Summary Objective: To update evidence-based clinical practice guidelines (EBCPG) onmassage therapy compared to control or other treatment for adults (>18 years) suffering fromacute, sub-acute and chronic low back pain (LBP).Methods: A literature search was performed for relevant articles between January 1, 1948 andDecember 31, 2010. Eligibility criteria were then applied focussing on participants, interven-tions, controls, and outcomes, as well as methodological quality. Recommendations basedon this evidence were then assigned a grade (A, B, C, Cþ, D, Dþ, D�) based on their strength.Results: A total of 100 recommendations were formulated from 11 eligible articles, including37 positive recommendations (25 grade A and 12 grade Cþ) and 63 neutral recommendations(49 grade C, 12 grade D, and 2 grade Dþ).Discussion: These guidelines indicate that massage therapy is effective at providing pain reliefand improving functional status.Conclusion: The Ottawa Panel was able to demonstrate that massage interventions are effec-tive to provide short term improvement of sub-acute and chronic LBP symptoms anddecreasing disability at immediate post treatment and short term relief when massage therapyis combined with therapeutic exercise and education.ª 2012 Published by Elsevier Ltd.

Introduction

Low back pain (LBP) is a common condition among theNorth American population, as nearly 80% will experience itat some point in their lives (Frymoyer, 1988). Pain can beacute, lasting from a few days to a few weeks, or maypersist and become chronic if it lasts for more than threemonths (Wilk, 2004; The Philadelphia Panel, 2001). Symp-toms of LBP may include a sharp, stabbing sensation in thelumbosacral region, limited flexibility, range of motion andan inability to stand completely upright without pain(Borkan et al., 1995).

Massage therapy is defined as soft tissue and jointmanipulation using the hands or a handheld device (Imm2010) (Massage Therapy Act, 1991, c. 27, s. 3). An exami-nation of systematic reviews (SRs) and clinical practiceguidelines (CPGs), published within the last five yearssuggests promising outcomes for massage therapy in rela-tion to LBP (Middelkoop et al., 2011; Furlan et al., 2009,2008; Graham et al., 2008; Hettinga et al., 2008; Chou and

Huffman, 2007; Chou et al., 2007; Louw et al., 2007;Luijsterburg et al., 2007; The Philadelphia Panel, 2001).Articles summarizing CPGs for LBP have stated thatmassage therapy is generally recommended, but thatavailable studies are of moderate or weak methodologicalquality, often due to randomization and blinding(Bouwmeester et al., 2009; Dagenais et al., 2010; Pillastriniet al., 2011). Previous SRs and CPGs related to massagetherapy for LBP did not always impose requirements formethodological quality in the studies considered, and didnot indicate if a quantitative methodology was employed toformulate recommendations.

CPGs based on SRs are considered to be solid sources ofevidence to help clinical decision making (Jonas, 2001). Thegoal of this study was to develop recommendations basedon the most recent scientific literature that incorporatesthe graded strength of evidence, and utilizes expert opinionto assess the clinical applicability of the selected trials. It isour aim to give family physicians, physiotherapists, occu-pational therapists, massage therapists, and other

clinicians the latest knowledge regarding the most appro-priate use of massage therapy.

Methodology

Protocols and registration

The development process of the evidence-based clinicalpractice guidelines (EBCPGs) was similar to that of thePhiladelphia Panel (The Philadelphia Panel, 2001) and otherEBCPGs created by the Ottawa Panel (The Ottawa Panel,2005, 2006, 2008). The methodology of this project fol-lowed the Ottawa Expert Panel methods and used a quan-titative approach consistent with the CochraneCollaboration (www.cochrane.org) and the Ottawa Panelevidence grading system (The Ottawa Panel, 2011).

Ottawa Panel experts

The Ottawa Methods Group (OMG), consisting of a panel ofnine methodologists, sought out professional Canadianassociations whose members treat patients with LBP. Apanel of nine specialists with clinical experience in:biostatistics, massage therapy, occupational therapy, andphysiotherapy were then chosen. The OMG and selectedexperts then created the Ottawa Panel, which wasresponsible for the EBCPGs in this report. The OMG alsoassembled a research team with expertise in meta-analysis,research methods, and the development and evaluation ofEBCPGs. Clinical experts were also included as Panelmembers such as massage therapists, physiotherapists,chiropractor, physiatrists and physicians.

Quantitative grading system

In conjunction with the methodology of previous OttawaPanel publications (The Ottawa Panel, 2005, 2006, 2008,2011), the construction of EBCPGs was developed usingthe Appraisal of Guidelines Research and Evaluation

(AGREE) criteria (http://www.agreetrust.org). Therecommendations from the Ottawa Panel are first gradedLevel I if they represent evidence from at least onerandomized controlled trial (RCT) or level II if based onevidence from non-randomized studies. The strength ofthe evidence of the recommendations is then graded as:A, B, Cþ, C, D, Dþ, or D�, corresponding to each level ofthe Ottawa Panel grading system, which considers clinicalimportance, statistical significance and study design (seeTable 1).

Type of participants (P)

To be considered, studies had to include participants overthe age of 18 years, with acute (less than 4 weeks), sub-acute (4e12 weeks) or chronic (longer than 12 weeks) (ThePhiladelphia Panel, 2001) LBP categorized as: mechanicallower back disorders and/or lower back disorders withradicular findings.

Type of interventions (I)

Interventions considered included specific massage therapytechniques (Swedish, fascial or connective tissue releasetechniques, cross fibre friction, and myofascial triggerpoint techniques), either alone or combined with manipu-lation, mobilization, other manual therapy interventions,or other concurrent interventions (ice, heat, TENS, ultra-sound, and combinations thereof).

Type of comparisons (C)

Studies had to compare massage to a control group thatreceived no intervention, placebo (sham laser treatment),usual care, self-care education, relaxation therapy, shammanual therapy or exercise. Studies with head to headcomparisons of different clinical protocols were includedonly if they were comparing two different types of massage(see Table 3).

Type of outcomes (O)

Outcomes of primary interests in the primary studies includeddisability (Roland Morris Disability Questionnaire (RMDQ)),functional status (Oswestry Disability Index (ODI), Quebecback pain disability scale, physical function (SF-36)), pres-ence of pain (short-form McGill questionnaire, system both-ersomeness score, visual analogue scale (VAS), Pain PressureIndex, Pain Rating Index, bodily pain (SF-36), and quality oflife (SF-36)). Trials were excluded if the means and standarddeviations for their primary outcomes were not reported.

Type of study designs

Comparative controlled studies (CCSs) such as randomizedcontrolled trials (RCTs), controlledclinical trials (CCTs), cohortstudies, and case-control studies were eligible for inclusion.Studies were excluded if they did not compare the interven-tions of interest to a control group (e.g. uncontrolled cohorttrials), if the study design was a case-series or a case report, ifthere were more than 20% of withdrawals by participants, orhad a sample size of less than 5 subjects per group.

Information sources

The library scientist (JME) performed a systematic search ofEnglish and French literature using a search strategyproposedby theCochraneCollaboration fromJanuary 1, 1948to December, 2010. Studies were extracted from thefollowing databases: EMBASE,MEDLINE, HealthStar, PUBMED,CINAHL, PEDro Psycinfo Rehabdata, SUMsearch, Dissertatino,Abstracts International databases, and Cochrane Library.

Data collection process

Study selectionTwo independent reviewers selected studies from theresults of the literature search based on the inclusion and

exclusion criteria outlined in Table 2, noting the reason ifstudies were excluded (see Table 4). The principal assessor(LB) was consulted whenever uncertainty was presented,who also consulted with the rest of the Ottawa Panelexperts (The Ottawa Panel, 2011).

Data extraction and methodological qualityTwo reviewers independently extracted information fromeach included study using standardized data extractionforms focussing on characteristics of the participants,treatment protocols, study design, allocation concealment,comparative results, and the period of data collection.

The Jadad scale (Jadad et al., 1996) was used to assessthe methodological quality of each selected study. Eachstudy was awarded a maximum of five points: 2 points forthe randomization method, 2 points for double blinding,and 1 point for a description of dropouts.

A study assessed with a Jadad scale score of 3 or morepoints (Jadad et al., 1996) is generally considered as beingof high methodological quality. Points for double-blindnesswere rarely givephysical nature of the interventions and thedifficulties in blinding both therapists and participants;greater emphasis was placed on the randomization andwithdrawals categories.

Data analysis

The Cochrane Collaboration methods were used to performstatistical analysis (www.cochrane.org). Weighted meandifferences (WMDs), absolute benefit, and relative differ-ences were calculated for continuous data. Both the Phil-adelphia Panel (The Philadelphia Panel, 2001) and OttawaPanel agreed that improvement was considered clinicallymeaningful if it was 20% or more relative to a control group,which is consistent with the American College of Rheuma-tology having stated that a 20% improvement was clinicallyimportant (Felson et al., 1995), and also with previousstudies on minimum clinically important differences (MCID)

Results

Literature search

A literature search was performed in December 2010 andfound 359 articles related to massage therapy and LBP, ofwhich 44 were deemed potentially relevant. Thirty-threestudieswere excluded (see Table 2) for the following reasons:asymmetrical population randomization (Dishman andBulbulian, 2001), difficult to isolate the effects of massage(Eisenberg et al., 2007; Hsieh et al., 2002; Skillgate et al.,2007; Zaproudina et al., 2009), no control group (Farasynand Meeusen, 2007; Koes et al., 1992; Melzack et al., 1980;Werners et al., 1999; Wilkinson, 1997), combination ofinterventions (Ferrell et al., 1997; Franke et al., 2000;Kankaanpaa et al., 1999; Koes et al., 1993; Konrad et al.,1992; Lidstrom and Zachrisson, 1970; Manniche et al., 1988,1991, 1989), no massage intervention (Ginsberg and Famaey,1987; Godfrey et al., 1984; Hoehler et al., 1981), head tohead comparison of multiple therapies (Hsieh et al., 2004,2006; Mackawan et al., 2007), missing data (Kalauokalaniet al., 2001), healthy study subjects (Kolich et al., 2000),contained only an abstract (Mandala et al., 2001), notrandomized (MelanconandMiller, 2005),massagewasnot theprimary intervention of the study (Pope et al., 1994), hada mixed populations (Skillgate et al., 2007; Walach et al.,

2003), and did not report standard deviations for outcomesof interest (Yip and Tse, 2004). The Ottawa Panel and theresearch assistant teamdetermined that 11 RCTarticleswereeligible; no other type of studies were found that met eligi-bility criteria (Chatchawan et al., 2005; Cherkin et al., 2001,2011; Farasyn et al., 2006; Field et al., 2007; Geisser et al.,2005; Hernandez-Reif et al., 2001; Little et al., 2008; Pooleet al., 2007; Preyde, 2000; Quinn et al., 2008).

Methodological quality

Four out of the 11 included articles received a score of“high quality” (�3): (Cherkin et al., 2011; Little et al.,2008; Preyde, 2000; Quinn et al., 2008); the remainder ofthe articles (7) were of low quality (<3): (Chatchawanet al., 2005; Cherkin et al., 2001; Farasyn et al., 2006;Field et al., 2007; Geisser et al., 2005; Hernandez-Reifet al., 2001; Poole et al., 2007) (see Appendix A and B).

Effectiveness of massage for LBP

The primary focus of this review was to develop recom-mendations based on RCTs with high methodological quality(�3) according to the Jadad scale (Cherkin et al., 2011;Little et al., 2008; Preyde, 2000; Quinn et al., 2008).

Cherkin et al. (2011) (see Appendix A), investigatedstructural massage versus control (usual care) and demon-strated clinically important benefits for decreaseddisability (RMDQ) (see Fig. 1) and symptoms (symptombothersomeness score) (see Fig. 2). When relaxationmassage was compared to control (usual care), clinicallyimportant benefits were demonstrated for improvedsymptoms (symptom bothersomeness score) (see Fig. 4) anddecreased disability (RMDQ) (see Fig. 3).

Little et al. (2008) (see Appendix A) investigated thera-peutic massage versus control (normal care) and demon-strated clinically important benefits for decreaseddisability (RMDQ) (see Fig. 5).

Preyde (2000) (see Appendix A), measured soft-tissuemanipulation versus placebo (sham laser treatment).There were clinically important benefits demonstrated forthe improvement of pain intensity (Present pain index)(see Fig. 6), pain quality (Pain rating index) (see Fig. 8),and decreased disability (RMDQ) (see Fig. 7). Clinicallyimportant benefits were demonstrated but statisticallysignificant for improvement in pain intensity (Present painindex) (see Fig. 6) and pain quality (Pain rating index) (seeFig. 8). This study also compared comprehensive massagetherapy (massage, remedial exercise and posture educa-tion) versus remedial exercise and posture education.There were clinically important benefits demonstrated forthe improvement of pain intensity (Present pain index)(see Fig. 9), pain quality (Pain rating index) (see Fig. 11),and decreased disability (RMDQ) (see Fig. 10).

self-care/education, relaxation therapies, conventionalphysiotherapy, and placebo controls. A total of 37 positiverecommendations were formulated (25 grade A and 12grade Cþ), as were 63 neutral recommendations (49 gradeC and 12 grade D), and 2 negative recommendations (2grade Dþ). Massage therapy should be recommended whenmanaging sub-acute and chronic LBP for immediate posttreatment improvement in pain and disability and shortterm relief when combined with therapeutic exercise andeducation.

Comparisons with previous guidelines

Previously published CPGs recommended massage therapybut did not review supporting evidence in-depth and oftenviewed it as an optional intervention for LBP (Middelkoopet al., 2011; Furlan et al., 2009, 2008; Graham et al.,2008; Chou and Huffman, 2007; Chou et al., 2007;Pillastrini et al., 2011). The conflicting evidence tosupport clear recommendations for massage therapy forLBP might have been due to a lack of a quantitativegrading system and a lack of high quality RCTs. Anotherrecent and updated overview of CPGs on LPB treatmentssuggests that massage therapy has unclear benefits due toinconclusive or conflicting evidence (Pillastrini et al.,2011). In the present study, we found that long termeffects of massage therapy still present conflicting

evidence, but short term effects seems to suggest thatmassage therapy may relieve symptoms of LBP anddecrease associated disability.

Physiological effects

We have concluded that massage therapy is an effectiveintervention to relieve LBP. However, the mechanismunderlying its effectiveness is still unclear. The pressurestimulation associated with touch may increase vagalactivity, which in turn lowers physiological arousal and stresshormones (cortisol levels) (Field, 1998). In a recent study onthe physiological effects of massage, it was confirmed thatphysiological arousal and stress hormones are loweredfollowing massage therapy (Rapaport et al., 2010). Theeffect on pain of pressure stimulus generated by touch is alsoexplained by the gate-control theory (Melzack and Wall,1965), which stipulates that pressure stimulus reaches thespinal cord faster by travelling through large myelinatednerve fibres (Ab fibres) and therefore inhibits nociceptivesignals travelling by slower, less insulated nerve fibres (Adand C fibres). By reaching the spinal cord faster, the pressurestimulus prevents nociceptive signals from reaching thesupra-spinal structures implicated in pain processing. It wasalso observed that massage therapy enhanced immunefunction: Swedish Massage Therapy increased the number ofcirculating lymphocytes, CD 25þ lymphocytes, CD 56þlymphocytes, CD4þlymphocytes, and CD8þlymphocytes(effect sizes from 0.14 to 0.43) (Rapaport et al., 2010).

However, it is important to mention that environmentalfactors may also influence reported pain and functionalimprovements. The relaxing setting, the therapeutic effectsof touch and patient education may also contribute to theefficacy of massage therapy (Cherkin et al., 2011). Acombination of massage therapy and exercise can provide ananalgesic-like effect (Hoffman et al., 2005). Moyer et al.(2004) proposed a psychotherapeutic model that can beextended to massage therapy. It is reported that somepsychological benefits from a therapy may come from all thefactors that form the therapy rather that the treatment itself(Wampold, 2001). “In this model, factors such as a client whohas positive expectations for treatment, a therapist who iswarm and has positive regard for the client, and the devel-opment of an alliance between the therapist and client areconsidered to be more important than adherence toa specific modality of psychotherapy.” (Moyer et al., 2004)

Limitations

Even though this CPG employed a rigorous selectioncriteria and a meticulous methodology, several weak-nesses can be identified. A total of 16 relevant RCTs hadto be excluded because they could not isolate the effectsof massage therapy or because participants also usedmedication or surgery (see Table 4). This reduced thenumber of studies available to support the specific effectof massage therapy. Additionally, it was difficult todetermine the effects of type and dosage of massagebecause the RCTs employed different techniques, dura-tions, and treatment protocols. Most studies of massagetherapy combined various techniques, which were likelyapplied differently by each therapist. Another limitationof this study is the broad definition of massage, which mayexplain why the reflexology study of Quinn et al. (2008)reported conflicting results for disability compared tothe lower back massage study of Cherkin et al. (2011),Little et al. (2008) and Preyde (2000). Finally, only Englishand French articles were selected, which may haveexcluded important information published in otherlanguages.

Clinical implication

Massage therapy should be used as an effective treatmentto relieve sub-acute and chronic LBP symptoms anddecrease disability at immediate post treatment and theeffects may be maintained in the short term if combinedwith remedial exercises and education. Therefore massagetherapy should be part of the treatment options for LBP.

Conclusion

The Ottawa Panel CPGs recommends massage therapy as aneffective intervention to reduce sub-acute and chronic LBPsymptoms and decrease disability at immediate posttreatment and short term relief when combined withtherapeutic exercise and education. Further research isneeded to examine the effects of dosage and technique.Replication of long term effects would allow for greaterconfidence in this treatment.
