Comment in: Clin J Sport Med. 2005 Sep;15(5):385; author reply 385; PMID: 16163001 Source
Clinical Journal of Sport Medicine. 14(1):13-7, 2004 Jan. Abstract
OBJECTIVE: To investigate the frequency of unreported concussion and estimate more accurately the overall rate of concussion in high school football players. DESIGN: Retrospective, confidential survey completed by all subjects at the end of the football season. SETTING AND PARTICIPANTS: A total of 1,532 varsity football players from 20 high schools in the Milwaukee, Wisconsin, area were surveyed. MAIN OUTCOME MEASUREMENTS: The structured survey assessed (1) number of concussions before the current season, (2) number of concussions sustained during the current season, (3) whether concussion during the current season was reported, (4) to whom concussion was reported, and (5) reasons for not reporting concussion. RESULTS: Of respondents, 29.9% reported a previous history of concussion, and 15.3% reported sustaining a concussion during the current football season; of those, 47.3% reported their injury. Concussions were reported most frequently to a certified athletic trainer (! 76.7% of reported injuries). The most common reasons for concussion not being reported included a player not thinking the injury was serious enough to warrant medical attention (66.4% of unreported injuries), motivation not to be withheld from competition (41.0%), and lack of awareness of probable concussion (36.1%). CONCLUSIONS: These findings reflect a higher prevalence of concussion in high school football players than previously reported in the literature. The ultimate concern associated with unreported concussion is an athlete's increased risk of cumulative or catastrophic effects from recurrent injury. Future prevention initiatives should focus on education to improve athlete awareness of the signs of concussion and potential risks of unreported injury. Publication Type Journal Article.

Comparison of reporting systems to determine concussion incidence in NCAA Division I collegiate football. Source
Clinical Journal of Sport Medicine. 13(2):93-5, 2003 Mar. Abstract
OBJECTIVE: To determine the incidence of concussion during the 2001 Division I-A college football season through utilization of the Internet. DESIGN: Prospective Internet survey. SETTING: Internet Web site. PARTICIPANTS: Head athletic trainers from Division I-A collegiate football programs. MAIN OUTCOME MEASURES: During the 2001-2002 football season, head athletic trainers from 87 Division I-A football programs agreed to use an Internet Web site to submit weekly data on the number of athlete exposures and concussions. RESULTS: A total of 373 concussions were reported over the course of a season in both practices and games combined. Of these concussions, 256 (68.6%) occurred during games, and 117 (31.4%) occurred during practice. The injury rate per 1,000 athletic exposures was 5.56 in games and 0.25 in practices. There were 230 grade 1 (61.7%), 134 grade 2 (35.9%), and 9 grade 3 (2.4%) concussions reported. There was a significant (p < 0.01) difference found between the to! tal concussion injury rate and game concussion injury rate when comparing the Internet and the NCAA injury data collection methods. CONCLUSIONS: The results of this study suggest an underreporting of concussions using the NCAA Injury Surveillance System and demonstrate that the Internet is a simple and effective tool for data collection.

Concussions among university football and soccer players. Source
Clinical Journal of Sport Medicine. 12(6):331-8, 2002 Nov. Abstract
OBJECTIVE: A study to examine the incidence and characteristics of concussions among Canadian university athletes during 1 full year of football and soccer participation. DESIGN: Retrospective survey. PARTICIPANTS: Three hundred eighty Canadian university football and 240 Canadian university soccer players reporting to 1999 fall training camp. Of these, 328 football and 201 soccer players returned a completed questionnaire. MAIN OUTCOME MEASURES: Based on self-reported symptoms, calculations were made to determine the number of concussions experienced during the previous full year of football or soccer participation, the duration of symptoms, the time for return to play, and any associated risk factors for concussions. RESULTS: Of all the athletes who returned completed questionnaires, 70.4% of the football players and 62.7% of the soccer players had experienced symptoms of a concussion during the previous year. Only 23.4% of the concussed football players and 19.8% of the! concussed soccer players realized they had suffered a concussion. More than one concussion was experienced by 84.6% of the concussed football players and 81.7% of the concussed soccer players. Examining symptom duration, 27.6% of all concussed football players and 18.8% of all concussed soccer players experienced symptoms for at least 1 day or longer. Tight end and defensive lineman were the positions most commonly affected in football, while goalies were the players most commonly affected in soccer. Variables that increased the odds of suffering a concussion during the previous year for football players included a history of a traumatic loss of consciousness or a recognized concussion in the past. Variables that increased the odds of suffering a concussion during the previous year for soccer players included a past history of a recognized concussion while playing soccer and being female. CONCLUSIONS: University football and soccer players seem to be experiencing a signifi! cant amount of concussions while participating in their respective spo rts. Variables that seem to increase the odds of suffering a concussion during the previous year for football and soccer players include a history of a recognized concussion. Despite being relatively common, symptoms of concussion may not be recognized by many players. Publication Type Comparative Study. Journal Article. Result <27> Unique Identifier 11753060 Status

Concussions among university football and soccer players: a pilot study. Source
Clinical Journal of Sport Medicine. 11(4):234-40, 2001 Oct. Abstract
OBJECTIVE: A pilot study to examine the incidence and characteristics of concussions for one season of university football and soccer. DESIGN: Retrospective survey. PARTICIPANTS: 60 football and 70 soccer players reporting to 1998 fall training camp. Of these, 44 football and 52 soccer players returned a completed questionnaire. MAIN OUTCOME MEASURES: Based on self-reported symptoms, calculations were made to determine the number of concussions experienced during the previous season, the duration of symptoms, the time for return to play and any associated risk factors for concussions. RESULTS: Of all the athletes who returned completed questionnaires, 34.1% of the football players and 46.2% of the soccer players had experienced symptoms of a concussion during the previous season. Only 16.7% of the concussed football players and 29.2% of the concussed soccer players realized they had suffered a concussion. All of the concussed football players and 75.0% of the concussed soc! cer players experienced more than one concussion during the season. The symptoms from the concussion lasted for at least 1 day in 28.6% of the football players and 18.1% of the soccer players. Variables that increased the odds of suffering a concussion during the previous season for football and soccer players included a past history of a recognized concussion. CONCLUSION: More university soccer players than football players may be experiencing sport related concussions. Variables that seem to increase the odds of suffering a concussion during the previous season for football and soccer players include a history of a recognized concussion. Despite being relatively common, many players may not recognize the symptoms of a concussion. Publication Type Comparative Study. Journal Article. Result <28> Unique Identifier 10695844 Status

Concussions during the 1997 Canadian Football League season. Source
Clinical Journal of Sport Medicine. 10(1):9-14, 2000 Jan. Abstract
OBJECTIVE: To examine the incidence and characteristics of concussions for one season in the Canadian Football League (CFL). DESIGN: Retrospective survey. PARTICIPANTS: 289 players reporting to CFL training camp. Of these, 154 players had played in the CFL during the 1997 season. MAIN OUTCOME MEASURES: Based on self-reported symptoms, calculations were made to determine the number of concussions experienced during the previous season, the duration of symptoms, the time for return to play after concussion, and any associated risk factors for concussions. RESULTS: Of all the athletes who played during the 1997 season, 44.8% experienced symptoms of a concussion. Only 18.8% of these concussed players recognized they had suffered a concussion. 69.6% of all concussed players experienced more than one episode. Symptoms lasted at least 1 day in 25.8% of cases. The odds of experiencing a concussion increased 13% with each game played. A past history of a loss of consciousness while! playing football and a recognized concussion while playing football were both associated with increased odds of experiencing a concussion during the 1997 season. CONCLUSION: Many players experienced a concussion during the 1997 CFL season, but the majority of these players may not have recognized that fact. Players need to be better informed about the symptoms and effects of concussions. Publication Type Journal Article. Result <29> Unique Identifier 9762485 Status

Rugby injuries to the cervical spine and spinal cord: a 10-year review. [Review] [23 refs] Source
Clinics in Sports Medicine. 17(1):195-206, 1998 Jan. Abstract
A 10-year review (1987-1996) of injuries sustained to the spine and spinal cord in rugby players with resultant paralysis has been undertaken. This article reviews that the incidence of serious rugby spine and spinal cord injuries in South Africa has increased over the 10-year period reviewed, despite stringent new rules instituted in an attempt to decrease the incidence of these injuries. The mechanisms of injury, as previously reported, remain the same as well as the phases of game responsible for injury of the tight scrum, tackle, rucks, and mauls. Two new observations are reported: the first is related to the occurrence of spinal cord concussion with transient paralysis, and the second is related to the increased incidence of osteoarthritis of the cervical spine in rugby players.

Analysis of linear head accelerations from collegiate football impacts. Source
Current Sports Medicine Reports. 5(1):23-8, 2006 Feb. Abstract
Sports-related concussions result in 300,000 brain injuries in the United States each year. We conducted a study utilizing an in-helmet system that measures and records linear head accelerations to analyze head impacts in collegiate football. The Head Impact Telemetry (HIT) System is an in-helmet system with six spring-mounted accelerometers and an antenna that transmits data via radio frequency to a sideline receiver and laptop computer system. A total of 11,604 head impacts were recorded from the Virginia Tech football team throughout the 2003 and 2004 football seasons during 22 games and 62 practices from a total of 52 players. Although the incidence of injury data are limited, this study presents an extremely large data set from human head impacts that provides valuable insight into the lower limits of head acceleration that cause mild traumatic brain injuries.

An unusual presentation of a minor head injury sustained during a game of rugby. Source
Emergency Medicine Journal. 24(7):485-6, 2007 Jul. Abstract
In the UK, about 2% of the population attend the accident and emergency (A&E) department every year after a head injury. A majority of the patients have minor head injury and are discharged. Studies reveal that patients who reattend the A&E after a minor head injury represent a high-risk group. Concussion injuries are common and not all require treatment at the time of presentation. However, some may worsen after initial presentation and develop signs of serious head injury. A case of minor head injury as a result of head butt during a game of rugby, not associated with alteration in conscious state or focal neurological signs, and subsequent development of frontal lobe abscess a month later is reported. It is important that patients fit to be discharged at the time of consultation are discharged in the care of a responsible adult with clear head injury instruction sheets and are advised to return should their symptoms change. A high index of suspicion should be maintained! and an early imaging technique, such as CT scan should be considered in patients reattending the A&E with persistent symptoms even after minor head injury.

A proposed injury threshold for mild traumatic brain injury. Source
Journal of Biomechanical Engineering. 126(2):226-36, 2004 Apr. Abstract
Traumatic brain injuries constitute a significant portion of injury resulting from automotive collisions, motorcycle crashes, and sports collisions. Brain injuries not only represent a serious trauma for those involved but also place an enormous burden on society, often exacting a heavy economical, social, and emotional price. Development of intervention strategies to prevent or minimize these injuries requires a complete understanding of injury mechanisms, response and tolerance level. In this study, an attempt is made to delineate actual injury causation and establish a meaningful injury criterion through the use of the actual field accident data. Twenty-four head-to-head field collisions that occurred in professional football games were duplicated using a validated finite element human head model. The injury predictors and injury levels were analyzed based on resulting brain tissue responses and were correlated with the site and occurrence of mild traumatic brain injury! (MTBI). Predictions indicated that the shear stress around the brainstem region could be an injury predictor for concussion. Statistical analyses were performed to establish the new brain injury tolerance level. Publication Type Comparative Study. Evaluation Studies. Journal Article. Research Support, Non-U.S. Gov't.

Incidence of concussion in high school football players of Ohio and Pennsylvania. Source
Journal of Child Neurology. 16(2):83-5, 2001 Feb. Abstract
Football injuries account for more concussions than any other sport in North America. A 1977 survey of high school football players in Minnesota found that 19% of players reported at least one concussion (characterized by loss of awareness) during a season. These results have not been confirmed in subsequent studies. This study sought to estimate the incidence of concussion among high school football players in our region, establish the frequency of the most common symptoms, and determine the duration of subsequent restriction from participation in the sport. The athletic boards of area high schools distributed a three-page survey to 450 high school football players. Of the 450 surveys distributed, 234 (52%) were returned, only 1 of which was excluded because of contradictory information. The incidence of concussion in football players was 47.2% (110/233, P < .001 versus a previously determined rate of 19%). Eighty-one of 233 players (34.9%) had multiple concussions. A tot! al of 376 concussions were reported. The distribution of severity of the 376 reported concussive events was grade I, 87.8%; grade II, 9.9%; and grade III, 2.4%. Only 12 athletes were required to stop play for one or more games. The incidence of high school football players sustaining a concussion is much higher than previously established. The majority of these are mild (grade I) concussions. Further research is needed since multiple low-grade concussions may incur cumulative neuropsychologic impairments.

Cumulative concussion exposure in rugby players: neurocognitive and symptomatic outcomes. Source
Journal of Clinical & Experimental Neuropsychology: Official Journal of the International Neuropsychological Society. 30(4):398-409, 2008 May. Abstract
A total of 111 rugby players underwent comprehensive testing to determine the impact of self-reported concussion exposure. Reliable estimates of concussion exposure were associated with an increase in postconcussion symptoms (PCS), but not diminished neurocognitive functioning. Importantly, the effects of concussion exposure on PCS varied as a function of player status. More specifically, extent of concussion exposure was associated with increased memory complaints and overall PCS endorsements in a dose-dependent manner for retired and older recreational players, but not for those who were younger and playing at more competitive levels. Future work should systematically evaluate the constituent participant factors that may influence differential concussion outcomes. Publication Type Journal Article. Research Support, Non-U.S. Gov't.

Neuropsychological impairment as a consequence of football (soccer) play and football heading: preliminary analyses and report on university footballers. Source
Journal of Clinical & Experimental Neuropsychology: Official Journal of the International Neuropsychological Society. 27(3):299-319, 2005 Apr. Abstract
Previous research has claimed neuropsychological impairment occurs as a result of professional and amateur football play, and, specifically, football heading. However, much of this research exhibits substantial methodological problems. By investigating less committed amateur level footballers, the current study sought to gain some insight into the developmental history of any neuropsychological consequences of football play. University football, rugby and noncontact sports players were compared on a range of biographical and neuropsychological test variables. While playing their chosen sports, rugby players sustained many more head injuries than footballers and noncontact sportsmen, but footballers did not sustain significantly more head injuries than noncontact sportsmen. The number of head injuries sustained predicted Trails B and TAP Divided Attention latencies in a positive fashion. After controlling for the number of head injuries sustained, sport group effects were d! etected with TAP Divided Attention accuracy scores, with footballers exhibiting poorest performance. After controlling for the number of head injuries sustained, the total amount of heading done by footballers predicted the number of Wisconsin Card Sorting category shifts in a negative fashion. Nevertheless, over interpretation of all of these results should be resisted because of the exploratory nature of the analyses and the possibility that the sport groups may differ in ways other than just the nature of their sports activities.
