Quality of Life - Effects of a Physical Therapy Intervention to for Children and Adolescents With Asthma

Overview

Many children and adolescents with asthma have dysfunctional breathing, e.g. they use mainly upper chest muscles to breath and do not engage the diaphragma muscle when breathing. This can lead to a variety of breathin problems such as dizzyness, muscle tension, and limitations in ability to be physically active. As of today there is no guidelines for treatment or follow-up for these patients and there are very few well-perfomed studies evaluating if breathin retraining can improve breathing pattern. The aim of this study is to examine the effects of breathing training and advice on physical activity compared to only advice on physical activity in children and adolescents with asthma. The primary outcome is quality of life and secondary outcomes are dysfunctional breathing, asthma control, physical activity level and spirometry changes. This randomized controlled trial. Patients are identified at the paediatric lung clinic at Karolinska University Hospital, and patients aged 10-17 years who are reffered to see a physiotherapist for spirometry and exercise testing who have with asthma who have dysfunctional breathing are invited to participate. Assessments include the Paediatric Asthma Quality of Life Questionnaire, Parent Asthma Quality of Life Questionnaire, The Paediatric Nijmegen Questionnaire assessing symtpoms associated to dysfunctional breathing, the Childhood Asthma control test or the adult asthma control test. These questionnaires as completed by patients with or without their parents depending on their age at baseline, and after 4 weeks, 12 weeks and 24 weeks. At baseline and after 4 weeks an exercise tolerance test of 8 minutes performed on a treadmill and spirometry are performed. Interventions: Acitve intervention means diaphragmal breathing training 5 days a week for

Study Protocol for ClinicalTrials.gov Study Title Effects of Breathing Technique Training and Physical Activity Counseling on Quality of Life, Symptoms, Asthma Control, and Physical Activity in Children and Adolescents With Asthma: A Randomized Controlled Trial Brief Summary This randomized controlled trial aims to evaluate the effects of training in low-costal and diaphragmatic breathing techniques combined with counseling on physical activity according to FYSS, compared with standard care-physical activity counseling according to FYSS alone-on quality of life, symptoms related to dysfunctional breathing, asthma control, and physical activity levels in children and adolescents with asthma. Approximately 70 patients referred to a physical therapist at Karolinska University Hospital (Huddinge and Solna) will be invited to participate over one year. Participants will be randomized to either (1) an intervention group receiving extended physiotherapy including breathing training, inhalation technique, and individualized physical activity advice, or (2) a control group receiving standard physical activity recommendations according to FYSS. The primary outcome is health-related quality of life measured by the Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Detailed Description This study investigates whether adding structured breathing training to standard physical activity recommendations improves quality of life, dysfunctional breathing symptoms, asthma control, and physical activity levels among children and adolescents aged 10-17 with atopic and/or exercise-induced asthma. Participants randomized to the intervention group will receive training in low-costal/diaphragmatic breathing, individualized physical activity advice, and inhalation technique training. Diaphragmatic breathing will be practiced 3 times per day for 3-5 minutes. The control group will receive standard physical activity advice based on FYSS guidelines. Measurements will be taken before and after a 4-week intervention, and at 12- and 24-week follow-ups. Independent physiotherapists at each site will perform all assessments.
