ELECTROVEST: Electro-Stimulation Vibratory Vest for Pulmonary Rehabilitation in Patients With Chronic Respiratory Diseases

A wearable vest device that delivers airway clearance therapy through high-frequency chest wall oscillation (HFCWO) combined with surface neuromuscular electrostimulation (EEM). The session includes a 2-minute warm-up phase at 4 Hz, 16 minutes of active stimulation at 8 Hz, and a 2-minute recovery phase at 4 Hz (total duration: 20 minutes). The intervention is administered during supervised physiotherapy sessions to promote mucociliary clearance and respiratory muscle activation in patients with chronic respiratory diseases.

A conventional airway clearance therapy using a commercial high-frequency chest wall oscillation (HFCWO) device (The Vest® Model 105 or AffloVest®). The session includes a 2-minute warm-up phase at 13 Hz, 16 minutes of treatment at 20 Hz, and a 2-minute cool-down at 13 Hz (total duration: 20 minutes). This intervention serves as the active comparator in the crossover trial.
