    Aims

    Health care providers working in comprehensive health centers are considered as one of the main computer users and are subject to musculoskeletal disorders caused by computer work. This study was conducted to determining the effect of educational intervention based on the ergonomic principles of working with computers on knowledge, attitude and practice of health care providers working in comprehensive health centers of Sirjan , Iran. Instrument &

    Methods

    This study was performed with 110 health care providers working in comprehensive health centers of Sirjan. Census method was used for sampling. A manmade questionnaire was used to assess the effect of education on the improvement of behaviors preventing the MSD caused by working with computers. The training program in the intervention group consisted of three one-hour sessions. Data were collected at the beginning and 3 months after the intervention; and they were analyzed using spss16 software and Chi-square, independent T-test, and Wilcoxon and Mann-Whitney tests.

    Findings

    According to the results, despite the homogeneity of the two groups in terms of all the variables studied, the interventional group, after education, had a significant difference in knowledge, attitude and practice regarding observing the ergonomic principles of work with computers in comparison with the control group (p < 0.0001). Furthermore, in the intervention group three months after the training, there was a significant difference in the mean score of two variables of attitude and practice.

    Conclusion

    The results of this study showed that educational programs based on ergonomic principles of working with computers can promote behaviors preventing the MSD in computer users. Therefore, educational interventions are recommended in order to improve the behaviors preventing musculoskeletal disorders.

    Aims

    Postural abnormalities cause dysfunction. In this regard, lower extremity disorders such as flat- foot play a major role in creating lower extremity disorders. The present study evaluates the effect of a course of selected corrective exercise on the balance and performance of adolescent girls with a flat foot.

    Instruments & Methods

    Subjects in this study included 30 students within the age range of 9-10 years old with flat -foot deformities who were randomly selected and divided into two groups of corrective exercise (age: 11.60 ± 1.02 years, height: 148.46±10.29 m, weight: 47.40±11.69 kg and body mass index: 21.42±11.92) and control (age: 11.40±0.95 years, height: 148.46±12.67 m, weight: 47.46±12.28 kg and body mass index: 21.37±4.28).

    Findings

    Demographic data were collected through a questionnaire and Navicular drop method was used to assess flat- foot deformity. Descriptive statistics were used to determine the frequencies, central indices, and dispersion in the form of tables and graphs, and multivariate analysis of covariance was used to investigate the intergroup differences in research variables. The results showed that corrective program had a significant effect on functional tests and static balance with open and closed eyes (p<0.01).

    Conclusion

    This study showed that corrective exercises were effective in improving balance and function of the studied-participants. Hence, it is suggested that therapists use different exercises related to the trunk and lower extremities in the form of corrective program to improve female adolescents’ deformities.

    Aims

    Evidences support association between obesity and Low Back Pain (LBP). The purpose of the present study is to explore related factors of lBP in some employees working at Deputy of health of Guilan University of Medical Sciences.

    Instrument & Methods

    This study was a cross sectional study. A total of 100 employees working at deputy of health of Guilan University of Medical Sciences and were selected through nonrandom purposive sampling method. The research tools were Quebec Back Pain Disability Scale (QDS) and Visual Analogue Scale (VAS) . Statistical descriptive/analytic methods were used to analyze data through SPSS version 23.

    Findings

    In total 100 employees with mean age 43.84 ±8.44years took part in the study. Of these participants, 68 employees were female (68%) and 32 employees were male (32%).
    The findings from this study indicated that most of the studied participants were suffering from moderate pain. This study also showed that there was a significant association (P < 0.05) between LBP and high BMI.

    Conclusion

    This study verified that increased Body Mass Index (BMI) is associated with LBP and disability among employees. Therefore, designing educational programs with emphasis on reducing BMI through increasing physical activity and healthy diet is strongly recommended.

    Aberrant subclavian artery is a rare anomaly among all anomalies related to aortic arch. In some cases kind of aneurysm named Kommerell diverticulum, originated from right subclavian artery and left aortic arch and the opposite, left subclavian artery association with right aortic arch [1]. Right Aortic Arch(RAA) is a rare congenital anomaly with 0.5 to 1% of normal population. Almost half of the Cases associated with left aberrant subclavian artery and in some, aneurysmal changes in the origin of the artery is inevitable [2]. RAA is categorized in three groups : 1.RAA with left aberrant Subclavian artery2.RAA in mirror type.2.RAA with isolated LSA, which RAA with ILSA is a most rare by 0.8 % prevalence [3]. Left aberrant subclavian artery (LASA) is an anatomical variant of right aortic arch which is actually dispart from the RAA as a last branch and usually pass behind esophagus to the left upper limb. However, RASA associated with LAA is more common (0.5_2% of population) the LASA originated from RAA(0.05_0.1) [4]. Kommerells diverticulum or KD, is defined as a aneurysmal form of ASA or descending aorta in proximal part [5] .KD is a rare condition usually accompany RASA more than LASA [6, 7]. Up to now, few cases has reported. Burckhard F Kommerell was the first one who introduced kommerell in 1936 [8]. Anomalies of aortic arch not necessary influence health condition in childhood and some become symptomatic in adolescence [9]. These aneurysms could be strong threatening for some circumstances like dissection, rupture, emboli to distal parts, compression to adjacent or organs [1].
