Table 3 Overview of the feasibility evaluation of the mHealth version of the i-REBOUND programme

Reach

 Study recruitment

Proportion of individuals post stroke or TIA screened and deemed eligible for the trial and the proportion of those consenting which are randomised to the trial. Number of study participants requiring assistance to download or access the STAAR app.

Collected by the research team during the recruitment procedures.

 Representativeness

Study sample demographics contrasted to national data of the targeted population [13].

Collected by the research team during screening for eligibility and through digital questionnaires administered at baseline.

Adherence

 Drop-outs

Number of participants not completing the trial and reasons for withdrawal.

Collected by the research team from point of inclusion until 12-month follow up.

 Assessment protocol

Proportion of missing data for clinical outcomes used to assess blood pressure, physical activity, exercise self-efficacy, fatigue, psychosocial wellbeing and health related quality of life.

All clinical outcomes will be self-reported by the participants in the STAAR app at each assessment time point, except for physical activity which will be measured using an activity monitor.

Safety

 Adverse events

Number and type of adverse events (including, but not limited to, falls, increase in pain, or hospitalisation).

Reported by either the participants or physiotherapists during the 6-month intervention and recorded by the physiotherapist in the digital clinic.

Fidelity

 Supervised exercise

Number of supervised exercise sessions (individual or group) attended with reasons for non-attendance where applicable. Supervised exercise intensity and progression (i.e., changes in the supervised exercise level).

Reported by the physiotherapists in the digital clinic after each supervised exercise session. The Borg RPE scale will be used to assess exercise intensity.

 Prescribed exercise

Number of study participants who have been prescribed exercises and prescribed exercise dose (i.e., number of exercises and repetitions).

Information registered automatically in the digital clinic at point of prescription by the physiotherapist.

 Behaviour change techniques

Number of study participants taking part in individual counselling and structured follow-ups. Number of goals, goal characteristics, and goal fulfilment across the intervention period.

Recorded by the physiotherapist in the digital clinic after each individual counselling and follow-up session.

 Technology usage

Number of times the STAAR app is accessed by study participant and the purpose of accessing (e.g., exercise programme, educational videos and self-monitoring). Number of technical problems including inability to connect to the STAAR app or attending meeting with physiotherapist.

STAAR app access recorded automatically in the digital clinic. Technical problems reported by both participants and physiotherapists to the research team.
