Introduction

There is a unique opportunity for SLTs working in respiratory roles to engage in collaborative research. Current speech and language therapy evidence, particularly in the field of chronic cough and vocal cord dysfunction, is lacking and robust, prospective, well-designed research projects are missing from the literature.

To continue to evolve this emerging respiratory speech and language therapy role effectively, it is imperative that research into best practice occurs, to direct and underpin future care models of intervention.

Here you will find a summary of evidence and research relating to adult respiratory care and the role of speech and language therapy.

Visit the RCSLT Research Centre for information and resources to support your evidence-based practice; ways to enhance your continuing professional development (CPD); information about clinical academic careers; resources to help you get involved in research and much more.
