Dysfunctional Breathing

We will structure the study's summary to provide a clear and accessible overview for patients, families, and healthcare providers. The research will examine young adult cigarette smokers aged 18 to 24 to estimate the prevalence of a dysfunctional breathing-compatible symptom pattern using the Nijmegen Questionnaire. Furthermore, the study will assess how nicotine dependence severity-measured via the Fagerström Test for Nicotine Dependence-and physical activity levels-assessed using the International Physical Activity Questionnaire-relate to this symptom burden. We will recruit participants through social media announcements and conduct face-to-face evaluations at Istinye University. The project will employ hierarchical linear and binary logistic regression models, adjusting for age, sex, and body mass index, to determine independent predictors of dysfunctional breathing. Ultimately, the findings will provide valuable insights into the combined impacts of smoking severity and physical activity on respiratory health in young adults.

The primary aim will be to understand whether a digital breathing biofeedback system can improve the outcomes of physiotherapist guided breathing retraining.

The aim of this study is to investigate the effects of smartphone addiction on postural problems and breathing control in healthy university students. Excessive smartphone use has been associated with forward head posture, thoracic postural changes, and musculoskeletal complaints. These postural alterations may negatively influence respiratory biomechanics and breathing control. However, the relationship between smartphone addiction, postural deterioration, and dysfunctional breathing symptoms has not been comprehensively investigated. Participants will complete questionnaires assessing smartphone addiction and breathing control, and posture will be evaluated using the New York Posture Rating Chart. Binary logistic regression analysis will be performed to determine whether smartphone addiction independently predicts postural problems. Additionally, multiple linear regression analyses will be conducted to examine the association between smartphone addiction, posture, and breathing control.

The Swiss Paediatric Airway Cohort (SPAC) is a national, prospective clinical cohort of children and adolescents who visit physicians in Switzerland for recurrent wheeze, cough, and exercise- or sleep-related respiratory problems. SPAC aims to answer important questions on clinical phenotypes, prognosis, diagnosis and treatment. SPAC is part of routine care, and only clinically indicated investigations are done. The comprehensive baseline assessment includes a detailed questionnaire to families, plus test results, diagnoses and treatments from hospital records. Follow-up is via monthly questionnaires the first 12 months and thereafter annual questionnaires to families, and data from follow-up visits. Currently, 4344 patients from 10 clinics and hospitals in Switzerland (Aarau, Basel, Bern, Chur, Horgen, Lausanne, Luzern, St. Gallen, Worb, Zurich) have been enrolled. SPAC provides real-life data on children visiting the Swiss health care system for common respiratory problems. It will provide a research platform for health services research, and for nested clinical and transitional studies.

In this study the efficacy of a pulmonary rehabilitation program tailored to the needs of patients with dysfunctional breathing (DB) will be investigated using cardiopulmonary exercise testing. The pulmonary rehabilitation program will be compared with physiotherapy which is currently the mainstream therapy of DB.

This observational study aims to investigate the relationship between dysfunctional breathing and physical fitness parameters in healthy adults aged 18-35. Participants will be evaluated using the Nijmegen Questionnaire to assess dysfunctional breathing symptoms, and their physical fitness will be measured using the ALPHA-FIT Test Battery. Respiratory muscle strength and pulmonary function will also be assessed. The findings may help healthcare professionals better understand dysfunctional breathing and develop targeted treatment programs.

The goal of this observational study with a cross-sectional design is to investigate what signs, symptoms and assessment which can describe and explain dysfunctional breathing in patients with post COVID-19 condition. The main question aims to answer which measurements can identify and asses dysfunctional breathing in patients with post COVID-19 condition? Participants for this study will be recruited from the ReCov cohort will be evaluated with diffrent measurments and questionnaires.
