BACKGROUND Spinal muscular atrophy (SMA) affects respiratory muscles, which in addition to progressive scoliosis leads to respiratory impairment. Children with developing scoliosis are usually treated with spinal bracing to delay the progress. AIMS To assess the impact of body position and application of spinal bracing on lung function during tidal breathing in children with SMA. METHODS Lu...

BACKGROUND Cardiac involvement is common in myotonic dystrophy (MD) patients. Heart rate variability (HRV) is a simple and reliable technique that can be useful for studying the influence of the autonomic nervous system on the heart. OBJECTIVE Study heart rate variability in patients with type 1 MD. METHODS We studied HRV during 5-minute recordings in MD patients and in a healthy control gr...

Tidal expiratory flow limitation (EFL) may promote dynamic hyperinflation and contribute to chronic dyspnoea. The purpose of this study was to assess the contribution of EFL to chronic dyspnoea in adults with cystic fibrosis (CF). The presence of EFL was determined in 102 adults with stable CF (forced expiratory volume in one second (FEV1) 17.3-91.5% predicted) and 20 age-matched control subjec...

This study aims to validate the accuracy of a cervical traction therapy simulation model by comparing the intervertebral separations of six asymptomatic male adults when traction was applied to their cervical spines. The subjects were tested on two mechanical traction devices, representing the inclined and sitting positions. A total of 55 radiographic images of their cervical spines were taken ...

BACKGROUND In obese patients, reduced functional residual capacity exacerbated by supine position might decrease the effectiveness of pre-oxygenation and the tolerance to apnoea. The aim of this study was to compare the effect of body posture during pre-oxygenation, sitting or supine, on its effectiveness in obese patients. METHODS Forty obese patients (BMI > or =35 kg m(-2)) undergoing surge...

INTRODUCTION We assessed the effect of different positions of voiding on uroflowmetry findings in healthy men and in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS Ten men with symptomatic BPH and 10 healthy men were enrolled in this study. Urodynamic study was done for each subject in 3 positions: standing, crouching (the position used in the Iranian style toilets), ...

OBJECTIVES To evaluate the effect of posture change from the supine to the sitting position and before and after passive leg raising on maternal functional hemodynamics in pregnant women at 35-37 weeks' gestation, and to compare the changes in pregnancies that subsequently developed pre-eclampsia (PE) or gestational hypertension (GH) with those that remained normotensive. METHODS In 2764 sing...

OBJECTIVES To assess the nature of pulmonary dysfunction in type 1 diabetes and the relationship of pulmonary function tests to diabetic factors and complication. SUBJECTS AND METHODS Sixteen type 1 diabetic patients and 26 control subjects matched for age and sex were studied. We performed spirometry measurements and measured pulmonary diffusing capacity (DL(CO)) in sitting and supine positi...

Children with developing scoliosis are usually treated with spinal bracing to delay the progress. Aims—To assess the impact of body position and application of spinal bracing on lung function during tidal breathing in children with SMA. Methods—Lung fu...

Introduction: The purpose of the present study was to evaluate anthropometric characteristics of weight, sitting & standing height, cormic index and BMI in the adult residents of Qazvin, Iran. Methods: In this cross-sectional study, 300 adult inhabitants aged 18-55 years (180 males and 120 females) of Qazvin, Iran were evaluated. The participants were selected randomly and without any physic...
