This systematic review screened 1,601 articles to compare existing sports-related concussion (SRC) definitions and evaluate biomechanical impact data. It was conducted in preparation for the 5th International Consensus Conference on Concussion in Sport (Berlin, 2016). The review produced the updated Berlin operational definition of SRC.
Before Berlin 2016, roughly 45 different concussion grading scales had been published, none validated — and six major organizations defined SRC differently, making consistent diagnosis and research nearly impossible.
The Berlin definition gives you a practical, clinically defensible framework: if an athlete takes a blow (direct or indirect), develops rapid-onset neurological symptoms reflecting functional disturbance, and has normal structural imaging, that is a concussion. Regardless of whether they lost consciousness.
When sideline decisions arise, do not rely on accelerometer data or helmet sensors alone to clear or pull a player. The paper explicitly states head acceleration data should not be used in isolation for return-to-play decisions.
Remember for boards and clinical practice: confusion and altered mental status, not LOC, are the hallmarks of concussion. A player who 'got their bell rung' without passing out still meets diagnostic criteria.
