Abstract
Introduction: Injury to muscles, tendons, ligaments, joints, nerves, blood vessels and soft tissues lead to musculoskeletal disorders. Type of work, the rate of repetition, severity and duration of work are risk factors for musculoskeletal disorders. Food plants contain repetitive motions so it is necessary to study the prevalence of musculoskeletal disorders in this study.
Methods: This study is a descriptive- analytical study to investigate the prevalence of musculoskeletal disorders in the one of the food manufacturing plans. Therefore, 200 workers in this industry were examined. In order to determine the prevalence of musculoskeletal disorders and symptoms Nordic questionnaire was used and to identify different body parts affected, body map questionnaire was used. Data was analyzed using SPSS (Ver. 18).
Results: The most common symptoms of patients were related to low back. Chi square test showed a significant relationship between sex and prevalence of symptoms in the areas of back, shoulder and
elbow of workers during the past 12 months (P <0.05). But in the neck, thighs, knees and feet we did not
see any significant difference.
Conclusion: Sex is a risk factor for development musculoskeletal disorders, so as the prevalence of symptoms in women was more than men.

Abstract
Background: Work-related musculoskeletal disorders are the most common occupational diseases. Between industries, pottery, with several thousand years of activity, still retains its nature as a manual job. This has led to increased risk of musculoskeletal disorders among potters. The aim of this study was to assess the prevalence of musculoskeletal disorders and related risk factors by OCRA method in Meybod potters in 2009.
Methods: This was a cross-sectional analytical study. Target population consisted of, all potters working in the pottery workshops in Meybod. There were 17 workshops with 54 potters. Information about the prevalence of musculoskeletal disorders was collected using Nordic questionnaire. The OCRA method was used to assess risk factors for musculoskeletal disorders of upper limbs.
Results: The results of Nordic questionnaire showed that approximately 59.3% of the potters had at least one upper extremity musculoskeletal disorders in the last year. Wheel workers had the highest prevalence (34.4%). Independent T-test showed no significant difference between the final score of OCRA index between potters with and without upper extremity musculoskeletal disorders (P=0.047).
Conclusion: The results of this study showed that the risk of musculoskeletal disorders of upper extremities is high among potters. So it suggested that possible corrective actions take place as soon as possible and periodic evaluations are also necessary for early detection of these disorders.

Abstract
Background: One of the most main jobs in the automotive industries is assembly that its activities include hand motions, navigation of pieces and using controlled forces for joining of them together. Awkward posture is one of the most important risk factors in incidence of musculoskeletal disorders. There are different methods to assess those factors. This study was conducted to illustrate the correlation between the results of MFA method and RULA in the assessment of musculoskeletal disorders risk.
Methods: In this cross-sectional study 37 jobs were selected as a sample by using of Cochran formula. In this study, 80 postures were assessed by using of two mentioned methods to determine the musculoskeletal risk level.
Results: The results of MFA method indicated that 17.5%, 11.3% and 7.5% of jobs in shoulders, low back, wrist and fingers were sequentially in “very high” level of modified actions preference. On the other hand, the results of RULA assessment pointed out that 46.3% of jobs were in level 3 of modified actions and 38.8 of them were in level 3 of those actions. Analyzing of data by using of Spearman test displayed that there is significant relationship between RULA scores of shoulders, body and neck with the level of modified action in MFA method (P-value≤0.05) and sequentially, the correlation coefficients were 0.782, 0.787 and 0.8.
Conclusion: In general view, there are many similarities between two methods in both the way of study and the final assessment however, one of the main differences of them is that the results of MFA method are more reliable when all parts of body involve in physical activities. In addition, in MFA method, the details of body’s limbs are assessed more than RULA method.

Abstract
Introduction: Appropriate office workstation design and adjusted keyboard slope could prevent upper extremity musculoskeletal disorders caused by CTDs. The purpose of this study was to compare wrist and finger motion angles during typing in different workstations with different keyboard slopes.
Methods: In this experimental study, 10 female typists of university workers were chosen randomly. Test was performed on two different adjustable and non-adjustable chairs with four different keyboard slopes including 15, 7, 0, -7 degrees. Wrist and fingers kinematic data were calculated by Vicon motion analysis system and MATLAB software.
Results: Average wrist flexion angles were significantly different in different keyboard slopes. In adjustable workstation, the lowest mean value of maximum, average, min mum of flexion was measured for keyboard whose slope was adjusted to 15 degrees. The lowest mean for observed flexion in the metacarpophalangeal joints in the second and fifth fingers was measured in workstation with adjustable seats and keyboard whose slope was adjusted to 15 degrees. In the proximal interphalangeal joint of the second finger, the lowest mean was obtained in the workplace with adjustable seats and the keyboard whose slope was adjusted to 15 degrees.
Conclusion: During typing on keyboard, as much as the finger joint angles are close to zero degree, less stress is put on the joints. In this study, the lowest means for the degrees of joint flexion were observed in the workstations with adjustable seats and the keyboard with 15-degree slope.

The aim of this research was to determine the prevalence of musculoskeletal disorders in various organs of the carver, assessing the carotid posture and workstations, determine the individual and ergonomic risk factors the occurrence of musculoskeletal disorders
Method:
The present study is done through descriptive cross-section method to assess the organic risk work-related musculoskeletal disorders that loom over 152 handloom weavers. Our data collection tools were: demographic questionnaire, job Nordic questionnaire, and body map prevalence of musculoskeletal disorders to decide the rate of symptoms. Then, we took film from handloom weavers while wearing to know the condition of their bodies. After reviewing the films, we assigned posture marks to each duty using ocra software at the end, data were analyzed and T-test using spss-20.
Result:
The result Ocra showed that the most frequent incidence of pain in different organs of the body during last year was neck and shoulder the average Ocra is 3.65.This indicate that most of the handloom weavers are at high risk and are in the red zone. According to the statistics 1.3% of these weavers are in slight risk and 32.2% are at low risk and 64.4% are at high risk. Thus, our study showed that the level of exposure to the risk in level 4 is more than the other levels. Hence, the station needs immediate correction.
The results also showed that there is a significant relationship between the risk level of Ocra and the prevalence of musculoskeletal disorders (pain, discomfort, etc., during the past 12 months) in the neck, shoulder and wrist.
Conclusion:
Based on Ocra indices results, handloom weavers are at high risk of musculoskeletal injuries that indicates the inappropriate (unsuitable) work condition and environment that should be corrected as soon as possible.
On the other hand, the Ocra method of evaluation is an appropriate tool to confirm the level of risk factors in the muscoskeletal disorders of handloom weavers.
