ACT NoW: Assessing the Effectiveness of Communication Therapy in the North West: a Pragmatic, Multi-centre Randomised Controlled Trial

Stroke is the leading cause of long-term disability in the UK. About a third of stroke survivors will suffer some level of communication problems following the stroke. Such problems can affect parts or all of the motor apparatus responsible for producing speech, thus affecting clarity of speech and overall intelligibility (a condition known as dysarthria). Alternatively, stroke can affect the cognitive system for comprehending and formulating language (a condition known as dysphasia or aphasia). Some people will suffer impairment of both speech and language.

For these people, Speech and Language Therapy is often offered. Solid research evidence is a pre-requisite for planning evidence-based service delivery and systematic reviews for dysarthria and aphasia highlighted a lack of good quality research evidence of the effectiveness of Speech and Language Therapy. To try and rectify this situation, the ACT NoW study has been commissioned and funded by the NIHR Health Technology Assessment Programme.

The aims of the ACT NoW Study are to determine the relative effectiveness and cost effectiveness of a Speech and Language Therapy (SLT) intervention for people with aphasia and/or dysarthria following stroke, when compared with an attention control. We also aim to explore the experience and the impact of the interventions from the perspective of both users and carers, using qualitative research.

The ACT NoW study is a pragmatic, multi-centre randomize controlled trial (RCT) with a nested qualitative study and full economic evaluation. The RCT involves comparison of two arms within this target population: a manualized Speech and Language Therapy (SLT) intervention; and an 'attention control'. Randomization will be stratified by diagnosis/severity as well as site/centre, with an 'intention to treat' approach.

The qualitative study will comprise interviews with patients and carers, purposefully sampled from each arm of the trial, to evaluate service user preferences for communication therapy after stroke. Innovative methods of communication support have been developed to enable people with communication difficulties to engage in the interview process.
