Pedro - PEDro is the Physiotherapy Evidence Database. It has been developed to give rapid access to bibliographic details and abstracts of randomised controlled trials, systematic reviews and evidence-based clinical practice guidelines in physiotherapy. Most trials on the database have been rated for quality to help you quickly discriminate between trials which are likely to be valid and interpretable and those which are not.

Physiotherapy Choices - Physiotherapy Choices is a database designed for use by consumers of physiotherapy services, including patients, their friends and families, health service managers, and insurers. The database provides a catalogue of the best research evidence of the effectiveness of physiotherapy interventions. Three sorts of research evidence are catalogued including clinical trials (individual research studies of the effects of physiotherapy), reviews (scientific compilations of the evidence from randomised controlled trials), and guidelines (recommendations regarding physiotherapy, based wherever possible on randomised trials and systematic reviews.)
