PURPOSE During high-intensity, exhaustive, constant-load exercise above 85% of maximal oxygen consumption, the diaphragm of healthy subjects can fatigue. Although a decrease in trans-diaphragmatic pressure is the most objective measure of diaphragmatic fatigue, possible extra-diaphragmatic muscle fatigue would not be detected by this method. The aim of the present study was to investigate the i...

OBJECTIVE The purpose of this study was to verify the reproducibility between two different observers of an analysis method for diaphragmatic displacement measurements using direct visualization with videofluoroscopy. PATIENTS AND METHODS 29 mouth breathing children aged 5 to 12 years from both genders were analyzed. The diaphragmatic displacement evaluation was divided in three parts: videof...

BACKGROUND Following diaphragmatic plication for unilateral paralysis, the effect on global chest wall function are unknown. Our hypothesis was that chest wall function would improve in both sides of the chest after plication of the paralysed side. CASE PRESENTATION Using Optoelectronic Plethysmography, total and regional chest wall volumes were measured in one patient before and after left d...

background & aim: the aim of this clinical trial study was to evaluate sleep quality in patients with chronic lung disease and the role of controlled breathing to improve the quality of sleep. methods & materials: sixty-four patients with chronic lung disease in two group (experimental and control group) enrolled in a 7 weeks. before interventions, the pittsburgh sleep quality index (psqi) and ...

This study investigated the impact of deep diaphragmatic breathing (DB) on blood gases, breathing pattern, pulmonary mechanics and dyspnoea in severe hypercapnic chronic obstructive pulmonary disease (COPD) patients recovering from an acute exacerbation. Transcutaneous partial pressure of carbon dioxide (Ptc,CO2) and oxygen (Ptc,O2) and arterial oxygen saturation (Sa,O2), were continuously moni...

Abstract Purpose: This study aimed to investigate the effects of diaphragmatic mobilization and breathing exercises on pain quality life in individuals with shoulder pain. Methods: A total 72 were included study. The randomly divided into 3 groups as Diaphragmatic Mobilization Group (DMG) (n=24), Breathing (DBG) control group (n=24). In addition classical physiotherapy treatment, applied by phy...

Integrated EMDR has two treatment phases. Phase 1 is designed for the alleviation of acute migraine symptoms. Phase 2 is designed to reduce the frequency, intensity, and duration of future migraine ep...

STUDY OBJECTIVE Mechanical ventilation (MV) is used clinically to treat patients who are incapable of maintaining adequate alveolar ventilation. Prolonged MV is associated with diaphragmatic atrophy and a decrement in maximal specific force production (P(O)). Collectively, these alterations may predispose the diaphragm to injury on the return to spontaneous breathing (ie, reloading). Therefore,...

The effect of muscle activation on muscle nitric oxide (NO) production remains controversial. Whereas NO release increases in in vitro activated muscles and in vivo limb muscles, diaphragmatic NO synthase (NOS) activity declines after 3 h of inspiratory resistive loading (IRL). We tested in this study the hypotheses that acute IRL decreases diaphragmatic NO derivatives levels and reduces protei...

The aim was to describe diaphragmatic behavior during postural limb activities and examine the ventilatory and stabilizing functions of the diaphragm. Thirty healthy subjects were examined in the supine position using a dynamic MRI system assessed simultaneously with specialized spirometric readings. The diaphragmatic excursions (DEs) were measured at three diaphragmatic points in the sagittal ...
