Measuring Vestibular Organ Function With Weak Alternating Current Stimulation

Measuring Vestibular Organ Function With Weak Alternating-current Stimulation

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?

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.

Inclusion Criteria:

• Signed informed consent form
• One of the following: clinically diagnosed vestibular schwannoma, vestibular neuritis, or simultaneous unilateral hearing loss and vestibular dysfunction.

Exclusion Criteria:

• History of epilepsy or seizures
• Past brain surgery
• Pacemaker, cochlear implant, or other implanted medical device
• Pregnancy
• Skin problems or damaged skin at the site of the stimulation (scalp and neck)
