Details and patient eligibility

About

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:

• Can electrical vestibular stimulation combined with movement measurement be used to diagnose disorders of the vestibular system?
• Can electrical stimulation provide treatment or rehabilitation opportunities for patients suffering from disorders of the vestibular system?

Full description

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.

Enrollment: 30 estimated patients

Description:

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.

Treatment:

Device: Sham transcranial electrical vestibular stimulation (Sham EVS)

Device: Active transcranial electrical vestibular stimulation (Active EVS)

Device: Control measurement
