Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Difference in mean baseline regional cerebral oxygen saturation as measured by near-infrared spectroscopy between children with mild traumatic brain injury and controls. [ Time Frame: At presentation (Day 0) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Difference in the change in regional cerebral oxygen saturation during handgrip exercise between children with mild traumatic brain injury and controls. [ Time Frame: At presentation (Day 0) ] [ Designated as safety issue: No ]
  • Difference in Sport Concussion Assessment Tool 2 (SCAT2) total score between patients with mild traumatic brain injury and controls. [ Time Frame: At presentation (Day 0) ] [ Designated as safety issue: No ]

Estimated Enrollment: 100

Study Population
This pilot study will employ a prospective cohort study design. Children aged 10-18 years will be recruited within the Johns Hopkins Hospital Pediatric Emergency Department (JHH PED) to participate in this study. All children must be conversant in English.


All Participants

  • Age 10-18 years at time of visit

Concussion Group

  • Present to JHH PED within the first 24 hours following trauma.
  • Diagnosis of concussion as defined by the 3rd International Conference on Concussion in Sport (McCrory), including the presence of any one or more of the following:

    1. Symptoms (ie. headache, neck pain, nausea/vomiting, dizziness, blurred vision, balance problems, sensitive to light, sensitivity to noise, feeling slowed down, feeling in a fog, difficulty concentrating, difficulty remembering, fatigue, confusion, drowsiness, more emotional, irritability, sadness, nervous)
    2. Physical Signs (ie. loss of consciousness, unsteadiness)
    3. Impaired brain function (ie. confusion)
  • Glasgow Coma Score of 13-15 upon arrival to JHH PED.
  • Loss of consciousness of less than 15 minutes (if applicable).
  • No structural intracranial injuries identified on neuroimaging (if completed).


All Participants

  • History of prior concussion or traumatic brain injury within preceding 6 weeks.
  • History of prior intracranial disease or mass (ie. tumor, intraventricular hemorrhage, etc.)
  • Presence of intracranial hardware.
  • Complaints of respiratory distress, tachypnea or hypoxia, which may affect regional cerebral oxygen saturation.
  • Inability to stand secondary to lower extremity disease or trauma, which is required for completion of SCAT2.
  • Inability to complete SCAT2 questionnaire secondary to developmental delay.
  • Child in foster care or legal guardian not available.
  • Participant known to be pregnant, which alters total body blood flow and likely affects regional cerebral oxygen saturation.
  • Non-English speaking.
