A Description of the Trials, Reviews, and Practice Guidelines Indexed in the PEDro Database

This perspective provides an overview of the randomized controlled trials, systematic reviews, and evidence-based clinical practice guidelines in physical therapy. Data from the Physiotherapy Evidence Database (PEDro) are used to describe key events in the history of physical therapy research and the growth of evidence of effects of interventions used in the various subdisciplines of physical therapy. The 11,494 records that were identified reveal a rich history of physical therapy research dating back to the first trial in 1929. Most of the randomized controlled trials, systematic reviews, and evidence-based clinical practice guidelines in physical therapy have been published since the year 2000. This rapid growth presents a challenge for physical therapists who want to keep up to date in clinical practice.
