Breathing exercises for children with asthma

Efficacy of Bhramari pranayama and Om chanting on asthma control, quality of life, and airway inflammation in asthmatic children: an open-label randomized controlled trial

OBJECTIVES

To explore the efficacy of combination of Bhramari pranayama and om chanting as an adjunct to standard pharmacological treatment on asthma control, quality of life, pulmonary function, and airway inflammation in asthmatic children.

METHODS

Children (n = 110; 8-15 years) with uncontrolled or partly controlled asthma were recruited from the Pediatric Chest Clinic of All India Institute of Medical Sciences, New Delhi. Eligible participants were randomized to either home-based online Bhramari pranayama and om chanting plus standard treatment (YI + ST) group, or standard treatment (ST) alone group. Primary outcome measures were 12-week change in level of asthma symptom control; asthma control questionnaire (ACQ) score, spirometry indices, impulse oscillometry parameters, and pediatric asthma quality of life questionnaire (PAQLQ) score. Secondary outcome was a change in fractional exhaled nitric oxide (FeNO) levels at 12 weeks. Beginning from the enrollment, every participant was evaluated at 0, 2, 6, and 12 weeks.

RESULTS

After 12 weeks of intervention, higher proportion (68.2%) of children were found to have controlled asthma symptoms in the YI + ST group as compared to ST group (38.5%) according to per protocol analysis (p = 0.03). When compared to ST group, children in YI + ST group showed significantly lower ACQ score, higher PAQLQ score and reduced FeNO levels. No significant changes were observed for the lung function parameters.

CONCLUSION

Children practicing Bhramari pranayama and om chanting for 12 weeks have better asthma symptom control, quality of life, and reduced airway inflammation than those taking standard pharmacotherapy alone.

The Effect of Threshold Loading Training and an Innovative Respiratory Training Devices with Lower Torso Sports Training in Asthma Patients: A Randomized Trial

This study investigated the influence of two different devices with lower torso sports training in patients with asthma. Patients with asthma (n = 300) aged 55-60 years with FEV1/FVC ratio < 65%, who were repeatedly admitted to a pulmonary rehabilitation centre, participated. Patients were evaluated and randomized into two groups (experimental group 1; EXP-1, n = 150, who applied a conventional threshold loading device, and experimental group 2; EXP-2, n = 150, who used an innovative respiratory training device). Patients were included only if they met the global criteria for asthma. The experimental intervention period lasted 10 weeks with 3 weekly training sessions lasting 30-40 min. The maximal inspiratory pressure (PI, max), pulmonary function test, baseline dyspnoea index (BDI), oxygen saturation, and 6 min walking test (6MWT) performance were all measured at baseline and postintervention. Also, an assessment of the 1 min repeated exercise performance (leg extension and leg press) was performed. Moreover, St. George Respiratory Questionnaire was used to quantify the quality of life (SGRQ). Statistical analysis displayed significant favourable effects on 6MWT, leg press, and FRV1, for patients using both devices (EXP-1 and EXP-2, respectively) with lower torso athletic training. The other variables, weight SPO2 and SGRO, also showed no significant change in neither EXP-1 nor EXP-2. Thus, the new respiratory training device (EXP-2) appeared to be as effective as the conventional threshold loading device (EXP-1). In conclusion, our findings demonstrated beneficial effects of combining respiratory training with athletic training in asthma patients. Additionally, the validity of a unique respiratory training device for asthma patients was confirmed.

Acceptability of Serious Games in Pediatric Asthma Education and Self-management: Pilot Study

BACKGROUND

Asthma is the most common chronic pediatric disease. Despite existing tools to manage asthma, 40%-55% of children with asthma experience uncontrolled asthma. Serious games (SGs) represent a novel approach in promoting asthma education and self-management for children.

OBJECTIVE

In this qualitative pilot study with an embedded quantitative design, we aim to use focus groups and questionnaires to describe the perceived role of SGs in different aspects of asthma self-management by children and their parents. These aspects include asthma perception and knowledge, the impact of asthma and barriers to asthma self-management, and the support system for asthma self-management.

METHODS

A total of 5 children with asthma and their parents were invited to participate in an organized gaming session. Children and their parents completed a pregaming questionnaire on their medical history and asthma knowledge. Then, they were invited to test 4 original SG prototypes, after which the children answered a postgaming questionnaire on their asthma knowledge and perception of the SGs. Children and their parents subsequently participated in parallel focus groups, which were video-recorded or audio-recorded, transcribed verbatim, and analyzed by reaching consensus among members of the research team.

RESULTS

The mean age of the children was 10.3 (SD 1.5) years, with 20% (1/5) of the children being male. Qualitative data from the transcripts were coded into three separate domains: asthma self-management perception and knowledge, impact of asthma and barriers to asthma self-management, and support system for asthma self-management. We specifically explored the perceived roles of SGs within each domain. A key takeaway message was identified for each of these three domains: heterogeneity of asthma knowledge and the ability of SGs to encourage knowledge transfer through games, consequences and limitations of asthma and the ability of SGs to allow for identification and management of real-life situations through games, and insufficient support system and the ability of SGs to encourage playing with others for support and shared knowledge.

CONCLUSIONS

Our pilot study explored the role of SGs in the self-management of asthma, as perceived by children and their parents. Our findings support the acceptability of SGs in asthma education and self-management in pediatrics and the necessity for future development in this field.

Role of Breathing Exercises in Asthma-Yoga and Pranayama

Asthma is a chronic airway inflammatory disease that results from a complex interplay of genetic, environmental, and lifestyle factors. There is no cure for asthma, and the management is usually as per published guidelines. As in many chronic diseases conditions, various alternative or complimentary therapies have been tried. Of these, yoga and pranayama have gained wider attention in recent years. While the term yoga is a complex term encompassing eight limbs as per Patamjai in the yoga sutras, in simple terms, yoga is described as a combination of 'asana' (physical exercises) and 'pranayama' (breathing exercise). The term "asthma" has been derived from the Greek word "panting,", which indicates a rapid and shallow breathing. The main aim of yoga and pranayama in asthma is to synchronize and control breathing, thus decreasing hyperventilation. Besides this, they also decrease the stress/strain/anxiety, change in behavior, boost immunity, and improve strength/endurance of respiratory muscles that are helpful in any subject with asthma. There have been a good number of studies including clinical trials in children with asthma that have found some beneficial effects. In the present review, the physiology of yoga and pranayama, rationale for their use in children with asthma along with a summary of various studies conducted till date, have been discussed. These are followed by recommendations regarding their incorporation in the standard of care of children with asthma.

Do not forget asthma comorbidities in pediatric severe asthma!

Asthma is the most common chronic respiratory disease in childhood. The long-term goals in managing asthma aim to control symptoms and prevent exacerbations, as well as to reduce side effects of therapy and mortality disease-related. Most of patients have mild to moderate asthma and respond well to standard therapies. However, a minor proportion of children with asthma has severe disease that remains uncontrolled despite optimal adherence to prescribed therapy and treatment of contributory factors, including trigger exposures and comorbidities, which can mimic or worsen asthma and contribute to exacerbations and poor quality of life. Evaluation of comorbidities is fundamental to optimize the management of the disease in a subgroup of patients with poor responder asthma. The overall aim of this article is to describe characteristics of main pediatric severe asthma comorbidities reported in literature, giving clinicians tools to recognize and manage properly these conditions.

Intervenções de fisioterapia respiratória utilizadas durante a hospitalização de crianças e adolescentes com asma

Objetivo: descrever e comparar as intervenções de fisioterapia respiratória utilizadas para asma durante a hospitalização em três grupos etários pediátricos. Além disso, buscou-se investigar os motivos de escolha dessas intervenções.Métodos: a amostra foi composta por fisioterapeutas atuantes em hospitais que reportaram atender crianças e adolescentes com asma. Os profissionais responderam a um questionário online sobre dados pessoais, acadêmicos, profissionais e relativo às intervenções de fisioterapia respiratória utilizadas em lactentes, pré-escolares e escolares/adolescentes. As intervenções foram agrupadas em nove classificações: convencionais, manuais, baseadas em volume, oscilação oral de alta frequência/pressão expiratória positiva (OOAF/PEP), exercícios ventilatórios, ventilação não invasiva, técnica de expiração forçada (TEF), aspiração de vias aéreas superiores (VAS) e outras.Resultados: foram incluídos 93 fisioterapeutas, com idade entre 31 e 40 anos (47,3%) e do sexo feminino (87,1%). As intervenções mais utilizadas nos lactentes foram a aspiração de VAS (78,5%), a aceleração do fluxo expiratório (AFE) (50,5%) e a terapia expiratória manual passiva (TEMP) (45,2%). Nos pré-escolares, predominou a tosse (75,3%), a aspiração de VAS (52,7%), a AFE (51,6%) e a TEMP/expiração lenta e prolongada (ELPr) (50,5%). Já nos escolares/adolescentes, a tosse (83,9%), os exercícios expiratórios variados (73,1%) e a ELPr (57,0%) sobressaíram-se. Houve menor utilização (p<0,01) de OOAF/PEP, de exercícios ventilatórios e de TEF nos lactentes e, também, de métodos convencionais, manuais, aspiração de VAS e outras terapias (p<0,01) nos escolares/adolescentes. Os profissionais relataram utilizar essas intervenções por serem mais eficazes na prática clínica (78,5%).Conclusão: as intervenções manuais e as técnicas de expectoração visando à desobstrução brônquica foram as mais frequentemente utilizadas, tendo relação com a faixa etária e a escolha devido à efetividade na prática clínica.

Effects of physical therapy on lung function in children with asthma: a systematic review and meta-analysis

BACKGROUND

Asthma is a common chronic respiratory disease in children. In addition to medications, physical therapy is considered as a treatment strategy for asthma. We conducted this study to investigate the effects of physical therapy on lung function in children with asthma.

METHODS

Three databases were searched. We conducted the meta-analysis for the forced expiratory volume in the first second in percent predicted values [FEV1(%pred)], the forced vital capacity in percent predicted values [FVC(%pred)], and the peak expiratory flow in percent predicted values [PEF(%pred)] by using a random effect model.

RESULTS

Of the 6474 identified studies, 18 studies (16 in physical training, 2 in breathing exercise or inspiratory muscle training) were included in the systematic review and 11 studies (all in physical training) were included in the meta-analysis. The meta-analysis showed a significantly improved FVC(%pred) in the experimental group.

CONCLUSIONS

Physical training improved FVC(%pred) significantly in children with asthma. Further study is needed, especially on the effects of breathing exercise and inspiratory muscle training in children with asthma.

IMPACT

Our study reviewed the physical therapies for children with asthma and clarified whether and how these therapies affect them. Our study found that physical training improved the forced vital capacity in percent predicted values [FVC(%pred)] significantly in asthmatic children. Our study provided evidence that physical training could improve lung function in children with asthma, which is not identical to the Global Initiative for Asthma (GINA) guidelines.

12-Week Inspiratory Muscle Training Improves Respiratory Muscle Strength in Adult Patients with Stable Asthma: A Randomized Controlled Trial

This study aims to investigate and compare the effects of conventional breathing exercises and an inspiratory muscle training intervention on clinical symptoms in asthma patients. Sixty asthma patients (40–65 years old) were randomly assigned to either the conventional breathing exercises (BTE) or inspiratory muscle training (IMT) group for a 12-week intervention period. Outcome measurements were performed before and after the intervention, including the spirometry data, maximal inspiratory and expiratory pressures (PImax and PEmax), asthma control test, asthma control questionnaire, six-minute walk test, and three-day physical activity log, were recorded. PImax expressed as % of predicted value controlled for age and gender in healthy subjects (% predicted) increased by 16.92% (82.45% to 99.38%, p < 0.05) in the BTE group and by 29.84% (71.19% to 101.03%, p < 0.05) in the IMT group. Except for forced vital capacity, which was reduced in the BTE group, all other measured variables improved in both groups, and no statistically significant between-group differences were found. IMT appears to be more effective than breathing exercise intervention in promoting improvements in respiratory muscle strength. IMT may act as an alternative to conventional breathing exercises for middle-aged and elderly asthma patients.

Exercise/physical activity and health outcomes: an overview of Cochrane systematic reviews

BACKGROUND

Sedentary lifestyle is a major risk factor for noncommunicable diseases such as cardiovascular diseases, cancer and diabetes. It has been estimated that approximately 3.2 million deaths each year are attributable to insufficient levels of physical activity. We evaluated the available evidence from Cochrane systematic reviews (CSRs) on the effectiveness of exercise/physical activity for various health outcomes.

METHODS

Overview and meta-analysis. The Cochrane Library was searched from 01.01.2000 to issue 1, 2019. No language restrictions were imposed. Only CSRs of randomised controlled trials (RCTs) were included. Both healthy individuals, those at risk of a disease, and medically compromised patients of any age and gender were eligible. We evaluated any type of exercise or physical activity interventions; against any types of controls; and measuring any type of health-related outcome measures. The AMSTAR-2 tool for assessing the methodological quality of the included studies was utilised.

RESULTS

Hundred and fifty CSRs met the inclusion criteria. There were 54 different conditions. Majority of CSRs were of high methodological quality. Hundred and thirty CSRs employed meta-analytic techniques and 20 did not. Limitations for studies were the most common reasons for downgrading the quality of the evidence. Based on 10 CSRs and 187 RCTs with 27,671 participants, there was a 13% reduction in mortality rates risk ratio (RR) 0.87 [95% confidence intervals (CI) 0.78 to 0.96]; I2 = 26.6%, [prediction interval (PI) 0.70, 1.07], median effect size (MES) = 0.93 [interquartile range (IQR) 0.81, 1.00]. Data from 15 CSRs and 408 RCTs with 32,984 participants showed a small improvement in quality of life (QOL) standardised mean difference (SMD) 0.18 [95% CI 0.08, 0.28]; I2 = 74.3%; PI -0.18, 0.53], MES = 0.20 [IQR 0.07, 0.39]. Subgroup analyses by the type of condition showed that the magnitude of effect size was the largest among patients with mental health conditions.

CONCLUSION

There is a plethora of CSRs evaluating the effectiveness of physical activity/exercise. The evidence suggests that physical activity/exercise reduces mortality rates and improves QOL with minimal or no safety concerns.

Effects of Diaphragmatic Breathing on Health: A Narrative Review

Background: Breathing is an essential part of life. Diaphragmatic breathing (DB) is slow and deep breathing that affects the brain and the cardiovascular, respiratory, and gastrointestinal systems through the modulation of autonomic nervous functions. However, the effects of DB on human health need to be further investigated. Methods: The author conducted a PubMed search regarding the current evidence of the effect of DB on health. Results: This review consists of a total of 10 systematic reviews and 15 randomized controlled trials (RCTs). DB appears to be effective for improving the exercise capacity and respiratory function in patients with chronic obstructive pulmonary disease (COPD). Although the effect of DB on the quality of life (QoL) of patients with asthma needs to be investigated, it may also help in reducing stress; treating eating disorders, chronic functional constipation, hypertension, migraine, and anxiety; and improving the QoL of patients with cancer and gastroesophageal reflux disease (GERD) and the cardiorespiratory fitness of patients with heart failure. Conclusions: Based on this narrative review, the exact usefulness of DB in clinical practice is unclear due to the poor quality of studies. However, it may be a feasible and practical treatment method for various disorders.

Evidence for lifestyle interventions in asthma

Asthma is a chronic inflammatory airways disease, estimated to affect 300 million people worldwide. Asthma management plans focus on optimisation of asthma pharmacotherapy. Lifestyle interventions also hold great promise for asthma sufferers as they are accessible, low cost and have minimal side-effects, thus making adherence more likely. This review explores lifestyle interventions that have been tested in asthma, including improving nutrition, increasing physical activity and introduction of relaxation therapies such as yoga and massage therapy. Available evidence suggests a protective effect of increasing fruit, vegetable and wholegrain intake and increasing physical activity levels in asthma. Weight loss is recommended for obese asthmatic patients, as just 5–10% weight loss has been found to improve quality of life and asthma control in most obese asthmatic patients. Other lifestyle interventions such as meditation, yoga and massage therapy show promise, with positive effects on asthma seen in some studies. However, the study protocols are highly variable and the results are inconsistent. Additional research is needed to further develop and refine recommendations regarding lifestyle modifications that can be implemented to improve asthma.

Lifestyleinterventions may be key to living well with asthma, as increasing fruit, vegetable and wholegrain intake and exercise levels are shown to improve asthma. Future recommendations may include yoga, meditation and massage.http://bit.ly/2wbJp2J

Evaluation of a Choir as a Non-Medical Intervention for Children with Asthma: BreathStars

A shift in the current health policy has seen heightened focus on non-medical interventions which can be delivered out with formal health-care settings, to complement and enhance the clinical care of people with long-term conditions. Asthma is a common long-term condition managed by pharmacological and non-pharmacological interventions. Recent research activity has focused on the use of singing for respiratory health due to its similarity with the more well-known intervention of breathing exercises. The aim of this study was to determine if singing improved breathing in children with asthma. A realist evaluation study design with a mixed methods approach was adopted to evaluate a singing group for children aged 7-12. Results obtained through framework analysis of the data indicated notable improvement in asthma control with the added impact on self-esteem. Enjoyment of the singing group within a family centered approach was seen as a positive alongside the community benefit of wider asthma education. Lessons can be learnt from this evaluation which could inform future initiatives relevant to the current agenda of asset-based approaches such as social prescribing within the context of the current devolution of the health and social care budget in the North West of England.

Asthma - A Disease of How We Breathe: Role of Breathing Exercises and Pranayam

To describe the role of breathing exercises or yoga and/or pranayama in the management of childhood asthma. We conducted an updated literature search and retrieved relevant literature on the role of breathing exercises or yoga and/or pranayama in the management of childhood asthma. We found that the breathing exercises or yoga and/or pranayama are generally multi-component packaged interventions, and are described as follows: Papworth technique, Buteyko technique, Yoga and/or Pranayam. These techniques primarily modify the pattern of breathing to reduce hyperventilation resulting in normalisation of CO2 level, reduction of bronchospasm and resulting breathlessness. In addition they also change the behaviour, decrease anxiety, improve immunological parameters, and improve endurance of the respiratory muscles that may ultimately help asthmatic children. We found 10 clinical trials conducted in children with asthma of varying severity, and found to benefit children with chronic (mild and moderate) and uncontrolled asthma, but not acute severe asthma. Breathing exercises or yoga and/or pranayama may benefit children with chronic (mild and moderate) and uncontrolled asthma, but not acute severe asthma. Before these techniques can be incorporated into the standard care of asthmatic children, important outcomes like quality of life, medication use, and patient reported outcomes need to be evaluated in future clinical trials.

The physiological effects of slow breathing in the healthy human

Slow breathing practices have been adopted in the modern world across the globe due to their claimed health benefits. This has piqued the interest of researchers and clinicians who have initiated investigations into the physiological (and psychological) effects of slow breathing techniques and attempted to uncover the underlying mechanisms. The aim of this article is to provide a comprehensive overview of normal respiratory physiology and the documented physiological effects of slow breathing techniques according to research in healthy humans. The review focuses on the physiological implications to the respiratory, cardiovascular, cardiorespiratory and autonomic nervous systems, with particular focus on diaphragm activity, ventilation efficiency, haemodynamics, heart rate variability, cardiorespiratory coupling, respiratory sinus arrhythmia and sympathovagal balance. The review ends with a brief discussion of the potential clinical implications of slow breathing techniques. This is a topic that warrants further research, understanding and discussion.
