PEDro is the Physiotherapy Evidence Database. PEDro is a free database of over 18,000 randomised trials, systematic reviews and clinical practice guidelines in physiotherapy. For each trial, review or guideline, PEDro provides the citation details, the abstract and a link to the full text, where possible. All trials on PEDro are independently assessed for quality. These quality ratings are used to quickly guide users to trials that are more likely to be valid and to contain sufficient information to guide clinical practice. PEDro is produced by the Centre for Evidence-Based Physiotherapy at The George Institute for Global Health.
