Brief Summary:

Traumatic brain injury (TBI) is a health issue impacting athletes and no clinical treatment protocol, other than rest, is yet established. The efficacy of a treatment protocol relies on objective, physiological measures of brain function and ultimately a quantification of injury severity.

The present study aims to assess neurophysiological markers of auditory and visual measures of brain function using the NeuroCatch Platform and eye-tracking technology, respectively. The current gold standard of TBI evaluation, including cognitive and balance assessments, will also be captured.

Official Title: Assessing Neurophysiological Markers of Brain Function: Investigating Event-Related Potentials and Eye-Tracking Measures in Hockey Players
Actual Study Start Date : July 7, 2019
Estimated Primary Completion Date : September 30, 2020
Estimated Study Completion Date : September 30, 2020

Group/Cohort Intervention/treatment
hockey players

During each study visit, the participants will undergo the following procedures:

  • NeuroCatch Platform (NCP) assessment (only if participant meets NCP-specific criteria)
  • RightEye's eye-tracking battery
  • Highmark Interactive's EQ application
  • Cambridge Brain Science's neuropsychological tests
Device: NeuroCatch Platform (NCP)
The NCP plays a proprietary 6-minute auditory stimulus sequence of tones and words that elicit involuntary evoked responses in the brain. Tone stimuli elicit N100 and P300 responses, and spoken word pairs elicit N400 responses. The NCP proprietary software identifies the latency and amplitude (timing and size) of three selected ERPs. Latency and amplitude values are reported as empirical (measured) values.

Primary Outcome Measures :
  1. ERP response size [ Time Frame: 1 week ]
    amplitude in microvolts

  2. ERP response timing [ Time Frame: 1 week ]
    latency in milliseconds

  3. Eye-tracking: target accuracy [ Time Frame: 1 week ]
    distance in millimeters for each eye

  4. Eye-tracking: speed [ Time Frame: 1 week ]
    degrees per second

Secondary Outcome Measures :
  1. Cognitive tests [ Time Frame: 1 year ]
    Cognitive assessments will be captured using Cambridge Brain Sciences battery of neuropsychological tests (composite score) and Highmark Interactive's EQ app

  2. Balance [ Time Frame: 1 week ]
    Balance measured in seconds as captured by Highmark Interactive's EQ app

Other Outcome Measures:
  1. Trends between outcome measures and demographics will be explored [ Time Frame: 1 year ]
    Demographics include age, concussion history, and handedness
