NCT06782360

Brief Summary

The goal of this clinical trial is to extend this period of optimal cognitive performance by applying neurostimulation to buffer health volunteers against the effects of increased levels of stress, distraction, and cybersickness. The main questions it aims to answer are:

  • Can we use OpenBCI's head-mounted Galea biosensor + eXtended Reality (XR) platform to measure participants' cognitive state in relation to stress, attention and cybersickness?
  • How does applying external neurostimulation via Spark Biomedical's Sparrow Link transcutaneous auricular neurostimulation (tAN) system enhance cognitive performance with a closed-loop interface that automatically applies neurostimulation as a function of physiologically determined stress, attention, and cybersickness metrics? Researchers will compare the active neurostimulation group to the sham neurostimulation group to see if cognitive performance is improved with stimulation. Participants will complete 4 virtual reality tasks in the lab:
  • 2 tasks related to attention - Flanker and Gradual-onset Continual Performance Task (GradCPT)
  • The Multi-Attribute Task Battery (MATB)
  • A cybersickness task
  • And a baseline session before each task
  • Neurostimulation intervention will occur in response to cognitive states

Outcome Measures

Primary Outcomes (4)

  • Flanker Task Performance

    Performance will be measured by number of correct responses and reaction time. Specially we will look at mean change in score (percentage of correct responses) and reduction in reaction time.

    Baseline, pre-intervention, and during the intervention phases

  • GradCPT Task Performance

    Performance will be measured by number of correct responses and reaction time. Specially we will look at mean change in score (percentage of correct responses) and reduction in reaction time.

    Baseline, pre-intervention, and during the intervention phases

  • MATB Task Performance

    Performance will be measured by number of correct responses and performance in the resource management task. Specially we will look at mean task completion percentage and root mean squared error in resource management task.

    Baseline, pre-intervention, and during the intervention phases

  • Cybersickness Task Performance

    Performance will be measured by time in experiment. Specifically we will look at mean time before cybersickness symptoms present and mean time before participants voluntarily discontinue the experiment.

    Baseline, pre-intervention, and during the intervention phases

Secondary Outcomes (3)

  • Bedford Work Scale Responses

    Baseline, pre-intervention, and during the intervention phases

  • Simulator Sickness Questionnaire (SSQ) Responses

    Baseline, pre-intervention, and during the intervention phases

  • Baxter Retching Faces (BARF) Responses

    Baseline, pre-intervention, and during the intervention phases

Study Arms (2)

Sham Stimulation

SHAM COMPARATOR

The sham group will receive a device but no stimulation will be delivered.

Device: Sham Stimulation

Active tAN

EXPERIMENTAL

This group receives active neurostimulation at different intervals, amplitudes, and frequencies via the Sparrow Link device.

Device: Active Neurostimulation

Interventions

The stimulation frequency, pulse width, and amplitude will be varied in order to determine the optimal stimulation conditions for elongating the period of peak subject performance during the experimental tasks. Amplitude, pulse width, and frequency meet or exceed International Electrotechnical Commission (IEC) 60601-2-10:2016 requirements. The amplitude range specified is selectable for either channel with any frequency and pulse width combination. We will test an amplitude range of 0 mA - 5.0 mA. We will test a frequency range of 1 Hz - 150 Hz. We will test a pulse width range of 50 μs - 750 μs. The study coordinator should apply neurostimulation when the reported cognitive state metric corresponding to the performance task reaches different thresholds. These thresholds will be determined before execution of the study and will be chosen to maximize the likelihood of discovering an optimal trigger for neurostimulation based on reported cognitive state.

Active tAN

Modulation of stimulation frequency and amplitudes outside of the known physiological effective ranges during intervention periods.

Sham Stimulation
