first be established. Most randomized trials in stroke rehabilitation are too small to provide a reliable answer in their own right [6] and so we need to include all relevant trials in rigorous systematic reviews. Such reviews of the evidence can also help counter concerns that individual rehabilitation trials are only relevant to their local area or specific circumstances (i.e. have poor generalizability). If these reviews are to usefully inform both current clinical practice and future research, they must be relevant and accessible to rehabilitation clinicians and healthcare users: i.e. they must be relevant, reliable, accessible and understandable;
