E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to explore the feasibility of running a randomised controlled trial to test the hypothesis that for people with suspected facet joint pain contributing to persistent low back pain, adding the option of facet joint injections to best usual non-invasive care available from the NHS is clinically and cost effective. |
|
E.2.2 | Secondary objectives of the trial |
• To develop, and evaluate, agreed criteria for identifying people with suspected facet joint pain. • To develop an agreed protocol for the injection of facet joints in a consistent manner. • To develop, and evaluate a standardised control treatment deliverable in the NHS and congruent with NICE guidance (best usual care). • To develop and test systems for collecting short term and long-pain outcomes, including measures required for economic evaluation. • To demonstrate that recruitment to the main trial is feasible. • To collect the recruitment and outcome data required to inform sample size and number of sites needed for the main trial. • To conduct a between group analysis to inform decision on the need for a full trial. • To do a process evaluation of patient experience within the trial data from exploratory work, data from pilot trial, data from both exploratory work and pilot trial.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients may be included in the trial if they meet all of the following criteria:
1. The patient is able and willing to comply with the trial procedures and signed and dated informed consent is obtained. 2. The patient is >18 with at least moderately troublesome low back pain present for at least six months. 3. The patient's low back pain is their predominant musculoskeletal pain. 4. The patient has undergone therapist-delivered treatment for low back pain in the preceding six months prior to inclusion. 5. The patient meets clinical criteria for possible facet joint pain when there is no radicular symptoms (defined as pain radiating below the knee) and no sacro-iliac joint pain elicited using a pain provocation test and increased pain unilaterally, bilaterally on lumbar para-spinal palpation, and increased low back pain on one or more of the following; extension (more than flexion), rotation, extension/side flexion, extension/rotation. 6. The patient is able to manage text messaging, or an alternative means of daily data collection (paper based diary). 7. The patient is fluent in written and spoken English.

|
E.4 | Principal exclusion criteria |
Patients must be excluded from participating in this trial if they meet any of the following criteria: 1. The patient is unable to attend for randomised treatment, or other circumstances that would significantly decrease the chance of obtaining reliable data, achieving trial objectives or completing the trial and follow up assessments or is considered unsuitable to participate in the trial by an investigator. 2. The patient is unable/unwilling to undergo injections. 3. The patient has used corticosteroids or had a corticosteroid injection in the preceding three months. 4. The patient has an underlying serious psychiatric or psychological disorder that precludes participation in either intervention. 5. The patient has previously undergone spinal injections. 6. The patient has previously undergone spinal surgery 7. The patient has a contraindication to facet joint injections for example a serious co-morbidity (eg severe COPD, poorly controlled diabetes) malignancy, infection, inflammatory disorder, or fracture or is taking anti-coagulant medications. 8. The patient has a known allergy to the constituents of the planned injections. 9. Pregnancy. We will follow Royal College of Radiologists Guidance on radiation and the early fetus. (http://www.rcr.ac.uk/docs/radiology/pdf/BFCR(13)4_radiation.pdf) We will ask women of child bearing potential if they might be pregnant when they are assessed for study assessment. For those randomised to injections we will follow local policy for assessing any risk to an early fetus before exposure to radiation. Where appropriate we will arrange to schedule injections within ten days of the onset of menstruation. 10. The patient was previously randomised in this trial. 11.The patient is currently participating in another clinical trial (with an unregistered medicinal product), or less than 90 days have passed since completing participation in such a trial.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome for this feasibility trial is numerical rating scale for pain collected via text messaging (or paper) over three months following randomisation. As a second primary outcome focused on back pain related disability we will use the Roland Morris Disability Questionnaire at three, six and 12 months collected using a postal questionnaire. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Daily pain score for a period of 35 days starting seven days before first physiotherapy treatment after which weekly scores will be collected until the 3-month enpoint is reached (via text messaging or paper). The Roland Morris Disability Questionnaire will be given at three, six and 12 months and collected using a postal questionnaire. |
|
E.5.2 | Secondary end point(s) |
In addition to the primary endpoints there are a number of secondary endpoints these relate to life with back pain and include: health utility (EQ5D), pain self-efficacy, Warwick Edinburgh mental wellbeing scale (WEMWEBS), Depression Anxiety and Positive Outlook Scale (DAPOS), satisfaction with health state, patient generated index, back pain troublesomeness and quality of life (SF-12). These measures like the primary measures will be collected at baseline, three, six and twelve months. In addition, health utility information (EQ5D) will be collected weekly from first physiotherapy treatment session until night before injection appointment when daily for eight days; then back to weekly until the three months endpoint. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Health utility information (EQ5D) will be collected weekly from first physiotherapy treatment session until night before injection appointment when daily for eight days; then back to weekly until the endpoint (3 months) participants will provide these ratings on daily diary sheets. Baseline questionnaires will be completed at the time of enrolment and follow-ups will be at three, six and twelve months will be via postal questionnaires.
