Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The previous Chest, Heart and Stroke, Scotland (CHSS) funded pilot study demonstrated that community dwelling stroke survivors are significantly less physically active and spend significantly more time sedentary compared to healthy, matched controls. (Paul et al. 2015). The investigators have also reported that using the STARFISH smartphone app (described below) for six weeks had a positive effect on physical activity These pilot results support the development of a fully powered, randomised controlled trial.
Starfish description Research team members have developed STARFISH, a smartphone app, which aims to encourage users to become more physically active. The sensors within a standard smartphone record the number of steps taken per day by the individual.
STARFISH is undertaken in groups of four to facilitate social support and each group member receives a personalised daily step count target. Each person is represented by coloured fish, and participants can see their own and other group members' fish in a fish tank on their smartphone. When the participant is walking, their fish swims and blows bubbles and, as participants progress towards their daily step count target, their fish's fins and tail grow. When all group members reach their target on five days of the week, the group is rewarded by another sea creature appearing in their fish tank (e.g. a seahorse).
Aims and Objectives
The primary objective of the study is:
To compare objectively measured physical activity in community dwelling stroke survivors who have undertaken a four month physical activity intervention using the STARFISH application with a control group receiving four months of usual care.
The secondary objectives are:
1. To compare objectively measured sedentary time, activity profiles, walking endurance, walking speed, activities of daily living (ADL), fatigue, anxiety and depression, quality of life and metabolic health-risk biomarkers in community dwelling stroke survivors who have undertaken a four month physical activity intervention using the STARFISH application with a control group receiving four months of usual care.
2. To determine if the effects of the STARFISH intervention are evident two months after completion of the intervention.
Design and Methods The design is a single blind, parallel randomised control trial (RCT). An assessor, who will be blinded to the group allocation will perform the outcome measures.
Methods Participants Using pilot study data the investigators estimated that the RCT will need 58 subjects in each group to detect, with 80% power a 30% increase in step count, between intervention and control groups, at a 5% level of significance. Therefore to allow for some drop out, 128 people who fulfil the inclusion and exclusion criteria, and who give written informed consent will be recruited to the study.
Participants will be recruited through a number of routes:
* through Chest Heart \& Stroke (CHSS) affiliated groups in the West of Scotland
* in NHS Lanarkshire through the stroke liaison nurses who will identify appropriate patients from stroke audit system and through the Lifestyle Group .
* in NHS Ayrshire and Arran through the physiotherapists and stroke liaison nurses
* in NHS GG\&C through the Community Stroke Team Participants identified in any one of routes described above will be given a Participant Information Sheet (PIS), from the clinician or CHSS group co-ordinator. In NHS Lanarkshire potential participants identified from the database will be sent a letter and PIS from the Lead Stroke Clinician. Those interested in taking part in the study will be asked to contact the researcher using the contact details on the PIS.
Following discussion with the researcher those willing to take part will be invited to attend Glasgow Royal Infirmary (GRI) clinical research facility, NHS Lanarkshire clinical research facility and NHS Ayrshire \& Arran clinical research facility . At the initial visit the participant will meet both researcher and assessor. In order to keep assessor blind to the group allocation the researcher and the assessor will see participants separately in different rooms.
Participants will see the researcher first, where they will have the opportunity to ask further questions, if they then agree to taking part in the study they will be asked to sign a consent form. Consent will also be sought to contact participant's GPs to inform them of their participation in the research study. For participants recruited from CHSS groups their GPs agreement will be sought for their participation in this study. All participants will be informed that they are free to withdraw from the study at any time.
Those who provide their informed consent will then be directed to the assessor to undergo baseline measures. All baseline measures will be made prior to group allocation, Participants will then be directed to see the researcher who will randomise them to one of the groups. The patients will be recruited in groups of 8. For the randomisation process a list of random numbers will be generated using an Excel spreadsheet. Each number will then be printed out and placed in identical, opaque envelopes, even numbers represent the Intervention group and odd numbers the Control group. Participants will be given consecutive envelopes as they are recruited so that two groups of 4 participants will be formed with each randomisation stage.
The Intervention Group:
The intervention is a four month physical activity intervention using the STARFISH app with the aim of increasing the participant's number of steps above their baseline value. Participants allocated to the intervention group will be given a mobile phone and asked to carry the phone for seven days to establish their normal level of physical activity (PA). They will work in groups of four (as explained above) but each participant will have their own individualised step count target. The initial step count target will be created by adding 10% to the mean number of steps per day recorded on the phone. At the end of each week, step counts will be reviewed from the data on the server. If the participant reaches their step count target on at least five days of the week, then their target will be increased remotely by 5% for the following week, up to a maximum increase of 3000 steps above baseline (Fitzsimons et al. 2008). Where a participant fails to reach their step count target, it remains unchanged for the following week. Participants will be notified about their step count target change via a message displayed on their smartphone screen.
Each intervention group will meet, as a group of four participants, seven days after their baseline assessment. At this visit the researcher will explain STARFISH app and provide participants with an instruction manual to refer to if needed. Initial step count targets will be calculated (as described above), agreed with participants and set. The Intervention group will then meet with the researcher 2 months later to discuss their progress, ask any questions or raise any concerns. The researcher will meet the intervention group at the end of the programme, before their second assessment (at 4 months) to collect their smartphones. At this visit a focus group, with the STARFISH group of four participants, will be undertaken to explore participants' views of the acceptability and usability of STARFISH app.
During the intervention period participants will be given contact numbers of the researcher to call if they experience any problems.
The Control Group:
Participants allocated to the control group will be given a booklet with general advice on physical activity.
All participants will be sent a lay summary of the study at the end. Outcome measures will be taken at baseline, 4 months (end of the intervention, primary end point) and 6 months (two months after the intervention).
Descriptive statistics will be used to summarise all variables at each time point. Group differences and interaction effects for each variable will be assessed using a two-factor repeated measures ANOVA model with a Greehosue-Geisser correction factor. Model assumptions will be checked and if required appropriate transformation will be used. Where a significant Time effect is found Tukey's post hoc test will be used. Effect sizes will be reported as will estimates of observed power. All analysis will be performed on IBM SPSS v22 and the level of significance will be set at 5%.
