Context: Shoulder injuries are frequently sustained in American football due to the contact and collision aspect of the sport. Injuries to the shoulder account for about 10% to 20% of all musculoskeletal injuries that occur in football and the shoulder is the fourth most commonly injured joint behind the hand, knee and ankle. The effectiveness of the dynamic stabilizers of the glenohumeral joint is a factor that could affect the rate of injuries that occur at the joint. The CKCUEST has been shown to be an effective test for assessing the dynamic stability of the glenohumeral joint.
The purpose of this study is to determine if identifying and treating players can decrease the incidence of shoulder injuries in collegiate football players with poor dynamic stability at the glenohumeral joint. Design: Retrospective chart review.
Participants: 90 NCAA football players. The average age of subjects was 20.88 years (+/-1.52), the average height was 185.14 cm (+/-6.17), and the average weight was 99.92 kg (+/-18.42).
Intervention: The closed kinetic chain upper extremity stability test (CKCUEST) was used to identify subjects at risk for glenohumeral joint instability injuries. A shoulderstrengthening program was implemented into the summer workout program before the 2015 college football season. The CKCUEST was administered immediately before the 2015 season in August, 2015 and it was administered again after the end of the 2015 season. The incidence rate for glenohumeral instability injuries was calculated for the
