Preventing incapacity in people with musculoskeletal disorders.

Musculoskeletal disorders are among the most common causes of sickness absence, long-term incapacity for work and ill-health retirement. The number of Incapacity Benefit (IB) recipients in the United Kingdom has trebled since 1979, despite improvement in objective measures of health. Most of the trend is in non-specific conditions (largely subjective complaints, often with little objective pathology or impairment). Understanding incapacity requires a biopsychosocial model that addresses all the physical, psychological and social factors involved in human illness and disability. Rehabilitation should be directed to overcome biopsychosocial obstacles to recovery and return to work. These principles are fundamental to better clinical and occupational management and minimizing incapacity. Sickness absence and incapacity from non-specific musculoskeletal conditions could be reduced by 33-50%, but that depends on getting all stakeholders onside and a fundamental shift in thinking about these conditions-in health care, in the workplace and in society.

A population-based survey of back pain beliefs in Canada.

STUDY DESIGN: Population-based survey. OBJECTIVES: To assess the back pain beliefs in 2 provinces in Canada to inform a population-based educational campaign. SUMMARY OF BACKGROUND DATA: Beliefs, attitudes, and recovery expectations appear to influence recovery from back pain, yet prevailing public opinions about the condition have been little studied. METHODS: Telephone surveys were conducted with 2400 adults in 2 Canadian provinces. Surveys included the Back Beliefs Questionnaire, and additional questions concerning age, gender, recent and lifetime back pain, coping strategies for back pain, and awareness and persuasiveness of media information concerning back pain. RESULTS: A high prevalence of back pain was reported, with a lifetime prevalence of 83.8%, and 1-week prevalence of 34.2%. Generally, a pessimistic view of back pain was held. Most agreed that back pain makes everything in life worse, will eventually stop one from working, and will become progressively worse with age. Mixed opinions were observed regarding the importance of rest and staying active. A significant minority (12.3%) reported taking time off from work for their last back pain episode. Those individuals taking time off from work held more negative back pain beliefs, including the belief that back pain should be rested until it gets better. CONCLUSIONS: Public back pain beliefs in the 2 Canadian provinces sampled are not in harmony with current scientific evidence for this highly prevalent condition. Given the mismatch between public beliefs and current evidence, strategies for reeducating the public are needed.

Surgery for degenerative lumbar spondylosis: updated Cochrane Review.

STUDY DESIGN: An updated Cochrane review. OBJECTIVE: To review current scientific evidence on the effectiveness of surgical interventions for degenerative lumbar spondylosis. SUMMARY OF BACKGROUND DATA: There is still limited scientific evidence on spinal surgery. METHODS: Use of standard Cochrane review methods to analyze all randomized controlled trials published to March 31, 2005. RESULTS: A total of 31 randomized controlled trials were identified. Most of the earlier trials reported mainly surgical outcomes; more of the recent trials also reported patient-centered outcomes of pain or disability. There is still very little information on occupational outcomes or long-term outcomes beyond 2-3 years. Seven heterogeneous trials on spondylolisthesis, spinal stenosis, and nerve compression permitted limited conclusions. There were two new trials on fusion that showed conflicting results. One trial showed that fusion gave better clinical outcomes than conventional physiotherapy, and the other showed that fusion was no better than a modern exercise and rehabilitation program. There were 8 trials that showed that instrumented fusion produces a higher fusion rate, but any improvement in clinical outcomes is probably marginal. CONCLUSIONS: No conclusions are possible about the relative effectiveness of anterior, posterior, or circumferential fusion. The preliminary results of three small trials of intradiscal electrotherapy suggest it is ineffective, except possibly in highly selected patients. Preliminary data from three trials of disc arthroplasty do not permit firm conclusions.

Concepts of rehabilitation for the management of low back pain.

This chapter develops rehabilitation principles for the clinical and occupational management of non-specific low back pain (LBP). Rehabilitation has traditionally been a secondary intervention, which focused on permanent impairment, but this is inappropriate for LBP. Most patients with LBP do not have any irremediable impairment and long-term incapacity is not inevitable: given the right care, support and opportunity, most should be able to return to work. Rehabilitation should then address obstacles to recovery and barriers to (return to) work. Rehabilitation should not be a separate, second stage after 'treatment' is complete: rehabilitation principles should be integral to clinical and occupational management. It should be possible to reduce sickness absence and long-term incapacity due to LBP by at least 30-50%, but this will require a fundamental shift in management culture.

Rehabilitation following first-time lumbar disc surgery: a systematic review within the framework of the cochrane collaboration.

STUDY DESIGN: A systematic review of randomized controlled trials. BACKGROUND: Although several rehabilitation programs, physical fitness programs, or protocols regarding instruction for patients to return to work after lumbar disc surgery have been suggested, little is known about the efficacy of these treatments, and there are still persistent fears of causing reinjury, reherniation, or instability. OBJECTIVES: The objective of this systematic review was to evaluate the effectiveness of active treatments that are used in the rehabilitation after first-time lumbar disc surgery. METHODS: The authors searched the MEDLINE, Embase, and Psyclit databases up to April 2000 and the Cochrane Controlled Trials Register 2001, issue 3. Both randomized and nonrandomized controlled trials on any type of active rehabilitation program after first-time disc surgery were included. Two independent reviewers performed the inclusion of studies, and two other reviewers independently performed the methodologic quality assessment. A rating system that consists of four levels of scientific evidence summarizes the results. RESULTS: Thirteen studies were included, six of which were of high quality. There is no strong evidence for the effectiveness for any treatment starting immediately postsurgery, mainly because of the lack of good quality studies. For treatments that start 4 to 6 weeks postsurgery, there is strong evidence (level 1) that intensive exercise programs are more effective on functional status and faster return to work (short-term follow-up) as compared to mild exercise programs, and there is strong evidence (level 1) that on long-term follow-up there is no difference between intensive exercise programs and mild exercise programs with regard to overall improvement. For all other primary outcome measures for the comparison between intensive and mild exercise programs, there is conflicting evidence (level 3) with regard to long-term follow-up. Furthermore, there is no strong evidence for the effectiveness of supervised training as compared to home exercises. There is also no strong evidence for the effectiveness of multidisciplinary rehabilitation as compared to usual care. There is limited evidence (level 3) that treatments in working populations that aim at return to work are more effective than usual care with regard to return to work. Also, there is limited evidence (level 3) that low-tech and high-tech exercises, started more than 12 months postsurgery, are more effective in improving low-back functional status as compared to physical agents, joint manipulations, or no treatment. Finally, there is no strong evidence for the effectiveness of any specific intervention when added to an exercise program, regardless of whether exercise programs start immediately postsurgery or later. None of the investigated treatments seem harmful with regard to reherniation or reoperation. CONCLUSIONS: There is no evidence that patients need to have their activities restricted after first-time lumbar disc surgery. There is strong evidence for intensive exercise programs (at least if started about 4-6 weeks postoperative) and no evidence they increase the reoperation rate. It is unclear what the exact content of postsurgery rehabilitation should be. Moreover, there are no studies that investigated whether active rehabilitation programs should start immediately postsurgery or possibly 4 to 6 weeks later.

Public perceptions about low back pain and its management: a gap between expectations and reality?

OBJECTIVE: To compare public perceptions and patient perceptions about back pain and its management with current clinical guidelines. DESIGN: A survey using a quota sampling technique. SETTING: On-the-street in South Derbyshire in the UK. SUBJECTS: 507 members of the general population aged between 20 and 60 years, including a representative subsample of 40% who had experienced back pain in the previous year. SURVEY: To test knowledge and perceptions of back pain and its best management using statements based on The Back Book which was produced in conjunction with the Royal College of General Practitioners and based on best available evidence. In addition expectations of back pain management and outcome were investigated. RESULTS: Forty percent of this sample had experienced back pain during the previous year, more than half of whom had consulted their GP. More than half believed the spine is one of the strongest part of the body, but nearly two thirds incorrectly believed that back pain is often due to a slipped disc or trapped nerve. Two thirds expected a GP to be able to tell them exactly what was wrong with their back, although slightly fewer among those who had consulted. Most expected to have an X-ray, especially if they had consulted. Most recognised that the most important thing a GP can do is offer reassurance and advice. The responses were not related to age, gender or social class. Those who had consulted appeared to have slightly more misconceptions: this could be partly due to people with more severe problems or more misconceptions being more likely to consult, but also suggests either that GPs are still giving inaccurate information or at least failing to correct these misconceptions. CONCLUSIONS: The problem of managing back pain might be reduced by closing the gap between the public's expectations and what is recommended in the guidelines through the promotion of appropriate health education messages. Further professional education of GPs also appears to be needed to update them in the most effective approach to managing back pain.

A Fear-Avoidance Beliefs Questionnaire (FABQ) and the role of fear-avoidance beliefs in chronic low back pain and disability.

Pilot studies and a literature review suggested that fear-avoidance beliefs about physical activity and work might form specific cognitions intervening between low back pain and disability. A Fear-Avoidance Beliefs Questionnaire (FABQ) was developed, based on theories of fear and avoidance behaviour and focussed specifically on patients' beliefs about how physical activity and work affected their low back pain. Test-retest reproducibility in 26 patients was high. Principal-components analysis of the questionnaire in 210 patients identified 2 factors: fear-avoidance beliefs about work and fear-avoidance beliefs about physical activity with internal consistency (alpha) of 0.88 and 0.77 and accounting for 43.7% and 16.5% of the total variance, respectively. Regression analysis in 184 patients showed that fear-avoidance beliefs about work accounted for 23% of the variance of disability in activities of daily living and 26% of the variance of work loss, even after allowing for severity of pain; fear-avoidance beliefs about physical activity explained an additional 9% of the variance of disability. These results confirm the importance of fear-avoidance beliefs and demonstrate that specific fear-avoidance beliefs about work are strongly related to work loss due to low back pain. These findings are incorporated into a biopsychosocial model of the cognitive, affective and behavioural influences in low back pain and disability. It is recommended that fear-avoidance beliefs should be considered in the medical management of low back pain and disability.

A comparison of cognitive measures in low back pain: statistical structure and clinical validity at initial assessment.

Four cognitive measures--MHLC, PLC, CSQ and PRSS/PRCS--were directly compared in 120 U.K. patients with chronic low back pain. 80% of the individual items in the PLC and 86% in the CSQ had satisfactory test-retest reliability, as had most of the scales of the CSQ and the PLC PC scale. The items and the scales of the MHLC and the PRSS/PRCS had lower reliability. The factor structures of the PLC and the PRSS/PRCS bore close similarity to the original descriptions. The CSQ structure was similar to the original but further investigation of its psychometric properties is required. The structure of the MHLC was not replicated. Considerable communality was found between the cognitive measures. The strongest relationship found in this study was between the CSQ and PRSS catastrophising scales and depressive symptoms. There was also a relationship among cognitive measures and both disability and work loss which persisted even after controlling for severity of pain and depressive symptoms. The present results suggest that the concept of catastrophising has greatest potential for understanding current low back symptoms and that the CSQ may be the most useful measure of this. Other work, however, suggests that the PLC may also be of value in following change and predicting response to treatment.

Clinical assessment and interpretation of abnormal illness behaviour in low back pain.

Patients with chronic low back pain present with a mixture of symptoms and signs. Some are a direct consequence of physical pathology whereas others are attributable to associated and appropriate psychological and behavioural changes. At times the latter may be out of keeping with the degree of physical pathology and thus have specific significance in terms of the affective and cognitive disturbances that are also present and which may be the basis for abnormal illness behaviour. In an attempt to demonstrate more clearly the relationship between physical, psychological and behavioural components of illness, this paper draws on two data sets in patients with low back pain. The first explores the relationship between behavioural symptoms and signs, objective physical impairment, pain and disability and psychometric measures of distress together with scales making up the illness behaviour questionnaire (IBQ) of Pilowsky and Spence. A second data set is used to assess the value of the IBQ in understanding how psychological distress and behavioural signs and symptoms are related to the outcome of surgical treatment. The results gained reveal that behavioural symptoms and signs are directly related to the physical severity of low back disorder, the patient's report of pain and disability and the outcome of surgical treatment. Scores on the IBQ were strongly related to measures of affective disturbance and psychological distress. More specifically the disease affirmation scale of the IBQ, incorporating scales for disease conviction and psychological versus somatic focussing was an important dimension in relation to the behavioural symptoms and signs, thereby confirming results gained by other workers. Disease conviction and lack of response to clinicians' reassurances regarding illness - a situation in which abnormal illness behaviour is often deemed to exist - should not be seen simply as a function of the disease process, but more as a psychological coping mechanism for certain individuals under stress. The significance of this observation is discussed in relation to decisions regarding the overall assessment of chronic pain patients and their treatment.

Psychometric construction and validity of the Pilowsky Illness Behaviour Questionnaire in British patients with chronic low back pain.

The psychometric construction and validity of the 62-item Illness Behaviour Questionnaire has been examined in a study of 200 British patients suffering from chronic low back pain. 25 of the 62 items were unsatisfactory. Three new scales (AHD, LD and SI) represented a statistical improvement on the original scales, but were of little additional value to established measures in the analysis of reported pain or disability. The results indicate the need to reconsider the nature of hypochondriasis and abnormal illness behaviour.
