Effects of Yoga on Attention, Impulsivity, and Hyperactivity in Preschool-Aged Children with Attention-Deficit Hyperactivity Disorder Symptoms

A Systematic Review of Yoga as a Supportive Treatment for Children with Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) has been one of the leading causes of neuropsychiatric disorders among children, which is why it is extremely essential to have a clear understanding of the disease and the new and upcoming treatment options available. Yoga has been one of the most recently explored and newer techniques that have been employed in the treatment of this disorder. It has become extremely crucial to understand the importance of using supportive treatments in the management of ADHD owing to the innumerable side effects caused by stimulant medication and the growing demands of parental concern about starting their children on stimulant medication at a very young age. Through this review, we would like to shed light on how yoga helps improve the lives of children with ADHD and how it can be used as a supplementary therapy for children with ADHD. After thoroughly screening various articles on this topic, we selected a total of seven articles for this study to highlight the effect that yoga has had on the improvement of ADHD symptoms. Furthermore, we also highlight the impact of such interventions in a family-based environment and how they help improve the immediate environment of a child with this disorder, thereby facilitating the development of a conducive environment for growth. We also highlight how these interventions help control various miscellaneous symptoms among children, such as stress, depression, and anxiety, as these concomitant symptoms are often associated with ADHD. This review article helps explore how yoga has proved to be a very holistic approach to the management of children with ADHD.

Interventions to improve executive functions in children aged 3 years and under: A systematic review

BACKGROUND

Early executive functioning (EF) skills are foundational capabilities that predict school readiness, academic development and psychiatric risk. Early interventions enhancing these capabilities could have critical import in improving outcomes. However, to develop interventions, it is necessary to identify specific EF skills that will vary with child age. Thus, we aimed to examine the characteristics and efficacy of interventions targeting EF in infancy and early childhood up to age 3.

METHODS

A comprehensive search of PubMed, Embase, CINAHL and APA PsycINFO databases was performed for studies published before December 2022. Randomized and non-randomized studies of interventions designed to improve at least one EF skill in children ≤3 years were included. EF skills included attentional control, inhibition/self-regulation, activity initiation, working memory, cognitive flexibility, planning ability, problem-solving and performance monitoring. We independently extracted data, used the revised Cochrane Risk-of-Bias tool to assess the quality of the evidence and conducted Synthesis Without Meta-analysis (SWiM). The overall quality of the evidence and the strength of recommendations was determined using elements of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

Thirty-five studies met inclusion criteria (original n = 7467). Studies were highly variable in the EF skill targeted, target subject (i.e., child, parent and teacher), nature and dosage of the intervention, and timing of outcome assessment. Most interventions focused on improving impulse control and self-regulation. The overall quality of evidence was low to moderate with a high risk of bias, though six studies had low risk of bias but yielded mixed findings of efficacy.

CONCLUSIONS

The relatively small number of early EF intervention studies uses such variable methods that there is currently no converging evidence of efficacy to recommend a specific intervention. Thus, findings support the need for a more systematic, targeted approach to the design and implementation of early EF interventions for target populations.

Effects of yoga on impulsivity in patients with and without mental disorders: a systematic review

BACKGROUND

Yoga can be used as a complementary intervention to conventional treatments, whether pharmacological or non-pharmacological. Sustained practice of yoga can generate a series of benefits for individuals' quality of life and improve their physical fitness.

OBJECTIVE

To investigate the potential effects of yoga as an adjunct intervention in conditions involving impulse control issues, such as attention deficit hyperactivity disorder (ADHD), borderline personality disorder, bipolar affective disorder, and substance use disorders.

METHODS

We performed a systematic review of placebo-controlled, randomized trials of yoga in patients with impulsivity. PubMed, Web of Science, and Science Direct databases were searched for trials published up to January, 2023. Data were extracted from published reports and quality assessment was performed per Cochrane recommendations.

RESULTS

Out of 277 database results, 6 RCT were included in this systematic review. To assess the level of attention and impulsiveness, the following scales were analyzed: Barratt Impulsiveness, UPPS-P Impulsive Behavior scale, Conners' Continuous Performance Test IIª and Conners' Parent Rating Scale-Revised: Long.

CONCLUSIONS

Yoga didn't have a significant improvement in impulsivity when compared to placebo. There are many tools to assess impulsivity, but they mean different concepts and domains consisting in a weakness on comparison of yoga effects.

Writing about a stressful experience improves semantic clustering of memory in men, not women

Writing about negative experiences can produce multiple benefits, including improvements in mental and emotional health. However, writing about negative experiences potentially be detrimental, as reliving and reexperiencing a negative memory can be painful. Although the emotional effects of writing about negative experiences are well established, the cognitive effects are less heavily explored, and no work to date has examined how writing about a stressful experience might influence episodic memory. We addressed this issue in the present study (N = 520) by having participants encode a list of 16 words that were organised around four semantic clusters, randomly assigning participants to write about an unresolved stressful experience (n = 263) or the events of the previous day (n = 257), and assessing their memory in a free recall task. Writing about a stressful experience did not influence overall memory performance; however, the stressful writing manipulation increased semantic clustering of information within memory for men, whereas the stressful writing manipulation did not influence semantic clustering of information within memory in women. Additionally, writing with more positive sentiment improved semantic clustering and reduced serial recall. These results provide evidence for unique sex differences in writing about stressful experiences and the role of sentiment in the effects of expressive writing.

Effect of Yoga among Children and Adolescents Diagnosed with Psychiatric Disorders: A Scoping Review

Background

Depression has been expected to be the second-leading cause of disability, followed by autism, attention and hyperactivity disorder, and learning disorder. Yoga therapy has found to be beneficial in managing psychiatric disorders.

Aim

The present study undertakes a scoping review of research on yoga therapy in psychiatric disorders among children and adolescents.

Methods

Online database was used to identify papers published 2004-2023, from which we selected 11 publications from the United States, Canada, Iran, India, and Australia that used yoga therapy as a primary outcome variable among participants aged 3 years or older.

Results

The papers reviewed were randomized controlled trials. All studies examined yoga therapy, but one study used mindfulness-based therapy and used few techniques of yoga therapy. The studies examined the effect of yoga therapy on early childhood and adolescence on various psychiatric symptoms such as stress, inattention, hyperactivity, anxiety, depression, and many more.

Conclusion

While the quality of studies is generally high, research on yoga therapy among children and adolescents with psychiatric disorders would benefit from careful selection of methods and reference standards, suitability for yoga therapy, and prospective cohort studies linking early childhood exposures with yoga therapy outcomes throughout childhood and adolescence.

A Parent-child yoga intervention for reducing attention deficits in children with congenital heart disease: the Yoga for Little Hearts Feasibility Study Protocol

INTRODUCTION

Preschoolers and school-aged children with congenital heart disease (CHD) are at higher risk of attention deficit hyperactivity disorder (ADHD) compared with the general population. To this day, no randomised controlled trial (RCT) aiming to improve attention has been conducted in young children with CHD. There is emerging evidence indicating that parent-child yoga interventions improve attention and reduce ADHD symptoms in both typically developing and clinical populations.

METHODS AND ANALYSIS

This is a single-blind, two-centre, two-arm trial during which 24 children with CHD and their parents will be randomly assigned to (1) a parent-child yoga intervention in addition to standard clinical care or (2) standard clinical care alone. All participants will undergo standardised assessments: (1) at baseline, (2) immediately post-treatment and (3) 6 months post-treatment. Descriptive statistics will be used to estimate the feasibility and neurodevelopmental outcomes. This feasibility study will evaluate: (1) recruitment capacity; (2) retention, drop-out and withdrawal rates during the yoga programme and at the 6-month follow-up; (3) adherence to the intervention; (4) acceptability of the randomisation process by families; (5) heterogeneity in the delivery of the intervention between instructors and use of home-based exercises between participants; (6) proportion of missing data in the neurodevelopmental assessments and (7) SD of primary outcomes of the full RCT in order to determine the future appropriate sample size.

ETHICS AND DISSEMINATION

Ethical approval has been obtained by the Research Ethics Board of the Sainte-Justine University Hospital. The findings will be disseminated in peer-reviewed journals and conferences and presented to the Canadian paediatric grand round meetings.

The Effect of Yoga on Anxiety, Attention and Social-Emotional Symptoms in Preschool Children: A Pilot Quasi-Experimental Study

This study evaluated the effectiveness of a short yoga session on behavioral and cognitive outcomes in preschool children. 72 children ages 4-6 from a local preschool were divided into an intervention group (n = 32), and a control group (n = 40) that completed a 15 min, age-appropriate yoga video consisting of interactive poses including: sun salutation, cat, cow, downward dog, upward dog, warrior, gorilla, etc. Three teacher-rated questionnaires and a cancellation task (Cx) were administered pre-intervention and post-intervention. Significant improvement was demonstrated in the yoga group on the teacher-rated questionnaire scores, but not the control group. Correct cancellations increased more in the yoga group compared to the control group, with remaining cancellation metrics demonstrating interaction effects. Findings indicated that a short yoga session improves measures of anxiety, social-emotional behavior, and attention in preschool children. This study suggests that a short 15-minute yoga session may improve behavior and attention in preschool children.

A Systematic Review of Yoga and Meditation for Attention-Deficit/Hyperactivity Disorder in Children

With attention-deficit/hyperactivity disorder (ADHD) being a prevalent disorder in childhood, it is essential to acknowledge the different adverse effects the disorder can have on the quality of life in children. Therefore, this systematic review focuses mainly on children. Medical therapy, especially stimulants, can have many side effects. Our systematic review aims to evaluate the potential of other non-medical treatment options for ADHD, such as yoga or meditation. We used PubMed and Google Scholar as databases for this systematic review. Using different combinations of medical subheadings (MeSH) and key terms, followed by the application of several inclusion/exclusion criteria and filters to narrow down our search. From an initial 51,675 articles, we selected 10 papers that passed our screening process and quality check to analyze in depth. Yoga and meditation positively affect various symptoms in children with ADHD, including attention, hyperactivity, and impulsive behavior. If done in family group sessions, it also benefited the parents and family dynamics, suggesting a potential option for family therapy. Furthermore, other psychological symptoms, such as anxiety or low self-esteem, appeared to be positively impacted by these interventions. Although yoga and meditation positively influenced children with ADHD, a more in-depth research is necessary with a more significant number of participants and over a more extended period of time. The results of the included studies suggest a substantial benefit. Nonetheless, as the number of studies is limited, at present yoga and meditation could be beneficial as supplemental therapy rather than being used alone as a therapy for ADHD.

Interventions for Executive Function in High-Risk Infants and Toddlers

This review summarizes the current state of evidence regarding interventions for executive function in high-risk infants and toddlers. Currently, there is a paucity of data in this area, with the interventions that have been studied highly variable in their content, dosage, target, and results. Self-regulation is the executive function construct targeted the most, with mixed results. The few studies that report later child outcomes in prekindergarten/school-aged children are encouraging, overall indicating improved cognition and behavior in the children of parents who received a parenting style intervention.

Yoga and Mindfulness for Social-Emotional Development and Resilience in 3-5 Year-Old Children: Non-Randomized, Controlled Intervention

Background

Early childhood is the key life course period for development of social-emotional skills, providing the foundation for school readiness and resilience in later life. Age-appropriate yoga and mindfulness programs may contribute to the development of critical skills in children. Young children from minoritized communities that face structural racism and health disparities may benefit from programs that support social-emotional development and contribute to future academic success. Systematic reviews of yoga interventions for young children have indicated the potential for effectiveness in supporting social-emotional development, executive function, and physical activity. However, studies of yoga and mindfulness with non-White children are sparse and, overall, the evidence base to date for such programs remains limited by non-controlled studies and the variable quality of studies evaluating programs in early childhood settings.

Methods

The analysis of data from a non-randomized, controlled intervention aimed to assess the effect of exposure to a yoga and mindfulness program for early childhood development of social-emotional skills in a majority Black/African American urban preschool setting in southeastern US. Children in the intervention received group yoga and mindfulness led by a certified children's yoga teacher who also had training and experience as a school teacher. Intervention participants engaged in activities for 20 minutes once per week for 32 weeks, while the control group had no yoga. The final sample included 579 in the historical control group and 122 in the intervention group.

Results

Results indicated that children who participated in the yoga and mindfulness program had higher total protective factor (TPF) subscores on the Devereux Early Childhood Assessment over time than children who did not receive yoga and mindfulness programming, and that the difference was statistically significant (P<0.05). Participation in the intervention group significantly predicted increases in initiative score, self-control score, and TPF score, as well as a decrease in the behavioral concerns.

Discussion

School based yoga and mindfulness programming can support social-emotional skills and resilience in young children. Additional studies with larger sample sizes and randomization are needed on use of yoga and mindfulness in young children for social-emotional development, particularly for Black/African American children and others from minoritized communities.

Effects of Mindfulness-Based Interventions in Children and Adolescents with ADHD: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

(1) Objectives: Mindfulness-based interventions have been receiving more attention in research for children with attention deficit hyperactivity disorder (ADHD). This systematic review and meta-analysis was conducted to synthesize the findings of randomized controlled trials of mindfulness-based interventions for children with ADHD. (2) Methods: A systematic review and meta-analysis of studies published in PsycINFO, PubMed, and Google Scholar was completed from the earliest available date until August 2022. (3) Results: The systematic review included 12 studies that met the inclusion criteria, and the meta-analysis included 11 studies. The overall effect sizes were g = 0.77 for ADHD symptoms, g = 0.03 for externalizing behavior problem, g = 0.13 for internalizing behavior problem, g = 0.43 for mindfulness, and g = 0.40 for parental stress for children with ADHD. (4) Conclusion: The results of this systematic review highlight the possible benefits of mindfulness-based interventions for children with ADHD.

Systematic Review and Meta-analysis: The Science of Early-Life Precursors and Interventions for Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

To evaluate which early neurocognitive and behavioral precursors are associated with the development of attention-deficit/hyperactivity disorder (ADHD) and whether these are currently targeted in early interventions.

METHOD

We conducted 2 systematic reviews and meta-analyses of empirical studies to examine the following: (1) early-life (0-5 years) neurocognitive and behavioral precursors associated with familial likelihood for ADHD, an early ADHD diagnosis/elevated ADHD symptoms, and/or the presence of later-childhood ADHD; and (2) interventions delivered to children aged 0 to 5 years targeting the identified precursors or measuring these as outcomes. Standardized mean differences (Hedges' g) and pre-post-treatment change scores (SMD) were computed.

RESULTS

A total of 149 studies (165,095 participants) investigating 8 neurocognitive and behavioral domains met inclusion criteria for part 1. Multi-level random-effects meta-analyses on 136 studies revealed significant associations between ADHD and poorer cognitive (g = -0.46 [95% CIs: -0.59, -0.33]), motor (g = -0.35 [CIs: -0.48, -0.21]) and language (g = -0.43 [CIs: -0.66, -0.19]) development, social (g = 0.23 [CIs: 0.03, 0.43]) and emotional (g = 0.46 [CIs: 0.33, 0.58]) difficulties, early regulatory (g = 0.30 [CIs: 0.18, 0.43]) and sleep (g = 0.29 [CIs: 0.14, 0.44]) problems, sensory atypicalities (g = 0.52 [CIs: 0.16, 0.88]), elevated activity levels (g = 0.54 [CIs: 0.37, 0.72]), and executive function difficulties (g = 0.34 [CIs: 0.05, 0.64] to -0.87 [CIs: -1.35, -0.40]). A total of 32 trials (28 randomized, 4 nonrandomized, 3,848 participants) testing early interventions that targeted the identified precursors met inclusion criteria for part 2. Multi-level random-effects meta-analyses on 22 studies revealed significant intervention-related improvements in ADHD symptoms (SMD = 0.43 [CIs: 0.22, 0.64]) and working memory (SMD = 0.37 [CIs: 0.06, 0.69]).

CONCLUSION

Children aged 0 to 5 years with current or later-emerging ADHD are likely to experience difficulties in multiple neurocognitive/behavioral functions. Early interventions show some effectiveness in reducing ADHD symptoms, but their effects on neurocognitive/behavioral difficulties require further study.

Yoga for the Management of Attention-Deficit/Hyperactivity Disorder

Yoga has been shown to play a role in reducing the symptoms associated with the inattentive and hyperactive-impulsive forms of attention-deficit/hyperactivity disorder (ADHD). The medical history and clinical findings for a nine-year-old patient presenting with difficulty paying attention and impulsive speech and actions at home and school are presented. After the diagnosis of combination type ADHD by assessment of DSM-5 criteria, both at home and school and through parent and teacher evaluations using National Institute for Children’s Health Quality (NICHQ) Vanderbilt Assessment Scales, the patient initiated a yoga training regimen. Six months after initiating the yoga training regimen, follow-up parent and teacher questionnaires revealed improvement in both the inattentive and hyperactive-impulsive symptoms. Literature sourced from the PubMed database to explore the efficacy of yoga for ADHD was used to support the research hypothesis that a structured yoga training regimen improves the symptoms associated with the inattentive and hyperactive-impulsive forms of ADHD, and thus, yoga is recommended as a management technique for individuals with ADHD.

The Interventions for Sleep Disorders in Children with Attention Deficit and Hyperactivity Disorder: A Narrative Review

BACKGROUND: Attention deficit and hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in childhood. Children with ADHD have more frequent comorbid sleep disorders than healthy children. The current methods of treating sleep disorders in ADHD children are still focused on pharmacological interventions which in fact only provide little benefit. AIM: This study aims to identify existing studies regarding the types of nonpharmacological and complementary interventions for sleep disorders in children with ADHD using a narrative review approach. METHODS: This was a narrative review. Inclusion criteria included articles in English and Bahasa, full-text articles, primary studies, and children with ADHD aged 18 years with or without comorbidities as the research sample, and the article having been published in the last 10 years. Searches were performed in several databases: PubMed, Springer, Web of Science, and Google Scholar. RESULTS: The result showed that programs for managing sleep disorder in ADHD are behavioral therapy, behavioral parent training (BPT), behavioral sleep intervention, neurofeedback, mind-body therapy, L-theanine supplementation, horse milk supplementation, and play therapy. The programs are found to be effective in improving sleep. CONCLUSION: The program most comprehensive with a high level of ease of implementation was BPT.

Recommendations for Measurement of Attention Outcomes in Preschoolers With Neurofibromatosis

Children with neurofibromatosis type 1 (NF1) are at increased risk for attention problems. While most research has been conducted with school-aged cohorts, preschool-aged children offer a novel developmental window for clinical studies, with the promise that treatments implemented earlier in the developmental trajectory may most effectively modify risk for later difficulties. Designing research studies around the youngest children with NF1 can result in intervention earlier in the developmental cascade associated with NF1 gene abnormalities. Furthermore, clinical trials for medications targeting physical and psychological aspects of NF1 often include individuals spanning a wide age range, including preschool-aged children. In a prior report, the REiNS Neurocognitive Subcommittee made recommendations regarding performance-based and observer-rated measures of attention for use in clinical trials and highlighted the need for separate consideration of assessment methods for young children. The observer-rated Attention-Deficit/Hyperactivity Disorder Rating Scale-Preschool version is recommended as a primary outcome measure. The NIH Toolbox Flanker, Dimensional Change Card Sort, and List Sort Working Memory tasks and Digits Forward from the Differential Ability Scales-2nd Edition (performance-based measures) are recommended as secondary outcome measures. Specific methodologic recommendations for inclusion of preschoolers in clinical trials research are also offered.

Yoga and Mindfulness Interventions for Preschool-Aged Children in Educational Settings: A Systematic Review

Early childhood and the pre-school stage of development constitute a dynamic period for acquisition of social-emotional competencies. Yoga and mindfulness practices (YMP) have become increasingly used in schools for social emotional learning, but less is known about their utility in early childhood settings. A systematic review using PRISMA guidelines was undertaken to explore the effect of YMP on social emotional function among preschool-aged children (3-5 years). The review resulted in identification of 1115 records, of which 80 full text articles were screened, with final inclusion of 16 studies. Included studies evaluated the effect of YMP on social-emotional functioning, and identified the potential for YMP to improve regulatory skills such as behavioral self-regulation and executive function. Among studies reviewed, 13 reported improvements in these domains, but quality appraisal indicated significant variability in risk of bias across studies, and heterogeneity of outcome measurements hindered comparison. Programs appeared to produce better results when implemented for at least 6 weeks and among children who had lower baseline social-emotional functioning. YMP constitute a promising strategy for social emotional development in early childhood settings, but additional rigorously designed studies are needed to expand understanding of how and why these programs are effective.

Psychological treatment strategies for challenging behaviours in neurodevelopmental disorders: what lies beyond a purely behavioural approach?

PURPOSE OF REVIEW

Challenging behaviour shown by individuals with neurodevelopmental disorders (NDDs) has a major negative impact. There is robust evidence for the efficacy of treatments based on applied behaviour analysis. However, such approaches are limited in important ways - providing only part of the whole solution. We reviewed the literature to provide an overview of recent progress in psychological treatments for challenging behaviour and how these advance the field beyond a purely behavioural approach.

RECENT FINDING

We identified 1029 articles via a systematic search and screened for those implementing a psychological intervention with individuals with NDD (or caregivers) and measuring the potential impact on challenging behaviour. Of the 69 included studies published since 2018, more than 50% implemented a purely behavioural intervention. Other studies could generally be categorized as implementing parent training, meditation, skill training or technology-assisted interventions.

SUMMARY

Greater consideration of the interplay between behavioural and nonbehavioural intervention components; systematic approaches to personalization when going beyond the behavioural model; mental health and broad social communication needs; and models that include cognitive and emotional pathways to challenging behaviour; is needed to advance the field. Furthermore, technology should not be overlooked as an important potential facilitator of intervention efforts.

Non-pharmacologic management of attention-deficit/hyperactivity disorder in children and adolescents: a review

Attention-deficit/hyperactivity disorder (ADHD) is a very common neurobehavioral disorder that affects children and adolescents with impact that persists beyond adolescence into adulthood. Medication and non-pharmacological treatments are evidence-based interventions for ADHD in various age groups, and this article will elaborate on the psychosocial, physical and integrative medicine interventions that have been studied in ADHD.

Early Minds: a pilot randomised controlled trial of a mindfulness program in early learning centres

BACKGROUND

Optimal mental health is critical for a child's learning and academic functioning. As a universal service, early education centres play an important role in promoting children's mental health. Social-emotional learning programs are efficacious in reducing behavioural difficulties, enhancing competence, and improving learning abilities. Mindfulness practices, known to promote health and wellbeing in adults, have been adapted to education programs for younger populations, including pre-school children. Despite an increasing use of mindfulness-based programs in pre-school settings, there is a limited number of randomised trials and paucity of data on implementation fidelity of these programs. 'Early Minds' is a mindfulness-based program developed by Smiling Mind for 3-5-year-old children. This paper describes a protocol of a pilot randomised control trial, evaluating the implementation of the program in early learning centres (ELCs, i.e. pre-schools) in Melbourne, Australia. The primary aim of this pilot study is to examine the feasibility, acceptability, and fidelity of the program. The secondary aims are to assess the acceptability of the design and measures and to investigate preliminary impacts of the program on child social-emotional outcomes.

METHODS

A convenience sample of six ELCs are recruited. Participants include educators, children, and their parents from 3- and/or 4-year-old ELC rooms. Upon completion of baseline surveys, rooms are randomly allocated to intervention and control arms by an independent statistician. 'Early Minds' is designed in a flexible delivery manner; meditations and activities are completed at least three times a week. Educators are trained in the program and have access to the activities and meditations on an app. Parents are encouraged to practice with their children at least three times a week. Educators document implementation fidelity throughout the 8 weeks of the program. Parents and educators complete follow-up surveys at 3 and 12 months post-randomisation, capturing feasibility and acceptability, child social-emotional behaviour and sleep, and educator, parent, and family wellbeing outcomes.

DISCUSSION

This pilot study is the first to assess a mindfulness-based program in ELCs in Australia. Data on feasibility and acceptability, implementation fidelity, and potential impact on children's behaviour will inform the design of adequately powered evaluation trials.

12 Weeks of Kindergarten-Based Yoga Practice Increases Visual Attention, Visual-Motor Precision and Decreases Behavior of Inattention and Hyperactivity in 5-Year-Old Children

The present study assesses the impact of Kindergarten-based yoga on cognitive performance, visual-motor coordination, and behavior of inattention and hyperactivity in 5-year-old children. In this randomized controlled trial, 45 children (28 female; 17 male; 5.2 ± 0.4 years) participated. Over 12 weeks, 15 children performed Hatha-yoga twice a week for 30 min, another 15 children performed generic physical education (PE) twice a week for 30 min, and 15 children performed no kind of physical activities, serving as control group (CG). Prior to (T₀) and after 12 weeks (T₁), all participants completed Visual Attention and Visuomotor Precision subtests of Neuropsychological Evaluation Battery and teachers evaluated children’s behavior of inattention and hyperactivity with the Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-IV. At T₀, no significant differences between groups appeared. Repeated measures analysis of variance revealed that following Bonferroni–Holm corrections yoga, in comparison to PE and CG, had a significant positive impact on the development on behavior of inattention and hyperactivity. Further, yoga has a significant positive impact on completion times in two visumotor precision tasks in comparison to PE. Finally, results indicate a significant positive effect of yoga on visual attention scores in comparison to CG. 12 weeks of Kindergarten-based yoga improves selected visual attention and visual-motor precision parameters and decreases behavior of inattention and hyperactivity in 5-year-old children. Consequently, yoga represents a sufficient and cost-benefit effective exercise which could enhance cognitive and behavioral factors relevant for learning and academic achievement among young children.

Metaanalyse zur Wirksamkeit achtsamkeitsbasierter Interventionen bei ADHS im Kindes- und Jugendalter

Zusammenfassung. Die vorliegende Metaanalyse berechnet die Wirksamkeit achtsamkeitsbasierter Interventionen bei Kindern und Jugendlichen mit ADHS gemäß empirischer Studien aus den Jahren 2008 – 2018. Als abhängige Maße werden die ADHS-Symptomatik, kognitive Leistungen (Aufmerksamkeitsleistungen in standardisierten Tests) sowie ADHS-spezifische Komorbiditäten berücksichtigt. Insgesamt wurden 16 Studien einbezogen. Im Ergebnis zeigt sich hinsichtlich der Reduktion der gesamten ADHS-Symptomatik eine große Effektstärke von d = 1.08. Zudem konnten eine Verringerung der Unaufmerksamkeitssymptomatik ( d = 0.47), mittlere Effekte auf Hyperaktivität / Impulsivität sowie moderate bis große Effekte auf komorbide internalisierende Störungen (Depressionen, Angststörungen) festgestellt werden. Die Metaanalyse liefert Hinweise darauf, dass achtsamkeitsbasierte Interventionen bei Kindern und Jugendlichen mit ADHS wirksam sind. Jedoch bestehen auf Ebene der Einzelstudien beträchtliche methodische Limitationen.

Effects of Mind⁻Body Exercises (Tai Chi/Yoga) on Heart Rate Variability Parameters and Perceived Stress: A Systematic Review with Meta-Analysis of Randomized Controlled Trials

Background: Heart rate variability (HRV) as an accurate, noninvasive measure of the Autonomous Nervous System (ANS) can reflect mental health (e.g., stress, depression, or anxiety). Tai Chi and Yoga (Tai Chi/Yoga), as the most widely practiced mind–body exercises, have shown positive outcomes of mental health. To date, no systematic review regarding the long-lasting effects of Tai Chi/Yoga on HRV parameters and perceived stress has been conducted. Objective: To critically evaluate the existing literature on this topic. Methods: Five electronic databases (Web of Science, PubMed, Scopus, SportDiscus and Cochrane Library) were searched from the start of the research project to July 2018. Study selection, data extraction, and study quality assessment were independently carried out by two reviewers. The potentially identified randomized controlled trials (RCT) reported the useful quantitative data that were included only for meta-analysis. Results: meta-analysis of 17 medium-to-high quality RCTs showed significantly beneficial effects on HRV parameters (normalized low-frequency, Hedge’s g = −0.39, 95% CI −0.39 to −0.56, p < 0.001, I2 = 11.62%; normalized high-frequency, Hedge’s g = 0.37, 95% CI 0.22 to −0.52, p < 0.001, I2 = 0%; low-frequency to high-frequency ratio, Hedge’s g = −0.58, 95% CI −0.81 to −0.35, p < 0.001, I2 = 53.78%) and stress level (Hedge’s g = −0.80, 95% CI −1.17 to −0.44, p < 0.001, I2 = 68.54%). Conclusions: Stress reduction may be attributed to sympathetic-vagal balance modulated by mind–body exercises. Tai Chi/Yoga could be an alternative method for stress reduction for people who live under high stress or negative emotions.
