Description

Two-dimensional video analysis of the drop vertical jump test has been shown to be an effective and accessible screening tool in assessing an individual’s risk for anterior cruciate ligament injury. High degrees of dynamic knee valgus during landing from a drop vertical jump suggest increased risk for ACL tears, specifically in female athletes, who are at greatest risk. Activation of the stabilizing muscles of the hip has also been shown to play a role in reducing these knee movements that predispose an individual to ACL injury. The purpose of this study was to use the drop vertical jump injury screening protocol to assess ACL injury risk in female volleyball players before and after their participation in a six-week training program targeting the strengthening of the gluteus medius muscle. Two data collection sessions were completed six weeks apart. During both data collections, tape markers were placed on the hips, knees, and ankles of the participants. Five video trials of the drop vertical jump were recorded and analyzed to determine maximum knee valgus during landing from the drop vertical jump. Between the two data collections, the subjects participated in their regularly scheduled weekly training sessions, which included exercises for the gluteus medius muscle. The results from the pre- and post-training data collections were presented to the participants in a report including details of their risk classification, along with general recommendations for improvement. The pre- and post-training injury screening data were compared to evaluate the efficacy of the gluteal muscle strengthening program in decreasing risk factors associated with ACL injury.
