BACKGROUND Current published guidelines on spirometry interpretation suggest an elevated FVC and FEV(1) > 100% of predicted with an obstructive ratio may represent a physiological variant. There is minimal evidence whether this finding can be indicative of symptomatic airways obstruction. METHODS Pulmonary function testing databases for a 4-year period were retrospectively reviewed. All tech...
Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive enough to show abnormalities before extensive damage, as seen in restrictive lung diseases. Therefore, we hypothesized that cardiopulmonary exercise testing (CPET) may be better t...
Spirometry is regarded as the only effective method for detecting pulmonary function test (PFT) indices. In this study, a novel impedance pulmonary function measurement system (IPFS) is developed for directly assessing PFT indices. IPFS can obtain high resolution values and remove motion artifacts through real-time base impedance feedback. Feedback enables the detection of PFT indices using onl...
Purpose: Dynamic Neuromuscular Stabilization (DNS) approach is developed based on neurodevelopmental kinesiology and reflex-mediated core stabilization concepts. But the outcomes of this approach remain unclear. So changes in some spirometry indices in response to DNS breathing exercises in sedentary students with poor posture will be explored. Methods: In this single-group pretest-posttest st...
