A Systematic Overview of Reviews for Complementary and Alternative Therapies in the Treatment of the Fibromyalgia Syndrome
Objectives. This systematic overview of reviews aimed to summarize evidence and methodological quality from systematic reviews of complementary and alternative medicine (CAM) for the fibromyalgia syndrome (FMS). Methods. The PubMed/MEDLINE, Cochrane Library, and Scopus databases were screened from their inception to Sept 2013 to identify systematic reviews and meta-analyses of CAM interventions for FMS. Methodological quality of reviews was rated using the AMSTAR instrument. Results. Altogether 25 systematic reviews were found; they investigated the evidence of CAM in general, exercised-based CAM therapies, manipulative therapies, Mind/Body therapies, acupuncture, hydrotherapy, phytotherapy, and homeopathy. Methodological quality of reviews ranged from lowest to highest possible quality. Consistently positive results were found for tai chi, yoga, meditation and mindfulness-based interventions, hypnosis or guided imagery, electromyogram (EMG) biofeedback, and balneotherapy/hydrotherapy. Inconsistent results concerned qigong, acupuncture, chiropractic interventions, electroencephalogram (EEG) biofeedback, and nutritional supplements. Inconclusive results were found for homeopathy and phytotherapy. Major methodological flaws included missing details on data extraction process, included or excluded studies, study details, and adaption of conclusions based on quality assessment. Conclusions. Despite a growing body of scientific evidence of CAM therapies for the management of FMS systematic reviews still show methodological flaws limiting definite conclusions about their efficacy and safety.

Objectives . Biofeedback (BFB) is an established intervention in the rehabilitation of headache and other pain disorders. Little is known about this treatment option for fibromyalgia syndrome (FMS). The aim of the present review is to integrate and critically evaluate the evidence regarding the efficacy of biofeedback for FMS. Methods . We conducted a literature search using Pubmed, clinicaltrials.gov (National Institute of Health), Cochrane Central Register of Controlled Trials, PsycINFO, SCOPUS, and manual searches. The effect size estimates were calculated using a random-effects model. Results . The literature search produced 123 unique citations. One hundred sixteen records were excluded. The meta-analysis included seven studies (321 patients) on EEG-Biofeedback and EMG-Biofeedback. In comparison to control groups, biofeedback (BFB) significantly reduced pain intensity with a large effect size (; 95% CI: 0.22–1.36). Subgroup analyses revealed that only EMG-BFB and not EEG-BFB significantly reduced pain intensity in comparison to control groups (; 95% CI: 0.11–1.62). BFB did not reduce sleep problems, depression, fatigue, or health-related quality of life in comparison to a control group. Discussion . The interpretation of the results is limited because of a lack of studies on the long-term effects of EMG-BFB in FMS. Further research should focus on the long-term efficacy of BFB in fibromyalgia and on the identification of predictors of treatment response.

Objective: Fibromyalgia syndrome (FMS) is a chronic rheumatological condition which could be characterized by generalized pain and fatigue. Cognitive and behavioral therapy has been found to be a suitable technique in the management of FMS. This study intends to evaluate the efficacy of electromyography (EMG) biofeedback to reduce pain in patients with FMS. Materials and Methods: A randomized controlled trial involving two groups of FMS patients, one receiving EMG biofeedback and the other a sham biofeedback, was carried out. The assessment tools included in the study were fibromyalgia impact questionnaire (FIQ), visual analogue scale (VAS), six-minute walk test (SMWT) and number of tender points; and tenderness of each tender point was done for both the groups. Statistics: A Student's 't' test was used to study the test for significance. Results: After using biofeedback, the mean VAS scores and the mean number of tender points were found to be 3 out of 10 and 6 out of 18 respectively. Subjective analysis from both groups showed improvement in physical and psychological realms. Statistical significance (P < 0.001) was observed for decrease in pain and number of tender points. ANOVA analysis revealed a significant decrease in VAS, FIQ and tender points within the groups. Conclusion: Biofeedback as a treatment modality reduces pain in patients with FMS, along with improvements in FIQ, SMWT and the number of tender points.

EEG Biofeedback (Neurofeedback-NFB) is a learning strategy that enables people to alter their brainwaves. In the present case study, we applied a NFB protocol on three patients with Fibromyalgia Syndrome (FMS). The existing symptoms and clinical conditions of the patients attributed to FMS, Visual Analog Scale for pain and fatigue, Hamilton Depression and Anxiety Inventory Scales, Beck Depression and Anxiety Inventory Scales, and SF-36 were recorded before and after NFB training. Most of the symptoms were decreased after ten sessions. There was also improvement in all of the scales after the treatment. The results of the present study may suggest NFB training as a novel treatment method in FMS.
Treatment of Fibromyalgia Syndrome Using Low-Intensity Neurofeedback with the Flexyx Neurotherapy System: A Randomized Controlled Clinical Trial
Background. Treatment of fibromyalgia syndrome (FMS) remains a clinical challenge. Pain, somatic and cognitive symptoms may be due to neurosensitization involving CNS-activated autonomic and musculoskeletal reactions, associated with EEG abnormalities that may respond to brainwave-based stimulation biofeedback. This study's objective was to examine the efficacy and safety of a novel EEG neurobiofeedback treatment, the Flexyx Neurotherapy System® (FNS), and electrophysiological responses in persons with fibromyalgia. Methods. Arandomized, double-blind, placebo-controlled clinical trial was conducted in two private practices: a free-standing neurobiofeedback center and a rheumatologist's office at an academic medical center. Sixty-four participants with FMS (American College of Rheumatology criteria; Wolfe et al., 1990) for at least three years and symptoms for at least 48 months with no recent remission were randomized to treatment. A total of 22 treatment sessions were administered over at least 11 weeks of active (n = 33) or sham (n = 31) FNS therapy. Primary efficacy measures were the Clinical Global Impressions improvement scores, Clinician (CGI-I) and Participant (PGI-I) versions. Secondary outcomes included dolorimetry and tender point count, questionnaires (fibromyalgia symptom scales, CNS Dysfunction Questionnaire, Fibromyalgia Impact Questionnaire, Symptom Checklist-90-R), and EEG activity (delta, alpha, total amplitude). Results. More participants treated with active FNS than with sham improved partially or fully on the CGI-I at session 22 (p = .01) and follow-up (p = .04). The active FNS group had a higher CGI-I full response rate at session 22 (p < .05) but not at one-week post-treatment (p = .07). Significant active versus sham PGI-I responses were not detected (p>.10). There was no significant treatment effect on any secondary outcome measure and no specific symptom improved preferentially with active compared with sham FNS. The most commonly reported side effect was fatigue/tiredness. Pre-treatment delta/alpha EEG amplitude ratio > 1 was associated with PGI-I (but not CGI-I) response independent of treatment group assignment. Conclusion. FNS monotherapy is insufficient for treating chronic, nonremitting FMS.

Thirty patients from a private clinical practice who met the 1990 American College of Rheumatology criteria for fibromyalgia syndrome (FS) were followed prospectively through a brainwave-based intervention known as electroencephalograph (EEG)-driven stimulation or EDS. Patients were initially treated with EDS until they reported noticeable improvements in mental clarity, mood, and sleep. Self-reported pain, then, having changed from vaguely diffuse to more specifically localized, was treated with very modest amounts of physically oriented therapies. Pre- to posttreatment and extended follow-up comparisons of psychological and physical functioning indices, specific FS symptom ratings, and EEG activity revealed statistically significant improvements. EDS appeared to be the prime initiator of therapeutic efficacy. Future research is justified for controlled clinical trials and to better understand disease mechanisms. © 2001 John Wiley & Sons, Inc.
