Purpose: This study was designed to determine the correlation between the diaphragmatic contraction pressure using diaphragmatic pressure belt (DiP Belt) and the ultrasound imaging of diaphragmatic motion and forced vital capacity. This study was conducted to confirm the usefulness of assessing the diaphragmatic function using the DiP Belt.
Methods: This study included 41 healthy subjects (13 males and 28 females). The diaphragmatic motion was measured using sonography, and the forced vital capacity (FVC) was measured using a portable digital spirometer device. After 2 weeks, the diaphragmatic contraction pressure was measured during maximal inspiration using the DiP Belt.
Results: The mean diaphragmatic contraction pressure (MDCP) and peak diaphragmatic contraction pressure (PMCP) using the DiP Belt were not significantly correlated with sonography imaging of diaphragmatic motion during quiet breathing but were significantly positively correlated with the diaphragmatic motion during deep breathing. Both the MDCP and PMCP were significantly positively correlated with FVC, forced expiratory volume in 1 second (FEV1), and peak expiratory flow (PEF). However, diaphragmatic motion was significantly positively correlated with FVC, FEV1, and PEF in only deep breathing.
Conclusion: The Dip Belt can provide valuable information about the diaphragmatic function, particularly ultrasound imaging of diaphragmatic motion and lung capacity.
