Does Sleep Differ Among Patients with Common Musculoskeletal Pain Disorders?
Summary of "Does Sleep Differ Among Patients with Common Musculoskeletal Pain Disorders?"
Most patients with chronic musculoskeletal pain report poor-quality sleep. The impact of chronic pain on sleep can be described as a vicious circle with mutual deleterious influences between pain and sleep-associated symptoms. It is difficult, however, to extract quantitative or consistent and specific sleep variables (eg, total sleep time, slow-wave sleep, sleep stage duration) that characterize the pain-related disruption of sleep. Comorbidity (eg, fatigue; depression; anxiety, sleep, movement, or breathing disorders) often confounds the reading and interpretation of sleep traces. Furthermore, many other methodologic issues complicate our ability to generalize findings (low external validity) to first-line medicine. Because sleep alterations in common musculoskeletal pain are neither specific nor pathognomonic, the aim is to provide a critical overview of the current understanding of pain and sleep interaction, discussing evidence-based and empiric knowledge that should be considered in further research and clinical applications.

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
Sleep Disorders, Intrinsic
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)
A sleep disorder of central nervous system origin characterized by prolonged nocturnal sleep and periods of daytime drowsiness. Affected individuals experience difficulty with awakening in the morning and may have associated sleep drunkenness, automatic behaviors, and memory disturbances. This condition differs from narcolepsy in that daytime sleep periods are longer, there is no association with CATAPLEXY, and the multiple sleep latency onset test does not record sleep-onset rapid eye movement sleep. (From Chokroverty, Sleep Disorders Medicine, 1994, pp319-20; Psychiatry Clin Neurosci 1998 Apr:52(2):125-129)
Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)
There have been proposals for REM to have a function of emotional memory consolidation, and also for REM sleep to be involved in the promotion of attachment behaviour. The hormones cortisol and oxytoc...
ABSTRACT: BACKGROUND: Difficulty sleeping is common among patients with fibromyalgia (FM); however, its impact on health-related quality of life (HRQoL) is not well understood. The aim of the current...
Sleep disturbances are widespread in schizophrenia, and one important concern is to determine the impact of this disruption on self-reported sleep quality and quality of life (QoL). Our aim was to eva...
PURPOSE: The extent and clinical relevance of the association between epilepsy and sleep apnea are not previously studied in Egypt. What we wanted to know was the frequency of sleep apnea in Egyptian...
The aim of this study is to characterize the time profile of the decongestant properties of xylometazoline and to investigate its effect on sleep, general well-being and smell/taste.
The purpose of this study is to examine the effects of (a) quetiapine XR and (b) mirtazapine on sleep when given as an antidepressant (monotherapy). We hypothesize that (a) quetiapine XR h...
The purpose of this study is to examine the consequences of chronic sleep restriction on nighttime sleep, daytime alertness, performance and memory functions, and metabolic and cardiovascu...
Objectives: To assess the efficacy of an intervention program targeted to the elderly with recent-onset disability of musculoskeletal origin (DIMS), and to perform its economic evaluation.
Current guidelines recommend endocrine treatment with aromatase inhibitors (AIs) in post-menopausal women with hormone receptor-positive breast cancer. Musculoskeletal symptoms are commonl...
