Sunnybrook facial grading system: Reliability and criteria for grading

In clinical research, which is distinctly quantitative and rigidly fixed to a written protocol, the need for precision is great, especially when multicenter trials are planned. The Sunnybrook Facial Grading System (SB) is a well‐established tool for assessing facial movement outcomes; however, some ambiguities do arise. The purpose of this study was to construct specific grading criteria and to test the intra‐rater and inter‐rater reliability before and after the use of these criteria. The hypothesis was that even in naïve observers, specific criteria improve reliability.
