About this trial

This study investigates the effect of virtual reality (VR) motor tasks on functional movement disorders.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

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

Disqualifiers

unclear tremor syndrome

essential tremor plus (ET plus)

conditions that interfere with EEG diagnostic (skin conditions, skin infections, wounds)

reflex epilepsy

Trial design

Design model

Parallel

Treatments tested in this trial

  • Virtual reality motor task

    Diagnostic test

    After a short practice task, participants perform motor tasks in a virtual reality environment. Reaction time is used to assess task performance.

Treatment groups

48 Participants
are divided into 3 treatment groups
Group A: Functional Movement DisorderExperimental treatment 1 intervention
Group B: Essential TremorExperimental treatment 1 intervention
Group C: Healthy ControlExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Task performance

Reaction time in processing the VR task, measured in seconds

Time frame
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

1

Tremor duration

Duration of tremor during the motor task, expressed as % of movement time (only in FT and ET)

Time frame
5 measurement points: tasks a, b, c, d; Approximately 2.5 hours
2

EEG

Changes in mu and beta event-related (de)synchronizations between motor tasks and right and left hemispheres

Time frame
10 measurement points: resting state before each motor task and during each motor task; Approximately 2.5 hours
3

Subjective tremor severity on a visual analogue scale (VAS)

Subjective tremor severity measured by a visual analogue scale (VAS) from 0 to 10 points, with higher scores indicating greater tremor severity

Time frame
6 measurement points: before and after each task; Approximately 2.5 hours
4

VR acceptance

Technology Usage Inventory (TUI): from 29 to 203 points, with higher scores indicating greater acceptance of technologies

Time frame
2 measurement points: before and after the VR examination, Approximately 2.5 hours
