Subthalamic Nucleus Stimulation Effect on Gait Symmetry and Freezing of Gait
Subthalamic Nucleus Stimulation Effect on Gait Symmetry and Freezing of Gait
Impact of unilateral modulation of deep brain stimulation of the subthalamic nucleus on freezing of gait in Parkinson's disease
Unilateral modulation of subthalamic stimulation and its impact on freezing of gait in Parkinson's disease will be studied.
In a cross-over, doubleblind, randomized study, a 30% reduction of stimulation intensity of the less impacted side will be compared with chronic treatment with regard to frequency and duration of freezing of gait episodes.
Inclusion Criteria:
Patients affiliated to social security Patient with idiopathic parkinson's disease, with deep brain stimulation since at least one year Freezing of gait Able to give inform consent
Exclusion Criteria:
Patient under guardianship, legal guardianship Psychosis Severe depression Severe cognitive troubles (Mattis < 130) Other neurologic or medical pathology interfering with gait
