Concussions can’t be detected by medical equipment so players who suffer head injuries need to take cognition tests that measure their pre- and post-injury abilities to determine whether they have suffered a concussion.
For example, using an iPad app created by C3 Logix, medical staff can test players for symptoms in a variety of areas including visual acuity and balance, and determine the severity of the concussion. Doctors can also use the iPad’s accelerometer and gyroscope to help test a player’s balance.
"In the past, it was easy to miss a concussion because of highly subjective reporting from athletes and errors made during paper-and-pencil data collection," Apple says in Your Verse post at its site. But using an iPad, athletic trainers like Jason Cruickshank can make injury assessments based on precise measurements.
“Using iPad with C3 Logix, we get hard, factual data that we can put in front of the athlete and say, ‘Look, this is where you should be.’”
Using the iPad to detect concussions isn’t new technology though. As 9to5Mac points out, Notre Dame has been using iPads since last year for just such a purpose and the NFL has given iPads to football teams to help with testing.
