Modified Rush Video-Based Tic Rating Scale (MRVS-R)

The Modified Rush Video-Based Tic Rating Scale–Revised is a revision of the modified Rush Video-based tic rating scale published in 1999. The new version has a more detailed standardization of the recording and rating process, a reduction of the recording time from 10 min to 5 min, and an adaptation of the items. The items are rated in a scoring system from 0 - 5 and are adapted to the wording of the Yale Global Tic Severity Scale. Furthermore, the item tic frequency is now based on empirical data. In summary, the patient is filmed for 5 minutes in full body frontal view. A defined one-minute sequence is analyzed using four items to assess vocal and motor tic severity. Finally, a global score is calculated.
