Brief Summary:

The goal of this study is to determine whether external neuromodulation using transcranial electrical stimulation (TES) can reduce the perception of self-motion that is experienced by patients with MdDS. Mal de debarquement is translated as the "sickness of disembarkment," and refers to the chronic feeling of rocking dizziness that occurs after exposure to passive motion. A similar form of rocking dizziness can be experienced without a motion trigger in individuals with certain risk factors.

Treatment for MdDS is limited and morbidity is high.The goal of the study is to determine whether TES can suppress the rocking dizziness of MdDS either as a standalone therapy or as an adjunctive therapy to other forms of neuromodulation such as transcranial magnetic stimulation. The investigators will determine the optimal treatment duration and stimulation parameters.


Condition or disease Intervention/treatment Phase
Mal de Debarquement Syndrome Device: Transcranial Electrical Stimulation Not Applicable

Detailed Description:

Eligible participants who meet study criteria and pass the safety screen will be invited to participate in the study. If TES is used as add-on treatment to repetitive transcranial magnetic stimulation (rTMS), the training for TES application will be done on-site. However, in a portion of the study that does not involve rTMS, remote training will be performed via a webcam provided that a suitable "Study Buddy" is available to assist the participant.

Participants will maintain web-based diaries of their symptoms for up to four weeks prior to treatment with TES. Before the actual treatment sessions are started, the subjects will complete baseline questionnaires online which will be repeated once a week for up to 12 weeks. Over the course of the study, the subjects will also keep a daily log of their sessions such as how many sessions they performed, for how long, and whether they had any side effects with each session.

The studies will include a sham arm, allocated at a ratio of 1:1. On-site studies will involve the application of EEG, MRI, balance, cognitive, and visual/auditory stimulation tests.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Transcranial Electrical Stimulation-Real
The participant will perform real TES. The forms of TES used in this study will include transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), or transcranial random noise stimulation (tRNS). Each stimulation session will last for 20-minutes.
 Device: Transcranial Electrical Stimulation
A form of external neuromodulation using electrodes on the surface of the head. We will be using the TCT tDCS device (www.trans.cranial.com) or devices constructed by our research group or collaborators.
Other Names:
  • Transcranial Direct Current Stimulation (tDCS)
  • Transcranial Alternating Current Stimulation (tACS)
  • Transcranial Random Noise Stimulation (tRNS)
  • Sham Transcranial Stimulation
Sham Comparator: Transcranial Electrical Stimulation-Sham
The participant will perform sham TES for 20-minutes. The form of sham TES will depend on the active arm, e.g. if tACS is on the active arm, then the sham tACS will be a different frequency of stimulation. If tDCS is the active arm, then a short ramp up of tDCS followed by a ramp down (about 60-seconds) will be used as the sham arm.
 Device: Transcranial Electrical Stimulation
A form of external neuromodulation using electrodes on the surface of the head. We will be using the TCT tDCS device (www.trans.cranial.com) or devices constructed by our research group or collaborators.
Other Names:
  • Transcranial Direct Current Stimulation (tDCS)
  • Transcranial Alternating Current Stimulation (tACS)
  • Transcranial Random Noise Stimulation (tRNS)
  • Sham Transcranial Stimulation
