Assessing the role of cognitive behavioral therapy in the management of chronic nonspecific back pain

Psychophysiologic symptom relief therapy for chronic back pain: hypothesis and trial rationale

Chronic pain syndromes affect over one-third of the US adult population and often lead to significant disability and a reduced quality of life. Despite their high prevalence, causal links between chronic pain syndromes and anatomic abnormalities are often not apparent. Most current chronic pain treatments provide modest, if any, relief. Thus, there is a pressing need to understand the causal mechanisms implicated in chronic pain as a means to develop more targeted interventions for improvement in clinical outcomes and reduction in morbidity and financial burden. In the present manuscript, we summarize the current literature on treatment for chronic pain, and hypothesize that non-specific chronic back pain (without a clear organic etiology, such as tumors, infections or fractures) is of psychophysiologic origin. Based on this hypothesis, we developed Psychophysiologic Symptom Relief Therapy (PSRT), a novel pain reduction intervention for understanding and treating chronic pain. In this manuscript, we provide the rationale for PSRT, which we have tested in a pilot trial with a subsequent larger randomized trial underway. In the proposed trial, we will evaluate whether non-specific chronic back pain can be treated by addressing the underlying stressors and psychological underpinnings without specific physical interventions.

Effect of multidimensional physiotherapy on non-specific chronic low back pain: a randomized controlled trial

BACKGROUND

Many people with non-specific chronic low back pain (NSCLBP) do not recover with current conventional management. Systematic reviews show multidimensional treatment improves pain better than usual active interventions. It is unclear whether multidimensional physiotherapy improves pain better than usual physiotherapy. This study determines the effectiveness of this treatment to reduce pain and disability and improve quality of life, pain cognitions, and electroencephalographic pattern in individuals with NSCLBP.

METHODS

70 eligible participants aged 18 to 50 years with NSCLBP were randomized into either the experimental group (multidimensional physiotherapy) or the active control group (usual physiotherapy). Pain intensity was measured as the primary outcome. Disability, quality of life, pain Catastrophizing, kinesiophobia, fear Avoidance Beliefs, active lumbar range of motion, and brain function were measured as secondary outcomes. The outcomes were measured at pre-treatment, post-treatment, 10, and 22 weeks. Data were analyzed using intention-to-treat approaches.

RESULTS

There were 17 men and 18 women in the experimental group (mean [SD] age, 34.57 [6.98] years) and 18 men and 17 women in the active control group (mean [SD] age, 35.94 [7.51] years). Multidimensional physiotherapy was not more effective than usual physiotherapy at reducing pain intensity at the end of treatment. At the 10 weeks and 22 weeks follow-up, there were statistically significant differences between multidimensional physiotherapy and usual physiotherapy (mean difference at 10 weeks, -1.54; 95% CI, -2.59 to -0.49 and mean difference at 22 weeks, -2.20; 95% CI, - 3.25 to - 1.15). The standardized mean difference and their 95% confidence intervals (Cohen's d) revealed a large effect of pain at 22 weeks: (Cohen's d, -0.89; 95% CI (-1.38 to-0.39)). There were no statistically significant differences in secondary outcomes.

CONCLUSIONS

In this randomized controlled trial, multidimensional physiotherapy resulted in statistically and clinically significant improvements in pain compared to usual physiotherapy in individuals with NSCLBP at 10 and 22 weeks.

The cognitive-behavioral aspects of the Mulligan concept of manual therapy: A systematic review

Low back pain (LBP) is a common clinical problem imposing a prominent socio-economic burden. The purpose of this systematic review was to investigate the biopsychosocial effects of the Mulligan Concept (MC) of manual therapy (MT) when applied to patient's with LBP. Three researchers independently evaluated the literature quality, and completed a review on five online databases (Medline, Cochrane Library, Science Direct, ProQuest and Google Scholar) for articles published from January 1st 2010 to November 20th 2021, using a combination of free words, Wildcards and Medical Subject Headings (MESH) terms: " Mulligan mobilization " AND " back pain " OR " SNAGs." In total, 62 studies were selected for full-text reading, from which finally 6 studies were included in the present review. The results revealed that the studies where the MC of MT was applied to treat LBP mainly lacked concern regarding the effect that the intervention has on the cognitive and behavioural parameters. The ones that introduced measure outcomes for at least some parts of the cognitive behavioural components, showed that the MC has a positive effect, even though without a long-term follow-up assessment. This review summarized that the evidence of the MC on cognitive behavioural (CB) aspects of patients with LBP is controversial and scarce.

Digital self-management interventions for osteoarthritis: a systematic scoping review of intervention characteristics, adherence and attrition

Background

Osteoarthritis (OA) is a chronic, progressive condition that can be effectively managed via conservative treatments including exercise, weight management and education. Offering these treatments contemporaneously and digitally may increase adherence and engagement due to the flexibility and cost-effectiveness of digital program delivery. The objective of this review was to summarise the characteristics of current digital self-management interventions for individuals with OA and synthesise adherence and attrition outcomes.

Methods

Electronic databases were searched for randomised controlled trials utilising digital self-management interventions in individuals with OA. Two reviewers independently screened the search results and extracted data relating to study characteristics, intervention characteristics, and adherence and dropout rates.

Results

Eleven studies were included in this review. Intervention length ranged from 6 weeks to 9 months. All interventions were designed for individuals with OA and mostwere multi-component and were constructed around physical activity. The reporting of intervention adherence varied greatly between studies and limited the ability to form conclusions regarding the impact of intervention characteristics. However, of the seven studies that quantified adherence, six reported adherence > 70%. Seven of the included studies reported attrition rates < 20%, with contact and support from researchers not appearing to influence adherence or attrition.

Conclusions

Holistic digital interventions designed for a targeted condition are a promising approach for promoting high adherence and reducing attrition. Future studies should explore how adherence of digital interventions compares to face-to-face interventions and determine potential influencers of adherence.

Breaking the vicious circle: Experiences of people in chronic pain on the pain rehabilitation journey

Aim

To explore the lived experience of individuals' in chronic pain of participating in a pain rehabilitation programme in Iceland.

Design

Phenomenological research.

Method

The Vancouver School of Doing Phenomenology. Eleven participants were interviewed.

Results

The overarching theme was as follows: "the journey of breaking the vicious circle of chronic pain." Before the programme, the participants felt they were in survival mode, trying to survive each day; they were stuck in a vicious circle of chronic pain, simultaneously trying to ease and conceal the pain. Reaching out for professional help was a turning point. While attending the programme, participants began deconstructing their old ways of dealing with chronic pain. After completing the programme, they were still reconstructing their daily lives. In conclusion, pain rehabilitation programmes can be the first step towards breaking the vicious circle of chronic pain.

The effect of pain management group on chronic pain and pain related co-morbidities and symptoms. A stepped-wedge cluster randomized controlled trial. A study protocol

INTRODUCTION

In primary care settings, pain-management group therapy is a tool potentially cost-effective but very much underused.

METHODS

Our purpose here is to provide useful scientific information on the effect of pain-management group participation on chronic pain and pain-related co-morbidities and symptoms, as well as practical information for primary and occupational health services to initiate pain-management group activity.This study will be carried out at primary care Occupational Health Helsinki (Helsinki city employees' occupational health services), with the Finnish Institute of Occupational Health as the research partner.This is a stepped-wedge cluster randomized controlled trial among both male and female municipal employees aged 18 to 65, all of whom had visited an occupational doctor, nurse, psychologist, or physiotherapist because of any chronic pain unrelated to malignant disease. An additional inclusion criterion is work disability risk being elevated, based on a short screening questionnaire (modified Örebro questionnaire). Each participant and each interviewer will be blinded at randomization. Three groups, 10 subjects in each, begin directly after recruitment with 6 weekly 2-h meetings and a follow-up meeting 6 months later. Three waiting-list groups begin 4 months later. Subjects complete self-administered questionnaires before and after the sixth meetings, also 6 months later. Primary outcomes are pain intensity, current work ability, pain self-efficacy, fear-avoidance beliefs, chronic pain acceptance, depressive symptoms, sleep problems, sickness absence days, and number of occupational health care contacts from OH's medical records.

RESULTS

We will publish our results in a peer-reviewed scientific journals.

Healthy Lifestyle Program (HeLP) for low back pain: protocol for a randomised controlled trial

INTRODUCTION

Low back pain is one of the most common and burdensome chronic conditions worldwide. Lifestyle factors, such as excess weight, physical inactivity, poor diet and smoking, are linked to low back pain chronicity and disability. There are few high-quality randomised controlled trials that investigate the effects of targeting lifestyle risk factors in people with chronic low back pain.

METHODS AND ANALYSIS

The aim of this study is to determine the effectiveness of a Healthy Lifestyle Program (HeLP) for low back pain targeting weight, physical activity, diet and smoking to reduce disability in patients with chronic low back pain compared with usual care. This is a randomised controlled trial, with participants stratified by body mass index, allocated 1:1 to the HeLP intervention or usual physiotherapy care. HeLP involves three main components: (1) clinical consultations with a physiotherapist and dietitian; (2) educational resources; and (3) telephone-based health coaching support for lifestyle risk factors. The primary outcome is disability (Roland Morris Disability Questionnaire) at 26 weeks. Secondary outcomes include pain intensity, weight, quality of life and smoking status. Data will be collected at baseline, and at weeks 6, 12, 26 and 52. Patients with chronic low back pain who have at least one health risk factor (are overweight or obese, are smokers and have inadequate physical activity or fruit and vegetable consumption) will be recruited from primary or secondary care, or the community. Primary outcome data will be analysed by intention to treat using linear mixed-effects regression models. We will conduct three supplementary analyses: causal mediation analysis, complier average causal effects analysis and economic analysis.

ETHICS AND DISSEMINATION

This study was approved by the Hunter New England Research Ethics Committee (Approval No 17/02/15/4.05), and the University of Newcastle Human Research Ethics Committee (Ref No H-2017-0222). Outcomes of this trial and supplementary analyses will be disseminated through publications in peer-reviewed journals and conference presentations.

Effects of a Home-Based Telephone-Supported Physical Activity Program for Older Adult Veterans With Chronic Low Back Pain

BACKGROUND

Chronic low back pain (CLBP) is highly prevalent in older adults, leading to functional decline.

OBJECTIVE

The objective of this study was to evaluate physical activity (PA) only and PA plus cognitive-behavioral therapy for pain (CBT-P) among older adult veterans with CLBP.

DESIGN

This study was a pilot randomized trial comparing a 12-week telephone-supported PA-only intervention group (PA group) or PA plus CBT-P intervention group (PA + CBT-P group) and a wait-list control group (WL group).

SETTING

The study setting was the Durham Veterans Affairs Health Care System.

PARTICIPANTS

The study participants were 60 older adults with CLBP.

INTERVENTIONS

The PA intervention included stretching, strengthening, and aerobic activities; CBT-P covered activity pacing, relaxation techniques, and cognitive restructuring.

MEASUREMENTS

Feasibility measures included enrollment and completion metrics; acceptability was measured by completed phone calls. Primary outcomes included the Timed "Up & Go" Test and the PROMIS Health Assessment Questionnaire. Generalized linear mixed models were used to estimate changes within and between groups. Effect sizes were calculated with the Cohen d. Adverse effects were measured by self-report.

RESULTS

The mean participant age was 70.3 years; 53% were not white, and 93% were men. Eighty-three percent of participants completed the study, and the mean number of completed phone calls was 10 (of 13). Compared with the results for the WL group, small to medium treatment effects were found for the intervention groups in the Timed "Up & Go" Test (PA group: -2.94 [95% CI = -6.24 to 0.35], effect size = -0.28; PA + CBT-P group: -3.26 [95% CI = -6.69 to 0.18], effect size = -0.31) and the PROMIS Health Assessment Questionnaire (PA group: -6.11 [95% CI = -12.85 to 0.64], effect size = -0.64; PA + CBT-P group: -4.10 [95% CI = -11.69 to 3.48], effect size = -0.43). Small treatment effects favored PA over PA + CBT-P. No adverse effects were noted.

LIMITATIONS

This was a pilot study, and a larger study is needed to verify the results.

CONCLUSIONS

This pilot trial demonstrated that home-based telephone-supported PA interventions were feasible, acceptable, and safe for older adult veterans. The results provide support for a larger trial investigating these interventions.

Effective treatment options for musculoskeletal pain in primary care: A systematic overview of current evidence

BACKGROUND & AIMS

Musculoskeletal pain, the most common cause of disability globally, is most frequently managed in primary care. People with musculoskeletal pain in different body regions share similar characteristics, prognosis, and may respond to similar treatments. This overview aims to summarise current best evidence on currently available treatment options for the five most common musculoskeletal pain presentations (back, neck, shoulder, knee and multi-site pain) in primary care.

METHODS

A systematic search was conducted. Initial searches identified clinical guidelines, clinical pathways and systematic reviews. Additional searches found recently published trials and those addressing gaps in the evidence base. Data on study populations, interventions, and outcomes of intervention on pain and function were extracted. Quality of systematic reviews was assessed using AMSTAR, and strength of evidence rated using a modified GRADE approach.

RESULTS

Moderate to strong evidence suggests that exercise therapy and psychosocial interventions are effective for relieving pain and improving function for musculoskeletal pain. NSAIDs and opioids reduce pain in the short-term, but the effect size is modest and the potential for adverse effects need careful consideration. Corticosteroid injections were found to be beneficial for short-term pain relief among patients with knee and shoulder pain. However, current evidence remains equivocal on optimal dose, intensity and frequency, or mode of application for most treatment options.

CONCLUSION

This review presents a comprehensive summary and critical assessment of current evidence for the treatment of pain presentations in primary care. The evidence synthesis of interventions for common musculoskeletal pain presentations shows moderate-strong evidence for exercise therapy and psychosocial interventions, with short-term benefits only from pharmacological treatments. Future research into optimal dose and application of the most promising treatments is needed.

Less Exercise and More Drugs: How a Low-Income Population Manages Chronic Pain

OBJECTIVES

To evaluate chronic pain management in a multistate, low-income Hispanic population, and to examine predictors of exercising and prescription pain medication (PPM) use.

DESIGN

Online survey administered to a representative sample of Hispanic adults in June 2015.

SETTING

Five southwestern states.

PARTICIPANTS

Among all online panel members who were Hispanic (N=1007), aged 35 to 75 years from 5 states, representing 11,016,135 persons, the survey was completed by 516 members (51%). Among these, 102 participants were identified with chronic noncancer pain representing 1,140,170 persons.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Exercising or using PPM for chronic pain in past year.

RESULTS

Most participants reported using PPM (58%) and exercise (54%) to manage pain. Compared with annual household incomes >$75,000, adjusted odds ratios [AORs] for exercising were .20 for <$10,000 (P=.12); .40 for $10,000 to $34,999 (P=.22); and .15 for $35,000 to $74,999 (P=.015). Conversely, AORs for PPM were over 4-fold higher for lower-income groups as follows: 14.2, 4.79, and 4.85, respectively (all P<.065). PPM users rated the importance of accessing a gym to manage pain lower (P=.01), while exercisers rated the feasibility of gym access to manage pain higher (P=.001).

CONCLUSIONS

In a Hispanic population-based sample with chronic pain, lower-income groups tended to exercise less but use PPM more. Barriers to gym access and use may play a role in these disparities.

Do expectancies of return to work and Job satisfaction predict actual return to work in workers with long lasting LBP?

Background

Musculoskeletal disorders including low back pain have major individual and socioeconomic consequences as it often leads to disability and long-term sick leave and exclusion from working life. Predictors of disability and return to work often differ, and the dominant knowledge is on predictors for prolonged sick leave and disability. Therefore it is also important to identify key predictors for return to work. The aim of the study was to assess if overall job satisfaction and expectancies of return to work predicts actual return to work after 12 months, among employees with long lasting low back pain, and to assess if there were gender differences in the predictors.

Methods

Data from the Cognitive interventions and nutritional supplements trial (CINS Trial) was used. Predictors for return to work were examined in 574 employees that had been on sick leave 2–10 months for low back pain, before entering the trial. Data were analysed with multiple logistic regression models stratified by gender, and adjusted for potential confounders.

Results

Regardless of gender high expectancies were a strong and significant predictor of return to work at 12 months, while high levels of job satisfaction were not a significant predictor. There were no differences in the levels of expectancies or overall job satisfaction between men and women. However, men had in general higher odds of returning to work compared with women.

Conclusions

Among individuals with long lasting low back pain high expectancies of returning to work were strongly associated with successful return to work. We do not know what factors influence individual expectancies of return to work. Screening expectancies and giving individuals with low expectancies interventions with a goal to change expectancies of return to work, such as CBT or self-management interventions, may contribute to increase actual return to work.

Reduction in sick leave by a workplace educational low back pain intervention: A cluster randomized controlled trial

Aims: The aim of this study was to investigate whether a workplace educational low back pain intervention had an effect on sick leave at the individual level and to identify possible predictors of the effect of intervention. Methods: Work units in two municipalities were cluster randomized to (a) educational meetings and peer support (45 units), (b) educational meetings, peer support and access to an outpatient clinic if needed (48 units) or (c) a control group (42 units). Both intervention groups attended educational meetings with information about back pain based on a non-injury model. A peer adviser was selected from among their colleagues. The outcome was days of sick leave at the individual level at 3, 6, 9 and 12 months, adjusting for previous sick leave at the unit level. As a result of similar effects on sick leave, the two intervention groups were merged (n=646) and compared with the control group (n=211). The predictors were different levels of belief in back pain myths, pain-related fear, helplessness/hopelessness and low back pain. Results: The intervention group had significantly less days of sick leave at the three month (4.9 days, p=0.001) and six month (4.4 days, p=0.016) follow ups compared with the control group. At three months, a low level of pain-related fear was the only predictor for the intervention effect (8.0 less days of sick leave, p<0.001). Conclusions: A workplace educational back pain intervention had an effect on sick leave for up to six months. A low score on pain-related fear was a predictor of the intervention effect.

Getting "Unstuck": A Multi-Site Evaluation of the Efficacy of an Interdisciplinary Pain Intervention Program for Chronic Low Back Pain

Chronic low back pain is one of the major health problems in the U.S., resulting in a large number of years of disability. To address the biopsychosocial nature of pain, interdisciplinary pain programs provide integrated interventions by an interdisciplinary team in a unified setting with unified goals. This study examined outcomes of an interdisciplinary program located at two sites with different staff, yet with a unified model of treatment and documentation. Efficacy at the combined sites was examined by comparing standard measures obtained upon admission to the program with measures at completion of a 3-4 week long program for 393 patients with chronic low back pain (CLBP). Repeated measures included pain severity, pain interference, efficacy of self-management strategies, hours of activity, depression, ability to do ADLs, and physical endurance. All repeated measures differed at the p < 0.001 level, with large effect sizes (0.66-0.85). Eighty-two percent of graduates reported being "very much improved" or "much improved". A second analyses provided evidence that treatment effects were robust across sites with no differences (<0.001) found on five of seven selected outcome measures. A third analysis found that number of days of treatment was correlated on three of seven measures at the <0.01 level. However, the amount of variance explained by days of treatment was under 5% on even the most highly correlated measure. These finding are consistent with previous research and explore short-term effectiveness of treatment across treatment sites and with variable duration of treatment.

Discrete Pathophysiology is Uncommon in Patients with Nonspecific Arm Pain

BACKGROUND

Nonspecific symptoms are common in all areas of medicine. Patients and caregivers can be frustrated when an illness cannot be reduced to a discrete pathophysiological process that corresponds with the symptoms. We therefore asked the following questions: 1) Which demographic factors and psychological comorbidities are associated with change from an initial diagnosis of nonspecific arm pain to eventual identification of discrete pathophysiology that corresponds with symptoms? 2) What is the percentage of patients eventually diagnosed with discrete pathophysiology, what are those pathologies, and do they account for the symptoms?

METHODS

We evaluated 634 patients with an isolated diagnosis of nonspecific upper extremity pain to see if discrete pathophysiology was diagnosed on subsequent visits to the same hand surgeon, a different hand surgeon, or any physician within our health system for the same pain.

RESULTS

There were too few patients with discrete pathophysiology at follow-up to address the primary study question. Definite discrete pathophysiology that corresponded with the symptoms was identified in subsequent evaluations by the index surgeon in one patient (0.16% of all patients) and cured with surgery (nodular fasciitis). Subsequent doctors identified possible discrete pathophysiology in one patient and speculative pathophysiology in four patients and the index surgeon identified possible discrete pathophysiology in four patients, but the five discrete diagnoses accounted for only a fraction of the symptoms.

CONCLUSION

Nonspecific diagnoses are not harmful. Prospective randomized research is merited to determine if nonspecific, descriptive diagnoses are better for patients than specific diagnoses that imply pathophysiology in the absence of discrete verifiable pathophysiology.

Preoperative cognitive-behavioural intervention improves in-hospital mobilisation and analgesic use for lumbar spinal fusion patients

BACKGROUND

Catastrophic thinking and fear-avoidance belief are negatively influencing severe acute pain following surgery causing delayed ambulation and discharge. We aimed to examine if a preoperative intervention of cognitive-behavioural therapy (CBT) could influence the early postsurgical outcome following lumbar spinal fusion surgery (LSF).

METHODS

Ninety patients undergoing LSF due to degenerative spinal disorders were randomly allocated to either the CBT group or the control group. Both groups received surgery and postoperative rehabilitation. In addition, the CBT group received a preoperative intervention focussed on pain coping using a CBT approach. Primary outcome was back pain during the first week (0-10 scale). Secondary outcomes were mobility, analgesic consumption, and length of hospitalisation. Data were retrieved using self-report questionnaires, assessments made by physical therapists and from medical records.

RESULTS

No difference between the groups' self-reported back pain (p = 0.76) was detected. Independent mobility was reached by a significantly larger number of patients in the CBT group than the control group during the first three postoperative days. Analgesic consumption tended to be lower in the CBT group, whereas length of hospitalisation was unaffected by the CBT intervention.

CONCLUSION

Participation in a preoperative CBT intervention appeared to facilitate mobility in the acute postoperative phase, despite equally high levels of self-reported acute postsurgical pain in the two groups, and a slightly lower intake of rescue analgesics in the CBT group. This may reflect an overall improved ability to cope with pain following participation in the preoperative CBT intervention.

TRIAL REGISTRATION

The study was approved by the Danish Protection Agency (2011-41-5899) and the Ethics Committee of the Central Denmark Region (M-20110047). The trial was registered in Current Controlled Trials ( ISRCTN42281022 ).

[Non-randomised trial of an educational intervention based on cognitive-behavioural principles for patients with chronic low back pain attended in Primary Care Physiotherapy]

Objetivo

Valorar la influencia de una intervención educativa en la reducción del «miedo-evitación» (ME) y del «catastrofismo al dolor» (CAT) en población con lumbalgia crónica inespecífica (LCI) atendida en fisioterapia de atención primaria (AP).

Diseño

Estudio cuasiexperimental.

Emplazamiento

Centros de salud (CS) del Distrito Sanitario Costa del Sol.

Participantes

Pacientes con LCI entre 18-65 años con comprensión del idioma español; ausencia de intervenciones educativas paralelas; ausencia de banderas rojas; ausencia de deterioro cognitivo y/o fibromialgia; ausencia de cirugía dorsolumbar, y tolerancia al ejercicio físico.

Intervenciones

El grupo control recibió la EdE grupal habitual. El experimental recibió, además, un instrumento escrito para lectura domiciliaria, más la posterior puesta en común, aclaración de dudas y reestructuración de creencias y metas durante el desarrollo de las sesiones. Ambas intervenciones duraron unos 280 min (7 sesiones de 40 min).

Resultados

Las variables principales incluyeron ME y CAT. Secundariamente se valoraron dolor y discapacidad. Algunas variables «sociodemográficas» y «relacionadas con el trastorno» fueron tenidas en cuenta en el análisis.

Se observaron diferencias estadísticamente significativas en el grupo experimental versus control en la variación del ME −14 (−25,5; 0) vs −4 (−13; 0) (p = 0,009), y del CAT −9 (−18; −4) vs −4,5 (−8,25; 0) (p = 0,000). Igualmente se observaron diferencias en discapacidad (p = 0,046), pero no en dolor (p = 0,280).

Conclusiones

Los resultados deben ser considerados a la luz de las posibles limitaciones que plantea el estudio. Su naturaleza pragmática permitiría una potencial transferencia a la dinámica asistencial habitual.

Using health trainers to promote self-management of chronic pain: can it work?

BACKGROUND

In 2011, the Sheffield Primary Care Trust piloted a Health Trainer (HT) programme targeted specifically to people with chronic pain. The programme aimed to determine whether patients presenting to primary care with chronic pain would benefit from self-management support, thereby reducing the burden on primary care and secondary care services.

METHODS

We conducted a formative mixed-methods evaluation of the pilot programme, focusing on four aspects of implementation: general practitioner (GP) referral to the programme, HT's ability to use cognitive behavioural (CB) approaches, short-term outcomes for clients and adequacy of resources. Qualitative data were collected via interviews with GPs, HTs and the chronic pain team; supervision sessions with HTs; and client case studies. Quantitative data were collected on satisfaction with training, HT's self-reported confidence to implement CB and clients' self-rated well-being before and after participation.

RESULTS

A total of 143 clients with pain for 1 year or more were referred, exceeding the projected 90 referrals by over 50%. A total of 70% of the clients came from the most deprived areas of Sheffield, 40% were listed as permanently sick/disabled and only 20% were working. Qualitative analysis indicated that the CB training was delivered as intended. Clients reported that 75% of their goals were either achieved or partly achieved, and at follow-up 43% of them reported maintaining strategies for self-management. Financial resources were supplemented by indirect resources, including GP 'champions' with a special interest in pain, and a multidisciplinary chronic pain team. The prior history of working with community organizations was critical in ensuring credibility in client communities and addressing client needs.

CONCLUSION

A HT programme promoting self-management of chronic pain can be successfully implemented when supported by community organisations. Preliminary data indicate that the programme can be instrumental in helping clients to actively participate in identifying their own problems, set achievable goals for self-management and successfully manage the challenges of everyday life.

SUMMARY POINTS

Community-based Health Trainer programmes can be successfully established to promote self-management of chronic pain among clients in the deprived areas using multidisciplinary pain management teams. Utilising a community organization infrastructure that has experience of delivering successful programmes was instrumental in ensuring credibility of the initiative and access for clients. Health trainers can integrate cognitive behavioral training with their existing skills to work with clients who have chronic pain.

Cognitive behavioral therapy for depression improves pain and perceived control in cardiac surgery patients

BACKGROUND

Depression after cardiac surgery (CS) is associated with increased pain and decreased sleep quality. While cognitive behavioral therapy (CBT) aimed at depression is effective in relieving depressive symptoms after cardiac surgery, little is known about its ability to ameliorate other common postoperative problems that affect recovery and quality of life.

AIMS

The purpose of this study was to evaluate the effects of CBT for depression on pain severity, pain interference, sleep, and perceived control in patients recovering from CS.

METHODS

Depressed patients recovering from CS were randomized to receive either eight weeks of CBT or usual care. At baseline and post-intervention, patients completed questionnaires for depressive symptoms, pain, sleep, and perceived control. Group comparisons were conducted using t-tests or chi square analysis. Repeated measures analysis was used to assess the effect of the intervention in changes over time.

RESULTS

The sample (n=53) included 16.9% women and had a mean age of 67.8±9.2 years. CBT for depression increased perceived control (p<0.001) and decreased pain interference (p=0.02) and pain severity (p=0.03). Group effects remained significant (p<0.05) for perceived control and pain interference and a trend was observed for pain severity (p<0.10) after controlling for variables that differed at baseline. There were no group differences in sleep disturbance over time.

CONCLUSIONS

A depression-focused CBT intervention yields benefits in other common postoperative problems, specifically improved perceived control and decreased pain in depressed cardiac surgery patients.

Individualised cognitive functional therapy compared with a combined exercise and pain education class for patients with non-specific chronic low back pain: study protocol for a multicentre randomised controlled trial

INTRODUCTION

Non-specific chronic low back pain (NSCLBP) is a very common and costly musculoskeletal disorder associated with a complex interplay of biopsychosocial factors. Cognitive functional therapy (CFT) represents a novel, patient-centred intervention which directly challenges pain-related behaviours in a cognitively integrated, functionally specific and graduated manner. CFT aims to target all biopsychosocial factors that are deemed to be barriers to recovery for an individual patient with NSCLBP. A recent randomised controlled trial (RCT) demonstrated the superiority of individualised CFT for NSCLBP compared to manual therapy combined with exercise. However, several previous RCTs have suggested that class-based interventions are as effective as individualised interventions. Therefore, it is important to examine whether an individualised intervention, such as CFT, demonstrates clinical effectiveness compared to a relatively cheaper exercise and education class. The current study will compare the clinical effectiveness of individualised CFT with a combined exercise and pain education class in people with NSCLBP.

METHODS AND ANALYSIS

This study is a multicentre RCT. 214 participants, aged 18-75 years, with NSCLBP for at least 6 months will be randomised to one of two interventions across three sites. The experimental group will receive individualised CFT and the length of the intervention will be varied in a pragmatic manner based on the clinical progression of participants. The control group will attend six classes which will be provided over a period of 6-8 weeks. Participants will be assessed preintervention, postintervention and after 6 and 12 months. The primary outcomes will be functional disability and pain intensity. Non-specific predictors, moderators and mediators of outcome will also be analysed.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Mayo General Hospital Research Ethics Committee (MGH-14-UL). Outcomes will be disseminated through publication according to the SPIRIT statement and will be presented at scientific conferences.

Cost-utility of cognitive behavioral therapy for low back pain from the commercial payer perspective

STUDY DESIGN

Markov cost-utility model.

OBJECTIVE

To evaluate the cost-utility of cognitive behavioral therapy (CBT) for the treatment of persistent nonspecific low back pain (LBP) from the perspective of US commercial payers.

SUMMARY OF BACKGROUND DATA

CBT is widely deemed clinically effective for LBP treatment. The evidence is suggestive of cost-effectiveness.

METHODS

We constructed and validated a Markov intention-to-treat model to estimate the cost-utility of CBT, with 1-year and 10-year time horizons. We applied likelihood of improvement and utilities from a randomized controlled trial assessing CBT to treat LBP. The trial randomized subjects to treatment but subjects freely sought health care services. We derived the cost of equivalent rates and types of services from US commercial claims for LBP for a similar population. For the 10-year estimates, we derived recurrence rates from the literature. The base case included medical and pharmaceutical services and assumed gradual loss of skill in applying CBT techniques. Sensitivity analyses assessed the distribution of service utilization, utility values, and rate of LBP recurrence. We compared health plan designs. Results are based on 5000 iterations of each model and expressed as an incremental cost per quality-adjusted life-year.

RESULTS

The incremental cost-utility of CBT was $7197 per quality-adjusted life-year in the first year and $5855 per quality-adjusted life-year over 10 years. The results are robust across numerous sensitivity analyses. No change of parameter estimate resulted in a difference of more than 7% from the base case for either time horizon. Including chiropractic and/or acupuncture care did not substantively affect cost-effectiveness. The model with medical but no pharmaceutical costs was more cost-effective ($5238 for 1 yr and $3849 for 10 yr).

CONCLUSION

CBT is a cost-effective approach to manage chronic LBP among commercial health plans members. Cost-effectiveness is demonstrated for multiple plan designs.

[A complex approach to the treatment of patients with chronic lumbalgia]

The management of patients with chronic non-specific low-back pain (chronic lumbalgia) is an urgent problem of current medicine. We report two cases of patients with chronic lumbalgia and severe comorbid diseases who demonstrated good results after the complex treatment including pharmacotherapy, cognitive-behavioral therapy and exercise treatment.

Mental health treatment after major surgery among Vietnam-era Veterans with posttraumatic stress disorder

The purpose of this study was to examine mental health treatment use among Vietnam Veterans with posttraumatic stress disorder and determine whether undergoing major surgery interrupted mental health treatment or increased the risk of psychiatric hospitalization. Using retrospective data from Veterans Health Administration’s electronic medical record system, a total of 3320 Vietnam-era surgery patients with preoperative posttraumatic stress disorder were identified and matched 1:4 with non-surgical patients with posttraumatic stress disorder. The receipt of surgery was associated with a decline in overall mental health treatment and posttraumatic stress disorder–specific treatment 1 month following surgery but not during any subsequent month thereafter. Additionally, surgery was not associated with psychiatric admission.

[Design of an educational tool for Primary Care patients with chronic non-specific low back pain]

Evidencias científicas actuales sobre el manejo de la lumbalgia crónica inespecífica ponen de relieve los beneficios del ejercicio físico. Este objetivo es frecuentemente minado por déficits educativos en materias relacionadas con la naturaleza multifactorial y benigna del dolor lumbar inespecífico, los cuales constituyen auténticos factores de riesgo psicosocial para la cronificación. Su perversa influencia podría interferir no solo con la decisión individual de adoptar conductas de afrontamiento más adaptativas, sino también, con los mecanismos endógenos de neuromodulación del dolor. Así, las estrategias educativas y el control de dichos factores se han convertido en objetivos relevantes a incorporar en el manejo del trastorno y en las directrices de investigación. Este trabajo presenta los modelos teóricos y las bases científicas sobre los que se ha sustentado el diseño de un instrumento educativo para pacientes con lumbalgia crónica inespecífica atendidos en Fisioterapia de Atención Primaria. Su estructuración, contenido y objetivos también son presentados.

Arm ache

Both patients and providers hope for better management strategies for nonspecific activity-related upper limb pain (herein referred to as "arm ache"). The next innovation in the care of arm ache may arise from the strong evidence that mood, coping strategies (e.g., catastrophic thinking), and heightened illness concern-all very responsive to treatment with cognitive behavioral therapy-account for a large percentage of the variation in symptom intensity and magnitude of disability. This focus on treatments to reduce symptoms and disability represents a change in culture for patients and providers, both of whom are accustomed to the biomedical framework that anticipates a direct correspondence between illness (the state of being unwell) and disease (pathophysiology). Not all patients are ready for such an approach, but as a first step health providers can prioritize empathy; remain mindful that words, illness concepts, and treatments can reinforce ineffective coping strategies; and encourage curiosity about the human illness experience.

Biologically based therapy for the intervertebral disk: who is the patient?

The intervertebral disk (IVD) is a fascinating and resilient tissue compartment given the myriad of functions that it performs as well as its unique anatomy. The IVD must tolerate immense loads, protect the spinal cord, and contribute considerable flexibility and strength to the spinal column. In addition, as a consequence of its anatomical and physiological configuration, a unique characteristic of the IVD is that it also provides a barrier to metastatic disease. However, when injured and/or the subject of significant degenerative change, the IVD can be the source of substantial pain and disability. Considerable efforts have been made over the past several decades with respect to regenerating or at least modulating degenerative changes affecting the IVD through the use of many biological agents such as growth factors, hydrogels, and the use of plant sterols and even spices common to Ayurvedic medicine. More recently stem/progenitor and autologous chondrocytes have been used mostly in animal models of disk disease but also a few trials involving humans. At the end of the day if biological therapies are to offer benefit to the patient, the outcomes must be improved function and/or less pain and also must be improvements upon measures that are already in clinical practice. Here some of the challenges posed by the degenerative IVD and a summary of some of the regenerative attempts both in vitro and in vivo are discussed within the context of the vital question: "Who is the patient?"
