Objective To determine the effectiveness of lessons in the Alexandertechnique, massage therapy, and advice from a doctor to takeexercise (exercise prescription) along with nurse deliveredbehavioural counselling for patients with chronic or recurrentback pain.
Design Factorial randomised trial.
Setting 64 general practices in England.
Participants 579 patients with chronic or recurrent low backpain; 144 were randomised to normal care, 147 to massage, 144to six Alexander technique lessons, and 144 to 24 Alexandertechnique lessons; half of each of these groups were randomisedto exercise prescription.
Interventions Normal care (control), six sessions of massage,six or 24 lessons on the Alexander technique, and prescriptionfor exercise from a doctor with nurse delivered behaviouralcounselling.
Main outcome measures Roland Morris disability score (numberof activities impaired by pain) and number of days in pain.
Results Exercise and lessons in the Alexander technique, butnot massage, remained effective at one year (compared with controlRoland disability score 8.1: massage –0.58, 95% confidenceinterval –1.94 to 0.77, six lessons –1.40, –2.77to –0.03, 24 lessons –3.4, –4.76 to –2.03,and exercise –1.29, –2.25 to –0.34). Exerciseafter six lessons achieved 72% of the effect of 24 lessons alone(Roland disability score –2.98 and –4.14, respectively).Number of days with back pain in the past four weeks was lowerafter lessons (compared with control median 21 days: 24 lessons–18, six lessons –10, massage –7) and qualityof life improved significantly. No significant harms were reported.
Conclusions One to one lessons in the Alexander technique fromregistered teachers have long term benefits for patients withchronic back pain. Six lessons followed by exercise prescriptionwere nearly as effective as 24 lessons.

Back pain is a common condition managed in primary care andone of the commonest causes of disability in Western societies.12 As yet few interventions have been proved to substantiallyhelp patients with chronic back pain in the longer term.
Supervised exercise classes—mainly strengthening and stabilisingexercises—probably have moderate benefit for chronic pain.34567 A trial of advice from a doctor to take aerobic exerciseshowed short term benefit for acute pain,8 but the evidenceof longer term benefit for chronic or recurrent pain and forexercise "prescriptions" is lacking.9
Lessons in the Alexander technique offer an individualised approachdesigned to develop lifelong skills for self care that helppeople recognise, understand, and avoid poor habits affectingpostural tone and neuromuscular coordination. Lessons involvecontinuous personalised assessment of the individual patternsof habitual musculoskeletal use when stationary and in movement;paying particular attention to release of unwanted head, neck,and spinal muscle tension, guided by verbal instruction andhand contact, allowing decompression of the spine; help andfeedback from hand contact and verbal instruction to improvemusculoskeletal use when stationary and in movement; and spendingtime between lessons practising and applying the technique (alsosee appendix on bmj.com).
The Alexander technique is thus distinct from manipulation,10back schools,11 and conventional physiotherapy.12 The practiceand theory of the technique, in conjunction with preliminaryfindings of changes in postural tone and its dynamic adaptabilityto changes in load and position,131415 support the hypothesisthat the technique could potentially reduce back pain by limitingmuscle spasm, strengthening postural muscles, improving coordinationand flexibility, and decompressing the spine. A small trial,not fully reported, showed promising short term results forback pain.16 We are not aware of a trial reporting long termresults.
Systematic reviews and a recent trial highlighted the importanceof research to assess the effectiveness of holistic therapeuticmassage171819; we particularly wanted to assess massage asit provides no long term educational element, in contrast withlessons in the Alexander technique.
We determined the effectiveness of six or 24 lessons in theAlexander technique, massage therapy, and advice from a doctorto take exercise (using an exercise prescription) with nursedelivered behavioural counselling for patients with chronicor recurrent back pain.
We recruited 64 general practices in the south and west of Englandin two centres (Southampton and Bristol) on the basis of geographicalavailability of teachers of the Alexander technique and massagetherapists; 152 teachers and therapists agreed to participate.Each practice wrote to a random selection of patients who hadattended with back pain in the past five years (see box forinclusion criteria, mostly similar to the United Kingdom backpain exercise and manipulation trial7 for comparability). Patientswere given information that there was suggestive preliminaryevidence to support each intervention (Alexander technique,massage, and exercise). We recruited patients from 8 July 2002to 22 July 2004.
Inclusion and exclusion criteria of patients with back painin past five years Inclusion criteria: to identify those withsignificant recurrent pain or chronic pain
Presentation inprimary care with low back pain more than three months previously(to exclude first episodes)
Currently scoring 4 or more onthe Roland disability scale
Current pain for three or moreweeks (to exclude recurrence of short duration)
Exclusioncriteria
Previous experience of Alexander technique
Patientsunder 18 and over 65 (serious spinal disease more likely)
Clinicalindicators of serious spinal disease20
Current nerve root pain(below knee in dermatomal distribution), previous spinal surgery,pending litigation (outcome may be different, groups too smallto analyse)
History of psychosis or major alcohol misuse (difficultycompleting outcomes)
Perceived inability to walk 100 m (exercisedifficult)
Randomisation
At the baseline appointment, after informed written consenthad been obtained, participants were randomised to one of eightgroups by the practice nurse telephoning the central coordinatingcentre in Southampton (table 1 and appendix on bmj.com). A statisticianhad prepared a secure program using computer generated randomnumbers so that the next allocation could not be guessed. Foreach practice contributing 10 patients a block of eight numbersexisted, and two were added from a block that supplied fourother practices. Practices were not told how many patients wouldbe recruited to each trial group or informed of the block randomisation.When possible each practice was matched to two Alexander techniqueteachers.
Table 1 Trial groups for patients with chronic or recurrent back pain
Outcome measures
The first primary outcome measure was disability, measured usingthe Roland Morris disability questionnaire. Patients indicatethe number of specified activities or functions limited by backpain2122 (for example, getting out of the house less often,walking more slowly than usual, not doing usual jobs aroundthe house). The scale is designed for self report and has goodvalidation characteristics.23 The second primary outcome measurewas number of days in pain during the past four weeks24 (a fourweek period facilitated recall): this is distinct from intensityof pain or disability.2425
Secondary outcome measures were quality of life, measured usingthe short form 36,26 and secondary measures for back pain21:pain and disability using the Von Korff scale24 and Deyo "troublesomeness"scale,21 overall improvement using health transition,23 andfear avoidance beliefs for physical activity.27
For other measures we asked patients to agree or disagree withstatements on 7 point scales from 0=strongly agree to 7=stronglydisagree. We developed a back health scale (my health has improved,I feel better, I have less back pain, I am able to be more active;Cronbachs =0.96), and a modified enablement instrument28(mean of six items: I am able to cope better with life, I amable to understand my (back) problem better, I am able to copebetter with my (back) problem, I am better able to keep myselfhealthy, I am more confident, I am able to help myself; Cronbachs=0.96).
We measured outcomes at baseline, three months, and one yearusing postal questionnaires, with two mailings to non-respondersand telephone follow-up for a smaller dataset (Roland disabilityscale, days in pain, Von Korff scale, health transition) forthose not responding. Data entry was blind to study group.
Sample size
The sample size was calculated using the Nquery program. TheMedical Research Council back pain working group for the backpain exercise and manipulation trial7 agreed that a 2.5 pointchange on the Roland disability scale was a clinically importantchange in the context of several sessions of manipulation (thatis, a relatively intensive intervention29). In the context ofboth intensive and less intensive interventions we assumed thatchanges in the range 1.5 to 2.5 could therefore be important.This was also justified in our cohort: patients who rated theirback pain as slightly improved after one year compared withthose rating their pain as not improved (a difference of 1 pointon a 7 point scale) had changed Roland disability scores byan additional 2.2 points; 50% of patients achieving this change(a 1.1 point difference) might still be important clinically.We assumed the standard deviation to be 4.730 The limitingelement in the sample size calculations was the Alexander techniquefactor. For =0.01 and 80% power31 and assuming the interventionscould achieve an effect in the clinically important range (sixAlexander technique lessons 1.5 points lower than normal care,massage 2 points lower, and 24 Alexander technique lessons 2.5points lower) then 292 patients were required for the Alexandertechnique factor (73 in each group), or 365 allowing for 20%loss to follow-up. The trial had no cluster design effects asit was individually randomised. We wanted, however, to allowfor clustering effects (of practice, general practitioner, andteacher or therapist) if these proved statistically significant:we included an inflation factor of 1.45, which required 529patients (365x1.45), or 536 in total to provide eight balancedfactorial groups.
Analysis
The analysis plan was agreed in advance by the trial managementgroup. The primary analysis was an analysis of covariance fora factorial study at one year for the primary outcome betweengroups (Roland disability score) and for the secondary outcomes.The days in pain data were skewed so we used non-parametric(quantile) regression. We assessed interaction between factorsbefore reporting the main effects: those of the Alexander techniquefactor are reported controlling for the effect of exercise andthose of the effect of exercise are reported controlling forthe Alexander technique factor. As the study was powered foronly moderately large interactions we also report the individualgroups for the main outcomes at one year. We assessed the statisticalsignificance of clustering by therapist, teacher, and practice,and if these were not significant we did not allow for clusteringin the models.
Most eligible patients who responded agreed to attend for assessment(figure). We wrote to 687 consecutive patients who did not respondto the original invitation, to assess potential eligibilityof non-responders: 553 responded, of whom only six were eligible.A total of 579 people were randomised and completed the baselinequestionnaires, 469 (81%) completed the questionnaires at threemonths, and 463 (80%) the questionnaires at 12 months. Respondersat one year were more likely to have left full time educationlater and to be self employed or homemakers; response was notrelated to baseline Roland disability scores. Including educationand employment status in the final analysis did not alter theestimates or the inferences. No significant cluster effects(practice, therapist or teacher) were found, except for enablement,where a practice clustering effect was found, so only theseresults are presented allowing for clustering. Baseline characteristicswere similar for all variables (table 2) except there were fewerwomen in the Alexander technique groups, probably a chance finding.Including sex in the models did not alter the estimates, sothe results are presented unadjusted.
Table 2 Comparison of groups at baseline according to two intervention factors (Alexander technique, exercise). Values are means (standard deviations) unless stated otherwise
The trial population had predominantly chronic pain—onaverage 243 (SD 131) days of pain in the previous year. Seventynine per cent reported 90 or more days of pain in the previousyear.
Outcomes at three months and one year
Little change occurred in Roland disability score or days inpain in the control group (table 3). Compared with the controlgroup, significant reductions took place for all interventionsfor Roland disability score and days in pain at three months.
Table 3 Outcomes at three months after randomisation. Values are mean differences compared with control group (95% confidence intervals) and P values, unless stated otherwise
The effect of 24 lessons in the Alexander technique was greaterat one year than at three months, with a 42% reduction in Rolanddisability score and an 86% reduction in days in pain comparedwith the control group (table 4). The effect of six lessonswas maintained—a 17% reduction in Roland disability scoreand a 48% reduction in days in pain. Exercise still had a significanteffect on Roland disability score (17% reduction) but not ondays in pain. Massage no longer had an effect on Roland disabilityscore but days in pain was reduced (by 33%). Twenty four lessonsin the Alexander technique also had a significant effect onother outcomes; similar but smaller changes followed six lessons.Massage produced little change in other outcomes except perceptionof overall improvement in back pain (health transition), enablement,and overall satisfaction.
Table 4 Outcomes at one year after randomisation: mean difference compared with control group (95% confidence intervals) unless specified otherwise
Adherence
Good adherence was defined by the trial management group asattending five out of six massage sessions, five out of sixlessons in the group randomised to six lessons in the Alexandertechnique, and 20 out of 24 lessons in the group randomisedto 24 lessons. Good adherence was achieved by 91% (108/119),94% (106/113), and 81% (95/117), respectively. For exerciseprescription—when repeated attendance was not necessaryto increase physical activity—the management group judgedthat adequate adherence was seeing the general practitioneronce (for the prescription) and the nurse at least once (forbehavioural counselling and reinforcement); this was achievedby 76% (211/278) of patients. No meaningful change occurredin the results when only those patients with good adherencewere selected.
Individual groups
The effect of exercise combined with 24 Alexander techniquelessons on Roland disability score and other outcomes was similarto the effect of 24 lessons alone (table 5). The effect of sixlessons followed by exercise prescription on Roland disabilityscore and most other outcomes was almost as good (72% as effective)as 24 lessons.
Table 5 Individual groups one year after randomisation
Adverse events
One patient mentioned that their back pain had been made considerablyworse by massage. No adverse events were reported for exerciseor Alexander technique lessons.
A series of 24 lessons in the Alexander technique taught byregistered teachers provides long term benefits for patientswith chronic or recurrent low back pain. Both six lessons inthe Alexander technique and general practitioner prescriptionfor aerobic exercise with structured behavioural counsellingby a practice nurse were helpful in the long term; classic massageprovided short term benefit. Six lessons in the Alexander techniquefollowed by exercise prescription was almost as effective as24 lessons.
Most patients we contacted were not eligible. The majority ofthe eligible patients who responded to an invitation to participatein the trial were randomised so the results should apply tomost patients with chronic or recurrent back pain. The longprevious duration of pain (79% had pain for >90 days) andthe little change in pain and function in the control groupafter one year (still had significant limitation in activityand pain on most days after one year) suggest that we selecteda predominantly chronic, severely affected, and currently ineffectivelymanaged population. All had attended primary care with backpain in the past—that is, the sample was a clinicallyrelevant population. Since patients were required to be ableto walk, we excluded those most severely disabled by pain.
Adherence was good for both six and 24 lessons in the Alexandertechnique, and for massage compared with adherence in otherback pain intervention trials,7 possibly as a result of theperceived symptomatic benefit. As this was a large pragmatic,multipractice, multiteacher, multitherapist study, the resultsare unlikely to be due to the good work of a small number ofenthusiasts.
The consistent pattern of outcomes at three months and one yearand number of highly significant results suggest that a typeI error (chance) was unlikely. The study was powered to detecta reduction of 1.5 to 2.5 activities affected by back pain.Although the study was underpowered to assess significant interactions(none was found) the results suggest that the effect of exerciseand 24 Alexander technique lessons combined is less than thesum of the two individual effects. We found no evidence of confoundingor bias from losses to follow-up.
The Roland disability scale is one of the best validated selfreport measures for assessing the impact of back pain.2122The effect of intervention on our other primary outcome, reporteddays in pain, is unlikely to be explained by recall bias owingto the large effect size and short period of recall. Recallover such periods is likely to be valid: pain or discomfortfor both short recall periods (2-4 weeks) and longer recallperiods in a variety of conditions compare favourably with diariescompleted prospectively.323334 Any non-differential measurementerror owing to the use of reported days in pain is likely tounderestimate true differences between groups.
Interventions Alexander technique lessons
The previous trial for back pain was smaller and involved oneteacher.16 Our study shows enduring benefits from lessons deliveredby many different teachers. That six sessions of massage weremuch less effective at one year than at three months whereassix lessons in the Alexander technique retained effectivenessat one year shows that the long term benefit of Alexander techniquelessons is unlikely to result from non-specific placebo effectsof attention and touch.
Massage
Massage is helpful in the short term, which supports tentativeconclusions from previous research.1719 Benefit in the longerterm is probably less, which is supported by previous comparisonwith a self care booklet,35 although this trial did find benefitcompared with acupuncture. Acupressure may possibly be moreeffective than the classic massage we used.17
Exercise
Prescription from a general practitioner for unsupervised homebased aerobic exercise (predominantly walking) with follow-upstructured counselling, based on the theory of planned behaviour,36and using behavioural principles, provided modest but usefulbenefits from a relatively brief intervention. Comparison withthe United Kingdom back pain exercise and manipulation trialsuggests the benefits are similar to a supervised exercise schemein the short term, and potentially greater in the long term,since the effect of supervised schemes in that trial was nolonger apparent by 12 months.7 Six lessons on the Alexandertechnique followed by prescription for exercise provided nearlyas much benefit as 24 lessons on the Alexander technique.
Other interventions
A recent study of acupressure in a Chinese orthopaedic clinic37and single practitioner trial of yoga suggest substantial benefitfor back pain,38 but trials were small (<130 participants)with six months of follow-up. Systematic reviews of manipulationsuggest limited benefit,10 and the United Kingdom back painexercise and manipulation trial showed moderate benefits frommanipulation combined with supervised exercise at one year (1.3reduction in Roland disability score). A systematic review suggestedthat strengthening and stabilising exercises are likely to havemoderate benefit4; the more pronounced effects in a recent trial39require confirmation as the follow-up rate was poor (<60%).The finding of possible benefit of acupuncture for quality oflife at 24 months but not 12 months40 requires confirmation,given the negative findings for pain and disability40 and thenegative long term findings reported in the Cochrane review.41The magnitude of benefit we found in the current study—of3 points on the Roland disability score—is likely to beimportant for patients: an improvement of 3 points on the scoremeans that patients have three fewer activities or functionslimited by back pain (such as being able to get out of the houseless often, walking more slowly than usual, not doing usualjobs around the house). This benefit can be provided by 24 lessonsin the Alexander technique, or six lessons combined with exerciseprescription.
What is already known on this topic
Combined manipulation andphysiotherapy-supervised strengthening exercises helps functioningmoderately (1-2 activities no longer limited by back pain)
Preliminaryevidence suggests that massage and lessons in the Alexandertechnique might help in the short term
What this study adds
Sixsessions of massage, prescription for exercise and nurse counselling,six lessons in the Alexander technique, and 24 lessons helpedwith back pain and functioning at three months
Lessons in theAlexander technique still had a beneficial effect on pain andfunctioning after 12 months
Six lessons in the Alexander techniquefollowed by exercise prescription are nearly as effective as24 lessons
