Controlled Clinical Trial
Estimating breathing movements of the chest and abdominal wall using a simple, newly developed breathing movement measuring device.
The 3-dimensional (3D) distances of specific points on the chest and abdominal wall are useful for assessing the characteristics of breathing movement. This study aimed to determine whether the 3D distances on the chest and abdominal wall during deep breathing (DB) could be estimated using a newly developed breathing movement-measuring device (BMMD). ⋯ Linear regression equations provided adequate estimates of the 3D distances of markers on the chest and abdominal wall during DB. The results suggest that this BMMD is useful for quantitatively assessing DB movement of the chest and abdominal wall in healthy young males.

Controlled Clinical Trial
Vibration response imaging in idiopathic pulmonary fibrosis: a pilot study.
Vibration response imaging (VRI) is a novel imaging technique and little is known about its characteristics and diagnostic value in idiopathic pulmonary fibrosis (IPF). The aim of this study was to investigate the features of VRI in subjects with IPF. ⋯ VRI may be helpful to discriminate between IPF subjects and healthy individuals. Maximum energy frame and abundant crackles might serve as a diagnostic tool for IPF.
