Background: Visual impairments affect all motion aspects of individuals. Movement as the most important tool of physical education is an important factor to improve the health of people with disabilities. The present study aims to investigate the effect of six weeks of core stability training on postural control, risk of falling, and function of blind people. Material and methods: Thirty-two blind males were randomly divided into two groups: the experimental and the control one. In order to evaluate the postural control, the Berg balance scale, the modified stork stand balance test, and the tandem walking test were used. To evaluate the risk of falling and function, the Timed Get up & Go and Tinetti tests were employed, respectively. Data were analysed via MANOVA statistical analysis test at the significance level of 0.05. Results: Results showed that, after 6 weeks of core stability training, a significant increase was observed in postural control scores, function, and risk of falling in the experimental group compared to the control group and the pre-test condition (P < 0.05). Conclusions: Considering the importance of mobility, especially in people with visual disabilities, the use of core stability training

Objective: The present study aimed to investigate the flexibility of the ankle and knee joints and to determine its relationship with balance, motor function, and risk of falling in visually impaired individuals. Methods: The sample consisted of 32 blind males, 20-30 years old. They were selected by the purposeful sampling method. We used modified stork tests, tendon gait, and Berg balance scale to evaluate their balance. The Tinetti test was used to evaluate motor performance and the Timed Up and Go (TUG) test to assess the risk of falling. The SLR test and Lunge test were used to assess the range of motion of the knee and ankle joint, respectively. This study was conducted in the men’s dormitories of Tehran University in the fall of 2019. The obtained data were normalized using the Shapiro-Wilk test and Pearson correlation coefficient at the significant level of 0.05 to investigate the relationship between the variables. Results: The results of the Pearson correlation test showed a significant relationship between balance (P=0.001), motor function (P=0.002), and TUG fall risk test (P=0.010) (ankle motor restriction). On the other hand, there was a significant relationship between balance (P=0.002), motor function (P=0.001), and TUG fall risk test (P=0.003) with hamstring flexibility test (knee motor restriction). Conclusion: Given the significant relationship between the range of motion of the lower limbs with balance and motor function, the use of stretching exercises can be an influential factor in increasing the range of motion of the ankle and knee in blind people, which improves balance, motor function, and reduced risk of falling in blindness.

Background and Aim:Weakness in the sensory-deep receptors of the sole of the foot is one of the important factors in lower limb movement disorders and balance in the blindness. Therefore, the aim of this study was to compare the effect and durability of foot massage techniques on the balance of the blindness Methods:The present study was a one-way blind with a pretest-posttest design. The statistical sample consisted of 30 blind boys aged 20-30 years who were randomly divided into three groups of 10 people. The protocol of massage methods was performed on the samples for 21 days. Biodex balance system was used to evaluate the balance. The normality of the data was analyzed using Shapirowilk test and the analysis of variance with repeated measures was used to analyze the differences within the group and the ANOVA test was used to examine the differences between the groups at the significance level of 0.05. Results:The results of intra-group test showed that all three methods of foot massage improved static and dynamic balance in the blind (P <0.001). The results of ANOVA test for comparison between groups showed that there is no significant difference between the three methods of foot massage on static balance and posterior anterior index of dynamic surface and internal-external index of dynamic surface (P> 0.05) and only on the general surface index. There is a significant difference in the dynamics of hand massage compared to the other two massages (P <0.001). Conclusion:Due to the significant effect of foot massage methods on the balance of the blind, foot massage can be used as an effective factor in strengthening the sensory receptors of the foot and ultimately improving the balance of the blind.

Introduction: The present study aimed to investigate the effects of 6 weeks of Dynamic Neuromuscular Stability (DNS) training on performance (lower limb strength, flexibility, fall risk) and quality of life in the elderly. Materials and Methods: This was a quasi-experimental study with a pretest-posttest design. This research was performed on 30 elderly males, aged 60-70 years in Qom Province, Iran in 2021. The examined elderly were randomly divided into the experimental and control groups (n=15/group). Furthermore, the experimental group participated in three 45-minute weekly sessions of DNS training for 6 weeks. To collect the necessary information before and after applying the training protocol, tint tests, 30-second seat sitting test, sitting and delivery test, TUG test, and SF-36 questionnaire were used. The obtained data were analyzed using Analysis of Covariance (ANCOVA) and Paired Samples t-test at a significance level of 0.05. Results: The ANCOVA results indicated a significant difference between the experimental and control groups in motor function, fall risk, quality of life, lower limb strength, and flexibility (P<0.05). The collected mean scores outlined that the experimental group performed better than the control group. Conclusion: Due to the effectiveness of DNS training on physical function and the very high importance of the elderly lifestyle, it is recommended that the provided training protocol be used for prevention and rehabilitation, increase the level of physical fitness and quality of life as a low-cost treatment, among the elderly.

Background: The aim of this study was to compare the psychological parameters in Coper individuals and people with chronic ankle instability (CAI).Methods: This study was a cross-sectional and comparative study. Sixty elite athletes, from multiple athletic disciplines, who have suffered from lateral ankle sprains at least once in the last two years, were selected as research subjects and were divided into two groups: Copers (n = 30) and CAI (n = 30). Classification of CAI, and coper groups were done by AJFAT, CAIT and FAAM self-report questionnaires. Athletes' psychological characteristics were measured using the Ottawa Mental Skills Assessment Tool (OMSAT-3). Multivariate analysis of variance (MANOVA) and independent t-test were used to evaluate the differences between groups at a significance level of 0.05. Results: The results showed there was a significant difference between the two groups in Goal setting, Self-confidence, Commitment, Relaxation, Fear control and Coping with stress, Focusing, Refocusing, and Mental practice (P <0.05). And Coper athletes scored higher than ankle instability athletes. But there were no significant differences between the two groups in the following parameters: Inactivation, Imagery, and Competition planning skills (P <0.05).Conclusion: The findings showed that athletes with CAI scored lower than Coper athletes on psychological exams. Given the importance of prioritizing the mental components of goal setting, imagery, relaxation, activation, and self-confidence, the design of the competition should be a priority for rehabilitation. Therefore, coaches and sports experts are recommended to focus and improve mental skills in athletes who suffer from sports injuries, to reduce the occurrence of repetitive sports injuries.
