RT Journal Article T1 A Secondary Analysis of Gender Respiratory Features for Ultrasonography Bilateral Diaphragm Thickness, Respiratory Pressures, and Pulmonary Function in Low Back Pain A1 Molina Hernández, Nerea A1 Rodríguez Sanz, David A1 López Chicharro, José A1 Becerro De Bengoa Vallejo, Ricardo A1 Losa Iglesias, Marta Elena A1 Vicente Campos, Davinia A1 Marugán Rubio, Daniel A1 Gutiérrez Torre, Samuel Eloy A1 Calvo Lobo, César AB The aim of the present study was to determine the gender respiratory differences of bilateral diaphragm thickness, respiratory pressures, and pulmonary function in patients with low back pain (LBP). A sample of 90 participants with nonspecific LBP was recruited and matched paired by sex (45 women and 45 men). Respiratory outcomes included bilateral diaphragm thickness by ultrasonography, respiratory muscle strength by maximum inspiratory (MIP) and expiratory (MEP) pressures, and pulmonary function by forced expiratory volume during 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC spirometry parameters. The comparison of respiratory outcomes presented significant differences (p < 0.001), with a large effect size (d = 1.26–1.58) showing means differences (95% CI) for MIP of −32.26 (−42.99, −21.53) cm H2O, MEP of −50.66 (−64.08, −37.25) cm H2O, FEV1 of −0.92 (−1.18, −0.65) L, and FVC of −1.00 (−1.32, −0.69) L, with lower values for females versus males. Gender-based respiratory differences were presented for maximum respiratory pressures and pulmonary function in patients with nonspecific LBP. Women presented greater inspiratory and expiratory muscle weakness as well as worse lung function, although these differences were not linked to diaphragm thickness during normal breathing PB MDPI YR 2024 FD 2024-06-03 LK https://hdl.handle.net/20.500.14352/106104 UL https://hdl.handle.net/20.500.14352/106104 LA spa NO Molina-Hernández N, Rodríguez-Sanz D, Chicharro JL, Becerro-de-Bengoa-Vallejo R, Losa-Iglesias ME, Vicente-Campos D, Marugán-Rubio D, Gutiérrez-Torre SE, Calvo-Lobo C.
