3 Review the importance of injury prevention programs List 3 evidence-based injury prevention programs Be aware of injury prevention resources

4 Sports injuries are common! Pain & suffering Lost time from sports Time of increased depression risk Re-injury risk increases Financial implications Long term issues

5

6 Screening Equipment Facilities/Environment Education Rules Conditioning/Rehab Optimal treatment of injuries to prevent reinjury

7 PPEs: Look for at risk athletes Injury Hx Family Hx ROS PE?EKG: Debate Education Concussion Sun screen etc

8 Helmets, mouthguards, face shields, eye protection, pads Break away bases, padded goal posts Emergency equipment

9 Facility regulations Zoning laws ADA Sports Organizations Heat Illness Prevention Soccer: shorter halves & increased H20 breaks

10 Spear tackling in football Decreased the risk of catastrophic cervical spine injuries

11 ACL injury prevention Hamstring strain prevention Ankle sprain prevention

12 250,000 ACL injuries/yr in USA 1in 3000 $1.5 billion annual cost > 70% ACL injuries are NON-contact 80-90% return to previous level of play Season ending injury Recovery 6-9 mo Females at higher risk

13 Lots of programs Different amount of time (10-90 min) Duration: 6 wks-whole season Variety of exercises Best results w/ the combination of Neuromuscular training Strength Plyometrics Jumping & landing techniques

14 At least 42 programs ( ) Only 5 programs w/ published data on performance testing & injury reduction 2 (Sportsmetrics & PEP) showed significant reductions in ACL tears in HS girls soccer & basketball 1 (PEP) approached significance in college Noyes & Barber Westin, Sports Health 2012;4(1):36-46

21 Sugimoto BJSM 2012 Reviewed 12 NMT studies in female athletes NNT = 108 to prevent 1 non-contact ACL tear Relative risk reduction 73% non-contact Reduction in other knee & ankle injuries?performance improvement Limitations: High NNT, Compliance & Generalizability

22 Grimm; AJSM 2015 Meta-analysis & systematic review 9 RCTs; 11,562 athletes Knee injury or ACL prevention programs Knee injury prevention: Knee injuries reduced ACL prevention: No significant change

23 Meyer; BJSM 2017 Systematic review Neuromuscular/proprioceptive interventions to prevent knee injuries & ACL tears 24 studies; >26,000 subjects 63% female Knee injuries decreased by 27% ACL injuries decreased by 51%

24 Nordic Hamstring Exercise Program Oslo Sports Trauma Research Center Focus: Injury Prevention Eccentric strengthening

25

26 Peterson, AJSM 2011 Aim: Prevent new hamstring injuries 942 soccer players 10 wk hamstring eccentric strengthening No injuries during 10 wk program Overall combine reduction: 70% NNT New injury: 25 (95% CI: 15-72) Recurrent: 3 (95% CI: 2-6) Combined: 13 (95% CI: 9-23)

27 Braces, taping & NMT are effective for preventing recurrences Strongest literature for NMT Limited effect for 1 st time ankle sprain prevention Tape or Brace + NMT= best prevention outcome Verhagen: Optimising ankle sprain prevention: a critical review and appraisal of the literature. BJSM 2010

28 STOP Sports Tauma & Overuse Prevention AOSSM 2007; Youth athletes Youth Sports Safety Alliance NATA Guidelines from professional orgs ie ACSM, AMSSM

29 Injury prevention comes in various forms Team physician can influence all of the factors Conditioning/Training ACL, Hamstring & Ankle Sprains Limitations Lots of available resources Be proactive!
