Review Meta Analysis Comparative Study
Systematic review of randomized controlled trials of nonpharmacological interventions for fibromyalgia.
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. ⋯ 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.

Meta Analysis
Efficacy of spinal cord stimulation: 10 years of experience in a pain centre in Belgium.
Spinal cord stimulation is a minimally invasive mode of treatment in the management of certain forms of chronic pain that do not respond to conventional pain therapy. Several authors have reported encouraging findings with this technique. Over a 10-year period in a single centre, 254 patients were subjected to a trial period of spinal cord stimulation with an externalized pulse generator. ⋯ The aim of this study was to evaluate the efficacy of an implanted spinal cord stimulation system in terms of pain relief and quality of life and to assess the accuracy of the patient selection criteria. The results of this study demonstrate a high success rate as evaluated by the patients' own assessments--68% of the patients rated the result of the treatment as excellent to good after an average follow-up of almost 4 years. The resumption of work by 31% of patients who had been working before the onset of pain supports these positive findings.

Pain is the major complaint of the estimated one million U. S. consumers who use acupuncture each year. Although acupuncture is widely available in chronic pain clinics, the effectiveness of acupuncture for chronic pain remains in question. ⋯ Six or more acupuncture treatments were significantly associated with positive outcomes (P=0.03) even after adjusting for study quality. We conclude there is limited evidence that acupuncture is more effective than no treatment for chronic pain; and inconclusive evidence that acupuncture is more effective than placebo, sham acupuncture or standard care. However, we have found an important relationship between the methodology of the studies and their results that should guide future research.

A computer and a hand search of the literature recovered 33 papers from which 25 trials suitable for meta-analysis were identified. We compared the effectiveness of cognitive-behavioural treatments with the waiting list control and alternative treatment control conditions. There was a great diversity of measurements which we grouped into domains representing major facets of pain. ⋯ Differences on the following domains were not significant; mood/affect (depression and other, non-depression, measures), cognitive coping and appraisal (negative, e.g. catastrophization), and social role functioning. We conclude that active psychological treatments based on the principle of cognitive behavioural therapy are effective. We discuss the results with reference to the complexity and quality of the trials.

Meta AnalysisConservative management of mechanical neck disorders. A systematic overview and meta-analysis.
This overview reports the efficacy of conservative treatments (drug therapy, manual therapy, patient education, physical medicine modalities) in reducing pain in adults with mechanical neck disorders. ⋯ Within the limits of methodologic quality, the best available evidence supports the use of manual therapies in combination with other treatments for short-term relief of neck pain. There is some support for the use of electromagnetic therapy and against the use of laser therapy. In general, other interventions have not been studied in enough detail adequately to assess efficacy or effectiveness. This overview provides the foundation for an evidence-based approach to practice. More robust design and methodology should be used in future research, in particular, the use of valid and reliable outcomes measures.
