RESUMO
BACKGROUND: Massage is widely used for neck pain, but its effectiveness remains unclear. OBJECTIVES: To assess the benefits and harms of massage compared to placebo or sham, no treatment or exercise as an adjuvant to the same co-intervention for acute to chronic persisting neck pain in adults with or without radiculopathy, including whiplash-associated disorders and cervicogenic headache. SEARCH METHODS: We searched multiple databases (CENTRAL, MEDLINE, EMBASE, CINAHL, Index to Chiropractic Literature, trial registries) to 1 October 2023. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing any type of massage with sham or placebo, no treatment or wait-list, or massage as an adjuvant treatment, in adults with acute, subacute or chronic neck pain. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. We transformed outcomes to standardise the direction of the effect (a smaller score is better). We used a partially contextualised approach relative to identified thresholds to report the effect size as slight-small, moderate or large-substantive. MAIN RESULTS: We included 33 studies (1994 participants analysed). Selection (82%) and detection bias (94%) were common; multiple trials had unclear allocation concealment, utilised a placebo that may not be credible and did not test whether blinding to the placebo was effective. Massage was compared with placebo (n = 10) or no treatment (n = 8), or assessed as an adjuvant to the same co-treatment (n = 15). The trials studied adults aged 18 to 70 years, 70% female, with mean pain severity of 51.8 (standard deviation (SD) 14.1) on a visual analogue scale (0 to 100). Neck pain was subacute-chronic and classified as non-specific neck pain (85%, including n = 1 whiplash), radiculopathy (6%) or cervicogenic headache (9%). Trials were conducted in outpatient settings in Asia (n = 11), America (n = 5), Africa (n = 1), Europe (n = 12) and the Middle East (n = 4). Trials received research funding (15%) from research institutes. We report the main results for the comparison of massage versus placebo. Low-certainty evidence indicates that massage probably results in little to no difference in pain, function-disability and health-related quality of life when compared against a placebo for subacute-chronic neck pain at up to 12 weeks follow-up. It may slightly improve participant-reported treatment success. Subgroup analysis by dose showed a clinically important difference favouring a high dose (≥ 8 sessions over four weeks for ≥ 30 minutes duration). There is very low-certainty evidence for total adverse events. Data on patient satisfaction and serious adverse events were not available. Pain was a mean of 20.55 points with placebo and improved by 3.43 points with massage (95% confidence interval (CI) 8.16 better to 1.29 worse) on a 0 to 100 scale, where a lower score indicates less pain (8 studies, 403 participants; I2 = 39%). We downgraded the evidence to low-certainty due to indirectness; most trials in the placebo comparison used suboptimal massage doses (only single sessions). Selection, performance and detection bias were evident as multiple trials had unclear allocation concealment, utilised a placebo that may not be credible and did not test whether blinding was effective, respectively. Function-disability was a mean of 30.90 points with placebo and improved by 9.69 points with massage (95% CI 17.57 better to 1.81 better) on the Neck Disability Index 0 to 100, where a lower score indicates better function (2 studies, 68 participants; I2 = 0%). We downgraded the evidence to low-certainty due to imprecision (the wide CI represents slight to moderate benefit that does not rule in or rule out a clinically important change) and risk of selection, performance and detection biases. Participant-reported treatment success was a mean of 3.1 points with placebo and improved by 0.80 points with massage (95% CI 1.39 better to 0.21 better) on a Global Improvement 1 to 7 scale, where a lower score indicates very much improved (1 study, 54 participants). We downgraded the evidence to low-certainty due to imprecision (single study with a wide CI that does not rule in or rule out a clinically important change) and risk of performance as well as detection bias. Health-related quality of life was a mean of 43.2 points with placebo and improved by 5.30 points with massage (95% CI 8.24 better to 2.36 better) on the SF-12 (physical) 0 to 100 scale, where 0 indicates the lowest level of health (1 study, 54 participants). We downgraded the evidence once for imprecision (a single small study) and risk of performance and detection bias. We are uncertain whether massage results in increased total adverse events, such as treatment soreness, sweating or low blood pressure (RR 0.99, 95% CI 0.08 to 11.55; 2 studies, 175 participants; I2 = 77%). We downgraded the evidence to very low-certainty due to unexplained inconsistency, risk of performance and detection bias, and imprecision (the CI was extremely wide and the total number of events was very small, i.e < 200 events). AUTHORS' CONCLUSIONS: The contribution of massage to the management of neck pain remains uncertain given the predominance of low-certainty evidence in this field. For subacute and chronic neck pain (closest to 12 weeks follow-up), massage may result in a little or no difference in improving pain, function-disability, health-related quality of life and participant-reported treatment success when compared to a placebo. Inadequate reporting on adverse events precluded analysis. Focused planning for larger, adequately dosed, well-designed trials is needed.

BACKGROUND: More than one in five patients who undergo treatment for breast cancer will develop breast cancer-related lymphedema (BCRL). BCRL can occur as a result of breast cancer surgery and/or radiation therapy. BCRL can negatively impact comfort, function, and quality of life (QoL). Manual lymphatic drainage (MLD), a type of hands-on therapy, is frequently used for BCRL and often as part of complex decongestive therapy (CDT). CDT is a fourfold conservative treatment which includes MLD, compression therapy (consisting of compression bandages, compression sleeves, or other types of compression garments), skin care, and lymph-reducing exercises (LREs). Phase 1 of CDT is to reduce swelling; Phase 2 is to maintain the reduced swelling. OBJECTIVES: To assess the efficacy and safety of MLD in treating BCRL. SEARCH METHODS: We searched Medline, EMBASE, CENTRAL, WHO ICTRP (World Health Organization's International Clinical Trial Registry Platform), and Cochrane Breast Cancer Group's Specialised Register from root to 24 May 2013. No language restrictions were applied. SELECTION CRITERIA: We included randomized controlled trials (RCTs) or quasi-RCTs of women with BCRL. The intervention was MLD. The primary outcomes were (1) volumetric changes, (2) adverse events. Secondary outcomes were (1) function, (2) subjective sensations, (3) QoL, (4) cost of care. DATA COLLECTION AND ANALYSIS: We collected data on three volumetric outcomes. (1) LE (lymphedema) volume was defined as the amount of excess fluid left in the arm after treatment, calculated as volume in mL of affected arm post-treatment minus unaffected arm post-treatment. (2) Volume reduction was defined as the amount of fluid reduction in mL from before to after treatment calculated as the pretreatment LE volume of the affected arm minus the post-treatment LE volume of the affected arm. (3) Per cent reduction was defined as the proportion of fluid reduced relative to the baseline excess volume, calculated as volume reduction divided by baseline LE volume multiplied by 100. We entered trial data into Review Manger 5.2 (RevMan), pooled data using a fixed-effect model, and analyzed continuous data as mean differences (MDs) with 95% confidence intervals (CIs). We also explored subgroups to determine whether mild BCRL compared to moderate or severe BCRL, and BCRL less than a year compared to more than a year was associated with a better response to MLD. MAIN RESULTS: Six trials were included. Based on similar designs, trials clustered in three categories.(1) MLD + standard physiotherapy versus standard physiotherapy (one trial) showed significant improvements in both groups from baseline but no significant between-groups differences for per cent reduction.(2) MLD + compression bandaging versus compression bandaging (two trials) showed significant per cent reductions of 30% to 38.6% for compression bandaging alone, and an additional 7.11% reduction for MLD (MD 7.11%, 95% CI 1.75% to 12.47%; two RCTs; 83 participants). Volume reduction was borderline significant (P = 0.06). LE volume was not significant. Subgroup analyses was significant showing that participants with mild-to-moderate BCRL were better responders to MLD than were moderate-to-severe participants.(3) MLD + compression therapy versus nonMLD treatment + compression therapy (three trials) were too varied to pool. One of the trials compared compression sleeve plus MLD to compression sleeve plus pneumatic pump. Volume reduction was statistically significant favoring MLD (MD 47.00 mL, 95% CI 15.25 mL to 78.75 mL; 1 RCT; 24 participants), per cent reduction was borderline significant (P=0.07), and LE volume was not significant. A second trial compared compression sleeve plus MLD to compression sleeve plus self-administered simple lymphatic drainage (SLD), and was significant for MLD for LE volume (MD -230.00 mL, 95% CI -450.84 mL to -9.16 mL; 1 RCT; 31 participants) but not for volume reduction or per cent reduction. A third trial of MLD + compression bandaging versus SLD + compression bandaging was not significant (P = 0.10) for per cent reduction, the only outcome measured (MD 11.80%, 95% CI -2.47% to 26.07%, 28 participants).MLD was well tolerated and safe in all trials.Two trials measured function as range of motion with conflicting results. One trial reported significant within-groups gains for both groups, but no between-groups differences. The other trial reported there were no significant within-groups gains and did not report between-groups results. One trial measured strength and reported no significant changes in either group.Two trials measured QoL, but results were not usable because one trial did not report any results, and the other trial did not report between-groups results.Four trials measured sensations such as pain and heaviness. Overall, the sensations were significantly reduced in both groups over baseline, but with no between-groups differences. No trials reported cost of care.Trials were small ranging from 24 to 45 participants. Most trials appeared to randomize participants adequately. However, in four trials the person measuring the swelling knew what treatment the participants were receiving, and this could have biased results. AUTHORS' CONCLUSIONS: MLD is safe and may offer additional benefit to compression bandaging for swelling reduction. Compared to individuals with moderate-to-severe BCRL, those with mild-to-moderate BCRL may be the ones who benefit from adding MLD to an intensive course of treatment with compression bandaging. This finding, however, needs to be confirmed by randomized data.In trials where MLD and sleeve were compared with a nonMLD treatment and sleeve, volumetric outcomes were inconsistent within the same trial. Research is needed to identify the most clinically meaningful volumetric measurement, to incorporate newer technologies in LE assessment, and to assess other clinically relevant outcomes such as fibrotic tissue formation.Findings were contradictory for function (range of motion), and inconclusive for quality of life.For symptoms such as pain and heaviness, 60% to 80% of participants reported feeling better regardless of which treatment they received.One-year follow-up suggests that once swelling had been reduced, participants were likely to keep their swelling down if they continued to use a custom-made sleeve.

BACKGROUND: The prevalence of mechanical neck disorders (MND) is known to be both a hindrance to individuals and costly to society. As such, massage is widely used as a form of treatment for MND. OBJECTIVES: To assess the effects of massage on pain, function, patient satisfaction, global perceived effect, adverse effects and cost of care in adults with neck pain versus any comparison at immediate post-treatment to long-term follow-up. SEARCH METHODS: We searched The Cochrane Library (CENTRAL), MEDLINE, EMBASE, MANTIS, CINAHL, and ICL databases from date of inception to 4 Feburary 2012. SELECTION CRITERIA: Studies using random assignment were included. DATA COLLECTION AND ANALYSIS: Two review authors independently conducted citation identification, study selection, data abstraction and methodological quality assessment. Using a random-effects model, we calculated the risk ratio and standardised mean difference. MAIN RESULTS: Fifteen trials met the inclusion criteria. The overall methodology of all the trials assessed was either low or very low GRADE level. None of the trials were of strong to moderate GRADE level. The results showed very low level evidence that certain massage techniques (traditional Chinese massage, classical and modified strain/counter strain technique) may have been more effective than control or placebo treatment in improving function and tenderness. There was very low level evidence that massage may have been more beneficial than education in the short term for pain bothersomeness. Along with that, there was low level evidence that ischaemic compression and passive stretch may have been more effective in combination rather than individually for pain reduction. The clinical applicability assessment showed that only 4/15 trials adequately described the massage technique. The majority of the trials assessed outcomes at immediate post-treatment, which is not an adequate time to assess clinical change. Due to the limitations in the quality of existing studies, we were unable to make any firm statement to guide clinical practice. We noted that only four of the 15 studies reported side effects. All four studies reported post-treatment pain as a side effect and one study (Irnich 2001) showed that 22% of the participants experienced low blood pressure following treatment. AUTHORS' CONCLUSIONS: No recommendations for practice can be made at this time because the effectiveness of massage for neck pain remains uncertain.As a stand-alone treatment, massage for MND was found to provide an immediate or short-term effectiveness or both in pain and tenderness. Additionally, future research is needed in order to assess the long-term effects of treatment and treatments provided on more than one occasion.

Massage is an increasingly popular complementary and alternative medicine modality used for a variety of conditions. Cochrane massage reviews are a gold mine of observations regarding the methodologic issues inherent in massage trials and have raised important questions, which can be used to guide future research. Among the research issues raised in Cochrane reviews are questions about combination trials, practitioner qualifications, adequate doses, and appropriate control groups. This article summarizes these key research issues.

PURPOSE: Assess the effectiveness of acupuncture-point stimulation on acute and delayed chemotherapy-induced nausea and vomiting in cancer patients. MATERIALS AND METHODS: Randomized trials of acupuncture-point stimulation by needles, electrical stimulation, magnets, or acupressure were retrieved. Data were provided by investigators of the original trials and pooled using a fixed-effects model. RESULTS: Eleven trials (N = 1,247) were pooled. Overall, acupuncture-point stimulation reduced the proportion of acute vomiting (relative risks [RR] = 0.82; 95% CI, 0.69 to 0.99; P = .04), but not the mean number of acute emetic episodes or acute or delayed nausea severity compared with controls. By modality, stimulation with needles reduced the proportion of acute vomiting (RR = 0.74; 95% CI, 0.58 to 0.94; P = .01), but not acute nausea severity. Electroacupuncture reduced the proportion of acute vomiting (RR = 0.76; 95% CI, 0.60 to 0.97; P = .02), but manual acupuncture did not; delayed symptoms were not reported. Acupressure reduced mean acute nausea severity (standardized mean difference = -0.19; 95% CI, -0.38 to -0.01; P = .03) and most severe acute nausea, but not acute vomiting or delayed symptoms. Noninvasive electrostimulation showed no benefit for any outcome. All trials used concomitant pharmacologic antiemetics, and all, except electroacupuncture trials, used state-of-the-art antiemetics. CONCLUSION: This review complements data on postoperative nausea and vomiting, suggesting a biologic effect of acupuncture-point stimulation. Electroacupuncture has demonstrated benefit for chemotherapy-induced acute vomiting, but studies with state-of-the-art antiemetics as well as studies for refractory symptoms are needed to determine clinical relevance. Acupressure seems to reduce chemotherapy-induced acute nausea severity, though studies did not involve a placebo control. Noninvasive electrostimulation seems unlikely to have a clinically relevant impact when patients are given state-of-the-art pharmacologic antiemetic therapy.

BACKGROUND: Systematic reviewers generally evaluate randomized controlled trials (RCTs) based on the published reports. We evaluated whether the description of methods in the published reports is an accurate and complete reflection of study procedures used. METHODS: The authors of 51 RCTs included in a systematic review of acupuncture for chronic pain were sent a brief survey that included questions related to the following three important study quality dimensions: (1) generation of allocation sequence, (2) allocation concealment, and (3) blinding of outcomes assessor. RESULTS: We received 35 of 51 responses for an overall response rate of 68.6%. Of 35 studies described as randomized in published reports, associated survey responses indicated that four actually used quasi-randomized methods. Among published reports with missing information on these quality dimensions, 27 of 32 studies used adequate methods for the generation of allocation sequence, 13 of 34 used adequate allocation concealment and 2 of 10 were blinded, according to survey responses. Survey responses generally confirmed information about randomization and blinding already described in investigators' RCT publications. CONCLUSION: Surveying RCT investigators uncovered some information about study quality dimensions not described in published reports.

The objective of this overview is to summarize existing knowledge about the effects of acupuncture-point stimulation on nausea and vomiting. Systematic reviews on postoperative nausea and vomiting, chemotherapy-induced nausea and vomiting, and pregnancy-related nausea and vomiting exist. Several randomised trials, but no reviews, exist for motion sickness. For postoperative nausea and vomiting, results from 26 trials showed acupuncture-point stimulation was effective for both nausea and vomiting. For chemotherapy-induced nausea and vomiting, results of 11 trials differed according to modality with acupressure appearing effective for first-day nausea, electroacupuncture appearing effective for first-day vomiting, and noninvasive electrostimulation appearing no more effective than placebo for any outcome. For pregnancy-related nausea and vomiting, results were mixed. Experimental studies showed effects of P6-stimulation on gastric myoelectrical activity, vagal modulation and cerebellar vestibular activities in functional magnetic resonance imaging. There is good clinical evidence from more than 40 randomised controlled trials that acupuncture has some effect in preventing or attenuating nausea and vomiting. A growing number of experimental studies suggest mechanisms of action.

BACKGROUND: In 1998, the National Institutes of Health Consensus Statement on Acupuncture concluded that promising results have emerged showing the efficacy of acupuncture in adult postoperative and chemotherapy induced nausea and vomiting. The acupuncture point, P6 had been the point used in most of the trials. OBJECTIVES: To summarize Cochrane systematic reviews assessing P6 stimulation for nausea and vomiting. RESULTS: Reviews were found on postoperative sickness, chemotherapy-induced nausea and vomiting, and pregnancy-related nausea and vomiting. Results for postoperative nausea and vomiting show the most consistent results with 26 trials and more than 3000 patients showing the superiority of real P6 stimulation over sham for both adults and children and for both nausea and vomiting. Pooled data of trials including different antiemetics showed that P6 stimulation seems to be superior to antiemetic medication for nausea and equivalent for vomiting. P6 stimulation was similarly effective across the different methods of stimulation, both invasive or noninvasive. Results for chemotherapy-induced nausea and vomiting showed 11 trials and over 1200 patients. Electroacupuncture, but not manual acupuncture, was beneficial for first-day vomiting. Acupressure was effective for first-day nausea but not vomiting. Wristwatch-like electrical devices were not effective for any outcome. Results for pregnancy-related nausea and vomiting comprised six trials and approximately 1150 patients. Results were mixed with some trials showing positive and other trials equivocal results with no favor to a certain kind of method. CONCLUSIONS: P6 stimulation may be beneficial for various conditions involving nausea and vomiting. The added value to modern antiemetics remains unclear. In patients on chemotherapy, future research should focus on patients for whom the problems are refractory. The next steps in research should include investigating whether acupuncture points added to P6 or individualizing treatment based on a Traditional Chinese Medicine diagnosis increases treatment effectiveness. It would also be worthwhile to identify predictors of response across the different conditions so that the individual patients can optimize acupuncture point therapy.

In the current issue of the Cochrane Library (Issue 3, 2004), there are more than 25 systematic reviews addressing the use of vitamins in the prevention or treatment of disease. Vitamins have been a mainstay of health since their discovery in the early 1900s, so a question arises as to when using vitamins is considered complementary as opposed to conventional medical practice. Complementary or alternative vitamin use encompasses those uses that are outside of accepted medical practice. The use of vitamin C to prevent scurvy is accepted medical practice. The use of vitamin C as a therapeutic adjunct to asthma is not. This paper summarizes 15 Cochrane systematic reviews on the complementary use of vitamins for an array of conditions including the common cold, Alzheimer's disease, asthma, chemotherapy-induced mucositis, and depression.

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. Our aim was to assess the effectiveness of acupuncture as a treatment for chronic pain within the context of the methodological quality of the studies. MEDLINE (1966-99), two complementary medicine databases, 69 conference proceedings, and the bibliographies of other articles and reviews were searched. Trials were included if they were randomized, had populations with pain longer than three months, used needles rather than surface electrodes, and were in English. Data were extracted by two independent reviewers using a validated instrument. Inter-rater disagreements were resolved by discussion. Fifty one studies met inclusion criteria. Clinical heterogeneity precluded statistical pooling. Results were positive in 21 studies, negative in 3 and neutral in 27. Three fourths of the studies received a low-quality score and low-quality trials were significantly associated with positive results (P=0.05). High-quality studies clustered in designs using sham acupuncture as the control group, where the risk of false negative (type II) errors is high due to large sample size requirements. 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.

There are more than 20 completed Cochrane systematic reviews on botanical medicine presently published in the Cochrane Library. There are more than 40 that are planned or in progress. It is an opportune time to explore the information needs of readers of botanical systematic reviews and how those needs can be met better by Cochrane systematic reviews. It is proposed that Cochrane systematic reviews focus not only on efficacy but also on expanded safety and quality. Expanded safety refers not only to the occurrence of adverse events but also the contraindications for use such as drug-herb interactions or allergies to products. Quality pertains to whether or not there was a method of standardizing active ingredients in trials and methods for minimizing risks of contamination. Because there are no package inserts to accompany herbal products as there are for drugs, Cochrane systematic reviews offer the ideal forum to present this much-needed information on expanded safety and quality.

Courses in complementary and alternative medicine (CAM) are increasing in medical schools in the United States and, currently, approximately two thirds of U.S. medical schools offer at least one such course. As these courses grow in popularity, however, concerns are also growing that these courses lack an evidence-based perspective. We propose that one interesting and easy way to bring an evidence-based perspective to the CAM classroom is to utilize the Cochrane Electronic Library (CLIB), which is available in many medical libraries, as a teaching tool. The CLIB currently houses more than 80 CAM-related, full-text systematic reviews and approximately 5000 CAM-related clinical trials, making it a valued resource for people who seek CAM evidence. Moreover, the CLIB commitment to publishing reviews regardless of the results make it a resource where one can find reviews concluding there is strong evidence of benefit or no evidence of benefit. In addition to the access to CAM evidence which the CLIB provides, students can learn basic critical appraisal skills by learning the rationale behind Cochrane systematic reviews. A survey of CAM course directors, however, shows that almost one half of these directors have never used the CLIB. For those who have never used the CLIB, this editorial explains the four main databases within the CLIB and presents ideas for using them in CAM school courses.

STUDY DESIGN: Systematic review. OBJECTIVE: To assess the effects of massage on pain, function, patient satisfaction, cost of care, and adverse events in adults with neck pain. SUMMARY OF BACKGROUND DATA: Neck pain is common, disabling, and costly. Massage is a commonly used modality for the treatment of neck pain. METHODS: We searched several databases without language restriction from their inception to September 2004. We included randomized and quasirandomized trials. Two reviewers independently identified studies, abstracted data, and assessed quality. We calculated the relative risks and standardized mean differences on primary outcomes. Trials could not be statistically pooled because of heterogeneity in treatment and control groups. Therefore, a levels-of-evidence approach was used to synthesize results. RESULTS: Overall, 19 trials were included, with 12/19 receiving low-quality scores. Descriptions of the massage intervention, massage professional's credentials, or experience were frequently missing. Six trials examined massage as a stand-alone treatment. The results were inconclusive. Results were also inconclusive in 14 trials that used massage as part of a multimodal intervention because none were designed such that the relative contribution of massage could be ascertained. CONCLUSIONS: No recommendations for practice can be made at this time because the effectiveness of massage for neck pain remains uncertain. Pilot studies are needed to characterize massage treatment (frequency, duration, number of sessions, and massage technique) and establish the optimal treatment to be used in subsequent larger trials that examine the effect of massage as either a stand-alone treatment or part of a multimodal intervention. For multimodal interventions, factorial designs are needed to determine the relative contribution of massage. Future reports of trials should improve reporting of the concealment of allocation, blinding of outcome assessor, adverse events, and massage characteristics. Standards of reporting for massage interventions, similar to Consolidated Standards of Reporting Trials, are needed. Both short and long-term follow-up are needed.
