STUDY OBJECTIVES To compare anthropomorphic, nocturnal polysomnographic (PSG), and multiple sleep latency test (MSLT) data between positional (PP) and nonpositional (NPP) obstructive sleep apnea (OSA) patients. DESIGN This is a retrospective analysis of anthropomorphic, PSG, and MSLT data of a large group of OSA patients who underwent a complete PSG(More)
STUDY OBJECTIVES To evaluate the effect of body position on REM-related obstructive sleep apnea (OSA) patients. DESIGN Retrospective analysis. PATIENTS 100 consecutive adult OSA patients (apnea-hypopnea index [AHI] > or = 5) who had > or = 10 min of REM sleep in both supine and lateral postures. REM-related OSA was defined by previously used criteria(More)
STUDY DESIGN The psychometric properties and clinical use of a battery of physical performance measures were tested on 44 patients with low back pain and 48 healthy, pain-free control subjects. OBJECTIVES Reliability, validity, and clinical use of nine physical performance measures were evaluated. SUMMARY OF BACKGROUND DATA Although physical performance(More)
Obstructive sleep apnea (OSA), is a common clinical condition affecting at least 2-4% of the adult population. Hypertension is found in about half of all OSA patients, and about one-third of all patients with essential hypertension have OSA. There is growing evidence that successful treatment of OSA can reduce systemic blood pressure (BP). Body position(More)
STUDY OBJECTIVES To evaluate the impact of sleep position on optimal nasal continuous positive airway pressure (nCPAP [op-nCPAP]) in obstructive sleep apnea (OSA) patients and to investigate how rapid eye movements (REM) and Non-REM (NREM) sleep, body mass index (BMI), respiratory disturbance index (RDI), and age are related to this effect. DESIGN(More)
The aim of this study was to evaluate demographic and polysomnographic characteristics of positional (PPJ) and non-positional obstructive (NPP) sleep apnea (OSA) patients in 2077 OSA patients diagnosed in our Sleep Disorders Unit during a period of 10 years. An OSA patient is defined as positional if he has twice as many or more breathing abnormalities(More)
STUDY OBJECTIVES To determine whether sleep-related erections occur in vegetative state and if so, to investigate their relationship with rapid eye movement (REM) sleep. DESIGN N/A. SETTING Major rehabilitation hospital. PATIENTS Nine male patients in vegetative state aged 17-40 years. INTERVENTIONS Continuous 24-hour polysomnographic recordings(More)
BACKGROUND Cheyne-Stokes Respiration (CSR) is a common finding in Chronic Heart Failure and Stroke patients. The body position effect during sleep on obstructive breathing abnormalities is well known. However, the effect of body position during sleep on breathing abnormalities of central type like CSR has not been well documented. MATERIAL/METHODS Six(More)
Obstructive sleep apnea (OSA) occurs in about 10% of the middle-aged population but in about 30% of the hypertensive population of the same age. About 20% of the middle-aged population has hypertension but about 50% of patients with OSA have hypertension. Despite this close relationship between these two entities, previous attempts to determine whether the(More)
The hypothesis was tested that unilateral dopamine deficiency leading to the contralateral extrapyramidal syndrome (hemi-parkinsonism) would cause distinctly asymmetric EEG sleep patterns. In 7 hemi-Parkinson's patients 2 nights of sleep were monitored along with pre-sleep waking periods. No medication was given prior to the first night. The second night(More)
