People with motor apraxia after stroke often have difficulty carrying out everyday activities such as making a hot drink. Some people cannot select the right object at the right time or have difficulty using objects (such as a spoon) correctly. Apraxia is not due to muscle weakness or sensory loss. Instead it seems to be a loss or disturbance of the conceptual ability to organise actions to achieve a goal. This review of three studies, including 132 participants, suggests that further high quality research is required before specific treatment techniques can be accepted or rejected. Patients with apraxia should continue to receive general stroke rehabilitation services but better quality research is needed to identify optimal apraxia treatments.
Vollständige Zusammenfassung lesen
Apraxia is a cognitive disorder that can occur after stroke. It prevents a person from carrying out a learned movement. Various interventions are used to treat apraxia but evidence of their benefit has been lacking.
Zielsetzungen
To determine which therapeutic interventions targeted at motor apraxia reduce disability.
Suchstrategie
We searched the Cochrane Stroke Group Trials Register (last searched November 2006). In addition, we searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2006), MEDLINE (1966 to November 2007), EMBASE (1980 to November 2006), CINAHL (1982 to November 2006), PsycINFO (1974 to November 2006), the Research Index of the Occupational Therapy Journal (searched November 2006), REHABDATA (1956 to November 2006), the National Research Register (searched November 2006) and Current Controlled Trials Register (searched November 2006). We reviewed the reference lists of all articles that we identified as relevant. We made efforts to find both published and unpublished trials by writing to key authors and journals.
Auswahlkriterien
Randomised controlled trials of therapeutic intervention for motor apraxia in stroke.
Datensammlung und ‐analyse
One review author searched the titles, abstracts and keywords. Four review authors extracted data and analysed trial quality. We contacted investigators for further details of trials if necessary.
Hauptergebnisse
Three trials including a total of 132 participants were included in the review. There was evidence of a small and short-lived therapeutic effect in the two studies that reported change in activities of daily living (102 participants) but this was not considered clinically significant and did not persist at the longer-term follow up.
Schlussfolgerungen der Autoren
There is insufficient evidence to support or refute the effectiveness of specific therapeutic interventions for motor apraxia after stroke. Further research of higher quality is required. As we did not review whether patients with apraxia benefit from rehabilitation input in general, they should continue to receive general stroke rehabilitation services.
