A woman with chronic posttraumatic axial lateropulsion cervical dystonia ("belly dancer's head") found relief of her spontaneous dystonic spasms by the sequential performance of an elaborate motor ritual. During an episode of left optic papillitis caused by central retinal vein occlusion, gaze-evoked amaurosis of the left eye developed, preceded by achromatopsia, during left lateral gaze. Gaze-evoked amaurosis triggered axial dystonia, which was followed by her unique, stereotyped, dystonia-relieving ritual that simulated a slow dance. Visual symptoms improved progressively in 1 year. Eventually, she was unable to trigger her dystonia by eye movements. Spontaneous dystonia remained otherwise unchanged from before the episode of papillitis and was still relieved by her unique ritual.
一名患有慢性创伤后轴向侧推性颈部肌张力障碍（“肚皮舞女头部”）的女性，通过依次进行精心设计的运动仪式，其自发性肌张力障碍性痉挛得到缓解。在由视网膜中央静脉阻塞引起的左侧视乳头炎发作期间，左侧眼睛出现凝视诱发性黑矇，在向左外侧凝视时先出现色觉障碍。凝视诱发性黑矇引发了轴向肌张力障碍，随后是她独特的、刻板的、缓解肌张力障碍的仪式，类似于慢舞。视觉症状在1年内逐渐改善。最终，她无法通过眼球运动触发肌张力障碍。自发性肌张力障碍在视乳头炎发作之前没有其他变化，并且仍然可以通过她独特的仪式得到缓解。
