    Aims: Manual tasks and load carrying and handling are the most important tasks in a sofa making workshop. Evaluation of these types of tasks is very important for identifying the health risks to which workers are exposed. The aim of this study was the ergonomic evaluation of occupational tasks in a sofa making workshop based on KIM and presentation of corrective actions.
    Instruments and
    Methods
    The present descriptive cross-sectional study was conducted in a sofa making workshop in Ardabil in 2017. All tasks of the sofa making workers (n=22) were examined, among which 7 main tasks were identified. The identified tasks were analyzed, using KLM-MHO and KLM-LHC methods. Manual tasks and load lifting and carrying tasks were evaluated, scored, and checked out, using EXCELL 2010.
    Findings: Among the tasks examined, the tasks of woodcarving, preparation for coloring, and sofa dressing showed the highest final score (Risk Grade 4), followed by jointing wood parts with glue and coloring (Risk Grade 3). Most items with high workload were related to grips status, repetitive movement in the hand-finger area, position and repetitive movements of the joints at the end of motion range, and curved forward trunk posture.
    Conclusion
    In carving, preparation for coloring, and dressing tasks, the amount of workload is high. In jointing wood parts with glue and coloring tasks, the amount of workload increases dramatically. And, in designing layout on wood and cutting tasks, the amount of load increases.

    Aims: Most of the occupational tasks, in addition to physical work, have a part in mental and cognitive processing. The aim of this study was to evaluate the relationship between mental workload and musculoskeletal disorders in nurses working at day and night shifts in the state hospitals.
    Instruments and
    Methods
    The present descriptive-analytical study was conducted among 152 nurses, working at day and night shifts in state hospitals in Neishabur in 2017. These samples were selected by simple random sampling method. The Nordic Demographic Questionnaire and the NASA-TLX Standard Questionnaire were used to measure the prevalence of musculoskeletal disorders and mental load. The data were analyzed by SPSS 20 software, using descriptive statistics and Pearson correlation coefficient, Chi-square, and independent t-test.
    Findings: There was an increase in the mean score of mental labor and musculoskeletal discomfort, especially in the waist and knee area. A significant relationship was found between the variables of labor with musculoskeletal discomfort (p
    Conclusion
    Mental workload and musculoskeletal disorders in neck, elbow, upper back, waist, and knee in shift work is higher than day care workers. Also, there is a relationship between musculoskeletal disorders and workload.

    Aims: Knee osteoarthritis is the most common joint disease. It has more prevalence and severity in women than in men. The aim of this research was to compare the navicular drop (ND) and hallux deviation (HD) in women with different knee osteoarthritis (OA) based on the radiographic grades of 1 to 4.
    Instruments and
    Methods
    The present research was a descriptive cross-sectional and causal-comparative study. The study population included women with knee osteoarthritis in Tehran. The statistical sample included 87 female patients with knee osteoarthritis, who were selected based on the simple purposive and non-probability sampling method from patients referring to specialized clinics and Akhtar Hospital in 2015. The number of knees with knee OA was 168, which were divided into 4 groups based on the Kellgren-Lawrence grading scale. One-way analysis of variance was used to compare the difference between the groups in terms of the amount of navicular drop and the hallux deviation, and for significant results, Tukey's post hoc test was applied.
    Findings: There was a significant difference between the first and second groups regarding the extent of ND, which was mostly observed in Group 2. It was non-significantly higher in Group 4 in comparison with Group 3 and higher in Group 3 than in Group 1. The mean of HD increased from Group 1 to 4 but not significantly.
    Conclusion
    Higher drop in navicular is a risk factor for the development of knee osteoarthritis radiographic grades.

    Aims: Musculoskeletal disorders are the most common work-related complications in industrial environments. Inappropriate body working postures are considered as one of the most important risk factors for musculoskeletal disorders. The aim of this study was the ergonomic assessment of body working postures among the employees of a car services workshop, using OWAS technique.
    Instruments and
    Methods
    This study was a descriptive cross sectional study conducted in 2017 in a car services workshop selected through simple random sampling method. The study sample was one of the representatives of Iran Khodro Company in Ahwaz. Based on the study sample, 960 different body postures were recorded. Using OWAS method as a posture assessment method, each of the occupations was photographed for 40 minutes at 30 second intervals. The data were evaluated by Excel 2012 software and the photographs were evaluated by OWAS method.
    Findings: Worker's work environment was ergonomically appropriate. Generally, 95.0% of the working postures were related to Level 1, indicating that most of the workstations did not need to be modified. The repetitive movements had the highest body working postures score.
    Conclusion
    Just in the case of car repairers, there was a need for redesigning the workstation. In other cases, the tasks of repairing, coloring, and pressing were related to Code 1.

    Aims: Work-Related Musculoskeletal Disorder (WMSDs) is a major health problem among many professionals in the developing countries. The aim of the present study was to assess the effectiveness of comprehensive body mechanics on pain and disability among nurses with low back pain.
    Materials and Methods
    In this study, quantitative, pre-experimental one group pre-test post-test design was used. 144 nurses working in male, female surgical and orthopaedic wards, adult ICU and post-operative ICU, with mild and moderate level of low back pain and disability were selected, using consecutive sampling technique. The outcome variables were measured, using Numerical Pain intensity scale and Oswestry low back pain disability questionnaire. The intervention was comprehensive body mechanics, in which the researcher provided video assisted teaching on ideal body mechanics for 5 minutes followed by demonstration of lower back rehabilitation exercises by video for 15 minutes. Return demonstration and practice of lower back rehabilitation exercises was carried out by the nurses daily for 15minutes for 10 days, under the supervision of the researcher. On the 3rd day, a pamphlet was distributed followed by assessment of the effectiveness of the intervention on the 10th day. The collected data were analysed by SPSS 17 software, using Paired t-test Pearson correlation coefficient.
    Findings: There was a statistically significant difference before and after the intervention on pain (t =17.18; p
    Conclusion
    Comprehensive body mechanics is effective in reducing pain and disability among nurses with low back pain.

    Aims: In developing countries such as our country, most of the activities such as carpentry is performed manually and make workers exposure to inappropriate postures, which will increase the prevalence of Musculoskeletal Disorders (MSDs). One way to reduce these disorders is educational ergonomics interventions. The present study aimed at determining the effect of education on reducing ergonomic risk in traditional carpet weavers working in workshops in Golestan province, Iran.
    Materials and Methods
    This quasi-experimental study was conducted on 100
    employees in 54 traditional workshops in Golestan province of Iran in 2016. The studied population consisted of horsewomen carpet weavers who had at least one-year work experience and were selected based on simple random sampling method. The QEC method was used to assess the risk of musculoskeletal disorders and Nordic standard questionnaire was used to determine the frequency of symptoms of these disorders. The data were analyzed by SPSS 19, using paired sample t-test and Wilcoxon.
    Findings: In the pre-interventional stage, the greatest risk was related to the neck (71.0%) at high-risk level. This intervention was significantly reduced from interventional, and only 5.0% of subjects were at this level (p
    Conclusion
    Education can reduce ergonomic risk in traditional carpet weavers working in workshops
