Cognitive Functional Therapy (CFT) is a psychologically informed, physiotherapist-led intervention that targets the biopsychosocial complexity of persistent low back pain (LBP). CFT has demonstrated positive outcomes in two randomised controlled trials (RCT) but has not previously been evaluated in the United Kingdom National Health Service (NHS). This study aimed to determine the feasibility of completing a definitive RCT, that will evaluate the clinical and cost-effectiveness of CFT in comparison to usual physiotherapy care (UPC) for people with persistent LBP in the NHS. A two-arm parallel feasibility RCT compared CFT with UPC in participants with persistent LBP. Data concerning study processes, resources, management and patient reported outcome measures (disability, pain intensity, quality of life and psychosocial function) were collected at baseline, three and six-month follow-up, analysed and evaluated in order to establish feasibility. Sixty participants (n=30 CFT and n=30 UPC) were recruited with 71.6% (n=43) retained at six-month follow-up. CFT was delivered to fidelity, relevant and clinically important outcome data were rigorously collected and CFT was tolerated by participants with no safety concerns. The Roland-Morris disability questionnaire was the most suitable primary outcome measure and sample size calculations were completed for a definitive RCT. Intention to treat analysis indicated a signal of effect in favour of CFT with moderate and large between group effect sizes observed across outcome measures at six-month follow-up.Purposes of the study and background
Methods and results
Cognitive Functional Therapy (CFT) is a complex intervention that targets the biopsychosocial nature of low back pain (LBP). The barriers and facilitators to CFT have not previously been researched in the United Kingdom National Health Service (NHS). This study aimed to explore the barriers and facilitators of CFT in the NHS ahead of a future clinical trial. Participants who had completed a CFT intervention for persistent LBP and physiotherapists who had previously attended a CFT training workshop were recruited. Data were collected using one to one semi-structured interviews and were analysed thematically using framework method. Eight people with LBP and ten physiotherapists consented to participate. The key findings were that UK NHS physiotherapists can be trained to deliver CFT, they valued the training and felt confident to deliver CFT successfully to patients in NHS physiotherapy departments. Peer support and mentorship from a CFT practitioner was necessary for the physiotherapists to sustain changes to their clinical practice. Participants with LBP welcomed CFT as they felt it was beneficial and enabled them to self-manage their LBP and they could recognise the difference between CFT and usual care. The barriers, mainly related to the healthcare system, included short appointment times and poor availability of follow-up appointments.Purposes of the study and background
Methods and results
Traditional physiotherapy methods utilised in the management of NSCLBP have small effects on pain and disability and this is reflected by data previously collected by the host physiotherapy service. O'Sullivan has validated a novel classification system and matching treatment strategy known as Classification Based–Cognitive Functional Therapy (CB-CFT) for people with NSCLBP. Briefly, CB-CFT is a behavioural and functional management approach to NSCLBP. A recent RCT employing CB-CFT has demonstrated superior outcomes in comparison to traditional physiotherapy methods advocated by clinical practice guidelines. It was unknown if CB-CFT improved outcomes for people with NSCLBP attending an NHS physiotherapy service, therefore an evaluation of practice was proposed. People referred to physiotherapy with NSCLBP were assessed and treated by a physiotherapist trained in the delivery of CB-CFT. Primary outcomes of interest included the Oswestry Disability Index (ODI) and Numerical Pain Rating Scale (NPRS). A retrospective evaluation was performed for sixty-one people referred to physiotherapy with NSCLBP. Statistically significant improvements in disability (ODI p<0.001) and pain (NPRS p<0.001) were demonstrated. 88% of people achieved minimum clinically important change, defined as >10 points for the ODI and 75% of people achieved minimum clinically important change, defined as >2 on NPRS. Mean improvement of 24.7 points for the ODI and 3.0 for NPRS was observed immediately following CB-CFT, demonstrating large effect sizes of 1.56 and 1.21 respectively.Purpose and Background
