Behavioural therapy for chronic low back pain

Three Part Question

[In patients with chronic low back pain] is [behavioural therapy better than other conservative treatments] at [reducing pain and increasing function]

Clinical Scenario

A 55 year old man attends his GP with ongoing simple low back pain. He has no red flag symptoms and has tried analgesics in the past. You assess him and he tells you that he is very concerned about his pain and is very worried that he is doing more damage by continuing to work. You try and reassure him but wonder if some formal behaviour therapy might benefit him.

RCTs and systematic reviews of behavioural therapy in low back pain.Systematic reviewNumber of papers found21 studies were found relevant to the reviewA wellconducted systematic review. The differences are most marked against no-intervention controls. It would appear to show benefit, but whether it is better than anything else is not determined by this review.
Quality of papers7 (33%) were considered high quality studies
Respondant therapy (progressive relaxation) treatment versus waiting list controlsModerate evidence for pregressive relaxation on pain and behavioural outcomes in the short term. Limited evidence for progressive relaxation benefiting generic functional status. Medium positie effect of progressive relaxation on back-specific functional status.
Respondent therapy (EMG biofeedback) versus waiting list controlsThere is moderate evidence (3 trials, 88 people) that there is no significant difference between EMG biofeedback and waiting list control on behavioural outcomes in the short-term. There is conflicting evidence (2 trials, 60 people) on the effectiveness of EMG versus waiting list control on general functional status. Furthermore, there is limited evidence (1 trial, 28 people) for a small short-term positive effect of EMG biofeedback on back specific functional status.
Operant therapy versus waiting list controlsThere is strong evidence (2 trials, 87 people) that there is no difference between operant therapy and waiting list control on general functional status on the short-term. There is no evidence (level 4) regarding the effectiveness of operant therapy on back-specific functional status.
Combined respondent and cognitive therapy versus waiting list controlsThere is strong evidence (4 trials, 134 people) that there are no differences between combined respondent and cognitive therapy and the waiting list control on behavioural outcomes and general functional status in the short term
Cognitive versus operant therapyThere is limited evidence (1 trial, 20 people) that there are no differences between cognitive and operant therapy.
Cognitive versus respondent therapyThere is moderate evidence (2 trials, 67 people) that there are no significant differences between the effects of respondent and cognitive therapy on improving pain intensity, generic functional status, or behavioural outcomes.
Operant versus respondent therapyThere is no evidence
Cognitive-behavioural versus cognitive therapyThere is limited evidence (1 trial, 33 people) that there are no differences in the short-term or long-term outcomes between groups receiving cognitive-behavioural or cognitive therapy.
Cognitive-behavioural versus operant therapyCognitive-behavioural versus operant therapy
Cognitive-behavioural versus respondent therapyThere is limited evidence (1 trial, 28 people) that there are no differences in either the short-term or long-term effectiveness between cognitive-behavioural and respondent therapy.
Behavioural treatment versus other kinds of treatmentThere is limited evidence (1 trail, 39 people) that there are no differences between behavioural treatment and exercises.
Behavioural treatment in addition to another treatment versus the other treatment aloneThere is moderate evidence (6 trials, 210 people) that there are no significant differences in the short-term or long-term effectiveness of the addition of behavioural components to usual treatment programs for CLBP on pain intensity, generic functional status and behavioural outcomes.

51 patients with chronic low back pain. aged 18-65. Pain longer than 3 months. Access to internet. Prior assessmen tby physician. Randomised to either waiting list control or 8 week internet based pain management program. Intervention assessed against a coping strategies questionnaire, Multidimendsional pain inventory and hopital anxiety and depression scale.Randomised controlled trialFollow up92% follow up at 3 monthsSelect population. Small numbers. Multiple analyses not accounted for. Probably an excess of subgroup analyses.
CSQBetter for intervention. MANOVA p=o.o47

HADSNo difference

185 patients seeking care for nonspecific low back pain. Thought to be at risk of prolonged absenteeism. Recruited after being declined for surgery. The intervention group had a 5 day course. Follow up lasted 12 months.Randomised controlled trial.Follow up165 approached. 152 randomised. 123 completed 12 month follow up.Rather select group of participants. Exercise was a major component of the intervention as well as cognitive training. Only self reported data used.
PainNo difference in pain scores at 3 (RR 1.02) or 12 (RR 0.98) months.
Coping strategiesat 3 months coping was better in the intervention group (53.8% vs. 31.6%). At 12 months it was 61% and 28.6%.
Physical fitness and exerciseNo significant differences found.

221 patients with long term nonspecific low back pain. Sick listed from between 1 and 6 months. The intervention included psychological, ergonomic, medical and physiological education, workplace visits. Interventions initially lasted 4 weeks with subsequent booster sessions. Patients received cognitive-orientated physiotherapy(PT), cognitive behaviour therapy (CBT), full time behavioural medicine rehabilitation(BM i.e. both CBT and PT) or normal care. Follow up was for 3 years.Randomised Controlled TrialAbscence from work in average daysBetter for combined treatment. In women BM=439, PT=522, CBT=542, CG=572. In men BM=494, PT=541, CBT=629. Differences only significant in women.Some arguments circular, in that the intervention groups consulted health care less, but had already had an intervention by health care. Most analysis between full vs. no intervention. Less information available on the other two intervention groups.
Health related quality of lifeNo formal testing done due to low response.
Health care utilisationNumerous analyses, few differences.

Comment(s)

Back pain is increasingly recognised as a major problem in Western societies. There is increasing evidence that a purely medical/interventionalist approach is insufficient and that the problem must be treated in the round. A biopsychsocial approach to the problem is now regularly advocated, and a component of this is usually some form of behaviour therapy. This review shows that there is evidence to support behavious therapy in the management of low back pain. However, as with many other interventions in chronic low back pain the benefits cannot be described as dramatic.

Clinical Bottom Line

There is evidence to support the role of behaviour therapy in the management of chronic nonspecific low back pain.
