Chronic Traumatic Encephalopathy (CTE)

Routine exposure to head impacts has a clear link to a degenerative brain disease called CTE.  By increasing awareness of impacts, and avoiding having two sucessive impacts, ROSH Sensors help to avoid CTE. 

Second Impact Syndrome (SIS)

Second Impact Syndrome or SIS is a very rare condition in which a second concussion occurs before a first concussion has properly healed. This causes a rapid and severe brain swelling and often catastrophic results. Second impact syndrome can result from even a very mild concussion that occurs days or weeks after the initial concussion.


  • 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

How To Identify With Concussions and Avoid Second Impact Syndrome (SIS)


The ROSH Sensors register the blunt force based on the g-force on impact. BY having this instant record of the instance, a coach or player can willfully identify with their status and the avoidance of second impact syndrome (SIS).
