Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The telehealth breathing training group consists of 6 sessions over an 8-week period delivered via ZOOM or PEXIP (videoconferencing platform for NSW Health). Each breathing intervention group will have a minimum of 4 participants and no more than 8 participants to ensure individualised feedback is provided. All breathing intervention groups will receive the same intervention program. Each session will be co-run by the principal researcher and one of the associate researchers when feasible. Sessions will be 45 to 60 minutes each in duration. The breathing intervention consists of education focusing on the relationship between breathing, chronic pain, and the autonomic nervous system. Breathing intervention will consist of practicing diaphragmatic breathing and exploring a range of breathing patterns. Participants will engage in group breathing practice and receive feedback for their techniques. Home practice materials in the form of written materials will be made available to the patients at the end of each session. These home practice materials about the breathing techniques and patterns discussed will be designed specifically for this study. Participants will be expected to perform home practice at least 5 days a week. The duration will be at the participant's discretion but recommended to be more than 10 minutes each time. Participant's adherence to the intervention will be monitored via the use of session attendance sheet, and discussion about home practice at each session when appropriate.

Treatment: Other
Comparator / control treatment
Standard care.

The control group will continue with standardized care, consisting of scheduled appointments with chronic pain services team, primary health care and pharmacological intervention. At the end of the clinical trial, participants will be offered the breathing intervention if it was found to be beneficial. These participants will not be followed up after they start the intervention.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization by computer using central randomization by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer-generated randomization will be performed using a random number generator via an Excel spreadsheet. The randomization process will be undertaken by a research team member who will not be involved in the participant recruitment process directly.

Statistical methods / analysis
All quantitative data in this study will be analysed using the Statistical Package for the Social Sciences ver. 28.0 (SPSS Inc., NY, USA). The Shapiro-Wilk test and residual plot assessment will be used to check for normality prior to analyses. Analyses will be carried out on intention-to-treat basis. The reported outcomes for each standardised measure will be reported as the mean and standard deviation through descriptive statistics, or non-parametric equivalent for data that do not meet normality criteria. A mixed model approach will be used to account for the repeated measures and a participant’s baseline values. Between-group differences will be reported as estimated marginal means from Bonferroni-adjusted post-hoc tests. The primary outcome measure is DASS 21 and the secondary outcome measures are BPI, NRS, PSEQ, PCS and MSK-HQ. The differences in each outcome measures between follow-up and pre-intervention will be presented as mean difference and 95% confidence intervals. A parametric test comparing the 3-time points within and between groups will be used. A significant level will be set at p < 0.05 for all tests.
