The aim of this study was to investigate the normal range andchanges process of lumbar curve in students, both girls and boys, in the agegroup of 10 to 18 years.Methods: A total number of 1800 students (male and female), in the age group of10 to 18 years were selected to participate in the present study. The student sampleswere chosen from the different cities of the Isfahan province in a randomizedand clustered manner. Each age category included 100 male and female studentseach. The flexible ruler was used to measure the lumbar curve angle. The factorialANOVA method, in SPPS16, was used for data analysis with α=0.05.Results: The data analysis showed that the age changes factor and gender factorhave a significant effect on lumbar curve changes in the level of P<0.05. However,the interaction between gender and age was not significant (P>0.05). This meansthat the changes process is similar in both gender groups.Conclusion: The lumbar curve angle is generally higher in girls. Moreover, thisangle increases in both genders as age increases to 18 years. The extent of thelumbar curve exceeds the normal limit in girls after 13 years of age with the onsetof puberty, which means that girls in this age group need additional attentionfrom the concerned authorities in order to prevent spinal abnormalities.}, keywords = {Lumbar Curve,Student,Abnormality,Flexible Ruler}, url = {https://jrsr.sums.ac.ir/article_41115.html}, eprint = {https://jrsr.sums.ac.ir/article_41115_ec7d9c9f2fb96df7ba31c6c304c51277.pdf} } @article { author = {Arabpour, Maryam and Nakhshab, Mahbube and Abdolrashidi, Najme and Molaiefard, Mahtab and Bakhtyari, Shima and Ansari, Hossein}, title = {Comparing Narrative Microstructure between Bilingual Balochi-Persian and Monolingual Persian Preschoolers}, journal = {Journal of Rehabilitation Sciences & Research}, volume = {4}, number = {2}, pages = {36-40}, year = {2017}, publisher = {Shiraz University of Medical Sciences}, issn = {2345-6167}, eissn = {2345-6159}, doi = {10.30476/jrsr.2017.41116}, abstract = {Background: To date, with rapid increase of bilingual children, more attention about different patterns of the bilingual children narratives is needed.

Children’s story telling was audio-recorded and analyzed using the Persian-NAP (Narrative Assessment Protocol) guidelines. Results: All of the NAP indicators include of group structure, phrase structure, modifiers, noun and verbs didn’t show significant difference between monolingual and bilingual children (0.06≤p≤0.5).Conclusion: We didn’t find different performance in the five NAP indicators between bilingual and monolingual children. It may be suggested that the different patterns of creating phrases and sentences in two languages don’t affect the grammatical use of them in second language. }, keywords = {narrative,microstructure,bilingualism,Balochi language}, url = {https://jrsr.sums.ac.ir/article_41116.html}, eprint = {https://jrsr.sums.ac.ir/article_41116_bc9ce640bad11fa330827e899739bf3a.pdf} } @article { author = {Beyranvand, Ramin and Moradi, Ali and Fatahi, Faraj and Mirnasouri, Rahim}, title = {Assessment and Comparison of Rapid Weight Loss Methods and its Complications in Various Weight Groups of Adult Elite Wrestlers}, journal = {Journal of Rehabilitation Sciences & Research}, volume = {4}, number = {2}, pages = {41-46}, year = {2017}, publisher = {Shiraz University of Medical Sciences}, issn = {2345-6167}, eissn = {2345-6159}, doi = {10.30476/jrsr.2017.41117}, abstract = {Background: The prevalence of rapid weight loss methods among wrestlers has raised concerns about the health and performance of these people. The purpose of this study was to assessment and comparison of rapid weight loss methods and its general effects in various weight groups of adult elite wrestlers.Methods: In this analytical-descriptive study, the sample consisted of 40 elite wrestlers with mean age of 24.77 years (12 lightweight, 16 middleweight and 12 heavyweight wrestlers), who all had an experience of playing in the national team of the Islamic Republic of Iran for at least three years. The methods and the effects of rapid weight loss were evaluated using the validated Persian version of the Oppliger questionnaire (ICC>0.65). Finally, Kruskal-Wallis and Chi-square tests were used to examine differences between the 3 weight groups using SPSS 21 (p≤0.05).Results: The results of this study showed that the most commonly used methods for weight loss in all three weight groups included increased exercise (79%) and Intense dieting (76.7%). The results also showed that dizziness (74.4%), muscle cramp (69.7%) were the most frequent complications observed in various weight groups following rapid weight loss. Moreover the results showed there was no significant differences between the methods of rapid weight loss and its complications in various weight groups of wrestlers (P>0.05).Conclusion: According to the results of this study it seems that the methods of rapid weight loss and its complications are similar in various weight groups of adult elite wrestlers. Therefore it seems necessary that adequate information about appropriate weight loss methods should be provided for them in order to prevent the complications of rapid weight loss.}, keywords = {Wrestling,Rapid Weight Loss,adult,Elite}, url = {https://jrsr.sums.ac.ir/article_41117.html}, eprint = {https://jrsr.sums.ac.ir/article_41117_1acce12939bdcb95799f1f0cd3312b68.pdf} } @article { author = {Hosseini, Pegah and Karimi, Mohammad Taghi and Abnavi, Fatemeh and Golabbakhsh, Marzieh}, title = {Evaluation of the efficiency of Minerva collar on cervical spine motions}, journal = {Journal of Rehabilitation Sciences & Research}, volume = {4}, number = {2}, pages = {47-52}, year = {2017}, publisher = {Shiraz University of Medical Sciences}, issn = {2345-6167}, eissn = {2345-6159}, doi = {10.30476/jrsr.2017.41118}, abstract = {Background:  Various types of cervical collars have being used to immobilize the cervical spine. There was no information regarding the effectiveness of Cervicothoracic collars (Minerva) on restriction of motions in cervical spine. Therefore, the purpose of this study was to evaluate the immobilization achieved follow the use of Minerva collar in cervical and Cervicothoracic spine. Methods: Twenty healthy subjects (10 females and 10 males) were recruited in the study with no history of pain, deformity and surgery in spine. A motion analysis system was used to record the motions of cervical, upper thoracic and cervicothoracic in flexion, extension, lateral bending and rotation with and without Minerva collar.Results: The motion restriction of the upper cervical spine obtained with Minerva collar varied between 86.32 and 90%. The range of flexion/extension of cervical and cervicothoracic parts decreased by 27.35 and 56.32%, respectively follow the use of Minerva collar. The flexion/ extension range of motion of this segment decreased by 77.85 and 63.25%, respectively between occiput and T12.Conclusion: The maximum restriction of motion with Minerva collar was achieved in cervical spine.

A Qualisys motion system capture with seven cameras and a Kistler force plate were used to record kinematics and kinetics variables of walking. The forces applied on knee, hip and L5-S1 joint contact forces (JCF) were calculated by using Open-SIM software. SPSS software was used to analyze data at an alpha set point of 0.05.Result: The propulsive and second peaks of ground reaction forces applied on sound leg were significantly higher than prosthetic leg (p<0.05). Although the forces applied on hip, knee and L5-S1 joint in the sound leg were higher compared to prosthetic leg, the interaction between side and joint factor was not significant (p>0.05).Conclusion: The results of this study showed that the meaningful JCF applied on the sound leg were more than that of prosthetic leg. Insignificant increases in JCF on the sound leg during life can create cumulative forces on knee and low-back and endanger these joints at the risk of knee OA and chronic low-back pain. Balanced forces applied on sound and prosthetic leg is important, if this is the case, so indicating using a proper usage of socket pin and prosthetic feet which may have beneficial impact on sound side loads.}, keywords = {Prosthetic,Below Knee Amputation,Kinematics,Kinetics,Gait,Joint Contact Force,Open-SIM}, url = {https://jrsr.sums.ac.ir/article_41119.html}, eprint = {https://jrsr.sums.ac.ir/article_41119_645355ebea0a1a0b684a3c4cd662877b.pdf} }
