The main question it aims to answer is, if a behaviour change intervention and personalised physical activity prescription, are effective in improving the time spent in moderate to vigorous physical activity amongst chronic stroke survivors.

Researchers will compare the intervention group to a control group, to see if physical activity counselling and a personalized physical activity prescription is more effective in improving moderate to vigorous physical activity, than usual care alone. The study period for each participant is 6 months. Assessments are conducted at month 1 (baseline), 3 and 6.

The control group will receive only usual care, which consists of an information sheet on physical activity with the following content: (1) Why be active and (2) How to be active (with URL links to resources and videos). The usual care is delivered at 3-time points during month 1, 3 and 6.

The intervention group will receive usual care and a behavioral change intervention. The behavioral change intervention consists of up to 6 individual physical activity counselling sessions and a personalized physical activity prescription. The 6 sessions will take place only during months 1 to 3 and there will be no intervention during months 4 to 6. Of the 6 sessions, 3 are conducted face-to-face and another 3 sessions will take place using telehealth methods such as phone, text messaging and videoconference. Participants can meet the study physiotherapist at their preferred exercise space during the 3 face-to-face sessions. The physical activity counselling sessions consist of goal setting and action planning, and problem-solving barriers around participation in physical activity. The overall aim is to increase time spent in moderate-vigorous physical activity.

This trial will use a 1:1 concealed randomisation, to allocate participants with chronic stroke to an intervention group (n= 60) or control group (n = 60). Between-group comparisons will be made at 3 time points: months 1, 3 and 6.

The control group will receive usual care, which consists of 3 face-to-face sessions on general physical activity recommendations, lasting 30 to 60 minutes each during months 1, 3, and 6. Participants will be given an information sheet on the importance and benefits of physical activity after a stroke and general guidelines on how to start to be active. The general guidelines on how to be active include engaging in 150 minutes of moderate-intensity physical activity per week. The information sheet will also include links to publicly accessible online resources.

The intervention group will receive a behavioural change intervention, in addition to usual care. Information sheet about general guidelines on physical activity will be handed to the intervention group, as per control group. Each participant will receive up to 6 sessions of tailored behavioural change intervention during months 1 to 3 and there will be no intervention during months 4 to 6. Of the 6 sessions, 3 are face-to-face and another 3 will take place using telehealth methods such as phone, text messaging and videoconference. The tailoring of the intervention allows participants to decide the location during face-to-face sessions, how many sessions and how the sessions are spaced out during the 3-month intervention period and which sessions are face-to-face or telehealth. The preferred meeting location may include exercise spaces within home, common spaces just outside their homes and under their housing blocks, outdoor fitness zones or parks near home and residential or inclusive public gyms. The behavioural change intervention consists of physical activity counselling and prescription of a personalized physical activity plan. The first session will be conducted in-person, to allow the study physiotherapist to identify the participant's physical function, safety concerns and the impact of medical, social, environmental and resources on mobility. During the initial visit, the venue, frequency and mode of support (face-to-face or virtual) for subsequent sessions will be established. The study physiotherapist will provide physical activity counselling, set goals and discuss action plans to enhance moderate intensity physical activity, problem solve barriers on physical activity and prescribe a personalized physical activity plan. Subsequent sessions can include (1) training on physical activity modification to accommodate the weak arm and / leg at the participant's preferred exercise location, (2) taking videos of the personalized adapted exercises using the participant's phone when meeting face-to-face and (3) in-person or virtual support sessions to review physical activity progress and action plans.

A process and cost-utility evaluation will be embedded into the study design and conducted concurrently.
