PEDro: The Physiotherapy Evidence Database

This database is an initiative of the Centre for Evidence-Based Physiotherapy (CEBP) at the University of Sydney, Australia. It has been developed to provide rapid access to bibliographic details and abstracts of randomised controlled trials, systematic reviews, and evidence-based clinical practice guidelines in physical therapy. Most trials have been rated for quality to help one quickly discriminate between trials that are likely to be valid and interpretable and those which are not. Their tutorial provides a step-by-step guide on how to distinguish between probably valid and potentially invalid trials.
