Trial Outcomes & Findings for Deep Brain Stimulation in Patients With Dystonia (NCT NCT00773604)

NCT ID: NCT00773604

Last Updated: 2019-02-19

Results Overview

Total TWSTRS score range is 0-88, where higher score indicates worse symptoms. Values are calculated by baseline minus 12 month, where higher difference score of change between baseline and 12 months means better outcome (more improvement)
