Purpose: The aim of this study was to compare the effect of eight weeks physical and mental rotation training on the balance and falling of elderly women. Method: The present study is a quasi-experimental study with a pre-test, post-test and two-way ANOVA, which is also t-test designed. Tools included: mental rotation questionnaire and functional reach test. The participants included: 36 patients (12 subjects in three groups of physical training, mental rotation and control group) have been randomly selected among the elderly women of an elderly Centre in Tabriz. The training program was administered in two groups of physical training and mental rotation for eight weeks, at three sessions in a week and a group of control with no intervention.  For data analysis, the SPSS software, version 21 was used. Results: One-way ANOVA showed, the mean balance among the elderly women was significantly different from the physical training group. The relationship between post-test mental rotation and pre-test physical training was significant at the 0.01 level. Also, the relationship between the post-test mental rotation group and the pre-test mental rotation group was significant at the level of 0.05 and the relationship between mental rotation and balance among elderly women is significant at the 0.01 level, at the end the relationship between mental rotations and falling in the elderly was significant at 0.05 level. Conclusions: The results of this research indicates that the physical training and mental rotation training had a positive effect on the balance of the elderly women and it also showed that the elderly women of the physical training group had more improvement on balance than mental rotation groups. So, this research indicates that, cognitive abilities and movements could be facilitating and effective in this way.

This paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. The purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. Consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectonics and neotectonics …) to the basin based cybernetics (including geomorphic, topographic and geological state) and also to calculate energy and material balance considering positive and negative entropy at basin level. Based on the findings, which is the outcome of cybernetic resultant between form and process in basin, we can determine stability and type of balance in the basin. In this paper, emphasis has been put only on rainfall (express of the energy exponent). However, it first discusses Kor Basin Geomorphic locations and Energy-Material Entropy on its surface and then Quantity form of energy (Isolated & Potential Energy). Considering geomorphic state of the basin, we can determine the best planning method from all systems (planning, risk management and crisis management) for basin that neither requires a great cost nor causes disturbance in stability and geomorphic balance while being the optimal process. In Kor geo planning, we are encountering and determining two dimentions: (Y dimension, for geomorphic change for example throughput topogeraphy geradient formations on Kor Basin and X dimension, for rainfall discharge range on Kor Basin rivers out let only and only on fiat paper surface), but in Kor geo management, we represent at least three – dimensional ordered, for example topogeraphy gradient for Y coordinate and rivers discharge quantity for X coordinate and absolution geography location (for space point Z coordinate). Consequently, Kor River Basin can be studied based on two scientific metod : I . Planning & II , Management .

This research investigated the effect of insomnia caused by military guarding on motor performance and salivary cortisol and testosterone concentration. Some 24 male active-duty soldiers were randomly selected and placed in two groups, insomnia, and control. Insomnia consisted of two hours of guarding with military equipment, two hours of on-call, and two hours of sleep, which started at 4:00 PM and lasted until 6:00 AM the next day. Agility, balance, and reaction time were measured as indicators of motor performance. Saliva samples were collected in the morning two days before, in the morning after applying insomnia, and after measuring motor performance. The results showed that agility performance in the insomnia group was weaker than in the control group. The balance performance of the insomnia group did not differ significantly from the control group. The reaction time in the experimental group was slower when compared to the control group. Although the reaction time was affected significantly, the findings of this research showed that salivary cortisol and testosterone concentration, as well as agility and balance, are not affected by this amount/type of sleep deprivation.

Background: Diabetic peripheral neuropathy (DPN) reduces the senses, proprioception, reflexes, and strength in the lower extremities and leads to balance dysfunction. Aim : This study aimed to evaluate the effectiveness of interventions used by researchers and therapists to minimize balance dysfunction in people with DPN. Materials and Methods: This study is a comprehensive review of exercise interventions on the balance of patients with diabetic neuropathy by searching in the PubMed Elsevier, Springer, Science Direct, Google Scholar, and Scopus databases with the combined keywords “balance”, “diabetic peripheral neuropathy”, “training interventions”, “proprioception”, “risk of diabetic fall”, “peripheral neuropathy” and also in Persian databases of Jihad Daneshgahi Scientific Information Center, MedLib (Comprehensive Database of Medical Articles), IranMedex, Iran Institute of Information Science and Technology Research Institute (IRANDOC), Iranian Publications Database (MAGIRAN) and with keywords “fall risk”, “profundity” and “postural control in diabetic neuropathic patients” from 2010 to 2021. After collecting the search results, first the title and then the summary of the pieces were studied. If the articles met the inclusion and exclusion criteria, their results would be used in the review study and otherwise discarded. Results: Twenty-five studies published between 2010 and 2021 met the inclusion criteria. The results showed that training interventions were more effective than control conditions to improve the balance of patients with diabetic neuropathy. Also, the most training programs and rehabilitation protocols have a positive effect on the balance of patients with diabetic neuropathy. Conclusion: The studied exercise interventions are an effective tool to improve the balance of diabetic neuropathy patients. However, given the small number of studies and their limitations, the present findings of this study should be considered.

Purpose: This study was conducted aiming to investigate the effect of selected TRX and Pilates training on balance parameters, fatigue index, and quality of life in female patients of multiple sclerosis. Method: In this study, 30 female patients with MS in Isfahan city with an average age of 37.41 ± 7.57 years and a history of MS of 11.31 ± 3.77 years and an Expanded Disability Status Scale of 0.84 ± 1.81 were placed in three groups including control, TRX and Pilates groups. The training program consisted of eight weeks including 3 sessions of 60 minutes of exercise per week. In order to investigate balance, fatigue, and quality of life, the Berg test, Fatigue Severity Scale, and Multiple Sclerosis Quality of Life were used respectively. SPSS version 25 software was used for statistical analysis. Results: The results of this study have shown that both exercise programs have led to a significant improvement in the mean parameters of balance (P < 0.005), fatigue (P < 0.005), and quality of life (P < 0.001). Conclusions: Considering the noticeable impact of these training protocols on the quality of life, balance and fatigue, these interventions can be considered as an efficient and cost-effective methods to improve health condition in MS patients.

Motor learning studies on adults have shown that directing the learners’ attention to external cues is more effectual than internal cues. In this study, we investigated if this could be applied to children with developmental coordination disorder (DCD). 45 boys with developmental coordination disorder were selected using motor observation questionnaire for teachers. The task was static balance test that was measured in two experimental conditions including internal (focus on body limb) and external (focus on rex marker) focus of attention. For data analysis, ANOVA and Tukey’s post hoc were used at the significant level of P < 0.05. Results showed that external focus could improve motor learning. However, there was no significant difference between internal focus and control groups. Thus children with DCD benefit from the external focus of attention to learning a static balance skill. According to the results of this study, therapists and coaches should adjust their rehabilitation methods and instructions based on external focus of attention.

Background: The SARS-CoV-2 virus is viewed as one of the defining crises of the current era, with various adverse ramifications for sports performance. Aim: The objective of the present study was to investigate the effect of aerobic exercise and caffeine supplementation on the cognitive performance and balance of college student-athletes recovered from COVID-19. Materials and Methods: Forty male student-athletes aged between 18 to 25 years from the Imam Khomeini International University of Qazvin were randomly assigned to four groups: 1. exercise + caffeine supplementation, 2. aerobic exercise + placebo, 3. aerobic exercise, and 4. control, in a pre-test post-test design. The Shapiro-Wilk test was used to check the normality of data distribution and covariance analysis was used for inter-group comparison. Results : The ANCOVA analysis showed significant differences in cognitive performance and balance among the four groups ( P <0.05). Pairwise comparisons using the Bonferroni post-hoc test showed statistically significant differences in cognitive performance and balance between the aerobic exercise + caffeine group versus the aerobic exercise + placebo group (P<0.05) and the aerobic exercise versus the control group ( P <0.05). Also, there was significant differences in mean cognitive performance and balance indices between AE+CAF versus CONT ( P <0.005) and AE+CAF versus AE ( P <0.005). Conclusion: The results of this study show that aerobic exercise with caffeine supplementation can improve cognitive performance and balance of student-athletes recovered from COVID-19.

Background: Both of transcranial direct current electrical stimulation (tDCS) and neuromuscular training (NMT) have used to relive motor deficits in neurological disease.Aim: We decided to investigate augmenting effect of tDCS and NMT to improve static and dynamic balance and gait parameter in autism spectrum disorder (ASD).Materials and Methods: 24 children with ASD aged 6-10 years old were randomly assigned to one of three groups: NMT+ sham, anodal tDCS, and NMT + tDCS. NMT consisted of 10 sessions motor training (each for 40 min). tDCS training was performed with 1.5 mA on left primary motor cortex for 20 min. Pre-test and post-test evaluations included static and dynamic balance and gait parameters (length and width of stepping and speed of gait).Results: Although improvement of variables were seen in all groups, but in post intervention comparison, combined group was better in static and dynamic balance and gait parameters than two other groups. NMT was more effective than tDCS only in dynamic balance.Conclusion: Our findings were indicated tDCS enhance NMT effect on neuromuscular function in ASD, so regarding the augmented effect in combination of NMT and tDCS, it can be considered in rehabilitation of motor deficits in these children.

Background: Losing a limb can negatively impact balance and gait, leading to reduced quality of life.Aim: This study aimed to examine correlations between spatiotemporal gait and balance with scores of the Quality of Life questionnaire.Materials and Methods: 30 veterans with unilateral below-knee amputations underwent gait analysis to measure step length, stride length, stance time, cadence, velocity, and walking symmetry index by step length. Static balance was assessed via the center of pressure path length by Wii Balance Board during standing. The Timed Up and Go test evaluated dynamic balance. The QoL scores were recorded using the Quality of Life questionnaire for amputees, Trinity Amputation, and Prosthesis Experience Scales (TAPES). Pearson’s correlation coefficients were calculated between spatiotemporal of gait, balance scores, and TAPES domain outcomes.Results: Stride length (r=0.660), prosthetic step length (r=0.648) and intact step length (r=0.618) showed significant moderate positive correlations with psychosocial adjustment, while amputation limb stance time (r=-0.409) correlated weakly. Activity limitations negatively correlated with step/stride lengths (r range -0.781 to -0.784) and cadence (r=-0.538). Moreover, prosthesis satisfaction was associated with improved walking symmetry (r=0.445) and prosthetic stance time (r=0.388).Conclusion: Optimizing gait and balance in below-knee amputation can improve quality of life. Biomechanical factors should be targeted in rehab programs to enhance well-being.

The present study investigated the effect of eight weeks of training with a gyroscope on identifying the body position in space, the semi-dynamic balance on the ground, and Huber's device score. Two groups of 30 Air Force (IRIAF) pilots with an average age of 27 years, height of 178, and weight of 80 kg were randomly assigned to two training and control groups. The training group was exposed to eight weeks of training with the gyroscope device. The pre-test and post-test of the two groups were compared using videography, star test, and Huber's score using the statistical method of repeated measurement. In the gyro test, there was no significant difference in the detection angle of the body position in the air in any groups before and after the test. However, an increase in rotation speed was observed in the training group. In Huber's test, there was no significant change in the control group before and after. However, in the training group, an improvement in the score was observed, especially in the non-superior limb, as well as a decrease in the difference in the score between the two hands. Stars were not observed in any groups before or after the test. According to the results, it can be concluded that despite the non-significance of the difference in the subjects' ejection angle and position identification in the training group, it occurred simultaneously as the rotation speed increased
