Journal Article 2014 12 30 Background and Aim: The present study was carried out to study the role of static balance and anthropometric indices in the shooting sports and its impact on the performance of the shooters with the aim of informing the shooting sports specialists and correcting weaknesses in male and female shooters. <br />Materials and Methods: Anthropometric characteristics, weight, height (standing and sitting positions), two hands, arm length, leg length, the actual length of the foot, knee width, resting and contracting arm circumference, arm circumference, hip circumference, the mid-thigh, the knee, the leg, the ankle, BMI, percent body fat, WHR, and two tests for balance, i.e. Sharpened Romberg and stork, were evaluated for 32 shooters (16 women and 16 men from among the pool of 45 shooters of the National Shooting Team) and 32 controls (16 females and 16 males). <br />Results: The results showed that comparison of the stork balance with anthropometric indices revealed significant difference only in weight variable in female participants and the width of the knee in male participants. No sifnificant relationship was observed between Sharpened Romberg test indices and any of the anthropometric indices in females (except for weight) and males either. Shooters were observed to have better balance compared with that of the control group. Moreover, comparison of anthropometric indices of the adult male and female elite shooters showed that there is a significant difference among all the anthropometric indices. <br />Conclusion: It can be concluded that the Iranian elite shooters have a significantly higher static balance in comparison with that of the control group.

Journal Article 2014 10 16 Background and Aim: Development of phonological awareness is essential for literacy and it is a vigorous predictor of reading. Meanwhile, bilingualism is a factor that affects cognitive and language skills and consequently reading and writing skills, thus it seems necessary to do more studies to understand the effect of this social factor on educational performance. Considering the prevalence of bilingualism in Iran, the aim of the present study was to investigate the effect of school training on phonological awareness of Lak-Farsi bilingual 6 year old children. <br />Materials and Methods: The current study is a quasi-experimental study using a descriptive analytic method. Participants were 30 bilingual six-year-old lak-farsi speaking children randomly selected from among the children who took part in the elementary school entrance measurement project in Noorabad and Aleshtar city. In the current survey, we used the Soleimani-Dastjerdi validated phonological awareness tool. The children’s performances were evaluated again after three months. <br />Results: The findings indicated that the differences of the mean scores between test-retest were significant in all the skills (p≤0.001). <br />Conclusion: The differences between test-retest scores emphasized the importance of school training for bilingual children. Due to the interconnection between phonological awareness and literacy, authorities should seriously support the training programs for bilingual children in kindergartens and preschools.

The prevalence is over 2.9% in women and 6% in men. The disease has symptoms such as paresthesia, tingling and numbness, pain, and weakness in the thenar. The current treatment of carpal tunnel syndrome include non-surgical or care treatment and surgery. Carpal tunnel release surgery is recommended when the disease aggrevates and protective treatments are not efficient anymore. After surgery, scar adhesions, complex recurrent pain syndrome, sensitivity, inflamed scar area, and pain in the thenar and hypothenar areas may be observed for up to 8 weeks or more. In order to reduce and to prevent the development of complications after surgery, guidelines and recommendations are provided that are specific to Occupational Therapy; however, due to the lack of accurate information on when occupational therapy should start after surgery and considedring the importance of this issue in improving performance, reducing the severity of symptoms, and helping the patients return to work faster, the present study was conducted to examin the effect of early occupational therapy to improve performance and to reduce the severity of symptoms caused by carpal tunnel release surgery.  <br />Materials and Methods: The present study was a clinical trial and the population consisted of the patients reffering to Akhtar hospital with a diagnosis of idiopathic carpal tunnel syndrome and thus candidates for surgery. A total of 20 patients with an average age of 35-65comprised the final particiapnts of the study. Participants were divided into two groups. The experimental group, besides the common care advised by their surgeons, received occupational therapy with the same protocol during the first week after the surgery. Evaluations carried out for both groups prior to the surgery and one month after the surgery included hand function, symptoms severity by Boston questionnaire, and return to work time. <br />Results: The statistical anlysis of the findings revealed that occupational therapy program in the first week after a CTS surgery resulted in a decrease in symptoms severity (P=0.003), and a decrease in return to work time (P=0.001). <br />Conclusion: Based on the findings, although both patient groups with carpal tunnel syndrome showed improvement in symptoms and functioning after surgery, early occupational therapy in the experimental group was shown to be significantly effective in decreasing symptoms severity and the return to work time compared with that in the controls. So, early occupational therapy on the patients with carpal tunnel syndrome is recommended. Background and Aim: One of the most common hand diseases is the carpal tunnel syndrome.

The purpose of the spresent study was to investigate the immediate effect of WBV on maximumisometric contraction and upper limb EMG indifferent contraction forces. <br />Materials and Methods: In 15 young healthy men, dominant biceps randomly underwent isometric contaction with supination of forearm and 90 degrees of elbow flexion while receiving no WBV or WBV with a frequency of 50 Hz and low amplitude (4 mm) for 60 seconds (i.e. two thirty-second phase with an interval of 20-second-rest) in three different modes: without EL, with an EL of 10% of primary MVC, and finally with an EL of 20% of primary MVC. In the meantime, EMG activity of the muscle was recorded and once the whole exercise protocol was terminated, MVC was measured and its EMG activity was recorded simultaneously with MVC. <br />Results: WBV without EL showed a significant increase in biceps MVC compared with no WBV and no EL(P=0.006), wheras in WBV the comparison of an EL of 10% of primary MVC and that of 20%, despite rendering higher rate of MVC, is not statistically significant. On the other hand, WBV without EL revealed a significant improvement in biceps RMS (P=0.001). The same was true in WBV with an EL of 20% of MVC (P=0.032). The rate of ∆FMED with WBV or without WBV, and with an EL of 20%, was statistically more significant than without WBV, with an external load of 10%, and this significancy with vibration was P=0.011 and without vibration was P=0.016. Meanwhile, ∆FMED was significant with WBV and with an external load of 20% of MVC compared with WBV and 10% of MVC (P=0.023). <br />Conclusion: It seems that a single session of WBV reults in an immediate increase of MVC and EMG of biceps bracheiand applying ELs of 10% and 20% of MVC with WBV did not significantly increase in the present study, but it leadsto more increase of MVC and EMG. Also, the effect of an EL of 20% of MVC in this increase is more tangible than 10% of MVC.

Tehran. Iran Seyed-Ali Emami Hashemi MSc Student in Corrective Exercises and Sport Injury, University of Tehran. Tehran. Iran Journal Article 2015 04 13 Background and Aim: Forward head posture (FHP) is one of the most common faulty postures which leads to improper organization of the neck muscles and limitening of pulmonary capacity and whereby breathing becomes difficult. The goal of the current study was to evaluate the effect of 4 weeks of corrective exercises on forward head angle (FHA) and spirometry parameters of college girl students. <br />Materials and Method: Thirty female students from the University of Tehran who suffered from FHP were randomly divided into experimental and control groups. The subjects performed the exercises twice a day for 4 weeks. The forward head angle and spirometry parameters were measured before and after the treatment. Collected data were analyzed using the T-dependent test via SPSS (version 21). P-value was set at 0.05. <br />Result: After the intervention, the experimental group had a significant reduction on forward head angle (p<0.05). Also, significant differences were observed in Maximal Voluntary Ventilation (MVV) (p<0.05). No significant changes were observed in Forced Expiratory Volume in One second (FEV1), Peak Inspiratory Flow Rate (PIFR), and Peak expiratory Flow Rate (PEFR) (p>0.05). <br />Conclusion<em>:</em> The data revealed that corrective exercise is a simple and non-invasive method to decrease FHA and can be helpful to increase MVV parameter. Background and Aim: Forward head posture (FHP) is one of the most common faulty postures which leads to improper organization of the neck muscles and limitening of pulmonary capacity and whereby breathing becomes difficult. The goal of the current study was to evaluate the effect of 4 weeks of corrective exercises on forward head angle (FHA) and spirometry parameters of college girl students. <br />Materials and Method: Thirty female students from the University of Tehran who suffered from FHP were randomly divided into experimental and control groups. The subjects performed the exercises twice a day for 4 weeks. The forward head angle and spirometry parameters were measured before and after the treatment. Collected data were analyzed using the T-dependent test via SPSS (version 21). P-value was set at 0.05. <br />Result: After the intervention, the experimental group had a significant reduction on forward head angle (p<0.05). Also, significant differences were observed in Maximal Voluntary Ventilation (MVV) (p<0.05). No significant changes were observed in Forced Expiratory Volume in One second (FEV1), Peak Inspiratory Flow Rate (PIFR), and Peak expiratory Flow Rate (PEFR) (p>0.05). <br />Conclusion<em>:</em> The data revealed that corrective exercise is a simple and non-invasive method to decrease FHA and can be helpful to increase MVV parameter. https://medrehab.sbmu.ac.ir/article_1100228_1826f49cf7bcf0d47f7e916e79983f05.pdf

It has an important role in medical sciences as the students studying these branches of science are getting ready to attend clinical work. Critical thinking helps to convey psychomotor skills from class to clinic. In the present study, we aimed at reviewing medical sciences students’ critical thinking skills and the effect of the universities' curriculums on them. <br />Materials and Methods: Databases of PubMed, ScienceDirect, Magiran, SID, Iranmedex, and Iranian medical education magazines were searched from 2000 to 2014. The terms Critical Thinking, Students, curriculum, Medical Sciences, and the combinations were used to search these databases. <br />Results: From among almost 35 relevant studies, 16 studies were selected. Based on their topics, the studies (except for the systematic review and Delphi study, which are discussed separately) were divided into three groups: 1) The studies that examined disposition to critical thinking, 2) The studies that examined critical thinking skills, and 3) The studies which examined both disposition and skills. <br />Conclusion: Facilitating students’ critical thinking must be a priority in education and new teaching methods should be used by instructors in the class. Also, we need more extensive studies to explore the barriers of improving critical thinking in students of medical sciences.

Despite the prevalence of PFPS, its etiology is not clearly known and has been reported to be multifactorial. Managing patients with PFPS is often challenging, in part because of a lack of consensus regarding its etiology and treatment. Electromyography (EMG) is a well-known method to study the etiology of PFPS. The aim of the present study was a systematic review of studies conducting electromyography of knee muscles in people with and without PFPS. <br />Materials and Methods: Databases of PubMed, ScienceDirect, and Google Scholar were searched for studies published in English between 2000 and 2014. The terms: PFPS, EMG, muscle imbalance, motor control, vastii muscles, and knee muscles as well as the combination of these terms were used. <br />Results: Among almost 35 relevant studies, 9 studies were selected. Based on the muscles, the studies were divided into two groups: 1) The studies that assessed vastii muscles, and 2) The studies that compared vastii and hamstring muscles. <br />Conclusion: Studies had used diverse EMG signal processing and testing protocols. The findings tended to support the notion that alteration in the electrical signal of the knee muscles is founded in individuals with PFPS, but the pattern of this alteration is still a matter of question. Due to the varietry of studies and their results, it can be concluded that the evidence, although existant, is not convincing yet.
