Active clinical trials for "Fibromyalgia"

The objective of this protocol is to evaluate if Dextromethorphan (DXM) reduces Fibromyalgia (FM) pain. DXM is a drug found in several over-the-counter products, including cough suppressants. The drug may reduce FM pain by suppressing inflammation in the central nervous system. The investigators will be observing the effects of DXM on daily self-reported pain measures in people with FM. If DXM reduces FM pain, it will provide important information about the nature of FM pathophysiology.

Researchers are evaluating if cognitive behavioral therapy for insomnia delivered over the internet will help with fibromyalgia symptoms.

Pain is a powerful motivator of behavior and it is more than the perception of nociceptive input. It is a complex experience that comprises different components: sensory discriminative, emotional-motivational and cognitive components. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain components. Such a negative hedonic shift is mirrored in a high comorbidity of chronic pain with affective disorders like depression and anxiety. However, the neurobiological mechanisms underlying such a negative hedonic shift i remain elusive. Animal work suggests an involvement of neuroinflammation, caused by chronic pain, which in turn is related to impaired release of the neurotransmitter dopamine. In line with this observation, impaired dopamine functioning has been described in chronic pain. Importantly, dopamine acts also as a neuromodulator, regulating functional connectivity between brain regions. Therefore, dysfunctional dopamine in chronic pain, possibly caused by neuroinflammation, might lead to altered blood oxygen level dependent (BOLD) response and functional connectivity. Correspondingly, altered functional connectivity in fronto-striatal brain networks has been shown to be predictive of transition from subacute to chronic pain. The aim of this study is to investigate the psychobiological mechanisms underlying the negative hedonic shift in chronic pain with a focus on the role of dopamine in functional connectivity of fronto-striatal brain networks, BOLD response of frontostriatal regions and their relation to heightened emotional-motivational pain processing.

The major goal of this study is to determine if the innate immune response is dysregulated in people with fibromyalgia, compared to healthy controls. Magnetic resonance spectroscopy will be used to measure changes in the brain's metabolic profile following an experimental immune stimulus, to test whether individuals with fibromyalgia show a heightened immune response in the brain. The ultimate goal of this research is to better understand the role of brain inflammation in the pathophysiology of chronic pain and fatigue, which will guide the development of more effective therapies for these conditions.

Veterans who have responded well to Battlefield Acupuncture (BFA), a form of auricular acupuncture, in routine clinical practice will be invited to receive education to insert the needles themselves at home. A 3D-printed wearable prosthetic will also be explored as a means to facilitate needle placement. Primary end-points will include whether adverse events occur over a six-month period and whether the aforementioned prosthesis significantly facilitates needle placement in terms of subjective ease of administration.

Myofascial pain syndrome (MPS) is a common problem in the general population. MPS should not be a local/peripheral painful syndrome and considered to be a syndrome of central sensitivity. We aimed to investigate the effect of pregabalin in patients with MPS in this study

Specific Aims: To identify phenotypes of patients with fibromyalgia according to symptom clusters and to compare differences in quality of life (QOL) among different phenotypes. To examine the effects of technology-assisted and tailored health coaching in comparison to telephone support on health status, QOL, pain catastrophizing, and self-efficacy in patients with fibromyalgia. Methods: For Aims 1, the investigators will conduct a cross-sectional study and enroll 300 patients with fibromyalgia. Symptoms will be assessed using the Numerical Rating Scale, Athens Insomnia Scale, Functional Assessment of Cancer Therapy cognition scale, Beck Depression Index-II, Beck Anxiety Index, and Fatigue Severity Scale. The World Health Organization Quality of Life-Brief Form (WHOQOL-BREF) questionnaire will be used to assess participants' overall QOL. Hierarchical cluster analyses will be used to identify fibromyalgia phenotypes according to pain, physical, and psychological variables. A series of multivariate analysis of variance analyses will be used to compare the differences in WHOQOL-BREF scores among those phenotypes. For Aims 2, the investigators conduct an assessor-blind, parallel-group, randomized controlled trial and enroll 110 participants with fibromyalgia. Participants will be randomized to a health coaching group and a control group. The tailored, interactive health-coaching program will be delivered via mobile applications during a 10-week training period. The control group will receive standard education materials and weekly telephone support. The primary outcomes are the revised Fibromyalgia Impact Questionnaire and WHOQOL-BREF scores; the secondary outcomes are pain catastrophizing score and self-efficacy, which will be examined at baseline, post-training, and the 3th month follow-up. Data will be analyzed according to the intention-to-treat principle. To determine the effectiveness of health coaching on primary and secondary outcomes, differences in outcome variables will be analyzed with mixed-effects linear regression models. The between-group differences at the two posttests examined using a mixed-model will include group x time interaction. The investigators will adjust for the baseline score on the outcome variable and for demographics and comorbidities that differ significantly between the intervention and control groups at baseline.

In order to investigate the therapeutic effect of acupuncture on chronic neck myofacial pain syndrome, the investigaotrs designed a pilot study of a single-blind randomized controlled trial. A total of 34 chronic neck myofacial pain syndrome patients were selected from Department of Neurology of Nantou Hospital, Department of Health. The age ranged from 18 to 85, and all subjects were full informed consent and volunteers. They were divided into two groups of 17 subjects randomly as follows: acupuncture group, acupuncture stainless needles were inserted into bilateral Fenhchi, Jianliao and Houxi acupoints, respectively. The acupuncture needles then were manual twist and de Qi, and remain for 20 min; sham acupuncture group, the methods were identical the acupuncture group, but acupuncture stainless needles were inserted into subcutaneous tissue only. All the subjects were treated with acupuncture two times per week and continuously three weeks, i.e. Six times acupuncture treatment. The therapeutic effect of acupuncture was assessed before and finishing six times acupuncture treatment, and four weeks and twelve weeks after stopping acupuncture, respectively. The index of acupuncture therapeutic effect was according to the range of motion (ROM) of the cervical spine, the intensity of pain (Short-Form McGill Pain Questionnaire; SF-MPQ) and quality of life (SF-36). The investigators expect acupuncture apply to bilateral Fenhchi, Jianliao and Houxi acupoints may relief the pain and motion of chronic neck facial pain syndrome patient, and also improves the life quality.

This Phase 1 study will assess the effects of esreboxetine on the heart. In particular the effects on a specific electrocardiogram (ECG) measurement called QTc will be measured.

The purpose of this study is to explore how pregabalin works in patients with fibromyalgia by evaluating brain imaging signals. To find out whether fMRI (functional magnetic resonance imaging) is an efficient way to show whether new pain medications are effective in treating fibromyalgia.
