Official title:
The Effectiveness of Video Guided Exercise After Stroke
People who have had a stroke benefit from opportunities to practice the activities they need
to re-learn. It is common practice to give patients written exercises to guide their practice
out of therapy session. Whilst more practice is better, it is important that the activities
are practiced accurately, to ensure that the right movement patterns are re-learned.
The aim of this study, is to evaluate whether an intervention providing in-patients who have
had a stroke an opportunity to use a simple video guide to help them perform their exercises
accurately would improve clinical outcomes. Watching an activity being performed helps you to
learn the activity more effectively. The focus of this study is arm rehabilitation.
The participants will be adult in-patients in Leeds Teaching Hospitals Trust, and will have
had a first time stroke that has left them with some arm weakness.
The participants will be matched according to the severity of their weakness, then randomly
allocated to either a treatment as usual group, or an intervention group. Those in the
intervention group will have their exercises for their arm and hand recorded onto a tablet
during their normal therapy session. They will then be lent the tablet for the duration of
the trial, so they can have a visual guide to help them throughout the trial period. Ward
staff will be shown how to use the tablet to help any participants who struggle with the
technology.
Measurements will be made before and after the trial period to look at ability to move the
arm and hand, quality of movement, self-efficacy and time spent exercising. Participants and
staff will be asked for their experiences of the intervention or normal practice.
This is a feasibility study with an embedded process evaluation.
This is a small single blind RCT. The outcome assessor will be blinded to the participants
status as either in the treatment as usual group or the intervention group. As a feasibility
study conducted as part of the development, and planned larger evaluation, of a complex
intervention we have drawn heavily on the MRC guidance on complex interventions and process
evaluation.
All participants will have the capacity to make an informed decision to consent.
The participants who are suitable to be included in the study will be consented by the
student researcher (with support from the Speech and language therapist if needed). This will
be done in accordance with the process described in section A27-1.
To reduce the possibility of patients who have severe impairment or other excluding factors
being approached an initial screening will have occurred by the direct clinical care team of
the potential participants medical notes. This occurs as part of their normal initial
assessment of the patient.
Eight patients with mild upper limb impairment will be recruited and eight with moderate
upper limb impairment. (Three of each category for both treatment as usual and intervention
group).
A tally will be kept of those with mild and moderate weakness in their upper limb, and
recruitment will cease once eight participants of each category have been consented. The
trial period will commence as a rolling start, with each person starting the trial period as
soon as their 'matched pair' has been recruited. Each of the matched pair will be randomly
allocated into either control or intervention group.
Once the participants have been consented, they will undergo their baseline assessments. This
will be carried out by an experienced neurological physiotherapist from another ward (Blinded
to the randomisation into the control or intervention group). The assessment session will be
carried out in one of the ward rehabilitation rooms, and is predicted to take no more than
half an hour, though more time will be allowed should the participant have further questions.
The patients in the control group will then have their therapy programme as normal for the
next four weeks, or until discharge, whichever comes sooner.
The patients in the intervention group will have their next therapy session in the normal
manner, but during or at the end of the session,(whichever is most appropriate) the exercises
prescribed by the therapist will be filmed onto a tablet. It will consist of the therapist
performing the exercise three times to allow the participant to get the idea of the correct
movement, and then the participant performing the action three times with the therapist
giving verbal prompts to correct the movement.For the intervention group the therapist will
be asked to film any upper limb exercises prescribed onto an i-pad, which will provided (one
for each patient). Filming will be from two to three feet away, and from whatever angle the
physiotherapist feels is most appropriate. The video need not include all of the patient or
physiotherapist demonstrator, but should include as much of their body as the therapist feels
is needed for guidance.
The i-pad can then be taken by the patient to be used by their bedside. Participants will be
given a prompt sheet for playing back their exercises, and the I-pad interface will have been
developed with The University of Leeds School of Medicine technology department to make it as
intuitive as possible.
For both patient groups, if the therapist would normally provide a written exercise sheet
this will also be provided.
The exercises prescribed will be updated by the therapist as deemed appropriate according to
the participants needs, either by re-recording them in a subsequent session, and/or updating
written exercise sheets.
The participants in the intervention group will have access to the tablet they are using for
the duration of the study, labelled and kept in their private bedside locker. Ward staff will
be prompted to ensure that during the day if a patient wishes to do their exercises they are
'set up' to do so, either by ensuring exercise sheets are to hand, or the tablet is within
reach, and if necessary switched on and opened, with prompts how to start the video (as the
technology may be unfamiliar to the patients.) Ward staff will also ensure the tablets are
regularly charged.
At the end of the four week period, or up to 72 hours before discharge, the baseline
assessment barrage will be repeated by the baseline assessor (still blinded, participants
prompted not to divulge group allocation) In order to evaluate the experience of exercising
out of therapy sessions, the research physiotherapist will conduct a one to one interview
with some of the patient participants. They will be selected via purposive sampling,
accounting for initial weakness category and previous experience of using tablet technology.
Open ended questions will be used to find out how easy they found it to exercise their
affected arm out of therapy time.
Questions asked will be:
- What factors made it difficult to exercise out of therapy time?
- How did you cope using the tablet? (intervention group only)
- Did the video guide influence how you performed the exercises?(intervention group only)
- What suggestions do you have to make using the tablet or video guide better?
Therapy staff will be asked in a focus group setting:
- How useful do you think the video guide was in helping your patients carry out practice
out of therapy sessions?
- How did filming the exercises impact on their normal therapy sessions?
- Do they think this intervention could work in practice?
- What would need to change to make it work?
Interviews with patient participants will be carried out in the treatment rooms or by the
patients bed if this is their preference.
The Physiotherapy team focus group will be carried out in one of the available treatment
rooms.
Patient participants will be asked if they wish to have feedback on the study, and if so home
or discharge destination contact details will be recorded, and kept securely, so the
participants can receive a written summary of the outcome after the student write up.
