Objective: To evaluate which of the five classification systems is simpler to understand a Physical therapy evidence levels and grades of recommendation Design: Randomized controlled trial, pilot study. Participants: Physical therapy dedicated to musculoskeletal rehabilitation. Intervention: Case report describing a female patient diagnosed with mild osteoarthritis of the right knee, a specific Medline search was performed to answer the following question: Can therapeutic ultrasound reduce pain and improve physical function? A systematic review that answers the question was not found. The same evidence was presented differently according to the following categories of evidence: NICE, SIGN, GRADE, EMBC and CTPHC. Results: 8 therapists agreed to participate. A GRADE 87.5 % considered the simplest classification compared to 12.5 % (other systems), with a RR = 7.0 (1.090, 95% CI 44.6) and Risk Difference DR = 75 % (42.59, 95% CI 107.4). To see the association showing the relationship between the exposed and unexposed GRADE classification system was used Chi2 statistical Mantel-Haenszel, with a value p = 8.438. Conclusion: Apparently GRADE is the most simple for therapists to understand how scientific evidence.
