Abstract
BACKGROUND Previous systemic reviews have examined the efficacy of individual therapeutic agents, but which type of treatment is superior to another has not been pooled or analyzed. The objective of the current study was to compare the clinical effectiveness of epidural steroid injection (ESI) versus conservative treatment for patients with lumbosacral radicular pain. METHODS A systematic search was conducted with MEDLINE, EMBASE, and CENTRAL databases with a double-extraction technique for relevant studies published between 2000 and January 10, 2019. The randomized controlled trials which directly compared the efficacy of ESI with conservative treatment in patients with lumbosacral radicular pain were included. Outcomes included visual analog scale, numeric rating scale, Oswetry disability index, or successful events. Two reviewers extracted data and evaluated the methodological quality of papers using the Cochrane Collaboration Handbook. A meta-analysis was performed using Revman 5.2 software. The heterogeneity of the meta-analysis was also assessed. RESULTS Of 1071 titles initially identified, 6 randomized controlled trials (249 patients with ESI and 241 patients with conservative treatment) were identified and included in this meta-analysis. The outcome of the pooled analysis showed that ESI was beneficial for pain relief at short-term and intermediate-term follow-up when compared with conservative treatment, but this effect was not maintained at long-term follow-up. Successful event rates were significantly higher in patients who received ESI than in patients who received conservative treatment. There were no statistically significant differences in functional improvement after ESI and conservative treatment at short-term and intermediate-term follow-up. The limitations of this meta-analysis resulted from the variation in types of interventions and small sample size. CONCLUSIONS According to the results of this meta-analysis, the use of ESI is more effective for alleviating lumbosacral radicular pain than conservative treatments in terms of short-term and intermediate-term. Patients also reported more successful outcomes after receiving ESI when compared to conservative treatment. However, this effect was not maintained at long-term follow-up. This meta-analysis will help guide clinicians in making decisions for the treatment of patients with lumbosacral radicular pain, including the use of ESI, particularly in the management of pain at short-term.

Abstract
While spinal manipulative therapy (SMT) is recommended for the treatment of spinal disorders, concerns exist about adverse events associated with the intervention. Adequate reporting of adverse events in clinical trials would allow for more accurate estimations of incidence statistics through meta-analysis. However, it is not currently known if there are factors influencing adverse events reporting following SMT in randomized clinical trials (RCTs). Thus our objective was to investigate predictive factors for the reporting of adverse events in published RCTs involving SMT. The Physiotherapy Evidence Database (PEDro) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for RCTs involving SMT. Domains of interest included: sample size; publication date relative to the 2010 CONSORT statement; risk of bias; the region treated; and number of intervention sessions. 7398 records were identified, of which 368 articles were eligible for inclusion. A total of 140 (38.0%) articles reported on adverse events. Articles were more likely to report on adverse events if they possessed larger sample sizes, were published after the 2010 CONSORT statement, had a low risk of bias and involved multiple intervention sessions. The region treated was not a significant predictor for reporting on adverse events. Predictors for reporting on adverse events included larger sample size, publication after the 2010 CONSORT statement, low risk of bias and trials involving multiple intervention sessions. We recommend that researchers focus on developing robust methodologies and participant follow-up regimens for RCTs involving SMT.

Abstract
BACKGROUND Low back pain (LBP) is associated with enormous personal and societal burdens, especially when it reaches the chronic stage of the disorder (pain for a duration of more than three months). Indeed, individuals who reach the chronic stage tend to show a more persistent course, and they account for the majority of social and economic costs. As a result, there is increasing emphasis on the importance of intervening at the early stages of LBP.According to the biopsychosocial model, LBP is a condition best understood with reference to an interaction of physical, psychological, and social influences. This has led to the development of multidisciplinary biopsychosocial rehabilitation (MBR) programs that target factors from the different domains, administered by healthcare professionals from different backgrounds.This review is an update of a Cochrane Review on MBR for subacute LBP, which was published in 2003. It is part of a series of reviews on MBR for musculoskeletal pain published by the Cochrane Back and Neck Group and the Cochrane Musculoskeletal Group. OBJECTIVES To examine the effectiveness of MBR for subacute LBP (pain for a duration of six to 12 weeks) among adults, with a focus on pain, back-specific disability, and work status. SEARCH METHODS We searched for relevant trials in any language by a computer-aided search of CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and two trials registers. Our search is current to 13 July 2016. SELECTION CRITERIA We included randomised controlled trials (RCTs) of adults with subacute LBP. We included studies that investigated a MBR program compared to any type of control intervention. We defined MBR as an intervention that included a physical component (e.g. pharmacological, physical therapy) in combination with either a psychological, social, or occupational component (or any combination of these). We also required involvement of healthcare professionals from at least two different clinical backgrounds with appropriate training to deliver the component for which they were responsible. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. In particular, the data extraction and 'risk of bias' assessment were conducted by two people, independently. We used the Cochrane tool to assess risk of bias and the GRADE approach to assess the overall quality of the evidence for each outcome. MAIN RESULTS We included a total of nine RCTs (981 participants) in this review. Five studies were conducted in Europe and four in North America. Sample sizes ranged from 33 to 351. The mean age across trials ranged between 32.0 and 43.7 years.All included studies were judged as having high risk of performance bias and high risk of detection bias due to lack of blinding, and four of the nine studies suffered from at least one additional source of possible bias.In MBR compared to usual care for subacute LBP, individuals receiving MBR had less pain (four studies with 336 participants; SMD -0.46, 95% CI -0.70 to -0.21, moderate-quality of evidence due to risk of bias) and less disability (three studies with 240 participants; SMD -0.44, 95% CI -0.87 to -0.01, low-quality of evidence due to risk of bias and inconsistency), as well as increased likelihood of return-to-work (three studies with 170 participants; OR 3.19, 95% CI 1.46 to 6.98, very low-quality of evidence due to serious risk of bias and imprecision) and fewer sick leave days (two studies with 210 participants; SMD -0.38 95% CI -0.66 to -0.10, low-quality of evidence due to risk of bias and imprecision) at 12-month follow-up. The effect sizes for pain and disability were low in terms of clinical meaningfulness, whereas effects for work-related outcomes were in the moderate range.However, when comparing MBR to other treatments (i.e. brief intervention with features from a light mobilization program and a graded activity program, functional restoration, brief clinical intervention including education and advice on exercise, and psychological counselling), we found no differences between the groups in terms of pain (two studies with 336 participants; SMD -0.14, 95% CI -0.36 to 0.07, low-quality evidence due to imprecision and risk of bias), functional disability (two studies with 345 participants; SMD -0.03, 95% CI -0.24 to 0.18, low-quality evidence due to imprecision and risk of bias), and time away from work (two studies with 158 participants; SMD -0.25 95% CI -0.98 to 0.47, very low-quality evidence due to serious imprecision, inconsistency and risk of bias). Return-to-work was not reported in any of the studies.Although we looked for adverse events in both comparisons, none of the included studies reported this outcome. AUTHORS' CONCLUSIONS On average, people with subacute LBP who receive MBR will do better than if they receive usual care, but it is not clear whether they do better than people who receive some other type of treatment. However, the available research provides mainly low to very low-quality evidence, thus additional high-quality trials are needed before we can describe the value of MBP for clinical practice.

Abstract
Background Although chiropractors in the United States (US) have long suggested that their approach to managing spine pain is less costly than other health care providers (HCPs), it is unclear if available evidence supports this premise. Methods A systematic review was conducted using a comprehensive search strategy to uncover studies that compared health care costs for patients with any type of spine pain who received chiropractic care or care from other HCPs. Only studies conducted in the US and published in English between 1993 and 2015 were included. Health care costs were summarized for studies examining: 1. private health plans, 2. workers’ compensation (WC) plans, and 3. clinical outcomes. The quality of studies in the latter group was evaluated using a Consensus on Health Economic Criteria (CHEC) list. Results The search uncovered 1276 citations and 25 eligible studies, including 12 from private health plans, 6 from WC plans, and 7 that examined clinical outcomes. Chiropractic care was most commonly compared to care from a medical physician, with few details about the care received. Heterogeneity was noted among studies in patient selection, definition of spine pain, scope of costs compared, study duration, and methods to estimate costs. Overall, cost comparison studies from private health plans and WC plans reported that health care costs were lower with chiropractic care. In studies that also examined clinical outcomes, there were few differences in efficacy between groups, and health care costs were higher for those receiving chiropractic care. The effects of adjusting for differences in sociodemographic, clinical, or other factors between study groups were unclear. Conclusions Although cost comparison studies suggest that health care costs were generally lower among patients whose spine pain was managed with chiropractic care, the studies reviewed had many methodological limitations. Better research is needed to determine if these differences in health care costs were attributable to the type of HCP managing their care.

Abstract
OBJECTIVE This project determined the feasibility of conducting larger studies assessing the relationship between cavitation and zygapophyseal (Z) joint gapping following spinal manipulative therapy (SMT). METHODS Five healthy volunteers (average age, 25.4 years) were screened and examined against inclusion and exclusion criteria. High-signal magnetic resonance imaging (MRI) markers were fixed to T12, L3, and S1 spinous processes. Scout images were taken to verify the location of the markers. Axial images of the L4/L5 and L5/S1 levels were obtained in the neutral supine position. Following the first MRI, accelerometers were placed over the same spinous processes; and recordings were made from them during side-posture positioning and SMT. The accelerometers were removed, and each subject was scanned in side-posture. The greatest central anterior to posterior Z joint spaces (gap) were measured from the first and second MRI scans. Values obtained from the first scan were subtracted from those of the second, with a positive result indicating an increase in gapping following SMT (positive gapping difference). Gapping difference was compared between the up-side (SMT) joints vs the down-side (non-SMT) joints and between up-side cavitation vs up-side noncavitation joints. RESULTS Greater gapping was found in Z joints that received SMT (0.5 ± 0.6 mm) vs non-SMT joints (-0.2 ± 0.6 mm), and vertebral segments that cavitated gapped more than those that did not cavitate (0.8 ± 0.7 vs 0.4 ± 0.5 mm). CONCLUSIONS A future clinical study is quite feasible. Forty subjects (30 in an SMT group and 10 in a control group) would be needed for appropriate power (0.90).

Abstract
Background Back-related leg pain (BRLP) is a common variation of low back pain (LBP), with lifetime prevalence estimates as high as 40%. Often disabling, BRLP accounts for greater work loss, recurrences, and higher costs than uncomplicated LBP and more often leads to surgery with a lifetime incidence of 10% for those with severe BRLP, compared to 1-2% for those with LBP. In the US, half of those with back-related conditions seek CAM treatments, the most common of which is chiropractic care. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care. Methods/Design This study is a two-site, prospective, parallel group, observer-blinded randomized clinical trial (RCT). A total of 192 study patients will be recruited from the Twin Cities, MN (n = 122) and Quad Cities area in Iowa and Illinois (n = 70) to the research clinics at WHCCS and PCCR, respectively. It compares two interventions: chiropractic spinal manipulative therapy (SMT) plus home exercise program (HEP) to HEP alone (minimal intervention comparison) for patients with subacute or chronic back-related leg pain. Discussion Back-related leg pain (BRLP) is a costly and often disabling variation of the ubiquitous back pain conditions. As health care costs continue to climb, the search for effective treatments with few side-effects is critical. While SMT is the most commonly sought CAM treatment for LBP sufferers, there is only a small, albeit promising, body of research to support its use for patients with BRLP. This study seeks to fill a critical gap in the LBP literature by performing the first full scale RCT assessing chiropractic SMT for patients with sub-acute or chronic BRLP using important patient-oriented and objective biomechanical outcome measures.

Abstract
In this systematic review, we present a comprehensive and up-to-date systematic review of the literature as it relates to the efficacy and effectiveness of spinal manipulation or mobilization in the management of cervical, thoracic, and lumbar-related extremity pain. There is moderate quality evidence that spinal manipulation is effective for the treatment of acute lumbar radiculopathy. The quality of evidence for chronic lumbar spine-related extremity symptoms and cervical spine-related extremity symptoms of any duration is low or very low. At present, no evidence exists for the treatment of thoracic radiculopathy. Future high-quality studies should address these conditions.

Abstract
BACKGROUND CONTEXT Low back pain (LBP) continues to be a very prevalent, disabling, and costly spinal disorder. Numerous interventions are routinely used for symptoms of acute LBP. One of the most common approaches is spinal manipulation therapy (SMT). PURPOSE To assess the current scientific literature related to SMT for acute LBP. PATIENT SAMPLE Not applicable. OUTCOME MEASURES Not applicable. DESIGN Systematic review (SR). METHODS Literature was identified by searching MEDLINE using indexed and free text terms. Studies were included if they were randomized controlled trials (RCTs) published in English, and SMT was administered to a group of patients with LBP of less than 3 months. RCTs included in two previous SRs were also screened, as were reference lists of included studies. Combined search results were screened for relevance by two reviewers. Data related to methods, risk of bias, harms, and results were abstracted independently by two reviewers. RESULTS The MEDLINE search returned 699 studies, of which six were included; an additional eight studies were identified from two previous SRs. There were 2,027 participants in the 14 included RCTs, which combined SMT with education (n=5), mobilization (MOB) (n=4), exercise (n=3), modalities (n=3), or medication (n=2). The groups that received SMT were most commonly compared with those receiving physical modalities (n=7), education (n=6), medication (n=5), exercise (n=5), MOB (n=3), or sham SMT (n=2). The most common providers of SMT were chiropractors (n=5) and physical therapists (n=5). Most studies (n=6) administered 5 to 10 sessions of SMT over 2 to 4 weeks for acute LBP. Outcomes measured included pain (n=10), function (n=10), health-care utilization (n=6), and global effect (n=5). Studies had a follow-up of less than 1 month (n=7), 3 months (n=1), 6 months (n=3), 1 year (n=2), or 2 years (n=1). When compared with various control groups, results for improvement in pain in the SMT groups were superior in three RCTs and equivalent in three RCTs in the short term, equivalent in four RCTs in the intermediate term, and equivalent in two RCTs in the long term. For improvement in function, results from the SMT groups were superior in one RCT and equivalent in four RCTs in the short term, superior in one RCT and equivalent in one RCT in the intermediate term, and equivalent in one RCT and inferior in one RCT in the long term. No harms related to SMT were reported in these RCTs. CONCLUSIONS Several RCTs have been conducted to assess the efficacy of SMT for acute LBP using various methods. Results from most studies suggest that 5 to 10 sessions of SMT administered over 2 to 4 weeks achieve equivalent or superior improvement in pain and function when compared with other commonly used interventions, such as physical modalities, medication, education, or exercise, for short, intermediate, and long-term follow-up. Spine care clinicians should discuss the role of SMT as a treatment option for patients with acute LBP who do not find adequate symptomatic relief with self-care and education alone.

Abstract
BACKGROUND Low back pain (LBP) is a prevalent and costly condition in the United States. Evidence suggests there is no one treatment which is best for all patients, but instead several viable treatment options. Additionally, multidisciplinary management of LBP may be more effective than monodisciplinary care. An integrative model that includes both complementary and alternative medicine (CAM) and conventional therapies, while also incorporating patient choice, has yet to be tested for chronic LBP.The primary aim of this study is to determine the relative clinical effectiveness of 1) monodisciplinary chiropractic care and 2) multidisciplinary integrative care in 200 adults with non-acute LBP, in both the short-term (after 12 weeks) and long-term (after 52 weeks). The primary outcome measure is patient-rated back pain. Secondary aims compare the treatment approaches in terms of frequency of symptoms, low back disability, fear avoidance, self-efficacy, general health status, improvement, satisfaction, work loss, medication use, lumbar dynamic motion, and torso muscle endurance. Patients' and providers' perceptions of treatment will be described using qualitative methods, and cost-effectiveness and cost utility will be assessed. METHODS AND DESIGN This paper describes the design of a randomized clinical trial (RCT), with cost-effectiveness and qualitative studies conducted alongside the RCT. Two hundred participants ages 18 and older are being recruited and randomized to one of two 12-week treatment interventions. Patient-rated outcome measures are collected via self-report questionnaires at baseline, and at 4, 12, 26, and 52 weeks post-randomization. Objective outcome measures are assessed at baseline and 12 weeks by examiners blinded to treatment assignment. Health care cost data is collected by self-report questionnaires and treatment records during the intervention phase and by monthly phone interviews thereafter. Qualitative interviews, using a semi-structured format, are conducted with patients at the end of the 12-week treatment period and also with providers at the end of the trial. DISCUSSION This mixed-methods randomized clinical trial assesses clinical effectiveness, cost-effectiveness, and patients' and providers' perceptions of care, in treating non-acute LBP through evidence-based individualized care delivered by monodisciplinary or multidisciplinary care teams.

Abstract
BACKGROUND Low back pain (LBP) and neck pain (NP) are common conditions in old age, leading to impaired functional ability and decreased independence. Manual and exercise therapies are common and effective therapies for the general LBP and NP populations. However, these treatments have not been adequately researched in older LBP and NP sufferers. The primary aim of these studies is to assess the relative clinical effectiveness of 1) manual treatment plus home exercise, 2) supervised rehabilitative exercise plus home exercise, and 3) home exercise alone, in terms of patient-rated pain, for senior LBP and NP patients. Secondary aims are to compare the three treatment approaches in regards to patient-rated disability, general health status, satisfaction, improvement and medication use, as well as objective outcomes of spinal motion, trunk strength and endurance, and functional ability. Cost-effectiveness and cost-utility will also be assessed. Finally, using qualitative methods, older LBP and NP patient's perceptions of treatment will be explored and described. METHODS/DESIGN This paper describes the design of two multi-methods clinical studies focusing on elderly patients with non-acute LBP and NP. Each study includes a randomized clinical trial (RCT), a cost-effectiveness study alongside the RCT, and a qualitative study. Four hundred and eighty participants (240 per study), ages 65 and older, will be recruited and randomized to one of three, 12-week treatment programs. Patient-rated outcome measures are collected via self-report questionnaires at baseline and at 4, 12, 26, and 52 weeks post-randomization. Objective outcomes are assessed by examiners masked to treatment assignment at baseline and 12 weeks. Health care cost data is collected through standardized clinician forms, monthly phone interviews, and self-report questionnaires throughout the study. Qualitative interviews using a semi-structured format are conducted at the end of the 12 week treatment period. DISCUSSION To our knowledge, these are the first randomized clinical trials to comprehensively address clinical effectiveness, cost-effectiveness, and patients' perceptions of commonly used treatments for elderly LBP and NP sufferers.

Abstract
Spinal manipulations have been shown to be efficient for common low back pain; they remain an option in the treatment of symptomatic lumbar disk herniation. From data in the literature, the author discusses the interest of spinal manipulations with a "thrust" at the level of disk herniation and concludes that this therapy, performed by an experienced physician and under conditions of strict application, could be an option in the treatment of subacute and chronique disc herniation.

Abstract
OBJECTIVE To assess the feasibility of recruiting sciatica patients and to evaluate their compliance in preparation for a full-scale randomized clinical trial. We also aimed to determine the responsiveness of key outcome measures. METHODS Thirty-two subjects were randomly assigned to spinal manipulation (n=11), epidural steroid injections (n=11), or self-care education (n=10). No between-group comparisons were planned because of the small sample size. RESULTS At week 12 (the end of the treatment phase), the outcome measures indicating the most improvement/change were the Oswestry disability score (mean, 22.9; SD, 19.9; effect size [ES], 1.8), leg pain severity (mean, 2.9; SD, 1.7; ES, 1.7), and if the symptoms were bothersome (mean, 25.2; SD, 16.0; ES, 1.6). Twenty-four patients were either "very satisfied" or "completely satisfied," and 22 of 32 patients reported 75% or 100% improvement. After 52 weeks, the outcome measure showing the most improvement/change was leg pain severity (mean, 2.3; SD, 2.6; ES, 1.35), followed by the Oswestry disability score (mean, 15.6; SD, 20; ES, 1.2) and if symptoms were bothersome (mean, 18.1; SD, 22.6; ES, 1.1). Eighteen patients were either "very satisfied" or "completely satisfied," and 15 of 32 patients reported 75% or 100% improvement. CONCLUSIONS The results of this pilot study suggest that it is feasible to recruit subacute and chronic sciatica patients and to obtain their compliance for a full-scale randomized clinical.

Abstract
OBJECTIVE To acquire information for designing a large clinical trial and determining its feasibility and to make preliminary estimates of the relationship between headache outcomes and the number of visits to a chiropractor. DESIGN Randomized, controlled trial. SETTING Private practice in a college outpatient clinic and in the community. SUBJECTS Twenty-four adults with chronic cervicogenic headache. METHODS Patients were randomly allocated to 1, 3, or 4 visits per week for 3 weeks. All patients received high-velocity low-amplitude spinal manipulation. Doctor of Chiropractics could apply up to 2 physical modalities at each visit from among heat and soft tissue therapy. They could also recommend modification of daily activities and rehabilitative exercises. Outcomes included 100-point Modified Von Korff pain and disability scales, and headaches in last 4 weeks. RESULTS Only 1 participant was insufficiently compliant with treatment (3 of 12 visits), and 1 patient was lost to follow-up. There was substantial benefit in pain relief for 9 and 12 treatments compared with 3 visits. At 4 weeks, the advantage was 13.8 ( P = .135) for 3 visits per week and 18.7 (P = .041) for 4 visits per week. At the 12-week follow-up, the advantage was 19.4 (P = .035) for 3 visits per week and 18.1 (P = .048) for 4 visits per week. CONCLUSION A large clinical trial on the relationship between pain relief and the number of chiropractic treatments is feasible. Findings give preliminary support for the benefit of larger doses, 9 to 12 treatments, of chiropractic care for the treatment of cervicogenic headache.

Abstract
BACKGROUND Multidisciplinary biopsychosocial rehabilitation programs are widely applied for chronic low back pain patients. The biopsychosocial approach can also prevent chronicity, by providing rehabilitation for patients who still have pain past the initial acute phase. Nevertheless, multidisciplinary treatment programmes are often laborious and long processes and require good collaboration between the patient, the rehabilitation team and the work place. By using workplace visits and developing close relationships with occupational health care providers, one might expect patients' working ability to improve. OBJECTIVES The objective of this systematic review was to determine the effectiveness of multidisciplinary rehabilitation for subacute low back pain among working age adults. SEARCH STRATEGY The reviewed studies for this review were electronically identified from MEDLINE, EMBASE, PsycLIT, CENTRAL, Medic, the Science Citation Index, reference checking and consulting experts in the rehabilitation field. The original search was planned and performed for the broader area of musculoskeletal disorders. Trials on subacute low back pain were separated afterwards. The literature search was last updated in November 2002 in EMBASE and MEDLINE. SELECTION CRITERIA From all references identified in our original search, we selected randomised controlled trials (RCTs) and non-randomised controlled clinical trials (CCTs). Trials had to assess the effectiveness of multidisciplinary rehabilitation for working age patients suffering from subacute low back pain (more than four weeks but less than three months). The rehabilitation program was required to be multidisciplinary, i.e., it had to consist of a physician's consultation plus either a psychological, social or vocational intervention, or a combination of these. DATA COLLECTION AND ANALYSIS Four reviewers blinded to journal and author selected trials that met the specified inclusion criteria. Two experts in the field of rehabilitation evaluated the clinical relevance and applicability of the findings of the selected studies for actual clinical use. Two other reviewers blinded to journal and author extracted the data and assessed the main results and the methodological quality of the studies, using standardized forms. Finally, a qualitative analysis was performed to evaluate the level of scientific evidence for the effectiveness of multidisciplinary rehabilitation. MAIN RESULTS After screening 1808 abstracts, and the references of 65 reviews, we found only two relevant studies that satisfied our criteria on subacute low back pain. No more studies were found during the updates. Both studies were considered to be methodologically low quality RCTs. The clinical relevance of included studies was sufficient. There was moderate scientific evidence showing that multidisciplinary rehabilitation, which includes a workplace visit or more comprehensive occupational health care intervention, helps patients to return to work faster, results in fewer sick leaves and alleviates subjective disability. REVIEWER'S CONCLUSIONS We conclude that there is moderate evidence of positive effectiveness of multidisciplinary rehabilitation for subacute low back pain and that a workplace visit increases the effectiveness. But because this evidence is based on trials that had some methodological shortcomings, and several expensive multidisciplinary rehabilitation programmes are commonly used for uncomplicated/non-specific subacute low back problems, there is an obvious need for high quality trials in this field.
