Fibromyalgia syndrome (FMS) is characterized by the presence of widespread pain, chronic fatigue and typical sleep disturbances. The purpose of the current study is to investigate the nature of sleep disturbance in FMS, using a novel technology. Peripheral arterial tonometry is a method by which peripheral arterial tone is measured non - invasively using in an ambulatory setup during sleep. The information collected reflects autonomic nervous system function and respiratory changes during sleep. We intend to utilize this technique in order to improve our understanding of the interrupted patterns of sleep in FMS and as a possible biomarker which may be used in the future to follow up FMS patients and their response to treatment.
Fibromyalgia Syndrome (FMS) is a clinical entity characterized by the presence of chronic, widespread pain and tenderness throughout the musculoskeletal system. FMS is considered to be a prototype of central pan syndromes, conditions in which augmentation of pain processing by the central nervous system in a major feature (1;2). As such, FMS overlaps with a number of similar "functional" disorders, including TMJD, IBS, Interstitial cystitis, Gulf war syndrome, chronic fatigue syndrome etc (3-5).
A major clinical feature of FMS is the presence of chronic fatigue, which is typically accompanied by a severely disrupted sleep pattern. Difficulty falling asleep, frequent awakening and non-refreshing sleep are all features classically reported by FMS patients. In addition, a number of classic sleep disturbances have been identified among FMS patients such as alpha - wave intrusion, disrupting normal stage IV sleep, as well as nocturnal falls in oxygen saturation (6). Notably, disturbed sleep may contribute not only to chronic fatigue, but also to enhanced pain processing as well as depression in FMS patients (7). Thus, pain inhibitory functions of the CNS, such as the process of Diffuse Noxious Inhibitory Control (DNIC) appear to be impaired in by sleep disruption (8).
Considerable interest has focused on the role of sleep apnea in FMS, as a possible factor contributing to fatigue and pain. Overt obstructive sleep apnea has been diagnosed in some patients (9) while more subtle disruptions of upper airway dynamics, such as increased upper airway pressure, not leading to total airway collapse, has been detected in many patients (10). Other researchers however have challenged the association of FMS with sleep apnea (11).
Autonomic dysfunction is another important clinical manifestation of FMS with common symptoms including presyncope / syncope, palpitations on standing and dizziness (12). Postural Orthostatic Tachycardia Syndrome (POTS) is another autonomic disorder which clinically overlaps with FMS (13).
Traditional polysomnography is a time-consuming and costly procedure, and hence, relatively few FMS patients are formally evaluated for sleep disorders in clinical practice.
The Watch-PATTM100 is a non-invasive device, which utilizes peripheral arterial tone (PAT), reflecting changes in autonomic nervous system function, as a marker for identifying and documenting respiratory disturbances during sleep. The PAT signal is acquired through a non-invasive probe attached to the finger during the sleep. Parameters measured include oxygen saturation, heart rate, sleep and wake states, REM and non-REM sleep.
The purpose of the current study is to use Peripheral Arterial Tonometry (PAT) in order to compare both disturbed sleep breathing and autonomic dysfunction in fibromyalgia patients and healthy controls.

A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, HEADACHES, and occasionally DEPRESSION. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (FATIGUE SYNDROME, CHRONIC). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (From Adams et al., Principles of Neurology, 6th ed, p1494-95)
A gamma-aminobutyric acid (GABA) derivative that functions as a CALCIUM CHANNEL BLOCKER and is used as an ANTICONVULSANT as well as an ANTI-ANXIETY AGENT. It is also used as an ANALGESIC in the treatment of NEUROPATHIC PAIN and FIBROMYALGIA.
A thiophene derivative and selective NEUROTRANSMITTER UPTAKE INHIBITOR for SEROTONIN and NORADRENALINE (SNRI). It is an ANTIDEPRESSIVE AGENT and ANXIOLYTIC, and is also used for the treatment of pain in patients with DIABETES MELLITUS and FIBROMYALGIA.
A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social, or personal activities. Minor alterations of immune, neuroendocrine, and autonomic function may be associated with this syndrome. There is also considerable overlap between this condition and FIBROMYALGIA.
