Abstract
Isolated foot dystonia following exercise is a rare manifestation of early PD. It may precede the onset of parkinsonism by years and can be clinically indistinguishable from familial exercise-induced dystonia. The authors present a patient with dystonic claudication where dopamine transporter SPECT using (123)I-FP-CIT allowed early diagnosis of PD and enabled effective symptomatic treatment with a dopamine agonist.
