An interventional study of Active transcranial electrical vestibular stimulation (Active EVS) and Sham transcranial electrical vestibular stimulation (Sham EVS) in Vestibular Disorder, Vestibular Schwannoma and Vestibular Neuritis, sponsored by Aalto University. Enrolling by invitation at 1 site in Finland. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2026-07-01.
Sponsored by Aalto University · Not applicable, Interventional, and Diagnostic
The goal of this clinical trial is to preliminarily evaluate the use of electrical stimulation in diagnosing disorders with the vestibular system. The main questions it aims to answer are:
The participants will each attend one experimental session consisting of multiple short (1-3 min) measurement trials. During a trial the participant's vestibular system is stimulated with a transcranial electrical stimulator device and their movements are recorded with a force plate and acceleration sensors.
The goal of the study is to collect and analyse data from 30 research participants with diagnosed vestibular disorders.
170 studies on the registry are indexed under Vestibular Diseases; 41 are open to participants now.
This study's planned enrollment of 30 is below the median of 46 across 127 interventional studies indexed under Vestibular Diseases.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The study composes of multiple interventions (1-3 min electrical vestibular stimulation and response measurement). All study participants will get the same interventions but in different randomized order.
Device: Active transcranial electrical vestibular stimulation (Active EVS) · Device: Sham transcranial electrical vestibular stimulation (Sham EVS) · Device: Control measurement
Active transcranial electrical vestibular stimulation (EVS) with alternating current (maximum peak current below 2 mA and stimulation frequency 2-20 Hz) applied for 1-3 minutes at a time and for under 20 minutes in total. EVS will be applied either bilaterally (ear to ear) or unilaterally (left ear to neck or right ear to neck). The participants movements during the stimulation are measured with a force plate and wearable acceleration sensors. The study uses multiple types of vestibular stimulation waveforms which are applied in a randomized sequence, such that neither the participant nor the investigator know the exact stimulation type at the time of the measurement.
Sham (no current) transcranial electrical vestibular stimulation applied for 1-3 minutes. The participant's movements during the supposed stimulation are measured with a force plate and wearable acceleration sensors. Neither the participant nor the investigator know at what point of the intervention sequence the sham stimulation is applied.
The participant's movements are measured with a force plate and wearable acceleration sensors for the same time duration (1-3 min) and following the same protocols as in other interventions, but both the participant and the investigator know that no stimulation is being applied. The control measurement will always be completed before all other interventions and is not part of the randomized intervention sequence.
Changes in the frequency content of the movement response signals
Changes of the power in a frequency band of 0-20 Hz in the measured movement response signals during active electrical vestibular stimulation (EVS). The measured movement response signals are force plate Center of Pressure (CoP) and 3-axis acceleration data from wearable acceleration sensors.
Time frame: From study appointment to the analysis of the results (up to 12 months)
Latency of the EVS response
Latency of the EVS-induced movement response measured as the time delay between the stimulation and the measured movement.
Time frame: From study appointment to the analysis of the results (up to 12 months)
Highest frequency of the EVS-induced response
Highest frequency at which EVS induces a response determined via spectral analysis of the movement data
Time frame: From study appointment to the analysis of the results (up to 12 months)

Started Jun 2026 (actual). Primary completion is estimated for Dec 2027, 18 months after the start.
Of 79 non-industry interventional studies with no phase under Vestibular Diseases, half reached primary completion within 16 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 37. This study's planned 18 months is above that.
Counting every sponsor, half of 84 studies reached it within 15 months; a quarter within 8 and three quarters within 34.
