OBJECTIVE To determine whether disrupted slow wave sleep (SWS) would evoke musculoskeletal pain, fatigue, and an alpha electroencephalograph (EEG) sleep pattern. We selectively deprived 12 healthy, middle aged, sedentary women without muscle discomfort of SWS for 3 consecutive nights. Effects were assessed for the following measures: polysomnographic sleep,(More)
The purpose of this investigation was to compare self-reported sleep quality and psychological distress, as well as somnographic sleep and physiological stress arousal, in women recruited from the community with self-reported medically diagnosed fibromyalgia (FM) to women without somatic symptoms. Eleven midlife women with FM, when compared to 11(More)
OBJECTIVE To compare sleep disturbances and neurobehavioral function in children with juvenile idiopathic arthritis (JIA) to age- and sex-matched control children. METHODS Children (n = 116) ages 6-11 years with (n = 70) and without (n = 46) JIA and their parents participated. Parents completed questionnaires on sleep habits, sleep behavior, and school(More)
Sleep hygiene education is a basic component of behavioral treatment for chronic insomnia, yet the actual sleep hygiene practices of people with insomnia have not been well documented. In this descriptive secondary analysis, midlife women ages 41-55 years with either chronic insomnia (n = 92) or good sleep (n = 29) kept diaries of sleep perceptions and(More)
OBJECTIVES Chronic fatigue syndrome (CFS) has been associated with altered amounts of slow wave sleep, which could reflect reduced delta electroencephalograph (EEG) activity and impaired sleep regulation. To evaluate this hypothesis, we examined the response to a sleep regulatory challenge in CFS. DESIGN The first of 3 consecutive nights of study served(More)
In women with fibromyalgia (FM), central nervous system (CNS) dysfunction in pain, mood, and sleep processes could be associated with changes in immune system indicators. The primary purpose of this study was to compare pain, psychological variables, subjective and objective sleep quality, lymphocyte phenotypes and activation markers, and natural killer(More)
The purpose of this study was to compare arousal levels and stress response across menstrual cycle phases in women with three perimenstrual symptom patterns. Women with low symptom severity (LS, N = 28), were compared with those with a premenstrual syndrome (PMS, N = 15) and premenstrual magnification (PMM, N = 19) pattern across postmenses and premenses(More)
Sleep deprivation alters thermoregulatory responses. We used control of skin temperature to produce mild thermal challenge, both cool (32 degrees C) and warm (38 degrees C), and recorded esophageal and rectal temperatures, sweat rate and forearm blood flow in six healthy young women at rest. We discovered that after one night of sleep deprivation (1) both(More)
OBJECTIVE To compare polysomnography (PSG) and self-reported sleep, symptoms (pain and fatigue), and anxiety between children with active and inactive juvenile rheumatoid arthritis (JRA) and examine relations among sleep, symptoms, and anxiety. METHODS Two consecutive nights of PSG, self-reported sleep, and symptoms were obtained in 70 children 6-11 years(More)
Patients with irritable bowel syndrome (IBS) commonly report sleep disturbances. This study examined self-report (Pittsburgh Sleep Quality Inventory) sleep quality and polysomnography (PSG) sleep variables in 18 women with mild-to-moderate IBS, 18 with severe IBS and 38 with age- and gender-matched controls. All women were studied on two consecutive nights(More)
