Design outcomes

Primary

MeasureTime frame
All participants will be assessed at baseline (week 0), 3 months (week 12), and 9 months (week 36). Safety: 1. Fatigue is assessed using the Modified Fatigue Impact Scale 2. Pain is assessed using the question regarding pain on the EQ-5D-5L 3. Number and type of adverse events and serious adverse events including falls and relapses throughout the duration of the participants' involvement in the trial (9 months). Participants will specifically asked if they have experienced a fall, relapse or other adverse event since their last contact with the research team at each assessment point (week 12 and week 36). Feasibility and acceptability 1. Attendance of participants at each intervention session 2. Completion of the handbook and diaries 3. Fidelity to the intervention using audio-recordings of 10% of each session (i.e. 1, 2, 3, and 4) for each therapist 4. Physiotherapist reported experience of delivering the intervention through semi-structured interviews 5. Participant reported experience of receiving the intervention through semi-structured interviews with 15 participants purposively sampled from the intervention group Feasibility of conducting a definitive trial: 1. Monitoring recruitment and retention rates 2. Identifying reasons for non-participation using a questionnaire distributed to people who refused to participate in the trial 3. Determining the feasibility and acceptability of randomisation by interviewing a random selection of 10 participants in the control group 4. Monitoring the completion rate of outcome measures relating to the effectiveness of the trial

Secondary

MeasureTime frame
The following outcomes will be assessed in all participants at baseline (week 0), 3 months (week 12), and 9 months (week 36). These outcomes are the proposed outcomes that will be used to determine the effectiveness of the intervention if a definitive trial is conducted. 1. Light, moderate and vigorous physical activity assessed by the Actigraph GT3x+ accelerometer 2. Sedentary behaviour assessed by ActivPAL3µ activity monitor 3. Self-reported physical activity and sedentary behaviour assessed by the International Physical Activity Questionnaire short-form 4. Fatigue assessed by the Modified Fatigue Impact Scale 5. Walking capability assessed by the Twelve Item MS Walking Scale 6. Self-efficacy assessed by the Multiple Sclerosis Self-Efficacy Scale 7. Quality of life as assessed by the EQ-5D-5L 8. Health service use assessed by the Adapted Client Service Receipt Inventory 9. Participation assessed by the Impact on Participation and Autonomy Questionnaire
