[Validation of the German Version of the Sunnybrook Facial Grading System].
Background:The Sunnybrook facial grading system (SFGS) is frequently applied to evaluate facial function in patients with facial palsy, but still now there is no validated German version of this evaluation sheet.Methods:The original English version of the SFGS was translated and validated in accordance with international standards. The interrater reliability from 5 raters (speech therapy students) and the intrarater reliability from repeated ratings at 2 time points using video tapes of 18 patients with different types of facial palsy were analyzed by calculating the intraclass correlation coefficient (ICC) and other reliability measures.Results:ICC for the interrater reliability for the 4 components of the SFGS, resting symmetry, symmetry during voluntary movements, synkinesis, and the composite score were ICC 0.845; 0.903; 0.731 and 0.918, respectively, for the first evaluation and ICC 0.881; 0.932; 0.818 and 0.940, respectively, for the second evaluation. The mean intrarater reliability for the 4 SFGS scores was ICC=0.791; 0.906; 0.770 and 0.905.Discussion:There is now a valid German version of the SFGS available that can be used even by novices. The German version is suitable for evaluation of facial palsies in clinical routine and studies to allow a better comparability of German patients with results of the international literature.
