Background: Optoelectronic plethysmography (OEP) is an innovative method of indirect
measurement of pulmonary ventilation, capable of breath-by-breath, three-dimensional, real …

Rationale The relationship of functional parameters such as lung mechanics, chest
kinematics, metabolism and peripheral and respiratory muscle function with the level of …

Questions: In people with chronic obstructive pulmonary disease, does the Manual
Diaphragm Release Technique improve diaphragmatic mobility after a single treatment, or …

Paradoxical inward displacement of the costal margin during inspiration is observed in many
chronic obstructive pulmonary disease patients at rest but its importance is unclear. The …

Singing involves distinct respiratory kinematics (ie movements of rib cage and abdomen) to
quiet breathing because of different demands on the respiratory system. Professional …

It is well known that the methods actually used to track thoraco-abdominal volume
displacement have several limitations. This review evaluates the clinical usefulness of …

Altered breathing pattern is an aspect of dysfunctional breathing but few standardised
techniques exist to evaluate it. This study investigates a technique for evaluating and …

Background. Dysfunctional breathing (DB) may contribute to disproportionate dyspnea and
other medically unexplained symptoms. The extent of dysfunctional breathing is often …

Chronic obstructive pulmonary disease (COPD) patients often show asynchronous
movement of the lower rib cage during spontaneous quiet breathing and exercise. We …

BACKGROUND/PURPOSE: There has been a lack of studies that have used both three-
dimensional analysis and imaging tools concurrently to describe lung volume changes and …
