REM Sleep Behavior Disorder (RBD) are abnormal motor behaviors corresponding to the dream enactment occurring during REM sleep. RBD is frequently a harbinger for Parkinson’s disease (PD). RBD can appear few years before the usual signs of Parkinson’s disease.


The aim of our study is to identify early gait disorders in patients with idiopathic RBD. To sensitize our tests we will ask the subjects to walk in “dobble task”: they will have to walk and do calculation at the same time.



Patients with RBDD are age (+/- 3 years) and sex matched to patients with PD and controls.




We have already included all patients with RBD

We are now looking for the group of patients with PD


  • To have an idiopathic Parkinson’s disease according to the international criteria (United Kingdom Parkinson’s Disease Society Brain Bank: Gibb and Lees, 1988; Hughes et al., 1992)
  • To have no obvious gait disorder



  • To have atypical parkinsonism (Parkinson plus) : presence of oculomotor disorders, early falls, hallucinations, dementia, severe and early dysautonomia
  • To have obvious gait disorder
