Network meta-analysis identifies best psychosocial interventions for chronic low back pain

Cognitive behavioural therapy combined with physical therapy was most beneficial for physical function and alleviating fear of movement.

Guidelines for treating patients with chronic, nonspecific low back pain (LBP) recommend both exercise and psychosocial therapies, but the comparative effectiveness of psychological interventions for LBP is unknown. Researchers conduc­ted a network meta­-analysis of 97 rando­mised controlled trials in which different psychological interventions (alone or in combination with other treatments) were compared with nonpsychological inter­ventions (e.g. physical therapy, generalist care, no treatment) in more than 13,000 adults with chronic, nonspecific LBP.

Compared with physical therapy alone, cognitive behavioural therapy (CBT) plus physical therapy was most effective for improving physical function (mean difference, 20 points on a standardised 100­ point scale) within two months after treatment (i.e. postintervention), but the effect diminished thereafter. Pain education plus physical therapy had a more modest but more sustained benefit. For reducing postintervention pain intensity, compared with physical therapy alone, behavioural therapy (without a cognitive component) with physical therapy was most effective (mean difference, 27 points), and the benefit was sustained for as long as 12 months. For alleviating postintervention fear of move­ment, compared with physical therapy alone, CBT plus physical therapy was most effective (mean difference, 47 points), with benefit sustained for more than 12 months.

Comment: These data might help clinicians better tailor psychosocial interventions to individual patients with LBP, based on specific symptoms and goals. The authors note the challenges of delivering often­ siloed interventions without overly fragmenting care and suggest possible strategies for more effective intradisci­plinary versatility and interdisciplinary collaboration.
