Introduction: Painless legs and moving toes syndrome (PoLMT) is a rare movement disorder characterized by flexion, extension, abduction, adduction, and torsion of toes in the absence of pain. It is considered a variant of painful legs and moving toes syndrome, which is characterized by similar movements but is accompanied by pain. Although neuropathy, spinal cord compression, brain tumor, cerebral infarction, and Wilson's disease have been reported to be associated with PoLMT, the actual cause, trigger, and mechanism remain unclear. Therefore, a standardized treatment for PoLMT is not established yet. Case Presentation: We describe a 64-year-old Japanese woman with no past medical history who presented with nonrhythmic repetitive involuntary toe movement of the left foot in the absence of pain. She was diagnosed with idiopathic PoLMT and treated with a low dose of clonazepam (0.5 mg/day). The involuntary movement disappeared completely several days after treatment. Conclusion: A low dose of clonazepam is effective in the treatment of PoLMT.
