Computer users are at risk of musculoskeletal disorders due to immobility and static activities, therefore the aim of this study was to evaluate the risk factors of musculoskeletal disorders using ROSA method among computer users of administrative section of Sabzevars hospitals.

In this descriptive-analytical study, which conducted 1397, 151 administrative staff were selected from four hospitals by census method. To investigate the pattern of pain in their limbs, participants completed the Body Map checklist and ROSA method was used to assess the ergonomic risk factors at workstations. Data were analyzed using SPSS software and t-test, Chi-Square / Fisher's Exact and Pearson statistical tests was analyzed.

The results showed that the most pain and discomfort reported among the participants were in the lower back (54.32%), back (51.16%), neck (44.24%), and shoulder (38.97%), respectively. Moreover, knee (36.02%). It also showed a significant relationship between age, work experience, exercise and gender with musculoskeletal pain (P-value <0.05). There was a significant relationship between chair score with pain in back, back and knees and mouse and keyboard score with pain in shoulder and wrist (P-value <0.01).

The high prevalence of musculoskeletal pain and the high score obtained in the ROSA method among hospital staff is evidence of the need for ergonomic interventions among them.

Exposure to electromagnetic fields occurs as a result of electronic equipment exploitation. The aim of this study was to evaluate the exposure to electromagnetic fields and its impact on the public health of computer users.
The present cross-sectional study involved 73 male employees. A calibrated gauss meter (model HI-3603, USA) was employed to measure the intensity of electromagnetic fields. A general health questionnaire was also used to assess the health status of the operators. T tests and chisquare test were used for data analysis. Ethical issues were all considered in all stages of the study, and required permission were received.
The electric field intensity range of desktop and laptop displays were measured 0.26 - 1.2 and 0.28 - 0.87 v/m, respectively. The corresponding intensity at a distance of 30 cm from desktop displays was 1.2 v/m; which was more than the standard level. Indeed, general health questionnaire results revealed that 39% of computer users suffer from the lack of public health. The public health status between two groups was significantly different (p Exposure duration factor is not considered in exposure level standards for electromagnetic fields, and a ceiling amount is only reported. According to the results of this study, electromagnetic field intensity values were below standard limits at most of the measured points; however, given the long duration time of equipment usage, the health consequences of this exposure could be accounted as cumulative exposure.

Chronic neck pain is one of the common problems among computer users. The aim of this research was evaluation the effect of therapeutic exercises programs on the rate of chronic neck pain and disability in police staff in Lorestan Province. In this semi experimental study, thirty patients with chronic neck pain with the mean age: 35.73 ± 5.68 years, height: 176.00 ± 5.43 cm and weight: 72.9 ± 10.61 and with at least six months history of neck pain were recruited by personal information questionnaire among computer users of the Police Headquarter of the Lorestan Province. The subjects were divided into two groups with 15 subjects. First group received therapeutic exercises by pamphlet, while the second one was the control group that did not receive any intervention. Neck pain and disability were measured by Neck Pain and Disability Scale at baseline and after 8 weeks intervention period. For analyzing data, first the differences between quantities of pre and post tests were measured, then evaluated by independent t- test (P<0.05). Pearson correlation was also used to consider the relation between variables. The results showed that neck pain and disability in experimental group were significant decreased compared with the control group (p<0.05). But Pearson correlation showed that there was no significant relationship between neck pain, disability and the subjects work experience (p =0. 84, r = -‌0.37). According to the results of this study, it can be concluded that treatment by pamphlet would be useful for treatment of chronic neck pain. Consequently, it seems that applying this method was more helpful for the rehabilitation of patients with chronic neck pain and so it is highly recommended.

The use of computers has become mandatory for doing every kind of work in recent years، and fewer professionals can be found on which to perform the functions without computers. One of the most common complaints of computer users is ocular problems. The aim of this study was to determine the frequency of ocular symptoms in computer users in one of Abadan oil companies. It was a cross-sectional study which was performed on 199 computer users. Simple randomization was used to recruit the sample. The data was collected using demographic sheet and eye fatigue and workplace ergonomics questionnaire and was analyzed by descriptive statistics and Chi-square test using SPSS-PC (v. 19). The sample consisted of 78 females and 121 males. Their age ranged between 30 to 40 years and their use of computers ranged between 21 to 40 hours a week. Frequent eye complaints of the users included، dim display (44. 2 %)، dizziness when looking at the monitor (41. 2 %)، tears and tearing eyes while working with the monitor (38. 7 %)، burning eyes، (38. 2%) and feel eye dryness 38/2% respectively. There was significant relationships between the ocular complaints and age (P-value= 0. 014)، the number of hours of working with computers (P-value= 0. 004)، the position of chair (P-value= 0. 03)، working conditions (P-value= 0. 001) and the position of monitors (P-value= 0. 02). The results of this study revealed the high frequency of ocular symptoms in computer users and the impact of non-ergonomic conditions on the occurrence of these complaints and represented the necessity of modification of ergonomic conditions.

Nowadays computer has changed to an integral component in all the workplaces particularly in administrative ones. Health is directly related to internal social factors of work. This research is conducted to determine the Prevalence of psychosocial complications among computer users and to specify the factors influencing these complications. The method of the present study is correlational and it is conducted randomly on 199 computer users in Abadan Oil Company. The data were collected through demographic questionnaire and psychosocial complications resulting from using computers were assessed. The maintained information was analyzed through Spss-19. The sample compromised 78 females and 121 males aged between 30- 40 averagely, who were using computers 21 to 40 hours on average in one week. The results indicated that 51.8% of participants were suffering from psychosocial Complications due to using computers moderately and 3.1% of them with the minimum frequency faced severe complications. Significant statistical relationships were seen between these complications and working hours, working hours and computer, rest and education. At the present time the existence of psychosocial complications are not damaging in the society which is being investigated; however, the users who use computer moderately are in danger and the way they use computers determines whether in future computer users will be addicted to computers severely or will be healthy users.

The aim of this study was to evaluate the education ergonomic principles on musculoskeletal disorders among computer users at Rasht welfare organization in 2011.

This semi-experimental study، 283 female computer users whom had musculoskeletal disorders randomly assigned into two groups. The case group were educated practically and theoretically about ergonomic issues for three months and ergonomic interventions were carried out for this group. Body map questionnaire was used for estimation of musculoskeletal disorders level and statistical analysis was performed using kolmogorov-smirnov and covariate test.

The results of the present study showed that the highest prevalence rate of musculoskeletal disorders were reported in right knee (27. 91%)، neck region (27. 20%)، lumbar and right shoulder (24. 14%)، left knee (25. 79%)، back (23. 67%). The results of this research showed that there was homogeneity of variance and the meaning of the F covariance at the level of P≤0. 05 revealed that the education of ergonomic principles leads to a reduction of Musculoskeletal Disorders among computer users.

Education of ergonomic principles for the computer users and ergonomic interventions like correction of postures، reducing of work duration، armrest، foot rest، and cushion strengthening exercise and regulating of work station application have a significant effect on the decreasing musculoskeletal disorders prevalence among computer users.

Chronic neck pain is one of the most common problems among computer users. The aim of this research was to evaluate the effects of an eight-week selected therapeutic exercises course and self-treatment with pamphlet programs on the rate of chronic neck pain and disability among computer users. Out of a total number of 196 bank staff members, 66 men with chronic neck pain (mean age: 39.19 ±3.1 years) voluntarily recruited in this study. they were randomly allocated into three groups of selected exercise therapy (N = 18), self treatment with pamphlet (N = 23) and control (N = 25). Chronic neck pain and disability were measured by the Neck Pain and Disability Scale. For analyzing data, pretest-posttest measures were calculated. Then, analysis of variance (ANOVA) and Scheffe post hoc test were used to analyze the obtained data. Pearson's correlation coefficient test was used to determine the relationship between work experience and neck pain and disability rate of subjects. The results of this study revealed 42.85% of the subjects to be suffering from chronic neck pain. There were significant differences between decreased values of neck pain and disability between the three groups (P < 0.01). There was no significant relationships between neck pain, disability and work experience (P =0.086; r = 0.21). Generally, it can be concluded that compared to self- treatment by pamphlet program, the selected therapeutic exercises course under supervision of a trainer was beneficial in reducing chronic neck pain and disability.

Background and aimsScientific and industrial development has led to increased production,which has been associated with different complications, including occupational stress, and increased incidence of work-related musculoskeletal disorders. Musculoskeletal disorders arefrequent causes of absenteeism in developed countries. We designed this study to assess musculoskeletal disorders and occupational stress among video display terminal (VDT) workers in comparison with other office workers.MethodsThis was a cross-sectional study on 72 VDT workers (case) and 145 office workers (control). In this study we used Nordic and Osipow questionnaires in order to evaluate musculoskeletal disorders and job stress, respectively. The questionnaires were filled by direct interview. T test, chi square, Fisher test and logistic regression were used for data analysis.ResultsThe frequency of musculoskeletal disorders among VDT users in the last 12 months was 46.5%, 20.3%, 5.1%, 12.4% and 57.6% in neck, shoulder, elbow, wrist and low back areas, respectively. The frequency of musculoskeletal complaints in neck, shoulder and wrist and mean score of occupational stress was significantly higher in the case group comparing with control group, and both results were statistically significant.ConclusionVDT working is a high-risk job for musculoskeletal disorders. In this study the frequency of musculoskeletal disorders, especially in high-risk regions for this job, was higher in VDTworkers than other office workers. We recommend to perform other studies in order to find non-ergonomic points and postures in these persons.
