Abstract
Background and Objectives: Musculoskeletal disorders and low quality of life are the most common problems among paddy farmers in the world. Paddy farmers are exposed to inappropriate postures, long working hours and stressful environmental conditions. The aim of this study was to compare different farming methods of rice cultivation (traditional and semi-modern) on the prevalence of musculoskeletal disorders and life quality of paddy farmers.
Methods: This descriptive-analytical study was conducted in rice fields with 150 paddy farmers as a sample group (100 traditional paddy farmers and 50 semi-modern paddy farmers). Musculoskeletal disorders and quality of life were assessed using the Nordic questionnaire and the Lancashire Quality of Life Profile, respectively.
Results: The prevalence of musculoskeletal disorders in the neck, lower back and shoulders is higher in traditional paddy farmers compared to farmers who work in semi-modern rice cultivation system. Present results demonstrated that there was no significant difference between various rice cultivation methods and musculoskeletal disorders on life quality. Furthermore, different farming methods of paddy cultivation have no significant effect on paddy farmers' life quality.
Conclusion: The prevalence of lower back musculoskeletal disorders among paddy farmers portrays the consequence from long-term exposure to inappropriate posture from strenous activity.

Abstract
Objectives: Work-induced musculoskeletal pain disorders are among the most common problems among workers. This study aimed to compare fatigue and trunk and neck postures during work in tailors with and without nonspecific chronic neck pain.
Methods: In this cross-sectional study, 30 sewing machine operators participated voluntarily and were divided in two groups of people with (15 persons) and without (15 persons) chronic nonspecific neck pain. The craniovertebral, cranial, and shoulder angles were calculated three intervals (at the start of work, after 2 hours of continuous work, after 4 hours of continuous work) using the photogrammetric method. Borg scale was used to examine work-induced fatigue. A one-way repeated measure analysis of variance at the significance level of 0.05 was used for data analysis.
Results: There were significant differences in craniovertebral, cranial, and shoulder angle changes (P < 0.001) between the two groups while working. Postural trunk and neck changes were more evident in the nonspecific chronic neck pain group. However, there were no significant differences in terms of fatigue levels between the two groups (P = 0.639).
Conclusion: The upper trunk related posture among workers with nonspecific chronic neck pain may be more negatively affected during work. So it is suggested that maintaining proper posture should be more emphasized among these workers.

Abstract
Objectives: Ankle sprain leads to a decrease in proprioception and awareness of the sense of motion with motor consequences. On the other hand, damage to this joint is an important factor in affecting balance and consequently re-injury. Strengthening the factors that help maintain balance and posture, can be a basic strategy in the treatment of balance and postural problems, as well as injuries.
Methods: In this quasi-experimental study, 30 patients with chronic ankle instability were randomly divided into experimental and control groups. Both groups were pre-tested and the experimental group performed core stability exercises against gravity for six weeks. Post-test was taken again from both groups. Data were analyzed using one-way analysis of covariance. Statistical operations were performed at a significant level of α ≤ 0.05.
Results: Postural control index in the experimental group was higher in the first position and lower than the other in the sixth position. The mean of the postural control index in the experimental group was significant compared to the control group (α ≤ 0.05).
Conclusion: Performing exercises for core stability or training on unstable surfaces deploying sensory receptors is likely to cause the muscles to be more actively involved and the central nervous system to receive more appropriate and effective stimuli from the nerves of different sensory receptors, and thus this exercises improve postural stability.

Abstract
Objectives: Inappropriate sitting posture on bench can contribute to pain and musculoskeletal disorders in students. Hearing and vision disabilities may be the cause of inappropriate sitting postures among students. Therefore, the aim of the present study was to compare the risk of musculoskeletal disorders in normal and students with hearing abnormalities in Ilam city.
Methods: Twenty students with hearing abnormalities (case) and 40 students with normal hearing (control) from primary schools in Ilam city of both genders were randomly included in the study. The worst recorded sitting posture of students on the bench was evaluated by the RULA method. Digimizer software was used to survey the body angles of the students while sitting on the bench. The used for analyzing the obtained data in 95% confidence interval.
Results: The results of posture evaluation showed that there was a significant difference in rula scores between case and control groups (P = 0.001). Deviation from the natural angles of the body in the case groups was more than the control group (P < 0.001), which has a direct and significant relationship with the increased risk of musculoskeletal disorders.
Conclusion: Musculoskeletal disorders possibility incidence were more common in students with hearing abnormalities compared to typical students which was due to an increase in deviation from the natural angles of the body and inappropriate postures. Given the limitation of the sample size, the present study recommends further research with the same goal and encourages interventional studies to correct the posture of hard of hearing students.

Abstract
Objectives: Chronic neck pain is one of the most common musculoskeletal disorders that has a great impact on people's quality of life, health, and work efficiency. Due to the high costs of drug treatments, the search for simple and low-cost treatment solutions is inevitable. Stretching and tissue release techniques are effective solutions for correcting skeletal-muscular disorders. Therefore, this study aimed to investigate their effectiveness in controlling pain and improving the performance of people suffering from non-specific chronic neck pain.
Methods: In this semi-experimental study with parallel groups and pre-test-post-test design, 39 patients with non-specific chronic neck pain with an average age of 25 to 45 years, in a non-random and available form, were selected from the office workers. Individuals were randomly assigned into three groups of traction stretch, release, and control, and received interventions for six weeks. At the beginning and after the completion of the interventions, pain intensity, qualitative fatigue, and quality of life were evaluated using the visual measure of pain, multidimensional fatigue questionnaire, and SF36 questionnaire, respectively. To compare the averages, one way ANCOVA a mixed analysis of variance test was used.
Results: Intra-group comparisons showed that pain intensity, quality of life, and fatigue improved significantly in both intervention groups (P<0.05). Stretching and release exercises both had a significant effect on improving the variables (P<0.05). However, the results of the release exercises group were more significant.
Conclusion: Six weeks of releasing and stretching techniques in non-specific chronic neck pain patients reduces pain and fatigue and increases their quality of life.

Abstract
Objectives: Work-related musculoskeletal Disorders (WMSDs) are the most significant challenges in both developing and developed countries, affecting the majority of individuals throughout their lives. Considering the detrimental effects of musculoskeletal disorders on the productivity and general health of employees, this research utilizes the Cornell Musculoskeletal Disorder Questionnaire (CMDQ) to develop an intelligent model for assessing and predicting the levels of musculoskeletal disorders.
Methods: In this descriptive-analytical study, 810 employees from five organizations (in four occupational categories, including administrative, technical, production, and services) completed the CMDQ voluntarily. After collecting the questionnaire and performing relevant statistical analyses, data normalization and clustering based on the K-Means method were used to determine levels of musculoskeletal disorders. Finally, the multilayer perceptron artificial neural network was trained to predict the levels of musculoskeletal disorders; moreover, the criteria of precision, accuracy, recall, and F1-score were used to evaluate the proposed model.
Results: The performance of the proposed model in predicting the levels of musculoskeletal disorders is presented in two scenarios (use and non-use of the Synthetic Minority Oversampling Technique (SMOTE) method) based on the evaluation criteria provided. The accuracy, precision, recall, and F1-score values were 0.724, 0.709, 0.756, and 0.720, respectively. The appropriate accuracy and precision in the proposed model indicate its capability to identify the levels of musculoskeletal disorders in individuals and help healthcare professionals take necessary measures to prevent and predict them.
Conclusion: This study employs the CMDQ questionnaire and artificial intelligence to analyze musculoskeletal disorders in the workplace. The proposed model demonstrates significant accuracy and precision compared to similar studies. The results indicate that this model can be utilized to identify and predict musculoskeletal disorders in organizational employees, offering the potential to expedite the identification process and reduce costs.
