The syndrome of painful legs and moving toes consists of continuous or semicontinuous involuntary writhing movements of the toes associated with pain in the affected extremity. We report a 57-year-old man with a 33-year history of painless and semicontinuous involuntary movements of the toes of the left foot similar to those seen in painful legs and moving toes. There was no family history of movement disorder. The history and physical examination were negative for significant trauma, radiculopathy, or peripheral neuropathy. There were no other neurological findings or involuntary movements. It is unlikely that the involuntary movements were precipitated by neuroleptics or psychosis. CT scan of the head; EEG, CT, and MRI scans of the lumbosacral spine; and EMG and nerve conduction studies of the legs showed no significant abnormalities except for a predominant cocontraction of the left foot flexors and extensors at 0.6-1.2 Hz in a pattern sometimes seen in painful legs and moving toes. We conclude that there is a condition clinically and electrophysiologically similar to painful legs and moving toes that we call painless legs and moving toes, the etiology of which remains undetermined.
痛性腿部和舞动脚趾综合征表现为与受累肢体疼痛相关的脚趾持续或半持续的不自主扭动动作。我们报告一名57岁男性，有33年无痛且半持续的左脚脚趾不自主运动病史，类似痛性腿部和舞动脚趾综合征所见。无运动障碍家族史。病史及体格检查未发现重大创伤、神经根病或周围神经病。无其他神经学表现或不自主运动。不自主运动不太可能由抗精神病药物或精神病引起。头部CT扫描；腰骶椎的脑电图、CT和MRI扫描；腿部肌电图和神经传导研究均未显示明显异常，仅在0.6 - 1.2赫兹时左足屈肌和伸肌存在优势共收缩，此模式有时见于痛性腿部和舞动脚趾综合征。我们得出结论，存在一种在临床和电生理上与痛性腿部和舞动脚趾综合征相似的病症，我们称之为无痛性腿部和舞动脚趾综合征，其病因尚不确定。
