Description of intervention(s) / exposure
The booster trial is designed to investigate the feasibility of developing a booster intervention. The goal of a booster intervention is to maintain any improvement in symptoms achieved as part of the primary trial.
The booster intervention will supplement the treatment provided as part of the RESOLVE trial.
The booster session will be delivered between 36-42 weeks from baseline of the RESOLVE trial. The session will last 30-60 minutes. It will be conducted in the same setting as the RESOLVE trial. The booster session will revisit the same treatment interventions introduced during the RESOLVE trial. No new content will be raised during the booster session.
The booster session will be tailored to each participant and could focus on any element of the RESOLVE trial.

The RESOLVE trial interventions include;
Discussion of the low back pain experience
- delivered over twelve weeks
Laterality recognition training
- delivered over eleven weeks
- involves distinguishing between images of trunks rotated to left or right using Recognise (NOIgroup) software package
Tactile acuity training
- delivered over ten weeks
- involves localising and/or discriminating between different types of non-noxious tactile stimuli or multiple simultaneous non-noxious tactile stimuli applied by the therapist to the lower back.
Motor Imagery
- delivered over ten weeks
- involves mental visualisation of movements of the lower back and lower limbs, with or without videos
Feedback enhanced functional movement training
- delivered over seven weeks
- involves graded, individualised training of functional movement patterns with mirror visual feedback

Discussion of the low back pain experience
- delivered over twelve weeks
Transcranial direct current stimulation (tDCS)
- delivered over eleven weeks
- involves application of tDCS whilst comfortably seated for 10-20mins
Cranial electrical stimulation
- delivered over eight weeks
- involves application of CES whilst comfortably seated for 30mins
Low-intensity laser therapy
- delivered over ten weeks
- involves application of low-intensity laser to the lower back whilst lying comfortably
Pulsed electromagnetic energy
- delivered over seven weeks
- involves application of pulsed electromagnetic energy to the lower back whilst lying comfortably

Where possible the same researcher who delivered the RESOLVE intervention will deliver the booster session to that participant. The researchers involved in delivering the RESOLVE intervention have physiotherapy or exercise physiology qualifications.

Participants allocated to the control arm of the booster trial will not receive a booster session. As part of the RESOLVE trial we will collect data on all participants at 18 weeks and 52 weeks post randomisation.

The researchers will follow a protocol for the intervention to ensure fidelity. The researcher will log data specific to the booster session to maintain fidelity such as time spent on booster session, perceived benefit of booster session.

Primary outcome [3] 319905 0
Feasibility of booster intervention- researcher time spent on booster session.
Measured as time in minutes with the participant.
Timepoint [3] 319905 0
The primary outcome for the RESOLVE trial will serve as the baseline outcome for the booster trial, which will be measured at 18 weeks post randomisation of the RESOLVE trial.

Secondary outcome [1] 369830 0
Feasibility of booster intervention- satisfaction with booster session
On a 0-10 scale, where 0 is not beneficial to 10 being very beneficial, how beneficial do you think this booster session was to you?
Timepoint [1] 369830 0
The primary outcome for the RESOLVE trial will serve as the baseline outcome for the booster trial, which will be measured at 18 weeks post randomisation of the RESOLVE trial.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The research assistant who determined if a subject was eligible for inclusion in the trial was unaware, when this decision was made, to which group the subject would be allocated.
Allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated using a computer generated number sequence, performed by a researcher not otherwise involved in either the Booster feasibility or RESOLVE trial.

Summary
Brief summary
Chronic low back pain (LBP), that is LBP that has persisted for longer than 3 months, is a growing health burden. One factor that contributes to the burden of low back pain is that the improvements in symptoms that effective treatments provide are not sustained over time. Effective treatments for LBP are becoming increasing complex. There is need to develop and test interventions aimed at maintaining the initial improvements from complex interventions.

One way to maintain improvements from complex interventions is by implementing booster interventions. The aim of a booster session is to maintain improvements in symptoms by reinforcing the training components of the intervention.

The RESOLVE will provide platform to test the feasibility of a booster intervention. The RESOLVE trial assesses the effectiveness of two complex treatment programs that combine central nervous system-directed and traditional interventions to promote recovery in participants with chronic LBP (the protocol is described elsewhere). One method to sustain any benefits achieved as a result of such a complex treatment intervention, such as in the RESOLVE trial, is to include a booster session.
