The objective of this study was to determine whether there is a set of specific postures that are common between different children with dystonia. Methods Videotapes were examined from all children who were seen in a pediatric movement disorders clinic over a 4‐year period and had a diagnosis of nonpsychogenic dystonia. In total, 179 children were included in the video review. Results Visually similar postures were identified in 152 different children. Seven different common postures were identified. All 152 children exhibited at least 1 of these postures, and most had more than 1. Conclusions Involuntary postures in childhood dystonia exhibit unexpected similarities despite a wide range of underlying etiology, severity, and developmental experience. This is consistent with the hypothesis that childhood dystonia is a symptom that reflects a shared pathway of expression for multiple anatomic and functional abnormalities.
