Interviews on the occurrence of Myofascial Pain-Dysfunction (MPD) Syndrome were held with a group consisting of 246 individuals 25 years of age. Every fifth interviewee said she/he had experienced clicking/crepitation from the TMJs. Five percent had felt pain when opening the mouth wide and 3% while chewing, yawning or talking. These frequencies of symptoms were much like those found in a probability sample of the total adult population in Norway and a probability sample of elderly Norweigians. In the present study, 28% said they had some or much headache recently. These symptoms varied with background characteristics, especially with sex. There was also a relationship between headache and MPD-symptoms. By combining the effect of the variables sex and headache upon the frequency of reported clicking/crepitation, it was tripled.

Primary fibromyalgia syndrome (PFS) is a form of nonarticular rheumatism characterized by muscular pain and stiffness, commonly located in the neck-, shoulder-, back-, and pelvic regions. The most common finding in patients with mandibular dysfunction (MD) is pain or tenderness of the masticatory muscles, but tender and painful neck and shoulder muscles are also often found in relation to jaw muscle affection. Complaints presented by patients suffering from musculoskeletal conditions may overlap one another. Indeed, there may be some common causative factors for these complaints. To test the hypothesis that some complaints by PFS patients could be explained by mandibular dysfunction, we have investigated the subjective symptoms and the clinical state of the stomatognathic system in eight patients suffering from PFS. According to the Helkimo anamnestic dysfunction index, six patients were classified as having severe signs of MD. The Helkimo clinical dysfunction index revealed severe or moderate dysfunction in all patients. Recurrent headaches was reported by half of the patients. In conclusion, the present study shows that PFS patients also may suffer from mandibular dysfunction. Thus, an examination of the function of the stomatognathic system would be an important part in the investigation to elucidate possible etiological factors behind the reported complaints by PFS patients. PFS may also be of etiological importance for mandibular dysfunction.

We tested the current criteria for fibromyalgia. Pain tolerance was measured at tender point and control point sites using a pressure algometer, and responses to 6 standard psychological self-reports were obtained from 125 patients with generalized nonarticular rheumatism, rheumatoid arthritis, or osteoarthritis. Among patients with generalized nonarticular rheumatism, published symptom criteria for fibromyalgia did not correlate significantly with the number of tender points. Only lower generalized pressure point pain tolerance distinguished fibromyalgia from other generalized nonarticular rheumatism. Generalized nonarticular rheumatism mean scores were much higher than controls on tests measuring the tendency to report physical symptoms, including headaches and functional bowel syndrome. It is probable that patients with fibromyalgia do not differ in any important physical or psychological respect from other patients with generalized nonarticular rheumatism except for the presence of tender points. However, the presence of tender points is merely a reflection of the patient's general pressure pain sensitivity and is not indicative of any special localized pathological phenomenon. The concept of fibromyalgia as an entity separate from the rest of generalized nonarticular rheumatism may be an artifact of a physician's approach to the patient. Most patients with generalized nonarticular rheumatism demonstrate an abnormally high frequency of reporting manifold disagreeable symptoms and probably come to the attention of many medical disciplines.

Primary fibromyalgia syndrome (PFS) is a common form of nonarticular rheumatism with diffuse musculoskeletal aching and stiffness at multiple sites and tender points at characteristic locations. Nonmusculoskeletal "systemic" symptoms, eg, fatigue, poor sleep, irritable bowel symptoms, and chronic headaches, are also common. Although PFS is similar to myofascial pain syndrome (MPS) in that both conditions cause muscle pain and tenderness, important differences exist. Unlike PFS, muscle pain in MPS is usually local or regional, accompanied by trigger points. Unlike tender points, trigger points produce a referral pain pattern specific to each muscle. Moreover, "systemic" features of PFS are usually absent in MPS. Common and important pathologic changes in muscle in PFS are moth-eaten appearance of Type I fiber by histochemistry, and myofibrillar lysis with glycogen and mitochondria deposition by electron microscopy; inflammatory changes are absent by light microscopy. Recent investigations have shown that PFS is a characteristic clinical entity. Further controlled studies are, however, essential to establish the pathologic changes in tender muscles in PFS.

Myofascial pain-dysfunction (MPD) syndrome is a muscle-contraction headache-like pain of the face. In the past this has also been called temporomandibular joint syndrome. This syndrome is thought to be, in part, a stress-related pain. This paper discusses and evaluates the following topics: (1) patient characteristics, (2) etiological hypotheses, (3) experimental models of the syndrome, (4) psychological characteristics of the patients, (5) psychophysiological characteristics of the patients, and (6) relaxation therapies. Future research is also discussed.

Idiopathic edema is usually orthostatic. It is most evident in the feet or abdomen after prolonged standing or sitting and in the fingers and eyelids after recumbency overnight. It occurs almost exclusively in post-pubertal women and is associated with discomfort in the areas of fluid accumulation (including symptoms of the carpal tunnel syndrome, nonarticular rheumatism, and headaches, sometimes with pseudotumor cerebri), and weight gain with excessive increments from morning to evening. The pathogenesis, diagnosis, and treatment of idiopathic edema are discussed.

Myofascial pain, referred from hyperalgesic trigger points located in skeletal muscle and its associated fascia, is a common cause of persistent regional pain. Clinical and experimental literature on manifestations, pathophysiology, and management of pain from myofascial trigger points is reviewed with priority given to how pain referred from trigger points generates, triggers, and maintains headaches--especially chronic and recurrent ones. Because treating myofascial problems may be the only way to offer complete relief from certain types of headache, clinicians must learn to diagnose and manage trigger points in neck, shoulder, and head muscles.

Fibromyalgia (FM), also known as fibromyalgia syndrome (FMS) and fibrositis, is a common form of nonarticular rheumatism that is associated with chronic generalized musculoskeletal pain, fatigue, and a long list of other complaints. Some have criticized the classification of FM as a distinct medical entity, but existing data suggest that individuals meeting the case definition for FM are clinically somewhat distinct from those with chronic widespread pain who do not meet the full FM definition. Clinic studies have found FM to be common in countries worldwide; these include studies in specialty and general clinics. The same is true of general population studies, which show the prevalence of FM to be between 0.5% and 5%. Knowledge about risk factors for FM is limited. Females are at greater risk, and risk appears to increase through middle age, then decline. Although some authors claim that an epidemic of FM has been fueled by an over-generous Western compensation system, there are no data that demonstrate an increasing incidence or prevalence of FM; moreover, existing data refute any association between FM prevalence and compensation. Claims that the FM label itself causes illness behavior and increased dependence on the medical system also are not supported by existing research. This article reviews the classification, epidemiology, and natural history of FM.

Myofascial pain is frequently overlooked in dealing with headache pain. Myofascial pain is defined as pain and/or autonomic phenomena referred from active trigger points, with associated dysfunction. The trigger point is a focus of hyperirritability in the muscle, that when compressed, is locally tender, and if sensitized, gives rise to referred pain and tenderness. The therapy for myofascial pain requires enhancing central inhibition through pharmacology or behavioral techniques and simultaneously reducing peripheral inputs through physical therapies including exercises and trigger point-specific therapy.

Myofascial pain is a common cause of regional chronic pain. Myofascial trigger points can refer pain to the head and face in the cervical region, thus contributing to cervicogenic headache. When identified properly, cervical myofascial pain is a treatable component of headache management. This article reviews current literature on the pathophysiology, diagnosis, and management of cervical myofascial pain.
