Emily Kraus, MD
- Clinical Assistant Professor
I love helping injured young athletes get back to the activities and sports they love, and I enjoy working with players, coaches and trainers to prevent sports injuries before they happen. I work with a multidisciplinary team that includes orthopedic surgeons, athletic trainers, physical therapists and more to provide my patients with seamless, connected care.
I’ve had the good fortune of finding a job that allows me to not just manage sports injuries but truly treat the entire athlete. In sports medicine, it’s essential that we think about every aspect of healing and injury prevention, including nutrition, stress, training and sports psychology. When an athlete walks into my clinic, he or she will be welcomed with a smile, treated with respect and given the most individualized care I can provide. I embrace questions and interactive visits!
I especially enjoy those moments when I see the fire return to the eyes of an athlete who’s recovering from injury. That’s when I know the athlete gets it and is committed to the treatment plan.

Dietary Supplement Use According to Sex and Triad Risk Factors in Collegiate Endurance Runners. Journal of strength and conditioning research 2020
Abstract
Barrack, MT, Fredericson, M, Dizon, F, Tenforde, AS, Kim, BY, Kraus, E, Kussman, A, Singh, S, and Nattiv, A. Dietary supplement use according to sex and Triad risk factors in collegiate endurance runners. J Strength Cond Res XX(X): 000-000, 2020-This cross-sectional study evaluated the prevalence in the use of dietary supplements among elite collegiate runners among 2 NCAA Division I cross-country teams. At the start of each season from 2015 to 2017, male and female endurance runners were recruited to complete baseline study measures; the final sample included 135 (male n = 65, female n = 70) runners. Runners completed a health survey, web-based nutrition survey, and Triad risk assessment. The prevalence of dietary supplement use and Triad risk factors, including disordered eating, low bone mass, amenorrhea (in women), low body mass index, and stress fracture history, was assessed. A total of 78.5% (n = 106) runners reported taking 1 or more supplements on 4 days per week over the past month, 48% (n = 65) reported use of 3 supplements. Products used with highest frequency included multivitamin/minerals 46.7% (n = 63), iron 46.7% (n = 63), vitamin D 34.1% (n = 46), and calcium 33.3% (n = 45). More women, compared with men, used iron (61.4 vs. 30.8%, p < 0.001) and calcium (41.4 vs. 24.6%, p = 0.04); men exhibited higher use of amino acids and beta-alanine (6.2 vs. 0%, p = 0.04). Runners with bone stress injury (BSI) history, vs. no previous BSI, reported more frequent use of 3 supplements (61.5 vs. 32.8%, p = 0.001), vitamin D (49.2 vs. 19.4%, p < 0.001), and calcium (47.7 vs. 19.4%, p = 0.001). Low bone mineral density was also associated with higher use of vitamin D and calcium. Most runners reported regular use of 1 or more supplements, with patterns of use varying based on sex, history of BSI, and bone mass.

Youth running consensus statement: minimising risk of injury and illness in youth runners. British journal of sports medicine 2020
Abstract
Despite the worldwide popularity of running as a sport for children, relatively little is known about its impact on injury and illness. Available studies have focused on adolescent athletes, but these findings may not be applicable to preadolescent and pubescent athletes. To date, there are no evidence or consensus-based guidelines identifying risk factors for injury and illness in youth runners, and current recommendations regarding suitable running distances for youth runners at different ages are opinion based. The International Committee Consensus Work Group convened to evaluate the current science, identify knowledge gaps, categorise risk factors for injury/illness and provide recommendations regarding training, nutrition and participation for youth runners.

Prevalence of Female Athlete Triad Risk Factors and Iron Supplementation Among High School Distance Runners: Results From a Triad Risk Screening Tool. Orthopaedic journal of sports medicine 2020; 8 (10): 2325967120959725
Abstract
Investigations of the female athlete triad (Triad) in high school athletes have found that 36% had low energy availability, 54% had menstrual abnormalities, and 16% had low bone mineral density (BMD). Limited data are available showing the prevalence of these risk factors in high school distance runners or regarding best practice on screening for the Triad in the adolescent population.To (1) evaluate the prevalence of Triad risk factors and iron supplementation in high school distance runners and (2) pilot a screening tool for Triad risk score.Descriptive epidemiology study.The study population included female high school athletes who participated in cross-country/track. Participants completed a survey including questions regarding dietary habits, menstrual history, and bone stress injury (BSI) history. They then underwent evaluation of 25-hydroxyvitamin D, free triiodothyronine (T3), and dual-energy x-ray absorptiometry scan to measure body fat and BMD through use of age-, sex-, and ethnicity-matched Z scores. Triad scores were calculated. Relationships were analyzed using Spearman correlation coefficient.There were 38 study participants (mean age, 16.9 years). Average body mass index was 19.8 kg/m2. Disordered eating or eating disorders were reported in 76.3% of runners; in addition, 23.7% reported delayed menarche, 45.9% had a history of amenorrhea or oligomenorrhea, 42.1% had low BMD (Z score < -1.0), and 15.8% reported prior BSI. Low free T3 was significantly associated with higher Triad risk scores (rS = -0.36; P = .028). More than 42% of athletes were supplementing iron.The prevalence of Triad risk factors in high school distance runners was high. Free T3 was inversely associated with Triad score, which may serve as an indicator of low energy availability. Nearly half of the athletes were using iron supplementation.

Impact of Adaptive Sports Participation on Quality of Life. Sports medicine and arthroscopy review 2019; 27 (2): 7382
Abstract
The health benefits of regular recreational physical activity are well known in reducing secondary health consequences of a sedentary lifestyle in the general population. However, individuals with physical disabilities participate less frequently in recreational activity compared with those without disabilities. Although evidence on the impact of recreational physical activity on quality of life in this population is in its infancy, regular recreational and sports activity participation has shown to have a positive association with improvements in quality of life, life satisfaction, community reintegration, mood, and employment in those with disabilities. Facilitators of participating in adaptive sports include a desire to improve social support, physical fitness, health, and fun. Unfortunately, those with disabilities face numerous barriers to participate in adaptive sports including accessibility, transportation, awareness, finances, and physical and cognitive impairments. Further studies are needed to investigate facilitators and barriers to participating in adaptive sports to capitalize on the physical and psychosocial benefits of regular recreational activity. The aim of this article is to review the available literature on the effects of adaptive sports participation on quality of life.

Bone stress injuries in male distance runners: higher modified Female Athlete Triad Cumulative Risk Assessment scores predict increased rates of injury. British journal of sports medicine 2018
Abstract
OBJECTIVES: Bone stress injuries (BSI) are common in runners of both sexes. The purpose of this study was to determine if a modified Female Athlete Triad Cumulative Risk Assessment tool would predict BSI in male distance runners.METHODS: 156 male runners at two collegiate programmes were studied using mixed retrospective and prospective design for a total of 7years. Point values were assigned using risk assessment categories including low energy availability, low body mass index (BMI), low bone mineral density (BMD) and prior BSI. The outcome was subsequent development of BSI. Statistical models used a mixed effects Poisson regression model with p<0.05 as threshold for significance. Two regression analyses were performed: (1) baseline risk factors as the independent variable; and (2) annual change in risk factors (longitudinal data) as the independent variable.RESULTS: 42/156 runners (27%) sustained 61 BSIs over an average 1.9 years of follow-up. In the baseline risk factor model, each 1 point increase in prior BSI score was associated with a 57% increased risk for prospective BSI (p=0.0042) and each 1 point increase in cumulative risk score was associated with a 37% increase in prospective BSI risk (p=0.0079). In the longitudinal model, each 1 point increase in cumulative risk score was associated with a 27% increase in prospective BSI risk (p=0.05). BMI (rate ratio (RR)=1.91, p=0.11) and BMD (RR=1.58, p=0.19) risk scores were not associated with BSI.CONCLUSION: A modified cumulative risk assessment tool may help identify male runners at elevated risk for BSI. Identifying risk factors may guide treatment and prevention strategies.

A Review and Proposed Rationale for the use of Ultrasonography as a Diagnostic Modality in the Identification of Bone Stress Injuries. Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine 2018
Abstract
Bone stress injuries are common in military personnel and athletes. The delayed diagnosis of a bone stress injury can lead to a more severe injury that requires a longer period of treatment. The early detection of bone stress injuries is a central part of management. Currently, the reference standard for detecting bone stress injuries is magnetic resonance imaging. However, the expanding use of point-of-care ultrasonography (US) may enable the early detection of bone stress injuries in the clinical setting. In this article, we review the US detection of bone stress injuries, as well as discuss the rationale for the use of US in the diagnosis of these injuries.

Integrating Musculoskeletal Education and Patient Care at MedicalStudent-Run Free Clinics. PM & R : the journal of injury, function, and rehabilitation 2017
Abstract
Student-run free clinics (SRFCs) have emerged as an important educational component of United States (US) medical schools. Despite the prevalence of musculoskeletal (MSK) problems presenting to SRFCs, students and clinics are often unprepared to diagnose and to treat common MSK complaints.We sought to determine the scope of diagnosis and treatment at a medical student-run free clinic specializing in musculoskeletal care using physical medicine and rehabilitation (PM&R) residents. Secondary goals included reviewing student satisfaction and determining the appropriateness of the clinic in medical education.Retrospective chart review, anonymous online survey.Primary care, free student clinic affiliated with tertiary academic medical center.A total of 20 medical student volunteers, 6 PM&R residents, and 91 community patients.We established a musculoskeletal clinic as a specialty referral clinic for the 2 primary care SRFCs with institutional support from a partner medical school. We then reviewed clinical operations retrospectively using electronic medical records and student satisfaction based on an online survey.We analyzed patient demographics and chief complaints, referrals provided, and medical services rendered. We also used a 5-point Likert scale to assess student satisfaction.A monthly musculoskeletal referral clinic was established with the oversight of PM&R attendings and residents. The clinic received 91 referrals and managed 61 unique patients over a 2.5-year study period. The most common presentations to the clinic involved knee pain (n = 17, 27.9%) and back pain (n = 16, 26.2%). Pro bono relationships with community and institutional partners enabled all patients to receive medical examinations, physical therapy visits, plain film radiographs, and insurance consultations free of charge. Student satisfaction with teaching and patient care was high, with 19 of 20 students reporting their experience as "good" or "excellent."SRFCs represent an underused opportunity to enhance MSK education among medical students by treating a variety of common MSK complaints in an underserved population.To be determined.

Piriformis Syndrome With Variant Sciatic Nerve Anatomy:ACaseReport. PM & R : the journal of injury, function, and rehabilitation 2016; 8 (2): 176-179
Abstract
A 68-year-old male long distance runner presented with low back and left buttock pain, which eventually progressed to severe and debilitating pain, intermittently radiating to the posterior thigh and foot. A comprehensive workup ruled out possible spine or hip causes of his symptoms. A pelvic magnetic resonance imaging neurogram with complex oblique planes through the piriformis demonstrated variant anatomy of the left sciatic nerve consistent with the clinical diagnosis of piriformis syndrome. The patient ultimately underwent neurolysis with release of the sciatic nerve and partial resection of the piriformis muscle. After surgery the patient reported significant pain reduction and resumed running 3 months later. Piriformis syndrome is uncommon but should be considered in the differential diagnosis for buttock pain. Advanced imaging was essential to guide management.

Bone Stress Injuries in Runners. Physical medicine and rehabilitation clinics of North America 2016; 27 (1): 139-149
Abstract
Bone stress injuries (BSIs) are common running injuries and may occur at a rate of 20% annually. Both biological and biomechanical risk factors contribute to BSI. Evaluation of a runner with suspected BSI includes completing an appropriate history and physical examination. MRI grading classification for BSI has been proposed and may guide return to play. Management includes activity modification, optimizing nutrition, and addressing risk factors, including the female athlete triad. BSI prevention strategies include screening for risk factors during preparticipation evaluations, optimizing nutrition (including adequate caloric intake, calcium, and vitamin D), and promoting ball sports during childhood and adolescence.
