Electrovest®: A novel portable electro-vibratory device for airway clearance in chronic hypersecretory lung diseases

Year: 2025

Type: article

Abstract: BACKGROUND: Chronic respiratory diseases such as COPD, cystic fibrosis, and bronchiectasis are frequently associated with bronchial hypersecretion, leading to airflow obstruction and recurrent infections. Effective airway clearance techniques are essential but often limited by adherence, cost, and usability. RESEARCH QUESTION: To evaluate the clinical efficacy, safety, tolerability, and comfort of Electrovest®, a novel portable electro-vibratory device that integrates neuromuscular electrical stimulation (NMES) to promote thoracic vibrations in patients with chronic hypersecretory respiratory diseases. STUDY DESIGN AND METHODS: A randomized, controlled, crossover pilot study including 21 clinically stable patients with hypersecretory chronic respiratory diseases underwent two interventions: Electrovest® and The Vest®. Pulmonary, muscular, functional, and comfort parameters were assessed before and after each therapy. The trial was registered (NCT07175012). RESULTS: = 0.020). No muscle or renal injury was detected. Cough and Sputum Assessment Questionnaire (CASA-Q) scores improved in most domains. CONCLUSION: Electrovest® is a safe, well-tolerated, and effective alternative for airway clearance in chronic hypersecretory respiratory diseases. Its portability, comfort, and potential for home use may enhance long-term adherence compared to traditional systems.
