Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A physiotherapist with 15 years’ experience will deliver 60-minute exercise classes once a week, over 12 weeks, at the University of South Australia, East Campus. The maximum 3 people face-to-face groups will receive some weekly individual tailoring (progression/regression) by the physiotherapist relative to participant capacity. Checklists will record weekly attendance and exercise modifications. Exercises will address mobility (eg. pelvic tilts/clocks, book openings), stability (eg. bridging, plank) and whole-body integration (eg. rolling side to side, variations of getting on/off the floor). The intervention group will combine 60 minutes of standardised floor exercises with the addition of specific cues throughout the session. Intensity will be low to moderate, with participants able to talk comfortably throughout the session.

Rehabilitation
Comparator / control treatment
The control group receives the same standardised floor exercises, length of session, location and class size as the intervention group, focusing on completion of the exercises. Specific cues in the intervention group will be omitted for the control group. Intensity will be low to moderate, with participants able to talk comfortably throughout the session.

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)
Allocation will be computer generated and administered via phone to the physiotherapist conducting the intervention
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation). A person independent to the intervention/assessment will generate the groups.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s

Efficacy
Statistical methods / analysis
The mixed-methods feasibility trial will recruit approximately 24 participants. The small sample size will require baseline characteristics and feasibility outcomes to undergo descriptive analysis. Calculations of feasibility outcome measures and exploratory analysis, using inferential statistics of remaining outcome measures, will inform future sample size requirements.

Summary
Brief summary
The feasibility pilot trial will recruit and randomly allocate approximately 24 adults with lower back pain to an exercise program with or without breathing cues. The 12 x 1-hour exercise sessions will be weekly for 12 weeks at University of South Australia East Campus. Some individual tailoring (progression/regression) for individual capacity will be undertaken and recorded by the physiotherapist. The intervention and control groups will experience the same standardised floor exercises, length of session, location and class numbers. The aim is to determine if the addition of specific cues to a 12-week exercise program alters participant tolerance and compliance, including dropout rate and satisfaction. The aim is not to establish evidence reliant on sample size, rather determining which measures demonstrate most relevance for future research.
