Concussion timeline

Michael G Hutchison, Lynda Mainwaring, Arrani Senthinathan, Nathan Churchill, Scott Thomas, Doug Richards
BACKGROUND: Sport-related concussions are associated with a range of physical, cognitive, and behavioral disturbances that are highly variable across individuals. Much remains unknown about the effects of sport concussion, and changes in markers of psychological and physiological stress over the recovery timeline. OBJECTIVE: To examine psychological (mood, stress, sleep quality, and symptoms) and physiological (heart rate variability and salivary cortisol) measures in concussed athletes over clinical recovery milestones...

There are an estimated 1.6 to 3.8 million sports and recreation-related concussions annually in the United States, with an average annual increase in incidence of 15.5% from 1998 to 2007. From 2009 to 2014, all 50 states enacted youth concussion legislation. This study clarifies core elements common to state concussion legislation and State Interscholastic Athletic Association (SIAA) implementation. A concussion literature, legislative, and SIAA concussion bylaw review was performed for all 50 U.S. states. Mandated concussion education varies in the frequency of certification and method of education...

The challenge and search for objectively based biomarkers to assess for the presence of concussion/mild traumatic brain injury is a high priority for the military establishment. We present a documented overview of specific test areas and related targeted, high-yield, objectively based parameters that may be potential "vision biomarkers" for the detection of concussion/mild traumatic brain injury based on results from our laboratory and others, with emphasis on oculomotor aspects. These findings have military relevance with respect to the initial diagnosis in the battlefield and in the far-forward medical facilities, pre-/postdeployment issues, pre-/postvisual rehabilitation evaluation, fitness-for-duty assessment, and establishment of a return-to-duty timeline...

Concussions in collegiate athletics can affect student-athletes both on the field and in the classroom. As policies are made to outline return-to-play decisions and timelines, this article will make the case that return-to-academics should also be included and follow a step-wise protocol. Complete cognitive rest is a cornerstone of concussion recovery and slow reintroduction to academics should precede return-to-play. The college structure allows for student-athletes to begin small doses of cognitive activity after the recommended complete cognitive rest...

CONTEXT: Whereas guidelines about return-to-play (RTP) after concussion have been published, actual prognoses remain elusive. OBJECTIVE: To develop probability estimates for time until RTP after sport-related concussion. DESIGN: Descriptive epidemiology study. SETTING: High school. PATIENTS OR OTHER PARTICIPANTS: Injured high school varsity, junior varsity, or freshman athletes who participated in 1 of 13 interscholastic sports at 7 area high schools during the 2007-2009 academic years...

This study aimed to determine if systematic variation of the diagnostic terminology embedded within written discharge information (i.e., concussion or mild traumatic brain injury, mTBI) would produce different expected symptoms and illness perceptions. We hypothesized that compared to concussion advice, mTBI advice would be associated with worse outcomes. Sixty-two volunteers with no history of brain injury or neurological disease were randomly allocated to one of two conditions in which they read a mTBI vignette followed by information that varied only by use of the embedded terms concussion (n = 28) or mTBI (n = 34)...

Biofeedback assisted self-regulation training can be an effective treatment for post-concussion headaches. The following is an example of using biofeedback assisted self-regulation training as an intervention to treat posttrauma headaches in a Special Operations Forces (SOF) support soldier. This Soldier was a 23-year-old male who had suffered a concussion while off duty four months earlier and continued to experience headache. Threemodality biofeedback (temperature, surface electromyogram and skin conduction) was used to help the patient learn to self-regulate and control his headaches...

BACKGROUND: Perception of illness plays an important role in recovery process. It affects our coping behaviors, adherence to treatment and preventive measures taken for healthy recovery. AIMS: The aim of the study is to examine perception of illness in patients with traumatic brain injury (TBI). MATERIALS AND METHODS: This was a cross sectional study design done on sample of 31 patients with mild to moderate TBI. Depression anxiety stress scales-21 (DASS-21), Brief illness perception questionnaire (IPQ) and Rivermead Post Concussion Symptoms Questionnaire (RPQ) was used...

CONTEXT: More than 1.6 million sport-related concussions occur every year in the United States, affecting greater than 5% of all high school athletes who participate in contact sports. As more females participate in sports, understanding possible differences in concussion symptoms between sexes becomes more important. OBJECTIVE: To compare symptoms, symptom resolution time, and time to return to sport between males and females with sport-related concussions. DESIGN: Descriptive epidemiology study...

OBJECTIVE: To assess predictive value of concussion signs and symptoms based on return-to-play timelines. DESIGN: Physician practice study without diagnosis that includes presentation, initial and subsequent treatment, and management of concussion. SETTING: National multisite primary care sports medicine provider locations. PARTICIPANTS: Twenty-two providers at 18 sites; 101 athletes (91 men, 10 women in the following sports: 73 football, 8 basketball, 8 soccer, 3 wrestling, 2 lacrosse, 2 skiing, 5 others; 51 college, 44 high school, 4 professional, and 2 recreational)...
