Trial Outcomes & Findings for CD-PROBE: Cervical Dystonia Patient Registry for the Observation of onabotulinumtoxinA Efficacy (NCT NCT00836017)

NCT ID: NCT00836017

Last Updated: 2014-07-17

Results Overview

TWSTRS is an assessment scale used to measure the impact of cervical dystonia on patients. The score is comprised of 3 subscales: Severity, Disability, and Pain, each of which is scored independently. The total of these 3 subscales comprises the TWSTRS total score which is scored from 0 (least symptoms) to 85 (worst symptoms). Higher scores indicate a greater degree of symptom severity.
