Introduction: Although transcranial direct current stimulation (tDCS) of the cerebellum appears to be an effective method for improving balance in elderly individuals compared to other brain regions, no comparative studies have been conducted on the effects of tDCS on the cerebellum versus the dorsolateral prefrontal cortex (dlPFC) on static balance in elderly men. The present study aimed to compare the effects of tDCS on the cerebellum and dlPFC on static balance in elderly men.
Methods: This semi-experimental study employed a pre-test-post-test design with 60 healthy elderly men aged 60 to 80 who volunteered to participate. Participants were randomly assigned to four groups of 15 individuals each: tDCS of the cerebellum, tDCS of the left dlPFC, sham tDCS of the cerebellum, and sham tDCS of the dlPFC. Static balance was assessed pre- and post-intervention using a force plate over three 30-second attempts. The intervention lasted two weeks, consisting of five consecutive sessions per week, each session lasting 20 minutes. Data were analyzed using univariate covariance analysis.
Results: The findings indicated that both tDCS of the cerebellum and dlPFC significantly improved static balance (anterior-posterior and central-lateral displacement of the center of pressure) in elderly men (P<0.05). However, there was no significant difference between the effects of tDCS on the cerebellum and dlPFC regarding static balance in elderly men (P>0.05).
Conclusion: Based on the results of the study, it is recommended that trainers and geriatric specialists utilize the benefits of tDCS on the cerebellum and dlPFC to improve static balance in elderly men.

Variation in the reception of information from depth receptors and environmental information can affect an individual's control performance. The aim of the present study was to compare the effect of walking exercises with variable speeds at different surfaces as the task and environmental constraints on balance and fear of falling. The present study was semi-experimental and was conducted as a pre-posttest with the control group. A total of 21 elderly women over 60 years old in Semnan were selected through purposive sampling and after completing the Berg Balance Test and the Short Fall Efficacy Scale questionnaire, they were randomly assigned to three groups. The fixed-constraint practice group performed walking exercises at a constant speed on a flat and smooth surface, while the variable-constraint exercise group performed balance and strength exercises with variable speed on an uneven and slippery surface. The results showed that participants' progress due to the effect of the exercises and both balance and fear of falling variables was significant. The results confirmed the different effects of variable strength and balance walking and variable speed exercises on balance; however, no statistically significant difference was observed between the three groups in the variable of fear of falling. Based on the results, walking practice at variable speeds along with manipulation of environmental constraints, can be much more useful for improving balance. Accordingly, it is suggested that this type of exercise can be considered as part of daily activity interventions and even therapy and rehabilitation in centers working with the elderly.

Introduction: Therefore, the aim of the present study was to examine the effect of a course of targeted exercises based on a difficulty index on the balance of the elderly.
Methods: In this semi-experimental study, which was conducted with a pre-test-post-test design with a control group, 75 elderly women in Mashhad, aged 65 to 75 years, were selected through voluntary participation and placed in five groups: standard-target distance, standard-variable distance, standard-target distance, variable-target distance, variable-target distance, and control. In the pre-test phase, participants stood on the Biodex balance board. The intervention phase was conducted for six weeks, with three sessions per week, in which participants performed 10 blocks of 10 attempts with two minutes of rest between blocks according to the available instructions. After completing the training phase, the post-test phase was conducted in which participants stood on the Biodex balance board as in the pre-test phase. The data were analyzed using univariate analysis of covariance.
Results: The results indicated that the standard-target-standard distance, standard-target-variable distance, variable-target-standard distance, and variable-target-variable distance interventions had a significant effect on improving the balance of elderly women (P<0.05). Other results also indicated the superiority of the standard-target-standard distance effect compared to the effect of other interventions in improving the balance of elderly women (P>0.05).
Conclusion: According to the results of the present study, it was determined that equilibrium would be facilitated by keeping the difficulty index constant, as this occurred in the test results of the group with the same difficulty index.

Introduction: The aim of this study was to investigate the effect of eight weeks of gait training with Somatosensory rhythmic stimulation on the muscle activity of the lower limbs of the elderly.
Methods: In this semi-experimental study, 29 elderly individuals (mean age: 71.68 ± 4.35; mean weight: 69.2 ± 5.74; mean height: 166.2 ± 6.52) were selected using available and targeted sampling. They were randomly assigned to two groups: an experimental group (16 individuals receiving walking training with Somatosensory rhythmic stimulation) and a control group (13 individuals without any training).The training sessions were conducted for 8 weeks, with 3 sessions per week lasting 30 minutes each.Muscle activity data was collected using electromyography in pre-test and post-test stages.The results were analyzed using SPSS software and covariance statistical method at a significance level of 0.05.
Findings: The activity of the vastus lateralis muscle significantly decreased during the loading response and swing phase (P<0.05). Additionally, the Tibialis anterior muscles showed a significant increase in the loading response phase and mid-stance, while the Gastrocnemius muscle showed increased activity in the propulsive phase following training with Somatosensory rhythmic stimulation to enhance walking performance (P<0.05).
Conclusion:The increased activity of the Gastrocnemius muscle likely contributes to improving ankle and knee joint dynamics. Moreover, the enhanced activity of the Tibialis anterior muscle in the first half of the stance phase suggests improved ankle stability and reduced knee loading by decreasing vastus lateralis muscle activity.Therefore, Somatosensory rhythmic stimulation exercises can be considered an effective method for enhancing elderly gait.

Introduction: Falling is one of the serious issues of old age that occurs due to many factors. This research aimed to compare static and dynamic balance, walking speed, spinal curvature, and central stability of elderly people with and without a history of falling.Methods: The current research was a causal-comparative research. 60 elderly women aged between 60 and 70 from Tabriz voluntarily participated in the research. The participants were assigned into two groups with and without a history of falling. The fall history of the participants was measured by the Fall Efficacy Scale. The static and dynamic balance were evaluated by Sharpened-Romberg and Timed Up and Go tests, respectively. Walking speed was measured with a 10-meter walk test, core stability was measured with McGill endurance tests, and spinal curvature was measured with a flexible ruler. Independent t-test was used to compare the mean variables in two groups.Results: The results showed a significant difference between the static and dynamic balance indices, lumbar spine curvature, walking speed, and core stability in the elderly with and without a history of falling. However, there was no significant difference between the curvature index of the lumbar spine in the elderly with and without a history of falling.Conclusion: According to the research results, it seems necessary to develop and improve the indices of balance, walking speed, and core stability in people with a history of falling.

Introduction: Task and environment constraints are very important in cognitive, perceptual, decision-making, and tactical behaviors. Task constraints are more specific than environmental constraints in performance context, therefore, the present research intended to examine the effect of manipulation of task constraints on functional indicators and the anxiety related to the fear of falling in the elderly.Methods: For this purpose, 45 elderly women (in the age range of 60 to 66 years) were randomly divided into three groups of manipulation of task constraints, without manipulation of task constraints, and control group. Then, the experimental groups performed exercises with manipulation of task constraints and exercises without manipulation of task constraints for eight weeks and three sessions per week for 45 minutes. The control group also continued their normal activities during the research period.Results: In this research, TUG and BESS tests were used to evaluate performance indicators, and Hamilton's anxiety evaluation scale was used to evaluate the anxiety index. The results of the analysis of covariance by removing the effect of the pre-test showed that in terms of performance and anxiety the group with the manipulation of the task constraints obtained significantly better results (P=0.001) than the group without manipulation and control group.Conclusion: The results of this research supported the use of various manipulations of task constraints as a kind of teaching strategy for the elderly. It also confirms the effect of exercises by manipulating the task constraints, which improves balance and reduces the fear of falling in the elderly. By improving this ability, the risk of falling in this social class is reduced.

In most people getting old is associated with a decrease in both cognitive and motor functions. One of these functions that get affected is reaction time. The aim of this study was to investigate the effect of neurofeedback training protocol variation on the reaction time of elderly people, Which is based on the principle of specificity of training. For this purpose ,Forty elderly participants between the ages of 65 to 70 years were selected and assigned to one of the for groups of experimental groups: 1) neurofeedback at Cz and beta wave, fixed frequency, fixed training arrangement, 2) neurofeedback at Cz and beta wave, fixed frequency, variable training arrangement 3) Neurofeedback at Cz and beta wave, variable frequency, fixed training arrangement, 4) Neurofeedback at Cz and beta wave, variable frequency, variable training arrangement) and 5) control (sham). All groups participated in simple reaction time tests for pre-test and post-test. The analysis of covariance showed that neurofeedback interventions had a significant effect on the reaction time of elderly people (p <0.05) and the frequency and the group with variable training arrangement had the best performance compared to the other groups (p <0.05). According to these results neurofeedback, training affects improving the reaction time of the elderly people and these interventions should be designed based on the principle of specificity of training.

The purpose of this study was to investigate the effect of a course of aerobic exercise and vitamin D supplementation on the psychomotor function of elderly women with sleep disorders. Based on this, 42 people were selected in an accessible and targeted manner with an age range of 60-70 years. They all suffered from insomnia. Subjects were randomly divided into four groups: aerobic exercise, aerobic exercise-vitamin D supplement, vitamin D supplement and control group. Vitamin D intake in both groups was taken as 2000 units daily. The Physical Activity Readiness Diagnostic Questionnaire (PARQ) was used to know the level of physical fitness of the subjects and the Gibson 24-hour diet recall questionnaire the day before the pre-test and post-test. The Pittsburgh Sleep Quality Scale was used to extract the sleep profile. COG psychomotor test was also used to assess cognitive and mental components and information processing. The results showed that the aerobic, supplement and aerobic-supplement groups had a significant improvement in selective attention and reaction time. Also, the aerobic-supplement group had a significant improvement in selective attention and reaction time compared to the aerobic group and the supplement group. Aerobic exercise along with vitamin D supplementation seems to improve the motor and motor function of older women. Therefore, vitamin D supplementation and aerobic exercise in interaction are recommended for older women.

The aim of the current study was to determine the effect of two types of aerobic exercises on static and dynamic balance of the elderly women. 36 elderly women (60 to 75 years old) were randomly assigned to three groups: 1) walking or jogging (n=12) 2) exercise in water (n=12) 3) control (n=12). Groups 1 and 2 participated in walking (jogging) and exercise in water program for 8 weeks, 3 session per week. The control group had their own daily activities and did not participate in any special kind of sports during this program. Sharpened Romberg and stick balance tests were used to measure the dynamic and static balance. Analysis covariance test (SPSS21) was used to check research hypotheses and to determine the difference among the groups. The results showed significant differences in posttest scores between experimental and control groups (P˂0.05). The results also showed that the group 1 (walking and jogging) gained more scores in dynamic and static balance than the group 2 (exercise in water). It seems that both types of the aerobic exercises especially walking and jogging are appropriate for decreasing the difficulties of this group and can be used as an exercise program in training centers.

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.

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.

Perceptual-motor skills play a vital role in many tasks of daily life and sports skills. The measurement of coincidence anticipation timing ability is a method to evaluate perceptual and perceptual-motor skills. Thus, the main aim of the present study was to investigate the role of different organism, task and environment constraints in coincidence anticipation timing accuracy. For this purpose, 30 female adolescents (17-15 years old), young (20-40 years old) and elderly (60-80 years old) participated in 4 tests of coincidence anticipation timing. The tests included a coincidence anticipation timing task with green (1), blue (2), red (3) color background and an additional environment constraint (4) and participants had to coincide with the arrival of the stimulus in the target point and press the corresponding key. For data analysis, mixed ANOVA (3*4), 4 one-way ANOVA and 3 ANOVA with repeated measures were used for each group with adjusted Bonferroni. Statistical analysis showed a significant difference in test 1, 3 and 4 (P≤0.0125). Also, all groups showed a significant reduction in performance when the background color changed from green to red and the addition of the secondary task (P≤0.017). In addition, results indicated that the elderly group had the weakest performance compared with the adolescent and young groups and the reason might be a weakness in perceptual-motor systems related to age increase. Finally, different coincidence anticipation training programs were recommended for athletes, elderly and patients with perceptual-motor system weakness.

The aim of the present study was to determine the effects of the number of training sessions in a week on psychological factors and memory of sedentary elderly. For this purpose, 45 sedentary male elderly (mean age, 73.15±6.54 years; height, 166.5±3.10 cm; weight, 64.45±4.06 kg; body mass index (BMI), 23.49±1.51 kg/m2) were voluntarily selected and divided into two training groups and one control group with their own desire. The 8-week training program in two-session group consisted of running with intensity of 40-55% of maximum heart rate for 2 sessions a week. Subjects in four-session group used a training program with similar intensity of two-session group for 4 sessions a week. Depression, anxiety, happiness and memory status were measured using the Beck Depression, Beck Anxiety, Oxford Happiness and Wechsler Memory tests. Data were analyzed using paired t test and one-way ANOVA (P<0.05). The results showed a significant improvement in psychological factors and memory in experimental groups compared with the control group (P<0.05). Subjects who had practiced four sessions a week showed more improvement in depression, anxiety, happiness and some memory factors. Generally, both training programs had useful adaptation and increased number of training sessions has more influence in the improvement of psychological factors and memory in the elderly.

In recent years, researchers have become interested in examining the effect of PETTLEP imagery on motor performance and how PETTLEP imagery can improve the performance. The aim of this study was to compare the effect of PETTLEP imagery and balance practice on dynamic balance in the elderly. Participants were 42 male elderly in Arak city. They were divided into 4 groups based on the scores of dynamic balance pretest. In order to measure dynamic balance, Bass and Star Balance tests were used. Homogeneous training groups included PETTLEP imagery, balance practice, mixed practice (balance practice and PETTLEP imagery practice) and control group. All groups except for the control group practiced 3 sessions (each session 45 min.) a week for 6 weeks. MANOVA with repeated measures was used to analyze the data (P≤0.01). Results showed the mixed and balance practice groups significantly improved in Bass and Star dynamic balance (P=0.000, P=0.001, P=0.000, P=0.000). PETTLEP imagery and control groups showed no significant improvement in Bass and Star dynamic balance (P=0.24, P=0.53, P=0.36, P=0.28). Also, the mixed group had more improvement in Bass and Star dynamic balance than balance practice group (P=0.002, P=0.004). Overall, these results showed that PETTLEP imagery practice along with physical training improved dynamic balance in male elderly, but PETTLEP imagery alone did not affect the improvement of dynamic balance in the male elderly.

The purpose of present study was to determine the effect of different levels of balance task difficulty and visual feedback on balance in elderly women. Fourteen healthy elderly women (mean age 57/65 yr) were selected voluntarily. Participants were asked to stand still on a stability platform under each of two conditions (with visual feedback and without visual feedback) in three levels of difficulty (6, 8, 10). Stability index scores (Overall, Anterior- Posterior and Medial- Lateral) were calculated by Biodex Balance System. Duration of each test was 20 seconds and rest times were 20 seconds. Results showed that with increasing task difficulty, score of Medial- Lateral balance (p= 0/02) increased significantly. In addition, There was a significant reduction in the scores of Overall balance (p= 0/001), anterior - posterior balance (p= 0/01) and medial - lateral balance (p= 0/01) in visual feedback condition compared with without feedback condition. Overall, the results of this study showed that increasing task difficulty increases postural sway and availability of visual feedback can improve balance and reduce the postural sway.

Cognitive performance such as prediction and reaction time changes along with aging. It seems that regular lifetime physical activity depends on the delay of these factors. This study aimed at investigating the effect of Pilates training on the improvement of motor performance of sedentary elderly men in Kermanshah city. 40 sedentary elderly men (mean age 72.15 ± 6.54 years) were selected from the senior citizen centers in Kermanshah and were divided into two groups of experimental and control randomly. The experimental group performed Pilates protocol for 8 weeks. Both groups participated in the pretest and posttest of cognitive performance. The data obtained from the pretest and posttest were analyzed by paired samples t test and independent t test was used to compare the posttests of both groups. The results showed that Pilates group outperformed the control group significantly in their cognitive status and reaction time in the posttest (P˂0.05), but there was no significant difference in prediction between these two groups. The patterns of these results suggested that Pilates exercises could improve the elderly's cognitive performance.

Postural control requires the integration of sensory information in the visual,vestibular, and senses the body systems. Also research has shown that the sensorysystems involved in postural control, decreased with increasing age. The aim ofthis study was to investigate the effects of age and manipulation of sensoryinformation on the postural control. For this purpose, displacement of the anterior- posterior, middle – lateral and speed center of pressure (COP) 22 elderly (59/54± 2/31 year) and 25 young men (23/12±3/26 year) that selected based on targetand availability from Shahid Chamran University students and staff in fourdifferent sensory conditions including 1) open eyes an hard surface 2) eyes openon soft surface3) eyes closed on hard surface 4) eyes closed on soft surface duringthree 30-second efforts with 5 min rest intervals between efforts evaluated. Afterinvestigating the data normality with kolmogorov smirnov and equality of varianceusing the leven test, data using multivariable variance analysis and one-wayvariance analysis was analyzed. Significant differences was observed betweenyoung and elderly groups in all conditions, also removes the visual and plantarproprioceptive information lead to increased sway in the two groups that increasewas greater in the elderly than in young group. This results indicate theimportance of visual information and plantar proprioceptive in postural control,especially in the elderly.
