This study presents the case of a 39-yr-old woman who had atypical involuntary
dystonic movements of the shoulder and back. Ten months earlier, she was involved
in a motor vehicle collision. Involuntary movements developed abruptly 3 wks
before her first visit to the clinic. Her involuntary movements had some atypical
features, such as continuous, bizarre, and rhythmic or semirhythmic
characteristics, and showed mixed symmetric and asymmetric patterns. She was
treated successfully with electromyography-guided botulinum toxin type A
injection. Involuntary dystonic movements may be due to posttraumatic dystonia, a
relatively uncommon diagnosis. Atypical posttraumatic dystonia may be managed
effectively with botulinum toxin type A injections.
