  • Effectiveness of an Exercise-Based Active Rehabilitation Intervention for
           Youth Who Are Slow to Recover After Concussion
    • Authors: Gauvin-Lepage; Jérôme; Friedman, Debbie; Grilli, Lisa; Sufrategui, Maria; De Matteo, Carol; Iverson, Grant L.; Gagnon, Isabelle
      Abstract: imageObjective: (1) To determine the impact of providing participants aged 8 to 17 years who are slow to recover after a concussion with a well-developed active rehabilitation intervention (ARI), compared with receiving standard care alone, on postconcussion symptoms (PCS) at 2 and 6 weeks after the initiation of ARI; and (2) to investigate functional recovery 6 weeks after initiation of ARI.Design: A multicenter prospective quasi-experimental control group design.Setting: Tertiary care pediatric trauma center and community health care providers.Participants: Forty-nine youth were enrolled (experimental n = 36; control n = 13).Procedures: Participants were assessed on 3 different occasions: (1) initial visit (baseline); (2) 2 weeks; and (3) 6 weeks after enrollment.Main Outcome Measures: Child- and parent-reported PCS were obtained by the PCS Inventory Scale (primary outcome). Secondary outcomes included: (1) mood and anxiety; (2) quality of life; (3) energy level; (4) coordination and balance; (5) neurocognition; (6) parental anxiety; and (7) satisfaction with intervention.Results: Both groups reported decrease of PCS over time (child: P = 0.01; parent: P = 0.03). Children in the experimental group presented higher quality of life (P = 0.04) and less anger (P = 0.02). A trend toward significance was observed for better tandem gait (P = 0.07) and for less general fatigue on self-reported PCS (P = 0.09) in the experimental group.Conclusions: Active rehabilitation intervention does not affect the PCS beyond the usual management, but it increases their quality of life, decreases anger, and potentially increases energy level and balance.

  • Eye Tracking as a Biomarker for Concussion in Children
    • Authors: Bin Zahid; Abdullah; Hubbard, Molly E.; Lockyer, Julia; Podolak, Olivia; Dammavalam, Vikalpa M.; Grady, Matthew; Nance, Michael; Scheiman, Mitchell; Samadani, Uzma; Master, Christina L.
      Abstract: imageObjective: Concussion is the most common type of brain injury in both pediatric and adult populations and can potentially result in persistent postconcussion symptoms. Objective assessment of physiologic “mild” traumatic brain injury in concussion patients remains challenging. This study evaluates an automated eye-tracking algorithm as a biomarker for concussion as defined by its symptoms and the clinical signs of convergence insufficiency and accommodation dysfunction in a pediatric population.Design: Cross-sectional case–control study.Setting: Primary care.Patients: Concussed children (N = 56; mean age = 13 years), evaluated at a mean of 22-week post-injury, compared with 83 uninjured controls.Independent Variables: Metrics comparing velocity and conjugacy of eye movements over time were obtained and were compared with the correlation between Acute Concussion Evaluation (ACE) scores, convergence, and accommodation dysfunction.Main Outcome Measures: Subjects' eye movements recorded with an automated eye tracker while they watched a 220-second cartoon film clip played continuously while moving within an aperture.Results: Twelve eye-tracking metrics were significantly different between concussed and nonconcussed children. A model to classify concussion as diagnosed by its symptoms assessed using the ACE achieved an area under the curve (AUC) = 0.854 (71.9% sensitivity, 84.4% specificity, a cross-validated AUC = 0.789). An eye-tracking model built to identify near point of convergence (NPC) disability achieved 95.8% specificity and 57.1% sensitivity for an AUC = 0.810. Reduced binocular amplitude of accommodation had a Spearman correlation of 0.752(P value

  • Reliability of Objective Eye-Tracking Measures Among Healthy Adolescent
    • Authors: Howell; David R.; Brilliant, Anna N.; Master, Christina L.; Meehan, William P. III
      Abstract: imageObjective: To determine the test–retest correlation of an objective eye-tracking device among uninjured youth athletes.Design: Repeated-measures study.Setting: Sports-medicine clinic.Participants: Healthy youth athletes (mean age = 14.6 ± 2.2 years; 39% women) completed a brief, automated, and objective eye-tracking assessment.Independent variables: Participants completed the eye-tracking assessment at 2 different testing sessions.Main outcome measures: During the assessment, participants watched a 220-second video clip while it moved around a computer monitor in a clockwise direction as an eye tracker recorded eye movements. We obtained 13 eye movement outcome variables and assessed correlations between the assessments made at the 2 time points using Spearman's Rho (rs).Results: Thirty-one participants completed the eye-tracking evaluation at 2 time points [median = 7 (interquartile range = 6–9) days between tests]. No significant differences in outcomes were found between the 2 testing times. Several eye movement variables demonstrated moderate to moderately high test–retest reliability. Combined eye conjugacy metric (BOX score, rs = 0.529, P = 0.008), the variance of the ratio for both eye movements in the horizontal (rs = 0.497, P = 0.013) and vertical (rs = 0.446; P = 0.029) movement planes along the top/bottom of the computer screen, and the variance of the left and right eye movement along the bottom segment of the computer screen (rs = 0.565; P = 0.004) each demonstrated moderate between-test correlations.Conclusions: Automated and quantitative eye movement and conjugacy metrics provide relatively stable measurements among a group of healthy youth athletes. Thus, their inclusion as a visual tracking metric may be complementary to other visual examination techniques when monitoring concussion recovery across time.

  • Sway Balance Mobile Application: Reliability, Acclimation, and Baseline
    • Authors: Mummareddy; Nishit; Brett, Benjamin L.; Yengo-Kahn, Aaron M.; Solomon, Gary S.; Zuckerman, Scott L.
      Abstract: imageObjectives: To describe historic baseline session administration practices, to assess the utility of a practice trial (an acclimation trial) before the official balance session, and to examine the within-session reliability of the Sway Balance Mobile Application (SBMA).Design: Retrospective observational study.Setting: Middle schools, high schools, and colleges across the United States.Participants: More than 17 000 student-athletes were included in the Sway Medical database with 7968 individuals meeting this study's inclusion criteria.Independent Variables: The Sway Medical database included the following subject characteristics for each student-athlete: age, sex, weight, and height.Main Outcome Measures: Balance assessment score generated by the SBMA.Results: Variable administration practices with significant differences between baseline session averages across methods were found. Individuals who performed an acclimation trial had a significantly higher baseline session average than those who did not. Within-session reliability estimates were in the low to adequate range (r = 0.53-0.78), with higher estimates found for 2 consecutive baseline tests (r = 0.75-0.78).Conclusions: For maximum clinical utility, a standardized protocol for postural control baseline acquisition is necessary. Acclimation trial should be administered before a baseline session to minimize variability, especially with only 1 to 2 baseline tests. The highest reliability was observed across 2 consecutive baseline tests within the same baseline session. We suggest obtaining baseline balance measurements with an acclimation trial followed by a baseline session with 2 baseline tests. Prospective studies are required for validation.

  • Normative Data for the Sway Balance System
    • Authors: Brett; Benjamin L.; Zuckerman, Scott L.; Terry, Douglas P.; Solomon, Gary S.; Iverson, Grant L.
      Abstract: imageObjective: Static balance, postural stability, and reaction time are commonly impaired after a sport-related concussion. The Sway Balance System assesses postural sway (ie, stability) and simple reaction time using the triaxial accelerometer built into iOS mobile devices. The purpose of this study was to provide normative data for children and adolescents and to examine for age and sex differences on the Sway Balance System.Design: Cross-sectional study.Setting: Middle and high schools across the United States.Participants: Participants were 3763 youth aged 9 to 21 years who completed the Sway Balance System Sports protocol in accordance with the company's recommended methods (ie, 1 acclimation trial and 2-3 baseline tests).Independent Variables: Age and sex.Main Outcome Measures: Sway Balance score (0-100) and Sway Reaction Time score (0-100).Statistical Analysis: A multivariate analysis of variance examined the effects of age and sex on balance and reaction time scores.Results: Sway Balance and Reaction Time scores significantly differed by age [F(10, 7494) = 39.68, P < 0.001, V = 0.10, = 0.05] and sex [F(4, 7494) = 55.29, P < 0.001, V = 0.06, = 0.03]. Post hoc analyses revealed that older groups generally had better scores than younger groups on all balance comparisons (ps < 0.001) and many reaction time comparisons. Girls performed better than boys on balance [F(2, 3747) = 53.79, P < 0.001, = 0.03] and boys had faster reaction times [F(2, 3747) = 37.11, P < 0.001, = 0.02].Conclusions: Age and sex are important factors to consider when assessing Balance and Reaction Time scores using the Sway Balance System's Sports protocol in youth. We provide age- and sex-based normative values for the Sway Balance System, which will likely be helpful when using this technology to assess and manage concussions.

  • Effectiveness of Field-Based Resistance Training Protocols on Hip Muscle
           Strength Among Young Elite Football Players
    • Authors: Kohavi; Bar; Beato, Marco; Laver, Lior; Freitas, Tomas T.; Chung, Linda H.; Dello Iacono, Antonio
      Abstract: imageObjective: The objective of this study was to examine the effects of an 8-week progressive resistance training program on hip joint muscles' strength measures, using the Copenhagen adduction (CA) and the sliding hip (SH) exercises.Design: Prospective randomized controlled trial.Setting: Sport training and medical centers.Participants: Forty-two young male football athletes (age 17.5 ± 1.1 years; height 178.3 ± 3.2 cm; body mass 66.1 ± 8.6 kg) allocated to a CA, SH, and matched control (C) group.Interventions: Two weekly sessions of CA and SH.Main Outcome Measures: Maximal eccentric strength test for the hip adductor (EHAD) and maximal eccentric strength test for the hip abductor (EHAB) muscles, and the relative EHAD/EHAB ratio assessed through a break test in the side-lying position.Results: No significant differences between groups were found at baseline for any of the assessed variables (all P> 0.053). The CA group had a significant strength increase in the right and left leg (d = 2.11, d = 1.9, respectively). The SH group also had a significant strength increase in the right and left leg (d = 1.68 and d = 1.67, respectively). The CA group presented EHAD/EHAB improvements in the right and left leg (d = 0.84 and d = 1.14, respectively). The SH group also presented EHAD/EHAB improvements in the right and left leg (d = 1.34 and d = 1.44, respectively).Conclusions: Both exercises' protocols were effective in inducing significant increases on EHAD, EHAB, and EHAD/EHAB ratio when compared with the control group. Practitioners should be aware of the training effectiveness of both protocols.

  • Evaluation of Muscle Injuries in Professional Football Players: Does Coach
           Replacement Affect the Injury Rate'
    • Authors: Dönmez; Gürhan; Kudas, Savas; Yörübulut, Mehmet; Yildirim, Murat; Babayeva, Naila; Torgutalp, Serife Seyma
      Abstract: imageObjectives: To assess the incidence and characteristics of muscle injuries in professional football players and to assess if coach dismissal may be related with muscle injuries within 1-month period from the dismissal.Design: Prospective cohort study during 3 consecutive seasons.Setting: Turkish Super League football teams.Participants: One hundred eighteen male football players.Main Outcome Measures: Data on time-loss muscle injuries confirmed using magnetic resonance imaging were recorded, including type, body part, duration, and lay-off time, and training session and match exposure times. The muscle injury rate was evaluated at 2 weeks and 30 days after coach dismissal.Results: In total, 124 muscle injuries were recorded, with injury incidences of 2.3 muscle injuries per 1000 hours of exposure overall, 1.2 in training sessions, and 13.6 in matches. Injury time loss ranged from 3 to 67 days (median, 13 days). Eighteen percent of the injuries (n = 23) were recurrent; no association was found between recurrence rate and the player's age or position (P = 0.15, P = 0.27, respectively). Recurrent injuries caused more severe injuries (26.1%, P = 0.02) and longer median lay-off time (P = 0.01). During the study, teams A and B replaced 7 and 3 coaches, respectively. The injury incidence increased to 5.3 per 1000 hours of exposure in the 2 weeks after the coach dismissal, and decreased to 4.5 within 1 month of coach dismissal.Conclusion: Given the link between coach dismissal and increased rates of muscle strain injuries, increased attentiveness to preventing muscle injuries during coaching transitions and to the impact of new training regimens is required by trainers and medical teams.

  • Personality and Risk Taking in Sports: A Focus on Unintentional and
           Intentional Head Impacts in Amateur Soccer Players
    • Authors: Levitch; Cara F.; Ifrah, Chloe; Kim, Mimi; Stewart, Walter F.; Lipton, Richard B.; Zimmerman, Molly E.; Lipton, Michael L.
      Abstract: imageObjective: In soccer, unintentional and intentional (heading) head impacts are associated with concussive symptoms and cognitive dysfunction. We examined whether personality traits were associated with these behaviors in soccer players.Design: Cross-sectional study.Setting and Participants: Participants completed study visits at the Albert Einstein College of Medicine. A total of 307 adult amateur soccer players, recruited from New York City and the surrounding area, completed 737 HeadCount-2w questionnaires.Predictor Variables: Personality traits (intellect/imagination, conscientiousness, extraversion, agreeableness, and neuroticism) were assessed with the Mini-International Personality Item Pool questionnaire at the baseline study visit.Main Outcome Measures: Participants completed an online questionnaire (HeadCount-2w) to ascertain frequency of intentional head impacts and occurrence of unintentional head impacts every 3 to 6 months. Generalized estimating equations repeated-measures regressions determined whether personality predicted unintentional and intentional impacts.Results: Personality traits were not associated with unintentional head impact(s) or frequency of intentional head impacts.Conclusions: These findings have important clinical implications, suggesting that personality is not driving the association between high levels of unintentional and intentional head impacts and worse neuropsychological functioning and concussive symptoms.

  • Jumper's Knee: A Prospective Evaluation of Risk Factors in Volleyball
           Players Using a Novel Measure of Injury
    • Authors: MacDonald; Kerry; Palacios-Derflingher, Luz; Kenny, Sarah; Emery, Carolyn; Meeuwisse, Willem H.
      Abstract: imageObjectives: To examine potential intrinsic risk factors that may contribute to the onset of jumper's knee in elite level–male volleyball players.Design: Prospective Cohort Study.Setting: Varsity and National team volleyball gymnasiums.Participants: Sixty elite adult male volleyball players from Canada.Assessment of Risk Factors: Players completed a series of risk factor assessments at the commencement of their seasons, including vertical jump (cm), ankle dorsiflexion range (degrees), dynamic balance (normalized distance reached; cm), dynamic knee alignment (degrees), and landing mechanics (degrees).Main Outcome Measure: Self-reported knee problems, captured via short message service.Results: Knee problem prevalence was 75% [95% confidence intervals (CIs): 62.2-84.6] and the incidence rate for substantial injuries over the study period was 30 injuries/100 players/season (95% CI: 19.5-43.1). No risk factor was found to significantly predict the future occurrence of developing jumper's knee. The odds ratios were close to unity (range: 0.94–1.07) with narrow confidence intervals and P> 0.05.Conclusions: A more sensitive capture of overuse knee problems did not result in the identification of distinct risk factors for the development of jumper's knee. These findings highlight a lack of available methodology to accurately assess risk factors for overuse injuries.

  • Quality-of-Life in Achilles Tendinopathy: An Exploratory Study
    • Authors: Ceravolo; Michael L.; Gaida, James E.; Keegan, Richard J.
      Abstract: imageObjective: This research aimed to explore the quality-of-life and experiences of people with Achilles tendinopathy.Design: This mixed-methods research used the 8-dimension Assessment of Quality-of-Life (AQoL-8D), focus groups and grounded theory analysis. AQoL-8D scores were compared with population normative scores. In focus groups, participants discussed their experiences with Achilles tendinopathy.Setting: An online survey was completed, followed by focus groups and interviews held at the University of Canberra.Participants: Adults with Achilles tendon pain were eligible to participate in the online survey, which was distributed through email and social media.Results: Complete survey responses were obtained from 92 individuals, and 11 individuals participated in focus groups and interviews. AQoL-8D scores were significantly lower in those with Achilles tendinopathy (79 ± 11 vs 81 ± 13). AQoL-8Ds of mental health, pain, senses, and the physical “super dimension” were also significantly lower. The difference exceeded the AQoL-8D minimum clinically important difference of 6% only for the pain dimension. Themes identified included adapting lifestyles, living with the condition, changes in mental and social well-being, conflict with identity, frustration, and individual experiences.Conclusions: Achilles tendinopathy is associated with a lower quality-of-life score, but on average, the difference does not exceed the minimum clinically important difference. In focus groups, some individuals described profound impacts on their life. This discrepancy likely reflects the variability of the impact across individuals. For some people, the effect is minimal, yet for those who tie their identity and social activities to fitness and physical activity, the effect can be profound.

  • The Impact of Sleep Duration on Performance Among Competitive Athletes: A
           Systematic Literature Review
    • Authors: Kirschen; Gregory W.; Jones, Jason J.; Hale, Lauren
      Abstract: image : The athletic advantage of sleep, although commonly touted by coaches, trainers, and sports physicians, is still unclear and likely varies by sport, athletic performance metric, and length of sufficient or insufficient sleep. Although recent literature reviews have highlighted circadian and nutritional factors that influence different aspects of athletic performance, a systematic summary of the effects of sleep duration and sleep quality on performance among competitive athletes is lacking. Here we systematically review the relationship between sleep duration and sleep quality and objective athletic performance among competitive athletes across 19 studies representing 12 sports. Taken holistically, we find that the sports requiring speed, tactical strategy, and technical skill are most sensitive to sleep duration manipulations. Furthermore, longer-term sleep manipulations are more likely than acute sleep manipulations (whether deprivation or extension) to affect athletic performance. Thus, the importance of sleep for competitive athletes to achieve high performance is dependent on the demands of the sport as well as the length of sleep interventions. In light of the limited number of studies investigating sleep quality and performance, the potential relevance of subjective sleep quality remains an interesting question for future work.

    • Authors: Haider; Mohammad N.; Leddy, John J.; Du, William; J. Macfarlane, Alexander; Viera, Kaitlin B.; Willer, Barry S.
      Abstract: image : This article presents a brief, focused physical examination [PE, the Buffalo Concussion Physical Examination (BCPE)] for sport-related concussion (SRC) to be considered for use in the outpatient setting by sports medicine physicians, pediatricians, and primary-care physicians. This companion paper describes how to perform the PE, which was derived in a separate study presented in this journal. It is envisioned for use at the initial and follow-up outpatient visits both for acute concussions and in patients with prolonged symptoms. A pertinent PE, combined with other assessments, can help identify specific treatment targets in those with persistent symptoms after SRC. The BCPE includes orthostatic vital signs and examinations of the cranial nerves, oculomotor/ophthalmologic, cervical, and vestibular systems. Supplementary tests, including testing for exercise tolerance and neurocognitive function, may be performed if indicated. It is recommended that a PE be performed at the initial visit and every 1 to 2 weeks after SRC. On return of symptoms, cognition, and the PE to baseline, as well as normalization of any supplementary tests, patients can begin a return to play program.

  • Can Ultrasound Identify Paradoxical Vocal Fold Movement' A Pilot Study
    • Authors: Finnoff; Jonathan T.; Orbelo, Diana M.; Ekbom, Dale C.
      Abstract: imageObjective: Vocal cord dysfunction (VCD) is characterized by paradoxical vocal fold movement (PVFM) during inspiration. The aim of this study was to determine whether ultrasound could accurately differentiate between normal and PVFM during respirations in a resting state.Design: Prospective, single-subject design.Setting: Academic medical center.Patients: A speech-language pathologist who was able to volitionally alternate between normal and PVFM when breathing at rest was recruited to participate in the study.Interventions: The subject was instructed to randomly alternate between normal and PVFM 20 times (10 times each). A single investigator imaged the vocal folds using ultrasound and reported when the subject alternated between the 2 respiratory states.Main Outcome Measures: The subject recorded when they changed between the 2 respiratory states, whether the investigator identified with the change occurred, and if the correct respiratory state was identified.Results: The investigator recognized when the subject changed respiratory states and correctly identified the new respiratory state 100% of the time.Conclusions: The findings of the current study were promising and suggest that ultrasound may have utility in the diagnosis of VCD. However, because of the preliminary nature of these results, further research is required before recommending its clinical implementation.

  • A Simplified Prediction Model for Lower Extremity Long Bone Stress
           Injuries in Male Endurance Running Athletes
    • Authors: Carbuhn; Aaron F.; Sanchez, Zack; Fry, Andrew C.; Reynolds, Matthew R.; Magee, Lawrence M.
      Abstract: imageObjective: Develop a prediction model for lower extremity long bone injuries (LBIs) in male endurance running athletes using dual-energy x-ray absorptiometry (DEXA).Design: Retrospective.Setting: Sports medicine department in a university athletic setting.Participants: National Collegiate Athletic Association (NCAA) Division 1 white male endurance athletes (n = 27).Independent Variables: Backward stepwise elimination was used to achieve a model that predicts LBI, by removing noncontributory variables (P> 0.10), using binary logistic regression. Independent prediction variables analyzed for model were as follows: (1) height (cm), body mass index (BMI) (kg/m−2), and total mass (kg); and (2) regional and total lean mass, fat mass, and bone density assessed using DEXA.Main Outcome Measures: Dichotomous dependent variable was LBI.Results: Final constructed model predicted 96.3% of athletes with and without LBI. Prediction model were as follows: predict lower extremity long bone stress injury = 23.465 − 0.896 BMI + 1.043 (total upper-body mass) TUB − 34.536 leg bone mineral density (BMD). Predict lower extremity long bone stress injury is the LBI prediction, and TUB (kg) is total fat, muscle, and bone weight in trunk and arms.Conclusions: These preliminary data suggest that Division 1 white male endurance running athletes are at risk of LBI with higher relative TUB and lower BMI in combination with a lower leg BMD.

  • Return to Competition After Surgery for Herniated Lumbar Disc in
           Professional Football Players
    • Authors: Tencone; Fabrizio; Minetto, Marco Alessandro; Tomaello, Luca; Giannini, Alessandro; Roi, Giulio Sergio
      Abstract: imageObjective: To investigate the prevalence and outcomes of surgery for lumbar disc herniation in professional football players.Design: Retrospective case series.Setting: Sports rehabilitation center.Participants: A period of 10 seasons of the Italian Football First League (Serie A) was retrospectively investigated. Thirty-three teams (for a total of 1960 players) took turns in the 10 seasons, and 42 team doctors were requested to provide information about the number of players who underwent surgery for lumbar disc herniation.Intervention: Survey distributed to team doctors.Main Outcome Measures: Prevalence and match incidence of the lumbar discectomy, proportion of players returning to competition after surgery, recovery time and preintervention and postintervention number of appearances in official matches were analyzed.Results: Eleven players underwent the surgical intervention during the considered period. The prevalence of the surgical treatment was 0.6%, whereas the match incidence was 0.09 cases/1000 match hours. All players returned to competitions 6.0 (3.5-7.7) months after surgery, with no significant difference between different roles. The number of appearances in official matches was comparable during the seasons before and after surgery.Conclusions: The lumbar discectomy must be considered a rare surgical procedure performed in professional football players. All players returned to competitions after surgery. The postintervention number of appearances in official matches was comparable with the preintervention one.

  • Concussion in Adolescents Impairs Heart Rate Response to Brief Handgrip
    • Authors: Woehrle; Emilie; Harriss, Alexandra B.; Abbott, Kolten C.; Moir, Marcy Erin; Balestrini, Christopher S.; Fischer, Lisa K.; Fraser, Douglas D.; Shoemaker, Joel Kevin
      Abstract: imageObjective: Test the hypotheses that (1) concussion in adolescents impairs autonomic neural control of heart rate (HR), and (2) HR reactivity improves with symptom resolution.Design: Observational, case–control.Participants: Nineteen concussed adolescents (8 female adolescents; age 15 ± 2 years) and 16 healthy controls (6 female adolescents, age 15 ± 2 years).Intervention: All participants performed an isometric handgrip (IHG) at 30% maximum voluntary contraction lasting 30 seconds. Heart rate (electrocardiogram) and hemodynamic responses (photoplethysmographic Finometer) were recorded from 30 seconds of baseline and the last 10 seconds of handgrip.Main Outcome Measures: The HR response (ΔHR) at the onset of moderate-intensity IHG using a mixed 1-way analysis of variance.Results: A group × time interaction (P < 0.005) indicated that handgrip evoked a greater ΔHR among control participants (13 ± 10 beats/min) compared with concussed (6.4 ± 6.3 beats/min; group P = 0.63; time P < 0.001; d = 0.77).Conclusion: These preliminary results suggest that a concussion impairs the ability to elevate HR at the exercise onset and, given the nature of the task, this could be interpreted to reflect reduced ability to withdraw cardiovagal control. Therefore, the data support the hypothesis of neural cardiac dysregulation in adolescents diagnosed with concussion.Clinical Relevance: The IHG test could aid concussion diagnosis and support return-to-play decisions.

  • Is Self-Reported Knee Stability Associated With Symptoms, Function, and
           Quality of Life in People With Knee Osteoarthritis After Anterior Cruciate
           Ligament Reconstruction'
    • Authors: Hart; Harvi F.; Collins, Natalie J.; Ackland, David C.; Crossley, Kay M.
      Abstract: imageObjective: This study aimed to investigate the association of self-reported knee stability with symptoms, function, and quality of life in individuals with knee osteoarthritis after anterior cruciate ligament reconstruction (ACLR).Setting: Cross-sectional.Participants: Twenty-eight individuals with knee osteoarthritis, 5 to 12 years after ACLR.Main Outcome Measures: Self-reported knee stability was assessed using visual analogue scales (VAS) during hop for distance (HD), side-to-side hop (SSH), and one-leg rise (OLR). Symptoms [Knee Injury and Osteoarthritis Outcome Score (KOOS) pain, Anterior Knee Pain Scale (AKPS), and International Knee Documentation Committee form], self-reported function (KOOS-sport/rec), performance-based function (hopping and OLR), and quality of life (KOOS-QOL) were assessed. K-means clustering categorized individuals into low (n = 8) and high self-reported knee stability (n = 20) groups based on participants' VAS scores during functional tasks.Results: The low self-reported knee stability group had worse knee symptoms than the high self-reported knee stability group [KOOS-pain: mean difference −17 (95% confidence interval, −28 to −5); AKPS: −10 (−20 to −1)], and worse self-reported function [KOOS-sport/rec: −33 (−48 to −18)] and performance-based function [HD: −28 (−53 to −3); SSH: −10 (−20 to −1), OLR: −18 (−32 to −50)].Conclusion: Low self-reported stability is associated with worse symptoms, and worse self-reported and performance-based function. Further research is required to determine the causation relation of self-reported knee stability to knee symptoms and function in individuals with knee osteoarthritis after ACLR.

  • King-Devick Test Time Varies by Testing Modality
    • Authors: Clugston; James R.; Chrisman, Sara P. D.; Houck, Zachary M.; Asken, Breton M.; Boone, Jonathan K.; Buckley, Thomas A.; Hoffman, Nicole L.; Schmidt, Julianne D.; Kontos, Anthony P.; Jaffee, Michael S.; Harmon, Kimberly G.; Broglio, Steven P.; McCrea, Michael A.; McAllister, Thomas W.; Ortega, Justus D.
      Abstract: imageObjective: To explore differences in baseline King-Devick Test (KD) completion time between 2 testing modalities: (1) spiral-bound paper cards (cards) and (2) iPad application (iPad).Design: Cross-sectional cohort analysis.Setting: National Collegiate Athlete Association (NCAA) institutions.Participants: Student athletes from 13 women's and 11 men's collegiate sports who completed KD baseline testing as part of their first year in the Concussion Assessment, Research and Education (CARE) Consortium from 2014 to 2016 (n = 2003, 52.2% male).Independent Variables: King-Devick Test modalities; cards or iPad.Main Outcome Measure: Baseline KD completion time (seconds).Results: Mean baseline KD completion time of the iPad modality group [42.8 seconds, 95% confidence interval (CI), 42.1-43.3] was 2.8 seconds (95% CI, 2.1-3.4) greater than the cards group (40.0 seconds, 95% CI, 39.7-40.3) (t(1, 1010.7) = −8.0, P < 0.001, Cohen's d = 0.41).Conclusions: Baseline KD performance is slower when tested on an iPad than when tested on spiral-bound paper cards. The 2 KD modalities should not be used interchangeably in concussion assessments because differences in the modalities can lead to time differences similar in magnitude to those used to indicate concussion. From a research perspective, modality may influence interpretation and/or synthesis of findings across studies.

  • Identifiable Factors Associated With Acceptance Into Sports Medicine
           Fellowship Programs: A Brief Report
    • Authors: Zaremski; Jason L.; Rao, Ashwin; Myers, Rebecca; Mautner, Ken; Berkoff, David; Ross, David; Logan, Kelsey; Horodyski, MaryBeth; Asif, Irfan M.
      Abstract: imageObjective: To identify factors associated with entry into primary care sports medicine (PCSM) fellowship programs.Design: Primary care sports medicine fellowship directors (FDs) and fellowship faculty were surveyed regarding preferences for accepting applicants into their programs.Setting: Survey study.Participants: Primary care sports medicine FDs and fellowship faculty.Assessment of Risk Factors: Questions were designed to delineate factors [clinical experience, letters of recommendation (LOR), scholarship, service commitment, interview performance, etc] perceived to be associated with entry into PCSM fellowship (1-10 scale; 10 = highest value). Weighted mean ± SD were calculated for each question.Main Outcome Measures: Determination of most valued factors for entry into PCSM fellowship.Results: Responses were provided by 242/2332 (10.4%) of the American Medical Society for Sports Medicine members, including 77 of 175 (44%) FDs. The top 3 factors for entry into PCSM fellowships for all respondents were as follows: interview performance (9.17 ± 1.13), LOR from SM fellowship faculty (8.20 ± 1.67), and high school game/event coverage (7.83 ± 1.70). Musculoskeletal ultrasound experience (4.50 ± 2.23) and residency training in pediatrics (4.58 ± 2.54), internal medicine (4.48 ± 2.44), emergency medicine (4.44 ± 2.59), and physical medicine and rehabilitation (4.40 ± 2.83) received the lowest scores.Conclusions: Applicants seeking entry into SM fellowships should prioritize performance during interviews, LOR from SM fellowship faculty, and team game/event coverage experiences.

  • Concussion Symptoms Predictive of Adolescent Sport-Related Concussion
    • Authors: Harriss; Alexandra B.; Abbott, Kolten C.; Humphreys, David; Daley, Mark; Moir, Marci Erin; Woehrle, Emilie; Balestrini, Christopher S.; Fischer, Lisa K.; Fraser, Douglas D.; Shoemaker, Joel Kevin
      Abstract: imageObjective: To assess the predictive capability of the postconcussion symptom scale (PCSS) of the sport concussion assessment tool (SCAT) III to differentiate concussed and nonconcussed adolescents.Design: Retrospective.Setting: Tertiary.Participants: Sixty-nine concussed (15.2 ± 1.6 years old) and 55 control (14.4 ± 1.7 years old) adolescents.Independent Variables: Postconcussion symptom scale.Main Outcome Measure: Two-proportion z-test determined differences in symptom endorsement between groups. To assess the predictive power of the PCSS, we trained an ensemble classifier composed of a forest of 1000 decision trees to classify subjects as concussed, or not concussed, based on PCSS responses. The initial classifier was trained on all 22-concussion symptoms addressed in the PCSS, whereas the second classifier removed concussion symptoms that were not statistically significant between groups.Results: Concussion symptoms common between groups were trouble falling asleep, more emotional, irritability, sadness, and anxious. After removal, analysis of the second classifier indicated that the 5 leading feature rankings of symptoms were headache, head pressure, light sensitivity, noise sensitivity, and “don't feel right,” which accounted for 52% of the variance between groups.Conclusions: Collectively, self-reported symptoms through the PCSS can differentiate concussed and nonconcussed adolescents. However, predictability for adolescent patients may be improved by removing emotional and sleep domain symptoms.

  • Sport Concussion Assessment Tool: Fifth Edition Normative Reference Values
           for Professional Rugby Union Players
    • Authors: Fuller; Gordon W.; Raftery, Martin
      Abstract: imageObjective: To describe distributions and establish normative ranges for new or changed subcomponents of the Sports Concussion Assessment Tool (SCAT)-5.Design: Cross-sectional study.Setting and Participants: Professional Rugby Union players performing 2017 preseason baseline SCAT-5 testing.Independent Variables: Subcomponent tests newly introduced or changed in the SCAT-5.Main Measurements: The 10-word immediate and delayed recall tests and the rapid neurological screen.Results: Thousand two hundred three players were included in complete case analyses. The 10-word immediate recall test [median score 15, interquartile range (IQR) 15-22, range 3-30] showed an asymmetrical, bimodal distribution. The delayed recall test (median score 7, IQR 5-9, range 0-10) demonstrated a left skewed distribution. The diplopia and reading/following instruction tests of the neurological screen were performed normally by virtually all participants (98.5% and 99.6%, respectively). Normative classification ranges for each SCAT-5 subcomponents of interest were determined.Conclusions: The increased spread of scores, with improved midrange centering, suggests that the increase to 10-word list lengths should improve the performance of immediate and delayed recall tests. Normative ranges will provide a distribution against which postinjury SCAT-5 scores can be compared and interpreted.

  • The Economic Burden of Pediatric Postconcussive Syndrome
    • Authors: Corwin; Daniel J.; Master, Christina L.; Grady, Matthew F.; Zonfrillo, Mark R.
      Abstract: imageObjective: To estimate the direct costs of pediatric postconcussive syndrome (PCS).Design: Retrospective cohort study.Setting: Subspecialty sports medicine clinics of a large pediatric tertiary care network in the United States.Patients: One hundred fifty-four patients aged 5 to 18 years with PCS, evaluated between 2010 and 2011.Assessment of Independent Variables: Direct costs included visits to sports medicine clinic, visio-vestibular therapy, homebound education, subspecialist referral, and prescription-only medications (amantadine and amitriptyline), all measured beginning at 28 days after injury.Main Outcome Measures: Postconcussive syndrome was defined as persistence beyond 28 days from injury.Results: The cost incurred by each PCS patient for sports medicine visits was $1575, for visio-vestibular therapy was $985, for homebound tutoring was $55, for prescription medications was $22, and for subspecialist referral was $120, totaling $3557 per patient, with a 95% confidence interval range of $2886 to $4257.Conclusions: Given the high economic costs of PCS determined in this study, therapies that mitigate this syndrome may have the potential to be cost-effective and even cost saving.

  • Donor-Specific Human Leukocyte Antigen Antibody Formation After Distal
           Tibia Allograft and Subsequent Graft Resorption
    • Authors: Liwski; Christopher R.; Dillman, Daryl; Liwski, Robert S.; Wong, Ivan H.
      Abstract: image : The association between donor-specific human leukocyte antigen (HLA) antibody formation and small bone allograft resorption has not been studied. We present the case of a patient treated for glenoid bone loss using a distal tibial allograft with Bankart repair who formed donor-specific HLA antibodies against the allograft and had subsequent graft resorption. X-ray and computed tomography (CT) scans were performed before and after surgery at standard checkpoints. Patient blood and serum samples were collected before and after surgery for HLA typing and HLA antibody testing. Human leukocyte antigen antibodies against the donor-specific HLA-A2 antigens were identified 6 weeks after surgery and were still detected at 5 months after surgery. At 6 months after surgery, a CT arthrogram revealed significant graft resorption. This case shows a temporal correlation between HLA antibody formation and clinical findings, potentially suggesting an association between HLA antibody formation and graft resorption. Further study is required to confirm this.

  • Partial Pericardial Agenesis Mimicking Arrhythmogenic Right Ventricular
    • Authors: Castelletti; Silvia; Crotti, Lia; Dagradi, Federica; Rella, Valeria; Salerno, Sabrina; Parati, Gianfranco; Cecchi, Franco
      Abstract: image : Absence of the pericardium is a rare congenital disease in which the fibroserum membrane covering the heart is partially or totally absent. It is characterized by few echocardiography (ECG) and imaging features that can mislead the diagnosis to an inherited cardiac disease, such as arrhythmogenic right ventricular cardiomyopathy. Although it has often a benign course, this congenital defect should be identified as in some cases herniation and strangulation can be life-threatening and cause sudden cardiac death. Red flags on ECG (sinus bradycardia, variable T-wave inversion), chest x-ray (Snoopy sign, absence of tracheal deviation, and esophagus impression), and transthoracic echocardiogram (unusual windows, teardrop left ventricle, and elongated atria) should rise the suspicion of pericardium absence. The correct diagnosis, confirmed by cardiac magnetic resonance, is mandatory as the consequences on the sport activity certification, the management, and the treatment are extremely different.

  • Delayed-Union of Acetabular Stress Fracture in Female Gymnast: Use of
           Teriparatide to Augment Healing
    • Authors: Gende; Alecia; Thomsen, Timothy W.; Marcussen, Britt; Hettrich, Carolyn
      Abstract: image : Pelvic stress fractures are rare and present unique challenges for medical personnel. Delayed healing can lead to increased physical, psychological, and social stress for athletes. Recent literature suggests effective use of a synthetic derivative of parathyroid hormone, teriparatide, to augment healing of delayed-union stress fractures. We present a case of a female National Collegiate Athletic Association Division I gymnast successfully returned to play after a 12-week course of teriparatide injections for an ischioacetabular stress fracture.

  • Exertional Heatstroke in a Marathon Runner Complicated by Concurrent Use
           of an Antipsychotic Medication Affecting Thermoregulation
    • Authors: Gessel; Trevor; Lin, Cindy Y.
      Abstract: image : We report the case of a half-marathon runner who presented with exertional heatstroke (EHS), whose management was confounded by concurrent treatment of his bipolar disorder with olanzapine. Antipsychotics can have a profound effect on thermoregulation and can cause athletes to present with features of neuroleptic malignant syndrome in the setting of EHS. It is vital for medical providers to consider the thermoregulatory effects of all medications, including antipsychotics, when providing care during sporting events.

  • A Case of Intermittent Exercise–Induced Foot Drop in a Recreational
    • Authors: Sheridan; Craig J.; Bowditch, Mark
      Abstract: image : Foot drop is a reduction in ankle dorsiflexion during the swing phase of gait. We report a case of a 51-year-old recreational runner and cyclist who presented with intermittent left foot drop initially triggered by running distances in excess of 10 km. The patient was investigated with magnetic resonance imaging (MRI) of the spine and leg, nerve conduction studies, electromyography, and compartment pressure testing, which were all normal. Surgical release of fascia, which was restricting the common peroneal (fibular) nerve, failed to resolve her symptoms. Subsequent brain MRI revealed demyelination. This case describes the unusual case of a recreational runner presenting with exercise-induced foot drop secondary to multiple sclerosis (MS). Motor fatigability is a common feature of MS, and this case highlights the need to remain cognizant of central and peripheral causes of exertional lower limb pathology, particularly in the absence of pain.

  • Severe Acquired Hypokalemic Paralysis in a Bodybuilder After
           Self-Medication With Triamterene/Hydrochlorothiazide
    • Authors: Pfisterer; Nikolaus; Stöllberger, Claudia; Finsterer, Josef
      Abstract: imageBackground: Severe hypokalemia with severe neurological impairment and electrocardiogram (ECG) abnormalities due to the misuse of triamterene/hydrochlorothiazide (HCTZ) in a bodybuilder has not yet been reported.Case Report: A 22-year-old bodybuilder developed acute generalized muscle cramps, sensory disturbance of the distal lower and upper limbs, quadriparesis, and urinary retention. These abnormalities were attributed to severe hypokalemia of 1.8 mmol/L (normal range 3.4-4.5 mmol/L) due to misuse of triamterene/HCTZ together with fluid restriction. He was cardiologically asymptomatic, but ECG revealed a corrected QT (QTc) interval of 625 ms. On intravenous application of fluids along with intravenous and oral substitution of potassium, his condition rapidly improved, such that the sensory disturbances, quadriparesis, and bladder dysfunction completely resolved within 2 days after admission.Conclusions: Self-medication with diuretics along with fluid restriction may result in severe hypokalemia, paralysis, and ECG abnormalities. Those responsible for the management of bodybuilding studios and competitions must be aware of the potential severe health threats caused by self-medication with diuretics and anabolic steroids. Although triamterene is potassium-sparing, it may enhance the potassium-lowering effect of HCTZ.

  • Arcuate Pubic Ligament Injury—An Unknown Cause of Athletic Pubalgia
    • Authors: Mathieu; Thomas; Gielen, Jan; Vyncke, Guido; Stassijns, Gaëtane
      Abstract: image : A case report is presented that gives new insight into a very rare cause of athletic pubalgia. Up till now, no case has been published in literature about the relevance of an arcuate pubic ligament (APL) injury in athletic pubalgia. The APL or inferior pubic ligament is a thick triangular arch of ligamentous fibers connecting the 2 pubic bones below. The main function of the APL is to stabilize the symphysis pubis. The rupture of this ligament can lead to groin pain due to lack of stabilization of the symphysis pubis. Despite the importance of the anatomical and clinical function of the APL, very limited research is available about injuries of this ligament. This report describes a case of a traumatic left APL rupture, confirmed by magnetic resonance imaging, causing longstanding left groin pain in an amateur athlete.
