ABSTRACT This is the protocol for a review and there is no abstract. The objectives are as follows: The objectives of this systematic review are to determine the effects of acupuncture for (sub)acute non-specific low-back pain compared to no treatment, placebo/sham acupuncture or other sham procedures, other therapies, the addition of acupuncture to other therapies, and between various techniques of acupuncture.
BACKGROUND
quently, the therapeutic management of (sub) acute low-back pain varies widely.
Description of the condition
Description of the intervention
Low-back pain is a major health problem among western industrialized countries, and a major cause of medical expenses, absenteeism and disablement (Deyo 2006). Although low-back pain is usually a self-limiting and benign disease (Waddell 1987), a large variety of therapeutic interventions are available to treat it (Haldeman 2008). However, the effectiveness of most of these interventions has not been convincingly demonstrated and conse-
Acupuncture is one of the oldest forms of therapy and has its roots in ancient Chinese philosophy. Traditional acupuncture is based on a number of philosophical concepts, one of which postulates that any manifestation of disease is considered a sign of imbalance between the Yin and Yang forces within the body. In classical acupuncture theory, it is believed that all disorders are reflected at specific points, either on the skin surface or just below it. Vital en-

ergy (qi) circulates throughout the body along the so-called meridians, which have either Yin or Yang characteristics. An appropriate choice of the 361 classical acupuncture points located on these twelve meridians for needling is believed to restore the balance in the body. When the needles have been placed successfully, the patient is supposed to experience a sensation known as de qi (in some schools of traditional acupuncture). De qi has been defined as a subjective feeling of fullness, numbness, tingling, and warmth, with some local soreness and a feeling of distension around the acupuncture point. There is no consensus among acupuncturists about the necessity of reaching de qi for acupuncture to be effective (Hui 2007). Since acupuncture disseminated to the west several hundred years ago, many different styles of acupuncture have evolved, including Japanese Meridian Therapy, French Energetic Acupuncture, Korean Constitutional Acupuncture and Lemington Five Element Acupuncture. While these are similar to traditional acupuncture, they each have distinct characteristics. In recent decades, acupuncture has expanded to include micro-system acupuncture such as ear (auricular) acupuncture, scalp (head) acupuncture, hand acupuncture, and foot acupuncture (Lao 1996). Modern acupuncturists use not only traditional meridian acupuncture points, but also non-meridian or extra-meridian acupuncture points, which are fixed points that are not necessarily associated with meridians. Acupuncture commonly includes manual stimulation of the needles, but various adjuncts are often used, including electroacupuncture (in which an electrical stimulator is connected to the acupuncture needle), injection acupuncture (herbal extracts injected into acupuncture points), heat lamps, and acupuncture with moxibustion (the moxa herb, Artemisia vulgaris, is burned at the handle of the needle for heat stimulation) (Lao 1996).
How the intervention might work It is still unclear what exact mechanisms underlie the action of acupuncture. Western scientific research has proposed mechanisms for the effect of acupuncture on pain relief. It has been suggested that the action of acupuncture might follow the principles of the gate control theory of pain. One type of sensory input (lowback pain) could be inhibited in the central nervous system by another type of input (needling). Another theory, the diffuse noxious inhibitory control (DNIC) (White 2006), implies that noxious stimulation of heterotopic body areas modulates the pain sensation originating in areas where a subject feels pain. There is also some evidence that acupuncture may stimulate the production of endorphins, serotonin and acetylcholine within the central nervous system, enhancing analgesia (Stux 2003). Other theories of acupuncture analgesia are based on neuromodulation of the central nervous system (Audette 2004). These are supported by human brain f-MRI studies (Hui 2010). A recent systematic review of the physiological rational of acupuncture identified 76 clinical trials. Among these, 33 proposed a neurochemical mechanism; two,
segmental nervous system effects; six, autonomic nervous system regulation; three, local effects; five, effects on brain function; and five, other effects (Moffet 2006). It has also been suggested that both specific and non-specific factors may play a role in the effectiveness of acupuncture (Liu 2009). Needle insertion into specific sites on the body acts on expectation mechanisms via attentional mechanisms, thus working through potentiation and modulation of expectation activated opioid systems (Liu 2009).
Why it is important to do this review The effectiveness of acupuncture in the treatment of (sub)acute low-back pain has been systematically reviewed before (van Tulder 1999; van Tulder 1999a; Furlan 2005; Furlan 2005a) with inconclusive results due to the paucity and high risk of bias of the included studies. Due to the increasing number of studies of acupuncture for various types of back pain, we have decided to present results in separate reviews for three types of back pain: acute non-specific back pain, chronic non-specific back pain (Sherman 2011), and back pain attributed to underlying presumptive etiology (Ammendolia 2011). This is an updated review of all available scientific evidence, including evidence from Chinese, Korean and Japanese trials, on the effectiveness of acupuncture for (sub) acute non-specific low-back pain.
OBJECTIVES The objectives of this systematic review are to determine the effects of acupuncture for (sub)acute non-specific low-back pain compared to no treatment, placebo/sham acupuncture or other sham procedures, other therapies, the addition of acupuncture to other therapies, and between various techniques of acupuncture.
METHODS
Criteria for considering studies for this review
Types of studies We will follow the methodology recommended in the Cochrane handbook (Higgins 2011) and by the Cochrane Back Review Group (Furlan 2009). We will only include randomised controlled trials (RCTs), with no language restriction, in this Cochrane systematic review.

Types of participants We will include adults (>18 years) with (sub)acute non-specific low-back pain. (Sub)acute is defined as pain duration less than 12 weeks. We will exclude studies that include a mixed population with (sub)acute and chronic non-specific low-back pain where the results of acupuncture for (sub)acute pain cannot be extracted separately. When the duration of low-back pain is not reported in the manuscript, we will attempt to contact the authors to obtain more information, but if we cannot obtain the response, we will exclude the study. Although some studies do not exclusively limit the study population to patients with non-specific symptoms, we will include studies if the majority (>50%) of the patients had non-specific low-back pain according to the predefined criteria. We will exclude RCTs that included subjects with low-back pain caused by specific etiological entities such as infection, metastatic diseases, neoplasm, osteoarthritis, rheumatoid arthritis or fractures. We will also exclude low-back pain during pregnancy and post-partum. Chronic non-specific low-back pain (Sherman 2011) and lowback pain attributed to underlying presumptive etiology ( Ammendolia 2011) will be the subjects of two other Cochrane Reviews conducted for the Cochrane Back Review Group. Types of interventions In this review, we will include articles that evaluate acupuncture treatments that involve needling. Articles that involve dryneedling for low-back pain attributed to myofascial pain syndrome will be included in another Cochrane review of low-back pain attributed to an underlying presumptive etiology (Ammendolia 2011). We will include studies in which “the diagnosis was made using traditional acupuncture theory and the needles were inserted in classical meridian points, ear points, extra points or Ah-shi points (painful points)’, Regardless of the source of stimulation (e.g., manual, heat by moxa or electrical stimulation). We will exclude studies in which the acupuncture treatment did not involve needling, such as acupressure or laser acupuncture. The control interventions will be: no treatment, placebo/sham acupuncture or other sham procedures, and other therapeutic interventions. We will also include trials which test the effectiveness of acupuncture as an adjunct treatment to other therapies compared to other therapies and trials comparing two techniques of acupuncture. Types of outcome measures We will include RCTs that used at least one of the four outcome measures considered to be important in the field of low-back pain: 1. pain intensity (e.g., visual analogue scale (VAS)) 2. back-specific functional status (e.g., Roland Morris Disability Scale, Oswestry Disability Scale) 3. global measure of improvement or recovery (e.g., overall improvement, proportion of patients recovered, subjective improvement of symptoms)
4. work-relevant outcomes (e.g., return-to-work status, number of days off work, productivity, etc).
Primary outcomes
The primary outcomes for this review will be pain and back-specific functional status.
Secondary outcomes
Secondary outcomes will be global measures of improvement, work-relevant outcomes, and complications
Search methods for identification of studies In the previous review (Furlan 2005), we updated the literature from 1966 until February 2003 using the following databases and strategies: 1. CENTRAL, (The Cochrane Library, 2003, issue 1); 2. MEDLINE (OVID) (see Appendix 1 for strategy); 3. EMBASE (OVID) (see Appendix 2 for strategy); 4. The Chinese Cochrane Centre Trials Registry (in February 2003); 5. A database search of controlled clinical trials published in Japan, using ”Igaku Chuo Zasshi“ (Japana Centra Revuo Medicina) web version (between 1987 - February 2003); 7. Reference lists in review articles and trials retrieved; and 8. Personal communication with experts in the field. Electronic searches For this updated review, we will use the following strategies. 1. Researchers at the University of Ottawa - Evidence-based Practice Centre (UO-EPC) updated the literature searches to February 2010 as part of the CAM BACK II report for the NCCAM (NIH) (Furlan 2010): • Electronic search strategies were developed and tested through an iterative process by an experienced medical information specialist in consultation with the UO-EPC team. • The following databases were searched: MEDLINE; the Cochrane Library including CENTRAL, Cochrane Database of Systematic Reviews, DARE, HTA, NHSEED; EMBASE; CINAHL; AMED; and EBM Reviews ACP Journal Club. Specialized CAM databases were also searched, including the Index to Chiropractic Literature (ILC); Acubriefs; Complementary and Alternative Medicine (NZ); and the LILACS Database. Several of these databases provided extensive coverage of foreign (e.g., Asian, South American) language materials. • Strategies utilized a combination of controlled vocabulary and keywords. (See Appendix 3 for full search strategies)

• There were no language or date restrictions on any of the searches; animal studies were excluded. • Additional references were also sought through handsearching the bibliographies of relevant items. • Grey (unpublished) literature was identified by searching the websites of relevant specialty societies and organizations, Health Technology Agencies (HTAs), economic research institutions, guideline collections, trial registries, and conferences. (See Appendix 4 for full search strategies) 2. One member of our team (BCS) searched six Korean medical databases for trials published in Korea to March 2010, i.e. DBPIA, Korea Institute of Science and Technology Information, The National Library of Korea, Korean traditional knowledge portal, OASIS and KoreaMed. Another member of our team (IW) will update the searches in the Japanese databases up to the present. 3. The Trials Search Co-ordinator of the Cochrane Back Review Group will search CENTRAL, MEDLINE, EMBASE, and CINAHL, using the search strategies shown in Appendix 1 and Appendix 2 from January 2010 to the present.
Searching other resources We will review reference lists in review articles and trials.
Data collection and analysis
Selection of studies For this updated review, we will use a three-step study selection process: 1) This step has already occurred: The team at Chalmers Institute (FY and AT) generated the electronic search strategies and downloaded the citations into Systematic Review Software (SRS). Two review authors (FY and AT) independently reviewed the information to identify trials that potentially met the inclusion criteria. Full articles describing these trials were obtained and the same two review authors independently applied the selection criteria to the studies. Consensus was used to solve disagreements concerning the final inclusion of RCTs and a third review author was consulted when disagreements persisted. The authors of recent original studies were contacted to obtain more information when needed. 2) One member of our team (BCS) will select the articles meeting inclusion criteria from the searches in the Korean databases, and another member (IW) will select the articles in the Japanese databases. In each case, these review authors will find a second reviewer who will independently assess the studies for inclusion/ exclusion and will discuss to reach consensus. 3) The Back Group Trials Search Co-ordinator will do a preliminary screening of the Titles and Abstracts identified in the other
searches and will send them to the contact author. Two review authors will apply the inclusion criteria and select studies for inclusion in this updated review.
Data extraction and management Two review authors will independently extract the data on the study characteristics, funding, ethics, study population, interventions, analyses and outcomes. The team at Chalmers Institute used SRS (Systematic Reviews Software, TrialStaT) for this purpose. Our team will use Microsoft Excel for data extraction. We will contact the authors of recent studies (published in the past five years) to obtain more information when needed.
Adequacy of treatment
BCS, IW and an acupuncturist supervised by LXL will judge the adequacy of treatment using the STRICTA recommendations (MacPherson 2010): 1) Choice of acupoints, 2) Number of sessions, 3) Needling technique and 4) Acupuncturist experience. The control groups will also be judged for 1) appropriateness of sham/placebo intervention and 2) adequate number of sessions/ dose. For each of these treatment components, they will rate adequacy on a three-point scale from 1=not at all appropriate to 3= most appropriate.
Assessment of risk of bias in included studies We will use the 12-item criteria list recommended by the Cochrane Back Review Group plus one item “Other Sources of Bias” to assess the risk of bias (Boutron 2005; Furlan 2009; van Tulder 2003; Appendix 5). For each study, we will rate a criterion as ”low risk“, ”high risk“ or ”unclear“ to identify its performance against the criteria and record our decision in the Risk of Bias Table. Each study will be classified as having low or high risk of bias depending on the number of criteria met: studies fulfilling at least six criteria and not having a fatal flaw will be judged as having ‘low risk of bias’. Studies with a fatal flaw, or those meeting fewer than six criteria will be judged as having ‘high risk of bias’. Examples of fatal flaws are 1) an unacceptably high drop-out rate (greater than 50% at the first and subsequent follow-up measurements); 2) an unacceptably low adherence rate; or 3) statistically and clinically-relevant important baseline differences for one or more primary outcomes (i.e. pain, functional status) indicating unsuccessful randomisation.
Measures of treatment effect The primary analyses, decided a priori, will be: • acupuncture compared to no treatment, placebo / sham acupuncture or other sham procedures • acupuncture compared to another intervention

• acupuncture added to an intervention compared to the same intervention without acupuncture. We will consider any other comparisons as secondary analysis: • comparison between different acupuncture techniques We will plot the results of each RCT as point estimates, i.e., relative risks (RR) with corresponding 95% confidence interval (CI) for dichotomous outcomes, mean and standard deviation (SD) for continuous outcomes, or other data types as reported by the authors of the studies. When the results cannot be plotted, they will be described in the table of Characteristics of included studies. For continuous measures, we will give preference to analysing the results with mean differences (MD) when the same instruments are used, otherwise, we will use standardized mean differences (SMD) for effect sizes.
Dealing with missing data When there are insufficient data to enter in the meta-analysis (even after contacting the authors), we will report the results qualitatively in the table of Characteristics of Included studies and in the Summary of findings tables. Assessment of heterogeneity We will assess the studies first for clinical homogeneity with respect to the duration of the disorder, types of acupuncture, control group, outcomes measures and timing of follow-up. Clinically heterogeneous studies will be not combined in the analysis, but separately described. For studies judged as clinically homogeneous, we will test statistical heterogeneity with the Q test (Chi-statistic) and I². We will pool clinically and statistically homogeneous studies using the fixed-effect model. We will pool clinically homogeneous and statistically heterogeneous studies using the random-effects model.
Unit of analysis issues We will group the results according to the following study characteristics:
Assessment of reporting biases This is described under assessment of risk of bias (Appendix 5). Data synthesis
1) Control group:
a. no treatment b. placebo or sham acupuncture c. other interventions d. another techniques of acupuncture
2) Outcome measures:
a. Pain b. Global measure c. Back-specific functional status d. Work-relevant outcomes e. Physical examination f. Generic health status, other symptoms, medication use, etc g. Complications
3) Timing of follow-up:
a. immediately after the end of the sessions - up to one week after the end of the sessions b. short-term follow-up - between one week and three months after the end of the sessions c. intermediate-term follow-up - between three months and one year after the end of the sessions d. long-term follow-up - one year or longer after the end of the sessions
We will assess the overall strength of evidence using the grading system approach suggested by the Evidence-based Practice Center (EPC) program of the U.S. Agency for Healthcare Research and Quality (AHRQ) (Owens 2010). This system is largely based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) (Guyatt 2008) working group approach (Atkins 2004) and is similar to the system recommended by the Cochrane Back Review Group (Furlan 2009). The evidence grading method consists of four major domains: 1) risk of bias (aggregate measure of the overall quality or degree of bias of study/studies for a given outcome or comparison). This criteria will be downgraded when >25% of the participants were from studies with a high risk of bias (RoB) 2) consistency (the degree to which results of studies for a given outcome or comparison are uniform in terms of effect direction and statistical significance). Results will be considered consistent when I² < 50%; or in the absence of meta-analysis, all trials show statistically significant or non-significant effects in the same direction. 3) directness (ultimate health outcomes versus surrogate outcomes). Clinical outcomes such as pain and back-specific disability or function will be considered ‘direct evidence’. Other measures, such as quality of life, proportion of subjects who improved, time to (or duration of ) analgesic effect, use of analgesics, utilization of conventional healthcare system (e.g., general practitioner visits, imaging studies), sick leave (e.g., length, proportion of subjects), and proportion of subjects cured will be considered ‘indirect evidence’.

4) precision (the degree of variability/uncertainty around the pooled effect estimate). The pooled estimate with relatively narrow range of effect sizes (95% CIs) with clear direction leading to a clinically uniform conclusion will be considered ‘precise evidence’. We will not downgrade the quality of the evidence based on this domain simply due to the absence of meta-analysis because this might not be appropriate and available at all times. In addition, the evidence will be considered imprecise when the total number of participants are less than 400 (continuous outcomes) or 300 (dichotomous outcomes). The overall quality of the evidence for a given outcome will derive from the assessment of the four domains described above. Depending on ratings, the quality of the evidence will be high, moderate, low, or insufficient (Appendix 6). The absence of evidence will be graded as ‘insufficient’. Subgroup analysis and investigation of heterogeneity We do not plan any subgroup analyses for this review.
To determine if there is publication bias, we will construct funnel plots when at least 10 studies are available for the meta-analysis (Sutton 2000).
Sensitivity analysis For the primary outcomes, when we find comparisons that include 10 or more trials with mixed risks of bias (low and high), we will conduct a sensitivity analysis including only trials with a low risk of bias to check if this would change the main conclusions.

Appendix 5. Sources of Risk of Bias 1. Random sequence generation. (selection bias) There is a low risk of selection bias if a random (unpredictable) assignment sequence was used. Examples of low risk methods are: referring to a random number table, using a computer random number generator, coin tossing, shuffling cards or envelopes, throwing dice, drawing of lots, minimization (minimization may be implemented without a random element, and this is considered to be equivalent to being random). Examples of high risk methods are: alternation, birth date, social insurance/security number, date in which they are invited to participate in the study, or hospital registration number 2. Allocation concealment. (selection bias) There is a low risk of selection bias if the assignment was generated by an independent person not responsible for determining the eligibility of the patients. This person had no information about the persons included in the trial, no influence on the assignment sequence or eligibility of the patient, and could not foresee assignment because one of the following, or an equivalent method, was used to conceal allocation: central allocation (including telephone, web-based, and pharmacy-controlled, randomization); sequentially numbered drug containers of identical appearance; sequentially numbered, opaque, or sealed envelopes. Examples of high risk methods are: using an open random allocation schedule (e.g. a list of random numbers), assignment envelopes were used without appropriate safeguards (e.g. if envelopes were unsealed or non-opaque or not sequentially numbered), alternation or rotation, date of birth, case record number, or other explicitly unconcealed procedure. Knowledge of the allocated interventions was adequately prevented during the study. (performance bias) 3. Blinding of participants. (performance bias) There is a low risk of performance bias if the index and control groups were indistinguishable for the patients, the success of blinding was tested among the patients and it was successful, or the outcome measurements were not likely to be influenced by lack of blinding. 4. Blinding of personnel. (performance bias) There is a low risk of performance bias if the index and control groups were indistinguishable for the care providers, the success of blinding was tested among the care providers and it was successful, or the outcome measurements were not likely to be influenced by lack of blinding.

5. Blinding of outcomes assessment. (detection bias) Adequacy of blinding should be assessed for the primary outcomes. There is low risk of detection bias if the success of blinding was tested among the outcome assessors and it was successful, or: • for patient-reported outcomes in which the patient was the outcome assessor (e.g., pain, disability): there is a low risk of bias for outcome assessors if there is a low risk of bias for participant blinding. • for outcome criteria assessed during scheduled visit and that supposes a contact between participants and outcome assessors (e.g., clinical examination): there is a low risk of bias for patients and the treatment or adverse effects of the treatment could not be noticed during clinical examination. • for outcome criteria that are clinical or therapeutic events that will be determined by the interaction between patients and care providers (e.g., treatment failure), in which the care provider is the outcome assessor: there is a low risk of bias for outcome assessors if there is a low risk of bias for care providers. • for outcome criteria that are assessed from data from medical forms: there is a low risk of bias if the treatment or adverse effects of the treatment could not be noticed in the extracted data. Incomplete outcome data. (attrition bias) 6. The drop-out rate was described and acceptable. The number of participants who were included in the study but did not complete the observation period or were not included in the analysis must be described and reasons given. There is a low risk of attrition bias if there were no missing data, reasons for missing outcome data were unlikely to be related to the true outcome (for survival data, censoring unlikely to be introducing bias), missing outcome data were balanced in numbers, with similar reasons for missing data across groups, the percentage of withdrawals and drop-outs did not exceed 20% for short-term follow-up and 30% for long-term follow-up and did not lead to substantial bias (Note: these percentages are arbitrary, not supported by literature). For dichotomous outcome data, the proportion of missing outcomes compared with the observed event risk was not enough to have a clinically relevant impact on the intervention effect estimate; for continuous outcome data, the plausible effect size (difference in means or standardized difference in means) among missing outcomes was not enough to have a clinically relevant impact on observed effect size, or missing data were imputed using appropriate methods (Note: if drop-outs are very large, even imputation using “acceptable” methods may still suggest a high risk of bias) 7. All randomised participants were analysed in the group to which they were allocated. (attrition bias) There is low risk of attrition bias if all randomised patients were reported/analyzed in the group to which they were allocated by randomisation for the most important moments of effect measurement (minus missing values), regardless of non-compliance and cointerventions. 8. Selective reporting. (reporting bias) There is low risk of reporting bias if the results from all pre-specified outcomes have been adequately reported in the published report of the trial. This information is either obtained by comparing the protocol and the report, or in the absence of the protocol, assessing that the published report includes enough information to make this judgment. There is a high risk of reporting bias if one or more outcomes of interest is not measured or reported as pre-specified, is not reported or is reported incompletely so that data cannot be entered in a meta-analysis; the study report fails to include results for a key outcome that would be expected to have been reported for such a study. Other sources of potential bias: 9. Important prognostic indicators at baseline. There is low risk of bias if groups are similar at baseline for demographic factors, duration and severity of complaints, percentage of patients with neurological symptoms, or value of main outcome measure(s). 10. Co-interventions. There is low risk of bias if there were no co-interventions or they were similar between the index and control groups. 11. Compliance. There is low risk of bias if compliance with the interventions was acceptable, based on the reported intensity, duration, number and frequency of sessions for both the index and control intervention(s). For example, since physiotherapy treatment is usually administered over several sessions, it is important to assess how many sessions each patient attended. For single-session interventions (e.g., surgery), this item is irrelevant. 12. Timing of the outcome assessment across groups. There is low risk of bias if all important outcome assessments for all intervention groups were measured at the same time. 13. Other bias. There is a low risk of bias if the study appears to be free of other sources of bias not addressed elsewhere (e.g., study funding).
