American Congress of Rehabilitation Medicine and Practice ResourcesAs a component of an interdisciplinary organization, the EPC has reviewed the validity of nationally and internationally respected approaches to evidence synthesis. The EPC has selected the methodology developed by the American Academy of Neurology (AAN) as the preferred way of developing guidelines for rehabilitation professionals. While the AAN method is the preferred basis, reviews and guidelines developed using other recognized evidence-based methods such as those of the Cochrane Collaboration, the Appraisal of Guidelines for Research and Evaluation (AGREE) collaboration, Grades of Recommendation, Assessment, Development, and Evaluation (GRADE), the Institute of Medicine, and the Agency for Healthcare Research and Quality will also be considered for ACRM endorsement. The EPC also develops materials and standards to improve the synthesis of research information and its application to rehabilitation in practice.
