A Case of Peripherally Induced Task-Specific "Lipstick Dystonic Tremor"

Tremor Other Hyperkinet Mov (N Y). 2019 Oct 1:9. doi: 10.7916/tohm.v0.689. eCollection 2019.

Abstract

Background: Peripherally induced movement disorders (PIMDs) represent a rare and debated complication of peripheral trauma.

Phenomenology shown: We report a case of task-specific "lipstick" jerky dystonic tremor as a consequence of traumatic shoulder injury, successfully treated with EMG-guided botulinum toxin injections.

Educational value: This case expands the phenotypic spectrum of PIMDs, with a visual example of a task-specific dystonic tremor after peripheral trauma, and the efficacy of EMG-guided botulinum toxin treatment in the setting of posttraumatic dystonic tremor.

Keywords: Dystonic tremor; botulinum toxin; electromyography; lipstick; movement disorders; peripherally induced; posttraumatic; task specific.
