A recent study investigated the potential of a new sign, spontaneous headshake after a kinematic event (SHAAKE), to diagnose concussions in athletes. Concussions are mild brain injuries that can have serious consequences if not diagnosed promptly. SHAAKE was observed in nearly 73% of athletes after a collision, with common reasons being disorientation, dizziness, and a need to jumpstart the brain. The study found that SHAAKE had a sensitivity of 49.6% and a positive predictive value of 72.4% for diagnosing concussions across all sports, with higher sensitivity in football players. The researchers suggest incorporating SHAAKE into concussion protocols for improved diagnosis.
