This research was conducted with the aim of comparing the effectiveness of sensory-motor games and neurofeedback on the attention of children with attention deficit and hyperactivity disorder. Previous studies consider factors such as attachment style, mindfulness, personality traits, and family factors to be effective and believe that people with hyperactivity disorder are deficient in emotional self-regulation, i.e., management and control in this area. For this reason, investigating the problems of this group and focusing on the issue of attention and concentration is important and needs attention.

This research was conducted as a semi-experimental study and the subjects were selected from all 8 to 12-year-old children in Tehran with hyperactivity and were randomly assigned to experimental and control groups. 40 subjects were placed in three groups of sensory-motor games, neurofeedback, combined group and a control group, and IVA2 was used to measure attention before and after the interventions.

The results of this research were evaluated using analysis of covariance after meeting the presuppositions and showed that the amount of visual and auditory effects in sensory-motor, neurofeedback and combined games in the group and the control after removing the pre-test effect. They are significantly different. This result means that the intervention of sensory-motor, neurofeedback and combined games have significant effect on the amount of attention in the dimensions of listening, attention, processing speed, caution, stability, tolerance, perception, stability and sensori motor. It has two parts, visual and auditory.

Based on the findings, the combined approach of sensory-motor games and neurofeedback has a greater effect on children’s attention than the two approaches of sensory-motor games and neurofeedback seperately, and there is a significant difference between the two approaches of sensory-motor games and neurofeedback in terms of the effect on attention

 This study evaluated the effects of neuromuscular training compared with neurofeedback and neuromuscular training on brain waves, foot and ankle ability, and pain intensity of table tennis players with chronic ankle instability.

 This clinical trial study was conducted on 29 table tennis players with chronic ankle instability, which were randomly divided into combined neurofeedback+neuromuscular (Mean±SD age: 21.73±2.60 years, hieght: 173.42±5.57 cm, wieght: 77.10±10.42 kg) and neuromuscular groups (Mean±SD age: 22.14±2.53 years, Mean±SD height: 169.26±6.77 cm, Mean±SD weight:77.95±15.70 kg). ProComp Infiniti System and BioGraph Infiniti version 5 software were used to measure brain waves and perform neurofeedback protocol. The foot and ankle disability questionnaire and the visual analog scale were employed to assess foot and ankle ability and pain intensity, respectively. The rehabilitation protocol was performed for eight weeks. The paired t test and 1-way analysis of covariance were used for the data analyses.

 The paired t test results revealed a significant decrease in the amplitude of theta, alpha, and sensorimotor rhythm (SMR) waves in both groups (P<0.05) and an increase in the amplitude of the beta wave only in the combined group (P<0.05). In addition, ankle ability was significantly increased during daily activities and exercise in both groups (P<0.05). On the other hand, the results of a 1-way analysis of covariance indicated a significant difference between the two groups regarding theta and beta amplitudes and degree of ankle disability during exercise, and the improvement was greater in the combined group (P<0.05).

 According to the results, combined exercises (neuromuscular and neurofeedback) can be used as rehabilitation in table tennis players with chronic ankle instability to correct brain waves, improve leg and ankle ability, and reduce pain.

The spread of coronavirus not only threatens physical health but also negatively affects the mental health of society. The aim of this research was to compare the effectiveness of schema therapy and neurofeedback in reducing depression in people with a history of Covid-19.

The current research method was quasi-experimental with a multi-group pre-test-post-test design with a control group. The study population included all depressed people with a history of Covid-19 who visited counseling clinics in Tehran during the first 6 months of 1401. Among the mentioned population, 45 people were selected by convenience sampling method and a simple randomization was used to divide them into three groups of 15 people as the neurofeedback treatment group, schema therapy group and control group. They answered the Beck’s depression questionnaire in two stages: pre-test and post-test. Analysis of covariance using SPSS-25 software was used to analyze the data.

Results showed that the depression scores of the intervention groups in the post-test compared to the pre-test were significantly reduced, and this rate was higher in the schema therapy group than in the neurofeedback group (p<0.01).

Based on the results, both schema therapy and neurofeedback methods can help to reduce depression in people with a history of Covid-19, although it appears that schema therapy has been more effective. Therefore, these two treatments can be used to improve the mental health of the society

The use of new training for improve the learning of beginners in executive skills such as shooting is one of the topics of interest in recent researches. The aim of research was to investigate the effect of a course of resistance training and neurofeedback on improving shooting skills and neural performance of military beginners. For this purpose, 25 people (mean age 20 years and weight 73.8 kg) were randomly selected and using the pre-test-post-test plan, shooting score, and supraspinal nerve function. Using TMS, before and after 12 sessions of resistance training with SMR and Alpha, it was studied in five resistance, resistance-neurofeedback, neurofeedback, Sham, and control groups. Multiple variance analysis in the graphpadprism9 software showed that in intra-group changes, the shooting score in resistance-neurofeedback (P<0.0001), resistance (P = 0.0229), and neurofeedback (P = 0.0241) increased, and the amplitude decreased significantly in the resistance-neurofeedback (P = 0.0115), but latency increased only in resistance training (P>0.05). The follow-up test between groups in the post showed that the changes in the shooting score and the amplitude in the resistance-neurofeedback were not significantly different compared to other groups. Considering the importance of muscle strength and brain functions regarding the proper performance of the shooter and according to the results of this research, it can be said that the use of training methods to strengthen muscles and improve the function of brain waves related to shooting skills, probably at the same time Strengthening the supraspinal nerve function improves part of the learning process and skill implementation in this field.

New technologies in neuroscience like neurofeedback (NFB) is one of the growing and challenging issues. The aim of present study was to determine the effectiveness of NFB on the severity of gastrointestinal (GI) symptoms, depression, anxiety, stress and quality of life in irritable bowel syndrome (IBS).

This study is a double-blind clinical trial with a control group. Initial screening included 160 patients with IBS who were referred by the gastroenterologist. Thirty patients were randomly assigned to three groups of NFB intervention; placebo (Pseudo-NFD) and control group (GI drugs only). The groups completed the IBS Severity Scale (IBS-SSS), Depression, Anxiety and Stress Scale (DASS-42) and IBS Quality of Life Questionnaire (QOL-IBS) before and after the intervention. Data were analyzed using ANOVA.

The results showed that NFB and placebo had a greater and significant effect on reducing depressive symptoms and IBS severity compared to the drug alone (P < 0.05). The placebo group with the drug showed an increase in higher quality of life scores than the other groups (P < 0.05). There was no significant difference between the groups in stress and anxiety.

Findings support the use of NFB along with medication for IBS patients, which is associated with appropriate therapeutic relationship, to enhance the effectiveness of interdisciplinary interventions.

Balance ability is a critical component of independent daily activities among the elderly. Balance disorder is one of the major risk factors for falls and related complications. Therefore, this study was conducted with the aim of the the comparision of the effectiveness of neurofeedback training (NT) and exercise environmental affordances (EEA) on static and dynamic balance and the fear of falling in the elderly. This was a quasi-experimental study with pretest-posttest design with a control group. The statistical population of the current study included elderly men aged 60 to 80 years living in Ilam, Iran, among whom 36 people were selected based on inclusion and exclusion criteria, and randomly assigned into three 12-member groups of NT, EEA and control. In the pretest and posttest stages, the participants completed the Yardley et al.’s fall self-efficacy questionnaire-international form, and having completed the questionnaire, they performed the static (Carlsen et al.) and dynamic (Tsang et al.) balance task in 3 attempts. In the intervention phase (exercise), carried out in form of three 30-minute sessions per week for eight weeks, NT and EEA groups performed the relevant exercises, and control group carried out their usual and daily activities in this time. The data were analyzed using univariate analysis of covariance (ANCOVA) using SPSS-22 software. The results indicated that EEA and NT have a significant effect on posterior and central-lateral displacement of the center of pressure as well as the time to reach anterior-posterior, lateral stability and the time to reach total stability of elderly men. EEA had a significant effect on the risk of fear of falling, but NT did not have the same effect. Besides, the results revealed that EEA, compared to NT, had more effect on static balance (anterior-posterior displacement and central-lateral displacement of the center of pressure) and dynamic balance (the time to reach anterior-posterior stability, the time to reach lateral stability, and the time to reach total stability) in elderly men. According to the results of the present study, it is suggested to geriatric trainers and specialists to pay attention to the enrichment of the environment to improve the static and dynamic balance of the elderly and the risk of falling.

Math problem solving requires improving both details and generalities perception by the brain's parietal cortex and in turn, achieving this ability requires the development of cognitive abilities. The purpose of this study was to improve cognitive abilities in math problem-solving through combined neurofeedback and transcranial electrical stimulation therapy.

This study was a quantitative study of the single case type with the ABAB design. The statistical population was the ninth-grade high school students referring to two counseling centers in Karaj. Among them, 5 weak students in math problem-solving were selected purposefully and voluntarily. The entry criteria were age between 14 and 16 years, a math score below 13.5 from 20 in the previous semester. Furthermore, participants should not have a diagnosis of learning disorders and coexistence, medical treatment, and a math reinforcement course. The measurement tools were the fourth edition of the Wechsler IQ test, transcranial electrical stimulation devices, neurofeedback, and math exam scores between two academic semesters. The combined intervention of electrical stimulation and neurofeedback was performed for 50 minutes, two months, and twice a week with the aim of promoting alpha and theta waves and suppressing beta three waves in the parietal cortex. Percentage improvement formulas, Cohen's effect size, and visual analysis were used to analyze the data.

The results showed that the combined treatment was effective in the mentioned brain waves. On the other hand, cognitive factors in Wechsler's intelligence scale, including active memory, processing speed, perceptual reasoning, and verbal comprehension, as well as students' math exam scores showed a significant improvement.

The findings showed that transcranial stimulation of the parietal cortex and neuro-feedback brain training are able to increase the learning ability of students who have problems understanding the details and generalities of mathematics. Therefore, this non-invasive combined method can be used as an approach to improve the cognitive abilities of students who are weak in solving mathematical problems.
