Interventional
Description of intervention(s) / exposure
This study aims to assess whether a remotely supervised home-based minimal equipment exercise training program is a feasible and acceptable model of pulmonary rehabilitation for people with chronic respiratory disease.

Home-based minimal equipment exercise training program involves twice-weekly sessions for 8 weeks, in groups of 2-4 participants at a time. The sessions are remotely supervised by an experienced exercise physiologist or physiotherapist (via video-conferencing), participants will be able to interact via video-conferencing technology with other group participants and the supervising clinician. Each session, participants will undertake circuit-based training incorporating 7 exercises. Exercises included in the program are sit to stand, air boxing, step up, step to side with lateral raise, bent over row. The total training session duration will be 45minutes; each exercise circuit will be between 15-16minutes in duration (including interval rests) and repeated 3 times, accounting for a total exercise time of 31.5minutes. A 5minute rest period will be undertaken between each circuit.

Intensity
Moderate-intensity exercise training will be prescribed and progressed according to guidelines, Borg dyspnoea score 3-4 correlating to the equivalent of work rate greater than or equal to 60% VO2peak (Mellerick et al. unpublished). Exercise will be progressed each week to ensure time and load correlate to Borg dyspnoea scores of 3-4 (Gloeckl R et al. Eur Resp Rev, 2013). If unable to progress time due to fatigue or endurance issues, load may be progressed first.

Participants ratings of perceived exertion and breathlessness, heart rate and oxygen saturation will be monitored throughout the sessions. Heart rate and oxygen saturation will be measured via an ear probe pulse oximeter worn in a Nonin oximeter bag with cross body strap.
All equipment required to undertake the tele-rehabilitation will be supplied by the study investigators for the duration of the rehabilitation period.

Home Visit
An initial home visit will be completed by an experienced clinician prior to program commencement. The home visit will involve delivery of the intervention kit including equipment and iPad, setting up the exercise circuit and a familiarisation session to ensure appropriate exercise and videoconferencing set-up. The participant will be provided with a participant exercise booklet and instruction manual to assist with videoconferencing set-up and troubleshooting issues. To ensure the safety of the healthcare professional during home visits, the relevant institution Home Visit Assessment Policy will be adhered to as per standard practice. We have previously completed trials involving these processes in delivering telerehabilitation with no risk or harm to participants or clinicians.

Treatment: Other
Comparator / control treatment
The control group will receive traditional outpatient centre-based pulmonary rehabilitation program. Traditional outpatient centre-based pulmonary rehabilitation utilises specialised equipment such as treadmills, cycle ergometers and specialised resistance equipment. This involves twice-weekly exercise training sessions for 8 weeks, in directly supervised groups of 8-12 participants. Program is delivered by an experienced exercise physiologist or physiotherapist. Each session, participants will undertake continuous aerobic exercise for a total of 30minutes on a cycle ergometer or treadmill and complete upper and lower limb resistance training. Aerobic training will be individually prescribed and progressed according to a standardised protocol utilising Borg dyspnoea scores 3-4 (Gloeckl R et al. Eur Resp Rev, 2013). For resistance training, this will comprise of both upper and lower limb strength training exercises including exercises such as; sit to stand, upright row, step up.
Exercise will be progressed each week to ensure intensity correlates to Borg dyspnoea scores of 3-4 (Gloeckl R et al. Eur Resp Rev, 2013), (Cox NS et al. Thorax, 2022).

Eligibility
Key inclusion criteria
This study will include people aged 18 years and over with a confirmed diagnosis of chronic respiratory disease who are referred to pulmonary rehabilitation at Alfred Health, VIC, Melbourne.

Minimum age
18 Years
Maximum age
No limit

Key exclusion criteria
Potential participants will be excluded from this study if they have:

Efficacy
Statistical methods / analysis
Sample size was estimated to evaluate the primary outcomes of feasibility and acceptability of the exercise intervention, based on guidance from previous literature (Paixao C et al. Heart Lung. 2023), (Lewis A et al. BMJ Open Respir Res. 2021), (Cox NS et al. Respir Care. 2015), (Khor YH et al. Sci Rep. 2021), (Eldridge SM et al. CONSORT. 2016)

No formal power calculation is required as this is a feasibility trial. We will aim to recruit a total of 30 participants, as this will be sufficient to capture a representative range of age, diagnosis and comorbidities. The trial will not be powered to identify change in the secondary outcomes; however, outcome data may be used to inform sample size calculation for a larger trial.

Descriptive statistics will be employed for quantitative data, using n (%) for categorical data and mean (SD) or median (interquartile range) depending on distribution for continuous data. Between-group differences will be assessed using chi2 test for categorical data and 2-sided tests (parametric or non-parametric depending on data distribution) will be used for continuous data (a<0.05).

Qualitative data - interview transcripts
All de-identified transcripts of the interviews will be analysed by two researchers independently. Descriptive codes will be generated to represent the data. Related codes will be collapsed into defining subthemes, ideas or categories. Data will then be identified into broader themes and categories for interpretation and linking back to the research questions.
