Active clinical trials for "Myofascial Pain Syndromes"

This study collects post-marketing safety and efficacy surveillance data in real world clinical use of pregabalin for its approved indications in Korea.

The study has two goals. The first goal of the study is to compare two methods of administering questions about pain and sleep interference. The two methods being compared are a telephone based system and an electronic hand held diary. The second goal of the study is to evaluate a daily diary to evaluate fatigue symptoms in patients with fibromyalgia.

Fibromyalgia Syndrome (FMS) is a chronic musculoskeletal disorder accompanied by diffuse body pain, increased fatigue and tenderness in specific anatomical regions, and sleep disturbance. The higher prevalence of FMS in women and the observation of it from young adulthood suggest the effect of sex hormones on the pathophysiology of this condition. Steroid hormones, especially estrogen, have effects on both the peripheral and central nervous system receptors (estrogen receptor-a [ERa] and estrogen receptor-b [ERb]), on the inflammatory process, and on central pain delivery. However, the mechanism of action of these hormonal effects is still unknown and is a matter of debate. The fact that fibromyalgia syndrome and migraine are more common in women of reproductive age and their incidence is higher than other populations suggests that these two diseases may have a common genetic basis. Previous studies have shown that ESR-1 594G> A (rs2228480), ESR-1 325C> G (rs2295190) polymorphisms significantly increase the risk of migraine occurrence. However, there are no studies investigating these polymorphisms in FMS. In this study, it was aimed to investigate whether there is a relationship between ESR-1 594G> A (rs2228480) and ESR-1 325C> G (rs2295190) polymorphisms and fibromyalgia disease.

The aim of the present study was to evaluate the association between ferritin levels and clinical parameters in patients with fibromyalgia syndrome.

Fibromyalgia affects 2 to 5% of adults in the general population. Patients describe a combination of symptoms centred around fatigue not induced by exercise and not relieved by rest. The diagnosis of fibromyalgia is self-perpetuating by the deconditioning, consequence of a reduced muscle mass due to inactivity and periods of prolonged rest. Thus, it seems fundamental to develop other non-drug approaches: among them, adapted physical activity is recommended by most learned societies because of a good level of evidence (Level 1, Grade A). The question remains, however, whether simple advice to resume physical activity is sufficient (routine care with medical assessment at 3 months) or whether a physical activity supervised inside and outside the hospital is not more relevant.

Myofascial pain dysfunction syndrome (MPDS) is the most common reason for pain and limited function of the masticatory system. The low-level laser therapy (LLLT) and occlusal splint therapy (OST) are therapeutic options for MPDS. This study aims to evaluate the effect of LLLT and OST on pain relief and mandibular movement improvement in patients with myofascial pain.

Therapy for fibromyalgia is a well discussed topic in literature, yet not thoroughly evidence-based. Several unicomponent therapies seem to be benificial. Whereas multicomponent and multidisciplinary therapy gains importance and revealing promising results, the investigators aim to combine two well-known therapies in a program for patients with fibromyalgia. From clinical experience, a high drop-out rate has been stated. All data will be explored to analyse explanatory factors.

Fibromyalgia (FM) is a world widely common syndrome, characterized by widespread pain, often accompanied by general fatigue, soreness, and abnormal sensations (like "pins and needles"). The reasons and the mechanisms (pathogenesis) of FM are still poorly understood. Efficacious therapies cannot be developed without understanding the pathophysiological mechanisms of the disease or syndrome. FM patients suffer from pain and sense of weakness and fatigue in the muscles, and often report difficulty in relaxing their muscles. So far, the studies on muscle activation in fibromyalgia (mostly using surface electromyography) have shown some unusual functioning, a kind of overuse, but the results have been somewhat contradictory. FM symptoms share some features with small fibre neuropathy, which is a disease or abnormality of small nerve fibres with a diverse aetiology. Recently, several research groups have shown (studying both the electrical function of superficial nerves and nerve endings of skin samples) that up to 50% of the FM patients with severe symptoms have small fibre neuropathy: their small nerves do not function properly and small nerve fibre density in their skin is reduced. However, as this phenomenon is common but not a rule, it might be rather a consequence of some underlying mechanisms of the syndrome, creating even more symptoms. The aim is to investigate whether there would exist metabolic changes in FM patients that would create pain and lead to functional changes and damage in small nerve fibres. The investigators also aim to explore the muscle function particularly in distressed situations and at rest. The hypothesis is that a towards-overuse-altered function would create unfavourable metabolic changes. Third, the aim is to investigate some psychological factors (such as tendency to get anxious or distressed) to find out, if there is any association between them and muscle function. The FM patients as well as healthy control subjects will be recruited at Helsinki University Hospital Pain Clinic and from primary care at Vantaa Health Care Centre. The voluntary test subjects will attend A muscle function examination of 30 minutes with electromyography using surface electrodes, including mentally distressing tasks and relaxing periods. At the same session, the subject will reply to some questionnaires regarding their symptoms and measuring some psychological factors. Actual pain level will be assessed. A glucose tolerance test, with other blood samples A bicycle ergometer exercise test of 20 - 30 minutes, with both physiological and chemical (blood samples) recordings. Actual pain level will be assessed as well. At this stage, 40 patients and 20 healthy control subjects will be recruited.

This study will evaluate respiratory function in people with fibromyalgia and whether or not breathing patterns in this patient group can be explained by stress, emotional or biomechanical variables. In addition, examine the relationship between physical ability and lactate values.

This study evaluates the feasibility of a behavioral intervention designed to replace sedentary behavior with light physical activity in veterans with Fibromyalgia. The study will also evaluate the acceptability of the intervention among veterans and intervention effects on pain and physical function.
