Comparison of regular aerobic and yoga on the quality of life in patients with multiple sclerosis
Background: The pathophysiology of multiple sclerosis (MS) is characterized by fatigue, motor weakness, and spasticity, to name a few. MS symptoms may lead to physical inactivity associated with the development of secondary diseases. This study was to investigate the effect of regular aerobic and yoga on the quality of life of patients with MS. Methods: The present quasi-experimental study was conducted on 90 patients with chronic MS chosen randomly and divided into two test and one control groups. Data were analyzed using SPSS software (version 11.5) through paired t-test, ANOVA, and Tukey's post hoc. Results: There were no significant differences among the scores of quality of life in the three groups prior to investigation. Although they were significant after intervention. The mean score of yoga group was higher than that of aerobic group, and aerobic group showed a higher mean score compared with the control. Conclusion: Yoga and aerobic exercises may improve quality of life in patients with MS. It is highly recommended that the governor along with MS societies and other organizations servicing and supporting patients start to develop sport-regulated programs to help improve quality of life for these patients
Psychometric Evaluation of the Receptive Picture Vocabulary Test for Persian-speaking Children
Background and Objectives: Measuring children’s receptive vocabulary skills requires the use of valid and reliable tools. This study aims to assess the reliability of the receptive picture vocabulary test for Persian-speaking children (RPVT-P).
Methods: In the first phase of this cross-sectional, descriptive, and analytical study, 434 normal children aged 30 to 71 months participated. In the second phase of the study, 2 groups participated, 16 children with Down syndrome (DS) a mentally age-matched typically developing (TD) peers. The internal consistency (Cronbach’s α coefficient), construct validity, and discriminant validity of the RPVT-P was evaluated.
Results: Cronbach’s α was calculated as 0.825, indicating good internal consistency for the total score of the RPVT-P. The Spearman correlation coefficient of 0.83 showed a positive correlation between age and the total score of the RPVT-P (P=0.0000). The correlation between most of the subtest scores and the total score of the RPVT-P was found from 0.70 to 0.87, showing acceptable construct validity. A significant difference was observed between the DS and TD groups for the total scores of the RPVT-P (P=0.0000), indicating good discriminant validity of the RPVT-P.
Conclusion: The RPVT-P is a test with acceptable validity and reliability to determine the ability of preschool Persian-speaking children in receptive vocabulary
