Institut National de la Santé Et de la Recherche Médicale, France
ClinicalTrials.gov Identifier:
NCT01682668
First received: July 19, 2012
Last updated: February 23, 2017
Last verified: February 2016
  Purpose
This program aims to understand the role of the subthalamic nucleus in the control of the movement in healthy humans and patients with Parkinson's disease, how the STN dysfunction contributes to akinesia and how the STN stimulation improves motor signs in PD patients .

Condition Intervention
Parkinson's Disease
Procedure: Bilateral subthalamic stimulation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Basic Science
Official Title: Role of the Subthalamic Nucleus in the Control of Movement: Physiopathology of Akinesia in Parkinson's Disease.

Further study details as provided by Institut National de la Santé Et de la Recherche Médicale, France:

Primary Outcome Measures:
  • Firing rate of the subthalamic neurons [ Time Frame: During surgery for bilateral STN stimulation ]
    Changes in the neuronal activity of the STN before, during and after the execution of an arm movement


Secondary Outcome Measures:
  • Evoked related potentials of the STN [ Time Frame: 3-5 days after surgery for bilateral STN stimulation ]
    Local-field potentials recordings with DBS electrodes when performing the execution of an arm movement or gait initiation

  • Biomechanical parameters of gait initiation [ Time Frame: 6 months ]
    Gait initiation parameters by using a forceplate and EMG recordings


Other Outcome Measures:
  • BOLD signal during fMRI [ Time Frame: 1 month before surgery ]
    Changes in the BOLD signal during fMRI with virtual imagery of movement


Estimated Enrollment: 60
Study Start Date: February 2013
Estimated Study Completion Date: September 2018
Estimated Primary Completion Date: September 2018 (Final data collection date for primary outcome measure)
