28 September 2015	New search has been performed	The scope of the updated review has broadened since the previous version. This was in response to a request from the Cochrane Stroke Group to incorporate evidence relating to cognitive function (including neglect) into this update. We have rerun and expanded the searches to February 2015 and revised the text as appropriate. We have included 32 trials involving 748 participants in this update compared with 15 trials with 455 participants in the last version of this review from 2013.
