Interventions for apraxia of speech following stroke.

BACKGROUND

Apraxia of speech is a communication disorder that can affect stroke patients. Several different intervention strategies are undertaken by speech and language therapists working with this patient group.

OBJECTIVES

To assess whether therapeutic interventions improve functional speech in stroke patients with apraxia of speech and which individual therapeutic interventions are effective.

SEARCH STRATEGY

We searched the Cochrane Stroke Group Trials Register (searched May 2004). In addition, we searched the following databases: the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2003); MEDLINE (1966 to April 2004); EMBASE (1980 to April 2004); CINAHL (1982 to April 2004); PsycINFO (1974 to April 2004); the National Research Register (searched April 2004); and Current Controlled Trials Register (searched May 2004). We reviewed reference lists of relevant articles and contacted authors and researchers in an effort to identify published and unpublished trials.

SELECTION CRITERIA

We sought to include randomised controlled trials of non-drug interventions for adults with apraxia of speech following a stroke where the primary outcome was functional speech at six months follow up.

DATA COLLECTION AND ANALYSIS

One author searched the titles, abstracts and keywords. Two authors examined the abstracts that might meet the inclusion criteria. Four authors were available to assess trial quality and to extract data from eligible studies.

MAIN RESULTS

No trials were identified.

AUTHORS' CONCLUSIONS: There is no evidence from randomised trials to support or refute the effectiveness of therapeutic interventions for apraxia of speech. There is a need for high quality randomised trials to be undertaken in this area.
