Brief Summary

In this pilot study the investigators are testing whether an injury prevention program will help improve quality of movement and decrease number of injuries in collegiate women's lacrosse athletes. The primary purpose is to determine whether an injury prevention program including individualized movement instruction along with an educational program is better than an educational program alone for improving movements that can increase risk of injury and decreasing number of injuries. The investigators will recruit women's lacrosse athletes from the San Diego State University women's lacrosse team. Enrolled participants will be divided up into two groups of 10 individuals. Both groups will participate in an injury prevention educational program including a lecture component with pictures and videos, and a practice component in which athletes will be provided with group instruction on how to perform the activities and then will have an opportunity to practice all activities. In addition to the educational program, athletes in the individualized movement instruction group will be provided individualized feedback on their movements when performing activities from the injury prevention program during 3 sessions throughout the season. The primary outcomes that will be evaluated include lower body movement during a jumping and balance task as measured using a 3D motion capture system. The investigators hypothesize that participants who receive the individualized feedback in addition to the education program will display greater improvements in movements that increase injury risk when compare to the education only intervention group.

Education

ACTIVE COMPARATOR

All participants will attend an educational training session on the team's Injury Prevention Program (IPP), which will be performed prior to practices and matches throughout the season. All team members, coaching staff, and medical staff will attend the educational session. This session will be administered during the pre-season training period, will last 60-90 minutes, and include a didactic component and a practical component in which all athletes on the team will receive instruction on how to properly perform each component of the IPP program. and have an opportunity to practice performing the IPP on the field. This is an evidence-based program that will be provided to all lacrosse athletes regardless of participation in the research study.

Individualized Feedback + Education

EXPERIMENTAL

After completing the Education Program, participants assigned to the individualized feedback group will perform the IPP during a strength and conditioning session while a research team member records their performance on a laboratory video camera. The video will be analyzed to identify errors and compensations with movements and a plan for a feedback session to correct movements will be developed. The feedback session will include showing the athlete their video, identifying the error or compensation, and providing verbal, tactile, and visual feedback to correct the error or compensation. Two additional feedback sessions will be scheduled at regular intervals during the season.

Interventions

Education Program on Injury Prevention BEHAVIORAL

The didactic component of the injury prevention education program includes information on prevalence of injuries in female athletes, biomechanical risk factors for injury, and effectiveness of injury prevention programs (IPP) for mitigation of injury risk. Examples of different activities from the IPP, including proper and improper movement strategies will be provided. Athletes will be instructed as a group on how to properly perform of each activity of the IPP, and will be given an opportunity to practice. Athletes, coaches, and staff will be provided with links to written instructions and videos of proper performance for each activity. The IPP will be performed at least 3 times/week prior to practice. Coaches, staff, and athletes will be encouraged to provide supervision and feedback on performance of the IPP throughout the season.

Education; Individualized Feedback + Education

Individualized Feedback + Education Program on Injury Prevention BEHAVIORAL

In addition to the education program, participants in this group will receive individualized feedback on performance of the IPP. The participant will be videotaped while performing the IPP, and movement errors and compensations will be identified to provide a basis for feedback sessions to correct movement. The session will include different forms of feedback including showing the athlete their video, identifying the error or compensation, and providing verbal, tactile, and visual feedback to correct the error or compensation. Common errors and compensations, along with verbal cues and corrections, have been identified and manualized for the study. Two additional feedback sessions will be scheduled at regular intervals during the season to provide feedback on performance throughout the season. Participants in this group will be encouraged to provide peer feedback to one another.
