Understanding Head Injuries

ROSH Sensors do not prevent concussions and are not diagnostic. ROSH Sensors record the magnitude and location of a blow to the head. This information can be of importance as an extension of the clinical evaluation.


  • Concussion, or Mild Traumatic Brain Injury (MTBI) can occur as a result of a blow to the head
  • Concussions are difficult to diagnose because some symptoms may take days to appear
  • Diagnosis of concussion can only be made by a medical professional

Second Impact SYNDROME

  • SIS occurs when a person suffers a second concussion before symptoms from an earlier one have subsided
  • This second blow may occur minutes, days or weeks after an initial concussion
