Outcome Measures
Primary Outcomes (1)
Task performance
Reaction time in processing the VR task, measured in seconds
4 measurement points: abstract hand model without time pressure, abstract hand model with time pressure, realistic hand model without time pressure, realistic hand model with time pressure. Approximately 2.5 hours
Secondary Outcomes (4)
Tremor duration
5 measurement points: tasks a, b, c, d; Approximately 2.5 hours
EEG
10 measurement points: resting state before each motor task and during each motor task; Approximately 2.5 hours
Subjective tremor severity on a visual analogue scale (VAS)
6 measurement points: before and after each task; Approximately 2.5 hours
VR acceptance
2 measurement points: before and after the VR examination, Approximately 2.5 hours
Study Arms (3)
Functional Movement Disorder
EXPERIMENTALEssential Tremor
EXPERIMENTALHealthy Control
EXPERIMENTALInterventions
After a short practice task, participants perform motor tasks in a virtual reality environment. Reaction time is used to assess task performance.
Eligibility Criteria
You may qualify if:
- diagnosis of functional tremor (FT) or essential tremor (ET) or healthy control persons
- In patients with FT and ET: presence of a constant or intermittent tremor during the neurological examination
You may not qualify if:
- unclear tremor syndrome
- essential tremor plus (ET plus)
- conditions that interfere with EEG diagnostic (skin conditions, skin infections, wounds)
- reflex epilepsy
- cervical degeneration or chronic pain syndrome of the cervical spine
- severe somatic illness
- previous cerebral or head surgery
- implanted pacemaker or deep brain stimulation
- persons who are unable to consent
