This single-center, longitudinal, observational, prospective study aims to assess the applicability, adherence, and clinical impact of the Active Cycle of Breathing Technique (ACBT) with augmented reality support in patients with alpha-1 antitrypsin deficiency (AATD). A total of 50 adult AATD patients will be recruit from the Lung Function Unit of the University Hospital of Parma, meeting specific inclusion criteria. Participants will perform ACBT twice daily and walk at least 5000 steps per day. Clinical and functional outcomes including dyspnea perception, lung function, and quality of life, will be assessed before and after a six-week ACBT program. The study explores whether augmented reality enhance adherence and efficacy compared to conventional pulmonary rehabilitation (PR) methods. The expected outcome is improved adherence to PR.
