Brief Summary

Expression of hypokinetic and hyperkinetic motor symptoms in Parkinson's disease (PD) is associated with pathological synchronous oscillations of neuronal activity (local field potential/LFP) in the cortico-subcortical network with a wide frequency range. In the present project, we propose to study cortico-subcortical oscillations and their synchronization in patients operated for PD (subthalamic deep brain stimulation (STN-DBS)) during distinct pharmacological and stimulation conditions (hypokinetic and hyperkinetic), using a simple motor task.

Outcome Measures

Primary Outcomes (1)

  • Cortico-subcortical electrophysiological coherence

    Statistically significant difference in the cortico-subcortical electrophysiological coherence value between a movement performed in hypokinetic condition and a movement performed in hyperkinetic condition

    At inclusion (Day 0)

Secondary Outcomes (3)

  • Spectral signal power

    At inclusion (Day 0)

  • Effect of STN-DBS on spectral signal power

    At inclusion (Day 0)

  • Correlation between semiological characteristics

    At inclusion (Day 0)

Study Arms (1)

Recruited patient

EXPERIMENTAL

Patient with idiopathic Parkinson's disease and having a STN DBS with a PERCEPT™ for less than a year or being candidate for subthalamic nucleus deep brain stimulation with the PERCEPT™ device (first-implantation)

Other: Electrophysiological recordings

Interventions

Electrophysiological recordings will be made during a motor task in four different conditions: 1. without pharmacological treatment and without stimulation (Off condition), 2. without pharmacological treatment and during stimulation (DBS condition), 3. during pharmacological treatment and without stimulation (DOPA condition), 4. during pharmacological treatment and stimulation (DOPA+DBS condition).

Recruited patient
