[Purpose] The aim of this study was to evaluate the changes in posture and respiratory functions depending on the duration of smartphone usage. [Subjects and Methods] Participants were randomly allocated to 2 groups: group 1 (subjects who used smartphones for <4 hours/day, n=25) and group 2 (subjects who used smartphones for >4 hours/day, n=25). The craniovertebral angles of all participants we...

[Purpose] The purpose of this study was to investigate the effects of thoracic spinal manipulation therapy on respiratory function including forced vital capacity and forced expiratory volume in one second in young healthy individuals. [Subjects and Methods] Thirty young healthy subjects recruited from a local university participated in this study. Subjects were randomly allocated into an exper...

OBJECTIVE To investigate the possible impact of long-term occupational exposure to hydrocarbons on respiratory health. METHODS Respiratory health was assessed by questionnaires, spirometry, and exhaled nitric oxide in 250 male workers from a company handling and distributing refined petroleum products (exposed) and 250 electricians (controls). Exposure to hydrocarbons was assessed by personal...

BACKGROUND The aim of this study was to clarify preoperative lung function as a prognostic factor for the long-term survival of, and to discuss the appropriateness of lobectomy for, patients with stage I non-small cell lung carcinoma who have poor preoperative pulmonary function. METHODS The study group consisted of 402 lobectomized patients with stage I non-small cell lung carcinoma treated ...

[Purpose] This study was aimed at assessing the effect of lumbar stabilization exercise on the pulmonary function of stroke patients. [Subjects and Methods] The subjects were randomly allocated into lumbar stabilization exercise group and a general physical therapy group. The program consisted of 30-min sessions conducted 3 days a week for 8 weeks. Pulmonary function was assessed based on lung ...

BACKGROUND The performance of spirometers is often evaluated under ideal conditions with computer-generated waveforms or in vivo testing with healthy subjects. Real-life conditions are less ideal because of comorbidities, age of the subjects, and a variety of air flow limitations. Evaluation of new spirometry equipment can also be performed under these less favorable conditions. The Spirospec i...

1. Forced exhalations performed from volumes below total lung capacity, so-called partial expiratory flow-volume curves, are suggested to be more sensitive in detecting airways bronchoconstriction than maximal expiratory flow-volume curves begun at total lung capacity. 2. In eight healthy men both maximal and partial expiratory flow-volume curves were measured where breath was held at total lun...

Lung mechanics and airway responsiveness to methacholine (MCh) were studied in seven volunteers before and after a 20-min intravenous infusion of saline. Data were compared with those of a time point-matched control study. The following parameters were measured: 1-s forced expiratory volume, forced vital capacity, flows at 40% of control forced vital capacity on maximal (Vm(40)) and partial (Vp...

Introduction: Adenotonsillar hypertrophy is a typical cause of surgery in children. Evaluation and identification of patients as potential candidates tonsillectomy is a primary concern for otolaryngologists. This study focuses on the results of pulmonary function tests (PFTs) after tonsillectomy in children. Materials and Methods: This cross-sectional study examined 50 patients suffering from t...

forty-five patients with chronic obstructive pulmonary disease were studied to compare the acute effects of ipratropium bromide (60 µg), salbutamol (300 µg) and placebo (3 puffs) on the forced expiratory volume in 1 sec (fev 1) and forced vital capacity (pvc). ipratropium bromide produced a significantly greater improvement than salbutamol in both fev1 and fvc at 15,60 and 180 minutes after dru...
