Email: zrezaeian@rehab.mui.ac.ir; zrezaeian@yahoo.comJournal Article20160302Background: Subjects with knee osteoarthritis typically have higher knee adduction moment. Current research efforts are mainly focused on therapeutic procedures that potentially may modify disease progression. This preliminary study was designed as a single blind (examiner) randomized control trial to investigate the impact of conventional physical therapy on pain, and knee joint load in subjects with moderate knee osteoarthritis.Methods: Twelve participants diagnosed with moderate knee OA were randomly assigned into control and intervention groups. Three-dimensional knee kinematic and kinetic data were recorded during the gait before and after 10 sessions of conventional physical therapy. In addition, pain intensity was evaluated by visual analog scale and pain subscale of KOOS questionnaire. The control group did not receive any intervention during the same period. Gait parameters were analyzed within and between groups using nonparametric tests.Results: There was a significant difference between groups in baseline KOOS-pain Score and ML knee force (P =0.048 and P=0.01). Immediately after ten sessions of physical therapy the initial (first) peak of knee adduction moment was significantly (P=0.03) lower than that of the control group while the first and second peak of knee AP velocity were significantly (P=0.02, P =0.01 respectively) higher. In the intervention group, the second peaks of vertical and anteroposterior (AP) knee forces were strongly correlated with the pretest KOOS-pain Score (r =0.99 and r =0.98, P<0.001). Therefore a multivariate general linear model was adopted with adjustment to baseline KOOS-pain. By this adjustment, 51% alleviation of VAS pain score and 81% decrement of first peak of knee adduction moment in comparison to control group was statistically significant (P=0.02, P=0.03 respectively).Conclusion: It seems that ten sessions of conventional physical therapy may modify knee joint load in subjects with moderate knee osteoarthritis. Further research is recommended.Shiraz University of Medical SciencesJournal of Rehabilitation Sciences & Research2345-61672420151201Scapular Kinematic Measurement in Subjects with and without General Hypermobility Syndrome Using Motion Analysis System: A Reliability Study80864108010.30476/jrsr.2015.41080ENSalmanNazary-MoghadamAssistant Professor in Physiotherapy, Department of Physiotherapy, School of Paramedical Sciences, Mashhad University of Medical SciencesAfsoonNodehiAssociate Professor in Physiotherapy, Department of Physiotherapy, University of Social Welfare and Rehabilitation Sciences, Tehran, IranAmir MasoodArabAssociate Professor in Physiotherapy, Department of Physiotherapy, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran.AfsanehZeinalzadehPhD, PT, Department of Physiotherapy, Faculty of Rehabilitation Sciences, Tehran University of Medical Sciences and Health Services, Tehran, IranHosseinNegahbanAssociate Professor in Physiotherapy, Department of Physiotherapy, School of Paramedical Sciences, Mashhad University of Medical Sciences, Mashhad, IranJournal Article20151210Background: The purpose of the present study was to examine the reliability of scapular kinematic measurements using motion analysis system in subjects with and without General Hypermobility Syndrome.Methods: A methodological study was designed to assess the reliability of scapular movement measurement in two groups of females with and without General Hypermobility Syndrome. Upward rotation, superior- inferior translation, medial-lateral translation, posterior tilt and medial rotation were measured during arm elevation in both frontal and sagittal planes using a motion analysis system. Intraclass Correlation Coefficient (ICC) and Standard Error Measurement (SEM) were used to assess intra-rater within-day reliability of the scapular kinematics measurements in both groups.Results: The ICC values ranged from 0.72 to 0.98 and 0.69 to 0.98 for GHS and healthy subjects, respectively. In addition, the results showed that SEM for scapular rotation and translation are always lower than 1.72º and 1.65 cm, respectively.Conclusion: Motion analysis system could be used as a reliable method to measure the scapular kinematics in subjects with and without General Hypermobility Syndrome.Shiraz University of Medical SciencesJournal of Rehabilitation Sciences & Research2345-61672420151201The Comparison of the Effects of Selective Pilate’s and Williams’ Exercises on Pain and Flexibility in Men with Chronic Non-Specific Low Back Pain: A Randomized Clinical Trial87924108110.30476/jrsr.2015.41081ENRaminFallahzadehSchool of Rehabilitation Sciences of Shiraz University of Medical SciencesSorayaPirouziSchool of Rehabilitation Sciences of Shiraz University of Medical SciencesShohrehTaghizadehSchool of Rehabilitation Sciences of Shiraz University of Medical SciencesJournal Article20160113Background: Chronic non-specific low back pain is a common disorder that often has no clear mechanism. Exercise therapy is an effective and safe method for treatment of chronic musculoskeletal disorders such as back pain. Pilate’s and Williams’ exercises are two types of distinct exercises used for the treatment of back pain, but there is no evidence for the advantage of these two exercises in literature. Therefore, the aim of this study was to investigate and compare the effects of selective Pilate’s and Williams’ exercises on the back flexibility and back pain in men with chronic non-specific low back pain.Methods: Forty men with chronic non-specific low back pain were divided into two equal groups who participated in 10 sessions (during two weeks) of treatment program. Patients in group 1 received an electrotherapy treatment followed by selective Pilate’s exercises. Patients in group 2 received Williams’ exercises after the same electrotherapy treatment. Back flexibility and pain level were measured before and after the interventions. Also, a pain follow up was done four weeks later. Statistical analysis was done using Mann-Whitney, Wilcoxon, mixed ANOVA and Friedman tests.Results: The results showed that the back flexibility increased and pain decreased in both groups (P = 0.001). Selective Pilate’s exercises were more effective in enhancing the back flexibility and reducing back pain (P = 0.001).Conclusion: Comparison of these two types of therapeutic exercises showed that selective Pilate’s exercises are more effective in treatment of patients with chronic non-specific low back pain.Shiraz University of Medical SciencesJournal of Rehabilitation Sciences & Research2345-61672420151201The Prevalence of Specific Language Impairment in 5-year-old Persian-Speaking Children in Shiraz City of Iran – 201593964108210.30476/jrsr.2015.41082ENMohammad MajidOryadi-ZanjaniDepartment of Speech Therapy, Rehabilitation School, Shiraz University of Medical Sciences, Shiraz, IranMaryamVahabDepartment of Speech Therapy, Rehabilitation School, Shiraz University of Medical Sciences, Shiraz, Iran0000-0002-1913-8232JavadRasouliUrmia Universiry of Medical Sciences, Urmia, IranRaziyeAshkbousiNesaBarpooshJournal Article20150726Background: Specific Language Impairment (SLI) is one of the most common developmental problems resulting in referral to speech therapy clinics in the preschool years. A number of studies have been conducted to determine the prevalence of SLI in different populations. However, the prevalence of childhood language disorders in Iranian population is unknown because of the limited epidemiologic studies in the field. The aim of this study was therefore, to estimate the prevalence of SLI in 5-year-old Persian-speaking children. Methods: This research was an epidemiological study which conducted in a three-month period in the spring of 2015 in Shiraz. The sample size was 180 children aged 5 years old including 95 boys and 85 girls whom recruited from 12 preschool centers of 9 urban areas in Shiraz by stratified sampling. The EpiSLI system was used to diagnose SLI. The Persian version of Test of language Development (TOLD-P: 3) was employed to evaluate the children’s oral language skills. A number of descriptive statistics were calculated. In addition, Chi-square test was used to analyze the correlation between the prevalence of SLI with sex and area. The significant level was set to 0.05.Results: The estimated prevalence of SLI in the population under study was estimated to be %3.3. In addition, the estimated prevalence of SLI in boys and girls was 4.2% and 2.4%, respectively. There were no significant correlation between the estimated prevalence of SLI with sex and area (P > 0.05). Conclusions: According to the findings of this study, it is important to employ screening system to find preschool children with SLI to prevent subsequent problems.Shiraz University of Medical SciencesJournal of Rehabilitation Sciences & Research2345-61672420151201The Study of the Development of Dependent Possessive Pronouns in 2.5-4 Year-Old Typically Normal Persian-Speaking Children971014108310.30476/jrsr.2015.41083ENShoelehSharifypourUniversity of social welfare and rehabilitation sciencesTaliehZarifianUniversity of social welfare and rehabilitation sciences0000-0002-6067-829xAyoubSheikhiShahid Bahonar university of KermanSharifehSharifypourPayam Noor University of TehranJournal Article20160119Background: Pronoun error is one of the most common errors in many speech and language disorders. Therefore, knowing about the development procedure of dependent possessive pronouns (as a subgroup of pronouns), leads to build an accurate profile for evaluation and treatment of many disorders. The goal of the present study was to examine the development of dependent possessive pronouns in 2.5-4 years old Persian-speaking children.Methods: In this cross sectional descriptive-analytic study, 177 typically normal Persian speaking children in age range of 2.5-4 years old (94 girls and 83 boys) who were selected by stratified sampling method from 10 kindergartens of Kerman were examined. There were 3 age groups (2.5-3, 3-3.5 and 3.5-4 years old). The instrument used in this study was a researcher-made task consistent of 18 questions about some parts of body to examine the development of dependent possessive pronouns. For descriptive report central tendencies and indices of dispersion were used and for statistics relations Spearman’s correlation test, Mann-Whitney test, Kruskal-Wallis test and Cochran’s test were used.Results: The order of correct use of dependent possessive pronouns was from singular to plural and the order of person was 3rd person, 1st person and then 2nd person. There was a correlation between age and correct use of dependent possessive pronouns (P<0.05). The performance of girls and boys were similar (P>0.05), but children’s performance in 3 age groups were different (P<0.05) and correct use of 6 types of dependent possessive pronouns were significantly different (P<0.05).Conclusion: The correct use of dependent possessive pronouns increased with age, and by the age of 4, the children mastered in more than 90% of dependent possessive pronouns.
