Swallow Training with Biofeedback in Acute Post Stroke Dysphagia

About 50% of people who have a stroke experience difficulty swallowing. There is a growing evidence base showing that swallowing therapy can help to improve swallowing, but we don't know which type or how much therapy is most beneficial. The investigators are further developing one particular intervention - swallow strength and skill training with biofeedback. This involves practicing strong or effortful swallows and practicing controlling the timing of swallowing using visual feedback on a screen showing the activity of the muscles involved in swallowing. The investigators want to know whether trained clinicians are able to deliver this therapy in acute hospital settings early after stroke. The investigators also want to explore whether there is an effect of dose in improving swallowing and other health factors. To do this the investigators will conduct a trial across several stroke units in the east midlands. The study aims to recruit 120 participants who have had a stroke and have dysphagia and who will randomly be placed in one of three groups. One group will get a standard dose therapy (10 x 35 minute sessions over 2 weeks), another group with receive a high dose therapy (20 x 35 minute sessions over 2 weeks) and the third will receive 'usual care' which is what they would usually get from their current service. The investigators will look at what therapy participants actually get, what factors might influence this and the training, support and conditions that enable clinicians to deliver the therapy. The investigators will also assess the participants swallowing and collect information on their health, face to face at the beginning and after the therapy and over the phone at three months.
