The effectiveness of sub-group specific manual therapy for low back pain : a systematic review.

BACKGROUND Manual therapy is frequently used to treat low back pain (LBP), but evidence of its effectiveness is limited. One explanation may be sample heterogeneity and inadequate sub-grouping of participants in randomized controlled trials (RCTs) where manual therapy has not been targeted toward those likely to respond. OBJECTIVES To determine the effectiveness of specific manual therapy provided to sub-groups of participants identified as likely to respond to manual therapy. DATA SOURCES A systematic search of electronic databases of MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled trials (CENTRAL). TRIAL ELIGIBILITY CRITERIA: RCTs on manual therapy for participants identified as belonging to a sub-group of LBP likely to respond to manual therapy were included. TRIAL APPRAISAL AND SYNTHESIS METHODS: Identified trials were assessed for eligibility. Data from included trials were extracted by two authors independently. Risk of bias in each trial was assessed using the PEDro scale and the overall quality of evidence rated according to the GRADE domains. Treatment effect sizes and 95% confidence intervals were calculated for pain and activity. RESULTS Seven RCTs were included in the review. Clinical and statistical heterogeneity precluded meta-analysis. Significant treatment effects were found favouring sub-group specific manual therapy over a number of comparison treatments for pain and activity at short and intermediate follow-up. However, the overall GRADE quality of evidence was very low. CONCLUSIONS This review found preliminary evidence supporting the effectiveness of sub-group specific manual therapy. Further high quality research on LBP sub-groups is required.

Efficacy of Directional Preference Management for Low Back Pain: A Systematic Review

Background Providing specific treatment based on symptom response for people with low back pain (LBP) and a directional preference (DP) is a widely used treatment approach. The efficacy of treatment using the principles of directional preference management (DPM) for LBP is unclear. Objective The purpose of this study was to determine the efficacy of treatment using the principles of DPM for people with LBP and a DP. Methods Computer databases were searched for randomized controlled trials (RCTs) published in English up to January 2010. Only RCTs investigating DPM for people with LBP and a DP were included. Outcomes for pain, back specific function, and work participation were extracted. Results Six RCTs were included in this review. Five were considered high quality. Clinical heterogeneity of the included trials prevented meta-analysis. GRADE quality assessment revealed mixed results; however, moderate evidence was identified that DPM was significantly more effective than a number of comparison treatments for pain, function, and work participation at short-term, intermediate-term, and long-term follow-ups. No trials found that DPM was significantly less effective than comparison treatments. Conclusions Although this systematic review showed mixed results, some evidence was found supporting the effectiveness of DPM when applied to participants with a DP, particularly at short-term and intermediate-term follow-ups. Further high-quality RCTs are warranted to evaluate the effect of DPM applied to people with LBP and a DP.

Individualised physiotherapy as an adjunct to guideline-based advice for low back disorders in primary care: a randomised controlled trial

Background Many patients with low-back disorders persisting beyond 6 weeks do not recover. This study investigates whether individualised physiotherapy plus guideline-based advice results in superior outcomes to advice alone in participants with low-back disorders. Methods This prospective parallel group multicentre randomised controlled trial was set in 16 primary care physiotherapy practices in Melbourne, Australia. Random assignment resulted in 156 participants receiving 10 sessions of physiotherapy that was individualised based on pathoanatomical, psychosocial and neurophysiological barriers to recovery combined with guideline-based advice, and 144 participants receiving 2 sessions of physiotherapist-delivered advice alone. Primary outcomes were activity limitation (Oswestry Disability Index) and numerical rating scales for back and leg pain at 5, 10, 26 and 52 weeks postbaseline. Analyses were by intention-to-treat using linear mixed models. Results Between-group differences showed significant effects favouring individualised physiotherapy for back and leg pain at 10 weeks (back: 1.3, 95% CI 0.8 to 1.8; leg: 1.1, 95% CI 0.5 to 1.7) and 26 weeks (back: 0.9, 95% CI 0.4 to 1.4; leg: 1.0, 95% CI 0.4 to 1.6). Oswestry favoured individualised physiotherapy at 10 weeks (4.7; 95% CI 2.0 to 7.5), 26 weeks (5.4; 95% CI 2.6 to 8.2) and 52 weeks (4.3; 95% CI 1.4 to 7.1). Responder analysis at 52 weeks showed participants receiving individualised physiotherapy were more likely to improve by a clinically important amount of 50% from baseline for Oswestry (relative risk (RR=1.3) 1.5; 95% CI 1.2 to 1.8) and back pain (RR 1.3; 95% CI 1.2 to 1.8) than participants receiving advice alone. Conclusions 10 sessions of individualised physiotherapy was more effective than 2 sessions of advice alone in participants with low-back disorders of ≥6 weeks and ≤6 months duration. Between-group changes were sustained at 12 months for activity limitation and 6 months for back and leg pain and were likely to be clinically significant.

Specific treatment of problems of the spine (STOPS): design of a randomised controlled trial comparing specific physiotherapy versus advice for people with subacute low back disorders

BackgroundLow back disorders are a common and costly cause of pain and activity limitation in adults. Few treatment options have demonstrated clinically meaningful benefits apart from advice which is recommended in all international guidelines. Clinical heterogeneity of participants in clinical trials is hypothesised as reducing the likelihood of demonstrating treatment effects, and sampling of more homogenous subgroups is recommended. We propose five subgroups that allow the delivery of specific physiotherapy treatment targeting the pathoanatomical, neurophysiological and psychosocial components of low back disorders. The aim of this article is to describe the methodology of a randomised controlled trial comparing specific physiotherapy treatment to advice for people classified into five subacute low back disorder subgroups.Methods/DesignA multi-centre parallel group randomised controlled trial is proposed. A minimum of 250 participants with subacute (6 weeks to 6 months) low back pain and/or referred leg pain will be classified into one of five subgroups and then randomly allocated to receive either physiotherapy advice (2 sessions over 10 weeks) or specific physiotherapy treatment (10 sessions over 10 weeks) tailored according to the subgroup of the participant. Outcomes will be assessed at 5 weeks, 10 weeks, 6 months and 12 months following randomisation. Primary outcomes will be activity limitation measured with a modified Oswestry Disability Index as well as leg and back pain intensity measured on separate 0-10 Numerical Rating Scales. Secondary outcomes will include a 7-point global rating of change scale, satisfaction with physiotherapy treatment, satisfaction with treatment results, the Sciatica Frequency and Bothersomeness Scale, quality of life (EuroQol-5D), interference with work, and psychosocial risk factors (Orebro Musculoskeletal Pain Questionnaire). Adverse events and co-interventions will also be measured. Data will be analysed according to intention to treat principles, using linear mixed models for continuous outcomes, Mann Whitney U tests for ordinal outcomes, and Chi-square, risk ratios and risk differences for dichotomous outcomes.DiscussionThis trial will determine the difference in outcomes between specific physiotherapy treatment tailored to each of the five subgroups versus advice which is recommended in guidelines as a suitable treatment for most people with a low back disorder.Trial registrationAustralia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12609000834257.

The effectiveness of physiotherapy functional restoration for post-acute low back pain: A systematic review

BACKGROUND The effectiveness of multidisciplinary treatment for post-acute (>6 weeks) low back pain (LBP) has been established. Physiotherapists have sufficient training to conduct less intensive functional restoration. The effectiveness of physiotherapy functional restoration (PFR) has not been evaluated using current systematic review methodology. OBJECTIVES To determine the effects of PFR for post-acute LBP. DATA SOURCES Electronic databases searched include: MEDLINE, EMBASE, CINAHL, PsycINFO, PEDro and Cochrane CENTRAL. TRIAL ELIGIBILITY CRITERIA: Randomised controlled trials of physiotherapy treatment for post-acute LBP combining exercise and cognitive-behavioural intervention compared with other intervention, no intervention or placebo. TRIAL APPRAISAL AND SYNTHESIS METHODS: Two authors independently extracted data. Risk of bias was assessed using the PEDro scale and overall quality of the body of evidence was assessed using GRADE (Grading of Recommendations, Assessment, Development and Evaluation). Treatment effect sizes and 95% confidence intervals were calculated for pain, function and sick leave. RESULTS Sixteen trials were included. Heterogeneity prevented meta-analysis for most comparisons. Meta-analyses showed moderate to high quality evidence of significant but small effects favouring PFR compared with advice for intermediate term function and intermediate and long term pain. There was however low to moderate quality evidence that PFR was no more effective than a range of other treatment types. Heterogeneous trials frequently contributed to very low quality evidence. CONCLUSIONS Moderate to high quality evidence was found of small effects favouring PFR compared with advice. Preliminary evidence suggested PFR is not different to other treatment types. Further high quality research is required replicating existing trial protocols.

A classification and treatment protocol for low back disorders Part 2 – Directional preference management for reducible discogenic pain

AbstractBackground: It has been widely recommended that clinical trials on people with low back disorders should have a greater focus on subgroup specific treatment in order to increase the likelihood of clinically meaningful effects being demonstrated. The McKenzie approach to assessing and treating patients with a directional preference is a potentially useful and widely used clinical method in providing specific treatment. Studies to date have not used a clearly defined and appropriately detailed clinical protocol for the McKenzie approach that is reproducible in the clinical or research setting.Objectives: This paper presents a detailed classification and treatment protocol for people with clinical features thought to be indicative of reducible discogenic pain with a directional preference that is responsive to mechanical loading strategies.Discussion: A pathoanatomical interpretation of the McKenzie approach, classification principles and particular treatment components in the clinical protocol are d...Abstract Background: It has been widely recommended that clinical trials on people with low back disorders should have a greater focus on subgroup specific treatment in order to increase the likelihood of clinically meaningful effects being demonstrated.

A classification and treatment protocol for low back disorders Part 3 – Functional restoration for intervertebral disc related disorders

Abstract Background: It has been widely recommended that clinical trials on people with low back disorders (LBDs) should have a greater focus on subgroup specific treatment in order to increase the likelihood of clinically meaningful effects being demonstrated. Functional restoration is a treatment approach that has demonstrated some evidence of effectiveness in subacute and chronic LBDs. However, studies to date have not used a clearly defined and appropriately detailed clinical protocol or applied the treatment to homogenous pathoanatomical based subgroups. Objectives: This paper presents a detailed classification and treatment protocol for people with LBDs and clinical features thought to be indicative of non-reducible discogenic pain or disc herniation with associated radiculopathy. Discussion: A pathoanatomical interpretation of traditional functional restoration, classification principles and particular treatment components in the clinical protocol are discussed. Conclusion: The described clinical protocol will be used in the Specific Treatment for Problems of the Spine trials comparing specific physiotherapy to evidence-based advice.AbstractBackground: It has been widely recommended that clinical trials on people with low back disorders (LBDs) should have a greater focus on subgroup specific treatment in order to increase the likelihood of clinically meaningful effects being demonstrated.

Outcomes and adverse events from physiotherapy functional restoration for lumbar disc herniation with associated radiculopathy

Purpose. To report the outcomes and adverse events of people diagnosed with lumbar disc herniation with associated radiculopathy (LDHR) who were treated with a physiotherapy functional restoration programme. Method. Data on functional outcome (Oswestry score), work status, global rating of change, and adverse events were extracted from the files of all people with LDHR treated by three physiotherapists using functional restoration principles from 2001 to 2009. Results. Ninety-five participants were included. The Oswestry score reduced by a mean of 15.9 (95%% CI, 11.8–20.1) points between baseline and discharge following a mean (SD) of 8.7 (9.4) months of treatment. The proportion of participants working full-time increased from 37%% to 67%% between baseline and discharge (p  <  0.001). Eighty per cent of participants reported overall improvement between baseline and discharge on the global rating of change scale (p  <  0.001). Minor adverse events were reported by eight (8%%) participants, while one (1%%) participant developed adhesive capsulitis. Conclusion. People with LDHR who undertook a physiotherapy functional restoration programme achieved significant improvements in Oswestry disability scores, work status, and global rating of change, with few adverse events reported. A randomised controlled trial is warranted to determine the efficacy of functional restoration for people with this condition.

Individualized functional restoration as an adjunct to advice for lumbar disc herniation with associated radiculopathy. A preplanned subgroup analysis of a randomized controlled trial

BACKGROUND CONTEXT Physical therapy is commonly sought by people with lumbar disc herniation and associated radiculopathy. It is unclear whether physical therapy is effective for this population. PURPOSE To determine the effectiveness of physical therapist-delivered individualized functional restoration as an adjunct to guideline-based advice in people with lumbar disc herniation and associated radiculopathy. STUDY DESIGN This is a preplanned subgroup analysis of a multicenter parallel group randomized controlled trial. PATIENT SAMPLE The study included 54 participants with clinical features of radiculopathy (6-week to 6-month duration) and imaging showing a lumbar disc herniation. OUTCOME MEASURES Primary outcomes were activity limitation (Oswestry Disability Index) and separate 0-10 numerical pain rating scales for leg pain and back pain. Measures were taken at baseline and at 5, 10, 26, and 52 weeks. METHODS The participants were randomly allocated to receive either individualized functional restoration incorporating advice (10 sessions) or guideline-based advice alone (2 sessions) over a 10-week period. Treatment was administered by 11 physical therapists at private clinics in Melbourne, Australia. RESULTS Between-group differences for activity limitation favored the addition of individualized functional restoration to advice alone at 10 weeks (7.7, 95% confidence interval [CI] 0.3-15.1) and 52 weeks (8.2, 95% CI 0.7-15.6), as well as back pain at 10 weeks (1.4, 95% CI 0.2-2.7). There were no significant differences between groups for leg pain at any follow-up. Several secondary outcomes also favored individualized functional restoration over advice. CONCLUSIONS In participants with lumbar disc herniation and associated radiculopathy, an individualized functional restoration program incorporating advice led to greater reduction in activity limitation at 10- and 52-week follow-ups compared with guideline-based advice alone. Although back pain was significantly reduced at 10 weeks with individualized functional restoration, this effect was not maintained at later timepoints, and there were no significant effects on leg pain, relative to guideline-based advice.

Individualized Physical Therapy is Cost Effective Compared to Guideline-Based Advice for People with Low Back Disorders.

Study Design. A cost-utility analysis within a randomized controlled trial was conducted from the health care perspective. Objective. The aim of this study was to determine whether individualized physical therapy incorporating advice is cost-effective relative to guideline-based advice alone for people with low back pain and/or referred leg pain (≥6 weeks, ⩽6 months duration of symptoms). Summary of Background Data. Low back disorders are a burdensome and costly condition across the world. Cost-effective treatments are needed to address the global burden attributable to this condition. Methods. Three hundred participants were randomly allocated to receive either two sessions of guideline-based advice alone (n = 144), or 10 sessions of individualized physical therapy targeting pathoanatomical, psychosocial and neurophysiological factors, and incorporating advice (n = 156). Data relating to health care costs, health benefits (EuroQol-5D) and work absence were obtained from participants via questionnaires at 5, 10, 26, and 52-week follow-ups. Results. Total health care costs were similar for both groups: mean difference
