Brief Summary
54 patients with idiopathic Parkinson's disease and freezing of gait resistant to subthalamic nucleus stimulation and dopaminergic medication will be included into this multicentre randomised controlled double-blinded parallel group clinical trial. The treatment consists of two different stimulation settings using (i) conventional stimulation of the subthalamic nucleus \[standard STN\] as active comparator and (ii) combined stimulation of active electrode contacts located in both the subthalamic nucleus and substantia nigra pars reticulata \[STN+SNr\].

Study Arms (2)
[standard STN]
ACTIVE COMPARATORDevice: standard stimulation on subthalamic (STN) contacts
[STN+SNr]
EXPERIMENTALDevice: Combined stimulation of the subthalamic nucleus (STN) and the substantia nigra pars reticulata (SNr)
Interventions
High frequency deep brain stimulation with variable (best individual) stimulation on subthalamic contacts
high frequency deep brain stimulation of combined (best individual) subthalamic and nigral stimulation
Eligibility Criteria
You may qualify if:
- Idiopathic Parkinson's disease (according to the "British Brain Bank criteria" (Hughes, 1992) including genetic forms
- Therapy with STN-DBS (deep brain stimulation) (ACTIVA pulse generators) at least six months from surgery
- Activa PC (Primary Cell) or Activa RC (Rechargeable Cell) as implanted pulse generator with "Interleaving" programming option
- Localization of an active electrode contact in the subthalamic nucleus
- Localization of the caudal electrode contacts in the substantia nigra pars reticulata area (coordinates relative to midcommisural Point (MCP):
- left: -7mm ≤ x ≤ -12mm; -2mm ≤ y ≤ -6mm; -6mm ≤ z ≤ -10mm right: 7mm ≤ x ≤ 12mm; -2mm ≤ y ≤ -6mm; -6mm ≤ z ≤ -10mm (x = medio-lateral, y = anterio-posterior, z = rostro-caudal)
- ≥ 30% improvement in UPDRS III with 'standard STN' compared to 'stimulation off' in dopaminergic off
- Freezing of Gait Assessment Course ≥10 and ≤33
- Patient not wheelchair-bound and possible to move self-dependently outside a freezing episode.
- Disease duration ≥ 5 years
- Age: between 18 and 80 years
- Dopaminergic medication constant for at least four weeks prior to study enrolment
- Written informed consent
You may not qualify if:
- Participation in other clinical trials within the past three months and during enrolment in our study
- Cognitive impairment (Mini Mental State Exam \< 20)
- Suicidality, Psychosis
- Other severe pathological chronic condition that might confound treatment effects or interpretation of the data
- Pregnancy
- Paradoxical levodopa-induced "on" state freezing (Espay et al., 2012)
