Results of a pilot study of a cooling mattress pad to reduce vasomotor symptoms and improve sleep.

OBJECTIVE: This single-arm pilot study was designed to generate pilot data on the use of a cooling mattress pad system on vasomotor symptoms (VMS; hot flashes and/or night sweats), self-assessed sleep, and daily hot flash interference among perimenopausal and postmenopausal women. METHODS: A total of 15 perimenopausal and postmenopausal women aged 45 to 59 years experiencing four or more VMS per day were recruited from the community. After completion of baseline questionnaires and a 2-week daily diary to confirm VMS eligibility, all women received a cooling mattress pad system to use at night for 8 weeks, during which time they continued to complete their daily diaries to record VMS frequency and severity. The primary study outcome was change from baseline in VMS frequency. Secondary outcomes were sleep quality, measured by the Pittsburgh Sleep Quality Index, and hot flash interference with daily life, assessed by the Hot Flash Related Daily Interference Scale, where higher sores indicate worse sleep quality and higher interference, respectively. We used repeated-measures methods (analysis of covariance, paired t tests, and McNemar test) to evaluate outcomes. RESULTS: VMS frequency significantly declined by 52% at 8 weeks ( P < 0.0001). Mean total Pittsburgh Sleep Quality Index score significantly declined 3.27 points from 11.14 at baseline to 7.87 at follow-up ( P = 0.011). The total Hot Flash Related Daily Interference Scale score significantly declined from 4.16 at baseline to 1.92 at follow-up ( P = 0.011). CONCLUSIONS: Women who used a cooling mattress pad system experienced significant and clinically meaningful reductions in VMS frequency, sleep disturbance, and hot flash interference with daily activities over an 8-week period. These results provide preliminary evidence suggesting that a cooling mattress pad used while sleeping can provide a nonpharmacological option to reduce VMS and sleep disturbance for women experiencing menopausal hot flashes.

Incorporating Acupuncture Into American Healthcare: Initiating a Discussion on Implementation Science, the Status of the Field, and Stakeholder Considerations.

INTRODUCTION: The field of implementation science is the study of methods that promote the uptake of evidence-based interventions into healthcare policy and practice. While acupuncture has gained significant traction in the American healthcare landscape, its journey has been somewhat haphazard and non-linear. METHODS: In June 2019, a group of thirty diverse stakeholders was convened by the Society for Acupuncture Research with the support of a Patient Centered Outcomes Research Institute, Eugene Washington Engagement Award. This group of stakeholders represented a diverse mix of patients, providers, academicians, researchers, funders, allied health professionals, insurers, association leaders, certification experts, and military program developers. The collective engaged in discussion that explored acupuncture's status in healthcare, including reflections on its safety, effectiveness, best practices, and the actual implementation of acupuncture as seen from diverse stakeholder viewpoints. OBJECTIVES: A primary goal was to consider how to utilize knowledge from the field of implementation science more systematically and intentionally to disseminate information about acupuncture and its research base, through application of methods known to implementation science. The group also considered novel challenges that acupuncture may present to known implementation processes. FINDINGS: This article summarizes the initial findings of this in-person meeting of stakeholders and the ongoing discussion among the subject matter experts who authored this report. The goal of this report is to catalyze greater conversation about how the field of implementation science might intersect with practice, access, research, and policymaking pertaining to acupuncture. Core concepts of implementation science and its relationship to acupuncture are introduced, and the case for acupuncture as an Evidence Based Practice (EBP) is established. The status of the field and current environment of acupuncture is examined, and the perspectives of four stakeholder groups--patients, two types of professional practitioners, and researchers--are explored in more detail.

Use of Ayurveda in the Treatment of Type 2 Diabetes Mellitus.

BACKGROUND: Ayurveda is an ancient medicine practice that is emerging in the United States as a complementary and alternative treatment for chronic illness. Type 2 diabetes is a chronic illness that has major long-term implications for individuals suffering from the disease as well as the health-care system as a whole. Modifications in diet, exercise, and lifestyle are all important factors in successful treatment of type 2 diabetes and are incorporated into the ancient Indian medicinal practice of Ayurveda.Review Summary: This review summarizes the available evidence for the use of Ayurvedic therapies in the treatment of type 2 diabetes. For the treatment of type 2 diabetes, Ayurvedic practices primarily emphasizes the use of herbal supplements; however, exercise, weight management, and various supplemental procedures are included in Ayurvedic practices. The goal of Ayurvedic practices on the treatment of type 2 diabetes like in Western medicine focuses on bringing the hemoglobin A1c (HbA1c) value into a therapeutic range. Where Ayurveda differs is that it looks at the functionality of a person in the context of striking a balance between the life forces or doshas that each individual possesses. Finally, this article includes a case study received from AyurVAID clinic in Bangalore, India that details the specific Ayurvedic intervention used in a patient, bringing his HbA1c from a level of 11.2 to 5.7 over the course of 9 months. CONCLUSION: Patients with type 2 diabetes may inquire about current complementary and alternative therapies available for the treatment of their disease. Awareness of such modalities is necessary for effective patient counseling and care. The benefits of offering a wide array of treatment options include possible reduction of HbA1c and of comorbidities with adjunct use of supplements and mind-body practices.

Assessing heterogeneity of treatment effect analyses in health-related cluster randomized trials: A systematic review.

BACKGROUND: Cluster-randomized trials (CRTs) are being increasingly used to test a range of interventions, including medical interventions commonly used in clinical practice. Policies created by the NIH and the Food and Drug Administration (FDA) require the reporting of demographics and the examination of demographic heterogeneity of treatment effect (HTE) for individually randomized trials. Little is known about how frequent demographics are reported and HTE analyses are conducted in CRTs. OBJECTIVES: We sought to understand the prevalence of HTE analyses and the statistical methods used to conduct them in CRTs focused on treating cardiovascular disease, cancer, and chronic lower respiratory diseases. Additionally, we also report on the proportion of CRTs that reported on baseline demographics of its populations and conducted demographic HTE analyses. DATA SOURCES: We searched PubMed and Embase for CRTs published between 1/1/2010 and 3/29/2016 that focused on treating the top 3 Center for Disease Control causes of death (cardiovascular disease, chronic lower respiratory disease, and cancer). Evidence Screening And Review: Of 1,682 unique titles, 117 abstracts were screened. After excluding 53 articles, we included 64 CRT publications and abstracted information on study characteristics and demographic information, statistical analysis, HTE analysis, and study quality. RESULTS: Age and sex were reported in greater than 95.3% of CRTs, while race and ethnicity were reported in only 20.3% of CRTs. HTE analyses were conducted in 28.1% (n = 18) of included CRTs and 77.8% (n = 12) were prespecified analyses. Four CRTs conducted a demographic subgroup analysis. Only 6/18 CRTs used interaction testing to determine whether HTE existed. CONCLUSIONS: Baseline demographic reporting was high for age and sex in CRTs, but was uncommon for race and ethnicity. HTE analyses were uncommon and was rare for demographic subgroups, which limits the ability to examine the extent of benefits or risks for treatments tested with CRT designs.

Nonpharmacological Self-Management of Migraine Across Social Locations: An Equity-Oriented, Qualitative Analysis.

BACKGROUND: Migraine is a disabling neurological disorder and the sixth biggest cause of disability worldwide. The World Health Organization has declared migraine a major public health problem due to a paucity of knowledge about cause and effective treatment options. Both in incidence and severity, migraine disproportionately affects people occupying marginalized social locations (SL). Managed pharmacologically, migraine is treated with daily preventive and as-needed abortive medications. Both come with high literal and figurative costs: intolerable side effects, medication interactions, and prohibitive prices. Cost prohibitive, ineffective, and unsustainable pharmacological treatment options have contributed to high levels of interest in complementary approaches by people with migraine, but little is known about their motivations, patterns of use or access, or how these may vary by SL. METHOD: We conducted focus groups with 30 people with migraine to explore their desires and recommendations for migraine clinicians and researchers. We used qualitative content analysis to identify themes.Outcomes: We identified 4 themes: a more holistic, collaborative, long-term treatment approach; medication as a short-term solution; high personal and economic costs of medication; and desire for more information and access to natural approaches. Across SL, participants expressed keen interest in integrative approaches and wanted better access to complementary modalities. Participants in marginalized SL described reliance on traditional/folk remedies, including engagement with family and community healers, who they described as more affordable and culturally accessible. CONCLUSIONS: Holistic and integrative approaches were preferred over medication as long-term migraine management strategies. However, people in marginalized SL, while disproportionately disabled by migraine, did not feel as comfortable accessing integrative approaches through currently available channels. Engaging with these communities and using a critical lens to explore barriers to access can develop options to make complementary modalities more approachable, while also attending to systemic blind spots that may unintentionally alienate socially marginalized groups.

A pooled analysis of three studies of nonpharmacological interventions for menopausal hot flashes.

OBJECTIVE: The aim of the study was to conduct a pooled analysis of three published trials of nonpharmacological interventions for menopausal hot flashes to compare the effectiveness of interventions. METHODS: Data from three randomized controlled trials of interventions for hot flashes (two acupuncture trials, one yoga trial) were pooled. All three studies recruited perimenopausal or postmenopausal women experiencing ≥4 hot flashes/d on average. The primary outcome for all three studies was frequency of hot flashes as measured by the Daily Diary of Hot Flashes. Study 1 participants were randomly assigned to 8 weeks of acupuncture treatments (active intervention), sham acupuncture (attention control), or usual care. Study 2 participants were randomly assigned to 10 weeks of yoga classes, health and wellness education classes (attention control), or waitlist control. Study 3 randomly assigned participants to 6 months of acupuncture or waitlist control. To standardize the time frame for these analyses, only the first 8 weeks of intervention from all three studies were used. RESULTS: The three active interventions and the two attention control groups had statistically similar trends in the percentage reduction of hot flashes over 8 weeks, ranging from 35% to 40%. These five groups did not differ significantly from each other, but all showed significantly greater reduction in hot flash frequency compared with the three usual care/waitlist groups. CONCLUSION: Acupuncture, yoga, and health and wellness education classes all demonstrated statistically similar effectiveness in reduction of hot flash frequency compared with controls.

A Critical Exploration of Migraine as a Health Disparity: the Imperative of an Equity-Oriented, Intersectional Approach.

PURPOSE OF REVIEW: Despite recognition of rising prevalence and significant burden, migraine remains underestimated, underdiagnosed, and undertreated. This is especially true among groups who have been historically, socially, and economically marginalized such as communities of color, women, people experiencing poverty, people with lower levels of education, and people who hold more than one of these marginalized identities. While there is growing public and professional interest in disparities in migraine prevalence, there is a paucity of research focusing on racial/ethnic and socioeconomic disparities, and the social and structural determinants of health and equity that perpetuate these disparities. From a health equity perspective, migraine research and treatment require an examination not only of biological and behavioral factors, but of these identities and underlying, intersecting social and structural determinants of health. RECENT FINDINGS: Significant disparities in migraine incidence, prevalence, migraine-related pain and disability, access to care, and quality of care persist among marginalized and underserved groups: African Americans, Hispanics, people experiencing poverty, un- or under-employment, the un- and under-insured, people who have been exposed to stressful and traumatic events across the lifespan, and people experiencing multiple, overlapping marginalized identities. These same groups are largely underrepresented in migraine research, despite bearing disproportionate burden. Current approaches to understanding health disparities in migraine largely assume an essentializing approach, i.e., documenting differences between single identity groups-e.g., race or income or education level-rather than considering the mechanisms of disparities: the social and structural determinants of health. While disparities in migraine are becoming more widely acknowledged, we assert that migraine is more aptly understood as a health equity issue, that is, a condition in which many of the health disparities are avoidable. It is important in research and clinical practice to consider perspectives that incorporate a cultural understanding of racial, ethnic, and socioeconomic identity within and across all levels of society. Incorporating perspectives of intersectionality provides a strong foundation for understanding the role of these complex combination of factors on migraine pain and treatment. We urge the adoption of intersectional and systems perspectives in research, clinical practice, and policy to examine (1) interplay of race, gender, and social location as key factors in understanding, diagnosing, and treating migraine, and (2) the complex configurations of social and structural determinants of health that interact to produce health inequities in migraine care. An intentional research and clinical focus on these factors stands to improve how migraine is identified, documented, and treated among marginalized populations.

A Qualitative, Systems Thinking Approach to Study Self-Management in Women With Migraine.

BACKGROUND: A dearth of effective and affordable treatment options has rendered nonpharmacological self-management a crucial part of living with migraine-a debilitating neurobiological condition without cure that disproportionately disables vulnerable women. OBJECTIVE: The aim of the study was to describe the development and use of a systems thinking, problem-structuring data collection approach that was applied to the study of migraine self-management with women in diverse social locations. METHODS: Two systems mapping activities were developed for use in focus groups: one to unpack a migraine episode (system support map) and the other (connection circle [CC]) to construct a mental model of self-management. Later in the process, a strengths-based problem-solving tool was developed to replace the CC. RESULTS: The CCs-often enlightening for affluent participants-left marginalized women feeling overwhelmed and defeated, as a solution to one challenge became the cause of another. Through constant comparison analysis, we recalibrated the approach using a theory, clinical experience, and participant feedback and replaced the CC with a strengths-based problem-solving activity highlighting relationships and trade-offs in a more agential, actionable way. DISCUSSION: Bringing a critical lens and strengths-based approaches to work with vulnerable populations can replace traditional deficit thinking in healthcare, developing options for leveraging resources and understanding complex health behaviors without losing sight of systemic, distributional justice issues. These systems thinking tools can provide a way to extrapolate the complexities of actual self-management behaviors and challenges faced by vulnerable women with migraine versus what they may be instructed to do by a medical model that does not always account for the social and structural determinants of equity and health.

Nonpharmacologic Treatments for Attention-Deficit/Hyperactivity Disorder: A Systematic Review.

CONTEXT: Nonpharmacologic treatments for attention-deficit/hyperactivity disorder (ADHD) encompass a range of care approaches from structured behavioral interventions to complementary medicines. OBJECTIVES: To assess the comparative effectiveness of nonpharmacologic treatments for ADHD among individuals 17 years of age and younger. DATA SOURCES: PubMed, Embase, PsycINFO, and Cochrane Database of Systematic Reviews for relevant English-language studies published from January 1, 2009 through November 7, 2016. STUDY SELECTION: We included studies that compared any ADHD nonpharmacologic treatment strategy with placebo, pharmacologic, or another nonpharmacologic treatment. DATA EXTRACTION: Study design, patient characteristics, intervention approaches, follow-up times, and outcomes were abstracted. For comparisons with at least 3 similar studies, random-effects meta-analysis was used to generate pooled estimates. RESULTS: We identified 54 studies of nonpharmacologic treatments, including neurofeedback, cognitive training, cognitive behavioral therapy, child or parent training, dietary omega fatty acid supplementation, and herbal and/or dietary approaches. No new guidance was identified regarding the comparative effectiveness of nonpharmacologic treatments. Pooled results for omega fatty acids found no significant effects for parent rating of ADHD total symptoms (n = 411; standardized mean difference -0.32; 95% confidence interval -0.80 to 0.15; I2 = 52.4%; P = .10) or teacher-rated total ADHD symptoms (n = 287; standardized mean difference -0.08; 95% confidence interval -0.47 to 0.32; I2 = 0.0%; P = .56). LIMITATIONS: Studies often did not reflect the primary care setting and had short follow-up periods, small sample sizes, variations in outcomes, and inconsistent reporting of comparative statistical analyses. CONCLUSIONS: Despite wide use, there are significant gaps in knowledge regarding the effectiveness of ADHD nonpharmacologic treatments.

Acupuncture for Chronic Pain in the Vermont Medicaid Population: A Prospective, Pragmatic Intervention Trial.

INTRODUCTION: In response to the opioid crisis, the 2016 Vermont legislature commissioned a study to assess acupuncture for patients with chronic pain in the Vermont Medicaid population. OBJECTIVE: To assess the feasibility, acceptability, and effectiveness of acupuncture provided by licensed acupuncturists for Vermont Medicaid patients with chronic pain. METHODS: A total of 156 Medicaid patients with chronic pain were offered up to 12 acupuncture treatments within a 60-day period at the offices of 28 Vermont licensed acupuncturists. PROMIS® questionnaires were administered prior to and at the end of the treatment period to assess changes in pain intensity, pain interference, physical function, fatigue, anxiety, depression, sleep disturbance, and social isolation. Questionnaires also captured patients' overall impressions of treatments as well as self-reported changes in medication use and work function. RESULTS: One hundred eleven women (71%) and 45 men (29%) with a wide range of pain complaints received a mean of 8.2 treatments during the intervention period. Measurements captured prior to and at the end of the treatment period showed significant improvements in group mean pain intensity, pain interference, physical function, fatigue, anxiety, depression, sleep disturbance, and social isolation as assessed by Patient-Reported Outcomes Measurement Information System (PROMIS) measures (paired t tests, P < .01). Fifty-seven percent of patients using analgesic (nonopioid) medication reported reductions in use. Thirty-two percent of patients using opioid medication reported reductions in use of opioid medication following the intervention. Seventy-four percent of employed patients reported improved capacity to work. Ninety-six percent of patients said that they would recommend acupuncture to others with chronic pain, and 91% reported qualitative improvements, including physical (31%), functional/behavioral (29%), and psycho-emotional (24%) improvements. CONCLUSIONS: Our findings demonstrate that acupuncture treatment for chronic pain is feasible and well received by patients in the Vermont Medicaid population. Receiving care from Licensed Acupuncturists was associated with significant improvements in physical, functional, psycho-emotional, and occupational outcomes compared with before receiving acupuncture treatments.

Systematic review and meta-analysis of endovascular and surgical revascularization for patients with chronic lower extremity venous insufficiency and varicose veins.

BACKGROUND: Chronic lower extremity venous disease (LECVD) is twice as prevalent as coronary heart disease, and invasive therapies to treat LECVD accounted for an estimated $290 million in Medicare expenditures in 2015. Despite increasing use of these invasive therapies, their comparative effectiveness is unknown. METHODS: We conducted a systematic review and meta-analysis of treatments for patients (symptomatic and asymptomatic) with lower extremity varicosities and/or lower extremity chronic venous insufficiency/incompetence/reflux. We searched PubMed, Embase, and the Cochrane Database of Systematic Reviews for relevant English-language studies published from January 2000 to July 2016. We included comparative randomized controlled trials (RCTs) with >20 patients and observational studies with >500 patients. Short-, intermediate-, and long-term outcomes of placebo, mechanical compression therapy, and invasive therapies (surgical and endovascular) were included. Quality ratings and evidence grading was performed. Random-effects models were used to compute summary estimates of effects. RESULTS: We identified a total of 57 studies representing 105,878 enrolled patients, including 53 RCTs comprised of 10,034 patients. Among the RCTs, 16 were good quality, 28 were fair quality, and 9 were poor quality. Allocation concealment, double blinding, and reporting bias were inadequately addressed in 25 of 53 (47%), 46 of 53 (87%), and 15 of 53 (28.3%), respectively. Heterogeneity in therapies, populations, and/or outcomes prohibited meta-analysis of comparisons between different endovascular therapies and between endovascular intervention and placebo/compression. Meta-analysis evaluating venous stripping plus ligation (high ligation/stripping) compared with radiofrequency ablation revealed no difference in short-term bleeding (odds ratio [OR]=0.30, 95% CI -0.16 to 5.38, P=.43) or reflux recurrence at 1-2 years (OR=0.76, 95% CI 0.37-1.55, P=.44). Meta-analysis evaluating high ligation/stripping versus endovascular laser ablation revealed no difference in long-term symptom score (OR 0.02, 95% CI -0.19 to 0.23, P=.84) or quality of life at 2 years (OR 0.06, 95% CI -0.12 to 0.25, P=.50). CONCLUSIONS: The paucity of high-quality comparative effectiveness and safety data in LECVD is concerning given the overall rise in endovascular procedures. More high-quality studies are needed to determine comparative effectiveness and guide policy and practice.

Management of Menopause Symptoms with Acupuncture: An Umbrella Systematic Review and Meta-Analysis.

OBJECTIVES: Vasomotor symptoms (VMSs) are the most common symptoms reported during menopause. Although hormone therapy is effective for reducing VMSs, its use is restricted in some women. Many women with VMSs thus seek nonhormonal, nonpharmacologic treatment options such as acupuncture. DESIGN: An umbrella systematic review (SR) was conducted, supplemented by a search of published randomized controlled trials (RCTs), that assessed the effectiveness of acupuncture for VMSs, health-related quality of life (HRQOL), and adverse effects of treatment in perimenopausal or postmenopausal women. Meta-analyses were conducted using a random-effects model when data were sufficient. RESULTS: Three SRs and four new RCTs were identified that met eligibility criteria. Meta-analyses of this study revealed statistically significant standardized mean differences (SMDs) associated with acupuncture compared with no acupuncture at reducing VMS frequency (SMD -0.66, 95% confidence interval [CI] -1.06 to -0.26, I2 = 61.7%, 5 trials) and VMS severity (SMD -0.49, 95% CI -0.85 to -0.13, I2 = 18.1%, 4 trials) and improving HRQOL outcomes (SMD -0.93, 95% CI -1.20 to -0.67, I2 = 0.0%, 3 trials). SMDs were smaller or not statistically significant when acupuncture was compared with sham acupuncture. CONCLUSIONS: Evidence from RCTs supports the use of acupuncture as an adjunctive or stand-alone treatment for reducing VMSs and improving HRQOL outcomes, with the caveat that observed clinical benefit associated with acupuncture may be due, in part, or in whole to nonspecific effects. The safety of acupuncture in the treatment of VMSs has not been rigorously examined, but there is no clear signal for a significant potential for harm.

Reduction in Pain Medication Prescriptions and Self-Reported Outcomes Associated with Acupuncture in a Military Patient Population.

Background: Acupuncture is being offered to patients as part of routine medical care in selected military bases in the United States. There is little published information about the clinical outcomes associated with acupuncture in these clinical settings. Objective: The goal of this research was to assess clinical outcomes observed among adult patients who received acupuncture treatments at a United States Air Force medical center. Materials and Methods: This retrospective chart review was performed at the Nellis Family Medicine Residency in the Mike O'Callaghan Military Medical Center at Nellis Air Force Base in Las Vegas, NV. The charts were from 172 consecutive patients who had at least 4 acupuncture treatments within 1 year. The main outcome measures were prescriptions for opioid medications, muscle relaxants, benzodiazepines, and nonsteroidal anti-inflammatory drugs (NSAIDS) in the 60 days prior to the first acupuncture session and in the corresponding 60 days 1 year later; and Measure Yourself Medical Outcome Profile (MYMOP2) values for symptoms, ability to perform activities, and quality of life. Results: Opioid prescriptions decreased by 45%, muscle relaxants by 34%, NSAIDs by 42%, and benzodiazepines by 14%. MYMOP2 values decreased 3.50-3.11 (P < 0.002) for question 1, 4.18-3.46 (P < 0.00001) for question 3, and 2.73-2.43 (P < 0.006) for question 4. Conclusions: In this military patient population, the number of opioid prescriptions decreased and patients reported improved symptom control, ability to function, and sense of well-being after receiving courses of acupuncture by their primary care physicians.

Trajectories of response to acupuncture for menopausal vasomotor symptoms: the Acupuncture in Menopause study.

OBJECTIVE: To examine the trajectories of responses to acupuncture treatment for menopausal vasomotor symptoms (VMS) and the characteristics of women in each trajectory. METHODS: Two hundred nine perimenopausal and postmenopausal women aged 45 to 60 years experiencing at least four VMS per day were recruited and randomized to receive up to 20 acupuncture treatments within 6 months or to a waitlist control group. The primary outcome was percent change from baseline in the mean daily VMS frequency. Finite mixture modeling was used to identify patterns of percent change in weekly VMS frequencies over the first 8 weeks. The Freeman-Holton test and analysis of variance were used to compare characteristics of women in different trajectories. RESULTS: Analyses revealed four distinct trajectories of change in VMS frequency by week 8 in the acupuncture group. A small group of women (11.6%, n = 19) had an 85% reduction in VMS. The largest group (47%, n = 79) reported a 47% reduction in VMS frequency, 37.3% (n = 65) of the sample showed only a 9.6% reduction in VMS frequency, and a very small group (4.1%, n = 7) had a 100% increase in VMS. Among women in the waitlist control group, 79.5% reported a 10% decrease in VMS frequency at week 8. Baseline number of VMS, number of acupuncture treatments in the first 8 weeks, and traditional Chinese medicine diagnosis were significantly related to trajectory group membership in the acupuncture group. CONCLUSIONS: Approximately half of the treated sample reported a decline in VMS frequency, but identifying clear predictors of clinical response to acupuncture treatment of menopausal VMS remains challenging.

Role of Acupuncture in the Treatment or Prevention of Migraine, Tension-Type Headache, or Chronic Headache Disorders.

OBJECTIVE: To summarize the current evidence that evaluates the effectiveness of acupuncture for the treatment or prevention of migraine, tension-type headache, and chronic headache disorders. METHODS: Findings from selected systematic reviews and meta-analyses are summarized. RESULTS: Recently published systematic reviews and meta-analyses demonstrate that acupuncture is associated with improved clinical outcomes compared to routine care only, medical management, and sham acupuncture 2 months after randomization. The evidence in support of acupuncture's comparative effectiveness at longer follow-up periods is mixed. Cost effectiveness analyses conducted in the United Kingdom and Germany suggest that acupuncture is a cost-effective treatment option in those countries. There are few or no cost-effectiveness studies of acupuncture in the United States. DISCUSSION: This brief review of the current, published evidence does not include a discussion of potential risks or adverse events associated with acupuncture. There is also the question of the extent to which placebo effects might contribute to acupuncture's clinical effectiveness. From a purely comparative effectiveness perspective, however, the evidence from clinical trials and meta-analyses makes a compelling case in support of a potentially important role for acupuncture as part of a treatment plan for patients with migraine, tension-type headache, and several different types of chronic headache disorders.

An evidence map of yoga for low back pain.

OBJECTIVE: Yoga is being increasingly studied as a treatment strategy for a variety of different clinical conditions, including low back pain (LBP). We set out to conduct an evidence map of yoga for the treatment, prevention and recurrence of acute or chronic low back pain (cLBP). METHODS: We searched Medline, Cochrane Database of Systematic Reviews, EMBASE, Allied and Complementary Medicine Database and ClinicalTrials.gov for randomized controlled trials (RCT), systematic reviews or planned studies on the treatment or prevention of acute back pain or cLBP. Two independent reviewers screened papers for inclusion, extracted data and assessed the quality of included studies. RESULTS: Three eligible systematic reviews were identified that included 10 RCTs (n=956) that evaluated yoga for non-specific cLBP. We did not identify additional RCTs beyond those included in the systematic reviews. Our search of ClinicalTrials.gov identified one small (n=10) unpublished trial and one large (n=320) planned clinical trial. The most recent good quality systematic review indicated significant effects for short- and long-term pain reduction (n=6 trials; standardized mean difference [SMD] -0.48; 95% CI, -0.65 to -0.31; I(2)=0% and n=5; SMD -0.33; 95% CI, -0.59 to -0.07; I(2)=48%, respectively). Long-term effects for back specific disability were also identified (n=5; SMD -0.35; 95% CI, -0.55 to -0.15; I(2)=20%). No studies were identified evaluating yoga for prevention or treatment of acute LBP. CONCLUSION: Evidence suggests benefit of yoga in midlife adults with non-specific cLBP for short- and long-term pain and back-specific disability, but the effects of yoga for health-related quality of life, well- being and acute LBP are uncertain. Without additional studies, further systematic reviews are unlikely to be informative.
