14例局部或节段性不自主运动影响耳朵、背部、肩带、上肢以及腹部和骨盆带。这些运动障碍的不同寻常的位置和外观将它们与公认的运动障碍综合征区分开来。有人认为，运动的缓慢、弯曲和半节律性特征以及引起它们的运动单位活动的可变长时间爆发最符合肌张力障碍的频谱。在一些病例中，受影响区域的疼痛史和/或外周创伤也表明外周因素可能在其发病机制中起作用。
Fourteen patients with focal or segmental involuntary movements affecting the ears, back, shoulder girdle, and upper extremity, as well as the abdomen and pelvic girdle, are presented. The unusual locations and appearance of these dyskinesias distinguishes them from recognized movement disorder syndromes. It is argued that the slow, sinuous, and semirhythmic character of the movements and the variable long-duration bursts of motor unit activity responsible for them most closely fit into the spectrum of dystonia. A history of pain in the affected region and/or peripheral trauma in some cases also suggests that peripheral factors may play a role in their pathogenesis.
