Paradoxical Motion on Sniff Test Predicts Greater Improvement Following Diaphragm Plication

BackgroundDiaphragm plication (DP) improves pulmonary function and quality of life for those with diaphragm paralysis or dysfunction. It is unknown whether differing degrees of diaphragm dysfunction as measured by sniff testing affect results after plication.MethodsPatients who underwent minimally invasive DP from 2008 to 2019 were dichotomized based on sniff test results: paradoxical motion (PM) versus no paradoxical motion (NPM); the latter...
