Post-traumatic shoulder 'dystonia': persistent abnormal postures of the shoulder after minor trauma.
The authors describe two patients with fixed shoulder elevation and prominent regional muscle hypertrophy that developed within days after local minor injury. The condition lacked several typical features of dystonia, such as the presence of torsional movements, task specificity, or relief by antagonistic gestures. These patient reports add to the growing literature indicating that persistent post-traumatic abnormal postures and muscle hypertrophy in different body parts may be a distinct response of the nervous system to injury.
