Fixed dystonia leads to an immobile abnormal posturing of the affected limb. There is an ongoing debate whether this condition is psychogenic in origin.
We present a 21-year-old violinist with fixed dystonia after an acute overuse injury with a transient cyanosis but no signs for psychological trauma. After Incobotulinumtoxin injection, symptoms subsided within 8 hours.
Our case corroborates the notion that fixed dystonias after minor injuries are functional disorders. It underlines the necessity of a biopsychosocial approach to functional disorders, considering the possibility of an overlay between organic and non-organic disorders.
固定性肌张力障碍会导致受影响肢体出现无法活动的异常姿势。关于这种情况是否起源于心理因素，目前仍存在争议。
我们报告一名21岁的小提琴手，在急性过度使用损伤后出现固定性肌张力障碍，伴有短暂性发绀，但无心理创伤迹象。注射incobotulinumtoxin后，症状在8小时内消退。
我们的病例证实了轻伤后出现的固定性肌张力障碍是功能性障碍这一观点。它强调了对功能性障碍采用生物心理社会方法的必要性，同时要考虑到器质性和非器质性障碍重叠的可能性。
