With research showing nearly nine out of 10 concussions go undiagnosed every year, King-Devick Test Inc. developed a tablet that can detect concussions immediately after they are suspected. In collaboration with the Mayo Clinic ( the first licensing deal in Mayo’s 150-year history), the King-Devick test takes two minutes on the sidelines of an athletic contest. An injured athlete reads aloud single-digit numbers on three test cards, pre-injury and post-injury, and the results minimize guesswork in concussion testing when medical professionals are not present. A world leader in detecting reading disorders, King-Devick protects its test with 33 copyrights and eight patents pending.
