Beschreibungen/Notizen

• We retrospectively evaluated 118 patients with cervical dystonia (CD) treated with botulinum toxin type A (BTX-A) for the following variables: gender, age at evaluation, age at symptom onset, disease duration, presence of head/neck pain and/or tremor, pattern of head deviation, disease progression (spreading of symptoms), etiology (primary vs. secondary), pretreatment with oral medication, and Tsui score. We investigated whether these parameters could predict the clinical outcome in a short- (<30 days) and long-term basis. On short-term treatment, there were no clinically significant differences between BTX-A responsive and non-responsive patients. On long-term treatment, however, intake of oral medication previously to BTX-A injection and higher Tsui scores were predictors of favorable response. These results suggest that the greater CD severity the more likely patients will respond to BTX-A.
