King Devick Test in Mixed Martial Arts


About this study

This study will investigate sub-concussions, concussions, and pre-syncopal choking episodes in a number of fighters using King Devick Test (KDT). We will also explore the immediate and long term consequence on the KDT results after a concussion or a pre-syncope have occurred.

The goal of our study is to validate KDT in Mixed martial arts (MMA), to propose the adoption of the KDT in the State of Minnesota to detect immediate cognitive decline during the amateur and pro-fighting event.
