Active clinical trials for "Myofascial Pain Syndromes"

Suffering a traumatic event is a potential risk factor for developing Posttraumatic Stress Disorder (PTSD) with or without comorbidities with other pathologies that can become chronic with time, including fibromyalgia. Different study results show the existence of an association between living traumatic events and developing fibromyalgia. However, studies in the field have not evaluated thoroughly the nature of traumatic events, the subsequent development of PTSD and the degree to which it can cause an impairment. These results will allow us increase the knowledge about the effects of comorbidity between both medical conditions, get to know in depth the type of traumatic events that female patients with FM suffer, and express the importance of the implementation of a therapeutic approach which takes into account the existing psychological symptoms in addition to the main principal pathology.

The primary aim of this study is to determine if osteopathic manipulative treatment is as effective to traditional lidocaine injection technique in treating myofascial trigger points in regard to post intervention pain intensity and quality of life.

Rheumatoid arthritis is a chronic, autoimmune, systemic inflammatory disease with a prevalence of approximately 1%. With a lifetime development rate of 3.6%, rheumatoid arthritis is seen 1.7% more in women than in men. Although there are no diagnostic criteria for rheumatoid arthritis, ACR / EULAR 2010 classification criteria are frequently used in diagnosis. Symptom duration, number of swollen joints, acute phase reactants and serology are used in these criteria. Fibromyalgia syndrome is characterized by chronic widespread pain, fatigue, exercise disorders and cognitive impairment. Although the prevalence of fibromyalgia syndrome in the general population is between 2-4%, it is one of the most common conditions encountered by rheumatologists. A treat to target strategy is recommended in rheumatoid arthritis disease management. This approach suggests close monitoring of disease activity and treatment change in cases where the goal is not achieved. The prevalence of fibromyalgia in rheumatoid arthritis patients was found to be 5-52% in meta-analyzes due to the heterogeneity of fibromyalgia criteria used in studies. This study, it was aimed to evaluate the effect of secondary fibromyalgia syndrome, which is frequently found in rheumatoid arthritis and characterized by symptoms such as fatigue and widespread pain, on rheumatoid arthritis disease activation and patients' quality of life.

This study's aim was to determine the effect of music therapy on symptoms and functions in patients with fibromyalgia syndrome (FMS).

Studies with quantitative electroencephalogram (qEEG) in people with fibromyalgia showed the existence of distinct patterns of brain electrical activity when compared to healthy individuals. Such dysfunctional patterns may be correlated to clinical symptoms of the syndrome as chronic pain and emotional disorders (depression and anxiety). As chronic pain can be considered a multidimensional symptom, its evaluation should consider beyond others, two main dimensions: the sensitive-discriminative dimension and the affective-motivational dimension. Previous studies have been describing distinct brain areas as neural substrates for processing such dimensions of pain. Thus, the identification of electrophysiological biomarkers (i.e., as qEEG measures) allowing to perform an evaluation between dysfunctional patterns of brain electrical activity and different dimensions of pain seems to be a promising path in the search for a better understanding of the syndrome as well as for more individualized and effective therapeutic approaches. Our objective was to investigate whether dysfunctional patterns of brain electrical activity in frontal and central areas of people with fibromyalgia are differently related to dimensions of pain (sensory-discriminative and affective-motivational) and to emotional disorders (depression and anxiety).

A cohort of fibromyalgia (FM) patients (n =90) and healthy controls (HC) (n= 93) was recruited to investigate the associations between human IgG binding to satellite glia cells (SGC) from dorsal root ganglia (DRG) and pathophysiological mechanisms. The study is based on previously identified mechanisms resulting from injecting human IgG antibodies from FM patients, but not HC, in mice (Goebel et al. J Clin Invest. 2021;131(13):e144201). Subjects have been carefully phenotyped using validated questionnaires and quantitative sensory testing (QST) was applied to determine pain sensitivity. A blood sample was taken to quantify anti-SGC IgG, as well as proteins, lipids and metabolites. Skin biopsies were taken to analyze changes in skin innervation (IENFD) and immune cell activation. Magnetic resonance spectroscopy (MRS) and functional magnetic resonance imaging (fMRI) was performed (n=122) to investigate central nervous system pain related mechanisms. Insular glutamate levels, as well as the levels of other brain metabolites will be determined (MRS) and related to symptom severity and anti-SGC IgG levels. Resting state as well as pain related cerebral activation (BOLD) during standardized evoked pain stimuli will be characterized (fMRI) and related to the MRS findings and to anti-SGC IgG levels.

Fibromyalgia syndrome (FS) is characterized by widespread pain and affect 0.5 to 5 % of the general population, with a higher prevalence in women. Recognized as disease by World Health Organization since 1992, FS concern 1.2 to 2 million of French people and his etiology need to be clarified. This affection is characterized by a higher sensitivity to nociceptive stimulus, articular and muscular pain and associated to: fatigue, headache, sleep disorders, depression and irritated bowel syndrome. The presentation of this symptoms varied according to the patient with a heterogeneity of the clinical, physical, social and psychologic conditions and of the therapeutic responses. Faced to the heterogeneity of FS, various hypotheses about the development mechanisms exist. Central sensitization could be one of the key mechanisms of FS, it is described as a loss of the natural balance between the transmission of a painful stimulus to the central nervous system and pain-inhibiting mechanisms, which results in permanent or chronic pain. Moreover, work on the familial character of FS suggests that a genetic component may be involved in its development, but the identification of a genetic determinant is difficult given the multifactorial nature and complexity of FS. The objective of this study is to characterize the predispositions of central sensitization and genetics in patients with FS compared to a control group, matched in age, sex and menopausal status.

In this pilot study we propose to gather preliminary data on whether transdermal magnesium chloride can improve quality of life in patients with fibromyalgia. Forty women with fibromyalgia will be enrolled in this study. Participants will be asked to apply a topical solution of magnesium chloride on their extremities 3 times daily for 28 consecutive days. Three questionnaires measuring quality of life will be administered at baseline, at 2 weeks, and at 4 weeks (end of study).

Depression and unrefreshed sleep are frequent in patients with fibromyalgia. Agomelatine is a new antidepressant with sleep-promoting properties. The objective of this study include the assessment of agomelatine therapy in patients with depression and fibromyalgia both on the severity of depressive symptomatology and sleep quality.

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