Acl prevention program

WHY?

  • Research shows there will be an estimated 100,000 ACL tears this year

  • Several research studies indicate that this injury is more common in female athletes

  • Several risks factors have been pinpointed for the increase in frequency in female athletes


Major factor for acl tear

Major Factor For ACL Tear

  • Instantaneous loss of motor control while in combination with landing with knees and hips straight

  • Good news is research is showing that a dedicated program with the right components can reduce this risk of injury


Literature review

Literature Review

  • Our focus group performed a thorough literature review to find studies that looked at ACL prevention

  • We came up with 24 studies that we decided to examine closer

  • Of those, 10 were Level 1 or 2 studies

  • We then further broke those 10 down


Research

Research

  • The evidence shows that neuromuscular training including plyometrics, balance, and technique training reduces the risk of serious knee injuries in female athletes

  • All current preventative programs are different but center on alteration of neuromuscular risk factors

  • Training may facilitate NM adaptations to increase joint stabilization and muscular preactivation and reactivation patterns which help protect the ACL


Research1

Research

  • Gilchrist, Mandelbaum, Silvers et al studied 1435 Division 1 Female Soccer players-Level 1 study

  • Program used PEP (Prevent injury and Enhance Performance) program 3x/wk during fall season

  • Results found ACL injury 1.7x less likely in intervention group


Research cont

Research cont.

  • Pollard, Sigward, Powers, et al studied 26 female soccer players between ages 14-17

  • Implemented the PEP program with soccer practice

  • Results- Players showed significantly less hip internal rotation and significantly greater hip abduction

  • Thus, PEP has been shown to alter LE kinematics


Research cont1

Research cont.

  • Mandelbaum and Silvers et al. In 2000- 1041 intervention group and 1905 in control group. Results: 88% less ACL injuries in intervention group

  • 2001-844 in intervention group and 1913 in control Results: 74% less ACL injuries in intervention group


Research cont2

Research cont.

  • Hewett, Ford, and Myer looked at 6 of their studies that included plyometrics, biomechanics technique feedback, balance and core stability training, and strength training

  • Results showed training decreased injury in 3 of the 6 studies and 5 of the 6 demonstrated positive trends and reduction in odds ratios

  • Results of the six studies:

  • Balance training alone is not as effective as when combined with other training

  • plyometric training should be included


Hewett cont

Hewett cont.

  • Strongest studies incorporated strengthening but it may not be a prerequisite for prevention

  • Training needs to be performed more than 1 time per week with a minimum duration of 6 weeks


Research cont3

Research cont.

  • Hewett’s team and Mandelbaum’s team each came up with their own separate programs

  • Hewett’s program was developed by the Cincinnati Children’s Sports Medicine Biodynamics Center and the Human Performance Laboratory

  • Mandelbaum’s program is labeled the PEP program as discussed earlier

  • Each program has exercises that pertain to all the components needed in order to reduce risk of ACL injuries


Voi acl prevention program

VOI ACL Prevention Program

  • Combination of the two programs that would accommadate for the amount of time available at each practice session to perform the exercises, to ensure every athlete could perform it with very little equipment, and to simplify the exercises to allow for ease of implementation


Components of program

Components of Program

  • Warm up

  • Stretching

  • Agility drills

  • Practice

  • Strength exercises

  • Cool Down


Components cont

Components cont.

  • Components are listed in the order that they should be performed

  • Warm up and stretching are to be done at the beginning of practice followed by the agility drills

  • Then, the athlete would be ready for a normal practice session

  • At the conclusion of practice, a brief strengthening session followed by the cool down


Warm up

Warm Up

  • Warm up is designed to get ready for practice activity and to help prevent injury.

  • Set up two markers about 10-20 yards away from each other and have the players perform the following 3 warm up activities about 2 minutes each:

  • Forward jogging- Have each participant jog forward from cone to cone. Hip, knee and ankle should be in alignment and make sure the knees are not falling in toward each other and that the feet are not moving out to the sides behind them.

  • Side shuffling- Have each participant shuffle sideways between the cones, make sure they maintain hip and knee in bent position and don’t travel standing straight up.

  • Backward jogging- Have each participant jog backwards from cone to cone, again maintaining hip, knee, and ankle alignment and not allowing knees to fall inward. They should also stay on their toes and not jog flat footed.


Stretching

Calf Stretch

Stretching

  • Correct

  • Instructions: Stand on your right leg, bend forward and put your hands on the ground in a V-form. Keep your right leg straight and your right foot flat on the ground.
