Several factors such as age, task complexity, and bilingualism affect executive functions. There are opposing effects for the role of bilingualism on executive functions. This study aimed to compare executive functions of bilingual patients with Relapsing-Remitting Multiple Sclerosis (RRMS) with their monolingual counterparts. <br><strong>Materials and Methods:</strong> In this cross-sectional study, 13 bilingual patients with RRMS are compared with 13 monolingual peers. The research instrument included progressive matrices raven test, Mini-Mental State Examination (MMSE) and clinical tests of executive functions (continuous performance test, Wechsler memory test and verbal fluency test). The Mann-Whitney test was used as statistical analysis.<br><strong>Results:</strong> The results indicated statistically significant differences between two groups with regard to correct response, error of omission, and commission error. However, there was no difference in the digit span test. Monolinguals in Persian language, however, performed better than bilinguals in all verbal fluency tasks.<br><strong>Conclusion:</strong> Bilingualism promotes cognitive ability and executive functions in nonverbal tasks. Ironically, it seems that the only recorded negative impact of bilingualism are on verbal knowledge and skill.</p> 2019-01-09T12:58:32+0330 ##submission.copyrightStatement## Structured Pattern for Prediction of Parental Stress Based on Self-Differentiation of Parents With Mediating Role of Family Performance With Autistic Child 2019-01-12T16:44:10+0330 JMR Office Monir Kalantar Ghoreishi Hassan Asadzadeh Khadijeh Abolmaalial Hosseini <p><strong>Introduction:</strong> According to studies, raising a normal child is already a difficult task for parents. Now, imagine how hard it could be to raise an autistic child. Based on family stress theory, persona, and family resources are considered as main elements which may have effects on the relationship between having an autistic child and positive/negative parenting consequences. The present study aimed to evaluate parental stress modeling based on parents’ differentiation of self and mediating role of family performance with their autistic child. This was a correlational study based on structural equations modeling. <br><strong>Materials and Methods:</strong> Statistical population consisted all mothers of autistic children who were studying in the autistic schools in Tehran. In this research, 250 mothers with autistic children were selected by convenience sampling method based on Lohlin method for sample size (2004). Then they were evaluated by multidimensional scale of differentiation of self inventory-revised, family assessment device, and parental stress index-short form. The obtained data were analyzed in SPSS 24 and AMOS 23.<br><strong>Results:</strong> Based on the findings, three variables could predict parental stress (R2=0.51) and 51% of parental stress are explained by parents’ differentiation of self as well as family performance. Also, the indirect way of parents’ differentiation of self with mediating role of family performance on parental stress was supported. <br><strong>Conclusion:</strong> Focusing on self-differentiation as well as family performance and emphasizing on parental stress of mothers with autistic children and training coping strategies may have significant effects on decreasing the stress and vulnerability of these parents.</p> 2019-01-09T12:53:53+0330 ##submission.copyrightStatement## The Relationship Between Auditory Perceptual Evaluation and Acoustic Measurements of the Voice in Dysphonia: Some Issues About the Task Effect on Perceptual Rating 2019-01-09T13:14:02+0330 JMR Office Seyyedeh Maryam Khoddami Nazila Salary Majd <p><strong>Introduction:</strong> This study aimed to investigate construct convergent validity of the Persian version of consensus auditory perceptual evaluation of voice (called ATSHA), using the acoustic measurements. Moreover, the effect of voice tasks on the perceptual ratings was studied.<br><strong>Materials and Methods:</strong> The study data were gathered from a total of 40 dysphonic patients (Mean±SD age=36.79±8.26 years). Perceptual voice evaluation was performed using the ATSHA during sustained vowels and sentence reading tasks. The acoustic features including fundamental frequency (F0), intensity, jitter, shimmer, and Harmonics-to-Noise Ratio (HNR) were extracted using Praat application. To assess construct validity of ATSHA, correlation between perceptual and acoustic measures were studied. The effect of tasks was investigated by mean comparison and Pearson correlation.<br><strong>Results:</strong> The results demonstrate that ATSHA has significant correlation with all acoustic measures except the frequency (r=-0.08-0.35; P≥0.05). There was no significant correlation between pitch and the acoustic measures of intensity and jitter (r=-0.31; P=0.05 and r=0.24; P=0.14, respectively). The highest correlation observed between the overall severity and the HNR (r=-0.85; P&lt;0.001). The correlation between the perceptual scores in both tasks was high (r=0.82-0.99, P&lt;0.05).<br><strong>Conclusion:</strong> The ATSHA is a valid scale for perceptual judgment on intensity, jitter, shimmer, and HNR. However, this scale could not estimate the frequency of voice in dysphonia. The current study demonstrate that vowel prolongation and sentence reading has no noticeable effect on the perceptual ratings in dysphonia.</p> 2019-01-09T12:42:36+0330 ##submission.copyrightStatement## Effects of Peroneal Muscle Fatigue on Ground Reaction Force Profile During Lateral Hop Landing 2019-01-12T16:42:13+0330 JMR Office Kazem Malmir Gholam Reza Olyaei Saeed Talebian Ali Ashraf Jamshidi Shiva Mousavi <p><strong>Introduction:</strong> Ankle sprain occurs often late in sport competitions consisting of many lateral ankle movements, jumping or landing, where peroneal muscles are fatigued. Changes in Ground Reaction Force (GRF) parameters may also be related to this injury. The present study aimed to assess the effects of peroneal muscles fatigue on GRF profile during lateral hop landing. <br><strong>Materials and Methods:</strong> Twenty-five recreationally active healthy males performed a lateral hop on a force plate before and after a fatigue intervention by a Biodex dynamometer using an isometric eversion at 40% of maximal voluntary isometric contraction until eversion torque decreased to 50% of its initial value. A force plate and an EMG system were used to collect data during lateral hop landing.<br><strong>Results:</strong> Fatigue was confirmed by a significant fall in median frequency (P&lt;0.05). Mean of the normalized peak GRF in the vertical direction, mean of the normalized impulse of the GRF in the vertical direction, and means of the time to peak GRF in the vertical and mediolateral directions decreased significantly after fatigue (P&lt;0.05). <br><strong>Conclusion:</strong> If the peroneal muscles are fatigued, a much more load may transfer to the vertical direction during landing, although the vulnerable part of the ankle is situated on the mediolateral direction.</p> 2019-01-09T12:27:58+0330 ##submission.copyrightStatement## Comparing Participation of Iranian Children With Cerebral Palsy in Life Activities With Participation of Typically Developing Children 2019-01-09T13:14:02+0330 JMR Office Marzieh Pashmdarfard Malek Amini <p><strong>Introduction:</strong> Children with Cerebral Palsy (CP) like the normal peers have the right to participate in life activities, so we aimed to study and compare the participation of Iranian 6-12 years old children with CP with the participation of their normally developing peers. <br><strong>Materials and Methods:</strong> This was a cross-sectional study in which the parents of 274 children with CP and the parents of 274 of normal children completed the Children Participation Assessment Scale Parent- version. For data analysis, the Independent t test was performed in SPSS version 21. <br><strong>Results:</strong> The mean age of children with CP and normal children were respectively 9.64 and 9.45 years. The results indicate a significant difference between the two groups in life activities participations (P&lt;0.05). <br><strong>Conclusion:</strong> Participation of Iranian children with CP in life activities (activities of daily living, instrumental activities of daily living, play, leisure, social participation, education, and sleep/rest) are lower than those normal peers, so the occupational therapists should pay attention to this and try to promote the participation of children with CP.</p> 2019-01-09T12:17:48+0330 ##submission.copyrightStatement##
