BACKGROUND the measurement of nasal inspiratory pressure, known as the sniff test, was developed as a new test of inspiratory muscle strength, mainly used in neuromuscular conditions. The test is easy to be performed and noninvasive. Despite the clinical importance of assessment of nasal inspiratory pressure a national equipment is not available to assess(More)
BACKGROUND The aim of the present study was to assess how volume-oriented incentive spirometry applied to patients after a stroke modifies the total and compartmental chest wall volume variations, including both the right and left hemithoraces, compared with controls. METHODS Twenty poststroke patients and 20 age-matched healthy subjects were studied by(More)
BACKGROUND In some people with asthma, expiratory airflow limitation, premature closure of small airways, activity of inspiratory muscles at the end of expiration and reduced pulmonary compliance may lead to lung hyperinflation. With the increase in lung volume, chest wall geometry is modified, shortening the inspiratory muscles and leaving them at a(More)
The aim of the study was to determine the acute effects of positive expiratory pressure (PEP) on breathing pattern, operational volumes and shortening velocity of respiratory muscles on patients with Parkinson's disease. It was evaluated 15 patients and healthy controls, by optoelectronic plethysmography, using PEP in three different levels (10, 15 and(More)
BACKGROUND Breathing exercises have been widely used worldwide as a complementary therapy to the pharmacological treatment of people with asthma. OBJECTIVES To evaluate the evidence for the efficacy of breathing exercises in the management of patients with asthma. SEARCH METHODS The search for trials led review authors to review the literature available(More)
BACKGROUND Pneumonia is an inflammatory lung disease and it is the greatest cause of deaths in children younger than five years of age worldwide. Chest physiotherapy is widely used in the treatment of pneumonia because it can help to eliminate inflammatory exudates and tracheobronchial secretions, remove airway obstructions, reduce airway resistance,(More)
We reasoned that the application of positive pressure through air stacking (AS) technique could cause gas compression and the absolute lung volumes could be estimated. The aim of this study was to estimate the amount of gas compression (ΔV comp) during AS in healthy subjects positioned at 45° trunk inclination and verify if the simultaneous measurements of(More)
INTRODUCTION The aim of this review is to evaluate the effectiveness of educational interventions on improving the control of blood pressure in patients with hypertension. METHODS Randomised controlled trials including patients over 18 years of age, regardless of sex and ethnicity, with a diagnosis of hypertension (either treated or not treated with(More)
BACKGROUND Chronic venous insufficiency (CVI) is a common disease that causes discomfort and impairs the quality of life of affected persons. Treatments such as physical exercise that aim to increase the movement of the ankle joint and strengthen the muscle pump in the calf of the leg may be useful to reduce the symptoms of CVI. OBJECTIVES To assess and(More)
