Abstract
Introduction: One of the relatively common accidents in work place environments is Slips, Trips and Falls (STF) that can cause back injuries, sprains & strains, bruises, contusions, fractures, tears and even death. Aim of this study was slip risk assessment in different sections of a hospital in Shiraz University of Medical Sciences.
Materials and Methods: This cross-sectional study was done using Health and Safety Executive (HSE) Slip Assessment Tool (SAT). Prevalence of slip accidents were investigated using a questionnaire among 178 of hospital staffs. Data analysis was done using SPSS-20 software. Roughness coefficient was measured using Roughness Meter TQC-SP1560.
Results: Slip risk level in 5 sections including outside stairs, surgery, ICU and emergency admission was significant. The maximum and minimum slip risk was related to stairs and physiotherapy section respectively. The prevalence of slips incidents were reported 47.2 percent by healthcare workers.
Conclusion: The results of this study showed that the surface contaminant as well as method and frequency of surface cleaning are the most important effective factors on slip risk in the studied hospital.

Abstract
Background: Undesirable sit-up and deviation from desirable status is one of the factors affecting the health of students in the classroom. The purpose of this study was to evaluate the relationship between posture and musculoskeletal pain in boys 9 to 13 years old.
Methods: In this correlation study, the population consisted of all boy students in the primary city of Birjand. 60 students were selected as a sample group based on random-cluster method. Two video cameras were recorded 30 minutes of sitting position for every student. The anthropometric characteristics of subjects including height, weight, etc., were measured with a standard tool. The back and neck pain were collected using a modified Nordic questionnaire. Moreover, the kinovea software was used to analyze the flexion and rotation angle during sitting. The statistical calculations were applied by Kolmogorov-Smirnov normality test. The ETA correlation coefficient also was used to identify the relationship between variables. All statistical calculations performed using SPSS version 21.
Results: The result indicated significant relationship between bending and rotation angles with both neck and back pain (P≤0.05). Therefore it would be noticed that improper sitting can be accounted as a cause of muscle-skeletal pain in boy students based on bad postures during sitting.
Conclusion: According to the results, the posture of students while sitting in class is inadequate and harmful. Thus performing some intervention and education for students is recommended.

Abstract
Introduction: The purpose of this study was to study the relationship between ergonomic of educational equipments with anthropometrical parameters and upper extremity abnormalities in primary school girl students in Mashhad.
Methods: In this way, 14225 girl students were selected as statistical population, and then 375 subjects randomly were selected as a samples study. Some anthropometrical parameters as; popliteal height, popliteal-buttock length, elbow height from 90° angle, and shoulder height from setting position along with some educational equipments dimension used such as bench height, bench depth, desk height and width were measured. Moreover, upper extremity abnormalities including lumbar lordosis and thorax kyphosis were evaluated by flexible ruler. The related anthropometrical measures along with desk and bench dimensions also were determined in range of accepted limit (AL), over range of accepted limit and below range of accepted limit for each of benches and desks dimension. For statistical analysis the Chi-Square test in contingency tables, Cramer’s phi were used by SPPS version 16 (P<0/05).
Results: The result of this study indicated that the 81/8 percent of benches was higher than max accepted limit of the popliteal height, and 76/8 of students used some desks that was higher than max accepted limit (P<0/05). Bench depth was inappropriate for %100 of students and smaller than min accepted limit. Furthermore significant relationship observed between measure match bench height with popliteal height and abnormalities lordosis and kyphosis (p≤0/05).
Conclusion: The result of present study indicated that educational equipments of the Mashhad schools had no minimum ergonomic standard.

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: Musculoskeletal disorders and associated pains are represent significant and prevalent factors contributing to occupational injuries. The aim of this study was to investigate the effect of online upper cross syndrome-based exercises and the posture retraining on pain, disability, fatigue, and mental workload of experienced by dentists in Shahrekord city.
Methods: A total of 33 dentists were selected as the statistical sample and randomly assigned to three groups including, control (n = 11), Online National Academy of Sports Medicine (NASM) based corrective exercises (n=11), and posture retraining (n=11) groups. Baseline assessments were conducted, and outcomes were examined immidietly after the interventions. The experimental groups underwent the study interventions for six weeks, while the control group maintained their regular daily activities during this period. Primary outcome measure was pain, and secondary measures included disability, perceptual fatigue, mental workload, and quality of life. Within-group comparisons were analyzed using paired sample t-tests, and between-group comparisons utilized one-way analysis of variance.
Results: The results indicated that both exercise interventions positively affected pain, disability, perceptual fatigue, mental workload, and quality of life among dentists (P<0.05). Notably, correction of the upper crossed syndrome demonstrated a more significant effect compared to the posture retraining intervention (P<0.05).
Conclusion: The utilization of online NASM-based corrective exercises and posture retraining could have positive effects in reducing pain and disability and also improving the overall performance of dentists.
