          Abstract

          RESUMO Objetivo Investigar os ensaios clínicos randomizados sobre a ação da acupuntura auricular para a dor crônica nas costas em adultos, identificar os desfechos mais utilizados para avaliar essa condição, o protocolo utilizado para aplicar a intervenção e identificar nos estudos qual o efeito da terapia sobre a intensidade da dor. Método Revisão sistemática e metanálise, conduzidas entre junho de 2017 e maio de 2018, nas bases de dados PubMed, CINAHL, PEDro, Embase, Scopus e na Biblioteca Virtual em Saúde. Listas de referências de revisões sistemáticas também foram exploradas. Resultados Foram localizados 427 estudos, 15 incluídos na análise qualitativa, e sete na análise quantitativa. A acupuntura auricular obteve resultados positivos em 80% dos estudos. Os desfechos mais utilizados foram a intensidade e a qualidade da dor, consumo de medicação, incapacidade física e qualidade de vida. Não há padronização no protocolo de acupuntura auricular para dor crônica nas costas. Os resultados da metanálise apontaram que a acupuntura auricular foi eficaz em reduzir os escores de intensidade da dor (p=0,038). Conclusão A acupuntura auricular é uma prática promissora para o tratamento da dor crônica nas costas em adultos.

          ABSTRACT Objective To investigate randomized clinical trials on the action of auricular acupuncture for chronic back pain in adults, and to identify the most commonly used outcomes for assessing this condition, the protocol used for applying the intervention, and the efficacy of the therapy on pain intensity. Method A systematic review and a metanalysis were carried out between June 2017 and May 2018, based on the PubMed, CINAHL, PEDro, Embase, Scopus, and the Virtual Health Library databases. Reference lists of systematic reviews were also explored. Results 427 studies were located, 15 included in the qualitative analysis, and seven in the quantitative analysis. Auricular acupuncture led to positive results in 80% of the studies. The most commonly used outcomes were pain intensity and quality, medication consumption, physical disability, and quality of life. There is a lack of protocol standardization for auricular acupuncture for chronic back pain. The metanalysis results showed that auricular acupuncture was effective in reducing pain intensity scores (p=0.038). Conclusion Auricular acupuncture is a promising practice for the treatment of chronic back pain in adults.

          Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013.

            Minimal changes in health status questionnaires: distinction between minimally detectable change and minimally important change

            Changes in scores on health status questionnaires are difficult to interpret. Several methods to determine minimally important changes (MICs) have been proposed which can broadly be divided in distribution-based and anchor-based methods. Comparisons of these methods have led to insight into essential differences between these approaches. Some authors have tried to come to a uniform measure for the MIC, such as 0.5 standard deviation and the value of one standard error of measurement (SEM). Others have emphasized the diversity of MIC values, depending on the type of anchor, the definition of minimal importance on the anchor, and characteristics of the disease under study. A closer look makes clear that some distribution-based methods have been merely focused on minimally detectable changes. For assessing minimally important changes, anchor-based methods are preferred, as they include a definition of what is minimally important. Acknowledging the distinction between minimally detectable and minimally important changes is useful, not only to avoid confusion among MIC methods, but also to gain information on two important benchmarks on the scale of a health status measurement instrument. Appreciating the distinction, it becomes possible to judge whether the minimally detectable change of a measurement instrument is sufficiently small to detect minimally important changes.

              Sham acupuncture may be as efficacious as true acupuncture: a systematic review of clinical trials.

              This study sought to determine whether sham acupuncture is as efficacious as true acupuncture, as defined by traditional acupuncture theories. A systematic review was conducted of clinical trials that used sham acupuncture controls with needle insertion at wrong points (points not indicated for the condition) or non-points (locations that are not known acupuncture points). This study used a convenience sample of 229 articles resulting from a PubMed search using the keyword "acupuncture" and limited to "clinical trials" published in English in 2005 or 2006. Studies were categorized by use of wrong points versus non-points and the use of normal insertion and stimulation versus superficial insertion or minimal stimulation. Thirty-eight acupuncture trials were identified. Most studies (22/38 = 58%) found no statistically significant difference in outcomes, and most of these (13/22 = 59%) found that sham acupuncture may be as efficacious as true acupuncture, especially when superficial needling was applied to non-points. The findings cast doubt on the validity of traditional acupuncture theories about point locations and indications. Scientific rationales for acupuncture trials are needed to define valid controls, and the theoretical basis for traditional acupuncture practice needs to be re-evaluated.
