Growth in the Physiotherapy Evidence Database (PEDro) and use of the PEDro scale.

The authors describe the growth in use of the physiotherapy evidence database (PEDro). It was shown that the number of records on the bibliographic database had doubled every 3.5 years, and now indexes reports of over 18,000 randomised trials and 3,500 systematic reviews. The usability of the database scale improved through translations and psychometric validation. The authors also describe the number of systemic reviews indexed on the Cochrane Library that searched PEDro for eligible trials.
