Background and Aim: In recent studies of balance and instability, a condition has been reported as a common motor disorder in Parkinson's patients, leading to frequent falls, decreased quality of life and mortality in these patients. On the other hand, evidence has shown that exercise is effective in treating motor and cognitive symptoms of neurodegenerative patients. Method: 24 male Wistar rats were randomly divided into three groups: healthy control, Parkinson's control, and Parkinson's training. The animals in the training group were placed on a treadmill for 4 weeks. At the end of the course, motor disturbances (balance and motor behavior) were evaluated using Rotarod and Open-Field tests, and biochemical factors were assessed by ELISA method.Results: Data analysis and analysis using one-way ANOVA and Tukey's post hoc test at a significant level (p

Introduction: Menopause is beginning of a new era in a woman's life. This period, like other stages of life, has positive and negative aspects. The aim of present study was effect of Pilates exercises on BDNF serum level, balance and quality of life menopausal and non-tmenopausal women.Methods: The current study was semi-experimental with pre-test and post-test design included two experimental and two control groups. The statistical population was all menopausal and non-menopausal women of Urmia city. The sample consisted of 60 women (age 45.77±1.77) menopausal and non-menopausal who were voluntarily selected and randomly divided into four groups of 15 people. Fasting blood was taken from all subjects 48 hours before the start of training and after the end of training period. Then both experimental groups performed Pilates exercises for 12 weeks, three sessions per week and each session lasted 60 minutes. Also, the participants performed Y dynamic balance test and World Health Organization quality of life questionnaire in pre-test and post-test.Results: The results of Mixed ANOVA showed significant difference between pre-test and post-test of menopausal and non-menopausal women in relevant variables, so it can be said that probably 91%, 76% and 94% of the changes in BDNF serum level, balance and quality of life of menopausal women are influenced by Pilates exercises. While in control groups, no significant effect was observed in the relevant variables.Conclusion: Pilates exercises can be an effective strategy to improve serum BDNF level, balance and quality of life in menopausal and non-menopausal women.

Introduction: Multiple sclerosis (MS) is one of the most common chronic inflammatory autoimmune diseases of the central nervous system that affects the motor and sensory systems to control balance while standing and walking. This study aimed to investigate the effect of eight weeks of proprioceptive training on balance, fatigue, and quality of life of women with MS.Methods: The statistical population of this research included 20- to 50-year-old women with MS and a total score of 1 to 4 on the Expanded Disability Status Scale (EDSS) that are members of the Isfahan MS Association. From this population, 30 volunteers were selected conveniently and assigned to experimental and control groups. Participants of both groups completed the Fatigue Severity Scale (FSS), Multiple Sclerosis Quality of Life-54 (MSQOL-54), and Berg Balance Scale (BBS) tests before starting the training program. The experimental group performed 60-minute proprioceptive training for eight weeks and three sessions a week, and the control group performed their daily activities during this period. After 8 weeks of training, both experimental and control groups repeated the previous tests. The data were analyzed using independent and paired t-tests at the significant level of 0.05.Results: The results showed that there was a significant difference in balance, fatigue, and quality of life of the experimental group in the post-test compared with the pre-test (P<0.05). Also, the comparison of the post-test results of the two experimental and control groups showed a significant difference in the balance and quality of life of MS patients (P<0.05).Conclusion: Overall, eight weeks of proprioceptive training improved the balance and quality of life of MS patients, but it was not effective in reducing their fatigue. Therefore, the use of proprioceptive training is recommended for the well-being of MS patients.

The Effect of Sensory-Motor Integration Training With Help of Interested Parent on Balance in Autism Children AbstractThe pervasive development disorders is one of the most common cases is autism. This disorders include a group of psychological disorders in which social interaction skills and communication skills have been destroyed. With consider to high costs of treatment for autism, the use of alternative therapies suitable for autistic patients, especially children, and improving their quality of life is one of great importance. The aim of the present research is to determine the impact of course of sensory-motor integration training with help of interested parent to improve balance improvement of children suffering from autism. For this purpose, 24 autism children aged 6-10 years selected to this study and participated to sensory-motor training for 10 weeks. Participants asked to 2 stages of pre-test and post-test for balance skill. They were evaluated based on Laklak and Tandem Gait test. In order to analyze the effects of the research protocol, the analysis of variance with repeated measure and the scheffe post-hoc test was used at the significant level of P≤0.05. The results showed that sensory - motor integrity training significantly improved the static and dynamic balance skill and parent-centered approach have had higher benefits in improving dynamic balance with positive effects through manipulation of psychological features such as sense of belonging and solidarity, motivation and higher assurance.

The aim of this study was to determinate the validity and reliability of the Persian version of the Brief-BES Test in the elderly. The final version of the Brief-BES Test in the elderly was retranslated and developed based on the viewpoints of experts in elderly studies. 100 elderly men and women were voluntarily selected from Hakim Elahi nursing home in Semnan city. The data were analyzed using descriptive and inferential statistics: confirmatory factor analysis (CFA) and Cronbach’s alpha coefficient to examine factorial and construct validity and internal consistency respectively. Findings indicated good fit of the factor analysis model over the Persian version of the Brief-BES Test in the elderly. In addition, the results of Cronbach’s alpha coefficient demonstrated the acceptable internal consistency of this tool. Proper translation and selecting a heterogeneous sample may have contributed to the good fit of the factor analysis model.

The aim of this study was to investigate the effect of game-oriented exercises on motor development of overweight children with developmental coordination disorder. The research method was semi-experimental with pretest and posttest. 50 overweight children aged between 8 and 10 with developmental coordination disorder were selected and were randomly assigned to experimental (n=35) and control (n=15) groups after pretest. The experimental group participated in the protocol for 3 sessions per week during 3 months. MABC-2 test was used and SPSS 21 software was used for data analysis. The results of MANCOVA showed a difference between the experimental and control groups in at least one of the variables. Based on the results of one-way covariance analysis with a significance level of 0.05, there was a significant difference between the control and the intervention groups in motor development components and its subscales (hand speed, targeting and balance) and the experimental group got better scores. Therefore, it is recommended that the development of this disorder should be prevented in overweight individuals by designing different exercises and early intervention, and have a positive effect on their motor development.

Introduction and aims: Brain-Derived Neurotrophic Factor (BDNF) as one of the factors associated with neuromuscular performance and cognitive function is reduced with increasing age. The objective of the present study was to investigate the effects of aerobic and cognitive training on the dynamic balance, attention and serum BDNF levels in elderly men. Methods: In a quasi-experimental study, 60 healthy elderly men were selected through the purposeful sampling and were randomly divided into 4 groups including aerobic training, cognitive training, combinational training (cognitive aerobics) (cognitive training), and control. Training was performed during eight weeks at three sessions per week. T-test and one way ANOVA were used to analyze the data (P≤0.05). Results: at the end of the period, a significant increase was observed in BDNF serum in the intervention group compared to the control group (P ≥0.001). Also, there was a significant increase in the ratio of the correct response on the target and non-target stimuli. In addition, a significant decrease was observed in commission errors and omission errors, and reaction time in intervention groups compared to control groups (P<0.05). It can be added that the significant improvement was observed in dynamic balance in aerobic and combination groups compared to the control (P<0.001) and cognitive training (P<0.05). Conclusion: Cognitive and aerobic training lead to improving the attention and balance performance in the elderly with increasing BDNF, and it is better to use a combination of physical and cognitive training for the elderly.

The purpose of this study was to compare instructor-based and parent-based interventions on motor development in 7 to 10 years old children with developmental coordination disorder. Participants consisted of 84 girls and boys from 8 elementary school at 4, 8 and 13 Tehran educational zones; they were screened by developmental coordination disorder questionnaire, then randomly divided into three groups: instructor-based, parent-based, and control. Two experimental groups carried out skills training for 12 weeks consisting, 36 sessions, each session 45 minutes. All participants were assessed before and after interventions with Movement Assessment Battery for Children; Second Edition. The result of MANCOVA and ANCOVA tests showed that both experimental groups significantly in the total score of motor development (p≤0.05) and its components (manual dexterity, balance, aiming and catching) had higher score than the control group (p≤0.017), and of course Instructor-based group in the aiming and catching subscale had better performance than parent-based group (p≤0.05), that demonstrates positive impact of group environments. In summary, although both interventions help to improve motor development in children with developmental coordination disorder, instructor based intervention is more beneficial in some of the components of motor development.

Aim: One of the issues that have been considered more than before is the issue of aging. An aging is a period that is accompanied by gradual, progressive and spontaneous erosion changes in most physiological devices and functions of the body. One of the widespread problems that occur in the aging process is the loss of balance, increased fluctuations and the risk of falling. Falling down is one of the most common and most serious problems are aging. For this reason, today, many researchers have drawn attention to the various ways in which elderly people develop their balance. Recently, some researchers have found that the use of cognitive strategies such as self-talk can improve the performance of motor tasks. Self-talk, essentially has two main instructional and motivational functions. Motivational self-talk through increased self-confidence and instructional self-talk by enhancing focus on techniques improve their sports performance and learning skills. On the one hand, it is important to increase the effectiveness of the instructions in order to focus on the focus. Wolfe's researches (1998-1992), given the constrained action hypothesis in most sports skills as well as balance skills, suggest that the use of external attention in comparison with internal attention during the skill leads to better performance and learning. Several studies have been conducted on motivational and instructional self-talk about different athletic skills and different skill levels that have led to a variety of outcomes, but few studies have considered the scope of balance. So, the aim of this study was to evaluate the effect of attentional focus types as the self-talk form on static and dynamic balance in elderly women using instructional self-talk focus strategy. Methodology: The present study was a quasi-experimental study with pre-test and post-test. The experimental group included instructional self-talk with internal focus and instructional self-talk with external attention as well as a control group. The population of the study consisted of all elderly women living in the nursing home in Qazvin who 45 people (66.75 ± 5.65 years) were selected according to the inclusion criteria. Inclusion criteria included Lack of movement restrictions, non-fracture in the lower extremities in the past year and the lack of use of neurological drugs. After the pre-test they were randomly assigned to groups. The control group without self-talk, self-talk group with internal focus and self-talk group with external focus practice their balance skills during the five sessions. At the end of the fifth session, the post- test was conducted using static balance (stork) and dynamic balance (timed up and go) tests. In the stork test, the subject must stand on top of his leg, lift the other leg and stick to the knee of the leg, and simultaneously place his hands on the iliac crest of the pelvis. The time that a person could stand open with his eyes was considered as an indicator of his static balance ability. Each subject performed the test three times and the highest time was recorded. The errors that caused the test to be stopped include lifting the hands from iliac crest of the pelvis, detaching the leg from the knee of the foot and any movement on the foot of the reliance.Each subject performed a three-time test of timed up and go, and his best time was recorded. Since the subject was announcing his stand, the timer began to work, and the timer stopped when it hit the subject back with chair. The self-talk group with the instruction of focus of the internal attention, repeated the words "knee and foot" before each loud performance, which meant "bending slightly knees and maintaining the balance on the foot", and the external attention group referred to the term "target and wall" Which meant "looking at the target mounted on the wall.Results: One-way ANOVA, mixed ANOVA and repeated measure ANOVA were used to analyze the data. Data was analyzed using SPSS software version 20. The significance level was considered 0.05. The results showed that both self-talk groups performed significantly better than the control group in static balance.Conclusion: However Self-talk interferences with both types of attentional focus; it was not a significant difference in the dynamic balance of elderly people (P≥0.05). Taking the results into consideration it can be concluded that, self-talk with internal and external focus instructions can be considered as a cognitive strategy to improve the static balance of elderly people.

The aim of this study was to investigate the effect of selected spark exercises on balance and coordination in autistic children. This study was semi-experimental. 12 autistic children (mean age 5-12 years) participated in this study. The subjects performed the intervention for 3 months based on selected spark exercises. The participants were evaluated in 3 stages (baseline, pretest and posttest) by Bruininks-Oseretsky test in terms of motor skills. Friedman test was used to analyze repeated measures of nonparametric data. The results showed that selected spark exercises significantly improved dynamic balance (P<0.001) and bilateral coordination (P<0.001). It can be generally stated that these selected spark exercises have a positive effect on the improvement of motor deficiencies in autistic children.

The aim of the present study was to investigate the effect of contextual interference on balance of mentally retarded people. For this purpose, 40 educable and mentally retarded boys in Qazvin city (mean age 24.45 ± 3.120) were randomly divided into two groups: blocked and random practice. After the pretest, given their practice arrangement, subjects in each group performed their workout for 4 weeks (3 sessions per week) as the acquisition phase. Acquisition test was conducted in the last session, and then retention and transfer tests were performed after 48 hours. After Kolmogorov-Smirnov test verified normal data distribution and Leven test examined the homogeneity of variances, analysis of variance with repeated measures showed that the intervention was effective and the groups significantly improved (P=0.0005). The results of the independent t test (to compare two groups in static balance) showed that random practice group performed better in retention test (P=0.007) whereas no significant differences were observed between the groups in transfer test (P=0.061). In addition, dynamic balance results showed that random practice group performed better than the blocked practice group and it had a significant difference in retention and transfer tests (respectively P=0.001, P=0.002). So, mentally retarded people can use the beneficial effects of random practice.

The aim of the present study was to examine the reliability and validity ofbalance performance clinical tests for hearing impaired persons with moderatehearing level. In this descriptive-survey study with repeated measures, 220 hearingimpaired subjects with normal intelligence and moderate hearing level wereselected as the statistical sample from all deaf and hearing impaired subjects whohad participated in national competitions in Arak city. The scale (3) of CattellCulture Fair Intelligence Test and motor performance clinical tests were used tocollect the data. After checking the date normality, data were analyzed with intraclassand interclass correlation coefficients and factor analysis tests. The resultsrevealed that finger-to-noise test with dominant hand (ICC=0.79), and with nondominanthand (ICC=0.81), time-up and go test (ICC=0.76), and tandem gait test(ICC=0.87) were reliable. But, the dominant and non-dominant single leg stancetests with open and closed eyes were not reliable (ICC<0.75). The validity ofbalance performance clinical tests was confirmed with factor analysis test. Overall,the finger-to-noise with dominant and non-dominant hand, the time-up and go, andthe tandem gait tests were the most stable tests to assess balance and coordinationof hearing impaired participants.

Attention is one of the effective factors when learning and performing motor skills. Focus of attention is a method to increase the efficiency and learning. Previous studies have shown that focus of attention plays an important role in learning and performing motor skills. The purpose of the present study was to compare the effect of the instruction of far and near external focus of attention on dynamic balance task performance. In this study, sixty male undergraduate students of Ferdowsi University of Mashhad, who had taken the general physical education course in the second semester of 1388-89, were assigned randomly in three groups: far external attention group (attention to those signs far from the feet), near external attention group (attention to those signs near the feet) and control group (no attentional instruction). The stabilometer (Biodex) was used to collect the data. Each participant performed three 20-second trials in dynamic balance test. The obtained data were analyzed by descriptive statistics as well as inferential statistics such as one-way ANOVA and Duncan post hoc test. The results showed that far external attention group performed significantly better than control group while near external attention group did not reveal any significant difference compared to the control group.
