Low back pain (LBP) is a well-recognized public health problem with no clear gold standard medical approach to treatment. Thus, those with LBP frequently turn to treatments such as spinal manipulation (SM). Many clinical trials have been conducted to evaluate the efficacy or effectiveness of SM for LBP.
The primary objective of this paper was to describe the current literature on patient-centered outcomes following a specific type of commonly used SM, high-velocity low-amplitude (HVLA), in patients with LBP. A systematic search strategy was used to capture all LBP clinical trials of HVLA using our predefined patient-centered outcomes: visual analogue scale, numerical pain rating scale, Roland-Morris Disability Questionnaire, and the Oswestry Low Back Pain Disability Index.
Of the 1,294 articles identified by our search, 38 met our eligibility criteria. Like previous SM for LBP systematic reviews, this review shows a small but consistent treatment effect at least as large as that seen in other conservative methods of care.
The heterogeneity and inconsistency in reporting within the studies reviewed makes it difficult to draw definitive conclusions. Future SM studies for LBP would benefit if some of these issues were addressed by the scientific community before further research in this area is conducted.
Palmer Research Summary Series
In this study, authors systematically searched the scientific literature (1974-2011) reporting randomized clinical trials including high velocity, low amplitude (HVLA) spinal manipulation (SM) for low back pain (LBP).
Patient-centered outcomes measured were the:
Visual Analogue Scale (VAS)
Numerical Rating Scale (NRS)
Roland-Morris Disability Questionnaire (RM), and the
Oswestry Low Back Pain Disability Index (OSW).
Study results included:
Of 1294 articles identified in the initial publication search, 38 met the criteria for the study
The 2 most common pain rating scales were - NRS and VAS
The 2 most common patient-reported measures of low back function were - RM and OSW
Small but consistent pain reduction and functional improvement followed HVLA-SM treatment
Heterogeneity in study methods and inconsistency in reporting/recording pain limited more
HVLA SM provides a small and consistent pain reducing and functional improvement effect, greater than or equal to other conservative treatments available for patients with LBP.
Doctors and patients can be confident in recommending or choosing to receive HVLA-SM for LBP. The body of research supporting its effectiveness relative to other available treatments
suggests patients have the choice of several treatment options. Future research would benefit from consistent study designs and pain measurement/reporting. Reporting clear details of the frequency and timing of treatments used in clinical trials would also be useful.

From the FULL TEXT Article:
Low back pain (LBP) is a well-recognized public health problem with lifetime prevalence ranging from 11% to 84% and median cost per quality-adjusted life year of $13,015 (Dagenais et al., 2008; Walker, 2000). Point prevalence within the last 3 months is estimated at 17% (Deyo et al., 2006). At the most recent meeting of the Tenth International Forum for Primary Care Research on Low Back Pain participants concluded that ‘‘the LBP epidemic remains a burden in Western countries’’ (Pransky et al., 2011).
There is no single standard approach to medical care for LBP.
Carey et al. recently conducted a survey examining health care utilization patterns in patients with chronic LBP (Carey et al., 2009). They found high health care utilization in this group, with an average of 21 visits to 2.7 provider-types annually. Many of the tests and treatments used did not conform to evidence-based practice.
The authors concluded that
(1) care utilization for chronic LBP is very high, including high use rates for advanced imaging, narcotics, and physical treatments;
(2) use of evidence-based treatments are low when compared with current best evidence; and
(3) many treatments are over-utilized. A recent review of clinical practice guidelines for the treatment of LBP found that acute LBP management recommendations included three interventions: patient education, acetaminophen or nonsteroidal anti-inflammatory and spinal manipulation (Dagenais et al., 2010).
Spinal manipulation (SM) is commonly used to treat low back pain (LBP). SM is the therapeutic application of a load (force) to specific body tissues (usually vertebral joints). Load delivery varies with respect to velocity, amplitude, frequency, choice of lever, and direction of force application (Herzog, 2000; Triano, 2000).
Because little is understood about the pathophysiology of most
LBP, and the exact mechanism(s) of action of SM’s effect on LBP is largely unknown, clinical trials have primarily depended upon patient-perceived outcomes such as pain level and functional health status (Bronfort et al., 2008; Lawrence et al., 2008). These have traditionally been considered ‘‘soft’’ outcomes by the scientific community. However, the recent creation of the Patient-Centered Outcomes Research Institute (PCORI) in Washington, DC within the 2010 Patient Protection and Affordable Care Act by the US Congress has brought more focus and a growing acceptance of patientperceived or ‘‘patient-centered’’ outcomes, at least in the context of comparative effectiveness research. While this has been a recent phenomenon, a patient-centered perspective has always been the primary focus of SM research because of a lack of other available outcomes.
A recent article found that the most commonly used patient-based outcome assessments in chiropractic SM research were a mix of both pain and functional health status measures, including
the Visual Analogue Scale (VAS),
the Numerical Rating Scale (NRS),
the Roland Morris Disability Questionnaire (RM),
the Oswestry Low Back Pain Disability Index (OSW) and
the Short Form-36 (SF-36) (Khorsan et al., 2008).
Numerous systematic reviews evaluating the effects of various
SM techniques for low back pain have been conducted over the
past 10 years (Assendelft et al., 2003; Bronfort et al., 2010; Ferreira et al., 2003; Furlan et al., 2010; Koes et al., 2010; Pengel et al., 2002; Rubinstein et al., 2011; van Tulder et al., 2005; van Tulder, 2006; Walker et al., 2010). The majority have found that SM conveys a modest but consistent benefit for patients with LBP at least as large as commonly used alternative treatments. This is despite marked heterogeneity in study design and quality.
Our review is unique in that only studies comparing high-velocity, low-amplitude (HVLA) SM are included - because HVLA SM is commonly used both in clinical trials and in the clinical setting (Christensen et al., 2010). We also present these data in a way that allows us to separately consider the data from specific patient-centered outcome instruments. In this paper we present tables showing the two most commonly used pain rating scales (NRS and VAS) and the two most commonly used patient-reported measures of low back function (RM and OSW) in order to discern both similarities and differences in use and meaning. Included studies were restricted to those whose primary or secondary outcome was VAS, NRS, RM, and/or OSW. This allowed us to concentrate on studies that had similar outcome measures, decreasing heterogeneity while still including the most recent studies available. The primary objective of this paper was to describe the current literature on patient-centered outcomes in randomized controlled trials of HVLA SM in patients with low back pain.
Sources of information
The relevant studies were identified using the following databases: PubMED (an index to Medline), the Cochrane Library, and Index to Chiropractic Literature (ICL). All databases were searched from inception through April 2011.
Search terms and delimiters
Search terms for all databases (except ICL) were
‘‘low back pain’’ OR ‘‘back’’ OR ‘‘back pain’’ OR ‘‘back injuries’’ OR ‘‘sciatica’’ OR ‘‘LBP’’ AND ‘‘manip’’ OR ‘‘mobili’’ OR ‘‘manual therap.’’
The ICL database was searched using
‘‘low back pain’’ OR ‘‘back’’ OR ‘‘back pain’’ OR ‘‘back injuries’’ OR ‘‘sciatica’’ OR ‘‘LBP.’’
All searches were limited to those studies written in English and involving human
As shown in Fig. 1, a systematic search strategy was used to capture all LBP clinical trials of SM using our predefined patientcentered outcomes. First, the sources of information were searched using the search terms and delimiters. We then cross referenced our findings with MESH headings and hand-checked reference lists of relevant studies to identify cited articles not captured by electronic searches. Two independent reviewers screened all of the potential relevant studies for selection criteria. Discrepancies were settled by a third independent reviewer (KAP). Second, abstracts were screened for absolute exclusionary criteria by an independent reviewer with any discrepancies resolved by at least three other reviewers. The final step was a full-text review for selection criteria conducted as a group by at least four of the authors.
Literature retrieval process flow chart.
Articles were included if they met the following criteria:
1 - English language;
2 - non-specific low back pain as identified by the author;
3 - involved adult human subjects, 18 years of age or older;
4 - included HVLA as a category of spinal manipulative therapy;
however, studies of SM under anesthesia were excluded;
5 - a randomized clinical trial that included a separate and distinct control or comparative treatment group;
6 - articles that used intention-to-treat analysis and had extractable data;
7 - use of one or more of the following patient-centered outcomes: VAS, NRS, RM, and OSW.
SF-36 data were not included in this review because the majority of studies reviewed provided SF-36 data only when describing baseline characteristics. Studies including other forms of SM (e.g. mobilization techniques) that did not have an HVLA arm were not included. Mechanistic and basic science trials conducted on human participants were excluded as were studies where the only comparative group was another SM method.
For purposes of this review, SM was defined as a manually
delivered high-velocity low-amplitude force or thrust applied to
a vertebral or pelvic joint with the intent of creating a momentary separation of joint surfaces and cavitation. Components of SM, such as velocity and amplitude, have variable ranges of implementation. Most definitions of SM refer to a thrust or an increasing magnitude of force that peaks over a finite period of time (Evans, 2010; Evans and Lucas, 2010). Cavitation alone is not considered a necessary component, though it is often considered one of the goals of this procedure. Manual contacts over the intended vertebral or pelvic joint (short lever) or over distant sites (long lever) were considered under our definition of spinal manipulation.
For this review, patient-centered outcomes have been given the
operational definition: patient self-report questionnaires related to pain and physical/emotional/social functioning.
Currently few methods exist to reliably confirm a specific diagnosis for the cluster of symptoms categorized as non-specific or idiopathic LBP. However, identifying specific patient characteristics of LBP can demarcate similarities and differences between study populations. We found that symptom duration varied widely among the included study population and therefore added a classification to each study based upon guideline definitions by the 2007 American College of Physicians and American Pain Society: acute pain (0-4 wks), subacute pain (4-12 wks), and chronic pain (12 or more wks) (Chou et al., 2007). Study populations were further classified according to the Quebec Task Force (QTF) classification system (Fig. 2) (Spitzer et al., 1995).
Quebec task force (QTF) classification system
The timing of the primary endpoint for each study is presented
in the tables. For those studies reporting outcomes at durations beyond the primary endpoint, we included the longest term followup available, up to 1 year.
For each article we extracted means, standard deviations (SD)
and confidence intervals (CI) from the tables and text, but not from figures. We converted VAS scores reported in cm to mm and OSW scores reported on a 50-point scale to a 100-point scale. For articles where median and interquartile ranges were reported, we assumed the median was equivalent to the mean and the interquartile range was equivalent to 1.35 times the standard deviation (Higgins and Green, 2009).
Within each group, we extracted mean changes between
baseline and follow-up with confidence intervals directly from
the article when possible. When only the means for baseline and
follow-up were given, we calculated the difference between means
recognizing that the actual mean change could differ due to missing data. When the SD of a change was given, we used it to estimate the standard error (SE) and calculate a 95% CI. When the SD of the change variable was not reported, but the SD of both the baseline and follow-up variables were, we conservatively assumed there was no correlation between baseline and follow-up measures to estimate the SD of the change variable. We then used this SD to estimate the SE and calculate a 95% CI.
Between-groups, we extracted mean differences and CIs directly
from the article when possible. Some articles reported differences in mean changes and some reported differences in follow-up means adjusted for the baseline outcome variable. Some articles adjusted for covariates and others did not. We have not distinguished between these different methods. When between-group differences were not reported, we calculated them by using the reported group means. If group means were not given, we used the within-group means calculated as described above. When between-group CIs were not reported, we calculated a pooled estimate of the SDs using the reported within-group SDs or those
estimated as described above when within-group SDs were not reported. The pooled estimate of the SDs was then used to estimate the standard error of the differences between means to calculate a 95% CI.
Risk of bias
Independent quality rating went beyond the scope of this study.
However, we reviewed and combined quality ratings from 2 Cochrane and 1 Agency for Healthcare Research and Quality reviews (Furlan et al., 2010; Rubinstein et al., 2011; Walker et al., 2010) for the studies included in this review.
Of the 1,294 articles identified by our initial search, 38 articles met the selection criteria (Fig. 1).
The first three tables show studies that were:
(1) excluded based on abstract (Table 1); (Page 673)
(2) excluded based on full article assessment (Table 2) (Page 674); and
. (Page 676)
(Tables 47) give with-in group mean changes and between-group mean differences with 95% CIs of the VAS, NRS, RM and OSW, respectively, for the studies included in this review. Below is a description of each patient-centered outcome measure with a brief summary of our findings.
The visual analogue scale is a 100-mm line. The ends of the
line are anchored with response categories, which are generally
‘‘no pain’’ at the 0 mm end of the line and a descriptor such
as ‘‘unbearable pain’’ or ‘‘worst pain possible’’ at the 100 mm
end of the line. The minimum clinically important difference
(MCID) is defined as the smallest difference in the outcome perceived by patients as beneficial (Jaeschke et al., 1989). The MCID for VAS has been reported to range from 20 to 35 mm, with the smaller difference typically for subacute and chronic LBP patients and the larger difference for acute LBP patients (Hagg
et al., 2003; Ostelo and de Vet, 2005; Vela et al., 2011). Mean
change scores were similar at both short and long term followups
The numerical pain rating scale asks participants to rate their
level of pain on an ordinal 11 point scale, anchored with response categories in which 0 represents ‘‘no pain’’ and 10 represents ‘‘unbearable pain’’ or ‘‘worst pain possible’’ (Table 5). The MCID is considered to be a change of 2.5 points (van der Roer et al., 2006). Between-group treatment effects tended to favor SM, but the differences were not clinically or statistically significant.
The modified Roland-Morris Disability Questionnaire assesses
LBP-related disability and has a MCID estimated at 2-3.5 points
(Bombardier et al., 2001; Ostelo and de Vet, 2005). The RM is a
1-page questionnaire and has shown both good reliability and
validity (Roland and Fairbank, 2000) and is sensitive to clinical change in patients with LBP (Deyo et al., 1990; Riddle et al., 1998; Stratford et al., 2000). Within-group changes were higher in studies focused on acute LBP when compared to chronic LBP (Table 5). Between-group differences were inconsistent. With rare exceptions, long-term outcomes were similar to short-term outcomes.
The Oswestry Low Back Pain Disability Index consists of 10
questions assessing pain intensity and limitations in various activities (Fairbank et al., 1980). Scores range from 0 to 50 points and are transformed into a percentage score, or score out of 100 points. The MCID is 6%, with recent discussion suggesting that the MCID should be 10% (Ostelo et al., 2008; Vela et al., 2011). Long-term outcomes, when available, were similar to short-term outcomes (Table 6).
We were interested in summarizing effect sizes in SM and SM+
(other therapies such as physical therapy, medical care, exercise). To accomplish this goal we averaged across mean change scores within-groups and differences of mean change scores betweengroups (Table 8). A wide range of mean change scores were found both within and between-groups across all measures. Withingroup SM + scores were slightly higher. However, this was not true between-groups. The vast majority of comparison groups were active. There are too few sham control groups to draw any conclusions regarding effect sizes of active versus sham study designs.
In Table 9 we present quality ratings for the 20 articles included in this review that were evaluated for quality in one or more of 3 other reviews (Furlan et al., 2010; Rubinstein et al., 2011; Walker et al., 2010). Overall, ratings for the majority of papers showed important gaps in quality markers for RCT study design, especially related to risk of bias, influence of co-intervention, and compliance with interventions.
Although this review specifically focused on studies with HVLA
SM as the primary treatment of interest, our findings are consistent with those found in the latest reviews of SM for LBP that incorporate the most recently published trials (Assendelft et al., 2003; Bronfort et al., 2010; Ferreira et al., 2003; Furlan et al., 2010; Koes et al., 2010; Pengel et al., 2002; Rubinstein et al., 2011; van Tulder et al., 2005; van Tulder, 2006; Walker et al., 2010). We agree with previous conclusions that, although the data are generally insufficient to make strong recommendations, SM appears to be one of several effective treatment options for both acute and chronic
LBP (Assendelft et al., 2003; Bronfort et al., 2004a; Koes et al., 1996; van Tulder et al., 1997; van Tulder, 2006).
We also share concerns over the highly variable quality of extant trials, small effect sizes and large variation in outcomes (Assendelft et al., 2003; Bronfort et al., 2004b; Rubinstein et al., 2011) and agree that the variation is most likely due to a combination of deficient trial methodology, inadequate execution and reporting, the large and non-quantified variation in the SM, and the unknown heterogeneity of LBP patients (Furlan et al., 2010; Hurwitz, 2011; Rubinstein et al., 2011).
The majority of studies included both pain and function as primary and/or secondary outcomes. For pain, either the VAS or NRS was used, while function was measured using either the RM or the OSW. VAS was more widely used than NRS (20 used VAS vs. 8 used NRS), while use of RM and OSW were about equally divided (20 RM vs. 16 OSW). Two studies used both RM and OSW. In the majority of studies, authors did not present a rationale for why one particular pain or function measure was chosen over others. RM was more often used when the provider type was either a DO or a DC, while those studies with a PT provider used either RM or OSW.
While formal assessment of article quality was not specifically
included as part of this review effort, we did observe several issues related to quality that potentially impact our ability to derive useful conclusions from this and similar systematic reviews. For instance, we believe that the wide ranges found in pain change scores between studies are more likely to represent differences in how the data were collected rather than real differences in treatment effect. Specifics regarding VAS anchors were provided in only slightly more than half the studies and, when presented, descriptors varied widely, from ‘‘no pain’’ to ‘‘worst pain,’’ ‘‘pain as bad as it could be,’’ ‘‘max pain,’’ ‘‘worst pain you have ever felt,’’ ‘‘unbearable pain’’ or ‘‘worst imaginable pain/symptoms.’’ The time frame within which participants were asked to rate their pain also varied widely, ranging from ‘‘current’’ to ‘‘within the past 14 days.’’
It is equally difficult to evaluate NRS scores due to lack of consistency in both anchor descriptors and time frame in which the participant was asked to assess his or her pain. Time frames ranged from ‘‘current pain’’ to ‘‘pain over the past 2 weeks,’’ while anchors ranged from ‘‘no pain’’ to either ‘‘worst pain possible’’ or ‘‘worst pain imaginable.’’ In 5 out of 8 studies that used the NRS as a primary or secondary outcome, the anchor descriptors were not specified.
Substantial variability in how pain was recorded and reported,
in combination with the lack of a gold standard function measure, made it difficult to adequately summarize outcomes of clinical trials of HVLA SM for LBP. For this reason we chose not to conduct a meta-analysis or formally synthesize the results. ‘‘Industry standards’’ for measuring both pain and physical functioning in patients with low back pain would make comparisons between SM studies more relevant. It has recently been suggested that assessing the functional capacity of patients may be of greater clinical value than assessing reported pain levels (Pransky et al., 2011). Also, the National Institutes of Health-funded PROMIS initiative has fostered the creation of new measures of both pain and physical functioning that may be useful in the study of LBP (Gershon et al., 2010). These are issues that warrant further discussion among SM investigators.
In our review of these papers, we became aware of other opportunities for standardization. Adherence to the recently updated CONSORT standards (Moher et al., 2010) by SM investigators would help with this effort.
Specifically, we recommend
(1) providing clear descriptions of intervention groups, including SM, in sufficient detail to allow for replication and
(2) describing eligibility criteria in detail.
Adoption of standard classifications to better describe
the nature of LBP studied in a particular trial would also be
useful. While diagnostic code classifications such as ICD-9 or ICD-10 are theoretically more specific, current differences in diagnostic approaches between provider types limit their usefulness in research studies. However, describing LBP according to the Quebec Task Force classifications would be an improvement over current reporting efforts. Also, while the majority of studies we reviewed reported on whether participants had acute, sub-acute or chronic LBP, definitions for these terms were not consistent.
Future studies of SM for LBP would also benefit from the adoption of reporting standards regarding SM intervention delivery. In this review, it was difficult to find consistent information regarding the frequency and/or timing of SM and other treatment visits, or the number of procedures delivered at each visit. Given the complexity of and skill level required for the delivery of SM techniques such as HVLA (Triano et al., 2004), articles would also benefit from inclusion of both the credentials of the clinicians delivering SM or related procedures and their level of expertise (e.g. years in clinical practice, experience with the SM procedure under evaluation).
We found that HVLA SM for LBP appears to convey a small but
consistent treatment effect at least as large as that seen in other conservative methods of care. This finding is similar to that in other systematic reviews of SM of LBP. The heterogeneity and inconsistency in reporting within the studies reviewed makes it difficult to draw definitive conclusions or adequately summarize patient-centered outcomes for clinical trials of HVLA SM for LBP. These are issues that should be addressed by the scientific community before future SM studies for LBP are conducted.
