Description of intervention(s) / exposure
Both groups will receive a 12-14 week multi-disciplinary pain management program aiming to improve quality of life through a goal oriented graded activity/exercise program provided by registered medical, physiotherapy, psychology and dietitian practitioners with a special interest in chronic pain. There will be approximately 12 individual psychology sessions (1 hour each), 16 group psychology sessions (2 x 60 minutes per week over the final 8 weeks), 32 x 45 minute individual physiotherapy sessions, 4 x 60 minute group dietitian sessions ± 4 x 30 minute individual dietitian sessions (if indicated), >4 x 30 minute individual medical sessions over 12 weeks. Group sessions would have no more than 10 participants. The program may be delivered face to face or via telehealth based on participant preference. Each session in both groups will focus on goal setting and scheduling activities and exercises that enable achievement of short, medium and long term goals. Common goals and associated activities would include hobbies (eg playing local football), relationships (eg communicating positively with partner over dinner) and work (eg returning to normal duties/hours). Common exercises between groups include walking and standing functional exercises (eg bicep curls, front raises, squats, step ups). Biological, psychological and social barriers to achieving goals would be addressed through education and a cognitive behavioural approach. Adherence would be checked through electronic records of completed sessions as well as goal/rehabilitation sheet analysis tracking daily activity/exercise/goal achievement. Following discharge from the program there would be low frequency (typically monthly for 6 sessions) physiotherapy ± psychology/medical sessions up to 52 weeks to support achievement of long term goals. Both groups will receive treatment based on the participant's goals and the barriers to recovery identified by the practitioners.

The difference between the groups relates to the approach used in the physiotherapy sessions (both in the 12 week program and in sessions up to 52 weeks) whereby the intervention group will include the provision of specific training to optimise posture, movement and muscle activation in low load positions, prior to commencement of upright functional exercises) and subsequently integrated in daily activities (Hodges 2013). The exercises chosen as part of the MInS intervention will depend on the patient's presenting problems and functional task goals, and will be chosen by the individual therapist after a structured and detailed assessment of posture, movement and muscle activation while completing various functional tasks. There is no standard set of exercises for practitioners to choose from in the MInS intervention, and the dosages will vary based on the results of the detailed assessment of posture, movement and muscle activation (ie. this cannot be outlined a priori given it is individualised). The number and length of physiotherapy sessions will be similar between groups (as outline above), with the MInS treatment integrated within those standard sessions. Intervention (MInS) group practitioners will be trained before the trial commences according to a specific clinical protocol including assessment of competency prior to providing treatment to intervention group participants.

Comparator / control treatment
Standard multidisciplinary pain management, defined as a 12-14 week multi-disciplinary pain management program aiming to improve quality of life through a goal oriented graded activity/exercise program provided by registered medical, physiotherapy, psychology and dietitian practitioners with a special interest in chronic pain. There will be approximately 12 individual psychology sessions (1 hour each), 16 group psychology sessions (2 x 60 minutes per week over the final 8 weeks), 32 x 45 minute individual physiotherapy sessions, 4 x 60 minute group dietitian sessions ± 4 x 30 minute individual dietitian sessions (if indicated), >4 x 30 minute individual medical sessions over 12 weeks. Group sessions would have no more than 10 participants. The program may be delivered face to face or via telehealth based on participant preference. Each session will focus on goal setting and scheduling activities and exercises that enable achievement of short, medium and long term goals. Common goals and associated activities would include hobbies (eg playing local football), relationships (eg communicating positively with partner over dinner) and work (eg returning to normal duties/hours). Common exercises between groups include walking and standing functional exercises (eg bicep curls, front raises, squats, step ups). Biological, psychological and social barriers to achieving goals would be addressed through education and a cognitive behavioural approach. Adherence would be checked through electronic records of completed sessions as well as goal/rehabilitation sheet analysis tracking daily activity/exercise/goal achievement. Following discharge from the program there would be low frequency (typically monthly for 6 sessions) physiotherapy ± psychology/medical sessions up to 52 weeks to support achievement of long term goals. Both groups will receive treatment based on the participant's goals and the barriers to recovery identified by the practitioners. The control group will not receive specific exercises or training related to their posture, movement and muscle activation prior to the commencement of common functional restoration exercises, instead only completing the common exercises above related to functional restoration. The number and length of physiotherapy sessions will be similar between groups.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To enrol a participant, after baseline assessment, the treatment centre will email the consenting participant’s name and date of birth to an offsite randomisation service. This service will have no contact with trial participants. They will allocate the participant to a treatment group in accordance with the randomisaton schedule and advise the treatment centre of the allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation schedule for allocating participants to either of the groups will be prepared in advance by an offsite researcher not involved in assessing, enrolling or treating the participants. Block randomisation (with random block lengths), with stratification for treatment centre (7 levels) will be employed.

Efficacy
Statistical methods / analysis
Data analysis will focus on detecting the between-group treatment effects at each follow-up. Analyses will be conducted using SPSS, with alpha set at 0.05 using a two-tailed hypothesis. Continuous data will be analysed using linear mixed models (with the group x time interaction estimating the treatment effect), adjusting for baseline scores and the stratification variables (treatment centre). Ordinal data will be analysed using the Mann Whitney U test.

All data will be analysed on an intention to treat basis. A within-trial cost-effectiveness analysis will be undertaken based on the EuroQol 5-D and healthcare utilisation data from the participant diary.

Treatment moderator analysis: The following factors will be evaluated for their ability to moderate the effects of treatment on the primary outcome:
1. Dominant pain type (neuropathic or nociceptive)
2. Positive response to correction of unhelpful motor control characteristics at baseline assessment

Mediation analysis: the sample is sufficient for detecting moderate or large mediation effects. The following variables will be explored for their ability to mediate the effects of treatment on the primary outcome:

1. Changes in motor control characteristics chosen as relevant by the therapist for each individual on physical examination

If pre-planned effect modifier and mediation hypotheses do not result in statistically significant results, a data-driven approach will be employed to identify new hypotheses.
