Abstract
Summary We report the results of electromyographic (EMG) guidance in the treatment of cervical dystonia with botulinum toxin. Eight-four patients received a total of 225 injection sessions. Overall there was moderate objective improvement in 78.7%. The mean dose of toxin was 269 ± 39 mouse lethal units and the mean duration of maximum effect was 107 ± 49 days. Complications included excessive neck weakness in 16.0% and dysphagia in 11.1% of the injection sessions. We conclude that EMG guidance is a safe and effective method of administering botulinum toxin in the treatment of cervical dystonia.Keywords
