Paralysis of the respiratory muscles in people with tetraplegia affects their ability to breathe and contributes to respiratory complications. Surface functional electrical stimulation (FES) of abdominal wall muscles can be used to increase tidal volume (V_{T}) and improve cough peak flow (CPF) in tetraplegic subjects who are able to breathe spontaneously. This study aims to evaluate the feasib...

This study explores the physiological correlates of a highly practiced Kundalini Yoga meditator. Thoracic and abdominal breathing patterns, heart rate (HR), occipital parietal electroencephalograph (EEG), skin conductance level (SCL), and blood volume pulse (BVP) were monitored during prebaseline, meditation, and postbaseline periods. Visual analyses of the data showed a decrease in respiration...

Introduction Navigator techniques allow the patient to breath freely during a whole heart coronary magnetic resonance angiography (WHCMRA) scan. However, long measuring times, caused by the necessity to synchronize the cardiac and the breathing cycle, and complex motion patterns lead to the suboptimal image quality. To overcome this problem, an abdominal belt (BELT), which can suppress the abdo...

OBJECTIVE The objective of this study was to investigate if a breathing technique could counteract the effects of hyperventilation due to a sustained attention task on shoulder muscle activity. BACKGROUND The trend towards higher levels of automation in industry is increasing. Consequently, manufacturing operators often monitor automated process for long periods of their work shift. Prolonged...

OBJECTIVE To investigate the effects of a diaphragmatic breathing training program (DBTP) on thoracoabdominal motion and functional capacity in patients with chronic obstructive pulmonary disease. DESIGN A prospective, randomized controlled trial. SETTING Academic medical center. PARTICIPANTS Subjects (N=30; forced expiratory volume in 1s, 42%±13% predicted) were randomly allocated to eit...

BACKGROUND Our aim was to compare the apparent diffusion coefficient (ADC) values of normal abdominal parenchymal organs and signal-to-noise ratio (SNR) measurements in the same patients with breath hold (BH) and free breathing (FB) diffusion weighted imaging (DWI). MATERIAL/METHODS Forty-eight patients underwent both BH and FB DWI. Spherical region of interest (ROI) was placed on the right h...

We recorded nasal gas flow, sleep stage, and abdominal muscle EMG pattern in 11 patients throughout the night after abdominal surgery, to examine the association between phasic activity of the abdominal muscles, sleep stage, and flow disturbance. We used a miniaturized data logging system, and obtained satisfactory records in eight patients. The data were divided into 30-s epochs. Each epoch wa...

A 65-year-old comatose man with metastatic melanoma developed rapidly cycling breathing, clusters of approximately 10 abdominal excursions within 3 seconds, interspersed by seconds apnea (video 1 and figure), mimicking myoclonus. Introduced Plum Posner1 as a respiratory pattern associated lesions in the low pons or high medulla, cluster breathing can occur without pontomedullary when alkalosis ...
