Clinical guidelines are systematically developed statements that provide practitioners and patients a ready resource for treatment options and their risks/benefits. They are based on synthesizing high-quality evidence from systematic reviews and research. The introduction of evidence-based medicine led to greater use of clinical research results in guidelines. Guidelines provide a manageable summary for busy practitioners. They are best developed by multidisciplinary panels and explicitly linking recommendations to evidence. PEDro is a major database for evidence-based physical therapy guidelines.
