sciences campus.

 In this descriptive-analytical study, 178 administrative staff of Ilam University of Medical Sciences Campus 1 was examined. Musculoskeletal disorders were evaluated using the Nordic questionnaire. Ergonomic risk factors of the workplace were assessed by Rapid Administrative Strain Assessment (ROSA) before and after the training. Data analysis was done through SPSS version 26 statistical software.

 According to the findings obtained from the Nordic questionnaire, it was found that the most disorders in the past year were in the back (56.2%) and neck (55.6%) areas and the ROSA evaluation results showed that 24.4% of the subjects the study was at the ergonomic level with high risk. After the implementation of training programs, the results showed that the prevalence of disorders in 9 areas decreased. Also, demographic variables did not have a significant effect on the prevalence of musculoskeletal disorders. (Significance level 0/05 is assumed)

 The results of this study showed that ergonomic training can be an effective method to reduce musculoskeletal discomfort in office work environments.

In recent years, the rapid growth of technology and the use of computers have affected almost all workstations, and musculoskeletal disorders are very common among computer users. Therefore, this study aimed to evaluate the ergonomic status and prevalence of musculoskeletal disorders in computer users.

This descriptive-analytical study was conducted on 100 Bank staff in Bojnurd, Iran. The Rapid Office Strain Assessment (ROSA) method and Nordic standard questionnaire were used to evaluate the ergonomic status, and determine the prevalence of musculoskeletal disorders, respectively. The data were analyzed in SPSS software (version22), through the Chi-square test, one-way ANOVA, and descriptive statistics.

The mean±SD age and work experience of users were determined at 34±6.9 and 15.1±0.7 years, respectively. A significant relationship was observed between gender and pain in the back (P=0.037), wrist/hand (P=0.032), knee (P=0.024), and upper back (P=0.054).The most common skeletal-muscular disorders in people were observed in the waist, neck, and upper back areas in the body, respectively. The mean±SD final ROSA score of the chair, phone-monitor, and mouse-keyboard was estimated at 3.7±1, 3.6±1.1, and 3.65±1.2, respectively, and the mean±SD of the final ROSA score was 4.4±0.9. Based on the ROSA method, 35 workstations had a risk score≥5, indicating the need for further evaluation and immediate corrections.

According to the results of this study, it was found that work-environment factors that affect skeletal-muscular disorders include chair, mouse-keyboard, and phone-monitor, in the order of significance. Therefore, most of these injuries can be prevented by correcting the ergonomics of chairs and the proper placement of the mouse-keyboard.

Working with a computer and workplace conditions expose people to risk factors of musculoskeletal disorders (MSDs). This study aimed to assess posture, examine MSDs, and determine, weigh and prioritize the risk factors among computer users by a neural network algorithm. 

This descriptive-analytical cross-sectional study was conducted in six phases on computer users in 2019. The status of MSDs was determined via Nordic musculoskeletal questionnaire (NMQ). The factors affecting these disorders were determined by the ROSA method, and then these factors were weighed by the neural network algorithm. The data were analyzed in IBM SPSS Modeler.

The mean age and work experience of the users were 34 ± 6.9 and 1.5 ± 0.7 years, respectively. Most of years were observed at the lower back, neck, and upper back, respectively. The final mean scores of the chair, telephone-monitor, and mouse-keyboard were 3.7 ± 1, 3.6 ± 1.1, and 3.65 ± 1.2, respectively and the final mean score of ROSA was 4.4 ± 0.9. The greatest correlation with the ROSA score was observed in chair (R2 = 0.46), followed by telephone-monitor (R2 = 0.43), and mouse-keyboard (R2 = 0.42). The highest predictor importance of the effective factors based on the neural network algorithm prioritization belonged to the chair (48%), followed by telephone-monitor (28%) and mouse-keyboard (24%). The accuracy of the neural network algorithm in examining the effect of factors on musculoskeletal disorders was 98% based on the ROSA score.

Factors affecting years due to working with computers are the chair, telephone-monitor, and mouse-keyboard, respectively, as prioritized by the neural network algorithm. These disorders can be prevented by ergonomic modification of users’ chairs and correct placement of the monitor and telephone.

According to epidemiological studies in the healthcare field, the prevalence of musculoskeletal disorders is increasing among dentists. Since the prevention of such disorders is crucial, the present study was conducted to determine the prevalence of musculoskeletal disorders and various physical interactions and related factors among dentists in Bojnourd.

The present study is descriptive cross-sectional. A total of 28 dentists in Bojnourd were selected by purposive sampling. The Nordic questionnaire was completed through an interview. Data were analyzed by SPSS software (V 22) using descriptive tests, Chi-square, and T-test.

The mean age and work experience of the subjects were 38.32±6.32 and 12.57±8.02 years, respectively. A study on 18 men and 14 women indicated the highest percentage of pain or discomfort in the back (75%), neck (71.4%), shoulders (60.7%), and waist (50%). The prevalence of neck and shoulder pain was higher in women (P=0.008). The Chi-square test showed that these disorders intensify with increasing age and work experience. Also, the t-test showed that individuals with BMI higher or lower than normal are more prone to musculoskeletal disorders.

A high prevalence of musculoskeletal disorders was observed in the neck and upper extremity. Regarding this issue, interventional ergonomics and preventive physiotherapy exercises in the workplace, training, and informing dentists about the injuries seems necessary.

safety occupational safety researchers have always analyzed climate analysis. Climate can be investigated at different organizational levels. The purpose of the present study was to examine the safety climate among Nain tile factory workers and its relationship with having a history of occupational accidents.

Musculoskeletal disorders are one of the most important problems in the nursing profession. Considering the importance of the subject and the dangers of this disorder, the purpose of this study was to investigate the prevalence of musculoskeletal disorders and the factors affecting it in the nursing profession.

The present study is a cross-sectional-analytical study in which the risk factors and prevalence of musculoskeletal disorders in the nursing profession of Khorramabad teaching hospitals in 1398 have been evaluated. A total of 210 nurses were enrolled in the study by stratified sampling. The data collection tool was the Nordic Musculoskeletal Disorders Questionnaire. Mann-Whitney and Chi-square tests were used to analyze the data.

In this study, out of 210 samples, 114 (54.3%) were male and 96 (45.7%) were female. The mean age of nurses was 30.46 ± 7.93 years with a maximum of 55 years and a minimum of 20 years. The mean BMI of nurses was 24.40± 2.3 with a maximum of 34.05 and a minimum of 17.54. The overall prevalence of musculoskeletal disorders in at least one member was 206 (98.1%).  There was a significant relationship between gender and musculoskeletal disorders in the neck, shoulders and wrists (p<0.05). But there was no significant relationship between gender and musculoskeletal disorders in the elbow, upper back, lower back, buttocks, buttocks, thighs, knees, ankles (p> 0.05). Also, a significant relationship was observed between BMI and musculoskeletal disorders in the elbow and upper back (p<0.05).

The most musculoskeletal disorders of the nursing staff were in the shoulders, neck, knees, upper back and lower back, ankles, thighs, buttocks, buttocks, wrists, and elbows, respectively. Therefore, regarding the reduction of musculoskeletal disorders in nurses, nursing managers should be aware of the results of this study, by establishing proper communication with nurses and their support and creating a suitable environment for nurses to continue their professional activities in order to reduce physical needs and psychological pressures. And focus on increasing the quality of life.

Nowadays one of the most important occupational health issues is musculoskeletal disorders, which are prevalent in almost occupations. The purpose of the study is to evaluate musculoskeletal disorders and related factors in the housewives of Yazd province.

This cross-sectional study was carried out on 396 samples selected housewives in Yazd province in the year 1398. The information was collected by completing the Nordic questionnaire through the selected samples. The prevalence of musculoskeletal disorders and ergonomic assessment of posture was assessed by using the questionnaire and the REBA method, respectively. Data analysis was done by using the independence and ANOVA tests in SPSS version 22.

The most prevalent musculoskeletal disorders in the housewives were in the lumbar, knee, and neck that 67%, 53%, and 43% of the samples had the disorders, respectively. The prevalence of musculoskeletal disorders in some areas of the body increased because of an increase in the number of children, declining in welfare, and the use of assistive devices at home. Also, the prevalence of musculoskeletal disorders has had a significant impact on the calf and ankle.

The results showed that the prevalence of musculoskeletal disorders in the study population is high. Age, marriage age, height, weight, number of pregnancies and children, education, status of welfare and residential, daily exercises, used equipment, elevator, and staircase were the things that produce musculoskeletal disorders. According to the big population of housewives, it is recommended more extensive studies on disorders in this group.

Annually, a percentage of the profits from the sale of goods and services by producers are spent on costs of musculoskeletal disorders due to non-compliance with ergonomic conditions. These costs are not favorable for organizations and employees and in most cases, ergonomic risk factors affect the quality of life of employees.

The present field study was conducted as a census on 193 workers with medical records in one of the domestic automotive industries on December 2018. The highest prevalence of musculoskeletal disorders belonged to 16 workers, so their workstations were analyzed. Questionnaire with the help of Nordic questionnaire and through interviews with workers has been one of the methods of collecting data. Each of the selected workstations was analyzed with OWAS method after job photography and video recording.

The results showed that three work stations from the viewpoint of Action Categories are at the level of three, three work stations at the level of two and one station at the level of one, and then the costs of incidence and treatment and related actions due to establishing ergonomic conditions were calculated.

Cost of workstations analysis, Preventive actions and also designing a process to reduce the musculoskeletal abnormalities of the staff, which results in ergonomic conditions, compared with the cost of incidence and treatment of musculoskeletal complications is cost-effective for this automotive industry.

Faculty Members of the university have a fundamental role in education and its quality. Working conditions of the faculty members have made them face severe musculoskeletal disorders. The spread of the COVID-19 virus, the closure of universities and the virtual education have made working conditions of the faculty members more difficult than before. This study was conducted to investigate the effect of the virus on the prevalence of musculoskeletal disorders of the faculty members of the university and the extraction of variables affecting the disorders.

This descriptive-survey study was conducted in 2020 on 220 faculty members of Yazd University who were selected by the simple random sampling method. Data were collected using the standardized Nordic questionnaire in two stages before and after the spread of the virus and were analyzed in SPSS 25 by paired sample t-test, independent t-test, and analysis of variance.

Musculoskeletal disorders after the spread of the virus in most organs have increased significantly, so that frequency percentage in the neck for the three campuses has increased from 36%, 40%, and 31% to 55%, 52%, and 44 %. There is a significant relationship between gender, work experience, and teaching method with the prevalence of disorders. Most disorders were in the back, neck, and knees.

A small percentage of faculty members perform sports activities and daily exercises that by planning on them can reduce the disorders. The university can also prevent the centralization of education at a specific time by dividing the virtual education during the day and week and reduce the disorders.

Incidence of musculoskeletal disorders is one of the effects of inappropriateness between subjects and technology, which reduces the level of human immunity, occurrence of occupational disabilities, loss of working time and increasing costs. The aim of this study was to evaluate risk factors of musculoskeletal disorders for assemblers in an electric industry workerand effect of interventions on reducing the level of these disorders.

This interventional study was carried out among 75 women workers in a wall plug factory having more than one year working experience in 2017. The data collected were analyzed by using SPSS software version 20 and Chi-square, regression, independent t-test, after reviewing medical documentation and completing QEC and Nordic questionnaires before and after ergonomic interventions which was done in the form of training and corrective actions.

According to the results, the highest reported musculoskeletal disorders were in the shoulder, wrist, lower waist, upper lobe with frequency of 68%, 61%, 58% and 51%, respectively, that with respect   to ergonomic interventions, this reduction for each area was 60%, 46%, 49% and 46%, respectively, which was relatively a good reduction in abnormalities.

The interventions in this industry have shown the effectiveness of these methods for reducing musculoskeletal disorders, and it can be concluded that educational interventions and making activities periodically together have been effective in reducing disorders.

Low mobility and muscle weakness are increasing musculoskeletal disorders (MSD) in many individuals. Therefore, the present study aimed to investigate the effect of 8-week resistance exercises on reducing the prevalence of the symptoms of MSD in the neck, shoulders, wrists, and back among the teachers of Bardaskan, Iran.

Firstly, a total of 384 subjects were randomly selected from the school teachers of Bardaskan, and demographic and Nordic questionnaires were completed for all of them. Then, the prevalence of the aforementioned symptoms in each of the studied organs was evaluated. Accordingly, 80 eligible individuals were identified for this study according to the inclusion criteria and allocated to two intervention (n=40) and control (n=40) groups. In addition, forms of A (i.e., intervention) and B (i.e., control) were used for the random assignment of the groups. The Nordic questionnaire was completed for both groups 24 h before the intervention. After the termination of the 2-month intervention period and 24 h after the last exercise session, the Nordic questionnaire was again completed for both groups. For the result comparison, the GEE statistycal test was used.  

The results of the examined hypotheses showed that that resistance exercises had no significant effects on reducing the prevalence of the symptoms of MSD in the neck, shoulders, wrists, hands, buttocks, and back of school teachers, compared to that reported for the last year and 2 months (P>0.05); however, these exercises significantly decreased the severity of the pain in the intervention group over the last 7 days (P<0.05).

Due to the low impact of resistance training, it is recommended to carry out further studies on redesigning the exercise plan, changing the type and the duration of exercises, or increasing the sample size in order to relieve the pain in the studied regions.

In recent years, the rapid growth of technology and the use of computers have affected almost all office work stations. Musculoskeletal disorders are very common among administrative staff. Therefore, this study aimed to evaluate the ergonomic status and prevalence of musculoskeletal disorders in office staff affiliated to Shahid Beheshti University of Medical Sciences.

This study was conducted on 96 office staff affiliated to Shahid Beheshti University of Medical Sciences in 2018. To evaluate the ergonomic status, ROSA method and to determine the prevalence of musculoskeletal disorders, Nordic standard questionnaire was used. The data were analyzed using Chi-square, one-way ANOVA and descriptive statistics with SPSS-22 software

The prevalence of musculoskeletal disorders in staff was higher in the neck (62.5%), shoulder (57.3%) and lower back (57.3%) than the other organs. The average ROSA score in the society was 4.9 ±1.02. 70.8% of the subjects were evaluated in warning zone and 29.2% in the area of immediate corrective measures. There was a relationship between the final score of ROSA and the prevalence of musculoskeletal disorders in the neck, shoulders and lower back. There was also a relationship between age, gender, work experience and the final score of ROSA.

The ROSA method was determined as a suitable tool for evaluating the ergonomic status of office stations. According to the results, employees are at risk of musculoskeletal disorders and have workstations with ergonomic risk factors. Therefore, tensile movements, adjusting work schedules, using equipment such as a document holder and Headset are recommended.

Musculoskeletal disorders are one of the most important and most common occupational injuries that lead to disability and absence from work. Given the increasing prevalence of musculoskeletal disorders, this study aimed to investigate the prevalence of disorders in gynecologists in 2017.

In this cross-sectional study, all experts participating in the 14th International Congress of Gynecologists and Obstetrics of Iran were selected based on a census method. Finally, 50 subjects participated in the study. Nordic questionnaire including demographic information and general and specific occupational questions were used for data collection. Data were analyzed using two-sample t-test, chi-square test.

The highest and lowest level of pain perception among specialists after the onset of work was on average in the neck area (81%) and elbow (15%). The frequency of pain and discomfort experienced by musculoskeletal disorders during the last year was Neck (73%), Lower Back (63%), Shoulders (41%), Upper Back (36%), Knees (34%), Wrists (24%), Arms (16%) and elbows (7%) reported. Also, there was a statistically significant relationship between age, work experience, hours of activity per week with pain in different areas of the body (P-value <0.05).

The prevalence of skeletal disorders in gynecologists is high because the main tasks of this occupation are to bend for examination. Ergonomic assessment with more accurate methods as well as ergonomic interventions in the workplace of gynecologists with lower job satisfaction is needed.

Musculoskeletal disorders (MSDs) are among the major causes of occupational injuries and disability in industrialized and developing countries. The aim of this study was to compare MSDs in female staff working in radiology department of Imam Khomeini and Bouali Sina hospitals in Sari, Iran, 2018.

The research population, in this cross-sectional study, included 45 female staff working in radiology departments who were selected via census sampling. Then, 20 subjects who met the study inclusion criteria were studied. The Nordic Musculoskeletal Questionnaire (NMQ) was administered to collect the data. Statistical analysis was performed in SPSS V16.

The mean age of participants was 37.7 years. Findings showed that during the past 12 months, musculoskeletal disorders were more prevalent in shoulder area (65%), wrists and hands (64.7%), and elbows (55%). There was no significant correlation between acute skeletal disorders and age, height, weight, and BMI.

The prevalence of musculoskeletal disorders has an increasing rate in radiography staff. Lack of appropriate trainings result in more occupational disabilities, therefore, improving working conditions and use of electronic systems rather than mechanical systems for radiation chamber door are suggested.

Work-related musculoskeletal disorders are the most important cause of lost workdays and inefficiencies, medical costs, and workforce injuries. The aim of this study was to investigate the musculoskeletal disorders in employees of Babol health centers in 2017.

This cross-sectional descriptive-analytic study was conducted on 210 employees of Babol health centers. A questionnaire including demographic information and the Standard Nordic Questionnaire were used for data collection. Data were analyzed using descriptive statistics and chi-square test in SPSS 22 software.

The mean age of the personnel was 40.07 ± 8.46. The highest prevalence of disorders was reported in the waist (58.9%) and neck (54.1%) in the last year, and the lower back (46.9%) and neck (44.9%) in the last seven days. In the last year, 25.7% and 15.5% of the staff required the use of medical and physiotherapy services, respectively, due to disorders. There was a significant relation between behind-the-desk hours with neck (P= 0.002) and knee pain (P= 0.049).

In order to prevent and control musculoskeletal disorders, regarding the high prevalence of them, it is necessary to program for educational workshops to increase personnel knowledge, as well as ergonomic interventions, redesigning the workplace, and using appropriate anthropometric equipment.
