Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There will be three phases for the single group, comorbidity-adapted exercise program (intervention): diagnostic, development and intervention phases.

Diagnostic phase: At Macquarie University, a primary health care practitioner (PHCP) will obtain a thorough medical history, and then perform a physical and functional examination to determine contraindications and restrictions to an exercise program. This is expected to take 45 minutes.

Development phase: In the first exercise program session, anticipated to be 60 minutes duration and will be held at Macquarie University, the PHCP will design and tailor the session to adapt the exercise program to the older individual, and provide patient education. The exercise program will be consist of lower extremity and back extensor muscle-strength training, aerobic training, core stability exercises, balance training and lower limb and back stretching based on an inventory. Adapting the exercise program for individual patients will include tailoring the exercise frequency, intensity, timing, and exercise type based on the presenting comorbid condition(s). At this session the PHCPs will provide patient education, explore the participant’s goals, motivations and barriers to an exercise program and provide the participant with paper-based GLA:D Back pain education material.

Intervention phase: The exercise program will consist of 16 sessions throughout the eight-week exercise program. There will be two PCHP supervised sessions per week with each session being approximately 60 minutes in duration. Exercise program sessions will be provided in a group exercise session, at Macquarie University. The Borg Rate of Perceived Exertion scale will be used to monitor training intensity during each supervised exercise program session, and it is expected that exercise programs sessions will be of low to moderate intensity. Educational and coaching strategies will supplement the comorbidity-adapted exercise program throughout each supervised session, with adaptation to the exercise program patient directed. Attendance will be recorded at each exercise session throughout the study and adherence to the exercise program will be assessed using an exercise diary to document the proportion of available sessions attended, the completion of each session, whether participants could complete each component of the exercise program (i.e duration and/or repetitions) and whether participants could complete the full duration of the exercise program. After their last session, participants will be interviewed by the research assistant to explore the feasibility of the exercise program and barriers and facilitators to their participation.

Adverse events are defined as any undesirable experience occurring during the study (regardless of whether this was related to the treatment), by the participant and will be reported by both the participant and PCHP. Adverse events or discomfort experienced by participants during this study may relate to possible side effects from performing the exercise program. During the administration of the exercise program, should a severe exacerbation of a comorbid condition arise, an ambulance will be called, and the event will be documented in the patient’s file. There is also the possibility of uncovering an unexpected medical condition during the diagnostic phase of the exercise program. Should this arise, the participant will be referred to their general medical practitioner with a letter stating the relevant findings.

Statistical methods / analysis
The analysis will include both a descriptive analysis and qualitative evaluation. The primary outcome is to assess the feasibility of the comorbidity-adapted exercise program for older adults with low back pain and comorbid conditions. We will do this via an evaluation based of progression criteria such as trial recruitment, protocol adherence and outcome data. Mean outcome measures change scores will be calculated by subtracting the post-exercise program scores (eight weeks) from baseline scores, with standard deviation (SD) and 95% Confidence Intervals (CI) reported. All semi-structured interviews will be electronically recorded, transcribed, and imported into the NVivo data management programme (NVivo qualitative data analysis software; QSR International Pty Ltd). Transcripts will be coded to the domains of the Theoretical Domains Framework to extract the acceptability, barriers and facilitators of the exercise program. Transcripts will be coded systematically and iteratively until saturation is achieved. PCHP diaries will be reviewed to identify barriers to inform future trials.

Summary
Brief summary
Low back pain is common, with the prevalence of low back pain increasing across the lifespan where it has a profound impact on physical and psychosocial health. Also, with increasing age comes increasing comorbidity and this also has pronounced health consequences. While exercise is beneficial for a range of health conditions, trials of low back pain and exercise often exclude older adults. This mixed methods study will assess the feasibility of an eight-week comorbidity-adapted exercise program for older people with low back pain and comorbid conditions.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
This is a small (n=24), mixed methods study to test the feasibility of an exercise intervention for older adults with low back pain. Health outcome data are not the primary outcome of the study, and therefore we do not see that IPD is relevant for future sharing.
