1. Acute effects of Expiratory Positive Airway Pressure (EPAP) on different levels in ventilation and electrical activity of sternocleidomastoid and parasternal muscles in Chronic Obstructive Pulmonary Disease (COPD) patients: a randomized controlled trial
ABSTRACT Objective To investigate the acute effects of EPAP on the activity of sternocleidomastoid (SCM), parasternal muscles and ventilatory parameters in COPD patients. Method Twenty-four patients with COPD were studied using surface electromyography (sEMG) and a ventilometer. Patients were randomly assigned to EPAP 10 cmH2O-EPAP10 or 15 cmH2O-EPAP15 for

2. Association between respiratory and postural adaptations and self-perception of school-aged children with mouth breathing in relation to their quality of life
Objective: To investigate the respiratory and postural adaptations associated with mouth and nasal breathing and to evaluate the associations of such adaptations in mouth breathers' self-perceived quality of life. Method: Cross-sectional study with mouth breathers (initial n=116 and final n=48) and nasal breathers (initial n=131 and final n=24) from element

3. Efeitos da facilitação neuromuscular proprioceptiva aplicada à musculatura acessória da respiração sobre variáveis pulmonares e ativação muscular em pacientes com DPOC
INTRODUÇÃO: A desvantagem mecânica induzida pela hiperinsuflação leva os pacientes com doença pulmonar obstrutiva crônica (DPOC) a usar a musculatura acessória da respiração. Os efeitos do alongamento destes músculos em pacientes com DPOC não são bem conhecidos. OBJETIVOS: a) Comparar a ativação dos músculos acessórios da respiração em pac

4. Strategy for respiratory exercise pattern associated with upper limb movements in COPD patients
INTRODUCTION: Upper limb exercises are frequently used in respiratory physiotherapy, with UL elevation and controlled inspiratory timing. However, the use of expiration during upper limb elevation appears to be a strategy that could minimize the action of accessory muscles in patients with chronic obstructive pulmonary disease. In this context, little is kno

5. Activation of human respiratory muscles during different voluntary manoeuvres.
1. This study used three techniques (bilateral phrenic nerve stimulation, motor cortex stimulation and quantitative electromyography) to assess the degree of activation of the diaphragm, intercostal-accessory muscles and abdominal muscles during postural tasks and respiratory manoeuvres. They included maximal inspiratory and expulsive efforts. 2. Bilateral p

6. Breathing abnormalities in sleep in achondroplasia.
Overnight sleep studies were performed in 20 subjects with achondroplasia to document further the respiratory abnormalities present in this group. Somatosensory evoked potentials (SEPs) were recorded in 19 of the subjects to screen for the presence of brainstem abnormalities, which are one of the potential aetiological mechanisms. Fifteen children aged 1 to

7. Limitations of measurement of transdiaphragmatic pressure in detecting diaphragmatic weakness.
Intrathoracic (oesophageal), intra-abdominal (gastric), and transdiaphragmatic (Pdi) pressures were studied in 20 untrained, healthy subjects during a full inspiration and repeated maximal static inspiratory efforts. The pattern of pressure generation during these two types of respiratory manoeuvre was highly reproducible in each subject. By contrast, it var

8. Respiratory muscle recruitment during selective central and peripheral chemoreceptor stimulation in awake dogs.
1. In four awake dogs we measured EMG activity of three inspiratory and four expiratory muscles during sustained central chemoreceptor stimulation (CO2 inhalation), and peripheral chemoreceptor stimulation (intravenous infusion of almitrine bismesylate (almitrine)). By using this selective pharmacological stimulation of the peripheral chemoreceptors and reve

9. Reinnervation of skeletal muscles by vagal sensory fibres in the sheep, cat and rabbit.
Fibres of the sterno-cleido-mastoid (s.c.m.) muscle normally innervated by the accessory nerve have been reinnervated by afferent fibres of the vagus nerve after supranodose vagal-accessory nerve anastomoses or direct implantation of the vagus nerve into the s.c.m. in cats, rabbits and sheep. The afferent fibres contributing to this reinnervation were confir

10. Role of excitatory amino acids in the generation and transmission of respiratory drive in neonatal rat.
1. The involvement of excitatory amino acids in the generation and transmission of rhythmic respiratory drive was studied in an in vitro neonatal rat brain stem-spinal cord preparation. The subclasses of excitatory amino acid receptors studied included: (i) N-methyl-D-aspartate (NMDA) receptors, (ii) (R, S)-alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic
