abstract background: sleep disorders like snoring, mouth breathing, and insomnia are frequent in pregnancy and studies have shown that poor sleep is linked to obstetric complications. muscle relaxation technique is an effective method used for improving sleep quality. the purpose of this study was to determine the effect of muscle relaxation technique on fetal outcomes in complicated pregnancie...

The existence of normal sleep in patients in a vegetative state is still a matter of debate. Previous electrophysiological sleep studies in patients with disorders of consciousness did not differentiate patients in a vegetative state from patients in a minimally conscious state. Using high-density electroencephalographic sleep recordings, 11 patients with disorders of consciousness (six in a mi...

Obesity is a primary risk factor for the development of obstructive sleep apnea in humans, but the impact of obesity on central sleep apnea is less clear. Given the comorbidities associated with obesity in humans, we developed techniques for long-term recording of diaphragmatic EMG activity and polysomnography in obese mice to assess breathing patterns during sleep and to determine the effect o...

BACKGROUND Night-to-night variability in sleep of children with attention deficit hyperactivity disorder (ADHD) may be a mediator of behavioral phenotype. We examined the potential association between alertness, sleep, and eating behaviors in children with ADHD and comorbid problems. METHODS Sleep was monitored by actigraphy for 7 days. Questionnaires were used to assess sleep complaints, hab...

Common medical conditions are often associated with sleep abnormalities. Patients with medical disorders often suffer from poor sleep quality compared to healthy individuals, which in turn may worsen the symptoms of the disorder. Accurate detection of sleep/wake patterns is important in developing personalized digital markers, which can be used for objective measurements and efficient disease m...

The comparative effects of sleep patterns and rates of cyclic alternating patterns (CAP rate) in a high quality innerspring mattress were compared to those on a unique foam support mattress in 10 normal subjects. Results showed no differences in sleep stages, number of wakes, or total sleep time between the two conditions. CAP rates were significantly reduced on the foam surface. CAP rate was s...

Shift work can be attributed to some of social and health problems in working community. In this study an attempt was made to study the sleep and wakefulness patterns in nurses engaged in rotational and non-rotational shift work in a hospital through sleep charts. It was observed that non-rotational workers enjoyed more frequent and longer naps and had less disturbances in their sleep patterns ...

OBJECTIVES We studied sleep in a rural population in Madagascar to (i) characterize sleep in an equatorial small-scale agricultural population without electricity, (ii) assess whether sleep is linked to noise levels in a dense population, and (iii) examine the effects of experimentally introduced artificial light on sleep timing. METHODS Using actigraphy, sleep-wake patterns were analyzed for...

From a behavioral as well as neurobiological point of view, sleep and consciousness are intimately connected. A better understanding of sleep cycles and sleep architecture of patients suffering from disorders of consciousness (DOC) might therefore improve the clinical care for these patients as well as our understanding of the neural correlations of consciousness. Defining sleep in severely bra...

OBJECTIVE To investigate abnormal breathing patterns during sleep in prepubertal children using nonstandard polysomnographic patterns in association with an apnea-hypopnea scoring technique. PATIENTS AND METHODS Study participants included 400 children with suspected sleep-related breathing disorders and 60 control children. We analyzed clinical signs and symptoms at entry into the study and ...
