Researchers need to use the best available evidence to make recommendations for practitioners and consumers. This workshop explains how research designs other than randomized controlled trials (RCTs) yield evidence that could be included in systematic reviews. A systematic review "strives to comprehensively identify, appraise, and synthesize all the relevant studies on a given topic" (Petticrew & Roberts, 2006, p. 19). Systematic reviews examine the results of multiple studies that fit defined criteria, in order to limit bias and to identify evidence that emerges from the review. Most systematic reviews use criteria that outline a hierarchy of evidence, with the 'gold standard' identified through RCTs. However, much disability and rehabilitation research consists of evidence generated by quasi-experimental designs including single subject designs.
