Parkinson’s Disease Therapy Study

Recruitment Closed


We are seeking individuals with Parkinson’s Disease for a study investigating the impact of multimodal non-invasive neuromodulation and intensive physical therapy on balance.

What the study will include

This study will compare the effectiveness of a 2-week intervention of physical therapy alone to physical therapy + neurostimulation on balance in individuals with Parkinson’s Disease.

Neurostimulation includes two different non-invasive devices:

  • The first is the Portable Neuromodulation Stimulator (PoNS™). The use of the PoNS™ device in this study is investigational. Brain stimulation via the PoNS™ device stimulates two cranial nerves connected to the tongue, and is thought to aid in neuroplasticity.
  • Galvanic Vestibular Stimulation (GVS) delivers a mild electrical current to the vestibular nerves located directly underneath the skin behind your ears. Similar to PoNS™ stimulation, GVS is thought to aid in neuroplasticity.

The use of the PoNS™ and GVS devices in this study is investigational.
Participants will have continued access to their unique PoNS™ device after study completion.


You may qualify as a study participant if:

  • You have a diagnosis of idiopathic Parkinson’s Disease


  • Approximately 4-weeks including:
    • Screening and baseline visit
    • Intervention:
      • Two 90min sessions per day
      • 5 days per week for 2 weeks


The study requires you to participate in-person at the Surrey Neuroplasticity Clinic (located at Unit 1004, City Centre 3, 13761 96 Ave., Surrey, BC, V3V 0E8).
