A comparative study of the effect of ACBT (active cycle of breathing technique) versus postural drainage in pulmonary rehabilitation. A systematic review

Pulmonary rehabilitation includes various techniques such as the Active Cycle of Breathing Technique (ACBT), Autogenic Drainage, postural drainage, and breathing exercises. Previous research on achieving total lung function has primarily focused on the ACBT pattern or other physiotherapeutic interventions. This review aims to compare both techniques for pulmonary rehabilitation. Methods: Relevant literature was searched from databases such as MEDLINE (PubMed), CENTRAL of Cochrane Library, Web of Science and Physiotherapy evidence database. The inclusion criteria of articles were low-load BFRT, ACL reconstruction, randomized controlled trials, muscle strength and volume, and only full-text papers were included. Results: Ten randomized controlled trails (RCTs) met the objective and criteria. After the screening and review process, only six articles were included in the systemic review. Data extracted from these six articles showed inconclusive results when comparing the two techniques. Both techniques were found to be effective, especially when performed simultaneously, with some articles suggesting that ACBT may be more effective
