Comparison of Box Breathing and Rhythmic Breathing Techniques in Patients With Asthma (BRAS)

17 juli 2026 bijgewerkt door: Riphah International University

Comparative Effects of Box and Rhythmic Breathing Techniques on Dyspnea, Pulmonary Functions, and Quality of Sleep Among Asthmatic Patients

Asthma is a chronic respiratory disease that can cause breathing difficulties, reduced lung function, and poor sleep quality. Breathing exercises are increasingly used as non-pharmacological interventions to improve respiratory symptoms and overall well-being in individuals with asthma.

This study aims to compare the effects of two breathing techniques, Box Breathing and Rhythmic Breathing, on dyspnea (breathlessness), pulmonary function, and quality of sleep in patients with asthma. Participants with asthma will be randomly assigned to receive either Box Breathing or Rhythmic Breathing exercises in addition to standard care. Both interventions will be performed three times per week for eight weeks.

The primary outcomes of this study include changes in dyspnea severity, pulmonary function measured by spirometry, and sleep quality assessed using validated questionnaires. The findings of this study may help determine which breathing technique is more effective and provide evidence for incorporating structured breathing exercises into asthma management programs.

Gedetailleerde beschrijving

Asthma is a chronic inflammatory airway disease characterized by recurrent episodes of dyspnea, airflow limitation, and impaired quality of life. In addition to respiratory symptoms, many individuals with asthma experience sleep disturbances and reduced functional capacity. Breathing exercises have emerged as important non-pharmacological interventions that may improve respiratory control, autonomic regulation, and symptom perception.

Box Breathing and Rhythmic Breathing are structured breathing techniques that have shown potential benefits in respiratory rehabilitation. Box Breathing involves a controlled breathing pattern consisting of equal durations of inhalation, breath holding, exhalation, and breath holding. Rhythmic Breathing involves continuous and controlled breathing with a prolonged expiratory phase to promote respiratory efficiency and relaxation. However, limited evidence exists regarding the comparative effectiveness of these techniques in individuals with asthma.

The purpose of this study is to compare the effects of Box Breathing and Rhythmic Breathing on dyspnea, pulmonary function, and sleep quality among patients with asthma. Participants will receive standardized baseline respiratory care followed by either Box Breathing or Rhythmic Breathing interventions for eight weeks. The interventions are designed to improve breathing patterns, reduce breathlessness, enhance pulmonary function, and improve sleep quality.

This study aims to provide evidence regarding the effectiveness of structured breathing techniques as adjunctive interventions in asthma management. The findings may contribute to the development of evidence-based respiratory rehabilitation protocols and support the integration of breathing exercises into comprehensive asthma care programs.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Box Breathing Group A
Participants assigned to this arm received standardized baseline respiratory care followed by Box Breathing training. The Box Breathing technique consisted of inhaling for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and holding the breath again for 4 seconds. The intervention was performed for 20 minutes per session, three sessions per week, for eight weeks. Short rest periods were provided as needed during the intervention.
Gedragsmatig: Box Breathing
Participants assigned to the Box Breathing intervention received a structured breathing exercise protocol following standardized baseline respiratory care. The Box Breathing technique consisted of inhalation for 4 seconds, breath holding for 4 seconds, exhalation for 4 seconds, and a second breath hold for 4 seconds (4-4-4-4 pattern). The intervention was administered for 20 minutes per session, three sessions per week, for eight weeks. Short rest periods were permitted after every 5-6 breathing cycles as needed. The intervention was performed in a quiet environment and aimed to improve respiratory control, reduce dyspnea, enhance ventilatory efficiency, and promote autonomic regulation.
Experimenteel: Rhythmic Breathing Group
Participants assigned to this arm received standardized baseline respiratory care followed by Rhythmic Breathing training. The Rhythmic Breathing technique consisted of a controlled breathing pattern using a 4:6 ratio, with inhalation through the nose for 4 seconds and exhalation through the mouth for 6 seconds. The intervention was performed for 20 minutes per session, three sessions per week, for eight weeks. Short rest periods were provided as needed during the intervention.
Gedragsmatig: Rhythmic Breathing
Participants assigned to the Rhythmic Breathing intervention received a structured breathing exercise protocol following standardized baseline respiratory care. The Rhythmic Breathing technique consisted of a controlled breathing pattern using a 4:6 ratio, with inhalation through the nose for 4 seconds and exhalation through the mouth for 6 seconds. The intervention was administered for 20 minutes per session, three sessions per week, for eight weeks. Short rest periods were provided every 6-7 minutes as needed. The intervention was designed to promote respiratory efficiency, improve autonomic balance, reduce dyspnea, and enhance pulmonary function and sleep quality.

Maatregel Beschrijving
Tijdsspanne
Dyspnea Severity
Tijdsspanne: Baseline and 8 weeks (post-intervention)
Dyspnea severity will be assessed using the Modified Borg Scale, a numerical rating scale ranging from 0 to 10, where higher scores indicate greater perceived breathlessness.
Baseline and 8 weeks (post-intervention)

Tijdsspanne
Pulmonary Function (Forced Expiratory Volume in 1 Second [FEV₁])
Tijdsspanne: Baseline and 8 weeks (post-intervention)
Pulmonary function will be assessed using spirometry. Forced Expiratory Volume in 1 second (FEV₁) will be used to evaluate changes in lung function following the intervention.
Baseline and 8 weeks (post-intervention)
Sleep Quality
Tijdsspanne: Baseline and 8 weeks (post-intervention)
