Multidisciplinary bio-psycho-social rehabilitation for chronic low back pain

Effects of nurse-led motivational interviewing of patients with chronic musculoskeletal pain in preparation of rehabilitation treatment (PREPARE) on societal participation, attendance level, and cost-effectiveness: study protocol for a randomized controlled trial

Background

Non-adherence and drop-out are major problems in pain rehabilitation. For patients with various health problems, motivational interviewing (MI) has shown promising effects to tackle these problems. In chronic pain patients, the effectiveness of MI is however unknown. Therefore, a MI-based pre-pain rehabilitation intervention (MIP) addressing motivation, expectations, and beliefs has been developed to prepare eligible patients for rehabilitation treatment.

Methods/design

Study design: A parallel randomized controlled trial including two interventions: a motivational interviewing pre-pain rehabilitation intervention (MIP) and a usual care (UC) control arm. Follow-up will be 6 months after completion of rehabilitation treatment.

Study population: One hundred and sixty (n = 80 per arm) patients with chronic non-specific musculoskeletal pain visiting an outpatient rehabilitation department, who are eligible to participate in an outpatient cognitive behavioral pain rehabilitation program.

Intervention: MIP consists of two sessions to prepare and motivate the patient for pain rehabilitation treatment and its bio psychosocial approach. UC consists of information and education about the etiology and the general rehabilitation approach of chronic pain. Both the MIP and UC contain two sessions of 45 to 60 minutes each.

Objective: The aim of the current study is to evaluate the effectiveness of MIP compared to UC in terms of an increase in the long-term level of societal participation and decrease of drop-out during rehabilitation treatment.

Main study endpoints: Primary outcome is the change in level of participation (according to the ICF-definition: ‘involvement in a life situation’) 6 months after completion of rehabilitation treatment. Secondary outcomes are adherence and treatment drop-out, disability, pain intensity, self-reported main complaints, (pain-specific) self-efficacy, motivation, and quality of life. Costs are calculated including the costs of the pre-treatment intervention, productivity losses, and healthcare utilization. Potential moderators and active ingredients of MI are explored. For the process evaluation, parameters such as MI fidelity, feasibility, and experiences are explored.

Discussion

The results of this study will provide evidence on the effectiveness of this MI-based pre-treatment in pain rehabilitation. Furthermore, a cost-effectiveness analysis and exploration of moderating and working mechanisms of MI and an extensive process evaluation takes place.

Sustained employability of workers in a production environment: design of a stepped wedge trial to evaluate effectiveness and cost-benefit of the POSE program

Background

Sustained employability and health are generating awareness of employers in an aging and more complex work force. To meet these needs, employers may offer their employees health surveillance programs, to increase opportunities to work on health and sustained employability. However, evidence for these health surveillance programs is lacking. The FLESH study (Functional Labour Evaluation for Sustained Health and employment) was developed to evaluate a comprehensive workers’ health promotion program on its effectiveness, cost-benefit, and process of the intervention.

Methods

The study is designed as a cluster randomised stepped wedge trial with randomisation at company plant level and is carried out in a large meat processing company. Every contracted employee is offered the opportunity to participate in the POSE program (Promotion Of Sustained Employability). The main goals of the POSE program are 1) providing employee’s insight into their current employability and health status, 2) offering opportunities to improve employability and decrease health risks and 3) improving employability and health sustainably in order to keep them healthy at work. The program consists of a broad assessment followed by a counselling session and, if needed, a tailored intervention. Measurements will be performed at baseline and will be followed up at 20, 40, 60, 80, 106 and 132 weeks. The primary outcome measures are work ability, productivity and absenteeism. Secondary outcomes include health status, vitality, and psychosocial workload. A cost-benefit study will be conducted from the employers’ perspective. A process evaluation will be conducted and the satisfaction of employer and employees with the program will be assessed.

Discussion

This study provides information on the effectiveness of the POSE program on sustained employment. When the program proves to be effective, employees benefit by improved work ability, and health. Employers benefit from healthier employees, reduced sick leave (costs) and higher productivity. The study can expose key elements for a successful implementation and execution of the POSE program and may serve as an example to other companies inside and outside the industry.

Short-term response of hip mobilizations and exercise in individuals with chronic low back pain: a case series

STUDY DESIGN

A case series of consecutive patients with chronic low back pain.

BACKGROUND AND PURPOSE

In patients with chronic low back pain (CLBP), the importance of impairments at the hip joints is unclear. However, it has been postulated that impairments at the hip joints may contribute to CLBP. The purpose of this case series was to investigate the short-term outcomes in patients with CLBP managed with impairment-based manual therapy and exercise directed at the hip joints.

METHODS

EIGHT CONSECUTIVE PATIENTS (MEAN AGE: 43·9 years) with a primary report of CLBP (>6 months) without radiculopathy were treated with a standardized approach of manual physical therapy and exercise directed at bilateral hip impairments for a total of three sessions over approximately 1 week. At initial examination, all patients completed a numeric rating pain scale (NPRS), Oswestry disability index (ODI), fear-avoidance beliefs questionnaire (FABQ), and patient-specific functional scale (PSFS). At the second and third treatment sessions, each patient completed all outcome measures as well as the Global Rating of Change (GROC).

RESULTS

Five of the eight (62·5%) patients reported 'moderately better' or higher (>+4) on the GROC at the third session, indicating a moderate improvement in self-reported symptoms. These five individuals also experienced a 24·4% reduction in ODI scores.

DISCUSSION

This case series suggests that an impairment-based approach directed at the hip joints may lead to improvements in pain, function, and disability in patients with CLBP. A neurophysiologic mechanism may be a plausible explanation regarding the clinical outcomes of this study. A larger, well-controlled trial is needed to determine the potential effectiveness of this approach with patients with CLBP.

Intensive interdisciplinary outpatient pain management program for chronic back pain: a pilot study

BACKGROUND

Chronic back pain is relatively resistant to unimodal therapy regimes. The aim of this study was to introduce and evaluate the short-term outcome of a three-week intensive multidisciplinary outpatient program for patients with back pain and sciatica, measured according to decrease of functional impairment and pain.

METHODS

The program was designed for patients suffering from chronic back pain to provide intensive interdisciplinary therapy in an outpatient setting, consisting of interventional injection techniques, medication, exercise therapy, back education, ergotherapy, traction, massage therapy, medical training, transcutaneous electrical nerve stimulation, aquatraining, and relaxation.

RESULTS

Based on Oswestry Disability Index (ODI) and Numeric Rating Scale (NRS) scores, a significant improvement in pain intensity and functionality of 66.83% NRS and an ODI of 33.33% were achieved by our pain program within 3 weeks.

CONCLUSION

This paper describes the organization and short-term outcome of an intensive multidisciplinary program for chronic back pain on an outpatient basis provided by our orthopedic department, with clinically significant results.

A short, intensive cognitive behavioral pain management program reduces health-care use in patients with chronic low back pain: two-year follow-up results of a prospective cohort

PURPOSE

Cognitive behavioral interventions are recommended as non-invasive treatment options for patients with chronic low back pain (CLBP). However, most treatment effects are small and short-lived. Although a 2-week intensive pain management program for patients with CLBP seems to be effective, the long-term results are not known. The purpose of this study is to evaluate the stability of the 2-year follow-up results and whether this is reflected in the use of health-care services.

METHODS

A prospective cohort study was performed. Pre-treatment characteristics of patients and data of outcomes obtained at 1-year follow-up were used. At 2-year follow-up a structured interview was conducted following the principles of a post-marketing survey. Outcomes included daily functioning, quality of life, current intensity of pain, disturbance of pain during daily activities, and indicators of the use of pain medication and health-care services.

RESULTS

Of the 90 eligible patients 85 (94%) participated in the post-marketing survey. The 1-year clinical relevant effects are maintained at 2-year follow-up. Effect sizes for functioning and quality of life were large. More than 65% reached preset minimal clinically important differences. At pre-treatment all patients consulted their general practitioner (GP) and medical specialist (MS). At 2-year follow-up 73% reported having consulted neither a GP nor an MS during the previous year. Most of the patients indicated not to use any pain medication (57%) and the percentage patients using opioids have decreased (14%). Moreover, 81% reported to be at work.

CONCLUSIONS

The gained results from selected and motivated patients with longstanding CLBP at 1-year follow-up are stable at 2-year follow-up. Above all, most of the participants are at work and results indicate that the use of both pain medication and health care have decreased substantially.

A model of integrative care for low-back pain

OBJECTIVES

While previous studies focused on the effectiveness of individual complementary and alternative medical (CAM) therapies, the value of providing patients access to an integrated program involving multiple CAM and conventional therapies remains unknown. The objective of this study is to explore the feasibility and effects of a model of multidisciplinary integrative care for subacute low-back pain (LBP) in an academic teaching hospital.

DESIGN

This was a pilot randomized trial comparing an individualized program of integrative care (IC) plus usual care to usual care (UC) alone for adults with LBP.

SUBJECTS

Twenty (20) individuals with LPB of 3-12 weeks' duration were recruited from an occupational health clinic and community health center.

INTERVENTIONS

Participants were randomized to 12 weeks of individualized IC plus usual care versus UC alone. IC was provided by a trained multidisciplinary team offering CAM therapies and conventional medical care.

OUTCOME MEASURES

The outcome measures were symptoms (pain, bothersomeness), functional status (Roland-Morris score), SF-12, worry, and difficulty performing three self-selected activities.

RESULTS

Over 12 weeks, participants in the IC group had a median of 12.0 visits (range 5-25). IC participants experienced significantly greater improvements at 12 weeks than those receiving UC alone in symptom bothersomeness (p=0.02) and pain (p=0.005), and showed greater improvement in functional status (p=0.08). Rates of improvement were greater for patients in IC than UC in functional status (p=0.02), bothersomeness (p=0.002), and pain scores (p=0.001). Secondary outcomes of self-selected most challenging activity, worry, and the SF-12 also showed improvement in the IC group at 12 weeks. These differences persisted at 26 weeks, but were no longer statistically significant.

CONCLUSIONS

It was feasible for a multidisciplinary, outpatient IC team to deliver coordinated, individualized intervention to patients with subacute LBP. Results showed a promising trend for benefit of treating patients with persistent LBP with this IC model, and warrant evaluation in a full-scale study.

Anxiety and depression are independent predictors of quality of life of patients with chronic musculoskeletal pain

We examined the relative impact of baseline anxiety, depression and fear of movement on health related quality of life at 12-month follow-up after a multidisciplinary pain management programme. One hundred and eleven patients who had chronic musculoskeletal pain (mean age 45 years, 65% women) attended during 2003–2005 a multidisciplinary three-phase pain management programme with a total time frame of six to seven months, totalling 19 days. The Beck Anxiety Inventory was used to rate anxiety, the Beck Depression Inventory depression, the Tampa Scale of Kinesiophobia fear of movement. The generic 15D questionnaire was used to assess health related quality of life. Baseline data were collected at admission, follow-up data at 12 months. Mean health related quality of life increased significantly from baseline to 12-month follow-up. Anxiety at baseline predicted significant negative change in the health related quality of life, depression predicted significant positive change in the health related quality of life. Fear of movement did not predict any significant change in the health related quality of life. We concluded that patients with chronic musculoskeletal pain and mild to moderate depression benefit from a multidisciplinary pain management programme in contrast to anxious patients. The findings imply further research with bigger sample sizes, other than HRQoL outcome measures as well as with other groups of patients.

Pain management in the context of workers compensation: a case study

The clinical management of chronic pain is a biopsychosocial challenge in itself; however, when the pain occurs in the context of workers compensation, there is even greater clinical complexity. A review of the literature shows that patients being treated for chronic pain under workers compensation are generally more distressed and have poorer outcomes both clinically and vocationally than non-compensated patients. A range of factors is identified to explain these differences, including operation of the system itself. However, a case study is presented involving a 49-year-old woman with chronic neck pain, whose clinical history illustrates how workers compensation can negatively influence outcomes, but where successful rehabilitation is also possible.

Psychological factors unrelated to activity level in patients with chronic musculoskeletal pain

BACKGROUND

Enhancement of physical activities is an important goal in rehabilitation programmes for patients with chronic musculoskeletal pain (CMP). A relationship between activity level and psychological factors is suggested but studied scarcely.

AIM

To explore the relationship between the activity level and psychological factors in patients with CMP.

METHODS

Study design is cross-sectional, explorative. Participants are patients with CMP, included for outpatient multidisciplinary pain rehabilitation.

MEASURES

Activity level was measured by the RT3 accelerometer during 1 week; pain intensity was measured with a 100-mm visual analogue scale; depression, somatization and distress were measured with Symptom Checklist-90-Revised (SCL-90-R), coping strategy with the Utrecht Coping List (UCL, scales active coping, passive coping, avoiding), fear of movement measured with Tampa Scale of Kinesiophobia (TSK), scale activity avoidance. Depending on data distribution, correlations between the mean number of activity counts and psychological factors were tested with Pearson or Spearman correlation coefficients.

RESULTS

Fifty three patients were included: age mean 39.9 years [standard deviation (SD) 11.3]; activity counts per day mean 198,243 (SD 78,000); pain intensity mean 58 (SD 27.7); SCL-90-R mean 149.4 (SD 42.5); UCL active coping mean 17.9 (SD 3.7); UCL passive coping mean 12.3 (SD 3.7); UCL avoiding mean 15.3 (SD 3.0); TSK total mean 35.4 (SD 7.4); TSK activity avoidance mean 16.9 SD (4.7). Correlations between psychological factors and the mean number of activity counts per day ranged from r = -0.27 to r = 0.01 and were all non-significant (p ≥ 0.05).

CONCLUSION

Psychological factors and activity level were unrelated in patients with CMP.

A qualitative study on the role of cultural background in patients' perspectives on rehabilitation

Background

Low back pain (LBP) is one of the major concerns in health care. In Switzerland, musculoskeletal problems represent the third largest illness group with 9.4 million consultations per year. The return to work rate is increased by an active treatment program and saves societal costs. However, results after rehabilitation are generally poorer in patients with a Southeast European cultural background than in other patients. This qualitative research about the rehabilitation of patients with LBP and a Southeast European cultural background, therefore, explores possible barriers to successful rehabilitation.

Methods

We used a triangulation of methods combining three qualitative methods of data collection: 13 semi-structured in-depth interviews with patients who have a Southeast European cultural background and live in Switzerland, five semi-structured in-depth interviews and two focus groups with health professionals, and a literature review. Between June and December 2008, we recruited participants at a Rehabilitation Centre in the German-speaking part of Switzerland.

Results

To cope with pain, patients prefer passive strategies, which are not in line with recommended coping strategies. Moreover, the families of patients tend to support passive behaviour and reduce the autonomy of patients. Health professionals and researchers propagate active strategies including activity in the presence of pain, yet patients do not consider psychological factors contributing to LBP. The views of physicians and health professionals are in line with research evidence demonstrating the importance of psychosocial factors for LBP. Treatment goals focusing on increasing daily activities and return to work are not well understood by patients partly due to communication problems, which is something that patients and health professionals are aware of. Additional barriers to returning to work are caused by poor job satisfaction and other work-related factors.

Conclusions

LBP rehabilitation can be improved by addressing the following points. Early management of LBP should be activity-centred instead of pain-centred. It is mandatory to implement return to work management early, including return to adapted work, to improve rehabilitation for patients. Rehabilitation has to start when patients have been off work for three months. Using interpreters more frequently would improve communication between health professionals and patients, and reduce misunderstandings about treatment procedures. Special emphasis must be put on the process of goal-formulation by spending more time with patients in order to identify barriers to goal attainment. Information on the return to work process should also include the financial aspects of unemployment and disability.

Analysis of 22,655 presentations with back pain to Perth emergency departments over five years

Background

Back pain is a significant cause of disability in the community, but the impact on Emergency Departments (EDs) has not been formally studied. Patients with back pain often require significant time and resources in the ED.

Aims

To examine the characteristics of patients presenting with back pain to the ED, including final diagnosis, demographics of those attending and temporal distribution of presentations.

Methods

Emergency presentations in the metropolitan area of Perth, Western Australia, for 2000-2004 were searched using a linked database covering all the major hospitals (Emergency Care Hospitalisation and Outcome Study database). All presentations with the triage code for back pain were extracted and analysed.

Results

A total of 22,655 presentations with back pain were identified, representing 1.9% of total presentations. Simple muscular or non-specific back pain accounted for only 43.8% of presentations, with other causes such as renal colic and pyelonephritis accounting for the majority. The young (<15 years old) and elderly (>75 years old) were more likely to have non-muscular causes for their back pain. Muscular back pain presentations occurred mostly between 0800 and 1600, with high proportions presenting on the weekends. Patients with simple muscular back pain spent a mean of 4.4 h in the ED, representing a significant outlay of resources.

Conclusion

Back pain has a significant impact on EDs, and staff should be alert for another pathology presenting as back pain. There is a need for multidisciplinary back pain teams to be available 7 days a week, but only during the day.

Management of pain induced by exercise and mobilization during physical therapy programs: views of patients and care providers

BACKGROUND

The expectations of patients for managing pain induced by exercise and mobilization (PIEM) have seldom been investigated. We identified the views of patients and care providers regarding pain management induced by exercise and mobilization during physical therapy programs.

METHODS

We performed a qualitative study based on semi-structured interviews with a stratified sample of 12 patients (7 women) and 14 care providers (6 women): 4 general practitioners [GPs], 1 rheumatologist, 1 physical medicine physician, 1 geriatrician, 2 orthopedic surgeons, and 5 physical therapists.

RESULTS

Patients and care providers have differing views on PIEM in the overall management of the state of disease. Patients' descriptions of PIEM were polymorphic, and they experienced it as decreased health-related quality of life. The impact of PIEM was complex, and patient views were sometimes ambivalent, ranging from denial of symptoms to discontinuation of therapy. Care providers agreed that PIEM is generally not integrated in management strategies. Care providers more often emphasized the positive and less often the negative dimensions of PIEM than did patients. However, the consequences of PIEM cited included worsened patient clinical condition, fears about physical therapy, rejection of the physical therapist and refusal of care. PIEM follow-up is not optimal and is characterized by poor transmission of information. Patients expected education on how better to prevent stress and anxiety generated by pain, education on mobilization, and adaptations of physical therapy programs according to pain intensity.

CONCLUSION

PIEM management could be optimized by alerting care providers to the situation, improving communication among care providers, and providing education to patients and care providers.

The impact of enrollment in a specialized interdisciplinary neuropathic pain clinic

BACKGROUND

Chronic pain clinics have been created because of the increasing recognition of chronic pain as a very common, debilitating condition that requires specialized care. Neuropathic pain (NeP) is a multifaceted, specialized form of chronic pain that often requires input from multiple disciplines for assessment and management.

OBJECTIVE

To determine the impact of an interdisciplinary clinic for evaluation and treatment of patients with NeP.

METHODS

Patients with heterogeneous etiologies for NeP were prospectively evaluated using an interdisciplinary approach every six months. Diagnostic evaluation, comorbidity evaluation, education, and pharmacological and⁄or nonpharmacological management were completed. Severity (visual analogue scale) and features of pain (Modified Brief Pain Inventory), sleep difficulties (Medical Outcomes Study - Sleep Scale), mood⁄anxiety disruption (Hospital Anxiety and Depression Scale), quality of life (European Quality-of-Life Five-Domain index), health care resources use, patient satisfaction (Pain Treatment Satisfaction Scale and Neuropathic Pain Symptom Inventory) and self-perceived change in well-being (Patient Global Impression of Change scale) were examined at each visit.

RESULTS

Pain severity only decreased after one year of follow-up, while anxiety and quality- of-life indexes improved after six months. Moderate improvements of sleep disturbance, less frequent medication use and reduced health care resource use were observed during enrollment at the NeP clinic.

DISCUSSION

Despite the limitations of performing a real-world, uncontrolled study, patients with NeP benefit from enrollment in a small interdisciplinary clinic. Education and a complete diagnostic evaluation are hypothesized to lead to improvements in anxiety and, subsequently, pain severity. Questions remain regarding the long-term maintenance of these improvements and the optimal structure of specialized pain clinics.

[Orthopedic aspects in interdisciplinary multimodal therapy of chronic back pain]

The effect of interdisciplinary multimodal therapy of chronic back pain is well documented. With elapsing time changing diagnostic focuses, therapeutic strategies and objectives have to be considered. The chronicity leads to a modification of the relevance of structure-related diagnosis and therapy and changes the significance of the classic orthopedic instruments. The requirement of a rational causal therapy in chronic back pain still remains but the focal points shift to the consideration of somatic, psychological and social disposing and supporting factors.The aim of this paper is to reflect the necessary orthopedic expertise in the context of the pathomechanics of chronic back pain and the interdisciplinary teamwork.

A bio-psycho-social exercise program (RÜCKGEWINN) for chronic low back pain in rehabilitation aftercare--study protocol for a randomised controlled trial

Background

There is strong, internationally confirmed evidence for the short-term effectiveness of multimodal interdisciplinary specific treatment programs for chronic back pain. However, the verification of long-term sustainability of achieved effects is missing so far. For long-term improvement of pain and functional ability high intervention intensity or high volume seems to be necessary (> 100 therapy hours). Especially in chronic back pain rehabilitation, purposefully refined aftercare treatments offer the possibility to intensify positive effects or to increase their sustainability. However, quality assured goal-conscious specific aftercare programs for the rehabilitation of chronic back pain are absent.

Methods/Design

This study aims to examine the efficacy of a specially developed bio-psycho-social chronic back pain specific aftercare intervention (RÜCKGEWINN) in comparison to the current usual aftercare (IRENA) and a control group that is given an educational booklet addressing pain-conditioned functional ability and back pain episodes. Overall rehabilitation effects as well as predictors for compliance to the aftercare programs are analysed. Therefore, a multicenter prospective 3-armed randomised controlled trial is conducted. 456 participants will be consecutively enrolled in inpatient and outpatient rehabilitation and assigned to either one of the three study arms. Outcomes are measured before and after rehabilitation. Aftercare programs are assessed at ten month follow up after dismissal form rehabilitation.

Discussion

Special methodological and logistic challenges are to be mastered in this trial, which accrue from the interconnection of aftercare interventions to their residential district and the fact that the proportion of patients who take part in aftercare programs is low. The usability of the aftercare program is based on the transference into the routine care and is also reinforced by developed manuals with structured contents, media and material for organisation assistance as well as training manuals for therapists in the aftercare.

Adaptive leadership and the practice of medicine: a complexity-based approach to reframing the doctor-patient relationship

RATIONALE, AIMS AND OBJECTIVES

This paper applies the concepts of 'adaptive leadership', as developed by Ron Heifetz, MD, to the practice of medicine.

METHODS

Literature review and theory development.

RESULTS

Patients are complex adaptive systems facing both adaptive and technical health challenges. Technical health challenges are amenable to the simple or complicated expert-mediated technical interventions that are common in modern medicine, but complex adaptive challenges can only be addressed by patients doing the adaptive work to learn new attitudes, beliefs and behaviours. In medicine, we often make the mistake of offering technical interventions in lieu of supporting patients' adaptive work. This error can result in poor clinical outcomes and wasted resources. Expecting simple or complicated technical 'solutions' to resolve complex adaptive health challenges is a failure of adaptive leadership and violates Ashby's law of requisite variety. Adaptive leadership behaviours correspond to and complement doctor practices that have been shown to improve health outcomes and doctor-patient communication.

CONCLUSIONS

Adopting an adaptive leadership framework in the practice of medicine will require adaptive work on our part, but it promises to improve the doctor-patient relationship, increase our effectiveness as healers and reduce unnecessary health care utilization.

Daily functioning and self-management in patients with chronic low back pain after an intensive cognitive behavioral programme for pain management

Chronic low back pain (CLBP) is associated with persistent or recurrent disability which results in high costs for society. Cognitive behavioral treatments produce clinically relevant benefits for patients with CLBP. Nevertheless, no clear evidence for the most appropriate intervention is yet available. The purpose of this study is to evaluate the mid-term effects of treatment in a cohort of patients with CLBP participating in an intensive pain management programme. The programme provided by RealHealth-Netherlands is based on cognitive behavioral principles and executed in collaboration with orthopedic surgeons. Main outcome parameters were daily functioning (Roland and Morris Disability Questionnaire and Oswestry Disability Questionnaire), self-efficacy (Pain Self-Efficacy Questionnaire) and quality of life (Short Form 36 Physical Component Score). All parameters were measured at baseline, last day of residential programme and at 1 and 12 months follow-up. Repeated measures analysis was applied to examine changes over time. Clinical relevance was examined using minimal clinical important differences (MCID) estimates for main outcomes. To compare results with literature effect sizes (Cohen’s d) and Standardized Morbidity Ratios (SMR) were determined. 107 patients with CLBP participated in this programme. Mean scores on outcome measures showed a similar pattern: improvement after residential programme and maintenance of results over time. Effect sizes were 0.9 for functioning, 0.8 for self-efficacy and 1.3 for physical functioning related quality of life. Clinical relevancy: 79% reached MCID on functioning, 53% on self-efficacy and 80% on quality of life. Study results on functioning were found to be 36% better and 2% worse when related to previous research on, respectively, rehabilitation programmes and spinal surgery for similar conditions (SMR 136 and 98%, respectively). The participants of this evidence-based programme learned to manage CLBP, improved in daily functioning and quality of life. The study results are meaningful and comparable with results of spinal surgery and even better than results from less intensive rehabilitation programmes.

[Interdisciplinary treatment. Long-lasting, effective, and cost-effective]

The efficacy of intensive interdisciplinary pain management programs for patients with chronic low back pain has been repeatedly demonstrated. A controversial issue in previous studies is the cost-effectiveness of this treatment. Between 2001 and 2006, a total of 575 patients with chronic nonspecific back pain took part in an outpatient pain management program at the German Red Cross Pain Center (DRK Schmerz-Zentrum Mainz) in Mainz, Germany. Complete follow-up data were available for 351 patients 1 year after the end of treatment and were included in the study. No differences between these patients and the dropouts were found. Pain, impairment, and mental well-being had significantly improved after 1 year. For employed patients, the number of absent days decreased to almost one-quarter. On the basis of the study by Wenig, who calculated pain-related costs as a function of Von Korff pain grades, the treatment resulted in a savings of euro 3,329.50 per year per patient. Intensive multidisciplinary treatment of chronic back pain is highly effective and, at least for patients with high levels of disability, is also cost-effective.

Barriers to treatment adherence in physiotherapy outpatient clinics: a systematic review

Poor adherence to treatment can have negative effects on outcomes and healthcare cost. However, little is known about the barriers to treatment adherence within physiotherapy. The aim of this systematic review was to identify barriers to treatment adherence in patients typically managed in musculoskeletal physiotherapy outpatient settings and suggest strategies for reducing their impact. The review included twenty high quality studies investigating barriers to treatment adherence in musculoskeletal populations. There was strong evidence that poor treatment adherence was associated with low levels of physical activity at baseline or in previous weeks, low in-treatment adherence with exercise, low self-efficacy, depression, anxiety, helplessness, poor social support/activity, greater perceived number of barriers to exercise and increased pain levels during exercise. Strategies to overcome these barriers and improve adherence are considered. We found limited evidence for many factors and further high quality research is required to investigate the predictive validity of these potential barriers. Much of the available research has focussed on patient factors and additional research is required to investigate the barriers introduced by health professionals or health organisations, since these factors are also likely to influence patient adherence with treatment.

Physical conditioning programs for improving work outcomes in workers with back pain

BACKGROUND

Physical conditioning programs aim to improve work status for workers on sick leave. This is an update of a Cochrane Review (Work conditioning, work hardening and functional restoration for workers with back and neck pain) first published in 2003.

OBJECTIVES

To compare the effectiveness of physical conditioning programs in reducing time lost from work for workers with back pain.

SEARCH STRATEGY

We searched the following databases to June/July 2008: CENTRAL (The Cochrane Library 2008, issue 3), MEDLINE from 1966, EMBASE from 1980, CINAHL from 1982, PsycINFO from 1967, and PEDro.

SELECTION CRITERIA

Randomized controlled trials (RCTs) and cluster RCTs that studied workers with work disability related to back pain and who were included in physical conditioning programs.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias.

MAIN RESULTS

Thirty-seven references, reporting on 23 RCTs (3676 workers) were included, 13 of which had a low risk of bias. In 14 studies, physical conditioning programs were compared to usual care. In workers with acute back pain, there was no effect on sickness absence. For workers with subacute back pain, we found conflicting results, but subgroup analysis showed a positive effect of interventions with workplace involvement. In workers with chronic back pain, pooled results of five studies showed a small effect on sickness absence at long-term follow-up (SMD: -0.18 (95% CI: -0.37 to 0.00)). In workers with chronic back pain, physical conditioning programs were compared to other exercise therapy in six studies, with conflicting results. The addition of cognitive behavioural therapy to physical conditioning programs was not more effective than the physical conditioning alone.

AUTHORS' CONCLUSIONS

The effectiveness of physical conditioning programs in reducing sick leave when compared to usual care or than other exercises in workers with back pain remains uncertain. In workers with acute back pain, these programs probably have no effect on sick leave, but there may be a positive effect on sick leave for workers with subacute and chronic back pain. Workplace involvement might improve the outcome. Better understanding of the mechanism behind physical conditioning programs and return-to-work is needed to be able to develop more effective interventions.

[The Dachau multidisciplinary treatment program for chronic pain. Efficacy data of a diagnosis-independent multidisciplinary treatment program for back pain and other types of chronic pain]

BACKGROUND

Data on the efficacy of the Dachau multidisciplinary treatment program for chronic pain is presented. The treatment is administered in a primary care day clinic and the treatment period is 5 weeks plus 5 booster days 6 months later. The program is characterized by high treatment intensity (122.5 h over 5 weeks) and is aimed at patients where outpatient pain therapy proved to be insufficient. The treatment plan is applicable to different types of chronic pain and the main treatment objective is functional restoration.

METHODS

Outcome criteria were pain intensity, disability, vitality, depression, catastrophizing, and employment status. The data was assessed at the beginning of treatment, after 5 weeks and 6 months after therapy. The patient population consisted of 189 chronic pain patients.

RESULTS

All outcome criteria showed a significant and stable improvement over 6 months. Effect sizes demonstrated medium and high treatment effects. The back to work rate was 63% at 6 months follow-up.

DISCUSSION

The Dachau multidisciplinary treatment for chronic pain achieved significant improvements which remained stable for 6 months after treatment.

[Multimodal pain therapy: principles and indications]

Multimodal pain therapy describes an integrated multidisciplinary treatment in small groups with a closely coordinated therapeutical approach. Somatic and psychotherapeutic procedures cooperate with physical and psychological training programs. For chronic pain syndromes with complex somatic, psychological and social consequences, a therapeutic intensity of at least 100 hours is recommended. Under these conditions multimodal pain therapy has proven to be more effective than other kinds of treatment. If monodisciplinary and/or outpatient therapies fail, health insurance holders have a legitimate claim to this form of therapy.Medical indications are given for patients with chronic pain syndromes, but also if there is an elevated risk of chronic pain in the early stadium of the disease and aiming at delaying the process of chronification. Relative contraindications are a lack of motivation for behavioural change, severe mental disorders or psychopathologies and addiction problems. The availability of multimodal pain treatment centers in Germany is currently insufficient.

Chronic low back pain: Patients' experiences, opinions and expectations for clinical management

PURPOSE

To explore the experiences, opinions and treatment expectations of chronic low back pain (LBP) patients in order to identify what components of treatment they consider as being of most value.

METHOD

Three stand-alone focus groups were convened. All participants were experiencing chronic non-specific LBP (>3 months). Each group was facilitated by an independent moderator, and guided by a series of pre-determined questions. Participants were encouraged to freely air their personal opinions during the discussion. Transcribed data were organized into a series of 'categories' using the Qualitative Solutions for Researchers Nudist 6 package from which five common themes emerged.

RESULTS

Each participant had typically experienced a variety of failed treatment approaches. Whilst the value of advice and exercise was recognized, participants typically questioned the appropriateness of such treatment given the fact that a precise diagnosis was rarely given, and symptoms often recurred. As a result, poor adherence with advice and exercise appeared to be a key factor limiting the potential effectiveness of long-term self-management strategies.

CONCLUSIONS

Participants considered appropriate exercise (despite pain) and activity modification as important components for effective long-term self-management of symptoms. To enhance treatment effectiveness, participants welcomed the introduction of individually tailored advice and exercise programmes, with supervision and follow-up support, along with a better understanding of the physical and emotional impact of chronic LBP by practitioners.

Land-based versus pool-based exercise for people awaiting joint replacement surgery of the hip or knee: results of a randomized controlled trial

OBJECTIVE

To compare the preoperative effects of multidimensional land-based and pool-based exercise programs for people awaiting joint replacement surgery of the hip or knee.

DESIGN

Randomized, single-blind, before-after trial.

SETTING

Physiotherapy gymnasium and hydrotherapy pool.

PARTICIPANTS

Patients awaiting elective hip or knee joint replacement surgery.

INTERVENTIONS

Land-based (n=40) or pool-based exercise program (n=42). Each 6-week program included an education session, twice-weekly exercise classes, and an occupational therapy home assessment.

MAIN OUTCOME MEASURES

Participants were assessed immediately before and after the 6-week intervention, then 8 weeks later. Primary outcomes were pain and self-reported function (Western Ontario and McMaster Universities Osteoarthritis Index) and patient global assessment. Secondary outcomes were performance-based measures (timed walk and chair stand) and psychosocial status (Medical Outcomes Study 36-Item Short-Form Health Survey mental component score). Pain was also measured before and after each exercise class on a 7-point verbal rating scale.

RESULTS

Although both interventions were effective in reducing pain and improving function, there were no postintervention differences between the groups for the primary and secondary outcomes. However, the pool-based group had less pain immediately after the exercise classes.

CONCLUSIONS

While our multidimensional exercise-based interventions appeared to be effective in reducing disability in those awaiting joint replacement surgery of the hip or knee, there were no large differences in the postintervention effects of the interventions. However, pool-based exercise appeared to have a more favorable effect on pain immediately after the exercise classes.

Value of functional capacity evaluation information in a clinical setting for predicting return to work

OBJECTIVE

To evaluate the quality of Functional Capacity Evaluation (FCE) information in predicting return to work (RTW).

DESIGN

Prospective cohort study.

SETTING

Inpatient rehabilitation clinic.

PARTICIPANTS

Patients (N=220) with chronic musculoskeletal disorders (MSD) conducting a medical rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Patients filled in questionnaires at admission and 1-year follow-up. An FCE was performed on admission. RTW was defined as a combination of employment at 1-year follow-up with a maximum of 6 weeks sick leave because of MSD in the postrehabilitation year. As predictive FCE information, the physical capacity (Dictionary of Occupational Titles categories 1-5), the number of test results not meeting work demands (0-25), and the tester's recommendation of work ability in the actual job (> or =6h/d) were analyzed. Logistic regression models (crude and adjusted for the concurrent predictors employment, preadmission sick leave, and patient's prognosis of RTW) were created to predict RTW.

RESULTS

Complete data were obtained for 145 patients. The sample showed a non-RTW at 1-year follow-up for 37.9%. All FCE information showed significant relations to RTW (r=.28-.43; P<.05). In the crude as well as in the adjusted regression models, all FCE information predicted RTW, but the models' quality was low. The integration of FCE information led to an increase of 5%. The predictive efficiency was poor. The adjusted model for failed tests showed a substantial improvement compared with the reference model (concurrent predictors only).

CONCLUSIONS

There was a significant relation between FCE information and RTW with and without concurrent predictors, but the predictive efficiency is poor. Primarily, the number of failed tests seemed to be of significance for patients with ambiguous RTW prognosis. A first proposal for a prediction rule was discussed.

Need for rehabilitation teamwork training in Europe

Teamwork is the cornerstone of rehabilitation medicine. Rehabilitation workers in European countries are well educated in their own disciplines and attain appropriate professional knowledge; however, they lack educational opportunities for acquiring skills and attitudes necessary for effective teamwork, mainly communication, cooperation, and leadership. Consequently, teamwork is compromised and rehabilitation effectiveness reduced. Therefore, training in these components of professional competence needs scaling up in order to increase their impact on rehabilitation care.

An interdisciplinary clinical practice model for the management of low-back pain in primary care: the CLIP project

BACKGROUND

Low-back pain is responsible for significant disability and costs in industrialized countries. Only a minority of subjects suffering from low-back pain will develop persistent disability. However, this minority is responsible for the majority of costs and has the poorest health outcomes. The objective of the Clinic on Low-back pain in Interdisciplinary Practice (CLIP) project was to develop a primary care interdisciplinary practice model for the clinical management of low-back pain and the prevention of persistent disability.

METHODS

Using previously published guidelines, systematic reviews and meta-analyses, a clinical management model for low-back pain was developed by the project team. A structured process facilitating discussions on this model among researchers, stakeholders and clinicians was created. The model was revised following these exchanges, without deviating from the evidence.

RESULTS

A model consisting of nine elements on clinical management of low-back pain and prevention of persistent disability was developed. The model's two core elements for the prevention of persistent disability are the following: 1) the evaluation of the prognosis at the fourth week of disability, and of key modifiable barriers to return to usual activities if the prognosis is unfavourable; 2) the evaluation of the patient's perceived disability every four weeks, with the evaluation and management of barriers to return to usual activities if perceived disability has not sufficiently improved.

CONCLUSION

A primary care interdisciplinary model aimed at improving quality and continuity of care for patients with low-back pain was developed. The effectiveness, efficiency and applicability of the CLIP model in preventing persistent disability in patients suffering from low-back pain should be assessed.

Chronic pain in persons with myotonic dystrophy and facioscapulohumeral dystrophy

OBJECTIVE

To determine the nature and scope of pain in working-aged adults with myotonic muscular dystrophy (MMD) and facioscapulohumeral muscular dystrophy (FSHD).

DESIGN

Retrospective, cross-sectional survey.

SETTING

Community-based survey.

PARTICIPANTS

Convenience sample of subjects with MMD and FSHD.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Overall intensity and duration of pain, pain inference, pain sites, pain treatments, and relief provided by pain treatments.

RESULTS

More subjects with FSHD (82%) than with MMD (64%) reported pain. The most frequently reported pain sites for both diagnostic groups were lower back (66% MMD, 74% FSHD) and legs (60% MMD, 72% FSHD). Significant differences in pain intensity were found between the diagnostic groups in the hands, legs, knees, ankles, and feet, with patients with MMD reporting greater pain intensity at these sites than patients with FSHD. Age was related to the onset of pain (participants reporting pain were younger than those not reporting pain in the FSHD sample), but pain severity was not significantly associated with age in those reporting pain. Respondents with both diagnoses that reported mobility limitations and used assistive devices (eg, wheelchair, cane) reported more pain severity than those with mobility limitations who did not use assistive devices, who, in turn, reported more pain severity than respondents who reported no mobility limitations at all. The treatments that were reported to provide the greatest pain relief were not necessarily those that were the most frequently tried or still used.

CONCLUSIONS

The findings indicate that pain is a more common problem in persons with FSHD than in persons with MMD, although it is common in both populations. In addition, these pain problems are chronic, underscoring the need to identify and provide effective pain treatments for patients with these neuromuscular diseases.

The impact of aerobic fitness on functioning in chronic back pain

Despite lack of convincing evidence that reduced aerobic fitness is associated with chronic back pain (CBP), exercise programs are regarded as being effective for persons with non-specific CBP. It is unsure whether gain in aerobic fitness following intervention is associated with functioning improvement in persons with CBP. The objective of this prospective cohort study was to study the impact of aerobic fitness on functioning in persons with CBP, at baseline and following 3-week intensive interdisciplinary intervention. This study included persons who had passed 8 weeks of sick-listing because of back pain (n = 94) and were referred to a 3-week intensive biopsychosocial rehabilitation program. Aerobic fitness was assessed with a sub-maximal bicycle test at baseline, at admission to and discharge from the rehabilitation program, and at 6 months follow-up. Contextual factors, body function, activity and participation were evaluated before and after intervention. In addition, working ability was recorded at 3-years follow-up. At baseline aerobic fitness was reduced in most subjects, but improved significantly following intervention. Baseline measurements and intervention effects did not differ among the diagnostic sub-groups. Neither contextual factors nor functioning at baseline were associated with aerobic fitness. Increase in aerobic fitness was not associated with improvements in functioning and contextual factors and work-return following intervention either. From this study we conclude that improvement of aerobic fitness seems of limited value as goal of treatment outcome for patients with CBP.

[Pain clinics within Austrian hospitals, for patients with pathologies of the locomotor system. Analysis of care and comparison with Germany]

This paper gives a comparative overview of the current clinical care of patients experiencing pain in the musculoskeletal system in Austria and in Germany. The questionnaire used in this study was modified from one used in a survey carried out in Germany in 2002. In our version we asked specifically about pain in the musculoskeletal system. In all 228 health care facilities were reviewed, 56.6% of which offer at least one option for pain therapy. In Austria, the majority of patients with pain in the musculoskeletal system are treated by specialists in the departments of anaesthesiology, internal medicine, and orthopaedics. In 17.4% of the clinics in Austria there are plans to extend the pain therapy they offer, but in over half of the hospitals that responded facilities for pain therapy are considered to be vulnerable. The study highlights a significant higher percentage of in-patient pain therapy services in Austria, while in Germany, in contrast, there are more outpatient options for pain therapy. The quality of pain therapy could by further improved by more intense cooperation between the inpatient and outpatient sectors and by the establishment of interdisciplinary and multimodal solutions.

Effect sizes of non-surgical treatments of non-specific low-back pain

Numerous randomized trials have been published investigating the effectiveness of treatments for non-specific low-back pain (LBP) either by trials comparing interventions with a no-treatment group or comparing different interventions. In trials comparing two interventions, often no differences are found and it raises questions about the basic benefit of each treatment. To estimate the effect sizes of treatments for non-specific LBP compared to no-treatment comparison groups, we searched for randomized controlled trials from systematic reviews of treatment of non-specific LBP in the latest issue of the Cochrane Library, issue 2, 2005 and available databases until December 2005. Extracted data were effect sizes estimated as Standardized Mean Differences (SMD) and Relative Risk (RR) or data enabling calculation of effect sizes. For acute LBP, the effect size of non-steroidal anti-inflammatory drugs (NSAIDs) and manipulation were only modest (ES: 0.51 and 0.40, respectively) and there was no effect of exercise (ES: 0.07). For chronic LBP, acupuncture, behavioral therapy, exercise therapy, and NSAIDs had the largest effect sizes (SMD: 0.61, 0.57, and 0.52, and RR: 0.61, respectively), all with only a modest effect. Transcutaneous electric nerve stimulation and manipulation had small effect sizes (SMD: 0.22 and 0.35, respectively). As a conclusion, the effect of treatments for LBP is only small to moderate. Therefore, there is a dire need for developing more effective interventions.

Exploring the contribution of patient-reported and clinician based variables for the prediction of low back work status

BACKGROUND

Successful management of workers on sick leave due to low back pain by the general physician and physiotherapist depends on reliable prognostic information on the course of low back pain and work resumption.

METHODS

Retrospective cohort study in 194 patients who were compensated because of chronic low back pain and who were treated by a physiotherapy functional restoration program. Patient-reported and clinician based prognostic indicators were assessed at baseline before patients entered the functional restoration program. We investigated the predictive value of these indicators on work status at 6 months. Relationships were studied using logistic regression analysis in a 2-step bootstrap modelling approach and a nomogram was developed. Discrimination and calibration of the nomogram was evaluated internally and the explained variation of the nomogram calculated.

RESULTS

Seventy percent of workers were back to work at 6 months. We found that including duration of complaints, functional disability, disc herniation and fear avoidance beliefs resulted in the "best" prognostic model. All these factors delayed work resumption. This model was used to construct a nomogram. The explained variation of the nomogram was 23.7%. Discrimination was estimated by the area under the receiver operating characteristic curve and was 0.76 and for calibration we used the slope estimate that was 0.91. The positive predictive values of the nomogram at different cut-off levels of predicted probability were good.

CONCLUSIONS

Knowledge of the predictive value of these indicators by physicians and physiotherapists will help to identify subgroups of patients and will thus enhance clinical decision-making.

Qualitative evaluation of the expectations of low back pain patients with regard to information gained through semi-directed navigation on the Internet

OBJECTIVES

To make a qualitative analysis of the expectations of chronic low back pain (LBP) sufferers with regard to information gained using semi-directed Internet navigation on a sample of French LBP-related websites, and to compare the results with those of physical medicine and rehabilitation (PMR) medical doctors (MD).

MATERIAL AND METHODS

Twenty-seven hospitalised chronic LBP sufferers assessed in ecological conditions a sample of seven LBP-related websites. The sites were assessed using a simplified version of a rating scale of patients' expectations. Analysis of the relative importance of the different kinds of information delivered was done using a point sharing method.

RESULTS

In a comfortable environment, patients gave high scores for medical and extra-medical information, but low scores for website design. Overall quality assessment was similar for patients and MDs. The relative importance of medical and extra-medical information, and design quality, was similar for Chronic LBP patients and MDs.

CONCLUSION

PMR MD seemed able to correctly evaluate the overall expectations of chronic LBP patients with regard to information, but their opinions on the different qualities of websites were different. Doctors and patients should collaborate in order to create or validate high quality websites concerned with LBP.

Physical disability due to musculoskeletal conditions

Musculoskeletal conditions (MSC) are common throughout the world and their impact on individuals is diverse and manifold. Knowledge of the determinants for disability and of strategies for prevention and rehabilitation management according to the scientific evidence is critical for reducing the burden of MSC. The first section of this chapter reviews the evidence for common determinants of functioning and disability in patients with MSC. We have focussed on environmental factors (EF) and personal factors (PF) and have structured them according to the International Classification of Functioning, Disability and Health (ICF) framework. The second section discusses prevention strategies. Generally, prevention needs to address those EF and PF that were presented in the first section. The final section describes modern principles of rehabilitation and reviews the evidence for specific rehabilitation interventions.

Social learning contributions to the etiology and treatment of functional abdominal pain and inflammatory bowel disease in children and adults

This paper reviews empirical work on cognitive and social learning contributions to the etiology and treatment of illness behavior associated with functional abdominal pain and inflammatory bowel disease. A particular emphasis is placed on randomized controlled trials, the majority of which are multi-modal in orientation, incorporating elements of cognitive behavioral therapy, social learning, and relaxation. Based on this review, we offer methodological and clinical suggestions: (1) Research investigations should include adequate sample sizes, long-term follow-up assessments, and a credible, active control group. (2) Standard gastrointestinal practice should include, when appropriate, learning opportunities for patients and family members, for example, instruction regarding the encouragement of wellness behavior.

Management of functional somatic syndromes

Although functional somatic syndromes (FSS) show substantial overlap, treatment research is mostly confined to single syndromes, with a lack of valid and generally accepted diagnostic criteria across medical specialties. Here, we review management for the full variety of FSS, drawn from systematic reviews and meta-analyses since 2001, and give recommendations for a stepped care approach that differentiates between uncomplicated and complicated FSS. Non-pharmacological treatments involving active participation of patients, such as exercise and psychotherapy, seem to be more effective than those that involve passive physical measures, including injections and operations. Pharmacological agents with CNS action seem to be more consistently effective than drugs aiming at restoration of peripheral physiological dysfunction. A balance between biomedical, organ-oriented, and cognitive interpersonal approaches is most appropriate at this truly psychosomatic interface. In view of the iatrogenic component in the maintenance of FSS, doctor-centred interventions and close observation of the doctor-patient relationship are of particular importance.

Segmental lumbar mobility in individuals with low back pain: in vivo assessment during manual and self-imposed motion using dynamic MRI

Background

Altered spinal mobility is thought to be related to current or past episodes of low back pain; however evidence of that relationship in younger subjects has not been established. The purpose of this study was to compare lumbar segmental mobility in asymptomatic and symptomatic subjects during posterior to anterior (PA) manual spinal mobilization and a self-initiated prone press-up (PU) maneuver. We hypothesized that persons with central low back pain would have an altered lumbar segmental mobility pattern compared to those without pain.

Method

Forty-five individuals (age 32.1 ± 8.5) with non-specific low back pain and 20 persons (age 31.1 ± 7.0) without low back pain participated. Each subject underwent dynamic imaging of the lumbar spine during a PA mobilization procedure and while performing a PU. Segmental motion was quantified as the change in the intervertebral angle between the resting and end-range vertebral positions.

Results

The symptomatic group had a larger percentage of subjects with evidence of single level segmental hypermobility than the asymptomatic group during the PA (40.0% vs. 5%) and PU (26.7% vs. 15%) procedures. Single lumbar motion-segment analysis revealed hyper-mobility in symptomatic subjects at L5 – S1 (Chi-square = 10.0, p ≤ 0.01) and L4 – L5 (Chi-square = 4.18, p ≤ 0.05) during the PA test.

Conclusion

Persons with non-specific low back pain have a tendency to demonstrate single level lumbar segmental hypermobility when compared to age specific asymptomatic subjects.
