  • dynamic balance performance and noncontact Lower Extremity Injury in college football players an initial study
    Sports Health: A Multidisciplinary Approach, 2013
    Co-Authors: Robert J Butler, Michael E Lehr, Michael L Fink, Kyle B Kiesel, Phillip J Plisky
    Abstract:

    BACKGROUND: Field expedient screening tools that can identify individuals at an elevated risk for Injury are needed to minimize time loss in American football players. Previous research has suggested that poor dynamic balance may be associated with an elevated risk for Injury in athletes; however, this has yet to be examined in college football players. HYPOTHESIS: To determine if dynamic balance deficits are associated with an elevated risk of Injury in collegiate football players. It was hypothesized that football players with Lower performance and increased asymmetry in dynamic balance would be at an elevated risk for sustaining a noncontact Lower Extremity Injury. STUDY DESIGN: Prospective cohort study. METHODS: Fifty-nine collegiate American football players volunteered for this study. Demographic information, Injury history, and dynamic balance testing performance were collected, and noncontact Lower Extremity injuries were recorded over the course of the season. Receiver operator characteristic curves were calculated based on performance on the Star Excursion Balance Test (SEBT), including composite score and asymmetry, to determine the population-specific risk cut-off point. Relative risk was then calculated based on these variables, as well as previous Injury. RESULTS: A cut-off point of 89.6% composite score on the SEBT optimized the sensitivity (100%) and specificity (71.7%). A college football player who scored below 89.6% was 3.5 times more likely to get injured. CONCLUSION: Poor performance on the SEBT may be related to an increased risk for sustaining a noncontact Lower Extremity Injury over the course of a competitive American football season. CLINICAL RELEVANCE: College football players should be screened preseason using the SEBT to identify those at an elevated risk for Injury based upon dynamic balance performance to implement Injury mitigation strategies to this specific subgroup of athletes.

  • field expedient screening and Injury risk algorithm categories as predictors of noncontact Lower Extremity Injury
    Scandinavian Journal of Medicine & Science in Sports, 2013
    Co-Authors: Michael E Lehr, Robert J Butler, Michael L Fink, Kyle B Kiesel, Phillip J Plisky, Frank B Underwood
    Abstract:

    In athletics, efficient screening tools are sought to curb the rising number of noncontact injuries and associated health care costs. The authors hypothesized that an Injury prediction algorithm that incorporates movement screening performance, demographic information, and Injury history can accurately categorize risk of noncontact Lower Extremity (LE) Injury. One hundred eighty-three collegiate athletes were screened during the preseason. The test scores and demographic information were entered into an Injury prediction algorithm that weighted the evidence-based risk factors. Athletes were then prospectively followed for noncontact LE Injury. Subsequent analysis collapsed the groupings into two risk categories: Low (normal and slight) and High (moderate and substantial). Using these groups and noncontact LE injuries, relative risk (RR), sensitivity, specificity, and likelihood ratios were calculated. Forty-two subjects sustained a noncontact LE Injury over the course of the study. Athletes identified as High Risk (n = 63) were at a greater risk of noncontact LE Injury (27/63) during the season [RR: 3.4 95% confidence interval 2.0 to 6.0]. These results suggest that an Injury prediction algorithm composed of performance on efficient, low-cost, field-ready tests can help identify individuals at elevated risk of noncontact LE Injury.

  • using the star excursion balance test to assess dynamic postural control deficits and outcomes in Lower Extremity Injury a literature and systematic review
    Journal of Athletic Training, 2012
    Co-Authors: Phillip A Gribble, Jay Hertel, Phillip J Plisky
    Abstract:

    Context: A dynamic postural-control task that has gained notoriety in the clinical and research settings is the Star Excursion Balance Test (SEBT). Researchers have suggested that, with appropriate instruction and practice by the individual and normalization of the reaching distances, the SEBT can be used to provide objective measures to differentiate deficits and improvements in dynamic postural-control related to Lower Extremity Injury and induced fatigue, and it has the potential to predict Lower Extremity Injury. However, no one has reviewed this body of literature to determine the usefulness of the SEBT in clinical applications. Objective: To provide a narrative review of the SEBT and its implementation and the known contributions to task performance and to systematically review the associated literature to address the SEBT's usefulness as a clinical tool for the quantification of dynamic postural-control deficits from Lower Extremity impairment. Data Sources: Databases used to locate peer-reviewed a...

    Journal of Athletic Training, 2017
    Co-Authors: Robert C. Lynall, Zachary Y Kerr, Ryan T Pohlig, Thomas P Dompier, Timothy C. Mauntel, Eric E Hall, Thomas A Buckley
    Abstract:

    Context:  Although an association between concussion and musculoskeletal Injury has been described in collegiate and professional athletes, no researchers have investigated an association in younger athletes. Objective:  To determine if concussion in high school athletes increased the risk for Lower Extremity musculoskeletal Injury after return to activity. Design:  Observational cohort study. Setting:  One hundred ninety-six high schools across 26 states. Patients or Other Participants:  We used data from the National Athletic Treatment, Injury and Outcomes Network surveillance system. Athletic trainers provided information about sport-related concussions and musculoskeletal injuries in athletes in 27 sports, along with missed activity time due to these injuries. Main Outcome Measure(s):  Three general estimating equations were modeled to predict the odds of sustaining (1) any Lower Extremity Injury, (2) a time-loss Lower Extremity Injury, or (3) a non–time-loss Lower Extremity Injury after concussion. P...

    Journal of Athletic Training, 2017
    Co-Authors: Robert C. Lynall, Zachary Y Kerr, Timothy C. Mauntel, Jason P Mihalik, Brian Pietrosimone, Kevin M Guskiewicz
    Abstract:

    Context:  Dynamic balance deficits have been described postconcussion, even after athletes return to play. Lower Extremity (LE) musculoskeletal Injury rates increase for up to 1 year after concussion, but the long-term musculoskeletal implications of concussion are unclear. Objective:  To (1) examine the association of concussion and LE Injury histories with osteoarthritis (OA) prevalence in retired National Football League players and (2) examine the association of concussion and LE Injury histories with OA prevalence in those ≤55 years of age. Design:  Case-control study. Setting:  Survey. Patients or Other Participants:  We administered the Health Survey of Retired National Football League Players, which collects information about demographics, OA, LE Injury, and concussion history. Main Outcome Measure(s):  Twelve discrete categories were created based on concussion and LE Injury history, ranging from 0 concussions and 0 LE injuries (referent group) to 3+ concussions and 2+ LE injuries. Binomial regre...

  • acute Lower Extremity Injury rates increase after concussion in college athletes
    Medicine and Science in Sports and Exercise, 2015
    Co-Authors: Robert C. Lynall, Timothy C. Mauntel, Darin A. Padua, Jason P Mihalik
    Abstract:

    AB Dynamic postural control deficits and disrupted cortical pathways have been reported to persist beyond an athlete's return to activity after concussion, potentially increasing the risk of acute Lower Extremity musculoskeletal Injury. Purpose: This study aimed to investigate acute Lower Extremity musculoskeletal Injury rates before and after concussion in athletes with concussion and their matched control. Methods: College athletes with concussion (n = 44; age, 20.0 +/- 1.2 yr) were physician-diagnosed. Nonconcussed college athletes (n = 58; age, 20.5 +/- 1.3 yr) were matched to individuals with concussion. Acute Lower Extremity musculoskeletal Injury data were collected for 2 yr (+/-1 yr of the diagnosed concussion) using electronic medical records. Control participants' 2-yr window for exposure and musculoskeletal Injury data were anchored to their match's concussion Injury date. Pre- and postconcussion musculoskeletal Injury rates were calculated for 90-, 180-, and 365-d periods for both study cohorts. Risk ratios were calculated to determine differences within and between groups for all periods. Results: Within 1 yr after concussion, the group with concussion was 1.97 (95% confidence interval (CI), 1.19-3.28; P = 0.01) times more likely to have experienced an acute Lower Extremity musculoskeletal Injury after concussion than before concussion and 1.64 times (95% CI, 1.07-2.51; P = 0.02) more likely to have experienced an acute Lower Extremity musculoskeletal Injury after concussion than their matched nonconcussed cohort over the same period. Up to 180 d after concussion, the group with concussion was 2.02 (95% CI, 1.08-3.78; P = 0.02) times more likely to have experienced an acute Lower Extremity musculoskeletal Injury after concussion than before concussion. Conclusions: Previous literature has identified dynamic postural control deficits along with increased motor evoked potential latency and decreased amplitude after concussion, suggesting that the brain may be unable to effectively coordinate movement. Our findings underscore the need to explore functional movement and dynamic postural control assessments in postconcussion Injury assessment protocols.

  • increasing Lower Extremity Injury rates across the 2009 2010 to 2014 2015 seasons of national collegiate athletic association football an unintended consequence of the targeting rule used to prevent concussions
    American Journal of Sports Medicine, 2016
    Co-Authors: Robert W Westermann, Zachary Y Kerr, Peter Wehr, Annuziato Amendola
    Abstract:

    Background:Sports-related concussions (SRCs) have gained increased societal interest in the past decade. The National Collegiate Athletic Association (NCAA) has implemented legislation and rule changes to decrease the incidence and risk of head Injury impacts. The “targeting” rule forbids initiating contact with the crown of a helmet and targeting defenseless players in the head and neck area; however, there are concerns that this rule change has unintentionally led to an increased incidence of Lower Extremity injuries.Purpose/Hypothesis:The purpose of this study was to evaluate the change in Lower Extremity Injury rates in NCAA football during the 2009-2010 to 2014-2015 seasons. We hypothesized that the Lower Extremity Injury rate has increased across the time period.Study Design:Descriptive epidemiology study.Methods:Sixty-eight NCAA football programs provided 153 team-seasons of data to the NCAA Injury Surveillance Program. Lower Extremity injuries (ie, hip/groin, upper leg/thigh, knee, Lower leg/Achil...
