| Περίληψη: | Inspiratory muscle training (IMT) is widely used in rehabilitation, yet the accuracy of mechanical threshold devices has been only partially characterised. The aim of this study was to evaluate the validity and stability of the pressure delivered by the Threshold IMT® device (Philips Respironics) using independent calibrated instrumentation, with the measurement chain itself validated against a weighted-plunger reference method. Three units were tested on a bench equipped with a calibrated differential pressure transducer (YOKOGAWA EJA110E; full-scale (FS) error ≤0.055%), an ISO 5167-3-referenced differential flow meter (uncertainty <5%), and an industrial fan. Five measurements per nominal pressure level (9, 25, and 41 cmH (Copyright © 2026 The Authors. Published by Elsevier Ltd.. All rights reserved.) |
