NCT03470324

Brief Summary

20 patients with idiopathic Parkinson's disease and dysphagia will be included into this 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 \[STN+SNr\]. Both groups receive additional swallowing therapy as standard of care.

Outcome Measures

Primary Outcomes (1)

  • Penetration Aspiration Scale

    8-point interval scale (range 1 - 8) to describe penetration and aspiration events . Scores are determined primarily by the depth to which material passes in the airway and by whether or not material entering the airway is expelled. (Rosenbek et al, 1996). The score is obtained in swallowing of fluids

    Outcome after eight weeks (V2) with reference to baseline (V1)

Secondary Outcomes (11)

  • MDS-UPDRS parts I, II, III and IV

    Outcome after eight weeks (V2) with reference to baseline (V1)

  • Capsit-PD

    Outcome after eight weeks (V2) with reference to baseline (V1)

  • Freezing of Gait Assessment Course (FOG-AC)

    Outcome after eight weeks (V2) with reference to baseline (V1)

  • PDQ-39

    Outcome after eight weeks (V2) with reference to baseline (V1)

  • Dysphagia-related Quality of Life (SWAL-QoL)

    Outcome after eight weeks (V2) with reference to baseline (V1)

  • +6 more secondary outcomes

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • cognitive competence to consent
  • 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 sub thalamic 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
  • Penetration-Aspiration-Scale ≥ 3 or more than 20% utilization of vallecular space and/or pyriform sinuses post swallowing
  • Disease duration ≥ 5 years
  • Age: between 18 and 80 years
  • Dopaminergic medication constant for at least two weeks prior to study enrollment
  • Written informed consent

You may not qualify if:

  • Participation in other clinical trials within the past three months and during study enrolment
  • Cognitive impairment (Mini Mental State Exam \< 20)
  • Severe depressive episode with or without psychotic symptoms and suicidality (ICD-10: F32.2, F32.3), psychosis (ICD-10: F23.-)
  • Other severe pathological chronic condition that might confound treatment effects or interpretation of the data
  • Pregnancy
  • Infection and pneumonia at the time of study enrollment
  • Other competing cause for dysphagia (e.g. stroke, operation, radiotherapy)
