Context Temporal prediction of lower extremity (LE) injury risk will benefit clinicians by allowing them to better leverage limited resources and target athletes most at risk. Objective To characterize instantaneous risk of LE injury by demographic factors sex, sport, body mass index (BMI), and previous injury history. Instantaneous injury risk was defined as injury risk at any given point in time following baseline measurement. Design Descriptive epidemiology study. Setting NCAA Division I athletic program. Patients or Other Participants 278 NCAA Division I varsity student-athletes (119 males, 159 females). Main Outcome Measure(s) LE injuries were tracked for 237±235 days. Sex-stratified univariate Cox regression models investigated the association between time to first LE injury and BMI, sport, and previous LE injury history. Relative risk ratios and Kaplan-Meier curves were generated. Variables identified in the univariate analysis were included in a multivariate Cox regression m...
Predictors of lower extremity injuries in team sports (PROFITS-study): a study protocol
Introduction: Several intrinsic risk factors for lower extremity injuries have been proposed, including lack of proper knee and body control during landings and cutting manoeuvres, low muscular strength, reduced balance and increased ligament laxity, but there are still many unanswered questions. The overall aim of this research project is to investigate anatomical, biomechanical, neuromuscular, genetic and demographic risk factors for traumatic non-contact lower extremity injuries in young team sport athletes. Furthermore, the research project aims to develop clinically oriented screening tools for predicting future injury risk.
Rates and Patterns of Lower Extremity Sports Injuries in All Gender-Comparable US High School Sports
Orthopaedic Journal of Sports Medicine, 2019
Background: High school athletes with lower extremity sports injuries (LESIs) frequently present to the emergency department in the United States. Previous epidemiological studies have presented rates and mechanisms of LESIs in these athletes. No studies, however, have looked at LESIs in gender-comparable sports in an attempt to evaluate what differences exist between LESIs in boys and girls. Purpose: To describe the epidemiology of LESIs among US high school athletes using a large national database of athletes in sports that could be considered gender comparable, given the rules of play and protective equipment. Study Design: Descriptive epidemiology study. Methods: Descriptive data from 2005 to 2016 were collected using the internet-based High School Reporting Information Online (High School RIO), a national high school sports injury surveillance system, for athletes participating in 8 gender-comparable sports (soccer, volleyball, basketball, baseball/softball, swimming and diving...
Analyzing injuries among university-level athletes: prevalence, patterns and risk factors
The Journal of the Canadian Chiropractic Association, 2017
Scientific evidence suggests many health benefits are associated with sport participation. However, high intensity participation may be related to an increased risk of musculoskeletal injuries. This study aims to: 1) describe the prevalence and patterns of sports injuries, and 2) identify its associated risk factors. A cross-sectional design was used. University level athletes, involved in 7 sport disciplines reported musculoskeletal injuries sustained in the past year, as well as potential risk factors: training volume and antecedent sport participation. Group comparisons were conducted. 82 athletes participated in the study. Respondents sustained over two injuries per year. Significant differences were found for sport category and type of injury. No differences were observed regarding antecedent sport participation. High prevalence and sport-specific injuries observed in university sport should be of concern to athletes, therapists, coaches and sport organizers. This study contrib...

ABSTRACTIntroductionAthletics is a sport based on natural patterns and activities. As a sport, presents an array of benefices such as the improvement of physical condition and personal interaction, however, is not free of risks such as injuries related to training and competition.ObjectivesAnalyze the physical profile and associated sports injuries in an athletics college team.MethodsSubjects enrolled in a medicine college athletics team from Jan to Oct of 2021 of both genders had their characteristics collected and answered to a survey modified from the “NCAA Injury Surveillance System”.Results31 subjects answer the survey. 65% of the subjects present at least 1 injury, 73.9% of injuries were classified as severe, 0.27 injuries were reported per 1000 hours of exposure. Injured athletes had a practice time 2-fold greater than uninjured athletes. Quadriceps and shin injuries represent 52.17% of the injuries.ConclusionCollege athletics seems to present a high risk of severe sports inj...
A Prospective Study of Injury Incidence among North Carolina High School Athletes
American Journal of Epidemiology, 2006
Sports-related injuries are an issue of concern in high school sports athletes. A prospective cohort study of injury risk factors was conducted from 1996 to 1999 among varsity high school athletes in 12 sports in 100 North Carolina high schools. Data were collected by trained school personnel. Unadjusted and adjusted incidence rates and rate ratios were estimated using Poisson regression models. The overall rate of injury was 2.08 per 1,000 athleteexposures (95% confidence interval (CI): 1.79, 2.41). At 3.54 per 1,000 athlete-exposures (95% CI: 2.87, 4.37), football had the highest rate of injury of all sports. The adjusted rate ratio for athletes with a history of injury, compared with those without a prior injury, was 1.94 (95% CI: 1.69, 2.22). The injury rate rose with each year of playing experience (rate ratio ¼ 1.06, 95% CI: 1.01, 1.12). In a subanalysis restricted to gender-comparable sports, boys had a higher rate of injury than did girls (rate ratio ¼ 1.33, 95% CI: 0.99, 1.79). All other factors did not appear to be independent predictors of the injury rate. The influence of prior injury suggests that proper rehabilitation and primary prevention of the initial injury are important strategies for injury control. athletic injuries; incidence; prospective studies; risk; sports; wounds and injuries Abbreviations: CI, confidence interval; NCHSAA, North Carolina High School Athletic Association; RR, incidence rate ratio. More than seven million students in the United States participated in interscholastic high school athletics during the 2004-2005 school year, representing 53.4 percent of all high school students (1, 2). Historically, participation is at the highest level since record keeping began more than 30 years ago (1, 2). There are numerous health benefits associated with participation in sports (3, 4); however, injury is a potential outcome of participation and an important public health problem (5). Sport-and recreation-related injuries account for 46.4 percent of emergency department visits among adolescents aged 15-19 years (6).
Clinical Journal of Sport Medicine, 2017
Background: Growing evidence suggests that concussion increases the risk of lower extremity (LE) musculoskeletal injury. However, it is unclear to how the effect of concussion on LE injury risk may be influenced by previous injuries. This study sought to examine the association between concussion, previous LE injuries, and the risk LE injury to the same previously injured limb (ipsilateral) or the opposite limb (contralateral). Methods: This retrospective study examined medical records from 110 concussed athletes and 110 matched controls for LE injuries in the 365 days before and after the concussion event. The effect of concussion on time to injury was assessed with a Cox proportional hazard model after adjusting for injury history. Fine and Gray subdistribution models assessed the cumulative risk of ipsilateral and contralateral injury by group. Results: Concussion was associated with an increased instantaneous relative risk of LE injury when adjusting for LE injury history [hazard ratio (HR) 5 1.67, 95% confidence interval (CI) 5 1.11-2.53], agreeing with previous results. Among individuals who had a history of LE injuries before the concussion event, a nonsignificant yet moderate effect of concussion on the instantaneous relative risk of ipsilateral injuries was found after adjusting for the competing risk of contralateral injuries and censored values (HR 5 1.85, 95% CI 5 0.76-4.46). Conclusions: This study provides independent confirmation of previous studies, reporting an association between concussion and LE injury risk. Furthermore, this study suggests that future large-scale studies should consider the competing risk of ipsilateral, contralateral, and new injuries in populations with an injury history.
Lower extremity functional tests and risk of injury in division iii collegiate athletes
Purpose/Background: Functional tests have been used primarily to assess an athlete's fitness or readiness to return to sport. The purpose of this prospective cohort study was to determine the ability of the standing long jump (SLJ) test, the single-leg hop (SLH) for distance test, and the lower extremity functional test (LEFT) as preseason screening tools to identify collegiate athletes who may be at increased risk for a time-loss sports-related low back or lower extremity injury. Methods: A total of 193 Division III athletes from 15 university teams (110 females, age 19.1 ± 1.1 y; 83 males, age 19.5 ± 1.3 y) were tested prior to their sports seasons. Athletes performed the functional tests in the following sequence: SLJ, SLH, LEFT. The athletes were then prospectively followed during their sports season for occurrence of low back or LE injury. Results: Female athletes who completed the LEFT in Ն118 s were 6 times more likely (OR=6.4, 95% CI: 1.3, 31.7) to sustain a thigh or knee injury. Male athletes who completed the LEFT in Յ100 s were more likely to experience a time-loss injury to the low back or LE (OR=3.2, 95% CI: 1.1, 9.5) or a foot or ankle injury (OR=6.7, 95% CI: 1.5, 29.7) than male athletes who completed the LEFT in 101 s or more. Female athletes with a greater than 10% side-to-side asymmetry between SLH distances had a 4-fold increase in foot or ankle injury (cut point: >10%; OR=4.4, 95% CI: 1.2, 15.4). Male athletes with SLH distances (either leg) at least 75% of their height had at least a 3-fold increase (OR=3.6, 95% CI: 1.2, 11.2 for the right LE; OR=3.6, 95% CI: 1.2, 11.2 for left LE) in low back or LE injury. Conclusions: The LEFT and the SLH tests appear useful in identifying Division III athletes at risk for a low back or lower extremity sports injury. Thus, these tests warrant further consideration as preparticipatory screening examination tools for sport injury in this population. Clinical Relevance: The single-leg hop for distance and the lower extremity functional test, when administered to Division III athletes during the preseason, may help identify those at risk for a time-loss low back or lower extremity injury.
