Breathing Retraining Adjuncts - A Systematic Review
No full textBackground: The COVID-19 pandemic highlighted the importance of breath and the impact of deficiency of oxygen supply and desaturation on modern medicine. In such situations, positioning, breathing exercises, and counseling are critical to patient survival. Additionally, breathing exercises have been found effective in minimizing pulmonary complications and promoting early recovery in pre and post-surgical conditions. Therefore, this study aimed to identify the existing devices used as adjuncts in breathing retraining and assess their effectiveness in routine chest physiotherapy practice.
Method: Randomized controlled trials (RCTs) conducted until July 2022 were included in the review. The electronic databases MEDLINE, PEDro, CINHAL, PUBMED, and Google Patents were searched based on the PRISMA guideline\u27s criteria, and research articles studied devices as adjuncts to physiotherapy in respiratory disorders. Devices that can aid in inspiratory or expiratory exercises with or without resistance are available and can be used during physiotherapy as adjuncts to management. However, not all devices are found to be multifunctional.
Conclusion: The study found that devices with functionality involving inspiratory or expiratory exercises with or without resistance can be used during physiotherapy as adjuncts to management. However, not all devices are multifunctional, and further research is needed to identify the most effective devices for use in respiratory disorders
Innovative Breathing Retraining Device: Phase-4 Validation of Clinical Efficacy in Healthy Adults
No full textBackground: Breathing retraining devices are widely used to improve lung function, respiratory muscle performance and breathing efficiency. Conventional devices often lack adjustable resistance, meaningful visual feedback or ergonomic design, which can limit training quality and patient engagement. A novel breathing retraining device was developed through sequential phases involving need analysis, engineering design and accuracy validation. Objectives: The study aimed to evaluate whether the newly designed device could produce measurable improvements in pulmonary function and inspiratory performance, and to determine its usability and acceptability among adult users. Methods: A two-week intervention study was conducted on healthy adults. Participants performed structured breathing retraining using the device under supervised and home-based sessions. Pulmonary function, inspiratory performance and user experience were assessed before and after the intervention. Results: Participants demonstrated notable improvements in key pulmonary parameters, including an increase in forced expiratory volume and sustained maximal inspiration. Inspiratory performance improved consistently across all users. User experience ratings indicated high satisfaction, with positive feedback regarding comfort, visual feedback clarity and ease of resistance adjustment. Conclusion: The novel breathing retraining device effectively enhances pulmonary function and inspiratory performance while offering excellent usability. The findings support its potential application in pulmonary rehabilitation and justify further clinical trials in populations with respiratory impairment
Design and testing of breathing retraining device a multiphasic exploratory study in healthy subjects
No full textIntroduction and aim. Traditional spirometers are limited by bulkiness and lack of biofeedback, which can hinder their effec tiveness in pulmonary rehabilitation. This study aimed to evaluate the accuracy of an innovative breathing retraining device in measuring inhaled volume and assess user satisfaction compared to standard spirometers.
Material and methods. A multiphasic exploratory study was conducted with 102 healthy adults (aged 18–60 years). The study included three phases: need analysis through focus group discussions, prototype development using polycarbonate materials and 3D printing, and effectiveness testing. Inhalation exercises were performed with both the new device and a standard spi rometer. Primary outcomes were inhaled volume and marker displacement, with user satisfaction assessed via the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) questionnaire.
Results. The new device showed a strong correlation between inhaled volume and marker displacement (r=0.842, p<0.001). The mean inhaled volume was 2.07±0.61 liters, with a mean marker displacement of 5.19±0.59 cm. The mean QUEST 2.0 satis faction score was 3.54, indicating high user satisfaction.
Conclusion. The redesigned breathing retraining device not only addresses critical gaps in existing technologies but also offers a practical, user-friendly solution for pulmonary rehabilitation. By combining accuracy, real-time feedback, and portability, this innovation has the potential to redefine respiratory therapy standards in both clinical and home-based settings, paving the way for broader applications and improved patient outcomes
