Current Trends in Youth Sports Injuries Jeff G. Konin, PhD, ATC, PT Associate Professor & Vice Chair Objectives of This Course 1. Identify the epidemiology of injuries sustained by children playing sports 2. Discuss practical injury prevention programs for simple implementation 3. Identify trends in the use of protective youth sports equipment 4. Discuss the impact emergency planning has on reducing catastrophic youth sports injuries Konin Copyright 2009 Epidemiology of Youth Sports Injuries: Startling Statistics! • Approximately 20 percent of children and adolescents participating in sports activities are injured each year, and one in four injuries is considered serious. • Children and adolescents who are just beginning a sport or activity are at greater risk for injury. Konin Copyright 2009 National Center for Sports Safety & Safe Kids USA National surveillance for sports injuries among US high school student-athletes, 2003 youth risk behavior survey Hootman, JAT 2006* • N = 15,214, in 2003 (athletes = 53.7%) • High risk dieting behaviors were associated with greater injury rates – fasting, dieting, vomiting • Also tobacco, alcohol, psychological distress Konin Copyright 2009 Slowly Creeping Up………….. • 1.5 million injuries a year with BMX bikes • 2.6 million injuries a year skateboarding • Over 3 million injuries per year in-line skating • 65 thousand injuries per year horseback riding • Nearly 68 thousand kids were treated last year for trampoline injuries Konin Copyright 2009 Who Manages Youth Injuries? • Parents • Coaches • Friends • • • • • Physicians Physical Therapists Athletic Trainers Physical Educators Others Konin Copyright 2009 What role does obesity play in today’s youth sport’s injuries? Konin Copyright 2009 Be careful with BMI – people can over or under react! Here are some celebrities and athletes that the government has deemed "overweight": Michael Jordan: 6'6": 216 lbs: 25 Bobby Labonte: 5'9": 170 lbs: 25 Karl Malone: 6'9": 259 lbs: 28 Yao Ming: 7'6": 310 lbs: 27 Brad Pitt: 6'0": 203 lbs: 28 Keanu Reeves: 6'1": 223 lbs: 29 Cal Ripken: 6'4": 210 lbs: 27 Nykesha Sales: 6'0": 184 lbs: 25 Will Smith: 6'2": 210 lbs: 27 Bruce Willis: 6'0": 200 lbs: 29 Konin Copyright 2009 Sports Psychology in Children’s Sports The mind of a child is highly influenced by the parent and coach! Konin Copyright 2009 Abrams, Center for Sports Parenting 2005 “70 percent of kids drop out of sports by age 13, and the main reason is pressure from parents and coaches.” Bob Bigelow, one of the authors of ``Just Let the Kids Play,'' believes the odds of winning a scholarship are even more remote than many other experts say, estimating that just 1 in 300 high school senior athletes will get a fabled “full ride.'' Konin Copyright 2009 Unrealistic expectations of parents In Northern California today: > There are about 2,000 club soccer teams > There is a decline in the number of multi-sport athletes as kids specialize in one sport to maximize their scholarship chances. Konin Copyright 2009 • The Northeastern University Center for the Study of Sport in Society found that, of black teens, 66 percent believe they will ultimately play pro ball. Konin Copyright 2009 Behavioral Response Of Injury The Injury Itself • The stressor, loss of self-control Konin Copyright 2009 Behavioral Response to Injury Emotional Responses Denial Anger Frustration Bargaining Depression Acceptance Konin Copyright 2009 Educate The Athlete… and the parent! • First – assess parental knowledge in general and current disposition • Explain facts about the injury • Realistic expectations of recovery • Importance of psychological skills as a part of the rehabilitation process • Allow athlete to educate you Konin Copyright 2009 Case Study • How would you counsel a 12 year old child and parents referred to you with OSD and wanting to return to playing basketball? • Topics might include: learning what the MD told them, their goals, their realisms, their timeline, what they googled, child’s interests, compliance, motivation, past experiences Konin Copyright 2009 Protective Equipment: Rules, benefits, considerations & knowledge Purposes of Protective Equipment 1. Dispose & absorb forces 2. Limit anatomical movement 3. Support joint structures 4. Support musculotendinous structures 5. Enhance proprioceptive feedback 6. Secure protective pads Source: JG Konin et al, in The Athlete’s Shoulder, 2nd Ed, 2009 Konin Copyright 2009 Protective Equipment Guide • Does the equipment protect the area of concern appropriately? • Can the athlete perform the skills required for his/her sport and position while wearing the device? • Will the device maintain proper anatomical alignment? • Is the device potentially hazardous or injurious to other participants? • Is the device legal by the rules and regulations of the sport?

Additionally, these younger athletes are maturing at a relatively fast rate and will likely require more frequent updates of baseline measures compared with older athletes. Source: JAT 2004 Position Statement Konin Copyright 2009 Because damage to the maturing brain of a young athlete can be catastrophic (ie, almost all reported cases of secondimpact syndrome are in young athletes), athletes under age 18 years should be managed more conservatively, using stricter RTP guidelines than those used to manage concussion in the more mature athlete. Source: JAT 2004 Position Statement Konin Copyright 2009 F/U Guidelines • Avoid meds – only acetaminophen from MD • Avoid ingesting alcohol, illicit drugs, or other substances • Instructed to rest, but complete bed rest is not recommended • Eat a well-balanced diet that is nutritious in both quality and quantity • An athlete should be awakened during the night to check on deteriorating signs and symptoms only if he or she experienced LOC, had prolonged periods of amnesia, or was still experiencing significant symptoms at bedtime Source: JAT 2004 Position Statement Konin Copyright 2009 Recovery patterns of athletes reporting posttraumatic headache following sports-related concussion Register et al, JAT 2006* • Prospective randomized experimental study • 375 concussed high school and collegiate athletes average age 16.65 +/- 1.87 • Self-reported graded symptom checklist (GSC) • Days 1,3, & 7 post injury data collection • Conclusion: young athletes reporting PTH following a concussion endorse a higher number of symptoms and demonstrate decreases in neurocognitive performance when compared to those not reporting PTH • Thus, headache is a sign of incomplete recovery Konin Copyright 2009 Concussion Gender Differences in Youth Divine et al 2007 MSSE* • Female athletes have higher severity o symptoms and longer recovery rates • This was only seen when comparing nonhelmeted athletes • Unsure of reasons why Konin Copyright 2009 Concussion Management What would you say is the most practical and affordable method of decisionmaking following a concussion for those settings without large budgets and personnel resources? Konin Copyright 2009 Younger Athletes Slower to Recover from Concussions, Studies Show posted 02/02/09 5:45 pm ROCKVILLE, Md. - Every year more than 300,000 people report getting concussions from sports. But experts say millions more likely go undiagnosed. And while we see professional athletes like Super Bowl quarterback Ben Roethlisberger bounce back, for kids and teenagers it can be a long road to recovery.

EBSM 2002 Konin Copyright 2009 High Ankle Sprain (SYNDESMOTIC) • Tib-Fib Sprain (anterior/posterior) • Mechanism of injury is fixation and rotation • Treatment is difficult due to lack of good support for this area internally & externally Konin Copyright 2009 Managing The High Ankle Sprain Be patient! Tell the athlete to be patient! Tell the parents to be patient! Tell the coach to be patient! Konin Copyright 2009 Failing to Plan = Planning to Fail • Emergency Action Planning • Build from existing templates & models • Follow nationally and regionally accepted standards of policies & procedures • Identify key steps – don’t guess – What key components should be included? – Who are the stake holders? – What expenses might exist? Konin Copyright 2009 Field Safety • Uneven playing surfaces • Surfaces with greater than normal friction, ie old hardwood courts • Slippery playing surfaces, fields with puddles • Improper illuminated lighting for night events • Irrigation systems not completely buried • Baseball dugouts without proper protection from hit balls • Fences and that surround fields with protruding parts • Goalposts and other fixed apparatus that are not properly protected with padding Konin Copyright 2009
