[Complementary and alternative therapies for fibromyalgia syndrome. Systematic review, meta-analysis and guideline]

BACKGROUND

The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011.

MATERIALS AND METHODS

The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The recommendations were based on level of evidence, efficacy (meta-analysis of the outcomes pain, sleep, fatigue and health-related quality of life), acceptability (total dropout rate), risks (adverse events) and applicability of treatment modalities in the German health care system. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies.

RESULTS AND CONCLUSION

Meditative movement therapies (qi gong, tai chi, yoga) are strongly recommended. Acupuncture can be considered. Mindfulness-based stress reduction as monotherapy and dance therapy as monotherapy are not recommended. Homeopathy is not recommended. In a minority vote, homeopathy was rated as "can be considered". Nutritional supplements and reiki are not recommended. The English full-text version of this article is available at SpringerLink (under "Supplemental").

Role of diet in rheumatic disease

Millions of people suffer from rheumatic diseases such as gout, fibromyalgia, osteoarthritis, and rheumatoid arthritis. These can be incapacitating and detrimental to quality of life. Diet, nutrition, and weight loss have shown promise in alleviating some of this disease burden. These lifestyle changes may give patients a feeling of control and ownership over their disease as well as a nonpharmacologic means of treatment. This article reviews the available research on the effects of diet and nutrition on rheumatoid disease.

[Alternative and complementary therapies in fibromyalgia syndrome]

INTRODUCTION

Interdisciplinary S3 level guidelines were devised in cooperation with 8 medical, 2 psychological and 2 patient support groups. Results were elaborated in a multilevel group process.

METHODS

On the bases of the "Cochrane Library" (1993-2006), "Medline" (1980-2006), "PsychInfo" (2006) and "Scopus" (2006) controlled studies and meta-analyses of controlled studies were analyzed.

RESULTS

Only few controlled studies were found supporting in part the effectiveness of CAM therapies in the treatment of fibromyalgia syndrome. Due to the lack of information on long term efficacy and cost-effectiveness, only limited recommendations for CAM therapies can be given.

CONCLUSION

Within a multicomponent therapy setting, selective CAM therapies (acupuncture, vegetarian diet, homeopathy, Tai Chi, Qi Gong, music-oriented and body-oriented therapies) can be recommended for a limited period of time.

Long-term follow up of a physical therapy programme for patients with fibromyalgia syndrome

The purpose of this study was to evaluate, in a long-term perspective, the impact of a physical therapy-based educational programme on patients with fibromyalgia syndrome (FMS). The programme includes information about the syndrome, information about pain and muscle physiology, training in warm water, stretching, body awareness therapy and relaxation in groups of 15 patients twice weekly, 2 hours during 10 weeks. A total of 240 patients with FMS participated in the study before and immediately after the programme and at a follow up with a mean of 35 months after the programme. Health status as measured with the Fibromyalgia Impact Questionnaire was answered by the patients at all three measurement points. Questionnaires concerning self-care, self-motivation and sense of coherence (SOC) were distributed at the follow up. The results showed a significant improvement on several symptoms when comparing before and after the programme, and at the time of follow up the patients' rated well-being was still improved. The results also showed that the patients' pretreatment perception of symptoms, well-being and SOC are predictors to the perception of general health at the follow up of a physical therapy programme. The conclusion is that a physical therapy programme for patients with FMS may have a positive impact on patients' general well-being but not on other symptoms.

Systematic review of randomized controlled trials of nonpharmacological interventions for fibromyalgia

OBJECTIVE

Little is known of the effectiveness of nonpharmacological interventions for fibromyalgia syndrome (FMS). The authors therefore carried out a systematic review from 1980 to May 2000 of randomized controlled trials (RCTs) of nonpharmacological interventions for FMS.

METHOD

A search of computerized databases was supplemented by hand searching of bibliographies of key publications. The methodological quality of studies included in the review was evaluated independently by two researchers according to a set of formal criteria. Discrepancies in scoring were resolved through discussion.

RESULTS

The review yielded 25 RCTs, and the main categories of interventions tested in the studies were exercise therapy, educational intervention, relaxation therapy, cognitive-behavioral therapy, acupuncture, and forms of hydrotherapy. Methodological quality of studies was fairly low (mean score = 49.5/100). Most studies had small samples (median for individual treatment groups after randomization = 20), and the mean power of the studies to detect a medium effect ( > or = 0.5) was 0.36. Sixteen studies had blinded outcome assessment, but patients were blinded in only 6 studies. The median longest follow-up was 16 weeks. Statistically significant between-group differences on at least one outcome variable were reported in 17 of the 24 studies.

CONCLUSIONS

The varying combinations of interventions studied in the RCTs and the wide range of outcome measures used make it hard to form conclusions across studies. Strong evidence did not emerge in respect to any single intervention, though preliminary support of moderate strength existed for aerobic exercise. There is a need for larger, more methodologically rigorous RCTs in this area.

Physical and other non-pharmacological interventions for fibromyalgia

There is little empirical evidence for the effectiveness of physical and other non-pharmacological approaches to the management of fibromyalgia. Although a number of studies have been conducted into such approaches, many of these are uncontrolled, and relatively few randomized controlled trials of appropriate size and methodological rigour have been carried out. This chapter provides an overview of the evidence available under the following headings: exercise, EMG biofeedback training, electrotherapy and acupuncture, patient education and self-management programmes, multimodal treatment approaches, and other interventions. It is hard to reach firm conclusions from the literature, owing to the variety of interventions that have been evaluated and the varying methodological quality of the studies concerned. Nonetheless, in terms of specific interventions, exercise therapy has received a moderate degree of support from the literature, and has been subjected to more randomized studies than any other intervention. In contrast, there is little or no evidence available for most types of electrotherapy. In terms of overall management strategies, a multimodal programme of management, including physical, psychological and educational components and delivered in a multidisciplinary setting, has gained some support from descriptive and experimental studies, and accords with current understanding of the aetiology and clinical features of fibromyalgia. There is a clear need for further systematic evaluation of the effectiveness of non-pharmacological treatment approaches in fibromyalgia.
