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)
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)
BACKGROUND Diabetic ketoacidosis (DKA) is a common, life-threatening complication of diabetes. The diagnosis of DKA relies on signs and symptoms, plus laboratory findings of blood glucose (BG) of > 250 mg/dL, an anion gap (AG) of > or = 15 mmol/L, and carbon dioxide (CO2) of < or = 18 mmol/L when other causes of acidosis are excluded. OBJECTIVES To(More)
UNLABELLED Several recent studies suggest that acceleration of the head at impact during sporting activities may have a detrimental effect on cognitive function. Reducing acceleration of impact in these sports could reduce neurologic sequelae. OBJECTIVE To measure the effectiveness of a regulation football helmet to reduce acceleration of impact for both(More)
Controversy exists concerning the lethality of Tasers. These are conducted electrical weapons which incapacitate subjects by delivering an electrical charge that causes diffuse muscle contraction. In North America, over 440 deaths have been reported immediately following Taser use. Taser International has recently suggested that Tasers should not be aimed(More)
The purpose of this study was to assess whether greater operator confidence correlates with more accurate focused abdominal ultrasounds (FAUS) by residents. This was a prospective study of novice residents performing FAUS in patients with abdominal pain. FAUS included focused assessment with sonography for trauma, gall bladder, renal, and aortic(More)
OBJECTIVES The objective was to assess the incidence of various technical errors committed by emergency physicians (EPs) learning to perform focused assessment with sonography in trauma (FAST). METHODS This was a retrospective review of the first 75 consecutive FAST exams for each EP from April 2000 to June 2005. Exams were assessed for noninterpretable(More)
OBJECTIVES To assess whether 10 focused abdominal sonography for trauma (FAST) examinations could be used as a minimum standard for training, as suggested previously. METHODS This was a retrospective review of patients with abdominal trauma who underwent resident-performed FAST examinations before surgical or Department of Radiology evaluation. RESULTS(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)
OBJECTIVES (1) To test the validity of the Standardized Assessment of Concussion (SAC) in characterizing the early evolution of concussion-related symptoms and mental status changes in the emergency department (ED) setting and (2) to compare it to the Conner's Continuous Performance Test 2nd Edition (CPT-II). DESIGN Prospective within-subject (repeated(More)
