摘要:

ObjectiveTo identify an objective evaluation technique to guide return-to-play decisions following mild brain injury (MBI) using an agility task that incorporates cognitive and motor performance.DesignProspective, controlled, repeated measures study.SettingCollegiate athletic training facility.Participants84 athletes (25 male rugby players, 34 female rugby players, 25 male ice hockey players) from 3 intercollegiate club teams participated. 9 athletes who suffered MBI during their competitive seasons and 9 matched controls completed the entire study protocol.Main Outcome MeasuresTime to complete an agility task on the Cybex Reactor and a postconcussive symptoms scale score were assessed in all subjects during the preseason. Injured subjects and matched controls were also assessed 1, 3, 5, and 10 days postinjury.ResultsRepeated measures analyses of variance revealed significant differences between injured subjects and controls in postconcussion symptoms, but not agility performance. Post hoc testing revealed that injured subjects reported significantly more postconcussion symptoms on Day 1 after injury.ConclusionThe methods of agility assessment used in this study appear to not be sensitive enough to detect functional impairment following MBI.

摘要:

ObjectiveTo describe the baseline characteristics of participants starting a 25-week marathon training program, and their relationship to injury risk factors.DesignProspective survey.SettingCommunity-based marathon training program.Participants1,548 of 2,314 registrants for the Houston Fit Marathon Training Program (mean age 35.8 ± 9.3 years, mean body mass index 24.3 ± 3.9, 63% female).Intervention4-page survey administered at registration.Main Outcome MeasureRunning experience, training practices, demographics, chronic medical problems and previous injuries.ResultsFemales were more likely to be classified as underweight and males as overweight or obese (p < 0.0001). The mean number of years of running experience was 6.2 ± 6.2. Most (87.5%) planned to train at a 9-minute mile or slower pace. 52.3% of the participants had not previously trained for a marathon. In the 3 months prior to starting the program 16.1% had been sedentary. Those runners who had not previously completed a marathon and not previously trained with Houston Fit had a higher prevalence of baseline training techniques that could be risk factors for injury. During the previous 3 years, 38.1% reported having an injury, and 35% of all injuries were still symptomatic at the start of the program.ConclusionsTraining programs for the marathon attract more female athletes and those with less running and marathon experience. The prevalence of being overweight or obese is 35.6%. 16.1% are sedentary during the 3 months before starting this program. Training programs must take measures to establish baseline fitness, to educate on injury prevention training techniques, and to set appropriate fitness goals.Clinical RelevanceThe research study shows that many patients wanting to start a marathon training program are relatively untrained and inexperienced with reference to endurance running. These patients will need special care and education so as to minimize injury and maximize the effect on their physical activity habits.

摘要:

ObjectiveTo determine the prevalence of eye injuries among intercollegiate women's lacrosse players as well as the level of play, specific play settings, and particular mechanisms associated with these injuries.DesignAnonymous, retrospective, survey.SettingIntercollegiate lacrosse tournament.ParticipantsCollegiate and postcollegiate women's lacrosse players.Main Outcome MeasuresSelf-reports of eye injuries, injury circumstances, treatment received, playing time missed, and continuing problems were recorded.ResultsSurveys were collected from 667 players from 34 teams (83% of players listed on rosters). A total of 125 injuries were reported among 84 players (12.6%). Injuries occurred equally in high school and college. Athletes were injured most frequently in games (41 injuries) and practices (38 injuries), with 17 players injured during the off-season. Several mechanisms of injury were noted. Fifty-three women sustained injuries requiring medical attention. Of those athletes injured, 23 missed 1–5 days and 9 players missed more than 5 days. Four athletes (4.8%) reported residual problems from an eye injury sustained while playing lacrosse.ConclusionsEye injuries are occurring more frequently than current surveillance data suggest. Because injuries are seen at all levels of play, in many different situations, and by multiple mechanisms, mandatory eyewear is needed to prevent serious eye injuries in women's lacrosse.

摘要:

ObjectivesTo document injury rates, severity, and relative risk during five competitive seasons of Canadian professional rodeo, between experienced (saddle bronc [SB], bareback [BB], and bull riders [BR]) and inexperienced (novice saddle bronc [NSB], novice bareback [NBB], and boys' steer riders [BSR]) rough stock competitors.DesignProspective cohort study.SettingCanadian professional rodeo competition.SubjectsExperienced competitors included professional cowboys from Australia, Brazil, New Zealand, the United States, and Canada. Inexperienced competitors included cowboys from Canada and the United States.MethodsData was gathered prospectively at 63 of 323 professional rodeos in Canada from 1995 to 1999, constituting 30.8% of all professional rodeo performances during this time period. Injury data (severity and body part affected) was included when the injury occurred to a registered contestant, at a Canadian professional rodeo, at which the Canadian Professional Rodeo Sport Medicine Team was officially present and providing services. Data were collected by certified athletic therapists.Main ResultsInexperienced rough stock competitors had a lower overall rate of injury in comparison to experienced competitors. In addition, inexperienced rough stock competitors had a lower injury rate of severe injuries, and a lower rate of injury to most body parts when compared with experienced competitors. Inexperienced competitors had a high rate of injury to the hand, wrist, and forearm. Most of these injuries to inexperienced contestants occurred to NBB (46%) and BSRs (31%). The relative risk of injury to inexperienced competitors did not differ from experienced competitors in the horse riding events (NSB vs. SB, NBB vs. BB), but the relative risk of injury to BSRs was one-half that of BR (0.49).ConclusionsInexperienced competitors in rodeo rough stock events do not have increased rates of severe injury, or of injury to specific body parts (in general). Inexperienced competitors do have a greater rate of injury to the arm, hand, and wrist. The relative risk of BSR is one-half the risk of BR.
