Introduction: Falling is considered one of the most common problems of aging. Researchers believe that reducing the balance is - the main factor in falling the elderly. In this regard, the present study aims to comparison of the effectiveness of 8-week UF combined field training and tele-exercise program on static and dynamic equilibrium parameters of the ederly Man -
Method: This semi-experimental study was conducted in Isfahan, sixty healthy elderly men, aged 60-70 years old, had the ability to perform exercise activities, were selected through purposeful sampling and randomly divided into two experimental (field and tele-exercise) and control groups. Both experimental groups received intervention, exercise program sessions for 8 weeks, 3 sessions per week, and 90 minutes each session. A training program based on the UF training system was designed and implemented. Parameters related to static and dynamic balance were evaluated through a motion analysis device with seven cameras. For initial evaluations, a researcher-made questionnaire and a Mini Mental State Examination (MMSE) were used. Descriptive statistics were used for data analysis and their homogeneity and ANOVA for repeated measurements were used to analyze the data.  SPSS version 24 was also used to perform statistical processes.
Results: The results showed that all three experimental and field experiments (tele-exercise) and control with age (P = 0.26), height (P = 0.08), body weight (P= 0/92), body weight index (P = 0.95), fitness fitness index (P = 0/43), mental health index (P= 0/54), and general health (P = 0/63 = 0) are homologous. The use of a combination exercise program as a tele- exercise and field exercise significantly increased some of the static balance parameters such as COP Excursion AP(P= 0/023) and ML(P= 0/019), Path Length AP(P= 0/001) and ML(P= 0/001), COP Velocity AP(P= 0/001) and ML(P= 0/001) have a significant difference(P<0.05), This case was also obtained in the internal-external stability of the step width, which is one of the dynamic balance parameters(P<0.05). However, in the same period, in the group that did not practice the exercise program, there was no significant change in any of the parameters of static and dynamic balance (P>0.05).
Conclusion: Regarding the findings of the research, It can be deduced that regular and continuous use of a 8-week combined exercise program such as Tele-exercise and field exercise can be considered as a good alternative to field training programs due to the improvement of static and dynamic balance parameters. Meanwhile, Tele-exercises seem to be more effective for the elderly age group because of the reduction of dangers outside the home and placement in matched groups, and pave the way for healthy aging and healthy living in this period of life.

Introduction: Frequent falls in the elderly have a direct relationship with postural control and balance. The purpose of the present study was to investigate the effect of Concurrent cerebral transcranial direct current stimulation and neuromuscular coordination exercises on balance elderly people.
Method: This study was an experimental, pre- and posttest design. The participants of this study were 24 elderly 60-75 year old male and female who were selected by convenience sampling and randomly assigned to two “Intervention” (real) and “control” (Placebo) groups (n=12). After a preliminary assessment of equilibrium parameters by Computerized Dynamic Posturorghraphy apparatus, “Intervention” group received direct current stimulation over the cerebellum at 2mA and “Placebo” group received sham stimulation, twenty minutes each session in five days during two weeks. At each session, immediately after stimulation, participants performed half-hour equilibrium exercises on the Huber apparatus. After completing five sessions, the variables were re-measured. Data analysis performed using MANCOVA and ANCOVA and SPSS 23 software.
Results: The results of this study showed that current direct stimulation of the cerebral had significant effect on the postural control equilibrium variables in the first and fourth sensory condition (P<0.05). However, it did not have a significant effect on the stability of the elderly in the second, third, fifth, sixth sensory condition and composite balance (P>0.05). In addition, cerebral electrical stimulation with balance training improved postural control performance of visual system (P<0.05), but postural control performance of somatosensory system, vestibular system, and visual preference did not significantly improve (P>0.05).
Conclusion: The results of this study showed that cerebral TDCS with balance training has little beneficial effects on postural control and balance of elderly people and can, to a lesser extent, facilitate motor learning and improve motor adaptation.

Introduction: It is essential understanding causes of falls among the older adults in order to design effective interventions; therefore, the aim of the present study was to investigate the role of muscle weakness in balance and postural instability among older adults with and without a history of falls.Results: According to the inclusion and exclusion criteria, 23 articles entered the final review phase. Eighteen of the above twenty-three studies reported that lower-limb muscles play an important role in balance and postural stability, and five articles investigated the role of lower-limb muscles in balance and falls among the older adults.
Conclusion: It seems that muscle weakness is a risk factor for falls among the older adults. Both the distal and proximal muscles of the lower limb play an important role in the balance and fall among the older adults. Studies showed that upper-limb muscles play a more important role in balance, postural instability, and falls among the older adults than lower-limb muscles. Therefore, to prevent muscle weakness-related falls among the older adults, training programs should be considered to increase the muscle strength and thus to reduce the risk of falls in this age group and increase the number of active older adults in the society.
