Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain (RESTORE): 3-year follow-up of a randomised, controlled trial
Abstract
BACKGROUND
Interventions for low back pain typically produce small and short-term effects. Cognitive functional therapy (CFT) has shown large effects up to 12 months, but long-term effects are unclear. We aimed to compare the long-term (3-year) effectiveness of CFT, delivered with or without movement sensor biofeedback, with usual care for patients with chronic disabling low back pain.
METHODS
The RESTORE trial was a randomised, controlled, three-arm parallel group, phase 3, clinical trial that investigated CFT delivered with or without biofeedback compared with usual care for the treatment of chronic low back pain. Treatment was delivered in 20 primary care physiotherapy clinics in Australia. This study is the 3-year follow-up of the RESTORE trial. We recruited adults (aged ≥18 years) with low back pain lasting more than 3 months with at least moderate pain-related physical activity limitation and average back pain of at least 4 on a 0-10 scale. Participants were randomly assigned (1:1:1) via a centralised adaptive schedule to usual care, CFT only, or CFT plus biofeedback. At the 1-year follow-up, all participants were invited to provide consent to be followed up 2 years later-ie, 3 years after randomisation. The primary outcome was pain-related physical activity limitation, self-reported via the Roland Morris Disability Questionnaire (0-24 scale) at 3 years. The secondary outcome was pain intensity at 3 years, assessed using the numeric pain rating scale. Adverse event…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 492 participants or records.
