PURPOSE To compare accelerational forces to the head in high school-level football, hockey, and soccer athletes. METHODS Acceleration of impact was measured within the helmet of high school hockey and football players during actual game play. A triaxial accelerometer was placed at the vertex of the helmet immediately adjacent to the players head. Peak(More)
PRIMARY OBJECTIVE To validate a QEEG algorithm on traumatic brain injury in an Emergency Department (ED) setting. METHODS AND PROCEDURES EEG data were collected from 105 patients with head injury (53 CT+ and 52 CT-) and 50 ED controls. Ten minutes of eyes closed resting EEG was collected from five frontal locations. A discriminant index of the probability(More)
BACKGROUND There is an urgent need for objective criteria adjunctive to standard clinical assessment of acute Traumatic Brain Injury (TBI). Details of the development of a quantitative index to identify structural brain injury based on brain electrical activity will be described. METHODS Acute closed head injured and normal patients (n=1470) were(More)
This study investigates the potential clinical utility in the emergency department (ED) of an index of brain electrical activity to identify intracranial hematomas. The relationship between this index and depth, size, and type of hematoma was explored. Ten minutes of brain electrical activity was recorded from a limited montage in 38 adult patients with(More)
PURPOSE Cognitive deficits observed in professional soccer players may be related to heading of a soccer ball. To assess the severity of a single instance of heading a soccer ball, this study experimentally and theoretically evaluated the linear and angular accelerations experienced by the human head during a frontal heading maneuver. METHODS(More)
UNLABELLED There is increasing concern that repetitive blows to the head, such as those from heading a soccer ball, can cause measurable cognitive impairment. Reducing acceleration of impact could reduce neurologic sequelae. OBJECTIVE To measure the effectiveness of four different types of soccer headgear in reducing the acceleration of impact. METHODS(More)
Spinal immobilization is one of the most commonly performed pre-hospital procedures. Little research has been done on the movement of the neck during immobilization and extrication. In this study we used a sophisticated infrared six-camera motion-capture system (Motion Analysis Corporation, Santa Rosa, CA), to study the motion of the neck and head during(More)
Rapid identification of traumatic intracranial hematomas following closed head injury represents a significant health care need because of the potentially life-threatening risk they present. This study demonstrates the clinical utility of an index of brain electrical activity used to identify intracranial hematomas in traumatic brain injury (TBI) presenting(More)
