Plain English Summary

Background and study aims
A stroke occurs when the blood supply to part of the brain is cut off. Around one in two stroke sufferers will have difficulties with swallowing which can complicate their recovery and reduces quality of life. Swallowing problems happen when the part of the brain that controls swallowing is injured by the stroke itself. Swallowing recovers naturally in a proportion of people when the healthy side of the brain adapts and takes over the control of swallowing. There is new evidence that stimulating the healthy side of the brain can speed up this natural recovery process (called plasticity). The aim of this study is to find out if low current brain stimulation to the healthy side of the brain can speed up swallowing recovery and improve quality of life after stroke, and to establish the most effective dose of the treatment.

Who can participate?
Patients having difficulty swallowing (dysphagia) after having suffered a stroke

What does the study involve?
Not provided at time of registration

What are the possible benefits and risks of participating?
The results of this study will provide evidence for using this new approach for dysphagia rehabilitation. The expectation is that this portable user-friendly non-invasive stimulation will be rapidly rolled out into a larger study for use in rehabilitation and lead into changes in practice at a national level in the NHS.

Where is the study run from?
University of Manchester (UK)

When is the study starting and how long is it expected to run for?
April 2015 to September 2017

Who is funding the study?
National Institute for Health Research (UK)

Eligibility

Participant type(s)Patient
Age groupAdult
SexBoth
Target number of participantsPlanned Sample Size: 45; UK Sample Size: 45
Participant inclusion criteria1. All patients with dysphagia following acute anterior or posterior cerebral circulation stroke that present dysphagia for the first time, within the first weeks from symptoms and up to 6 weeks post stroke. The presence of dysphagia will be based on the results of screening procedures by the research team. Patients will be always recruited after 48-72 hours post lesion
2. There is no age limit
3. Patients must be medically stable
4. Lesions have to be verified on imaging techniques, either magnetic resonance (MR) scan or computerised tomography (CT), information which will be collected
Participant exclusion criteria1. Advanced dementia
2. Other neurological conditions that may explain swallowing difficulty (dysphagia)
3. Previous history of dysphagia
4. Presence of cardiac pacemaker of implanted cardiac defibrillator
5. Any metal in the head or eyes
6. Use of medication which decreases seizure threshold
7. A diagnosis other than stroke is suspected (e.g. brain tumour)
8. Any severe concomitant chronic medical condition that compromises cardiac or respiratory status,
9. Significant structural abnormalities of the mouth or throat
10. Patients requiring oxygen treatment will be excluded at point of entry to prevent further compromise to already impaired respiratory system
11. Patients may be reconsidered for recruitment if they are successfully weaned off oxygen treatment
