The effects of adapted physical exercise during rehabilitation in patients with traumatic brain injury

Objectives: This study aims to investigate the effects of adapted physical exercise on the level of muscular ability and attention process in patients with traumatic brain injury (TBI). Patients and methods: Between September 2018 and November 2018, a total of 25 male patients with TBI (mean age: 41.1±9.7 years; range, 30 to 50 years) that occurred two years ago were included in this randomized-controlled study. The patients were divided into two groups as the experimental group (n=13) and the control group (n=12). The experimental group implemented a regular rehabilitation program and an additional program of adapted physical exercise. The control group implemented only a regular rehabilitation program (morning gymnastics and gymnastics for the brain). Motor and functional abilities were assessed by a Senior Fitness battery and Berg's balance scale. Attention process was assessed by a standardized d2 test. Results: A significant improvement in physical abilities (strength, flexibility and balance) and attention process was observed in both groups (p<0.01). The improvement was greater in the experimental group (p<0.01). Conclusion: Traumatic brain injury causes difficulties in the memory and executive functions of the body and impairs working ability. The short-term adapted physical exercise program can yield a positive change in working abilities of patients with TBI.

The Effect of Attention Process Training (APT-II) On Cognitive and Daily Life Functioning in Patients With a Mild Cognitive Impairment: A Randomized Controlled Trial

Introduction. Older adults with mild cognitive impairment (MCI) are at increased risk of developing dementia even if they do not meet the criteria for dementia. Executive control of working memory, which is implicated in divided attention, is often impaired in this population, and such impairment is a strong predictor of dementia. Slowing the development of dementia by enhancing cognitive and brain plasticity represents a current and future challenge for clinicians and researchers. Cognitive rehabilitation allows patients to compensate for cognitive deficits with the ultimate goal of reducing the impact of such deficits on everyday life. We aim to examine the effectiveness and generalization of an attention and working memory training program (Attention Process Training or APT-II) in improving cognitive and everyday functioning in patients with MCI by means of a single-blind, randomized controlled trial.Methods. Twenty-two MCI patients will be randomly assigned to either a "Cognitive Training with APT-II" group or a "Standard Care" group. Initially, patients will be administered a battery of standardized neuropsychological tests to ensure that they meet MCI criteria. The intervention will consist of a cognitive training program (APT-II) and will last 8 weeks (two sessions per week). One of the strengths of APT-II training is that it emphasizes the transfer of cognitive gains from training sessions to everyday life. To evaluate the treatment's effectiveness in improving cognitive and daily life functioning, cognitive and functional outcomes will be assessed just before, immediately after, 3 months after, and 6 months after the intervention program. A divided attention memory task performed in virtual reality will also be administered to evaluate the effects of APT-II training on the management of attentional resources in a relatively ecological situation. Perspective. If our results indicate an improvement in the cognitive and daily life performance of older adults with MCI, this non-invasive, low-cost technique may deserve increased consideration as a therapeutic intervention to delay or reverse cognitive decline an diminish the risk of developing dementia in this population.Trial registration.

A Study of Social Learning for 8th – grade Students on Studying English at SMP Muhammadiyah 12 GKB

Social learning is an essential learning as a part of activities to change the behavior through public action. This study investigates a study of social learning for 8th grade on studying English at SMP Muhammadiyah 12 GKB. To guide students learning, the teacher serves the activity through modelling so that teacher must have known the students’ need before going to the class. It includes observational learning for the students in which affected their attention process, retention process, motor reproduction process, and also reinforcement process. It adopted theory of bandura toward social learning. The subject research is 32 students at 8th grade, it uses descriptive qualitative research during the observation and interview. The result of study described the transcript of conversation that involved in the classroom activity. Therefore this study aims to show social learning for 8th grade students on studying English at SMP Muhammadiyah 12 GKB

Effects of Acute Visual Stimulation Exercise on Attention Processes: An ERP Study

Backgrounds: It remains to be determined whether visual stimuli during exercise differentially influence the attention process. The purpose of the present study was to examine if different color stimuli during aerobic exercise are associated with different attention processes. Methods: 22 college students completed a four 30-min running session during the presentation of different color stimuli (blue, green, red, and yellow) and without color stimulus on separate visits. The Kanizsa triangle task was administrated before and immediately after exercise to assess the attention process. Behavioral performance (accuracy and response time (RT)) and event-related potential (P2, N2b and P3a) were recorded during the test. Results: Valid/invalid cue RT during the Kaniza test performance was significantly faster following the presentation of color stimuli during treadmill exercise compared to the seated rest. During exercise, these changes were larger after green and yellow stimuli than red in invalid cue RT. P2, N2b and P3a amplitudes of green were significantly larger than the other colors for both valid and invalid cues. Red color showed the lowest P2 and P3a amplitudes for both valid and invalid cues among colors. Conclusion: The distinctive neurocognitive changes during aerobic exercise suggest different effects of color stimuli on visual search attention, attention capture, attentional orienting and processing speed. This study will be a first step to understand the optimal environmental setting during exercise for subsequent improvements in the attention process.

Peculiarities of the attention process at depressive disorders

362 patients with cognitive impairment in depressive disorders were examined: 123 patients with recurrent depressive disorder, 141 patients with bipolar affective disorder and 98 people with prolonged depressive reaction. Peculiarities of the process of attention of patients with depressive disorders were the presence of a decrease in concentration, stability and switching of attention, decrease in work efficiency and working capacity. The peculiarities of the functioning of attention indicators were determined for various types of depressive disorders, which can use as diagnostic criteria in the differential diagnosis of cognitive impairment in depressive disorders. Key words: cognitive impairment, depressive disorders, persistence, concentration and switching of attention, recurrent depressive disorder, bipolar depressive disorder, prolonged depressive reaction
