Yale Global Tic Severity Scale (YGTSS) (Total Tic Score) The YGTSS tool gives ratings in 5 domains: Total Motor Tic Score, Total Verbal Tic Score, Total Tic Score (Motor + Verbal), Overall Impairment Rating, and Global Severity Score. When calculating the Global Severity score, it is found by adding together the total motor, verbal and impairment scores. The Total Tic Severity Score has a range of 0-50, and the Global Severity Score has a range of 0- 100. A higher score on all scales suggests a more severe Tic, or a greater impact the Tic has on the person's life.
