Abstract(s)
Speech and language therapy (SLT) benefits people with aphasia following stroke. Group level summary statistics from randomised controlled trials hinder exploration of highly complex SLT interventions and a clinically relevant heterogeneous population. Creating a database of individual participant data (IPD) for people with aphasia aims to allow exploration of individual and therapy-related predictors of recovery and prognosis. To explore the contribution that individual participant char acteristics (including stroke and aphasia profiles) and SLT intervention components make to language recovery following stroke. Methods and procedures: We will identify eligible IPD datasets (including randomised controlled trials, non-randomised comparison studies, observational studies and registries) and invite their contribution to the database. Where possible, we will use meta and network meta-analysis to explore language performance after stroke and predictors of recovery as it relates to participants who had no SLT, historical SLT or SLT in the primary research study. We will also examine the components of effective SLT interventions. Outcomes include changes in measures of functional communication, overall severity of language impairment, auditory comprehension, spoken language (including naming), read ing and writing from baseline. Data captured on assessment tools will be collated and transformed to a standardised measure for each of the outcome domains. Our planned systematic-review-based IPD meta- and network meta-analysis is a large scale, international, multidisciplin ary and methodologically complex endeavour. It will enable hypotheses to be generated and tested to optimise and inform development of interventions for people with aphasia after stroke. The protocol has been registered
at the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42018110947).
