About
Meredith T. Ehn, DO, DPT, CAQSM, is a board-certified specialist in Physical Medicine & Rehabilitation and Sports Medicine. She specializes in the diagnosis and non-surgical treatment of complex musculoskeletal conditions and sports injuries in both athletes and non-athletes, including adaptive athletes. She utilizes musculoskeletal ultrasound to aid in diagnosis and treatment. Dr. Ehn works as a consult attending at University Hospital and maintains an outpatient practice focused on adaptive musculoskeletal and sports medicine. Her clinical work often spans the full spectrum of patient recovery. Her particular interests include the treatment of acute and chronic injuries in cyclists and skiers of all ability levels. She serves as the head team physician for US Para Snowboarding and is a sports medicine consultant for US-based women’s professional cycling teams. She has provided medical coverage at events such as the UCI Tour of Utah, Salt Lake Criterium, NCAA, and World Cup Skiing and Para Snowboarding competitions. Prior to her medical career, she spent nine years as an orthopedic and sports physical therapist, specializing in rehabilitation related to cycling and skiing injuries. Her research focuses on the epidemiology and prevention of injuries in cyclists and skiers, with current projects including injury epidemiology and prevention in youth mountain bike racing. Additionally, Dr. Ehn is an Associate Program Director of the Physical Medicine & Rehabilitation residency program.

Interscholastic youth cross-country mountain bike racing in the United States has grown significantly over the past decade, yet little is known about the risk profile in this age group. Aiming to protect participants, we implemented a prospective, longitudinal injury surveillance system for the purpose of better understanding youth mountain biking injuries and implementing safety measures. Data were collected during competition years 2018-2020, totaling 66,588 student athlete-years. Designated reporters from each team received weekly emails with exposure and incident report forms. Variables analyzed included demographic, rider-related, trail-related, and other data. Injury characteristics during the COVID-19 pandemic in 2020 were compared to the years 2018 and 2019. More student athletes participated in the 2020 season (25,261) than in prior seasons (18,575 in 2018 and 22,752 in 2019). During competition year 2020, overall injury proportion was lower (1.7% versus 3.0% in 2018 and 2.7% in 2019). Variables associated with injury, body part injured, type of injury, time-loss, and disposition following injury were similar between all years. Despite the pandemic and resultant changes to competition, student athletes continued to ride their bikes and become injured, but the proportion of injuries differed. This report details injury characteristics in youth mountain bike racing, including a comparison of before and during the pandemic.

articleOpen access1st authorCorresponding<h3>Background</h3> Youth mountain bike racing is a rapidly growing sport in the United States. An injury surveillance system (ISS) is now implemented through a collaboration between University of Utah researchers and the National Interscholastic Cycling Association (NICA), referred to as NICA-ISS, to better understand injury characteristics in this sport and pursue data-driven injury prevention strategies. <h3>Objective</h3> Describe types of and factors associated with injuries sustained by youth mountain bike racers during NICA-sanctioned mountain bike racing and training. <h3>Design</h3> NICA-ISS was developed using a web-based system. Data were collected from NICA leagues during the 2018–2020 seasons. Designated reporters on each team were asked to complete weekly incident and exposure report forms. <h3>Setting</h3> Nation-wide youth mountain biking leagues in the United States. <h3>Participants</h3> Student-athletes on NICA teams in grades 8–12 participating in the 2018–2020 seasons. <h3>Assessment of Risk Factors</h3> Variables analyzed included injury characteristics, athlete demographics, trail conditions, incline during crash, weather, crash circumstances (practice, race, passing, trail familiarity), and health factors (dehydration, sleep, illness). <h3>Main Outcome Measurements</h3> Proportions/rates of injuries overall, by type and location, and by group of athletes. <h3>Results</h3> Injuries were tracked in 66,588 student-athlete-years, resulting in 2,587 injuries in 1,677 student-athlete injury events reported. The most commonly reported injury was concussion (23.3%), followed by injury to the wrist/hand (22.7%), shoulder (16.7%), and knee (14.3%). Over a half (52.1%) of injury events occurred on downhills. Males and females reported similar injury rates (2.43% and 2.86%, respectively), but females sustained significantly more lower limb injuries (p = 0.003). A large portion (72.4%) of injured athletes were unable to complete the ride; 49.3% of crashes resulted in an emergency room visit. <h3>Conclusions</h3> Acute traumatic injuries are common in mountain bike racing, including concussions and injuries to the upper extremities. Males and females have similar injury rates but different injury types. To our knowledge, this is the largest mountain bike racing ISS in existence.

articleOpen access1st authorCorresponding<h3>Background</h3> As youth mountain bike racing is a rapidly growing sport in the United States, it is essential to monitor injuries in both student-athletes and coaches who ride with student-athletes during practices. An injury surveillance system (ISS) implemented through a collaboration between University of Utah researchers and the National Interscholastic Cycling Association (NICA), referred to as NICA-ISS, helps to better understand injury characteristics in this sport and pursue data-driven injury prevention strategies. <h3>Objective</h3> Describe the types of and factors associated with injuries sustained by coaches during NICA-sanctioned mountain bike training. <h3>Design</h3> Data were collected via NICA-ISS, developed using a web-based system, from NICA leagues during the 2018–2020 racing seasons. A designated reporter from each team reported injuries sustained by coaches along with those sustained by student-athletes. <h3>Setting</h3> Nation-wide youth mountain biking leagues in the United States. <h3>Participants</h3> NICA coaches participating in the 2018–2020 seasons. <h3>Assessment of Risk Factors</h3> Variables analyzed included injury characteristics, coach demographics, and factors associated with injuries. <h3>Main Outcome Measurements</h3> Summary measures (frequency and proportion) of injuries and associated factors. <h3>Results</h3> Injuries were tracked in 31,280 coach-years, resulting in 407 injuries in 227 reported injury events. The most commonly reported injury was to the shoulder (34.8%), followed by concussion (17.6%) and wrist/hand (17.6%). 57.3% of injuries occurred on downhills. Males and females reported similar injury rates (0.70% and 0.80%, respectively). Injury characteristics differed between sexes, with female coaches sustaining more lower limb injuries while males sustained more upper limb injuries. Whereas 56.4% of crashes resulted in an emergency room visit, 9.3% required hospital admission. Nearly half (48.3%) of injury events resulted in time-loss of 4 weeks or greater. <h3>Conclusions</h3> Acute traumatic injuries are common in mountain bike racing coaches and in student-athletes. Dissimilarly to student-athletes, coaches sustain upper extremity injuries more often than concussions. To our knowledge, this is the first ISS to track injuries in mountain bike racing coaches.
