This issue of Physiotherapy includes citations from an increasingly important source of evidence for healthcare interventions: The Cochrane Database of Systematic Reviews. Contained within The Cochrane Library, the Cochrane Database of Systematic Reviews is an electronic rather than a paper publication. Physiotherapists, in common with other health professionals, can no longer ignore the growth and potential usefulness of electronically disseminated information, as shown by the scope and number of recently published systematic reviews that have been conducted within the Cochrane Collaboration and are of relevance to physiotherapists. A selective list of titles after this leading article is followed by four abstracts of recently published reviews. Further selections will be published quarterly.
